Modified XCD Polymer

High temperature-resistant rheological modifier DT-130 is a kind of high quality xanthan gum, which is produced by the optimum strain improvement fermentation process. It has many prominent properties, such as thickening, emulsifying, thickening suspension, suspension, salt-resistant, temperature-resistant, acid-resistant, alkali-resistant, anti-shear, outstanding high viscosity and water-soluble. It also shows unique pseudoplastic rheological characteristics, excellent stability to temperature and PH. The most satisfied is its good compatibility, safety and ecology. In the case of constant temperature, DT-130 solution can reversibly change over sol and gel with the changing mechanical force. Therefore it is a highly efficient thickener, simultaneously with other thickening forming stable thickened systems, and maintain the original rheology. Normal xanthan gum can only be stable at 121 ℃, while DT-130 also has a higher temperature resistance. It is stable at 130 ℃, with good rheology. Therefore, DT-130 can be used in areas such as drilling and EOR high temperature environments.
