Product Description

Product Description

 

Calcined kaolin are produced from highly refined kaolin through grind, calcination and Classification. It has high purity and the quality is stabled. It offers superfine particle and with excellent anti-settling property; It can easily disperse in water based systems; It is inert to most acids and alkaline at Ambient temperature and offers good anti-corrosive capabilities.

Kaolin is a mixture of inorganic nonmetal, calcined kaolin is calcined kaolin in sintering furnace to a certain temperature and time, the physical and chemical properties which has a certain change, in order to meet certain requirements.

Compared with the non calcined kaolin and calcined kaolin, calcined kaolin with reduced water content, silica and alumina content increased three, the activity increases, changes in the structure, the particle size is small and uniform, compared with non calcined kaolin filled NR rubber, vulcanized low temperature characteristic curve of calcined kaolin filled NR compound consistent.
