美国麦奇克激光粒度仪的应用—粉末涂料和微粒的尺寸测量
Powder coatings—substances that are protective, decorative, or both—are formed by the application of a coatingpowder to a substrate and fusing the coating into a continuous film by the application of heat or radiant energy. Coatingpowders are finely divided particles of organic polymer that generally contain pigments, fillers, and additives thatremain finely divided during storage under suitable conditions. In contrast to liquid coatings, which may contain volatileorganic solvents, powder coatings can achieve the same or better characteristics of quality, durability, and corrosionresistance.
