XQ-1 paper dry strength enhancer is used to form a large number of hydrogen bonds in the pulp, and then play a role in the formation of a large number of crosslinks in the drying process of the paper machine, XQ-1 contains a large number of hydroxyl, amide and carboxyl groups, etc. The active gene, when added to the pulp, rapidly adsorbs on the surface of the fiber and forms a large number of hydrogen bonds with the hydroxyl groups in the fiber surface; during the drying process of the paper machine, a large amount of cross-linked bonds are formed, thereby significantly increasing the binding strength thereof. , To achieve the purpose of increasing the dry strength of the paper.
