Carboxymethylcellulose sodium salt

General

Sodium carboxymethyl cellulose (CMC) is a cellulose derivative, an ionic cellulose gum, and owing to its unique thickening, suspending, adhesion, and water retention properties, is widely used in various industrial fields

Specifications

Charactaristics

● Water soluble
● No odor or taste anionic polymer
● Improved binding properties
● Excellent thickening property
● Compatible with most hydrocolloids application

Applications

1)The drilling mud with CMC can form thin and solid shaft wall as well as filter cake with low permeability, and thus can reduce the hole shrinkage and collapse phenomena resulting from water loss of mud.
2)The mud with the addition of sodium carboxymethylcellulose is seldom affected by mycete, so it can be stored for relatively long without maintaining high pH value or the use of preservatives.
3)The mud with CMC has favorable liquidity, stability as well as thixotropy, so even at the temperature above 150℃, it still can reduce water loss. In addition, it helps to prevent a lot of water entering into oil layer and thus increase the production of crude oil.

4)CMC-LV can be used as the thickening agent and gelatinizing agent of tertiary oil recovery in the oilfield and has obvious effects on stable oil production and production increase in oilfield fracturing, water shut-off and profile control, and acidizing operation
