Manufacturing technique
Reaction mechanism
Finished product can be refered as CMC.
Molecular formula: C6H7O2(OH)3
CMC solubility
CMC is natural hydrophilic substance. SMC powder swells and dissolves in water.
Methods to accelerate dissolving speed:
Slowly adding of CMC under stirring
Adding CMC under heating condition but not for super high temperature, better no higher than 60℃
For mixing use with other material, solid mixing first and then dissolve
Disperse in organic solvent soluble with water, as, ethyl alcohol, glycerol and propylene glycol
Packaging Types
We can provide 25kg bagor as per customers' requirements.
1. CMC has function of thickening, emulsifying, suspension, water retention, tenacity strengthening, puffing and preservation in food. In food, it can improve taste, promote product level and quality and prolong storage life.
2. We have more requirements on daily living equipments with development of living standard. Toothpaste is necessities of life. And many functional type and health care type new products have been developed, which has high and new requirement on CMC.
3. More stable than natural thickener; Fine liquidity and even dyeing property
4. Effect of CMC in oil field, Mud with CMC makes wall of a well thin and solid, Add CMC in mud to make drilling machine get low shearing force, Mud with CMC almost is not influenced by mould, Mud with CMC has fine stability
5. CMC product is main adhesive of water-based negative electrode materials and is widely used by battery manufacturers. Better adhesive for large battery capacity, long cycle life and low internal resistance. Therefore we improve production technique to develop battery exclusive used products.
6. CMC is used as excipient, plasticizer and fortifier of preform body in ceramic industry. Used in ground coat, face coat, printed coat, Application of CMC in ceramic preform
7. Thickening, dispersing and emulsifying effect, High degree of substitution and fine transparency performance
8. In several procedures, as, pigment coating, addition in pulp, surface sizing, Excellent water-retaining property, dispersing property and shear thinning property
