Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (organic and natural acid) carboxyl teams render the cellulose soluble and chemically reactive. The functional qualities of Fooding Carboxy Methyl Cellulose(CMC) count on the diploma of substitution of the cellulose composition (i.e., how numerous of the hydroxyl groups have taken portion in the substitution reaction), as effectively as the chain duration of the cellulose backbone framework and the degree of clustering of the carboxymethyl substituents.

Item efficiency and qualities:
CMC has a higher potential to control water reduction. In specific, PAC is a very powerful fluid reduction reducer at reduce dosages. You can handle the decline of h2o to a greater degree. It does not have an effect on other qualities of the mud.
The formed mud cake is of excellent top quality, strong and hard.
It has great temperature resistance and superb salt resistance. Below a certain salt concentration, it still has a good potential to lessen h2o reduction and sustain a specified rheology. In comparison to soluble in salt drinking water and soluble in drinking water, the viscosity rarely changes. Specifically ideal for offshore drilling and deep nicely specifications.
It can properly management the rheological houses of the mud. It has good non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilised as a cementing fluid to stop fluids from getting into pores and fractures. It is used as a fracturing fluid to control fluid decline into the nicely.
