Talc can be used both as a filler for roofing products such as linoleum, roofing paper, asphalt shingles, roofing panels, etc., and as an anti-sticking powder for roofing materials. When used as a filler, talc acts as a stabilizer in the molten asphalt component, increasing the stability and weathering resistance of the roofing material. When sprayed on the surface of asphalt shingles or rolled roofing materials, talc prevents them from sticking during fabrication and storage. The waterproofing industry may use low-grade, colored and impure coarsely ground talc. Talc is a magnesium silicate mineral that is characterized by its characteristic dry slip, low hardness and has a high melting point, good insulating properties against both electricity and heat, low expansion and contraction forces, its high dispersibility, good covering power, oil absorption and hydrophobicity. Great slipperiness, small friction coefficient, stable chemical properties. Resistant to acid and alkali erosion. Because of its stable chemical properties, it is widely used in paper, chemical, paint, ceramics, cable, rubber and other industrial sectors, but also greatly promote the prosperity of talcum powder manufacturers.

Talcum powder is used to improve the rubber and plastic resin molding, calendering, extrusion, injection and other processing properties, and can replace some of the more expensive 10 to 15% to reduce the cost of raw materials and to provide the physical properties of the paints and coatings, resistance to exposure to sunlight, resistance to high temperatures, in the ultraviolet irradiation does not change color, and can maintain the original luster and color for a long time, has a better resistance to corrosion of acids and alkalis, and good water resistance, pollution, ageing resistance, strong, and can be used in a wide range of industries. Pollution, aging resistance, wear-resistant, steam-resistant and strong flame retardant properties of talcum powder has a wide range of uses, the largest amount of paper industry, followed by the waterproof material industry. Talc has its own unique properties: layered structure: talcum powder interlayer van der Waals force is weak so that it is easy to crack into thin layers in the grinding; hydrophobic (lipophilic): that is, lower surface energy, organic matter is easy to adsorb to its layered surface, in the production of colored paper, the addition of talcum powder to reduce the consumption of dyes, effective cost savings, in addition, its surface lipophilicity so that it can be used as resins, adhesives, control agents and waste paper deinking agent; softening and softening agent. and waste paper deinking agent; softness: make the coating surface smooth, supple, can reduce the coating of the break, reduce printing pressure, etc.; lower friction factor: can reduce the abrasion on the equipment (forming mesh, squeegee and printing machine), so as to prolong its service life; chemically inert: does not react with any chemicals, and is not subject to the influence of any other additives, and the other components of the coating has a good compatibility, which also means that the pH value of the change is not sensitive. This chemical inertness also makes it favorable to the environment.
