Sodium Carboxymethyl Cellulose -CMC
1.CAS No.: 9004-32-4
Other Names: Sodium Carboxymethyl Cellulose
MF: C6H7O2(OH)2OCH2COONA
Appearance: powder
Purity: 99
2.Description:
CMC LV is a low viscosity sodium carboxymethylcellulose ,designed to reduce API filtration rate with minimum increase in viscosity in water based drilling fluids.
Packaging Detail: Packaging: in muliwall kraft paper bags of 25Kg, 50Lbs or 25Lbs net each with P.E liner inside.
3.CMC Oil Drilling:
1）high degree of substitution, good uniformity of substitution .
2）high transparency, viscosity and water loss can be controlled .
3）suitable for fresh water, sea water, saturated brine slurry .
4） stabilize soft soil structure, prevent collapse of wall of a well .
5）can improve mud-making volum, reduce filteration loss .
6）has excellent performance in drilling of oil .
