Description:
CMC are the formation of high-viscosity colloids, solutions, adhesion, thickening, flow, emulsification and dispersion, shaping, water retention, protective colloids, film forming, acid resistance, salt resistance, suspension and other characteristics, and are physiologically harmless. Therefore, it is widely used in the production of food, medicine, daily chemical, petroleum, paper, textile, construction and other fields.
