CMC / Carboxymethylcellulose Sodium Industrial GradeFloating Price. Please Contact me if you have any question or requirement.Product Description:Sodium carboxymethyl cellulose (CMC)
It is an anionic polyelectrolyte made from sodium chloroacetate reacted with alkali cellulose and divided into high viscosity (HV-CMC),
Medium sticky (MV-CMC), low viscosity (LV-CMC) and alkaline sticky, the appearance of white or gray powder, non-toxic, soluble in cold water or hot water, water solution is viscous colloid.
The CMC is mainly responsible for the effect of viscosity of filtrate reducer for drilling fluid, sodium carboxymethyl cellulose and a plurality of long molecular chains adsorbed on clay particles, cementation can increase the mud cake, can inhibit shale hydration expansion and consolidation of the wall effect. Aqueous solution of sodium carboxymethyl cellulose has many excellent properties and chemical stability, easy corrosion, physical safety and harmless, and also has a suspension and emulsification effect, good adhesion and anti salt ability of oil and organic solvents has good stability, therefore, is widely used in petroleum, food, textile, medicine papermaking and chemical industry field. Wash Hao essence is added. The viscosity of high transparent. Do not return. The dilute liquid detergent effective thickening and stable composition. Washing powder. Add washing liquid can prevent the dirt has been washed again in settlement fabric. Synthesis of 0.5-20% to obtain the detergent against the satisfied results::1.CMC can be used as cementing fluid to prevent fluid into the pores and cracks, used as fracturing fluid can control the fluid into the well to the loss of stability. Because the filter bag item screen for M 7. a 3 value filter, liquid or solid, or to control 2%1 water gap; 0 full quality 5 heavy
2.CMC can control the rheological property of slurry well and has good non Newtonian fluid. Liquid 1 coated paper value and 6% base cow Ms stable water quantity, C good.2 contact energy can be damaged as far as possible a 0, no C2 degrees, a g, three of slurry loss
3.CMC can make the quality of clay cake good, firm and tough
First, the main physical and chemical properties of thickener CMC:
1, CMC is a linear type ion polymer material, the pure product is white or slightly yellow fibrous powder, non-toxic, tasteless, soluble in hot and cold water become transparent viscous solution, with natural rubber and synthetic rubber have many advantages for Hu. Widely than food processing, beverage, textile, papermaking, petroleum drilling, daily chemical industry, building materials, ceramics, paint, cigarette, mosquito coils, detergents and other industries, has a unique thickener binder, emulsifying agent, sizing agent, water retaining agent, dispersion, suspension, expansion of fixing agent, retarder, excipients play their own in various industries, commonly known as "industrial monosodium glutamate".
2, use a small amount of water to make it infiltrate, then add water and stir to prepare the required concentration of the solution. If other ingredients are needed, it is best to mix the excipients with CMC and gradually pour into the water solution at high speed to dissolve rapidly. At the same time should pay attention to high temperature, viscosity will be due to rising temperature and reduce, because CMC easy moisture absorption, users pay attention to packaging intact, in order to avoid product moisture dissolved. This product is not dangerous goods. Two, CMC quality index: application in building materials, ceramics, mosquito coils, papermaking industry specifications: IH6 IM6 OM6 2% IH6 extra high viscosity of the aqueous solution of mpa.S = 1200 800-1200 300-800 500-800 DS (D.S) = 0.60 = 0.60 = 0.60 = 0.60 6.0-8.5 6.0-8.5 6.0-8.5 6.0-8.5 dry pH reduction% less than 10 below 10 below 10%>90 >90 >90, less than 10 purity of CMC used in building materials as retarder, water retaining agent, thickening agent and binding agent. After adding CMC, the coating has better elasticity, tightness and water resistance. CMC is added in the ceramic molding to produce the products with good appearance, no cracks, defects or bubbles. CMC used in mosquito repellent incense industry, mainly as a binder role, enhance the folding resistance of mosquito repellent incense.
The paper industry is used for internal and external sizing and retention of fillers. The inner packing layer of CMC is made of plastic film bag, and the outer layer is packed with composite textile bags. Each bag is 25kg or 20kg net, stored in a cool, ventilated and dry place, and food grade CMC is stored separately from other chemicals.
