Cause Analysis and Solution of Foaming in Fluorocarbon Paint Painting

During the construction of fluorocarbon paint, if improper operation is prone to blistering paint disease, what is the cause of blistering and how to solve it? The blistering of the paint film is a state in which a part of the paint film loses adhesion to the surface of the workpiece after the paint film is dried, and the spherical small bubbles with different diameters expand upward, containing liquid or gas inside, or a state of rupture.

Reason 1: The grease is not completely removed, but the metal surface is adhered to the metal surface.

Reason 2: When the fluorocarbon paint is sprayed on the exterior wall, the wall is damp, so it is eager to paint.

Reason three: When the top coat is applied to the primer that has not dried out, the volatile liquid inside is heated to expand and the paint film is arched.

Reason 4: The new paint film that has just been painted quickly approaches high temperature or is exposed to direct sunlight.

Reason five: the workpiece is not clean when rusting, rust bubbles are generated or some gas is diffused after baking.

Reason 6: The neutralization of the pickled workpiece is not complete, there is residual acid, and bubbles are generated after painting.

Reason 7: The air compressor and pipes contain moisture.
