when you spray powder coating

Production process of powder coating is mainly composed of special filler, curing agent, 

special resin and other additives in the corresponding proportion, and through crushing and 

sieving, hot extrusion process preparation is prepared. The electrostatic spraying, 

spraying friction (thermosetting method) or fluidized bed dipping (thermoplastic method), 

then heating melting and solidification, forming a flat permanent film light, to achieve 

the purpose of decoration and corrosion. When in use should pay attention to the following 

points: the project should avoid prolonged contact with skin powder coating; to control in 

the following safety critical concentration the concentration of floating dust in the 

project, to avoid fire and explosion; away from fire, avoid direct sunlight; paint after 

use at any time stamped or turn tightly to prevent debris mixed.

In addition, should pay attention to in the use of powder coating, powder supply barrels, spraying room and recovery system should avoid different color powder pollution, so every time the color change must purge clean; in order to make the characteristics of powder coating can give 

full play to extend the service life of the coating and broken, first strictly surface 

pretreatment coated surface immediately after the inspection; dusting, 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 use paint remover to remove the coating, again to have larger Suo powder; surface 

defects should be coated, scraping conductive putty, to ensure smooth film and smooth 

feeling.

In the process of spraying powder coating, to have larger surface defects of the 

object to be coated, should be scraping conductive putty, to ensure smooth film and smooth 

feeling. After spraying, the object needs to be heated and solidified, and the curing 

condition is the technical index of the powder product. But it must fully guarantee the 

curing temperature and time. 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. The recovered powder must be filtered to 

remove the impurities, and then mix with the new powder.
