Powder coating storage, construction environment, loss of light and handling!

The storage of powder has a great influence on its quality

Powders of different varieties cannot be placed together so as not to contaminate each other paint online coatingol.

construction environment

Powder construction units have different environmental requirements, some are open-air or closed, and some are integrated with the production workshop

The correct powder application environment should be independent and equipped with powder recovery equipment

Loss of light phenomenon and treatment of powder

(1) If the powder exceeds the specified time and temperature in the oven, it is likely that the surface will lose its gloss

Due to the different heat energy required for different materials, the time in the furnace is different

(2) In order to reduce waste during construction, the recycled powder is added to the new powder and mixed for use, which often causes the surface of the workpiece to lose its luster

(3) The powder is agglomerated due to high temperature or excessive extrusion

(4) The powders of different manufacturers are mixed with each other, and the powder will lose its luster due to mutual interference
.
If you need powder from different manufacturers, you must clean up the powder supply barrel, spray gun, powder pipe and surrounding environment of the electrostatic generator, and then use another powder
.

(5) Generally, powder should not be stored for too long
.
If the time is too long, the gloss will change.
Generally, powders with higher gloss will be stored for too long, and some powders will lose their gloss after construction
.
Powders with low gloss, such as black matt, gray matt, etc.
, are likely to have corrugated sand patterns after being stored for a long time
.

(6) Transparent powder interferes with other powders.
As long as you have used transparent powder during construction, if you want to change other powders, you must clean up the gun, powder supply bucket and spray booth thoroughly
