Prevention methods |
⑴The paint is too thick The paint liquid is too thick, it is easy to wrinkle when used, and the hiding power is poor after dilution |
Newly-opened barrels of paint should generally be adjusted with diluent before use. When the hiding power is poor, you can open another bucket of paint and use them together |
⑵ Hanging Sometimes the paint in the newly opened barrel is too thin, the paint pigment is too small, and the paint sags if it is thickened |
It can be mixed with paints of the same type and color, and used after stirring evenly. The coating should not be too thick |
⑶ not dry, stick back Improper use of paint, improper heat refining, improper resin ratio or insufficient drier, etc. |
Poor paint should be replaced. Drying is slow due to insufficient amount of drier, which can be adjusted by adding drier. |
⑷ Particle protrusions The paint production control is not strict, the pigment grinding is not enough or the container is not clean |
When using, the paint liquid should be stirred evenly and filtered through a fine sieve |
⑸ “orange peel” and wrinkles Improper polymerization of oil in the coating, improper solvent matching, excessive coating viscosity, etc. |
The paint quality is poor and should be replaced. Do a coating test before construction to adjust the viscosity |
⑹ Loss of light The solvent quality in the paint is poor, the film-forming material is too small, and the thinner is too much, which causes the paint film surface to dry too quickly and lose its gloss |
It can be mixed with the same kind of paint to adjust to the appropriate viscosity, or add part of the varnish to improve the gloss |
⑺ turns white The weather is humid, and the nitro paint is easy to whiten, or the thinner ratio is improper |
Preheat the workpiece at low temperature first, or add 10%--20% moisture-proof agent |
⑻ No bottom cover Insufficient pigment content in paint, too much diluent in barrel |
Open an extra bucket of paint of the same variety and color, match each other, adjust the viscosity, and fine-tune the construction |
⑼ Color mismatch Paint color does not conform to standard. Sometimes the color is very different, even if it is fully stirred, it does not solve the problem |
Can be redeployed with similar paints |
