Sodium Carboxymethyl Cellulose for Drilling

Carboxymethyl Cellulose Adhesive Carboxy Methyl Cellulose Sodium CMC

Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The useful houses of Fooding Carboxy Methyl Cellulose(CMC) rely on the degree of substitution of the cellulose construction (i.e., how several of the hydroxyl groups have taken portion in the substitution response), as well as the chain length of the cellulose backbone construction and the diploma of clustering of the carboxymethyl substituents.

Product efficiency and traits:

CMC has a large capacity to management drinking water reduction. In particular, PAC is a highly efficient fluid decline reducer at reduced dosages. You can handle the reduction of h2o to a higher degree. It does not influence other qualities of the mud.
The formed mud cake is of great quality, strong and difficult.
It has good temperature resistance and superb salt resistance. Underneath a particular salt concentration, it nonetheless has a great potential to decrease h2o loss and keep a particular rheology. In comparison to soluble in salt drinking water and soluble in h2o, the viscosity barely modifications. Notably suited for offshore drilling and deep nicely requirements.
It can well handle the rheological houses of the mud. It has great non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilised as a cementing fluid to avert fluids from getting into pores and fractures. It is utilized as a fracturing fluid to manage fluid decline into the properly.

1. “KELAIDE®” CMC is used to h2o-based latex paint. It can satisfy the rheological homes of a specific stream underneath the motion of brush or roller shear power.
two. It can control viscosity and suspension.
3. CZPTly, CMC accounts for one-three% in h2o-based mostly paints and coatings.
