General knowledge of coating: the influence of different types of titanium dioxide on powder coating

Core tip: titanium dioxide is a white pigment commonly used in white polyester epoxy powder coating Different types of titanium dioxide a0101, r940, r902, r244, R930 and r706 were compared by choosing the common white polyester epoxy powder coating formulation 　　 Different types of titanium dioxide have different chemical compositions and properties due to different manufacturing processes, crystal forms and surface treatment methods, which have different effects on the chemical reaction activity and dispersion of polyester epoxy powder coatings, and have obvious effects on the gelation time and melting level fluidity of powder coatings 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 Home of coatings: titanium dioxide is a white pigment commonly used in white polyester epoxy powder coatings Different types of titanium dioxide a0101, r940, r902, r244, R930 and r706 were compared by choosing the common white polyester epoxy powder coating formulation Different types of titanium dioxide have different chemical compositions and properties due to different manufacturing processes, crystal forms and surface treatment methods, which have different effects on the chemical reaction activity and dispersion of polyester epoxy powder coatings, on the gelation time and melting level fluidity of powder coatings, and on the coating film The fluidity, luster, chromatic aberration and impact resistance of are also affected The powder coating prepared by anatase type titanium dioxide (a0101) is more active than that prepared by rutile type titanium dioxide (R), with short gelatinization time, low melting level fluidity, poor film flatness and low gloss There are also obvious differences in technical indexes between rutile titanium dioxide Therefore, according to the requirements of powder coating performance, it is very important to select titanium dioxide varieties that can meet the requirements of powder coating and coating performance In the matt polyester epoxy powder coating, anatase titanium dioxide is easier to discolor or yellowing the coating than rutile titanium dioxide, so rutile titanium dioxide is the best choice for this coating system 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,
