Alkali resistance is an essential functional index for building packaging paper, alkaline industrial wrapping paper and plasterboard backing paper. In industrial production and building construction scenarios, paper often contacts alkaline cement mortar, alkaline dust and alkaline cleaning liquid. Ordinary paper fibers will hydrolyze rapidly under alkaline environment, leading to fiber fracture, strength loss, surface peeling, discoloration and pulverization. Poor alkali resistance makes paper lose basic protection and bonding performance in alkaline scenes, greatly limiting its application in building materials and chemical industrial packaging fields. Common waterproof agents only resist liquid water, cannot isolate alkaline ion corrosion, and will be decomposed by alkaline substances to fail quickly. Few alkali-resistant modified products on the market will harden paper sharply, damage processing folding performance. Shandong Ludao Energy Technology Co., Ltd. develops targeted paper alkali-resistant modification technology. It builds dense alkaline-isolation molecular film on fiber surface, blocks penetration and erosion of alkaline ions, inhibits fiber alkaline hydrolysis reaction. The modified paper maintains stable strength, color and structural integrity under long-term alkaline contact, keeps good folding and cutting performance, adapts building material matching and alkaline industrial packaging usage, helps enterprises develop special anti-alkali functional paper series.
