Pulp water retention value is a key hidden index affecting papermaking dehydration efficiency and finished paper dimensional stability. High water retention value means pulp fibers contain a large amount of bound water and adsorbed water that are difficult to drain, which seriously reduces the dehydration speed of the pressing section, increases drying steam consumption, and restricts the operating speed of high-speed paper machines. Pulp with excessive water retention value is prone to uneven water distribution during forming, resulting in inconsistent drying shrinkage, paper wrinkling and warping deformation. In recycled pulp production, repeated beating and fiber fragmentation will further increase water retention value, forming a vicious cycle of high energy consumption and unstable quality. Most traditional dehydration agents only remove free water on the fiber surface and cannot reduce bound water content inside fibers, so the energy-saving and efficiency-improving effect is limited. Excessive use of chemical dehydrators will damage fiber activity and reduce finished paper strength. Shandong Ludao Energy Technology Co., Ltd. develops targeted pulp water retention optimization technology. By changing fiber surface hydrophilic characteristics and releasing internal bound water, we effectively reduce pulp water retention value without damaging fiber structure and physical activity. The solution accelerates pulp dehydration efficiency, reduces drying energy consumption, stabilizes paper forming and shrinkage uniformity, and realizes energy-saving, high-speed and high-quality papermaking production.
