Introduction to talc-Amanda International Private Limited

The main component of talc is hydrated magnesium silicate, the molecular formula is Mg3[Si4O10](OH)2. Talc belongs to monoclinic system. Crystals are pseudohexagonal or rhomboid sheets, occasionally. Usually into dense massive, foliar, radial, fibrous aggregates. Colorless transparent or white, but with a small amount of impurities and appear light green, light yellow, light brown or even light red; The cleavage surface is pearly.

With lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, soft, good luster, strong adsorption and other excellent physical and chemical characteristics, due to the crystalline structure of talc is layered, so it is easy to split into scales and special smoothness.

Under normal circumstances relatively stable, no obvious side effects, but long-term large intake is carcinogenic. GB 9685-2008: the maximum use of paint is 2.0%; Plastics (PE, PP, PS, AS, ABS, PA, PET, PC), rubber and paper according to the production needs of appropriate use.

They are divided into three types according to their texture, plasticity and sandy quality fraction:

1.Hard kaolin: hard, no plasticity, after grinding with plasticity.

2.Soft kaolin: soft, strong plasticity, sandy mass fraction <50%;

3.Sandy kaolin: soft, weak plasticity, sandy mass fraction >50%.

Types of talcum powder edit broadcast

chemical grade

Uses: used in rubber, plastics, paints and other chemical industries as strengthening and modifying fillers. Features: increase product shape stability, increase tensile strength, shear strength, flexural strength, pressure strength, reduce deformation, elongation, thermal expansion coefficient, high whiteness, uniform particle size dispersion and other characteristics.

Ceramic grade

Uses: used in the manufacture of high-frequency ceramics, wireless ceramics, various industrial ceramics, architectural ceramics, daily-use ceramics and pottery glazes, etc. Features: No discoloration at high temperature, increased whiteness after calcination, uniform density, good gloss and smooth surface.

cosmetic grade

Uses: It is a high-quality filler in the cosmetic industry. Features: Contains a large amount of silicon. It has the effect of blocking infrared rays, thus enhancing the sunscreen and anti-infrared properties of cosmetics.

Pharmaceutical food grade

Uses: used as additives in the pharmaceutical and food industries. Features: It has the characteristics of non-toxic, tasteless, high whiteness, good compatibility, strong gloss, soft taste and strong smoothness. The PH value is 7-9, which will not degrade the characteristics of the original product.

paper grade

Uses: used in various high and low grade paper industry products. Features: Paper powder has the characteristics of high whiteness, stable particle size and low abrasion degree. The paper made with this powder can achieve smooth and delicate paper, save raw materials and improve the service life of paper.

Brucite powder

Uses: used in the manufacture of electric porcelain, wireless porcelain, various industrial ceramics, architectural ceramics, daily-use ceramics and pottery glaze, etc. Features: No discoloration at high temperature, increased whiteness after calcination, uniform density, good gloss and smooth surface.
