Adhesive Carboxymethyl Cellulose Powder CMC

    Carboxy Methyl Cellulose (CMC) is synthesized via the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups make the cellulose water-soluble and chemically reactive. The functional characteristics of Food-grade Carboxy Methyl Cellulose (CMC) are determined by the substitution degree of the cellulose structure (i.e., the quantity of hydroxyl groups involved in the substitution reaction), along with the chain length of the cellulose backbone structure and the aggregation degree of the carboxymethyl substituents.

    CMC has a high ability to control water loss. In particular, PAC is a highly effective fluid loss reducer at lower dosages. You can control the loss of water to a higher level. It does not affect other properties of the mud.

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

    It has good temperature resistance and excellent salt resistance. Under a certain salt concentration, it still has a good ability to reduce water loss and maintain a certain rheology. Compared to soluble in salt water and soluble in water, the viscosity hardly changes. Particularly suitable for offshore drilling and deep well requirements.

    It can well control the rheological properties of the mud. It has good non-Newtonian fluidity.
