Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (natural acid) carboxyl teams render the cellulose soluble and chemically reactive. The practical homes of Fooding Carboxy Methyl Cellulose(CMC) depend on the degree of substitution of the cellulose composition (i.e., how a lot of of the hydroxyl teams have taken part in the substitution response), as nicely as the chain size of the cellulose spine structure and the degree of clustering of the carboxymethyl substituents.

Product functionality and qualities:
CMC has a substantial capacity to handle water decline. In specific, PAC is a very efficient fluid reduction reducer at reduce dosages. You can handle the decline of water to a higher degree. It does not have an effect on other houses of the mud.
The shaped mud cake is of very good high quality, robust and difficult.
It has excellent temperature resistance and excellent salt resistance. Below a particular salt focus, it nevertheless has a very good ability to decrease h2o loss and preserve a particular rheology. In comparison to soluble in salt drinking water and soluble in drinking water, the viscosity hardly adjustments. Notably suited for offshore drilling and deep effectively requirements.
It can effectively manage the rheological qualities of the mud. It has excellent non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilized as a cementing fluid to stop fluids from entering pores and fractures. It is utilized as a fracturing fluid to control fluid loss into the nicely.

Software:
1. “KELAIDE®” CMC is applied to drinking water-based latex paint. It can fulfill the rheological homes of a specified circulation underneath the motion of brush or roller shear force.
two. It can management viscosity and suspension.
3. CZPTly, CMC accounts for 1-three% in h2o-primarily based paints and coatings.
