Product Description

Product Description

The English name of talc powder PULVISTALCI, for white or white, fine, non-sandy powder, hands feel greasy. Odorless, tasteless. This product is insoluble in water, dilute mineral acid or dilute alkali hydroxide solution.

The main component of talc is magnesium silicate containing talc water, the molecular formula is Mg3[Si4O10](OH)2. Talc belongs to the monoclinic crystal system. Crystals are pseudohexagonal or rhomboidal in shape, occasionally seen. It is usually a dense mass, blade, radial, fibrous aggregate. Colorless transparent or white, but due to a small amount of impurities and appear light green, light yellow, light brown or even light red; The cleavage surface has a pearly luster. Hardness 1, specific gravity 2.7~2.8..

Basic characteristic
Talc has excellent physical and chemical properties such as lubricity, viscosity resistance, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good luster, strong adsorption force, etc. Due to the crystalline structure of talc is layered, it has a tendency to easily split into scales and special smoothness. If the content of Fe2O3 is very high, it will reduce its insulation.

Talc is soft, its Mohs hardness coefficient is 1~1.5, slippery feeling, {001} cleavage is complete, easy to split into flakes, natural resting Angle is small (35°~40°), extremely unstable, surrounding rock is silicified and slippery magnesite, magnesite, lean ore or dolomitic marble, except a few moderately stable, generally unstable, joints, cracks

Application

1. The anti-caking agent made from talc powder can reduce the adsorption and adhesion between fertilizer particles.
2. Ultrafine powder blocks the capillary pores on the surface of the fertilizer and prevents the migration of moisture inside the fertilizer particles to the surface.
3. Ultrafine powder is strongly adsorbed on the surface of fertilizer particles, which can well block the contact between fertilizer particles.
4. Control the crystal shape of the particles and keep the particles in the fertilization with a good and stable crystal shape.
5. The anti-caking agent can fix the free water on the surface of the fertilizer, thereby reducing the medium required for chemical reaction and recrystallization.
