What are the main uses of talc powder in papermaking? 800 mesh talc powder

Flatness talc manufacturer’s analysis: The main use of talc in papermaking is as filler and pigment in coated paper. 1. The main use of talc powder in papermaking is as filler, and it is the most widely used papermaking filler in China. It has the characteristics of rich treasures, low price and high adaptability to paper performance. Talc flatness Talc powder price is smooth and chemically inactive. Adding it to paper can improve the evenness, smoothness, gloss and ink absorption of the paper, improve the printability and writing of the paper, and is widely used in printing. Filling with common cultural paper for writing and other purposes. Because of its low refractive index, it is rarely used in tissue paper. Flatness Talc Powder Manufacturer 2. Comparative Flatness Talc Powder Manufacturer When talc is used as a filler, whether it is necessary to add filler during production, what kind of filler to use, and the amount used are all based on the quality requirements of flatness talc powder price paper, It is determined by its use and the characteristics of the filler itself, as well as production costs and economic benefits. Filling can improve the opacity, air permeability, flexibility, printability and writing properties of the paper, and reduce costs. However, it will also reduce the physical strength and sizing degree of paper sheet flatness. The difference in properties between talc powder and kaolin is mainly reflected in the whiteness. The whiteness of talc is 90% to 96.8%, and the whiteness of kaolin is 80% to 86%. Therefore, in comparison, talc powder manufacturers who have relatively high requirements for smoothness also use talc powder. However, talc is generally less used in the production of tissue paper (such as tissue paper). Talcum powder is a magnesium silicate mineral. It has unique dry slipperiness, low hardness, high melting point, good insulation against electricity and heat, low expansion and contraction force, high dispersion, and strong hiding power. It has good oil absorption and hydrophobicity, large smoothness, small friction coefficient, chemical flatness, stable talc powder, and resistance to acid and alkali erosion. Because of its stable chemical properties, it is widely used in papermaking, chemical industry, paint, ceramics, cables, rubber and other industries. Talc powder is mainly divided into chemical grade talc powder, ceramic grade talc powder, cosmetic grade talc powder, pharmaceutical and food grade talc powder, papermaking grade talc powder, brucite powder and calcium carbonate powder. In industry, it can be used as a reinforcing modified filler in rubber, plastics, oil level talcum powder paint, and other chemical industries; it can be used in the manufacture of electrical porcelain, radio porcelain, various industrial ceramics, building ceramics, daily ceramics and ceramics. In glaze and other industries, it can achieve the effects of no discoloration at high temperatures, enhanced whiteness after calcining, uniform density, good gloss, and smooth surface; used in products in various high- and low-grade papermaking industries to make the paper smooth and delicate. , and can save atomic materials and improve the service life of the grease network; flat talcum powder is also widely used in the manufacturing of high-frequency porcelain, radio porcelain, various industrial ceramics, architectural ceramics, daily ceramics and ceramic glazes. It can be used as a high-quality filler in the cosmetics industry. Talcum powder is also often used as an additive in pharmaceutical and food industries. Talcum powder has a wide range of uses and low cost. Talc powder has great development prospects in the future market.
