Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: 1 Polishing powder: polishing powder is usually composed of alumina, silicon oxide, zirconia, ceria and other components Different materials have different hardness and chemical properties in water, so the use occasions are different The Mohs hardness of alumina and zirconia is 9, that of ceria and silicon oxide is 7, and that of iron oxide is lower Ceria and silicate glass have high chemical activity and similar hardness, so they are widely used in glass polishing 2、 The basic requirements for polishing powder are: (1) the particle size of the powder is uniform and within the allowable range; (2) it has high purity and does not contain machinery Impurities; (3) good dispersion to ensure the uniformity and efficiency of the processing process, and appropriate dispersant can be added to improve the suspension rate; (4) the powder particles have a certain lattice shape, forming sharp edges and corners when they are broken, so as to improve the polishing efficiency; (5) proper hardness and density, and good wettability and suspension of water, because the polishing powder needs to be mixed with water with more particle size The larger the grinding force is, the more suitable it is for hard materials It should be noted that there is a distribution problem of the particle size of all polishing powders The size of the average particle size or median diameter D50 only determines the speed of polishing, while the maximum particle size Dmax determines the precision of polishing Therefore, in order to get high precision, it is necessary to control the largest particle of polishing powder The reason why ordinary polishing powder has scratches is that it has large particles Therefore, nano polishing (vk-l300f) with narrow particle size distribution is generally selected The concentration of slurry determines the polishing speed The higher the concentration, the higher the polishing speed When using small particle polishing powder, the slurry concentration should be properly adjusted to obtain the appropriate fluidity It is generally recommended to use a soft polishing die at 7-10% 3 It should be pointed out that ceria powder is added to many polyurethane polishing plates The maximum particle size of these polishing powders also determines the final polishing accuracy Generally, it is better to use a polishing die without polishing powder 4、 Index 1, particle size of polishing powder: the particle size and uniformity determine the polishing speed and precision The number of sieving mesh can control the relative particle size of the powder, and the average particle size determines the overall level of the particle size of polishing powder 2 Mohs hardness of powder: the powder with relatively large hardness has a faster cutting effect, and the addition of some grinding aids can also improve the cutting effect; different application areas will have great differences, including their own processing technology 3 Suspension property of powder: good polishing powder should have good suspension property The shape and particle size of powder have certain influence on suspension property The suspension property of polishing powder with nano particle size is relatively better, so nano polishing powder is generally selected for fine polishing 4 Crystal form of powder: the crystal form of powder is a single crystal particle gathered together, which determines the machinability, wear resistance and fluidity of powder The single crystal particles agglomerated with powder are separated (broken) in the polishing process, which makes the machinability and wear resistance decrease gradually The polishing powder with spherical particles has good machinability, wear resistance and fluidity 5、 Subdivision of polishing scope: as a fine polishing material, the most widely used polishing powders in the market are mainly alumina polishing powder, ceria polishing powder, silicon oxide polishing powder, etc 1 Aluminum oxide polishing powder: aluminum oxide polishing powder (vk-l300f) is generally used for marble polishing, metal aluminum polishing, metal stainless steel polishing, metallographic (acrylic) polishing, PCB PCB PCB polishing, paint polishing, resin polishing, jade polishing, particle size is generally distributed between 0.2-0.5um according to the requirements 2 Silicon dioxide polishing powder: it is generally used for polishing artificial crystals, gemstones, or metal products to repair a small number of defects after polishing Its particle size is generally distributed in 0.3-1um3 Ceria polishing powder or polishing liquid (vk-ce02w): used for polishing lens, television picture tube, glasses, wafer, optical element, optical fiber, art glass, electronic glass, flat glass, etc The primary particle size is generally 20-30nm, and the secondary particle size is generally 0.2um 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,
