Description

Technical Field

[0001] The utility model relates to the technical field of discharging machines, in particular to a discharging machine for powder coating production. Background Art

[0002] Powder coating is completely different from general coating. It exists in the state of fine powder. Since no solvent is used, it is called powder coating. The main characteristics of powder coating are: harmless, efficient, resource-saving and environmentally friendly. It has two major categories: thermoplastic powder coating and thermosetting powder coating. Thermoplastic powder coating is composed of thermoplastic resin, pigment, filler, plasticizer and stabilizer. Thermoplastic powder coating includes: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose and polyester. Thermosetting powder coating is composed of thermosetting resin, curing agent, pigment, filler and additives. Thermosetting powder coating includes: epoxy resin, epoxy-polyester, polyester, polyurethane and acrylic resin.

[0003] There is a discharge step in the production process on the market. Most of the discharge is transported through a discharge pipe. However, when the discharge pipe is used for transportation for a long time, some parts of the discharge pipe are in direct contact with the air, resulting in residual paint on the tank wall. It is very inconvenient to clean the residual paint, and the long-term residue of these paints will affect the normal discharge of the paint. At the same time, the residual paint will also hinder the normal transportation of the paint, causing the paint transportation speed to become slower and slower. Utility Model Content
