CMC is widely used in frozen desserts, protein food, beverages, icings, dressings, instant noodles, etc. 1, a main physical and chemical properties, the CMC is a linear ion-polymer material, pure white or slightly yellow, fibrous powder, non-toxic, tasteless and soluble in hot and cold water to become transparent solution viscosity, Natural Rubber and general syntheic did not have many advantages, which are widely used in food processing, beverages, textiles, paper making, Oil drilling, daily chemicals, paint, tobacco, building materials, ceramics, Coil, detergents, and other industrial and unique thickener, binder, emulsifier, aquasorb, dispersion, suspensions, puffing sexual fixing agent, retarders in all sectors play their role, commonly known as the "industrial MSG" two, the use of a small amount of water infiltrating it, and then add water, stirring as necessary preparation concentration of the solution. For other ingredients, excipients and will be the best blending of CMC, in the solution of high-speed stirring gradually input can be fast dissolving. We should also be careful in high-temperature, the viscosity will reduce the temperature rise, as CMC easily absorb moisture users attention to packaging intact, Moistened products to avoid dissolution. Benpinwei non-dangerous goods. CMC quality indicators 1, industrial and oil level indicators of the quality of CMC LevelProduct codeQuality standardsReplace degrees.S)≥Purity≥Viscosity25PHSize (60 head)%Drying reductions ≤Industrial gradeIL60.50-0.705550-40*8.0-11.58010IL80.8075<3007.0-9.0808LM60.6045300-8006.0-8.5808IMH80.8092≥6006.0-8.58010LH60.6092800-12006.0-8.5808LH80.8092800-12006.0-8.5808LH90.9097800-12006.0-8.5808ISH90.9097>12006.0-8.5808Oil-LV-CMC0.8080 7.0-9.08010MV-CMC0.6585 7.0-9.08010HV-CMC0.8095 6.5-8.080102, CMC-oil drilling fluid performance indicators LevelProjectIndicatorsDistilled waterBrineSaturated brinePulp basisFiltrate lossml)50±1090±10100±10The apparent viscosity(mpa.s)≤6≤6≤10PH8.0±1.08.0±1.07.5±1.0HV-CMCCreate slurry ratem3/t≥200≥150≥160LV-CMCFiltrate lossQuantityg/l ≤7.010The apparent viscositympa.s) ≤4.0≤6.0MV-CMCQuantity6.014.023.5The apparent viscosity mpa.s)≥15≥15≥15Filtrate loss ml)≤9≤9≤83, building materials, ceramics, mosquito coils, and paper industries of Specs indicatorsParticularly high   Solution Viscosity mpa.S≥1200800-1200300-800500-800Degree of substitution .S)≥0.60≥0.60≥0.60≥0.60PH6.0-8.56.0-8.56.0-8.56.0-8.5Drying reductions≤10≤10≤10≤10Purity>90>90>90--4, the food-level technical indicators LevelProduct codeThe main technical indicatorsViscosity mpa.S)Drying reductions ChlorideSodiumFeAsPb %Food GradeSM6400-800≤106.0-8.0≤1.86.5-8.5≤0.03≤0.0002≤0.002SM7800-1200≤106.0-8.5≤1.86.5-8.5≤0.03≤0.0002≤0.0025, the tobacco industry ICH7 Specs indicators  CMC mainly for the production process of bonding tobacco sheet, the CMC is characterized by fine powder, dissolved faster, high bond strength, and to reduce the cost of tobacco is very favorable.Solution Viscosity mpa.S≥1200800-1200Degree of substitution.S)≥0.60≥0.70Purity6.0-8.5>90PH≤106.0-8.5Drying reductions>90≤106, the textiles industry Specs indicators  Textile Industrial CMC, CMC substituting machinery Sizing enable a smooth surface, wear soft Loom increased production capacity.
