Application:
1.Paint and Coating :As a pigment and functional filler, it has the following advantages:
Firstly,it can replace 20%-30% titanium dioxide and Lithopone, greatly reducing the production cost.
Secondly,calcined kaolin has good anti-precipitation effect and excellent dispersive suspension performance, so that the product has a good canning effect.
Thirdly,good leveling, washing resistance and weather resistance.
2.Plastic Cables: The use of kaolin can improve the product's strength, anti-aging performance and insulation performance, and the volume specific gravity has a high requirement, generally 1250 mesh, 80-85 degree of whiteness in low temperature calcining is better.
3.Paper Making:It can partially replace titanium dioxide in copper board paper, white board paper and other paper, reduce production cost, improve paper strength, whiteness, brightness, flatness, printing color, whiteness requires more than 90%, viscosity concentration pass-screen rate, abrasion and other indicators have requirements.
4.Rubber Industry: Calcined kaolin has the advantages of high purity, non-volatile, low heavy metal content and moderate pH value. It is used as a reinforcing agent in the rubber industry to improve the strength and performance of products, such as crack resistance, tear resistance and wear resistance.
5. Other Industries:Such as ceramics and refractories, precision casting, wear resistant materials, polishing materials, ink and other industries.
