Surface Strength Sizing Agent

Product Specification

Feature

Forms compact cross-linked waterproof film when blended with starch, prominently enhance paper water resistance and moisture-proof capacity, prevent paper softening and structural collapse under high humidity storage and transportation conditions. Capable of direct replacement for wet-end internal sizing agents. No curing time required, stable waterproof performance is obtained immediately after paper drying. Perfect synergy with ordinary raw starch, effectively lower the comprehensive sizing chemical procurement cost for paper mills with no complicated dosing procedures. Outstanding shear resistance and low foaming property during high-speed surface sizing operation, avoid bubble spots and surface defects on paper, and maintain stable circulation of the sizing system. Effectively improve paper ring crush stiffness, surface hardness and surface smoothness, reduce breakage and cracking during subsequent printing, creasing, die-cutting and deep processing of finished paper products. Cationic molecular structure achieves uniform combination with anionic starch, deliver consistent sizing coverage on the entire paper web without uneven water repellency. Small dosage brings dual improvement of waterproof performance and physical strength, delivering excellent cost advantage for long-term continuous production. Strong adaptability for all types of wood pulp, chemical pulp, mixed recycled pulp and mechanical pulp, stable sizing effect amid fluctuations of pulp quality, water hardness and production temperature. Liquid finished product supports automatic metering pump feeding into the starch pipeline, no pre-dissolving preparation needed to simplify workshop operation flow. Reduce sticky deposits on sizing rolls and drying cylinders, cut equipment maintenance & cleaning frequency and extend the service life of paper machine parts.
