Carboxymethyl Cellulose Oil Well Drilling CMC

Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (organic acid) carboxyl teams render the cellulose soluble and chemically reactive. The practical qualities of Fooding Carboxy Methyl Cellulose(CMC) rely on the diploma of substitution of the cellulose structure (i.e., how several of the hydroxyl teams have taken component in the substitution response), as nicely as the chain size of the cellulose backbone framework and the degree of clustering of the carboxymethyl substituents.

Product efficiency and attributes:

CMC has a substantial ability to management h2o loss. In particular, PAC is a very efficient fluid loss reducer at lower dosages. You can control the decline of water to a increased amount. It does not affect other homes of the mud.

The shaped mud cake is of good good quality, powerful and challenging.

It has great temperature resistance and exceptional salt resistance. Underneath a specified salt focus, it even now has a very good capability to minimize h2o reduction and keep a specific rheology. When compared to soluble in salt water and soluble in h2o, the viscosity rarely adjustments. Specifically suited for offshore drilling and deep properly demands.

It can well management the rheological qualities of the mud. It has good non-Newtonian fluidity.

In addition, KELAIDE® CMC is employed as a cementing fluid to avoid fluids from coming into pores and fractures. It is utilised as a fracturing fluid to manage fluid reduction into the nicely.

Notice:we can produce it in accordance to your needs.

1. “KELAIDE®” CMC is used to drinking water-primarily based latex paint. It can satisfy the rheological houses of a particular movement beneath the action of brush or roller shear pressure.
2. It can manage viscosity and suspension.
3. CZPTly, CMC accounts for one-three% in water-dependent paints and coatings.
