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

Solution efficiency and characteristics:
CMC has a high capability to handle water decline. In particular, PAC is a extremely efficient fluid loss reducer at decrease dosages. You can management the decline of drinking water to a increased level. It does not influence other properties of the mud.
The formed mud cake is of great high quality, powerful and challenging.
It has great temperature resistance and excellent salt resistance. Under a particular salt concentration, it nonetheless has a great potential to reduce drinking water decline and preserve a specific rheology. When compared to soluble in salt drinking water and soluble in drinking water, the viscosity hardly modifications. Particularly suited for offshore drilling and deep well needs.
It can effectively management the rheological properties of the mud. It has excellent non-Newtonian fluidity.
In addition, KELAIDE® CMC is employed as a cementing fluid to avert fluids from entering pores and fractures. It is utilised as a fracturing fluid to management fluid reduction into the well.
