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 (natural and organic acid) carboxyl teams render the cellulose soluble and chemically reactive. The functional houses of Fooding Carboxy Methyl Cellulose(CMC) depend on the diploma of substitution of the cellulose construction (i.e., how a lot of of the hydroxyl groups have taken element in the substitution response), as properly as the chain length of the cellulose spine structure and the degree of clustering of the carboxymethyl substituents.

Product functionality and qualities:
CMC has a large potential to management h2o decline. In specific, PAC is a hugely powerful fluid decline reducer at lower dosages. You can control the loss of drinking water to a higher degree. It does not influence other homes of the mud.
The fashioned mud cake is of good high quality, powerful and challenging.
It has very good temperature resistance and outstanding salt resistance. Beneath a specific salt concentration, it still has a very good capacity to lessen water loss and preserve a specific rheology. Compared to soluble in salt h2o and soluble in water, the viscosity barely changes. Particularly suitable for offshore drilling and deep well needs.
It can well manage the rheological properties of the mud. It has great non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilized as a cementing fluid to prevent fluids from moving into pores and fractures. It is utilised as a fracturing fluid to management fluid loss into the well.

Software:
1. “KELAIDE®” CMC is utilized to h2o-based latex paint. It can fulfill the rheological qualities of a specified movement below the action of brush or roller shear drive.
two. It can manage viscosity and suspension.
3. CZPTly, CMC accounts for 1-3% in water-dependent paints and coatings.
