Description

technical field [0001] The invention relates to the technical field of plastic processing, more specifically, it relates to a processing technology for plastic powder. Background technique [0002] Plastic powder is the product of further pulverization of plastic particles. Plastic particles can only be used to make various plastic products, while ultra-fine plastic powder with uniform particle size can not only be melted and granulated into plastic particles to make plastic products, but also Overcoming the shortcomings of other powder particles, it can be applied to various coatings, which can improve the uniformity of the coating surface, and the superiority of light transmission and light reflection performance. Therefore, ultrafine plastic powder particles are more and more widely used in subsequent applications. [0003] The Chinese patent document with the application number: 201911126412.9 discloses a thermoplastic powder and its processing technology, which mainly u...
