CMC HV

• 

KimaCell® CMC HVsodium carboxymethyl cellulose is generally believed that when the degree of substitution is around 0.6-0.7, the emulsifying performance is better, and with the increase of the degree of substitution, other properties are improved accordingly. When the degree of substitution is greater than 0.8, its acid resistance and salt resistance are significantly enhanced. . The main indicators to measure the quality of cmc degree of substitution(DS) and purity. Generally, the properties of CMC are different if the DS is different; the higher the degree of substitution, the stronger the solubility, and the better the transparency and stability of the solution. According to reports, the transparency of CMC is better when the degree of substitution is 0.7-1.2, and the viscosity of its aqueous solution is the largest when the pH value is 6-9.

Specification of CMC HV

Application of CMC HV

KimaCell® CMC HV sodium carboxymethyl cellulose is As a water-soluble colloid in the drilling mud system, CMC has a high ability to control water loss. Adding a small amount of CMC can control the water at a high level. In addition, it has good temperature resistance and salt resistance. It can still have a good ability to reduce water loss and maintain a certain rheology. When dissolved in brine or water, the viscosity hardly changes, especially suitable for the requirements of offshore drilling and deep wells. CMC-containing mud can make the well wall form a thin, hard, low-permeability filter cake, reducing water loss. After adding CMC to the mud, the drilling rig can get a low initial shear force, so that the mud can easily release the gas wrapped in it, and at the same time, the debris can be quickly discarded in the mud pit. Drilling mud, like other suspension dispersions, has a certain shelf life. Adding CMC can make it stable and extend the shelf life.
