Liaoning talc powder manufacturers introduce talc powder related knowledge

Liaoning talc powder manufacturers introduce Talc powder is an industrial product, a kind of talc of magnesium silicate minerals. Its main ingredient is hydrated magnesium silicate. After crushing, it is treated with hydrochloric acid, washed with water and dried. Commonly used as fillers for plastic and paper products, rubber fillers and anti-blocking agents for rubber products, advanced paints and coatings, etc.

The main component of talc powder is magnesium silicate containing water in talc, and the molecular formula is Mg3[Si4O10](OH)2. Talc belongs to the monoclinic crystal system. Crystals are sometimes pseudo-hexagonal or rhombic flakes. Usually in the form of dense lumps, blade-like, radial and fibrous aggregates. Colorless or white, but light green, light yellow, light brown or even light red due to a small amount of impurities; the cleavage surface is pearly.

Liaoning talc powder manufacturers introduce the functions of talc powder:

It has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good gloss, and strong adsorption capacity. Because talc's crystal structure is lamellar, it easily splits into flakes and has exceptional lubricity.

Liaoning talc powder manufacturers introduce the types of talc powder:

chemical grade

Application: Used as reinforcing filler in rubber, plastic, paint and other chemical industries. Features: Increase the stability of product shape, improve tensile strength, shear strength, bending strength, compressive strength, reduce deformation, elongation, thermal expansion coefficient, high whiteness, particle size uniformity and strong dispersion, etc.

Ceramic grade

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

cosmetic grade

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

food grade

Application: Used as additive in medicine and food industry. Features: non-toxic, tasteless, high whiteness, good adaptability, strong gloss, soft taste and strong smoothness. The PH value is 7-9. It will not reduce the characteristics of the original product.

paper grade

Application: Used for all kinds of high and low grade paper products. Features: Paper powder has the characteristics of high whiteness, stable particle size and small wear. The paper made of this powder can make the paper smooth and delicate, save the raw material and prolong the service life of the paper.

Brucite powder

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