Usage:
Talc has excellent characteristics such as heat resistance, smoothness, acid and alkali resistance, insulation, and strong adsorption of oil. Widely used in various industrial fields such as ceramics, paint, felt, papermaking, textiles, rubber, coatings, and daily chemical industry.
The papermaking industry is the main application field of talc, which can be used as coatings and fillers. Ultrafine talc powder can be used together with kaolin, calcium carbonate, and titanium dioxide pigments to control the inking, gloss, brightness, and opacity of paper;
The textile industry utilizes the low wear and high whiteness of talc as a filler and whitening agent for textiles;
The paint industry, as a filler, can improve the dispersion of coatings;
In the cable, plastic, and rubber industries, it is used as a filler to improve the acid and alkali resistance, heat resistance, impact strength, thermal conductivity, tensile strength, creep resistance, and electrical insulation performance of plastics and rubber. At the same time, it can improve the processing performance of rubber; Ceramics and refractory materials are used as ingredients and glazes in the industry, which can effectively control the thermal expansion of ceramic bodies and provide a cheap source of magnesium oxide as glazes. Talc blocks can be directly processed into sheets and used as furnace lining, kiln lining, or insulating electrical panels. It can also be used as a filler for cosmetics, a carrier and additive for medicine and food.
