Natural cellulose is the most widely distributed and the most abundant polysaccharide in nature.At present, the modification technology of cellulose mainly focuses on etherification and esterification.Carboxymethylation is a kind of etherification technique.Carboxymethyl cellulose (CMC) is obtained after carboxymethylation of cellulose. Its aqueous solution has the functions of thickening, film formation, adhesion, water retention, colloid protection, emulsification and suspension. It is widely used in petroleum, food, medicine, textile and paper industry and is one of the most important cellulose ether.
For Food industry:
Food grade for dairy drinks and seasonings, CMC can thicken, stabilize and improve taste. In addition, CMC is also used in ice cream, bread, cake, biscuit, instant noodle and fast paste food for product molding, taste improvement, water retaining and tenacity strengthening.
For Detergent Industry:
Effectively prevent washes from becoming contaminated after being washed by synthetic detergent. Also make washing liquid more viscous and the effect of washing more stable.
For Oil drillling Industry:
Widely used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency.
