Chemical properties of kaolin

The floatability, floatability, and dispersibility of kaolin refer to the characteristics of porcelain clay that are difficult to deposit when dispersed in water. Also known as anti inclined plate sedimentation tank. Generally, the finer the particle size distribution, the higher the floatability. The porcelain clay used for the production of Tang porcelain industry has excellent floatability according to regulations. Generally, the advantages and disadvantages of its floating characteristics are determined based on the settling speed of the dispersed sample in water for a certain period of time.

Grindability refers to the handmade selection, mechanical processing, and organic chemical solution of kaolin ore to remove harmful residues and achieve the quality specified in industrial production. The grindability of porcelain clay lies in its harmful mineral composition, storage conditions, particle size, etc. Quartz, marble, Biotite, iron and titanium minerals are all hazardous residues. The key to kaolin beneficiation includes new projects such as sand removal, iron removal, and sulfur removal.

Adsorption capacity: Porcelain clay has the ability to adsorb various positive ions and residues from surrounding materials, and has poor ion exchange properties in aqueous solutions. The key to the quality of this characteristic lies in the key mineral composition of porcelain clay.

Organic chemistry is stable, and porcelain clay has strong alkali resistance, but its acid resistance may be poor. This characteristic can be used to generate carbon molecular sieves.

Electrical insulation performance, high-quality porcelain clay has excellent electrical insulation performance, which can be used to make high-frequency ceramics and wireless communication ceramics. The degree of insulation characteristics can be considered based on its ability to withstand electrical penetration.
