Control Water Loss Sodium Carboxymethyl Cellulose 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 practical qualities of Fooding Carboxy Methyl Cellulose(CMC) count on the degree of substitution of the cellulose construction (i.e., how a lot of of the hydroxyl groups have taken part in the substitution reaction), as nicely as the chain size of the cellulose spine composition and the degree of clustering of the carboxymethyl substituents.

Solution overall performance and characteristics:

CMC has a high capacity to management drinking water reduction. In certain, PAC is a hugely efficient fluid reduction reducer at lower dosages. You can control the reduction of h2o to a higher stage. It does not impact other qualities of the mud.

The formed mud cake is of great quality, strong and difficult.

It has great temperature resistance and exceptional salt resistance. Below a specific salt focus, it even now has a great ability to reduce h2o loss and maintain a specified rheology. When compared to soluble in salt h2o and soluble in drinking water, the viscosity barely adjustments. Specifically ideal for offshore drilling and deep nicely needs.

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 stop fluids from entering pores and fractures. It is utilised as a fracturing fluid to handle fluid decline into the well.

Application:
one. “KELAIDE®” CMC is utilized to h2o-based latex paint. It can meet up with the rheological houses of a specified stream beneath the action of brush or roller shear force.
2. It can control viscosity and suspension.
three. CZPTly, CMC accounts for 1-3% in water-dependent paints and coatings.
