Uses -

1. Paper industry: kaolin is used as filler and paper coating in the paper industry to improve the gloss of paper, fill the gaps between paper fibers, improve opacity, etc. It can also improve the permeability and inclusiveness of ink and the appearance of paper. It can also improve the permeability and inclusiveness of paper to ink and the appearance of paper.

2. Ceramic industry: Kaolin is one of the main raw materials for manufacturing ceramics, which can increase the content of Al2O3 in ceramics and improve the sintering strength and stability of ceramics. It also has plasticity, bonding, suspension and combining ability, which gives porcelain clay and porcelain glaze good formability.

3. Paint pigment: Kaolin is used as filler of paint and lacquer because of its white color, low price, good mobility, stable chemical properties, and large surface cation exchange, which improves the paintability, storage stability, moisture absorption and impact resistance of the coating.

4. Refractory materials: kaolin has good refractory properties, often used to produce refractory materials, the products can withstand the load at high temperatures without deformation.

5. Rubber industry: Kaolin can be used as filler and reinforcing agent in rubber industry to improve the strength, hardness and abrasion resistance of rubber products, as well as to improve its processing and physical properties.

6. Plastics: kaolin can be added into plastics as reinforcing agent to improve the compressive strength, modulus of elasticity and toughness and other physical and mechanical properties of plastics.

7 Environmental protection field: kaolin can be used in heavy metal sewage treatment, secondary resource utilization and degraded oil treatment.

8 New energy: with kaolin and sodium stearate as raw materials, a new type of kaolin/sodium stearate phase change heat storage material can be prepared, which is suitable for the heat storage system of solar thermal power station.

9 New materials: kaolin can be used to prepare molecular sieves, nanomaterials, kaolinite organic intercalation materials, glass fibers and so on.

10.Biomedicine: In the field of biomedicine, kaolin can be used in hemostatic materials, drug carriers, antimicrobial materials and so on.
