Carboxymethylcellulose, Brand Name : cmc

we offer carboxymethylcellulose.
description:carboxymethylcellulose sodium is a semisynthetic water-soluble polymer in which ch2cooh groups are substituted on the glucose units of the cellulose chain through an ether linkage.cmc-na is a kind of cellulose ether with anion contour’s high molecular structure. it has no smell, no taste and no toxicity. the white to off-white powder and graininess can be easily melt in water and become colloidal solution, but it can’t melt in alcohol, ether, acetone and other organic solvent.
usage:carboxymethylcellulose sodium can increase the viscosity of solution, it is considered potentially harmless biologically to the human. therefore it widely used in food-making, detergent, papermaking, oil-drilling, textile, dyeing, ceramics, construction, paint, welding, battery, medicine, toothpaste, cosmetics, etc.⑴ the drilling, well-digging of petroleum and natural gas.
the cmc slurry can form a filter cake on the wall of well to lower the water loss of well;
cmc can help slurry releasing the gas and discharging the broken matter;
cmc can prolong the existing period of drilling fluid;
cmc drilling fluid is seldom infected by mould, the high ph value and antiseptic are unnecessary;
cmc can be used as flush fluid to reduce the pollutation of soluble-salts;
cmc slurry can work well in 150℃;
⑵ used as sizing agent of cotton, silk, wool, chemical fiber and blending textile.⑶ used as smoothing agent and sizing agent of papermaking, 0.1%～0.3% of cmc can increase 40%50% of intension, 50% of compression breakage resistance and 4 to 5 times of flexibility.⑷ used as dirty adsorbent of detergent, the gel base of toothpaste, thickening agent and emulsifier ofmedicine, or used as mine selection.⑸ used as adhesive, plasticizer, suspending agent , color fixative of material.⑹ used in construction for water-keeping and reinforcement.⑺ used as thickening agent, adhesive and shaping agent of jam, juice, fruit juice, cake and ice cream.
