How to remove soluble substances and colloids by cationic nano-particles in the production process of paper making and cationic nano-particle sol,

摘要

[Challenge] cationic nano-particle sol, and I will provide a papermaking process by it. By [MEANS FOR SOLVING PROBLEMS] cationic nano-particle sol, soluble contaminants and colloid in the water is removed in the papermaking process, yet let strained left in the paper in the papermaking process, it is removed from the water along with the paper products. Therefore, the specific surface area of cationic nano-particles is greater than ² / g 200m, it is up to 5000m ² / g, the molar ratio of cationic polyvalent metal / silicon surface 1: 1: 8 to 30.
