Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder crushing devices, in particular to a plastic powder crushing device. Background Art

[0002] Powder coating is a formula material with synthetic resin as base material, pigment and filler. It is a new decorative material that has developed rapidly in recent years. It has the characteristics of energy saving, low pollution, high efficiency and high performance. As a solvent-free coating, it has high coating efficiency and good corrosion resistance. It can form a film in one time and is convenient to store and transport. It is becoming increasingly popular. Thermoplastic powder coating is obtained by dry mixing or melt mixing of thermoplastic resin, pigment, filler, plasticizer and stabilizer, and then crushing, screening and grading.
