Oxidized starch as the important component of surface sizing agent,due to the its’ strength is not enough after the film, so with the continuous evaporation of moisture in the drying process and film shrinking and prone to rupture phenomenon,And after will be a mixture of oxidized starch and surface strengthening agent has good film-forming performance. Used for production of Offset paper, electrostatic copy paper, copperplate paper, high-grade cultural paper. Can significantly increase the surface strength of paper, reduce the wool powder,Printing paste version phenomenon etc. Also can prevent ink excessive infiltration,reduce telegraphing phenomenon, so as to achieve the purpose of improve the quality of printing; When used in production of high-strength corrugated base paper and other paper, can help improve the ring crush strength, stiffness, etc.
