Talc is a kind of silicate mineral, belongs to trioctahedron mineral, the structural formula is (Mg6)[Si8]O20(OH)4. Talc generally in bar, leaf, fiber or radial pattern. The material is soft and creamy. The Mohs Hardness of talc is 1-1.5.
Usage of Talc
Talc has high performances of lubricity, sticky resistance, flow-aiding, fire resistance, acid resistance, insulativity, high melting point, inactive chemical property, good covering power, soft, good gloss, strong adsorption. So, talc has wide application in cosmetic, medicine, paper making, plastic and other fields.
1. Cosmetic: applied in skin moisten, after shave powder, talcum powder. Talc has the function of obstructing infrared ray, so it can improve the performance of cosmetics;
2. Medicine/food: applied in medicine tablets and powder sugar-coating, prickly heat powder, Chinese medicinal formulae, food additives, etc. The material has the advantages of non-poisonous, tasteless, high whiteness, good glossiness, soft flavor and high smoothness.
3. Paint/coating: applied in white pigment and industrial coating, base coating and protective paint, stability of the paint can be increased.
4. Paper-making: used as the filler of paper and paperboard. The paper product can be smoother and finer. It can also save up raw material.
5. Plastic: used as the filler of polypropylene, nylon, PVC, polyethylene, polystyrene and polyester. Talc can increase the tension strength, shearing strength, twisting strength and pressuring strength of plastic product.
6. Rubber: used as filler and adhesive of rubber.
7. Cable: used to increase cable rubber performance.
8. Ceramic: applied in electro-ceramic, wireless ceramic, industrial ceramic, construction ceramic, domestic ceramic and ceramic glaze.
9. Waterproof material: applied in waterproof roll, waterproof coating, waterproof ointment, etc.
Talc Powder Grinding Mill can be used to grind barite, calcite, kalium, steatite, marble, glass, feldspar, etc. Raymond grinder (Raymond mill) is widely used in the metallurgy, building, chemical industry, and mining field..
