Introduction:
Kaolin is widely used in the paper industry. There are two main areas, one of filling materials used in the paper (or dipping) process, and the other is the use of pigments in the surface coating process.Kaolin used in paper making, to give the paper and good coverage properties and good performance of the coating gloss, but also to increase the whiteness of the paper, opacity, smoothness and printability, greatly improved the quality of the paper.
