1.Purity Calcined Kaolin Introduction :
It is made from kaolin material, (Kaolin divided into from industry: Hard kaolin,Soft kaolin,Sandy clay), Calcined kaolin clay is calcined to a certain temperature deep-processing products in the calciner,Calcined kaolin calcined during
dehydration and the volatiles were removed, Fired at different temperatures with different physical properties of a calcined kaolin .
2.Purity Calcined Kaolin Physical Properties :
Whiteness | Oil Absorption | PH | Moisture |
92-98% | ≥62% | 6.5-7.5 | ≤0.5% |
Chemical indicators
SiO2 | Al2O3 | Fe2O3 | TiO2 |
52-54% | ≤48%-56% | ≤0.35%-3% | ≤0.1-0.5% |
3.Purity Calcined Kaolin Main using :
1)In paper industry: Calcined kaolin are widely used paper coatings and fillers
2)In rubber industry: mainly use as a Reinforcing agent and filler used ,rubber product can be improved Solvent resistance and abrasion resistance
3) In plastics and cable industry: Plastics can effectively improve the strength and modulus of resistance ,Without reducing the ductility and impact strength,Can also improve the performance of products.
4). In polyvinyl chloride(PVC)cable insulation outer: PVC plastic product can exponentially increase the volume resistivity And inexpensive,In thePVC flooring productcanimprove performance and surface gloss
5) In nylon: To improve its deflection and tensile strength,In film and tape use as an Anti-clogging agent,In plastic
sheeting to use as adsorbent, etc .
