sodium carboxymethyl cellulose

PRODUCT NAME: sodium carboxymethyl cellulose 

SYNONYMS:CMC

FORMULA:C6H7(OH)2OCH2COONa

CHEMICAL FAMILY: sodium carboxymethyl cellulose    

sodium carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.

Application in fresh water,sea water and saturated water
*small usage,high yield.
*Good anti-salt and anti-bacteria property,convenient to use.
*Reduce the fluid loss and improve the viscosity significantly.
Applications in drilling fluid
*Protect the wall of oil well,prevent mud flowing away and carry crumbs.
*Protect drilling bit and increase drilling speed.
*In low solid or none solid drilling fluid,it can reduce the fluid loss and thickness of the mud cake obviously.
*Strong inhibition effect to shale hydration.
Applications in fixing fluid
*Protect the wall of the oil well,stop the fluid entering into the pores or cracks.
*Control the fluid viscosity,heavy object suspension,and prevent fluid loss.
Instant products,used in severe environment,it will be more convenient and simpler,and it will be more effective in mud allocating.
PAC&CMC can be used in drilling fluid,fixing fluid and fracturing fluid.In drilling fluid,it works as viscosifier,filtration reducer,and rheology controller;in fixingfluid,it is used to control fluid viscosity,suspend heavy objects,andavoid fluid loss;in fracturing fluid,it is uesd to carry stuffing and avoid fluid loss.
