【Products】Super-fine calcined kaolin（3000-mesh）

【Product detail】

Yuanjiang Brand - ultra-fine calcined kaolin 3000 mesh are widely used in papermaking industry, there are two main areas, one is used as a filler in papermaking process, 2 it is used as a pigment in the surface coating process.As a pigment, kaolin can not only give good covering properties and coated paper burnish performance, also can increase the paper whiteness, opacity, smoothness, and printing eligibility, greatly improve the quality of the paper.

Kaolin filler can take the place of some more expensive materials, effectively reduce the production cost at the same time, the guarantee does not affect the final product properties.For general cultural paper, packing volume accounts for 10-20% of paper weight.For coated paper and cardboard (mainly include lightweight coated paper, coated paper and coated paper board), in addition to the need to packing, you also need to paint, fillers with kaolin proportion for paper weight of 20-35%.
