Sodium carboxymethyl cellulose (CMC-Na) is an organic compound with the chemical formula of [C6H7O2 (OH) 2OCH2COONa] n. It is a carboxymethyl derivative of cellulose and the most important ionic cellulose adhesive. Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic soda and monochloroacetic acid, with a molecular weight ranging from several thousand to one million. CMC-Na is a white fibrous or granular powder that is odorless, odorless, and hygroscopic, and is easily dispersed in water to form a transparent colloidal solution. In the field of coatings, CMC can be used as a thickener, dispersant, leveling agent and wetting agent, etc., to help the coating better adhere to the surface and improve the smoothness and adhesion of the coating. In the field of paper and pulp, CMC can be used as a wet strength agent, adhesive, dispersant and anti-seepage agent to improve the strength and printing performance of paper. In the field of petroleum drilling fluid, CMC can be used as an important stabilizer and filter agent to help the drilling fluid maintain stability and filtration performance. In the food field, CMC can be used as a thickener, emulsifier and stabilizer to make yogurt, ice cream, jelly, condiments and bread and other foods.

Purification in drinking water, domestic sewage, industrial supply water, industrial sewage, industrial circulating water, urban supply water and urban sewage. It is mainly used in sewage disposal in industries such as printing and dyeing industry, steel mills, sewage treatment plant, paper mill, etc. PAC ADVANTAGES: 1. Ease of application 2. Coagulates very effectively in low as well as high turbidity water. 3. Rapid & better floc formation as compared to Alum. 4. Less reduction of pH compared to Alum. 5. Very less sludge generation. 6. No requirement of other flocculation aids. 7. Reduced Sedimentation Time. 8. Effective in wide pH range. 9. Lower resudual aluminium and other heavy metals as compared to Alum. General Introduction: 1, Aluminium chlorohydrate is a group of salts having the general formula AlnCl(3n-m)(OH)m. It is used in deodorants and antiperspirants and as a flocculant in water purification. 2, Other names for pac are basic polybasic , aluminium hydroxide, and aluminium oxychloride and aluminium chlorohydrate. 3, PAC is composed with a series of different polymerizing power of abio-macromolecule compound, it occupying best configuration distribution, the main content is which has high electricity polymerization link distribution figure provided with Keggin configuration, due to it have high electric neutralization and united function to cooloid and fine substance in the water, it mightly wipe off micro-poison and heavy metal ion, PAC has stable capability and configuration character. 4, synthetic polymers dissolved in water. They react to form insoluble aluminium poly-hydroxides which precipitate in big volumetric flocs. The flocs absorb suspended pollutants in the water which are precipitated with the PAC and can together be easily removed. 5, PAC products are used in water treatment for removal of suspended solid (Turbidity) and other contaminants such as natural organic matter from surface water, Micro - organisms and colloidal particles, silt and clay are stabilized by surface electrostatic charges preventing the particles from coalescing. It is advantageous in water of low to moderate turbidity, possibly because of the greater charge neutralizing capacity relative to alum. 6, Poly(PAC)is a kind of highly effective water purificiant, which is wildly used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water.
At room temperature, it can react with crosslinking agents in the presence of catalysts, to form a reaction product, which has many excellent properties such as keeping good elasticity from -60â?? to 20 excellent electrical property chemical stability and good resistance to water, odor, weather. Therefore, it can be widely used in many industries, such as electronics, semiconductors, autos, mechanicals, fabric, plastic, printing, construction, etc. Viscosity 25,mPa : 2 000/5 000/20 000/50 000/80 000
