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, tobacco, toothpaste, cosmetics, etc.
⑴ The drilling, well-digging of petroleum and natural gas.
1 The CMC slurry can form a filter cake on the wall of well to lower the water loss of well;
2 CMC can help slurry releasing the gas and discharging the broken matter;
3 CMC can prolong the existing period of drilling fluid;
4 CMC drilling fluid is seldom infected by mould, the high PH value and antiseptic are unnecessary;
5 CMC can be used as flush fluid to reduce the pollutation of soluble-salts;
6 CMC slurry can work well in **0℃;
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 *0%
*0% of intension, *0% 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 of
medicine, 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.
