Carboxy Methyl Cellulose(CMC) is synthesized by the alkali-catalyzed response of cellulose with chloroacetic acid. The polar (natural acid) carboxyl groups 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 numerous of the hydroxyl teams have taken portion in the substitution response), as well as the chain length of the cellulose backbone framework and the diploma of clustering of the carboxymethyl substituents.

Item efficiency and attributes:
CMC has a high ability to handle h2o loss. In certain, PAC is a very effective fluid loss reducer at decrease dosages. You can control the loss of h2o to a greater amount. It does not impact other qualities of the mud.
The fashioned mud cake is of great top quality, strong and tough.
It has very good temperature resistance and outstanding salt resistance. Beneath a particular salt focus, it even now has a very good potential to minimize drinking water reduction and keep a certain rheology. In comparison to soluble in salt water and soluble in drinking water, the viscosity barely modifications. Particularly suitable for offshore drilling and deep nicely specifications.
It can well handle the rheological qualities of the mud. It has excellent non-Newtonian fluidity.
In addition, KELAIDE® CMC is utilised as a cementing fluid to prevent fluids from moving into pores and fractures. It is utilized as a fracturing fluid to control fluid decline into the properly.
Building grade CMC

|Purity||75-85% min||seventy five-ninety% min||80-ninety% min|
(in two.5% answer at 30 centigrade)
|300-five hundred mpa.s||four hundred-700 mpa.s||800-1200 mpa.s|
|Design||two% viscosity,mpa.s||PH||Reduction on drying,%||Purity%|
|KLD248||one hundred-two hundred||eight-12||≤40|
Be aware:we can create it in accordance to your demands.
1. “KELAIDE®” CMC is used to h2o-primarily based latex paint. It can fulfill the rheological properties of a specific movement below the action of brush or roller shear drive.
2. It can management viscosity and suspension.
3. CZPTly, CMC accounts for 1-3% in drinking water-dependent paints and coatings.
