powder coating production

our plant the production of powder coating solvent, nor any volatile toxic substances, in 

full compliance with the requirements of the national environmental law. Coating density, 

adhesion, impact strength and toughness are good, the edge angle coverage rate is high, has 

excellent chemical resistance and electrical insulation properties. Paint storage, 

transportation safety and convenience. Before being treated, the coating can get enough 

thickness of coating film, easy to realize automatic operation, high production efficiency 

and lower cost.

The fabrication process of the powder coating is mainly by special pigments and fillers, curing agent, special resin and other additives, proportional mixing, and through crushing sieve, a hot extrusion process for preparation of. The electrostatic spray, sprayed friction (thermoset) method or fluidized bed dipping (thermoplastic), re heating melting and solidification, forming smooth bright permanent film, achieve purpose of decoration and corrosion. Use should pay attention to the following points: engineering should avoid long-term exposure of powder coatings and skin; engineering in floating dust concentration to control the safe concentration below the critical point, avoid fire and explosion; away from fire, avoid direct sunlight; coating after use should be at any time stamped or turn to close the bag to prevent debris mixed.

Thermosetting coating systems, polymers are generally low molecular weight monomer, melt flow in the heat, while the chemical reaction of curing or crosslinking. After the reaction is complete, can not be re melted into a plastic state as a thermoplastic material. Crosslinking reaction occurs between the resin and the curing agent. To make the film smooth and continuous, before 

curing polymer must be continuous and smooth flow into the membrane. The change of powder 

formula is to find the equilibrium point between the softening temperature and the melting 

viscosity or the melting property and the speed of the crosslinking. Similar to the solvent 

based paint, thermosetting powder coatings can be designed to produce high and low gloss 

decorative paint, aluminum, copper, copper or metal color, sand lines, vertical lines, etc..
