Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (natural and organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The functional properties of Fooding Carboxy Methyl Cellulose(CMC) depend on the diploma of substitution of the cellulose composition (i.e., how a lot of of the hydroxyl groups have taken component in the substitution reaction), as nicely as the chain length of the cellulose backbone framework and the degree of clustering of the carboxymethyl substituents.

Solution efficiency and attributes:
CMC has a large capability to control water loss. In specific, PAC is a very powerful fluid decline reducer at lower dosages. You can control the reduction of water to a larger level. It does not influence other homes of the mud.
The shaped mud cake is of very good quality, strong and hard.
It has good temperature resistance and exceptional salt resistance. Beneath a particular salt concentration, it still has a very good potential to minimize water reduction and maintain a specific rheology. When compared to soluble in salt water and soluble in h2o, the viscosity hardly changes. Especially appropriate for offshore drilling and deep nicely specifications.
It can effectively manage the rheological houses of the mud. It has very good non-Newtonian fluidity.
In addition, KELAIDE® CMC is employed as a cementing fluid to prevent fluids from entering pores and fractures. It is utilised as a fracturing fluid to management fluid loss into the well.

Note:we can produce it according to your specifications.
1. “KELAIDE®” CMC is applied to drinking water-dependent latex paint. It can meet the rheological qualities of a particular circulation under the action of brush or roller shear force.
2. It can management viscosity and suspension.
3. CZPTly, CMC accounts for one-3% in h2o-based paints and coatings.
