Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The practical properties of Fooding Carboxy Methyl Cellulose(CMC) rely on the diploma of substitution of the cellulose construction (i.e., how several of the hydroxyl teams have taken part in the substitution response), as well as the chain duration of the cellulose spine construction and the diploma of clustering of the carboxymethyl substituents.

Solution efficiency and attributes:
CMC has a higher potential to control drinking water loss. In distinct, PAC is a extremely efficient fluid decline reducer at reduce dosages. You can manage the reduction of drinking water to a greater degree. It does not influence other properties of the mud.
The formed mud cake is of good top quality, robust and tough.
It has good temperature resistance and outstanding salt resistance. Under a particular salt focus, it even now has a great ability to reduce drinking water loss and preserve a particular rheology. In contrast to soluble in salt h2o and soluble in water, the viscosity barely adjustments. Specifically appropriate for offshore drilling and deep properly demands.
It can effectively handle the rheological houses of the mud. It has good non-Newtonian fluidity.
In addition, KELAIDE® CMC is used as a cementing fluid to avert fluids from getting into pores and fractures. It is employed as a fracturing fluid to manage fluid reduction into the properly.

Application:
1. “KELAIDE®” CMC is used to water-based mostly latex paint. It can fulfill the rheological properties of a certain movement underneath the action of brush or roller shear force.
two. It can management viscosity and suspension.
three. CZPTly, CMC accounts for one-three% in drinking water-primarily based paints and coatings.
