In the production of silica gel products, many people will confuse the color matching of color mixing box, thinking that it is the same. In fact, it is the color matching of color mixing box. Color mixing refers to the color that is the closest to the target color based on the original color, while color matching refers to the color composition of the target color according to the color master proportion to achieve the closest target color. After matching, the formula is recorded for next use.

The color mixing operation of silicone rubber products is based on the color matching operation, which is to adjust the original formula, so as to achieve the desired goal. The method is basically the same, except that the color matching needs to draw up a formula from scratch and adjust the color, while the color mixing is based on the original formula to add or subtract color masterbatch and weight, so that it is closest to the target color and summarize and record the formula.

The color matching method of rubber products is the same as that of silica gel products. The color masterbatch is analyzed according to the target color first. Which color is composed? When choosing color masterbatch according to this, what is the weight of each color masterbatch? Write a preliminary color formula according to the analysis results, and make the first color blending according to the formula. After the first color blending, it is necessary to match the color with the target color, and analyze the color difference between the actual color and the target color. If the color difference between the actual color and the target color is too large, it is necessary to continue blending according to the color difference direction and referring to the color masterbatch matching relationship in the table above, and record the color masterbatch and weight added for each blending, The formula of color matching shall be summarized and recorded until the actual color is very close to the target color.
