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..

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.
25kg, 1000kg, 1200kg, also can be customized.
