Talc must be surface modified. The purpose is to improve the compatibility of talcum powder and plastic raw materials and improve the use effect.
The higher the purity, the better the strengthening effect. Other mineral impurities and metal minerals in talc have a significant anti-aging function on plastics.
The flotation process of talc powder is relatively simple, only one roughing, one sweeping, and 2-4 times of beneficiation are needed to obtain concentrate.
Fine talcum powder is used in paint coatings, plastics, copper paper coatings, textile lubricants, etc.
Specific surface area: Measured with GSL-101BII laser prismatic analyzer.
