Talc powder can increase the volume of rubber and improve the machinability of rubber

1. Silica content of talc powder; When the silicon content of talc reaches a certain amount, it can be called transparent talc powder. The more silicon, the better the quality of talc powder. That is to say, the content of silicon directly determines the quality of talc powder.

2. Molecular characteristics of talc; Talc lamellar structure more complete, is the molecular shape, the better, polishing the talcum powder, the more transparent, in general, the impurities in the remains of molecular properties are not complete, so transparent talcum powder must be made of complete talc lump.

3. Source resources; The biggest producing area of talc powder in China is shandong talc powder, among which, the pingdu talc powder is the best quality, depending on the mountains and near the water, rich in mineral resources, and it is the fengshui land for producing talc powder.

Belongs to triclinic crystal transparent talcum powder, white, tasteless, usually precision block, lamellar, fibrous, surface smooth, texture, exquisite, refractory acid, Qingdao sheng yida talcum powder co., LTD., as a professional talcum powder manufacturers, explain for everybody affect the transparency of talcum powder:

The main component of talc is hydrated magnesium silicate. Talc belongs to monoclinal system. The crystal is a pseudo - hexagonal or diamond - shaped sheet, occasionally seen. It is usually a dense mass, leaf, radial and fibrous aggregate. Colorless transparent or white, but light green, light yellow, light brown or even light red due to a small amount of impurities; The cleavage surface is of pearl luster. Hardness 1, specific gravity 2.7 ~ 2.8. Talc with lubricity, sticky, flow resistance, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good luster, strong adsorption force and other excellent physical and chemical properties, due to the crystallization of talc is a layered structure, so the easier to split into flake trends and special lubrication, if the content of Fe2O3 high will reduce its insulation.

Coarse whiting powder is widely used in building materials, rubber, paper, paint, paint, printing ink, cable, food, medicine, feed, daily chemical industry such as toothpaste, as a filling agent rise to increase the volume of products, reduce the production cost, the effect of use can increase the volume of the rubber in the rubber, to improve the rubber processability, half reinforcing or reinforcing effect, and can adjust the hardness of the rubber; Used in chemical building materials, with heat resistance, chemical corrosion, cold resistance, sound insulation, shock resistance and easy processing.
