The present work investigates the physicochemical stability of spray paints when irradiated with artificial solar light (at spectral range 300–800 nm). This research highlights the importance of understanding the materials used in street art and public murals, recognising them as a significant component of contemporary cultural heritage. By examining the stability and degradation of spray paints toward solar light exposure, the study aims to contribute to the preservation of contemporary murals, which reflect current social and cultural narratives. A physicochemical approach was employed for t

Using a sample coated with three types of carbon-based paints, namely single-wall carbon nanotube (SWCNTs), carbon black, and graphite, the amount of radio wave absorption for each was measured. SWCNTs proved to have the superior radio wave absorption effect in the millimeter band. Considering the change in the amount of radio wave absorption depending on the coating amount, three different coating thicknesses were prepared for each test material. The measurement frequency was set to two frequency bands of 28 GHz and 75 GHz, and the measurement method was carried out based on Japanese Industri

The heritage of fair-faced concrete, largely built in the twentieth century and nowadays recognized as heritage to be protected, is susceptible to attacks by graffiti, a form of vandalism that causes a major social and economic impact on society. Concrete is a porous material sometimes deteriorated over the years, and the interactions between the inks and the substrate and removal methods sometimes deteriorate or alter the concrete surface, especially if it is necessary to repeat the removal process.

Spray painting robots equipped with air spray guns have been widely used in the painting industry. In view of the low efficiency of single-nozzle air spray guns when spraying large targets, a new double-nozzle air spray gun structure was designed in this paper based on the Coanda effect of double jets. Firstly, a 3-D physical model of the double-nozzle air spray gun was built in Solidworks, in which unstructured grids were generated for the computational domain by ICEM.

Coil coatings containing both traditional and NIR pigments are considered for the assessment of their thermal behaviour. The same painted system produc

In this paper, we design a kind of negative pressure vacuum recovery hood, arranged at the front of the spray gun nozzle by CFD simulation; this addresses the paint mist pollution problem of the robot spraying on the outer plate of the ship, and the nozzle is arranged at the center of the recovery hood. Three vacuum recovery hood schemes are designed as follows: Scheme A, a hemispherical recovery hood with a diameter of 1.2 m; Scheme B, with a diameter of 1.6 m; Scheme C, with a diameter of 2.0 m. The recovery vacuum suction holes of the three recovery hoods are arranged differently. Firstly,

Abstract Experimental sprays were applied to single-tree plots in a randomized block design consisting of 2 replicates of ‘Golden Delicious’ and 2 replicates of ‘Yorking.’ Treated single trees were separated by others not sprayed with test insecticides. Trees were 8 years old and planted 20 x 30 ft apart. NTN-33893 and Carzol/Cygon were applied dilute to run-off with a pressure hand gun at approximately 4.1 gal per tree. The airblast treatment of NTN was applied with a Myers Mity Mist sprayer calibrated to deliver 75 gal/acre at 2.0 mph for a complete spray. The NTN 5% RTU treatment was applie

Until now there has been little uniformity in the approach of odour nuisance problems in Flanders. A switch to a standardised and scientifically underpinned approach is essential and is currently in full development. This paper mainly discusses the results of five year research on odour concentration standard developments in Flanders, executed in the period 1996-2000. The research was focused on five pilot sectors: pig farms, slaughterhouses, paint spray installations, sewage treatment plants and textile plants. The general approach of the method to determine the dose-response relation was fou

Powder spray coating was used for many applications such as paint decoration and protection against corrosive environments. The electrostatic spray method is used to lower the manufacturing cost and the environmental effect during the production process. It is done by electrostatic device and spray gun to create a layer on the substrate to play a protective role. Different dry powders were mixed to form a composite mixture consisted of Al2O3 and SiC or ZrSiO4 with Al powder as a binder. The powders mixture was deposited by electrostatic spray technique with a high voltage of 15 kV on a low car

Sticky traps are commonly used for monitoring insects in studies of their ecology (Southwood 1966) and in programs to manage their numbers (Flint and van den Bosch 1981). These traps may intercept flying insects or may visually attract insects over a distance (Southwood 1966). The relative sensitivity of an insect eye to different wavelengths of light may differ among species (Wigglesworth 1972) and therefore color can affect the quality and magnitude of trap catches (Prokopy and Owens 1983; Southwood 1966). The effect of color on trap catches therefore is often the first step in evaluating tr

Abstract A salt spray test was used to evaluate the corrosion resistance of pickling high-strength steel JSH440W to phosphating film on its surface, and scanning electron microscope (SEM) and energy dispersive spectrometer (EDS) were used to analyze the micro-morphology and element content of the surface defects area of the sample after salt spray test. The results show that the enrichment of Si, Mn, and O elements on the surface of pickling high-strength steel JSH440W badly influences the film-forming performance of phosphating film.

A lot of individual research on materials and methods suitable for the color of the paint layer has been conducted in the conservation of existing painted sculptures. However, there was no guidance standard for conservation treatment and repainting of painted sculptures, and an evaluation method for objective conservation management was required as deterioration continued in the outdoors. Therefore, in this study, the conservation treatment effect was confirmed by comparing and evaluating the physical properties of the original paint and the replacement paint by citing two cases.

A methodology for simulating drop transport and deposition in air-spray, paint-application processes is presented. Simulation of the complex physical phenomena involved is made possible through a number of key assumptions based on measurements of typical air paint sprays. The significant advance is the inclusion of the direct effects of turbulent air velocity fluctuations on the trajectories of paint drops via a stochastic separated flow approach. The model accurately predicts the mean air velocity field, paint transfer efficiency, and drop transfer efficiency. Owing to increased inertia, the

An efficient and simple method for preparing bonded metallic powder coating is in high demand in the paint manufacturing and application industries. The bonding purpose is to keep the mass percentage of metallic pigment consistent between the original and recycled coating powder, which aims at solving the problem of recyclability. One possible method capable of realizing this goal is using the binder to cohere metallic pigment with base particles through a cold bonding method. Through this approach, the pre-curing and high-reject-rate problems generally present in thermal bonding can be comple

In the process of painting the surface of injection products, the spray trajectory and speed are very important and have a very important effect on productivity and quality. However, since it is very difficult to standardize and quantify each product, it was difficult to apply automation to the painting process, so there were many cases where people directly operated it. Recently, with the development of robot technology, many manufacturing processes performed by humans are being replaced.
