Paper Sizing In Paper Making Process
Paper sizing generally has two methods: one is surface sizing, that is, after the paper is formed and dried, the sizing agent can be applied to the surface of the paper by a size press, a coater, or a calender; The method is internal sizing, which adds the sizing agent to the papermaking stock and achieves bonding with the paper web during sheet formation. The results of both processes can reduce the paper’s wettability with water, and surface sizing can also reduce the porosity of the paper.
AKD neutral sizing agents are widely used as mature sizing agents. As an ideal product for a new generation of medium/alkaline sizing, AKD can significantly increase paper strength, improve printing performance, overcome the shortcomings of rosin gum summer sizing difficulties, and reduce corrosion of equipment.
