Tai'an City, Shandong Xinquan Paper Auxiliary Factory successfully developed a paper can be widely used in cardboard, cultural paper and household paper paper additives - paper stiffening agent, it can improve the stiffness and tensile paper products, Improve its physical properties.
The product is easy to use, less in usage, and the addition of 4kg to 5kg of ton paper in the pulp can increase the stiffness of the paper product and also improve the paper smoothness. In the case where the amount of rosin gum is reduced by 0.2% (for pulp), the sizing degree of the pulp is still stable at 1.0 mm, which can be explained by the fact that the stiffener acts as a colloidal protective agent and enhances the sizing to some extent. effect. At the same time, the ash content of the paper can be increased by 2% to 4%, indicating that the very hard agent also plays a role as a retention agent, which accordingly increases the retention rate of the filler.
