Reasons and solutions for particle formation in mobile phone spray coating:

Reason: The homework site is not clean, and dust is mixed into the paint; After mixing the paint for too long, copolymer particles have formed between the paint and curing agent; The oil output of the spray gun is too small, and the air pressure is too high, resulting in poor atomization of the paint or the spray gun being too close to the object surface.

Solution: Clean the paint booth and cover the paint bucket; Paint should be well prepared and not left for too long; Adjust the spray gun to its optimal working condition, and ensure that the muzzle is 20-50CM away from the object surface.
