Problems

 

 Analysis

 

Solution

 

Pinhole

1. Spraying air pressure is too low
2. A large amount of paint
3. A thicker film.

1.   Adjustment of air pressure

2. Control the film thickness
3.To increase the dissolution power of thin material

Sagging

1. A large amount of paint
2.Construction of the viscosity is too low
3. Dilute volatile material slowly
4.Environmental emperature at the end of the low one

1.Adjustment; spraying conditions
2. For quick drying of thin materials 

Flooding

1. A large amount of paint
2. Construction of the viscosity is too low
3. Ambient temperature lower one.

1.Adjustment; spraying conditions
2. For quick drying of thin materials

Orange peel

1. Out of a small amount of paint
2. GUN far away from
3. High temperature
4. Dilute volatile material fast one.

1.Adjustment; spraying conditions
2. For slow drying thinner

Exposed at the end of one.

1. Construction of the viscosity is too low
2. Film thickness of

 

1. Improve the construction viscosity
2. Increase the film thickness

Pale one.

1.Air humidity
2. A high temperature.

1.Plus anti-white-agent

Bite at the end of one.

1.Construction of the viscosity is too low
2. Dilute power is too strong a material dissolved.

1. Improve the construction viscosity
2. For dissolving power is low for thin material

A high luster.

1.Spraying high viscosity
2. Film thickness
3. Dilute volatile material slowly
4. A large amount of paint
5. A high-gloss paint.

1.Reduce the spraying viscosity
2. Control the film thickness
3. Adjustment of spray
4. Injecting matting agent

Particle

1. Substrates untreated clean
2. Paints a particle
3. Air impurities

1. Deal with the substrate
2. With the appropriate filter, paint
3. Air Filter

Diaoqi

1. Substrates untreated clean
2. Construction of the viscosity is too high
3. Dilute power is too weak material dissolved
4. Paint itself is a poor attachment.

1. Deal with the substrate
2. Adjusting the construction viscosity
3. For use of highly dilute dissolved material
4. Adjustment of coating formulations
