Product introduction:

Kaolin is a non-metallic mineral, a kind of clay and clay rock dominated by kaolinite clay minerals. Because it is white and delicate, it is also called white cloud soil. It is named after Gaoling Village, Jingde Town, Jiangxi Province.

The pure kaolin is white, fine, soft and soft, with good plasticity and fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin has a wide range of uses. It is mainly used in papermaking, ceramics and refractory materials, followed by coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount is used in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, etc. Pesticides, textiles, petroleum, chemicals, building materials, national defense and other industrial sectors.

The role of kaolin in ceramics is to introduce Al2O3, which is conducive to the formation of mullite, and improves its chemical stability and sintering strength. During firing, kaolin decomposes to form mullite, which forms the main frame of green body strength, which can prevent the product from decomposing. Deformation can broaden the firing temperature and also make the green body have a certain degree of whiteness. At the same time, kaolin has a certain degree of plasticity, cohesiveness, suspension and binding ability, which endows porcelain clay and enamel with good formability, so that the ceramic clay body is beneficial to car blanks and grouting, and is easy to form. If used in wires, insulation can be increased

Properties: much dull, white and fine when pure, and gray, yellow, brown and other colors when it contains impurities. Depending on the origin, the appearance can be loose soil mass and compact rock mass.

Density: 2.54-2.60 g/cm3.

Melting point: about 1785°C. With plasticity, wet soil can be molded into various shapes without breaking, and can remain unchanged for a long time.

Product Usage:

1. After kaolin is dehydrated, it is transformed into metakaolin with high pozzolanic activity. The geopolymeric cement prepared by alkali activation of metakaolin and directly used as concrete mineral admixture can significantly improve the workability, strength and durability of concrete, and it also has a good effect on the autogenous shrinkage phenomenon that exists in high-performance concrete. The inhibitory effect.

2. Pure kaolin with a refractoriness higher than or equal to 1770℃ can be used to make crucibles for smelting optical glass and glass fiber and laboratory crucibles. Low-grade kaolin can be used to make refractory bricks, saggers, refractory mud, tapping mud plugs and burning White cement, etc.

3. As a reinforcing agent and filler, it can improve the mechanical strength and acid resistance of rubber, improve product performance, and reduce costs.

4. To prepare high-performance adsorbents instead of synthetic chemical molecular sieves and used as petroleum cracking catalysts.

5. As a coating for medicine, as a filler for adsorption layer, additives, bleaching agents, detergents, cosmetics, pencils, pigments, and paints.
