Introduction to Calcined talc-Amanda International Private Limited

Main ingredient

The main component of talc is magnesium silicate containing water, and the molecular formula is Mg3[Si4O10](OH)2. Talc belongs to the monoclinic system. Crystals are pseudo-hexagonal or rhombic flakes, occasionally. Usually into dense massive, leaf-like, radial, fibrous aggregates. It is colorless, transparent or white, but appears light green, light yellow, light brown or even light red due to a small amount of impurities; the cleavage surface is pearly. The hardness is 1, and the specific gravity is 2.7~2.8.

Basic Features

Talc has excellent physical and chemical properties such as lubricity, anti-sticking, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good gloss and strong adsorption. The crystal structure of Fe2O3 is layered, so it has a tendency to split into scales and special lubricity. If the content of Fe2O3 is high, its insulating properties will be reduced.

Talc is soft, its Mohs hardness coefficient is 1~1.5, it has a slippery feeling, the {001} cleavage is very complete, it is easy to split into flakes, the natural angle of repose is small (35°~40°), very unstable, and the surrounding area is very unstable. The rock is silicided and talcated magnesite, magnesite, lean ore or dolomite marble, except for a few moderately stable, generally unstable, joints and fissures are developed, and the physical and mechanical properties of the ore and surrounding rock have an impact on the mining process. The impact is huge.

Folding chemical grade

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

Folding ceramic grade

Folded 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.

Folding 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.

Folding 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 grease network.
