Powder coating is different from the general coating, which is the state of the fine
powder. Because of no use of solvent, it is called a powder coating. The utility model has
the advantages of no solvent, no pollution, saving energy and resources, reducing the labor
intensity and the mechanical strength of the coating film. It has two major categories:
thermoplastic coating (PE) and thermosetting coating. A special coating resin, pigments
and fillers, curing agent and other additives, mixed in a certain ratio by hot extrusion,
and crushing and sieving process prepared. The storage stability at room temperature, the
friction electrostatic spraying, spraying (thermosetting method), or fluidized bed dipping
(thermoplastic method), then heating melting and solidification, to form a flat permanent
film light, to achieve the purpose of decoration and corrosion.
Powder coating is free of solvents, 100% solid powder coating. There are a lot of places to be noticed when using. In order to make the special function of powder coating and extend the service life of the coating film, the surface of the coated material is mainly used to deal with the appearance before the appearance. Coating, the coating must be completely grounded in order to add powder coating spray power. The great disadvantage appearance of the object to be coated,
should be scraping conductive putty, to ensure the smooth and smooth film.
In order to make the characteristics of powder coating to fully exert and prolong the service life of the coating, the surface of the coated material is first strictly carried out before the
surface treatment, spraying, the coating must be completely grounded in order to increase
the efficiency of powder coating spray. The larger the surface defects of the object to be
coated, should be scraping conductive putty, to ensure smooth film and smooth feeling,
after spraying for object detection and heat curing, curing conditions to index powder
technology products for the quasi but must fully guarantee the curing temperature and time,
avoid quality accidents caused by insufficient curing. Check immediately after spraying, if
found defects should be timely treatment, if after curing defects are found, the only local
small range without affecting, the coated surface decoration, can use the same color powder
and acetone diluted to repair, if the scope is large and affects the surface quality, use
sandpaper, again or off remove the paint coating agent, re Suo powder.
