Calcined kaolin has its own unique production process and is widely used in life. Next, let's explain the specific situation

       Application of kaolin in wire and cable processing: Kaolin functional additive is also widely used in wire and cable processing, especially for EPDM cable. Ordinary wire and low-voltage cable (1 -- 2KV) sheath material PVC and PE resin, except for flame retardant requirements, generally do not need to fill agent, sometimes also add calcium carbonate to reduce costs, improve dielectric properties.

       Application of kaolin in agricultural production: Calcined kaolin has a barrier effect on 7-25μm wavelength of infrared, and the night temperature in agricultural film can be increased by 2-3℃ when modified kaolin is added. It reduces the temperature difference between day and night and is beneficial to the growth of crops. At the same time, the addition of modified calcined kaolin can reduce the direct rays in the agricultural film shed, but increase the scattered rays, and the crops receive uniform light, which is conducive to the photosynthesis of crops. The greenhouse effect of agricultural film in China is relatively poor, the main reason is that the barrier rate of infrared ray is low, the shielding effect is small. Because kaolin's barrier ability is close to mica and the price is moderate, so in the agricultural greenhouse film as insulation agent, can not only improve the insulation of the greenhouse film, but also reduce the raw material cost of the film, is very promising.
