Introduction of CMC
Sodium carboxymethyl celluose(CMC-Na)is a anion type linear macromole substances . Features of pure substance: white or ivory, insipidity, innocuity, fluidity, fibrous powder, freely soluble in cold or hot water to form transparent sticky solution, unique function.
Application of CMC:
1. Oil drilling grade CMC 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.
2. Detergent grade CMC, when used in liquid, paste detergent, acts as stabilizing agent and thickening agent; When used in detergent powder, CMC can effectively prevent washes from becoming contaminated after being washed by synthetic detergent.
3. CMC used in textile and dyeing industry as sizing agent and dying adjuvant to make stock limpidity and transparence. It is easy a good stabilizer of the stock and helps to form film. It is easy to desizing.
4.CMC in Food Industry:CMC is widely used in frozen desserts, protein food, beverages, icings, dressings, instant noodles, etc.
