Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (natural and organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The useful properties of Fooding Carboxy Methyl Cellulose(CMC) rely on the diploma of substitution of the cellulose structure (i.e., how many of the hydroxyl teams have taken element in the substitution reaction), as properly as the chain length of the cellulose spine structure and the degree of clustering of the carboxymethyl substituents.

Solution functionality and qualities:
CMC has a large potential to control drinking water decline. In distinct, PAC is a very powerful fluid loss reducer at reduced dosages. You can handle the decline of drinking water to a larger stage. It does not impact other houses of the mud.
The shaped mud cake is of great quality, strong and tough.
It has excellent temperature resistance and outstanding salt resistance. Beneath a particular salt concentration, it even now has a very good potential to reduce h2o reduction and maintain a certain rheology. Compared to soluble in salt drinking water and soluble in drinking water, the viscosity rarely changes. Specifically suitable for offshore drilling and deep properly demands.
It can properly manage the rheological properties of the mud. It has good non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilized as a cementing fluid to stop fluids from entering pores and fractures. It is employed as a fracturing fluid to manage fluid decline into the effectively.

Notice:we can produce it according to your requirements.
Application:
1. “KELAIDE®” CMC is utilized to water-based latex paint. It can fulfill the rheological homes of a specific movement below the motion of brush or roller shear drive.
2. It can manage viscosity and suspension.
three. CZPTly, CMC accounts for 1-three% in h2o-primarily based paints and coatings.
