Oil Drilling Grade 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 reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The useful houses of Fooding Carboxy Methyl Cellulose(CMC) depend on the diploma of substitution of the cellulose composition (i.e., how a lot of of the hydroxyl groups have taken part in the substitution reaction), as nicely as the chain length of the cellulose spine construction and the diploma of clustering of the carboxymethyl substituents.

Item performance and attributes:

CMC has a substantial capability to control water loss. In specific, PAC is a highly efficient fluid decline reducer at reduce dosages. You can control the decline of water to a higher degree. It does not affect other homes of the mud.

The shaped mud cake is of great top quality, strong and hard.

It has excellent temperature resistance and excellent salt resistance. Below a specified salt focus, it nevertheless has a excellent potential to decrease drinking water decline and preserve a specified rheology. In comparison to soluble in salt h2o and soluble in water, the viscosity rarely adjustments. Notably suitable for offshore drilling and deep properly requirements.

It can well control the rheological houses of the mud. It has excellent non-Newtonian fluidity.

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

1. “KELAIDE®” CMC is used to drinking water-based latex paint. It can meet up with the rheological homes of a specific movement under the action of brush or roller shear power.
two. It can control viscosity and suspension.
three. CZPTly, CMC accounts for one-3% in h2o-based paints and coatings.
