Coating knowledge: advantages of glass flake coating

Core tip: glass flake coating (resin lining technology) was first developed in the United States Owens Corning introduced a resin lining material with glass scales in the mid-1950s It is reported that this is a kind of excellent lining material suitable for ship hull, chemical storage tank, tower and tank body of chemical plant This material can withstand the penetration of environmental medium and help to extend the lining life At the same time, Japan began to study an epoxy vinyl ester resin (VE) with better performance than general unsaturated polyester resin (up) 1967, Fuji Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: glass flake coating (resin lining technology) was first developed by the United States Owens Corning introduced a resin lining material with glass scales in the mid-1950s It is reported that this is a kind of excellent lining material suitable for ship hull, chemical storage tank, tower and tank body of chemical plant This material can withstand the penetration of environmental medium and help to extend the lining life At the same time, Japan began to study an epoxy vinyl ester resin (VE) with better performance than general unsaturated polyester resin (up) In 1967, Fuji resin company successfully developed ve glass flake coating, using the glass flake originally created by Japan's Panzhihua company, which was successfully applied to the flue gas desulfurization device in the form of lining with high viscosity construction, and began to be practical The technology is also exported overseas In the early 1980s, the flue gas desulfurization unit of Guixi Smelter in China was the ve glass flake lining provided by the company In 1972, Japan Mitsubishi resin company and Japan polymer chemical company introduced Ceilcote technology Toyo rubber industry company imported heill technology and started large-scale R & D and application On the one hand, as the glass flake coating (lining) is a high thickness film coating with millimeter as the unit, it is very suitable for harsh corrosion environment, such as marine salt corrosion area, various chemical tanks, marine buildings, coastal concrete buildings, etc.; on the other hand, Japan is surrounded by the sea, and its special geographical environment forces it to pay more attention to long-term and effective glass flake coating For the evaluation of resin lined film technology, Japan is currently in the leading position In 1974, Japan established the "Research Institute of flake lining technology" by resin lining Industry Association Through the theory of infiltration and diffusion, the research and development of resin flake lining technology and flake lining technology were actively carried out, and the application scope of glass flake coating was expanded Glass scale anti-corrosion is a new anti-corrosion technology Its working principle is to arrange glass scales in the resin in a laminated state, effectively increase the penetration distance of corrosive medium diffusion, and reduce the probability of corrosive medium contacting the protected matrix Glass flake anticorrosion is mostly realized in the form of glass flake coating There are many advantages of glass flake coating After combining the advantages of glass flake and thermosetting resin, the glass flake shows much higher working characteristics than ordinary glass and resin, especially in the anti permeability and other aspects, it has a significant improvement The following are some advantages of glass flake coating compared with ordinary glass 1 The resistance of glass flake coating to various media is much higher than that of glass fiber reinforced plastics, such as chemical media, gas, steam and other media, which are difficult to penetrate the glass flake coating, and the coating made of glass flake coating also rarely shows the phenomenon of water vapor diffusion The reason why the glass flake coating has this characteristic is that the glass flakes are arranged in the resin layer by layer 2 The shrinkage of glass flake coating after curing is very low, so the stress between the coating and the bonding surface is small, and it is not easy to fall off due to the stress 3 The thermal expansion coefficient of glass flake itself is small, it can adapt to high temperature working environment, and has good thermal shock resistance 4 The chemical strength of glass flake coating is lower than that of FRP, but it does not affect the wear resistance of glass flake When the glass flake coating is subjected to friction, even if the damage occurs, it is only limited to local parts, and rarely affects the whole glass flake coating 5 The construction process of glass flake coating has good performance and low construction difficulty The workers can finish the application of glass flake coating by hand Other construction processes such as spraying, coating and plastering are also applicable to glass flake coating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
