Description

Technical Field

[0002] Plastic powder, plastic ultrafine powder, resin powder Plastic is a synthetic polymer compound, also known as polymer or macromolecule, also commonly known as plastic or resin, which can change shape freely. It is a material made by synthesizing or condensing monomer raw materials, composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Plastics are generally divided into two types: thermoplastic and thermosetting. Thermoplastic means that the material will soften after heating, and will harden into the shape we need after cooling, and can be softened and formed repeatedly. Thermosetting will condense into a certain shape after heating. Reheating to a certain degree will destroy the internal structure of the molecule, and one or more elements will be released and separated to become other synthetic bodies.

[0003] In the production process of plastic powder, raw materials are generally added manually one by one. This method not only leads to a large consumption of manpower, but also is greatly affected by the working time of people, which directly affects the production efficiency of plastic powder. At the same time, when multiple raw materials are mixed, a large amount of powder dust will be generated, resulting in a waste of plastic powder raw materials and damage to the health of workers. Therefore, it is urgent to design a mixing equipment for plastic powder to solve the above problems. Utility Model Content
