you need know powder coating

Powder coating by special resin, pigment and filler, curing agent and other additives, 

mixed in certain proportion and through hot extrusion and crushing and screening processes 

of preparation. They are stored at room temperature, stable, electrostatic spraying or 

fluidized bed dip coating, and then heated to bake melting and curing, so that the 

formation of a smooth and bright permanent coating, to achieve the purpose of decoration 

and corrosion protection. Relatively easy to form a thick coating with a smooth, non 

textured surface, which is not easy to form a smooth film. As the film thickness decreases, 

the film becomes more and more orange peel due to particle size and glass transition 

temperature (TG), and the texture of the powder. In smaller operations, the cost of the 

powder coating will be higher than that of the paint.

Fine particles of powder coating in 

easy accumulation change the site of airflow direction in the coating device and spray head 

or in the pipeline, when accumulated to a certain degree the state of aggregation spray out 

attachment is painted above, baking does not melt and become diameter for 0.5-3 degree of 

particles attached in the spraying chamber wall and recycling equipment gelatinizer: 

coating process due to pigment produced condensates: part of the resin curing reaction gel 

particles in the melt mixing process in manufacturing, these particles will form a coating 

on the particles. In the construction of electrostatic spraying, the problem of 

environmental dust should be paid enough attention. Dust from the air, peeling off the 

operating personnel work tape bag recycling equipment on the fiber and curing equipment, 

the dust in electrostatic powder spraying process will cause film pollution and particles.

In the use of the powder coating process, should pay attention away from the fire source, 

to avoid direct sunlight should be well ventilated, temperature in less than 35 DEG C 

places; avoid storage in susceptible to water, organic solvent, oil and other materials 

contaminated sites; paints with not optional dew in the air, shall from time to time 

stamped or turn to close the bag to prevent debris mixed; avoid skin long-term contact, 

attached to skin powder apply soapy water rinse clean, do not use solvents. The equipment 

used for coating operation must be in good grounding to eliminate static electricity.
