Cable grade talc powder

Cable grade talc powder: product features:

It can improve the wettability of the polymer, enhance the strength of the product, and also can be used as an isolating agent, surface treating agent and filler. It has strong acid and alkali resistance and is used for acid and alkali resistance, heat resistance and insulation products.

Applicable fields:

Used as antiadhesive for rubber stuffing and rubber products; Used for cable rubber reinforcing agent and cable isolating agent.

Cable talc: PULVISTALCI is a white or white, fine, non-abrasive powder with a greasy touch. No smell, no smell. This product is insoluble in water, dilute mineral acid or dilute hydroxide solution. It can be used for medicine.

Molecular structure of cable grade talc

This product is a mineral talc of magnesium silicate and mineral talc. Its main component is magnesium silicate containing water. After crushing, it is treated with hydrochloric acid, washed with water and dried.

composition

The main component of talc is hydrated magnesium silicate, whose molecular formula is Mg3[Si4O10](OH)2. The crystal is a pseudo - hexagonal or diamond - shaped sheet, occasionally seen. Talc is a monoclinal system. 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.

Cable grade talc characteristics

Talc soft, its for 1 ~ 1.5 mohs hardness coefficient, have slippery feeling, {001} cleavage is extremely full, easy to split into slices, natural rest Angle is small (35 ° ~ 40 °), very solid, the surrounding rock of silicide and petrochemical magnesite, lingmei rocks, lean ore or dolomitic marble, with a few solid medium, generally are not solid, joint, crack development, physical and mechanical properties of the ore and surrounding rock is a big influence on mining process.

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.
