Carboxymethyl Cellulose Adhesive Carboxy Methyl Cellulose Sodium CMC
Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (natural and organic acid) carboxyl teams render the cellulose soluble and chemically reactive. The useful houses of Fooding Carboxy Methyl Cellulose(CMC) rely on the degree of substitution of the cellulose framework (i.e., how several of the hydroxyl teams have taken portion in the substitution response), as nicely as the chain size of the cellulose backbone structure and the diploma of clustering of the carboxymethyl substituents.

Merchandise efficiency and qualities:
CMC has a higher potential to manage water reduction. In certain, PAC is a highly powerful fluid reduction reducer at lower dosages. You can manage the decline of drinking water to a greater stage. It does not have an effect on other homes of the mud.
The formed mud cake is of excellent good quality, robust and tough.
It has good temperature resistance and outstanding salt resistance. Under a particular salt concentration, it nonetheless has a excellent capability to minimize h2o reduction and maintain a particular rheology. Compared to soluble in salt h2o and soluble in water, the viscosity rarely changes. Especially suited for offshore drilling and deep effectively needs.
It can effectively manage the rheological qualities of the mud. It has very good non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilized as a cementing fluid to stop fluids from getting into pores and fractures. It is utilized as a fracturing fluid to control fluid reduction into the nicely.

Application:
1. “KELAIDE®” CMC is used to drinking water-primarily based latex paint. It can meet up with the rheological houses of a specified movement beneath the action of brush or roller shear drive.
2. It can manage viscosity and suspension.
three. CZPTly, CMC accounts for 1-three% in water-dependent paints and coatings.
