Talcum Powder Uses
According to incomplete statistics, talc is used in more than thirty industrial sectors, a total of more than sixty kinds of applications, which are used in the plastics industry, paint industry and many other industries.
1, industrial coatings
Talc is used in many industrial coatings, such as automotive paint, train paint, steel paint, machine tool paint, tank paint, floor paint and so on. The application of talc improves the storage stability of the coating, improves the mechanical properties of the coating film, recoatability, sanding and water resistance. In the coating film, talc as a filler in playing the role of the skeleton, reduce manufacturing costs at the same time, the hardness of the film has also played a role in promoting the improvement.
2、Waterproof coating
Talc can also be used as a filler in waterproof coatings, not only to reduce the volume shrinkage of the coating curing, improve the abrasion resistance of the coating adhesion, reduce costs, but also make the coating has good anti-sinking and heat resistance. Talc good lamellar structure, good performance in adapting to the creep performance of polymer film-forming materials, greatly enhancing the waterproof performance of coatings.
3、Anti-corrosion coating
Talc's lamellar structure gives it many important properties, such as high electrical resistance and low gas permeability; and inactive chemical properties so that it can withstand acid and alkali and a variety of corrosive media, and thus widely used in anti-corrosion coatings. Talc is not only able to change the rheology of the coating, improve brushability, leveling and anti-sagging, the sheet layer is easy to flow with the coating and directional arrangement, the formation of physical shielding layer can prevent the penetration of corrosive media, thus greatly improving the water resistance and moisture resistance of the coating film.
4、Plastics industry
Talc is an important filling agent for plastics, it can improve the chemical resistance, heat resistance, impact strength, dimensional stability, solidity, hardness, thermal conductivity, tensile strength, creep resistance and electrical insulation. It is also a reinforcing agent for many thermoplastics, controlling the rheology of the melt, reducing creep in molded products, increasing the cycle time of molding, and improving the stability of the hot deflection temperature and dimensions. When flake talc is used, it can provide good lubrication to the parts of the molding machine.
5、Other industries
Talc has many other uses, such as for refractory materials, pesticide absorbents, leather coatings, carving materials, etc., but also can make the whole of the saturated foam latex board and the manufacture of floor wax, bleach, corrosion-resistant compounds, lubricants, joint fillers and so on. The above details for you to introduce the knowledge related to talc, can let you understand the characteristics and uses of talc, can have a more detailed understanding of talc, so that in the need, people will be able to correctly use talc, can make its value to be effectively utilized.
