Paper-grade talcum powder: It is mainly used as a filler for various types of paper and cardboard. Ultrafine talc can be used with kaolin, calcium carbonate, titanium dioxide pigments to control the gloss, inking, gloss, brightness and opacity of paper.

Plastic talc powder, rubber talc powder, cable talc powder: used to improve plastics, rubber and acid resistance, heat resistance, impact strength, thermal conductivity, tensile strength, creep resistance and electrical insulation properties. Fillers for plastics such as acrylic, nylon, polyvinyl chloride, polystyrene and polyester; rubber fillers and rubber reinforcements and release agents. At the same time, improve the processing performance of rubber.

Talc powder for ceramics: It is used for the ingredients of electric porcelain, radio porcelain, various industrial ceramics, building ceramics, and daily ceramics. It can effectively control the thermal expansion of the ceramic embryo. Talc blocks can also be directly processed into plates for use as furnace linings and kiln linings.

Talc powder for paint: used in water-based, oil-based, resin industrial coatings, primers, protective paints, etc. Talc can be well dispersed in both polar and non-polar matrices, and at the same time has chemical inertness and high absorption rate.

Talcum powder for medicine and food: It is mainly used in pharmaceutical tablets, sugar coatings, gardenia powder, Chinese medicine prescriptions, instrument additives, release agents, etc.

The more calcium oxide in the grey calcium powder, the greater the activity

Water is added to quicklime to become mature lime, and some gray calcium powder produced in some places is made of putty. A layer of skin is burned by hand during construction because the proportion of water added in the production of gray calcium powder is low, and the CAO content of quicklime is high. It has an exothermic reaction, so people feel skin fever and alkaline. This gray calcium powder also has a large draft. Gray calcium powders in areas like Jiangxi, Xiajiang, and Nanyang, Henan are relatively stable with high Ca (OH) 2 content. Small draught, good whiteness, no erosion of hands, draught is generally around 1: 0.5

The more calcium oxide content in the gray calcium powder, the greater the activity. The production of putty easily causes the latex paint to bloom, the production of external wall insulation bonding is easy to pan alkali, the produced toughened coating cannot be stored, and it is easy to discolor ultramarine blue, and the wall surface is pan Yellow, mainly gray calcium powder has high calcium oxide content.
