High Quality Sodium Carboxymethyl Cellulose CMC is a kind of important cellulose ether and a good water-soluble polyanionic compound obtained from chemically modified natural fibers, soluble in cold water. It has unusual and extremely valuable comprehensive physical and chemical properties such as emulsifiablity, dispersion, solid dispersion, non-perishability, physiological harmlessness, etc., and is a kind of widely-used natural polymer derivatives.
The largest use of Sodium Carboxymethyl Cellulose is to compound soap and synthetic detergent, add about 1% ofCarboxymethyl Cellulose in the heavy cleaner, to prevent the dirt washed out reprecipitating on the fabric. Secondly, Croscarmellose Sodium is used as suspension stabilizer of drilling fluid in petroleum industry
. Used in oil and gas drilling, sink well and other projects, in oil drilling, Sodium Carboxymethyl Cellulose can be used as suspension stabilizer and water-retaining agent to protect oil well. Generally, the dosage is 2.3 t for shallow well, 5.6 t for deep well.
