Application of kaolin in paper making industry
Application of kaolin in paper making industry
The paper industry is the largest market for kaolin, and the dosage is far more than that of ceramics, plastics, rubber and paint
In the paper, kaolin can be used as a filler and coated cloth, because the kaolin in the pulp and other ingredients and chemical reaction, with a solid, well preserved in the paper fibers; meanwhile, kaolin fine granularity, easy to flow, can adapt to the mechanization of high-speed production, can ensure the film thickness of coating paper the surface of the uniform. As filler, according to the number of degrees stable in the pulp of kaolin decided to join the stable degree of kaolin filler in the pulp is generally 35% ~ 60%, the robustness and the fineness of kaolin, the best fineness is 2 ~ 20 m. The packing is the role of the gap between the wood fiber filling in paper, to improve the paper density and surface smoothness, reduce its transparency, to ensure better absorption of ink color. When coating, it is to use the capacity of kaolin coating, the role is to flake kaolin particles coated on the surface of the paper, so that it is smooth, bright, clean, opaque and printable. In other words,
Kaolin as filler, which can be used as extender, partial substitution of expensive materials, and does not affect the properties of the final product, but also can be used as functional fillers, pigments as enhance whiteness. Kaolin as coating fabric, its function is to improve the compatibility, ink on paper permeability and appearance.
Papermaking industry on kaolin quality requirements can be summarized as follows: the content of kaolinite is good, the main content of Al2O3 and SiO2 is close to the theoretical value of the better, the content of Al2O3 paper gloss, high Al2O3 content increased the gloss of the paper, the SiO2 content is too high, will affect the gloss of the paper, and improve the kaolin the hardness, the wear value increased, affecting the quality of the paper. The less chromatic components, Fe2O3, TiO2, the better. Sulfuric acid anhydride (SO3) causes a paper for a long time preservation and yellowing phenomenon. Mineral crystal form as thin as good, easy to make the coating thixotropic, and can increase gloss, particle size and thickness ratio of 8 to 1 is appropriate, tubular crystal shape will reduce gloss, increase viscosity. The whiteness of kaolin is as white as possible. The viscosity value of kaolin is higher, but its viscosity is low and its flowability is good. Such as for the scraper coating kaolin, whiteness requirements greater than 85%, the viscosity concentration value is greater than 70%, the particle size distribution should be appropriate, but not the finer the better, there must be a certain grade, <10 mu m is greater than 98%, <2 mu m is greater than 85%, <0.5 mu m is less than 10%.
