Technical question 4. Why does a batch of white powder-coated products have color difference?

Today, I will answer the question of why a batch of white powder coating products will have color difference.


There are several reasons that affect the difference of white spray color in the same batch:


1. Material.

The stability of the material. The properties of commonly used materials will be relatively stable, but due to the influence of humidity or large temperature differences, the stability of the materials will change, which will cause the same batch of white color.


2. Spraying skills.

The effect of powder spraying is caused by the thickness of powder spraying. According to different products, the greater the product heterogeneity, the easier it is to have color difference in the same batch of products.


3. Baking temperature.

In order to ensure the firmness of the powder and the water cup, the powder sprayed product will be baked at a high temperature, and the control of the temperature is also very important. The color of baking during the preheating process of the oven will be significantly different from the white baked when the temperature in the oven continues to rise.

How to eliminate chromatic aberration? Also proceed according to the above points


First choose toner materials that are well preserved and of good quality. At the same time, fully automatic spraying is used as much as possible in spraying to ensure that the spraying angle and thickness of each product are consistent. The last is to strictly control the temperature in the furnace, and control the temperature in the furnace at ±5°C.


Make sure to do the above three points. Regardless of the number of finished products, the white spray color difference on the surface of the water cup will be significantly reduced, and the color difference can be eliminated when it is controlled properly.
