Construction Grade Used in Paint and Coatings Sodium Carboxymethyl Cellulose CMC

Oil Drilling Grade CMC Carboxy Methyl Cellulose Chemical Adhesive HPMC CMC VAE HEC PVA HPS

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 useful qualities of Fooding Carboxy Methyl Cellulose(CMC) count on the degree of substitution of the cellulose framework (i.e., how numerous of the hydroxyl groups have taken component in the substitution response), as well as the chain size of the cellulose spine composition and the diploma of clustering of the carboxymethyl substituents.

Solution functionality and qualities:

CMC has a high capability to handle water reduction. In particular, PAC is a hugely successful fluid loss reducer at reduce dosages. You can control the reduction of water to a higher amount. It does not affect other homes of the mud.

The fashioned mud cake is of very good top quality, sturdy and difficult.

It has very good temperature resistance and outstanding salt resistance. Below a specified salt concentration, it even now has a very good potential to lessen drinking water reduction and preserve a specified rheology. When compared to soluble in salt drinking water and soluble in water, the viscosity hardly alterations. Specifically suitable for offshore drilling and deep well specifications.

It can well handle the rheological houses of the mud. It has very good non-Newtonian fluidity.

In addition, KELAIDE® CMC is employed as a cementing fluid to stop fluids from coming into pores and fractures. It is used as a fracturing fluid to control fluid reduction into the effectively.
