Background technology
Powdery paints is a kind of novel to be free of 100% solid powdery coating of solvent.With without solvent, pollution-free, section
It saves the energy and resource, reduce labor intensity the features such as high with coating machinery intensity.It has three categories：Thermoplastic powder coating
（PE）, thermosetting powder coating, building powder paint.Coating is by specialty resins, color stuffing, curing agent and other auxiliary agents, with one
Fixed ratio mixing, then be prepared by hot extrusion and the techniques such as pulverize and sieve.They store and stablize, through quiet at normal temperatures
Electrospray, friction spraying（Heat curing process）Or fluidized bed dipping（Thermoplastic method）, baking melting and solidification is reheated, makes to be formed smooth
Bright permanent film reaches decoration and etch-proof purpose.Its characteristic has：1, the product is free of toxicity, without solvent and
Without the virose substance that volatilizees, therefore the problem of the public hazards such as discharge without poisoning, without fire, without " three wastes ", country is complied fully with
The requirement of environmental law.2, utilization rate of raw materials is high, and the powder of the powder supplies quotient production of some famous brand names crosses the powder of spray
Recoverable, highest utilization rate even can be up to 99% or more.3, after coated article pre-treatment, one-off construction is not necessarily to bottom
It applies, you can obtain the film of adequate thickness, easily realize automation mechanized operation, production efficiency is high, can reduce cost.4, coating it is fine and close,
Adhesive force, impact strength and toughness are good, and corner coverage is high, have excellent resistance to corrosive chemicals can and it is electrical absolutely
Edge performance.5, powdery paints storage, transportation safety and conveniently.However as the development of society, requirement of the people for coating
It is higher and higher, the intensity, stability, hydrophobic performance etc. of traditional powder coating made higher requirement.
