Carboxy Methyl Cellulose Sodium CMC for Textile
Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (natural and organic acid) carboxyl teams render the cellulose soluble and chemically reactive. The useful homes of Fooding Carboxy Methyl Cellulose(CMC) count on the diploma of substitution of the cellulose composition (i.e., how several of the hydroxyl groups have taken portion in the substitution reaction), as properly as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.

Solution performance and attributes:
CMC has a high capacity to control h2o reduction. In particular, PAC is a highly successful fluid decline reducer at decrease dosages. You can handle the loss of h2o to a higher stage. It does not have an effect on other properties of the mud.
The fashioned mud cake is of great high quality, powerful and challenging.
It has great temperature resistance and superb salt resistance. Underneath a specific salt focus, it nonetheless has a good potential to minimize water reduction and preserve a specific rheology. In comparison to soluble in salt water and soluble in drinking water, the viscosity hardly modifications. Particularly suited for offshore drilling and deep nicely demands.
It can nicely management the rheological houses of the mud. It has great non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilized as a cementing fluid to avoid fluids from getting into pores and fractures. It is used as a fracturing fluid to manage fluid loss into the well.

Application:
one. “KELAIDE®” CMC is utilized to h2o-based latex paint. It can satisfy the rheological homes of a particular movement underneath the motion of brush or roller shear force.
2. It can control viscosity and suspension.
three. CZPTly, CMC accounts for one-three% in water-dependent paints and coatings.
