The main component of washed kaolin is aluminum silicate,

The main component of washed kaolin is aluminum silicate, which also contains a small amount of iron, calcium, potassium, sodium and other minerals, of which the content of silicon and aluminum is relatively high, accounting for almost 90% of the entire composition.
Physical properties Washed kaolin has good whiteness, brightness, uniform and fine particle structure and chemical stability. Its particle refining reaches less than 1 micron, the internal porosity is less than 30%, the specific surface area is higher than 200 square meters per gram, and there is no needle-like or scaly material, and the content of impurities such as talc, mica, quartz is very low.
Application field

Ceramic industry: Washed kaolin is an important ceramic raw material, which can be used as a whitening agent and leveling agent to improve the quality and gloss of ceramics.
Building materials industry: In the building materials industry, washed kaolin can be used as fillers and white pigments.
Rubber industry: washed kaolin can be used as enhancers and fillers.

4, plastic industry: washed kaolin can be used as a filler, so that plastic products have better uniformity and softness.

Cosmetics industry: Washed kaolin is an important cosmetic raw material, which can be used as a softening agent such as foundation and eye shadow.

In short, washed kaolin is a non-metallic mineral material with wide application value and has very important applications in various fields.
The effective application of washed kaolin in the field of coating can replace the expensive titanium dioxide additives in the past, reduce the production cost of coating industry, and is an ideal raw material. White amino paint prepared by washing kaolin as pigment filler in coating industry. The actual properties of exterior wall latex paint meet the relevant standards of the coating industry, and provide a reliable basis for the production quality control of the coating industry, which helps to promote the stable and sustainable development of the coating industry.
