Abstract:

Non-linear insulating material is widely used in the insulations of XLPE cable terminations and stator windings insulation of electric machines, and has obvious capability to improve the distribution of electric field. Actually, the dielectric loss factor of non-linear insulating materials is not equal to the tanδ describing linear insulating materials, and depends on applied voltage and their structures. This paper firstly discusses the difference between ac loss characteristic of non-linear dielectrics and linear dielectrics and presents a kind model of non-linear composite material. Based on the model, specific characterization and measurement methods and their numeric simulation analysis are given. Finally, a measuring system for non-linear insulating materials based on digital measuring technology is presented.

Abstract:

This research studied the feasibility of using natural fibers extracted from natural wastes as a thermal-insulating material lined in a Kraft paper box packaging. The natural fibers were extracted from natural waste of rice straws using NaOH solutions. The extracted fibers were then formed as a porous thermal-insulating pad by a spray lay-up method using natural rubbers as binders. The thermal conductivities, specific heat capacities and temperature-rise time of the natural fiber insulation and other thermal-insulating materials including polystyrene foam, a polyethylene foam, and a glass fiber insulation were studied and compared. The glass fiber insulation showed the highest thermal conductivity, while the thermal conductivities of the other studied insulating materials were found to be similar. Moreover, the polymeric and natural-fiber insulations show better temperature-rise resistance than the glass fiber insulation. The temperature rises for different insulating materials were estimated using the analytical analysis of heat transfer. The calculated temperature-rise times were compared with the empirical results; both results are in the same order of magnitude. Consequently, a Kraft paper box lined with natural-fiber pads was constructed and compared with a Kraft paper box (without insulation lining) and a polystyrene box of equal sizes. The boxes were packed with an equal amount of ice and left under room temperature for 24 hours. The results show that, after 24 hours, the temperatures inside the natural-fiber lined box and the polystyrene box were contained below 15 °C, while the temperature inside the Kraft paper box increase to room temperature only after 16 hours. The observation shows that a natural fiber pad can potentially be used as an alternative insulating material in packaging industries, which can enhance environmental-friendly packaging products.

Abstract:

In order to protect the environment in present-day society, green buildings are seen as an effective and logical solution. Insulating materials are frequently widely used in green buildings to reduce their energy dissipation. China, as a global power, is at the forefront of ecological development. This paper will focus on the study of thermal insulations in the context of green concepts, a specific analysis of their properties and examples of their application in China. It is found that most of the green developments lack economic support and therefore, insulation materials need to be developed in the direction of low cost and high efficiency and effectively reduce their harmful effects on the environment. Furthermore, the development of insulation materials in China should pay attention to geographical differences, i.e. the insulation materials that can be applied in different regions in the North and South are different. This study will facilitate the application of insulating materials in China's ecological development, reducing related energy losses and protecting the surrounding environment.

Mineral/synthetic oil liquid insulation—together with solid insulation materials (paper, pressboard)—is the fundamental insulation constituent in HV apparatuses; their insulation attributes perform a substantial part in a reliable and steady performance. Meanwhile, implications on the environment, scarcity of petroleum oil supplies and discarding complications with waste oil have stimulated investigators to steer their attention towards sustainable, renewable, biodegradable and environmentally friendly insulating substances. The contemporary insulating constituent’s evolution is driven by numerous dynamics—in particular, environmental obligations and other security and economic issues. Consequently, HV equipment manufacturers must address novel specifications concerning to these new standards. Renewable, sustainable and environmentally friendly insulating materials are continuously substituting conventional insulating items in the market place. These are favorable to traditional insulating materials, due to their superior functionality. The also offer explicit security and eco-friendly advantages. This article discusses cutting-edge technology of environmentally friendly insulating materials, including their fabrication, processing and characterization. The new renewable, insulating systems used in HV equipment are submitted and their fundamental gains stated in comparison with conventional insulating materials. Several experimental efforts carried out in various parts of the world are presented, offering an outline of the existing research conducted on renewable insulating systems. The significance of this article lies in summarizing prior investigations, classifying research essence, inducements and predicting forthcoming research trends.

Abstract:

Production of building materials is mostly energy consuming. In the sphere of insulation materials we mostly see rock wool based materials or foam-plastic materials whose production process is demanding from material aspect and raw materials aspect as well. At present the demand for thermal insulation materials has been growing globally. The thermal insulation materials form integral part of all constructions in civil engineering. The materials mainly fulfill the thermal insulating functions and also the sound-insulating one. The majority of thermal insulation materials are able to fulfill both of the functions simultaneously. The paper describes questions of thermal insulation materials development with good sound properties based on natural fibres that represent a quickly renewable source of raw materials coming from agriculture. The main advantage of the materials are mainly the local availability and simple renewability of the raw materials. In addition an easy recycling of the materials after their service life end in the building construction and last but not least also the connection of human friendly properties of organic materials with advanced product manufacture qualities of modern insulation materials.

Abstract:

Energy efficiency of heating networks depends on the costs of the manufacture of insulation materials and components, its installation and exploitation of insulating jacket. As insulation materials for insulation of heating networks, products based on rock wool, polyurethane foam extruded polystyrene foam, foam rubber and polyethylene foam. In this contribution introduced basic principles of calculating the thickness of the thermal insulation of a pipeline by the value of the standard density of the heat flow are given using an example of the use of products based on polyethylene foam. Calculation of the heat flux from the surface of the heat-insulating structure is carried out at a given thickness of the heat-insulating layer if there is a need to determine heat loss (or cold loss). The basis for the calculation is a mathematical model of heat transfer, a developed calculation algorithm and a computer program. The method of installation of thermal insulation depends on the diameter of the pipeline and the selected type of product. Insulating cylinders or cylinders in combination with heat-insulating mats are used for pipelines of small diameters. Roll materials are used to isolate large diameters. Products are fixed on pipelines using mechanical fasteners.

A group of employees of the Scientific, Educational and Production Laboratory "Outboard Boat Motors" of the Department of Water Transport Operation of the Federal State Budgetary Educational Institution "AGTU" achieved certain results in the fight against noise, reflected in a number of patents of noise-insulating hoods of various modifications and publications on the analysis of the frequency spectrum of outboard boat motor noise, evaluation of the effectiveness of outboard motor hoods of small-sized Based on the accumulated scientific research, several proto-types of multilayer means recommended for sound insulation of outboard boat motors have been created. In the conditions of a large range of directions, there is a need to apply single-layer or multi-layer structures to the properties of sound insulation without forming a physical model of the hood, casing. This is due to the fact that the production of a hood model entails a complex technological process, while creating a sample in the form of a plate from the same material is much more profitable in terms of financial, labor and time costs. Based on the needs of the scientific educational and production laboratory of outboard boat motors in the study of noise generated by outboard boat motors and means of combating them, it was decided to create a stand to assess the effectiveness of noise-reducing materials, which will allow modeling the conditions of natural operation of a noise-insulating material without the use of full-scale tests with outboard by motor. The created stand allows testing in two directions. The first direction is the testing of physical models of casings for noise insulation using audio files reproducing the noise of the required equipment. The second direction is the study of materials for their noise-insulating properties when generating waves of different frequencies.

Abstract:

Thermal restoration of building constructions presents a complex of measures during renovation and life prolongation of buildings. It is a solution including restoration of bearing parts of the construction, solutions of moisture questions and the thermal insulation and new surface treatments of the construction. After application of the thermal insulation total energy intensity for heating and cooling is reduced and the thermal comfort inside insulated object is improved. Nowadays at application of thermal insulating systems a huge amount of insulants produced from non-renewable materials (EPS, PUR) is needed or the production of these is energy demanding (rock wool). Some of them, namely foam-plastic insulating materials are not compatible with original walling materials and after its application the diffusion flow is frequently limited in direction to exterior. The paper describes possibilities of production of insulants from flax waste and use of such insulating materials in the field of exterior heat insulating materials for existing objects.

At present we can often see a development of new perspective materials using waste raw materials and not only in building industries. Still growing industrial waste amount together with not utilizable substances whose recycling is quite energy and finance demanding are the reasons. In addition it also brings a notable stress for the environment which further influences human health. The paper deals with a development of insulating materials based on waste PUR granulate generated as waste during PUR foam panel shaping. The aim was to develop insulating materials with good thermal insulation and eventually acoustic properties as suitable alternatives to present commonly used insulation materials in the market. Cement and subsequently PUR foams were selected as binders for waste granulate. Utilization of secondary raw materials in order to get new insulating materials with high added value is contribution of such a development.

Abstract:

The insulation materials are widely used in petrochemical, power engineering and other industries. The thermal insulation materials play an important role in the energy saving of district heating systems and in the building sector. In this work, the thermal conductivity of rock wool with different levels of moisture content and density of the insulation material was investigated by an experimental method. Experimental studies were carried out on rock wool from three different manufacturers. The effect of the wetting and drying cycle on thermal conductivity and density of the insulating material is analyzed. The thermal conductivity of the insulating material was measured using the guarded hot plate method. It was found that the thermal conductivity of insulating materials significantly affected the moisture content. The increase in thermal conductivity was from 1.33 to 4.42 times, depending on the density and the manufacturer of the rock wool. The wetting and drying cycles increase the thermal conductivity and density of the insulating material up to 2 and 2.5 times, respectively.

Abstract:

Abstract Sustainable thermal insulating materials produced from cellulosic fibers provide a viable alternative to plastic insulation foams. Industrially available, abundant, and inexpensive mechanical pulp fiber and recycled textile fiber provide potential raw materials to produce thermal insulating materials. To improve the fire retardancy of low-density thermal insulating materials produced from recycled cotton denim and mechanical pulp fibers, bio-based fire retardants, such as sulfonated kraft lignin, kraft lignin, and nanoclays, were coated onto sustainable insulating material surfaces to enhance their fire retardancy. Microfibrillated cellulose was used as a bio-based binder in the coating formula to disperse and bond the fire-retardant particles to the underlying thermal insulating materials. The flammability of the coated thermal insulating materials was tested using a single-flame source test and cone calorimetry. The results showed that sulfonated kraft lignin-coated cellulosic thermal insulating materials had a better fire retardancy compared with that for kraft lignin with a coating weight of 0.8 kg/m2. Nanoclay-coated samples had the best fire retardancy and did not ignite under a heat flux of 25 kW/m2, as shown by cone calorimetry and single-flame source tests, respectively. These cost-efficient and bio-based fire retardants have broad applications for improving fire retardancy of sustainable thermal insulating materials.

An alkaline activator and aluminosilicate materials react chemically to create geopolymers, which have a three-dimensional network structure and high thermal insulation properties. The use of geopolymer mortars as an insulating material in pond construction is discussed in this abstract, along with its composition, characteristics, and advantages over more conventional choices. Geopolymer mortars are used in ponds to promote energy efficiency and sustainability while also improving temperature stability and reducing water loss from evaporation. The utilization of geopolymers as cutting-edge insulating materials for structures with green roofs is thoroughly examined in this publication. As sustainable construction techniques become more prevalent, selecting the right insulating materials is essential for enhancing energy efficiency and overall building performance. Geopolymers, which can be produced from industrial waste or natural resources, offer appealing properties for green roofs, such as the ability to lessen the impact of urban heat islands, superior thermal insulation, and fire resistance. This study assesses the advantages, challenges, and potential impact of geopolymer-based insulating materials on green construction practices.

Abstract:

The results of research into the properties of modern textile materials, in particular, insulating materials, are presented for choosing a package of textile materials that will be the most effective in terms of quality for the production of a special-purpose jacket that will be used in low-temperature conditions. As insulating materials for the study of consumer properties of textile material packages, the material вЂњTinsuletвЂќ, batting and sintepon, upper fabric вЂњOxfordвЂќ, lining fabric вЂњNylonвЂќ were used. Both the materials themselves and the packages of textile materials from the top fabric вЂњOxfordвЂќ, insulation material and lining fabric вЂњNylonвЂќ were studied. It is assumed that the choice of insulating material is among the presented assortment on the market of Ukraine. It was established that the most effective package is the package using the insulating material вЂњTinsuletвЂќ. This package is characterized by the highest indicators of breaking load and air permeability, as well as the lowest surface density. All tested materials meet the requirements specified in DSTU EN 14058:2008. Today it is becoming relevant to study and compare the properties of the insulation material вЂњTinsuleitвЂќ with the materials of batting and sintepon, which are actively used by manufacturers in Ukraine. Therefore, it became necessary to compare the performance of one of the most modern insulating materials, вЂњTinsuleitвЂќ, with batting, which has been used for about a hundred years, but which is almost gone in Europe and the USA. Rational results, which testify to the absolute superiority of the insulation material вЂњTinsuleitвЂќ, were provided when evaluating the indicators of breaking load, air permeability, surface density of the insulation materials вЂњTinsuleitвЂќ, sintepon, batting, top fabric вЂњOxfordвЂќ and lining fabric вЂњNylonвЂќ separately and in composition of packages of textile materials. Therefore, in the case of replacement in the production of special clothing, insulation materials of batting and sintepon with вЂњTinsuleitвЂќ during the production in Ukraine, the term of use of special clothing will be significantly increased due to the improvement of strength properties, and the economic efficiency of its use will significantly improve. Increasing breathability and reducing the weight of clothing will provide opportunities for longer stay in low temperature conditions and have greater mobility and mobility of the consumer, thanks to which the demand for this special clothing will only grow.

Abstract:

The insulation performance of cable insulating materials can be optimised via matrix modification. Typically, low-density polyethylene (LDPE) is used as the matrix, and a certain proportion of nanoparticles are added to this matrix. To explore the effects of nanoparticles with different forms on the structural interface and crystal morphology of the material, nano-MMT and nano-ZnO were added to LDPE, and comparative experiments were carried out. Based on microscopic test results, material insulation performance changes before and after optimisation were observed. Then, simulation cable models with different insulating materials were developed. Based on the simulated electrical measurements, the thermal breakdown performance of the different insulating materials was tested. According to infrared stereo vision detection results, anomalous temperature points in the cables can be located accurately. Finally, based on macroscopic test results, we verified whether the inorganic, insulating nanomaterials meet the requirements for high-voltage transmission.

Abstract:

Increasing the thermal efficiency of drying and firing processes of ceramic products plays an important role for industries that want to remain competitive in the market. Thus, this work aims to evaluate the influence of the type and thickness of thermal insulations, applied on the external sidewalls of an intermittent ceramic kiln, on heat transfer, temperature distribution in the insulating material, maximum external surface temperature, and energy gain, compared to the kiln without thermal insulation. All proposed mathematical formulations are based on the energy conservation, and mathematical procedures are implemented in Microsoft Excel software. Here, it was tested four types of thermal isolators: fiberglass, rockwool, calcium silicate, and ceramic fiber. Results indicate that the greater the thickness of the thermal insulation, the lower the maximum external surface temperature and the greater the energy gain when compared to the kiln without thermal insulation. In addition, fiberglass is the insulating material, among the four types analyzed, which provides greater energy gain and greater reduction in maximum external surface temperature.

The article studies one of the aspects of the heat-insulating multifunctional shells use - the cold preservation. Such task is relevant for cold storages, workshops and warehouses, in which low temperatures constant maintenance is necessary, for sports facilities (for example, ice rinks and ski facilities). In all cases of application, the main goal is to achieve the economic efficiency, which is expressed in functional results (preservation of the material that breaks down at positive temperatures) and in energy savings. The use of polyethylene-based shells, which are connected by a lock joint, is substantiated. The experimental studies results of the material given in the article shows that in terms of resistance to low and alternating temperatures, operational durability, tensile strength and water absorption, this material and insulating shells based on it are quite applicable for insulation of cold-saving objects. The experience of using heat, vapor and moisture insulating shells based on polyethylene foam with the equipment of frameless and frame structures, sports facilities, as well as for the preservation of snow at ski resorts is also provided in the article.

Abstract:

The paper analyzes the problems associated with the fire hazard of the application of thermal insulation and finishing systems of facades of buildings, which directly depends on the design solution of the thermal insulation system and the type of thermal insulation material. The generalized requirements for physical and technical indicators of the quality of heat-insulating materials; the possibility of applying facade heat insulation structures depending on their class, the height of the houses and the combustibility of the materials of the heat-insulating and finishing layers; fire-technical characteristics of expanded polystyrene are considered. The threats of fire spreading by thermal insulation systems of facades are analyzed and possible ways of its propagation between floors are considered. It is concluded that the use of combustible thermal insulating materials poses an increased danger to life and health of people during a fire. The problem of ensuring the fire safety of buildings, in which the insulation and finishing systems of exterior walls are used, depends on a number of factors and requires a more thorough study.

Abstract:

Insulation is considered one of the effective solutions to achieve energy savings in buidings. Better insulation having low thermal conductivity contributes significantly to new construction and retrofitting existing buildings. The Energy Conservation Building Code and National Building Code of India define the prescriptive and mandatory requirements for the U-factor and R-values for different climates but the way to achieve these values is left to the designers. As none of the walling and roofing assemblies in buildings fulfill the criteria for overall thermal transmittance, the study deals with determining the thermal conductivity of sustainable walling materials and prefab roofing technologies as well as insulating materials using Guarded Hot-Plate Apparatus. The MATLAB program is developed for computing the U-values and for predicting the desired retrofit insulation thicknesses to make different materials and roofing assembly combinations comply the Code requirements in different climatic regions of India. The results of the study are used for computing the performance with and without insulation using DesgnBuilder software for improving energy efficinecy of the buildings in composite climate in India.

Abstract:

Transformers are an essential part of power production. Insulating paper began to be widely used in transformers in the 1990s. The superior aramid nanofiber as the matrix gives the aramid nano-insulating paper excellent mechanical properties, insulation performance, temperature resistance, and flexibility. At first, the heat resistance and service life of insulating paper should be satisfied for use in electrical equipment. With the continuous development of power equipment, people have put forward higher requirements on the properties of insulating paper, especially heat resistance and electrical properties. Insulation paper made of aramid fibers have better thermal stability and more advantages in electrical and mechanical properties, which can significantly improve the service life and safety of electrical appliances. The purpose of this article is to study the use of aramid nanopaper-based insulating materials in transformers to explore the effect of transformer discharge mechanism on aramid nanopaper-based insulating materials. This paper proposes to design multiple deep learning models to identify the discharge mode of the voltage transformer, find the characteristic signal, and carry out related tests on the discharge signal of different modes, and find the maximum temperature value of the aramid nanopaper-based insulating material for industrial use. The experimental results in this paper show that the aramid nanopaper-based insulating material can be used in transformers discharge detection well, and the safety rate is increased by 20%.

Abstract:

The characteristic feature of the modern construction industry is the broad appliance of contemporary design and technology solutions, which require new constructive, water-proof, finishing and heat-insulating materials. Implementation of new energy saving norms for the residential sector and increasing requirements for thermal protection of buildings have sharpened an issue how to develop new thermal insulation materials. Although the thick-layered heat insulation is known for a while, the heat insulation made of thin layers requires additional studies. This group of constructive materials is relatively new; there is no equipment and techniques for studying that. The structure of these materials is composite, comprising hollow ceramic and glass microspheres and a binder substance. This combination lends the lightness to the material and makes it highly adhesive to a surface where it should be applied. After application to a surface, the microspheres create a multilayered combination, reflecting up to 80% of heat stream. It makes the premises more comfortable, cutting down the expenditures on heating in winter, and summer air conditioning as well.

Abstract Improving the thermal performance of the building envelope and reducing the energy consumption of heat transfer are particularly important for building energy conservation. Wall insulation materials can be divided into sintered and non-sintered two types. Sintered wall insulation materials have unique advantages in the development of self-insulating wall because of their high strength, good insulation ability and wide range of raw materials. In this paper, the research status of shale, fly ash, coal gangue and phosphogypsum as raw materials to develop wall insulation materials are introduced, feasible research direction in view of the significantly reduced thermal performance and durability of sintered self-insulating wall materials in high humidity environment and high sintering temperature are put forward. The research on the formation and control mechanism of high closed porosity structure and the action mechanism of multiple fluxes can provide theoretical support for the design and optimization of self-insulation wall materials with light, high strength, low sintering temperature and meeting the requirements of building energy conservation.

Abstract:

Soft magnetic composites (SMCs) such as FeNi50 are indispensable in modern electronics due to their high magnetic permeability and low-loss characteristics, meeting the requirements for miniaturization and high-frequency operation. However, the integration of organic materials, initially aimed at reducing the total losses, presents challenges by introducing thermal stability issues at high frequencies. To overcome this obstacle, we propose a double-layer insulating coating method, applying a complete inorganic/organic composite insulation layer to the surface of iron–nickel magnetic powder. The double-layer insulating coating insulation method aims to reduce the total losses, particularly the eddy-current losses prevalent in SMCs. Additionally, the double-layer insulating coating method helps alleviate the thermal stability issues associated with organic materials at high frequencies, ultimately enhancing the magnetic properties of SMCs. We systematically investigated the influence of different resin types on the microstructure of the double-layer insulating coating, accompanied by a comprehensive comparison of the magnetic properties of the resulting samples. The experimental findings demonstrate a significant reduction in the eddy-current losses through the double-layer insulating coating method, with the total losses decreasing by over 95% compared to the initial FeNi50 magnetic powder composite (MPC) materials. Notably, the sodium silicate and silicone resins exhibited superior performances as double-layer insulating coatings, achieving total loss reductions of 1350 W/kg and 1492 W/kg, respectively. In conclusion, the double-layer insulating coating method addresses the challenges related to the total losses and thermal stability in SMCs, offering a promising approach to improve their performance in various electrical and electronic applications.

Since in modern shipbuilding safety and comfort demands of the interior of the vessels are high, so the requirements for insulation materials on the interior are also high. Various characteristics of insulating and sewing materials, which determine their quality level, were analyzed in details. When studying the characteristics of insulating materials, the technological level and competitiveness of the manufacturer were taken into account. To determine the most suitable insulation material for the interior decoration of the floating restaurant, multi-criteria comparison method was first applied.

Abstract:

Abstract The use of super insulating materials in the construction industry, including vacuum insulation, closely corresponds to the ever-increasing requirements for the construction of low-energy and passive buildings. Their indisputable advantage is their excellent thermal insulation properties at low thickness compared to conventional thermal insulation materials. However, there are also many risks associated with the experience and practice of the personnel involved in the application of these materials to structures. The paper focuses on the overall comparison of the possible use of vacuum insulation panels in modern building structures in terms of possible design solutions and achieved properties. The paper presents the results of selected case studies of the optimal use of vacuum insulation panels (VIP) in the construction industry, which are focused on different areas of building structures, specifically on the detail of the transition of the terrace and the adjacent floor, as well as on the solution of the filling of openings - doors. Based on the results of the studies carried out, it can be concluded that, provided that all procedures for maintaining the VIP properties are followed in the implementation of these materials in structures, vacuum insulations represent a more suitable solution for structural details in selected details (less thickness and comparable thermal insulation properties compared to conventional insulations).

Abstract:

After a century of practice, cellulose insulating polymer (insulating paper/pressboard) has been shown to be one of the best and most widely used insulating materials in power transformers. However, with the increased voltage level of the transformer, research has focused on improving the insulation performance of the transformer’s cellulose insulation polymer. Considering the complex environment of the transformer, it is not enough to improve the single performance of the insulating polymer. In this study, a nano-structured ZnO-Al2O3-PTFE (polytetrafluoroethylene) multifunctional film was deposited on the surface of insulating pressboard by radio frequency (RF) magnetron sputtering. The effect of the multilayered ZnO-Al2O3-PTFE functional film on the dielectric and water contact angle of the cellulose insulating polymer was investigated. The scanning electron microscopy/energy dispersive spectrometry (SEM/EDS) showed that the nano-structured ZnO-Al2O3-PTFE functional film was successfully deposited on the cellulose insulation pressboard surface. The functional film presented an obvious stratification phenomenon. By analyzing the result of the contact angle, it was found that the functional film shields the hydroxyl group of the inner cellulose and improves hydrophobicity. The AC breakdown field strength of the treated samples was obviously increased (by 12 to ~17%), which means that the modified samples had a better dielectric insulation performance. This study provides a surface modification method to comprehensively improve electrical properties and the ability to inhibit the moisture of the cellulose insulating polymer, used in a power transformer.
