Product Description:

CMC appears to be white or light yellow powder, which is odorless and non-toxic. It is soluble in cold or hot water. When it solutes, some colloidal solution will appear, which is neutral or slightly alkaline. The important feature of CMC is that it can form colloid solution with high viscosity. Many factors influencing its viscosity are concentration, PH, temperature, substituted ratio and salts, etc.

Performance and Characteristics of Products:

CMC, as a kind of water-soluble gel in the drilling fluid system, constitutes drilling fluid. It is with high control ability of water loss. HV2 is a highly efficient fluid loss agent. When under the lower amount of water, you can control the water loss in a appropriate water level, without affecting the other performance of the mud. In addition, the quality of the mud cake it formates is good and it is with strong and tough property. Besides, its performance of salt resistance and temperature resistant is good. Under a certain concentration of salt, it can still have good filtration reduction ability and keep a certain rheology. Its viscosity changes little in the saline solution and aqueous solution. Adhesive is applicable for deep drilling. The rheology of slurry, with performance of good non-Newtonian fluid, can be easily controlled. When CMC was used as cementing fluid, it can prevent fluid from flowing into the rock formation and fracture. As a fracturing fluid, it can control the loss of fluid that flows into the well.
