Anionic Surface Sizing Agent

Product Specification

Feature

Outstanding film-forming characteristic strengthens paper surface bonding force obviously, greatly improve dry and wet surface strength of cultural paper such as offset printing paper, copy paper and book paper, effectively eliminate paper linting, picking and blanking faults during high-speed rotary printing. The anionic styrene-acrylic copolymer can react and crosslink with starch components rapidly, build a tight protective coating on paper surface, realize even sizing coverage on full paper width and avoid local water absorption difference. Realize the balance of moderate water resistance and ink affinity, effectively inhibit ink bleeding and penetration, make printed text clear, color full and uniform, improve the overall printing presentation effect of cultural paper. Wide process adaptability, suitable for both acidic sizing process with aluminum sulfate and modern neutral papermaking system, good compatibility with various retention aids, defoamers and other wet-end chemicals without system flocculation. Excellent shear resistance and low foaming property, fit for high-speed surface sizing machine continuous production, will not generate bubble pinholes, streaks and other appearance defects on paper surface, guarantee stable operation of sizing system. Optimize paper surface flatness and gloss, narrow the physical performance gap between paper front and back, help paper mills upgrade finished paper quality and product selling price. After surface sizing and drying, the paper can obtain stable water-proof performance directly without waiting for curing, shorten finished paper turnover cycle and improve warehouse utilization efficiency. Effectively slow down moisture back absorption of cultural paper in humid environment, maintain stable surface strength and printing adaptability for long-term finished paper storage. Collaborate with low-cost industrial starch to reduce the addition amount of high-priced sizing agent, bring obvious cost advantages for mass production of cultural paper manufacturers. The finished emulsion has stable storage performance at normal temperature, no demulsification and precipitation during transportation and long-term storage, stable batch-to-batch quality for continuous dosing.
