Usage：
1. Can be used as flocculant for wastewater treatment. It can also be used in industrial fields such as medicine, cosmetics and food industry. It can be used as sizing agent, retention agent and reinforcing agent in the paper industry.
2. Widely used, such as :① chromatographic carrier; ② For water purification, sewage treatment, harmful metals such as cadmium, copper, nickel, chromium, etc., have good chelating ability; ③ glass fiber finishing agent; ④ polymer dyes; ⑤ Make waterproof paper and paper filler; ⑥ Fabric finishing, wax anti-dyeing printing, anti-wrinkle, etc.; 7 Available aneroid fixing and development photography and diffusion transfer reversal photography; ⑧ medically used as a tumor chemotherapy agent, to assist bacteriolytic action, blood anticoagulant, wound healing agent, etc. In the cosmetics industry, it can be used as a cationic thickener. The solution is a colorless translucent viscous liquid. After losing water, a film can be formed. For skin, hair, can form a film, with skin care, hair care, styling functions, so you can prepare cream, mask, mousse, hair spray and other products.
3. Thickeners, emulsifiers, stabilizers, adhesives, pharmaceutical excipients, medical sutures, etc. As an auxiliary material, it can be used as a sustained release agent, lubricant and coating agent. The microparticles, tablets, capsules and microfilms of the corresponding drugs can be prepared by direct pressing, wet granulation or coating. It can be made into dialysis membrane, ultrafiltration membrane and reverse osmosis membrane. The iso-chain complex with fiber can be formed into molecular sieve. As a crosslinking agent with glutaraldehyde, it can be immobilized with many enzymes or microbial cells, such as immobilized asparaginase. Can be used for artificial skin, artificial blood vessels, artificial kidney and so on. Glycan can inhibit gastric ulcer and reduce cholesterol and blood lipid.
