Common knowledge of coating: analysis of four methods to improve the powder loading rate of powder coating

The key points are as follows: analysis of four methods to improve the powder loading rate of powder coating: 1 To control the particle size distribution of the powder, the narrower the better: to control the particle size of the powder reasonably (it is difficult), in our actual production, only the speed of the main and secondary grinding of ACM can be adjusted The powder size of 40-50um is suitable, the narrower the distribution is, the better 2 Improve the resin content: increase the resin content, reduce the filler content, select the resin with good electrical performance, epoxy is better for powder application, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder (grind epoxy and polyester into powder spray plate separately), and the spray from the friction spray gun is smooth 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 Coating home news: four methods to improve the powder coating powder rate are analyzed: 1 Control the powder particle size distribution, the narrower the better: reasonably control the powder particle size (relatively difficult), in our actual production, only adjust the speed of the main and secondary grinding of ACM The powder size of 40-50um is suitable, the narrower the distribution is, the better 2 Improve the resin content: increase the resin content, reduce the filler content, select the resin with good electrical performance, epoxy is better for powder application, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder (separately grind epoxy and polyester into powder spray plate), the spray level of friction spray gun is obviously better than that of electrostatic gun, and the friction gun can spray thick coating, and the coating has no disadvantages of high-pressure gun Such as big orange peel 3 Reasonable selection of fillers: fineness and dispersion of fillers are closely related to powder loading The precipitated powder is higher than the general superfine heavy barium, and the barium sulfate is better than the calcium carbonate 4 Add electric assistant: add electric assistant in the formula (mechanism: it can make powder particles carry more electric charge There is a strong electric field in the area from the high-voltage electrostatic spray gun to the workpiece, and the air is ionized to produce hundreds of millions of ions When the powder particles of the electrostatics pass through this area, they are polarized, which can catch more negative ions and carry more charges Due to the weak power line of Faraday effect, the powder particles with more charges can reach the surface of the workpiece by their own force, so as to improve the powder loading of these parts 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,
