Sodium CMC CAS 9004-32-4 High Viscosity CMC Sodium Carboxymethyl Cellulose CMC

Oil Drilling Grade CMC Carboxy Methyl Cellulose Chemical Adhesive HPMC CMC VAE HEC PVA HPS

Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (natural acid) carboxyl groups render the cellulose soluble and chemically reactive. The practical qualities of Fooding Carboxy Methyl Cellulose(CMC) rely on the degree of substitution of the cellulose composition (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as nicely as the chain length of the cellulose backbone structure and the diploma of clustering of the carboxymethyl substituents.

Merchandise performance and qualities:

CMC has a higher potential to management h2o reduction. In specific, PAC is a highly powerful fluid decline reducer at reduced dosages. You can manage the reduction of drinking water to a greater degree. It does not influence other houses of the mud.

The fashioned mud cake is of good high quality, sturdy and hard.

It has very good temperature resistance and excellent salt resistance. Underneath a specific salt concentration, it even now has a good capacity to lessen drinking water loss and preserve a specific rheology. When compared to soluble in salt drinking water and soluble in h2o, the viscosity rarely adjustments. Particularly suited for offshore drilling and deep nicely demands.

It can well control the rheological homes of the mud. It has very good non-Newtonian fluidity.

In addition, KELAIDE® CMC is employed as a cementing fluid to stop fluids from getting into pores and fractures. It is employed as a fracturing fluid to control fluid decline into the effectively.

one. “KELAIDE®” CMC is utilized to h2o-based mostly latex paint. It can meet the rheological houses of a specific stream beneath the action of brush or roller shear power.
2. It can management viscosity and suspension.
3. CZPTly, CMC accounts for 1-3% in h2o-dependent paints and coatings.
