I. Overview of washed kaolin resources in China

The distribution of washed kaolin in China is relatively wide, mainly concentrated in Jiangxi, Hubei, Guangxi, Guangdong, Fujian and other provinces. These areas not only have the advantage of kaolin resources reserves, but also have the corresponding technical level and processing capacity, making them an important base for China's washed kaolin industry.

China's kaolin resource reserves are close to 3.5 billion tons, which is in the forefront of the world. At the same time, China's kaolin is mainly used in ceramics, paper making and coating industries, of which ceramics, paper making and coating are the main downstream demand industries for kaolin. The growth of demand in these industries promotes the development of upstream kaolin exploration and mining industry, which in turn promotes the growth of kaolin production.

II. Application areas of washed kaolin

As a high-quality industrial raw material, washed kaolin has a wide range of applications.

Ceramic industry: washed kaolin is widely used in the ceramic industry, mainly used in the manufacture of high-grade ceramic products, such as tableware, vases, handcrafts and so on. Due to its high whiteness, bonding and good plasticity, washed kaolin can significantly improve the strength, toughness and wear resistance of the ceramic body, and enhance the glaze adhesion, creating high-grade ceramics with a more delicate texture.

Building materials industry: In the building materials industry, washed kaolin is used in the manufacture of gypsum board, cement products and molding materials. It has good thickening and tackifying properties, which can improve the strength of gypsum boards to make them fit the wall better, and increase the hardness and water resistance of cement products to improve the overall performance of building materials.

Coating field: In the field of coating, the application of washed kaolin is mainly reflected in the pigment filler.

It can fill in between the titanium dioxide particles, hinder the flocculation of titanium dioxide particles, effectively avoid the generation of light flocculation, thus promoting the effective performance of titanium dioxide's actual covering effect.

In practice, washed kaolin can replace 5-15% of titanium dioxide without adversely affecting the performance of coatings.

Other Industries

Washed kaolin is also widely used in rubber, plastics, paper making, cosmetics and other industries.

In the rubber and plastics industry, it can be used as a filler and reinforcing agent to improve the strength and durability of products.

In the paper industry, washed kaolin is used as filler and coating pigment to improve the gloss and whiteness of paper.

In the cosmetic industry, due to its good adsorption and stability, washed kaolin is used as a base material and filler for cosmetics.

To summarize, washed kaolin plays an important role in many industries, and its application fields cover ceramics, building materials, coatings, rubber, plastics, paper making and cosmetics. With the continuous progress of science and technology and the growing market demand, the application fields of washed kaolin will be further expanded.
