Application
1.CMC for Oil Drilling: It can increase viscosity and  reduce water loss in drilling fluid, cementing fluid and fracturing fluid. It also plays the role of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate.
*Usage: add to mud directly or glue solution preparation. 
*Addition: 0.1-0.3% in fresh water mud; 0.5-0.8% in salt water mud.
2.CMC Ceramic Grade:  It's used for ceramic embryo, glazing pulp and colored glaze in ceramic industry.
*Addition:0.03%-0.2% used in ceramic embryo; 0.05-0.2% used in glazing pulp; 1.4-4.0% used in colored glaze.
3.CMC Paper Grade: It's used in making pulp so as to improve the retention rate and increase humidity and strength; when used in surface sizing, CMC can improve internal adhesion, decrease printing dust and enhance printing quality as molding reagent. In paper coating, CMC also helps the dispersion and fluidity of paint, improves appearance of paper and smoothness, upgrades optical performance and printing adaptability.
*Addition: 0.3-1.5%.
4.CMC Construction Grade: Used in construction to improve water retention and strength.
5.CMC for other industries:As coagulant, water retaining, thickener and binder, it's also used in paint, carpet gum, mosquito coil incense, tobacco, electric welding, textile, battery, printing and others.
