Sodium sulfite, an inorganic substance with chemical formula Na2SO3, is a sulfite, which is soluble in water and insoluble in ethanol. Insoluble in liquid chlorine and ammonia. It is mainly used as artificial fiber stabilizer, fabric bleaching agent, photographic developer, dye bleaching deoxidizer, perfume and dye reducing agent, papermaking lignin removing agent, etc. Product implementation standard HG/T2967-2010.
Solid Retention Polymer Retention agent is a water-soluble, linear organic polymer. Could enhance the drainage of the wire, improve the retention of small fibers. Advantage: Improve the quality of the paper, such as bonding strength, tensile strength. Save cost by increasing filler retention. Improve whitewater circulation system. Improve paper formation. Improve drainage efficiency. Features: The best retention of fine particles and colloids in the papermaking process normally occurs when the zeta potential is near to zero and retention aid doing that. The main functions of retention aid are following: Improve the quality of the paper, such as bonding strength, tensile strength. Reduced wet-end additives and sizing usage. Improves paper machine runnability
are water-soluble polymer products. The most commonly used solutions are formulated with polyamide-epichlorohydrin (PAE) resin chemistry and are intended primarily for the consumer market. PAE resins function in neutral/alkaline papermaking processes. They have a high level of Wet strength agent permanence, help improve machine efficiency and do not adversely affect paper absorbency. Advantage: Paper production efficiency: After using the product, the paper production efficiency will be improved. Wet strength effect: Easy to absorb water, with obvious anti-scratches effect. With excellent performance of keeping luster and color, do not reduce the whiteness of original fiber. With stable chemical properties and good compatibility. Features: The product has good characteristic to reduce the problem of dropping off powder which is can widely used in the tissue, package paper, culture paper and other kinds of wet strength of paper production.
Chemical Name: Liquid High Retention Etherification Agent (CHPTAC) English Name: 3-Chloro-2-hydroxypropyl trimethyl ammonium chloride (CHPTAC) Appearance: Colorless transparent liquid Active Matter Content: 69% Impurity Content: 1,3 - dichloropropanol: â?¤ 15PPm Epichlorohydrin: â?¤ 5PPm PH: 4.0-7.0 Density: 1.16 (20�°C) Usage: Widely used in paper industry Features and usage: By altering the cationic etherifying agent's molecular structure, the starch's DS increases without impacting gelatinization temperature. This elongates the starch chain and enhances charge adsorption through increased branching. When applied at the wet end, it reinforces and retains fibers, elevating ash, whiteness, and opacity of paper. Energy is conserved, breakage minimized, and starch usage reduced, yielding multiple benefits.
