CMC Carboxymethyl cellulose sodium
Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (natural and organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The useful properties of Fooding Carboxy Methyl Cellulose(CMC) depend on the diploma of substitution of the cellulose construction (i.e., how numerous of the hydroxyl teams have taken component in the substitution response), as effectively as the chain length of the cellulose backbone construction and the degree of clustering of the carboxymethyl substituents.

Item performance and traits:
CMC has a substantial capacity to management water loss. In particular, PAC is a highly effective fluid decline reducer at decrease dosages. You can handle the reduction of water to a increased degree. It does not affect other properties of the mud.
The fashioned mud cake is of excellent high quality, sturdy and hard.
It has excellent temperature resistance and exceptional salt resistance. Under a particular salt focus, it still has a very good ability to lessen drinking water decline and sustain a particular rheology. When compared to soluble in salt drinking water and soluble in h2o, the viscosity hardly adjustments. Notably ideal for offshore drilling and deep well requirements.
It can properly handle the rheological homes of the mud. It has great non-Newtonian fluidity.
In addition, KELAIDE® CMC is employed as a cementing fluid to avoid fluids from moving into pores and fractures. It is utilised as a fracturing fluid to manage fluid reduction into the effectively.
