CMC soluble in water can significantly increase the viscosity of solution, with thickening, dispersion, emulsification, suspension, protective colloid and other functions, and physiological harmless, so in the food, medicine, daily chemical, petroleum, paper, textile, construction and other fields of production has been widely used.
For oil, natural gas drilling, digging Wells and other projects
(1) CMC containing mud can make the shaft wall to form a thin and strong, low permeability filter cake, reduce the water loss.
Adding CMC in the mud, can make the drill to get a low initial shear, so that the mud is easy to release the gas wrapped in it, while the debris quickly abandoned in the mud pit.
(3) drilling mud and other suspended dispersion, has a certain period of existence, after adding CMC can make it stable and extend the existence period.
(4) CMC containing mud, rarely affected by mold, therefore, do not need to maintain a high PH value, do not need to use preservatives.
(5) CMC as a drilling mud washing fluid treatment agent, can resist a variety of soluble salt pollution.
6 CMC containing mud, good stability, even if the temperature above 150℃ can still reduce water loss.
CMC with high viscosity and high degree of substitution is suitable for mud with low density, CMC with low viscosity and high degree of substitution is suitable for mud with high density.
The choice of CMC shall be determined according to different conditions such as mud type, area and well depth.
For textile, printing and dyeing industry textile industry will CMC as sizing agent, for cotton, silk and wool, chemical fibers, blends and other strong yarn sizing;
CMC for paper industry can be used as paper smoothing agent and sizing agent in paper industry.
Adding 0.1% ~ 0.3% CMC to the pulp can enhance the paper's tensile strength by 40% ~ 50%, increase the compressive rupture degree by 50%, and increase the kneading property by 4 ~ 5 times.
(4)CMC can be used as dirt adsorbent in synthetic detergent;
The colloidal base of the toothpaste for the glycerine aqueous solution of the CMC of the toothpaste industry;
Pharmaceutical industry as thickener and emulsifier;
CMC aqueous solution after viscosification used for planktonic mineral processing.
Used in the ceramic industry can do the blank adhesive, plasticizer, glaze suspension agent, fixing agent, etc
