High-temperature resistant starch cellulose

High-temperature resistant starch cellulose

High-temperature resistant starch cellulose undergoes chemical modification to enhance water solubility and salt resistance. This involves increasing hydration groups in starch and simultaneously employing high temperature and solvents to physically modify the particle morphology of starch. These enhancements elevate the product's water solubility and salt resistance by introducing various modifying groups that confer resistance to high temperatures. As a result, its temperature resistance is boosted to over 130°C, with some models even usable at 150°C in the indoor evaluation system*. Furthermore, it ensures effective filtration loss reduction at low to medium temperatures, guaranteeing a broad operating temperature range.

CMC for oil

CMC for oil

Petroleum grade CMC serves as a water-soluble colloid in the drilling mud system, composing the drilling fluid. It exhibits a high water loss control capability, functioning as a filtrate reducer. At lower dosages, it effectively controls water loss while maintaining the mud's other properties. The mud cake formed is of high quality, firm, and tough. Moreover, CMC demonstrates excellent temperature resistance and superior salt resistance. It retains its ability to reduce water loss and maintain a certain rheological behavior even at specific salt concentrations. In both brine and aqueous solutions, the viscosity remains almost unchanged. This makes it particularly suitable for the demands of offshore drilling and deep wells.
