Talc has chemical stability, low hardness, lubricity, lamellar structure, lipophilicity and hydrophobicity. Proper use of talc in the paper industry can effectively improve the performance of paper. In China, more than 50% of the output of talcum powder is used in the paper industry. Its applications mainly include paper filler, coating and resin control agent. HCMilling(Guilin Hongcheng) is a professional manufacturer of talc grinding mill. Our talc production equipment has been widely used in the paper industry and has a good reputation. The following describes how to produce talc powder for paper making?

The production of talc powder for paper making mainly consists of three steps: beneficiation, crushing and grinding. Different fineness requires different talcum powder production equipment. At present, dry processing is the main processing method of talc powder in China. Based on the excellent natural fragility and grindability of talc, the talc grinding mill produced by HCMilling(Guilin Hongcheng) mainly include three types: talc Raymond mill, talc vertical roller mill and talc ultra-fine mill. Talc Raymond mill is usually used to process the matching talc powder for paper making with a mesh size of 325, and the talc ultra-fine mill is usually used to process the ultrafine talc powder with a mesh size of 1250-2500.

 

Talc plays an important role in the papermaking industry due to its unique hydrophobic property. Talc has the following advantages when used as filler in the papermaking process:

 

(1) It is conducive to improving the smoothness, opacity and printability of the paper

(2) Low wear value, which can prolong the service life of the paper web

(3) Stable chemical properties, not only suitable for acid paper making, but also for neutral paper making in combination with calcium carbonate

(4) Good combination with sizing agent to retain the sizing material and prevent the penetration of printing ink

(5) It is lipophilic and can adsorb organic substances to keep the white water and pulp system clean. As a filler, it can also remove the resin barrier, which is helpful for the removal of ink in waste paper deinking

(6) With certain hydrophobicity and lubricity, it can reduce the water absorption of the paper, improve the smoothness and softness of the paper, and reduce the operation obstacles such as calendering and finishing

(7) It is beneficial to retain in the paper and reduce the fiber consumption per ton of paper products.
