Oil Drilling Grade CMC Carboxy Methyl Cellulose Chemical Adhesive HPMC CMC VAE HEC PVA HPS
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 purposeful properties of Fooding Carboxy Methyl Cellulose(CMC) count on the degree of substitution of the cellulose construction (i.e., how numerous of the hydroxyl groups have taken component in the substitution response), as effectively as the chain size of the cellulose spine framework and the diploma of clustering of the carboxymethyl substituents.

Item efficiency and traits:
CMC has a high capability to control water reduction. In distinct, PAC is a extremely effective fluid reduction reducer at reduce dosages. You can manage the decline of h2o to a greater amount. It does not have an effect on other houses of the mud.
The formed mud cake is of great quality, sturdy and difficult.
It has excellent temperature resistance and superb salt resistance. Under a particular salt concentration, it still has a good capability to reduce drinking water loss and preserve a certain rheology. In comparison to soluble in salt water and soluble in drinking water, the viscosity barely alterations. Notably suitable for offshore drilling and deep properly requirements.
It can nicely control the rheological homes of the mud. It has very good non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilised as a cementing fluid to prevent fluids from coming into pores and fractures. It is utilized as a fracturing fluid to control fluid loss into the effectively.

Application:
one. “KELAIDE®” CMC is applied to h2o-based mostly latex paint. It can satisfy the rheological qualities of a particular circulation below the action of brush or roller shear pressure.
two. It can control viscosity and suspension.
three. CZPTly, CMC accounts for 1-three% in h2o-dependent paints and coatings.
