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

Product functionality and traits:
CMC has a high capability to control drinking water decline. In certain, PAC is a very efficient fluid loss reducer at reduced dosages. You can control the reduction of drinking water to a larger stage. It does not impact other properties of the mud.
The formed mud cake is of excellent quality, robust and tough.
It has good temperature resistance and exceptional salt resistance. Below a particular salt concentration, it nevertheless has a very good capability to lessen water loss and sustain a particular rheology. When compared to soluble in salt water and soluble in water, the viscosity hardly alterations. Especially ideal for offshore drilling and deep properly needs.
It can properly management the rheological qualities of the mud. It has excellent non-Newtonian fluidity.
In addition, KELAIDE® CMC is used as a cementing fluid to avoid fluids from moving into pores and fractures. It is utilized as a fracturing fluid to manage fluid decline into the nicely.

Application:
1. “KELAIDE®” CMC is used to drinking water-dependent latex paint. It can fulfill the rheological houses of a specific stream underneath the motion of brush or roller shear drive.
two. It can management viscosity and suspension.
3. CZPTly, CMC accounts for 1-3% in h2o-primarily based paints and coatings.
