CMC Chemical Adhesive Classification Agent Auxiliary

CMC Carboxy Methyl Cellulose (CMC) 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 practical homes of Fooding Carboxy Methyl Cellulose(CMC) count on the diploma of substitution of the cellulose composition (i.e., how many of the hydroxyl groups have taken element in the substitution reaction), as nicely as the chain size of the cellulose spine construction and the degree of clustering of the carboxymethyl substituents.

Product overall performance and qualities:

CMC has a large ability to management drinking water reduction. In distinct, PAC is a hugely effective fluid loss reducer at reduce dosages. You can control the decline of h2o to a higher stage. It does not have an effect on other homes of the mud.

The formed mud cake is of very good high quality, strong and tough.

It has great temperature resistance and exceptional salt resistance. Beneath a specified salt concentration, it nevertheless has a very good capability to lessen h2o decline and sustain a particular rheology. In contrast to soluble in salt drinking water and soluble in water, the viscosity rarely modifications. Particularly suitable for offshore drilling and deep properly requirements.

It can nicely manage the rheological houses of the mud. It has excellent non-Newtonian fluidity.

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

1. “KELAIDE®” CMC is applied to drinking water-based mostly latex paint. It can fulfill the rheological homes of a particular stream beneath the motion of brush or roller shear force.
two. It can handle viscosity and suspension.
three. CZPTly, CMC accounts for 1-three% in drinking water-dependent paints and coatings.
