Abstract:

Rigid polyurethane foam (RPUF) used for imitation wood is typically prepared by using 1-dichloro-1-fluoroethane (HCFC-141b) as a blowing agent. However, this chemical is a hydrofluorocarbon which severely causes ozone depletion to the atmosphere. In this study, a more environmental-friendly RPUF was prepared by using distilled water and cyclopentane (CP) as alternative blowing agent. Several properties of the prepared RPUF were investigated and measured such as density (kg/m3), surface hardness (Durometer, type D), and glass transition temperature (°C) using differential scanning calorimeter (DSC). It was found that when the amount of blowing agents decreased, the foam density was increased as well as the surface hardness. The developed RPUF with CP co-blown has higher surface hardness and glass transition temperature compare to pure water-blown RPUF at the same density (353 kg/m3). And the new RPUF produced has a good potential to substitute for a conventional RPUF.

Abstract:

Glass blowing to create bottles with specific thickness distribution profiles requires several experimental iterations. Such iterations are expensive and increase the time to market. The use of simulation pretends to decrease the amount of prototypes by doing virtual validation of glass blowing molds. To feed simulations with realistic physical values, a gob drop test has been designed. This test provides valuable experience on the use of the software and validates heat transfer, viscosity and other physical parameters. Gob drop test was chosen for the possibility to record the test with infrared thermal cameras. Gob obtained similar shapes when dropped on a cast iron plate for both central and side sections with longer cooling of about 25°C. Such technique allowed the user to gain experience on the use of software and obtain valuable physical parameters for future glass blowing optimization.

Abstract:

Production of glass bottles requires blowing of the glass after entrance of a gob of molten glass in the blank mould. The final shape of the bottle is highly dependent on the viscosity of the glass, the blow-pressure and the temperature distribution in the glass and the mould and simulation of this complicated process enables optimization of the process conditions. During simulation of blowing of the glass, the mesh has to be adapted due to the extreme deformations of the mesh. To reduce the user-time and to be able to run this kind of analyses automatically based on an arbitrary base-geometry, a completely automated remeshing/rezoning procedure is set-up. Using the automated remeshing capability, simulations of the glass bottle forming process have successfully been performed, enabling for example optimization of process settings.

Abstract:

Due to extremely low thermal conductivity, high modulus, high toughness, light weight and non-combustible property, ultrafine glass wool can be widely used as glass fiber reinforcements in composites, thermal insulation materials, acoustic insulation materials, engineering materials, construction, infrastructure and environmental protection projects and so on. In particular, as a insulation material, glass wool exhibits unique advantages. The predominant process of glass wool is centrifugal blowing process. This paper describes a study of the relationship between the diameter of ultrafine glass fiber and thermal conductivity. The thermal conductivity of ultrafine glass wool decreases with the decrease of average diameter.

Abstract:

Early Roman mould-blown glass vessels are widespread and well-known in the museums, private collections and sale rooms of Europe and America. However, one encounters such items less frequently in the regions where a great many of them were made. Although much work has been done on the origins and early practitioners of the craft of mould-blowing, few actual vessels have been recorded in the eastern Mediterranean and Middle East. So it is pleasing that I am able to add to the list a fine example in the Gaziantep Museum.Hexagonal flask. 1st century A.D. Translucent cobalt blue glass. Blown in a three-part mould. Flat bottom. Cylindrical neck with everted rim, lip folded inward. (Fig. 1 and Pl. XIX/a–c).Exact find-spot not recorded; acquired by purchase in the Gaziantep region. No registration number by October 1984.Height 7·8 cm. Diameter of bottom 2·4 cm.

Abstract:

In this essay the author discusses the benefits of introducing digital making tools into the glass artist’s practice-based research, both on a professional and student level. Using an example from his personal creative practice as a case study, the author outlines not only the practical benefits of using digital technology, but how when combined with traditional hot-worked glass techniques the synthesis can produce art objects that would otherwise be impossible using either digital or manual means alone. He argues that it is the possibility of inventing novel approaches to art making that can motivate glass artists and students to embrace digital means of making, rather than relying on appeals to practicality and efficiency alone. Includes a description of producing blown glass sculptures that combine fused water-jet cut sheet glass with traditional mold blowing and glass sculpting techniques.

Abstract:

A new type of sound absorbing material, which was made from super strength polyurethane and mass fiber, was investigated. And the sound absorption coefficient of the material was tested by standing wave tube method. Experiment results manifested that content of glass fibers, blowing agent and thickness have great effects on the sound absorbing performance of the sample. When the content of glass fiber and blowing agent are separately 3% and 0.4%, the performance of the material reaches optimum. The noise reduction coefficient of the material is 0.6, and the sound absorption property at middle-low frequency is good.

Foam glass is known mainly as a cellular thermal insulation material obtained by sintering a mixture of glass powder and a blowing agent followed by annealing of the foam material. This article explores the possibility of producing heat-insulating foam glass directly from widely available amorphous-siliceous natural flasks, eliminating economically disadvantageous and energy-intensive processes of cooking and granulation of special multicomponent glass melt from the scheme of traditional technology.

Abstract:

This author applied personal practice in order to develop and subsequently demonstrate the feasibility of applying the techniques of inside painting of traditional Chinese snuff bottles, so as to create a body of works demonstrating totally different effects and styles. The techniques focus on free-hand blowing in this section. This new form of inside painting shown could be applied to contemporary glass sculpture making and therefore reduce, or even solve, the monopoly of traditional style.

Full text

Abstract:

The industrial manufacturing of glass containers consists of several phases, one of which is the blowing phase. This paper describes the development of a numerical simulation tool for this phase. The hot liquid glass is modelled as a viscous fluid and its flow is governed by the Stokes equations. We use the boundary element method to solve the Stokes equations and obtain the velocity profile at the glass surface. The movement of the surface obeys an ordinary differential equation. We use the Euler forward method to perform a time integration step and update the shape of the glass surface. All calculations are performed in three dimensions. This allows us to simulate the blowing of glass containers that are not rotationally symmetric. The contact between glass and mould is modelled using a partial-slip condition. A number of simulations on model glass containers illustrates the results.   Please note that this article has three supplemental video files:<ol><li><a href="../../article/downloadSuppFile/917/13" target="_blank" title="Video 1">Video 1</a></li><li><a href="../../article/downloadSuppFile/917/14" target="_blank" title="Video 2">Video 2</a></li><li><a href="../../article/downloadSuppFile/917/15" target="_blank" title="Video 3">Video 3</a> </li></ol>

Abstract:

The article presents the results of a study of the state of production of a foam glass and the nomencla-ture of its products. It is shown that it is expedient to use the recycled glass obtained from the bottle battle, the defective glass and the double-glazed windows as a raw material for the production of the foam-glass. The re-quirements are formulated for glasses, which should have low viscosity values in the range of foaming tempera-tures. The features of the technology for the production of the foam glass aggregate at the specialized lines are outlined. The technology features are the composition of the charge and temperature conditions of burning. The mixture for the production of the foam glass aggregate consists of glass flour, organomineral blowing agent con-taining water and food glycerin, as distinct from the slab foam glass, where soot or coke is used as a blowing agent. The results confirm the effectiveness of the use of the foam glass aggregate as a soundproofing backfill for floors. Currently, about 70% of the foam glass aggregate is used for roofs and stylobates; the rest is used in landscape design, road construction, foundations and major repair. In the future, the areas of application of the foam glass aggregate can be significantly expanded in the direction of building systems, lightweight aggregates, etc., which involves in-depth studies of the properties of this material.

Abstract:

Vinylidene chloride copolymer microspheres were synthesized by in situ suspension copolymerization of vinylidene chloride (VDC), methyl methacrylate (MMA), and/or acrylonitrile (AN) in the presence of a paraffin blowing agent. The effects of shell polymer properties including compositions, glass transition temperature (Tg), crosslinking degree, blowing agent type, and encapsulation ratio (Er) on the expansion properties of copolymer microspheres were investigated. Moreover, the diffusion properties of blowing agent in copolymer microspheres were studied. The results show that VDC-MMA-AN copolymer microspheres exhibited excellent expansion properties, and the volume expansion ratio (Ev) and the apparent density were decreased over 40 times, but it was difficult to expand for the VDC-MMA copolymer microspheres. In addition, the moderately crosslinked inside of the polymer shell enhanced the Ev more than 30 and the stable expansion temperature range (Tr) was about 30 °C by adding 0.2–0.4 wt% of divinyl benzene. The Tg of the shell polymer must be higher than the boiling point of the blowing agent as a prerequisite; the lower the boiling point of the blowing agent, the higher the internal gas pressure driven microsphere expansion, and the wider the Tr. By increasing the Er of blowing agent improved the Ev of the microspheres. The diffusion of pentane blowing agent in VDC-MMA-AN copolymer microspheres were divided into Fick diffusion and non-Fick diffusion.

Abstract:

The earliest refractories for containing melts were quarried from natural deposits of limestone and dolomite. Today these two carbonate rocks serve important roles in the production of metal contact refractories. Early refractories for glass melting on the other hand were manufactured from clays and claystones. These materials are also still used extensively for the batch melting of glasses that are hand formed or blown into art and tableware. Glass contact refractories for the continuous (tank) melting of glass are often fired, cast into large shapes, and arranged in a soldier course which constitutes the sidewalls of the glass tank.In this brief exposition of refractories technology and allied research, the articles by B. Brezny, T.F. Vazza and T.A. Leitzel, and by T.S. Busby cover materials development, selection, and properties of the systems which have evolved for the efficient melting of steels and glasses. As such they relate to extremes of technological flux in the processes for the manufacture of steel and glass, respectively.The continuous melting of large volumes of commercial glasses has been carried out in tanks equipped with reverberators for at least 70 years. The basic design of the overall system and of many of the glass fabrication machines for pressing, rolling, and blowing the glass has been constant since World War I. Only the introduction of the float glass method, the famous Pilkington process, for the production of flat glass, has interrupted the slow quiet progress in the technology of continuous glass making.

Water blown biobased thermoplastic polyurethane (TPU) foams were prepared using synthetic and biobased chain extender. The concentration of chain extender, blowing agent (BA) and surfactant were varied and their effects on physical, mechanical and morphological properties of foams were investigated. Density, compressive strength and modulus of foams decreases with an increase in BA content and increased with chain extender concentration, but do not change significantly with change in surfactant concentration. The glass-transition temperatures of the foam samples increases with an increase in BA and chain extender concentration. The cell size of the foam sample increases slightly with an increase in BA whereas chain extender concentration has no effect on cell size.

Abstract:

Light glass fiber felt (density 10 kg/m3), a porous composite consisting of 83% glass fibers (the average diameter 1.5 µm) and 17% phenolic resin, is usually used to increase sound insulation in the aerospace industry. The purpose of this research is further to improve the uniformity of light glass fiber felts by process optimization, analysis of microstructural forming mechanisms and physical properties. Light glass fiber felt is produced by the flame blowing process. The results show that process optimization can effectively improve the uniformity of light glass fiber felt. Light glass fiber felt exhibits a micro-layer structure seen as consisting of a number of “three-layer” structures, that is dense (more fibers)-loose (less fibers)-dense structure. In addition, process optimization can improve the stability of permeation rate and enhance sound insulation performance, which makes light glass fiber felt an excellent sound insulator.

Abstract:

Composite foamy structures were prepared through hollow glass microspheres (HGM) assisted bubbling of silicone rubber with ammonium hydrogen carbonate as the blowing agent. The presence of HGM not only favoured the foaming process (acted as nucleating agent for the formation of minute bubbles at the initial stage of the bubbling), but also bring heterogeneous close-cell bubbles with stable inorganic shells into the foamy structure, which played an important part in the improvement of the heat insulation property of the product. Compared to the foamy structures without HGM, The composite foamy structures possessed improved heat insulation and sound absorbing properties. This work provides an additional strategy to fabricate composite foams with tailored cell structure and properties.

Abstract:

The VIPs consist of the glass-fiber core material and two types of envelope film. The glass fiber was fabricated by a centrifugal blowing process. The core material was prepared by the wet method. The thermal conductivities of the core material and VIPs were measured by the heat flow meter. The thermal conductivity for six pieces of 1mm thick core material is less than that for one piece of 6mm thick core material, which is affected by the fiber diameter, porosity ratio and the largest pore size diameter. The VIP for the building material has a low thermal conductivity (<0.008W/mK). The VIP for the home appliance has a lower thermal conductivity (<0.003W/mK). The VIP maintains a high-uniform thermal conductivity values due to the getter effect.

Abstract:

Melt blown (MB) fabrics are composed of fine fibers which contribute to high filtration efficiency (FE) and low air flow resistance compared to high efficiency filtration media such as fiber glass paper. Furthermore, MB fabrics are mostly made of polypropylene (PP) polymer, which can be electrostatically charged to enhance the media filtration efficiency without the increase of air flow resistance. However, different charging techniques or charging at different locations on the MB line will contribute to different filtration efficiency. This paper compares the efficiencies of different charging techniques in the MB line.

Abstract:

Among the most dramatic changes in ancient material culture was the widespread adoption of glass vessels for tableware and storage during the 1st c. B.C. and 1st c. A.D. As shown by the quantity of glass finds from occupation sites of the Imperial era, glassware was much more prominent in daily life than it had been previously. This shift occurred concurrently with the widespread adoption of glassblowing. This change in consumer behavior points to a complex process of experimentation, development, and gradual adaptation on the part of both producers and consumers. The transition from centuries-old technologies of core-forming, casting and sagging to blowing required a complete reconfiguration of every stage of glass production, from the increased supply of raw material to the development of new tools and workshop space, and in the training of craftsmen.

Abstract:

Successful technological change in countries outside the northern Atlantic during the nineteenth and early twentieth centuries depended on entrepreneurial skills, not inventive expertise. In this examination of the Owens automatic glass-bottle-blowing machine in Mexico between 1905 and 1912, innovation is seen to have occurred within a broad context of incipient social and economic modernization. Although the obstacles encountered by technology importers and innovators were both substantial and stubbornly persistent, in this case, they turned out to be malleable.

Abstract:

Obtained artificial substrates, representing a porous glass (foam glass) with additives of 3 to 10% of the mass. copper ions. Glass raw materials were used as raw materials for the synthesis of substrates. In order to create open porosity, a carbonate blowing agent (chalk) was introduced into the initial mixture. Foaming additive served as sodium nitrate, a source of copper ions - copper sulfate (copper sulfate). A distinctive feature of the synthesis method was the combination of wetting the initial mixture and its rapid heating to maximum temperature. This mode was used to increase the porosity of the resulting structure. It was found that the water absorption of the obtained substrates increases with an increase in the concentration of copper ions in them. The resulting materials, due to the increased content of copper ions in them, may have a fungicidal effect. Perhaps their use in crop production, landscape design, the construction industry in conditions of high humidity.

Abstract:

This paper explores the mechanism design of a balloon machine representing a vending machine where consumers can select their desired shapes, as well as avoid bursting caused by manual inflation. Inside the machine, balloons are placed on the mechanism designed based on a waterwheel which rotates at a constant speed generated by motion among different sizes of gears. When rotating to the corresponding shaped balloon, the inflator will move under the opening to pull it out from the display point and start to inflate the balloon for the set number of seconds. After the inflation is completed, the glass door will open and the customer can take out their balloon. The main purpose of our development and design of the balloon machine is to improve the general balloon blowing and it is easy to prevent over-exposure and blast. The balloon machine can automatically inflate and detect the blowing time to improve the shortcomings of the balloon’s blast. In this way, it can effectively decrease sudden explosions and the number of frightened people.

Abstract:

In order to improve the structure, section shape and inner flow performance of micro-channel in Micro-fluidic system, a novel fabricating process of bio-micro-channel (BMC) is proposed based on the softening and forming property of glass material. By the manipulation of heating, pulling and blowing, a bio-micro-channel is made from glass capillary with specific functional units. A vitreous bio-micro-channel fabricating device (VBMCFD) is presented with working models of uniaxial and biaxial tension. Using common borosilicate glass capillary as experimental material, the affecting parameters of micro channel inner diameter, outer diameter, thickness and functional unit key parameter are tested, such as heating voltage, heating time, pulling velocity, pulling displacement and inner pressure. The bio-micro-channel is fabricated with micron scale inner diameter, about 5μm, and spherical functional unit. The experimental results show that the prototype of VBMCFD is characterized by reliable process, simple structure, low cost, etc. The vitreous bio-micro-channel is fabricated with circular-cross-section straight channels and uniform functional units, which are the key characters of biologic micro-channel.

Abstract:

Introduction. Foam glass is often represented as a thermal insulation, a sound insulation and a sound absorbing material in the form of blocks (slabs), granules and shaped products. Cellular glass is characterized by durability, incombustibility, biostability and sufficient strength. Among the main properties, it is also possible to mark out low thermal conductivity of foam glass which makes it a promising thermal insulation material. Materials and methods. A complex of general scientific logical methods of research is used in this work. The complex is based on a theoretical analysis of technological solutions for the foam glass production described in the scientific and technical literature, patents as well as scientific papers. Results. Possible classifications of foam glass products are marked out; an authors’ classification is suggested depending on the field of foam glass application. The main foam glass properties are considered. The advantages and disadvantages of the foam glass charge mixture are identified in the course of analysis of possible raw components as well as their influence on the foam glass production technology and properties of the finished product are examined. Comparison of blowing agents is conducted depending on the foaming temperature and pore character that affect the field of material application. A comparative table of the foam glass production technologies is proposed, the merits and demerits of each technological solution are revealed as well as variants of the obtained products and needed equipment are considered. Conclusions. Allowing for the consumer demand for thermal insulation materials and strict requirements for them, it is most expedient to produce granulated foam glass with a wet method. The advantages of this technology are the accelerated grinding of glass in liquid media, lowering the foaming temperature, expanding the temperature range of structure formation, eliminating dust emission that permits reducing the finished product cost.

Abstract:

The automobile and aerospace industries require lightweight and high-strength structural parts. Nylon-based microcellular foamed composites have the characteristics of high strength and the advantages of being lightweight as well as having a low production cost and high product dimensional accuracy. In this work, the glass fiber-reinforced nylon foams were prepared through microcellular injection molding with supercritical fluid as the blowing agent. The tensile strength and weight loss ratio of microcellular foaming composites with various injection rates, temperatures, and volumes were investigated through orthogonal experiments. Moreover, the correlations between dielectric constant and injection volume were also studied. The results showed that the “slow–fast” injection rate, increased temperature, and injection volume were beneficial to improving the tensile strength and strength/weight ratios. Meanwhile, the dielectric constant can be decreased by building the microcellular structure in nylon, which is associated with the weight loss ratio extent closely.
