What are the properties of ultrafine talc powder?

Ultra-fine talc powder is made from talc that has been carefully purified, crushed and dried. It is a white or off-white, fine, sand-free powder that feels smooth to the touch; odorless and tasteless; ultrafine talc powder has been widely used in many industries, mainly because of its above characteristics.

Adsorption: high oil absorption value, improves the printability of paper ink, reduces resin obstacles during paper operation, improves white water cleanliness, and is also a good waste paper deinking aid, which is beneficial to improving the organic additives in the wet end of the paper machine. Retention;

Lubricity: Improve paper adhesion and production operability, give paper good feel, softness and finish, and reduce the amount of coating lubricant.

Chemical stability: It is suitable for various papermaking sizing systems. Compared with fillers such as calcium carbonate and kaolin, it can save the amount of chemical additives added and give the paper a good sizing effect. It can be used with various pigments, latex, etc. in coating systems. The auxiliary additives have good compatibility, soft texture, low hardness, low abrasion, high crushing ratio, and relatively easy powder processing. They can reduce the wear of processing equipment, papermaking and printing equipment, and improve the paper finishing effect.

Hydrophobicity: Improve the water resistance of paper and reduce the hygroscopicity of the finished paper. The flake structure gives the coated paper good smoothness, gloss, roughness, hiding power and printability. It can replace water-selected kaolin for paper coatings. Ideal mineral.
