Calcined kaolin is a kind of kaolin product after high temperature treatment, which has the characteristics of high temperature stability, chemical stability and high mechanical strength and is widely used in many industrial fields. The following are the use methods and application fields of calcined kaolin:

I. Method of use

(1) ultra-fine grinding

Calcined kaolin can be ultrafine ground by vertical roller mill to obtain products with finer particle size and larger specific surface area, thus improving its adsorption and reactivity.

(2) as filler or additive

Calcined kaolin is often used as filler or additive in papermaking, coatings, plastics, rubber and other industries to improve the performance of products and reduce costs.

(3) Ceramics and refractories

Calcined kaolin can be used to make ceramic blanks or as additives to improve the molding stability, sintering performance and mechanical strength of ceramics. It is also used to make refractories, acid and alkali resistant materials and wear resistant materials.

(4) Casting materials

In the casting process, calcined kaolin can be used as thickener, molding agent and anti-cracking agent to improve the surface quality and forming stability of castings.

(5) Rubber and plastic industry

Calcined kaolin can be used in rubber products to reinforce and improve the production process and mechanical properties of products.

II. Application areas

(1) Paper industry

Calcined kaolin is mainly used as filler and coating pigment in papermaking to improve the whiteness, smoothness and printing adaptability of paper.

(2) coating industry

As a constitutional pigment, calcined kaolin can improve the leveling, adhesion and storage stability of coatings.

(3) Ceramic industry

Calcined kaolin is an important raw material for manufacturing ceramics, which can improve the formability and sintering quality of ceramics.

(4) Building materials

Calcined kaolin can be used to make refractories, acid and alkali resistant materials and wear resistant materials, and is suitable for high temperature environment.

(5) High temperature equipment

In the manufacture of high-temperature equipment such as solar energy and nuclear energy, calcined kaolin is used in key components such as furnace, furnace lining and coating.

(6) Rubber and plastic industry

Calcined kaolin can be used in rubber and plastic products as filler to enhance the properties of materials.

(7) Electronics and catalysts

Calcined kaolin is also used in electronics, environmental protection, cosmetics, catalysts and other fields.

Through the above methods and application fields, calcined kaolin can give full play to its performance advantages and meet the needs of different industries.
