Superiority

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.

 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 150℃;

 used as sizing agent of cotton, silk, wool, chemical fiber and blending textile.

 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.

 used as dirty adsorbent of detergent, the gel base of toothpaste, thickening agent and emulsifier of

medicine, or used as mine selection.

 used as adhesive, plasticizer, suspending agent , color fixative of material.

 used in construction for water-keeping and reinforcement.

 used as thickening agent, adhesive and shaping agent of jam, juice, fruit juice, cake and ice cream.
