The temperature resistance, salt resistance, and shear resistance of the copolymer solution were evaluated. The results shown that the copolymer had excellent salt‐thickening ...

Dec 05, 2021 · Most of us already eat too much salt, with Brits for example having an average intake of 8.1g a day, compared with the recommended amount of 6g. Too much can lead to high blood pressure. Too much ...

Jan 31, 2021 · The cultivation of the extremely thermophilic archaeon Thermococcus stetteri in a dialysis membrane reactor was paralleled by the production of an extremely heat-stable proteinase(s). By applying preparative sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis, an SDS-resistant proteinase was purified 67-fold in one step with a yield of …

Sep 15, 2021 · Current PPGs neither remain hydrated nor retain polymer integrity at these temperatures. A unique high temperature-resistant hydrogel composition (HT-PPG) was developed with exceptional thermal stability for greater than 18 months in North Sea formation temperature (~130 °C) and formation water environments.

It offers an excellent balance of high strength and stiffness as well as good chemical resistance (Duan et al., 2006). Thermal degradation of commercial stabilized acetal measured at a constant heating rate of 10°C from room temperature to a high temperature, 800°C in nitrogen and air, is shown in Fig. 9.3. In an inert atmosphere, acetal ...

Jul 27, 2021 · The cross-linker systems of bisphenol-A/HMTA have four high-temperature resistant cross-linking points, and its performance was the best. Due to the introduction of ATBS and NVP groups on the polymer chain, the performance of gel system formed by the terpolymer L-1 was significantly more stable than that of formed by HPAM.

Aug 01, 2014 · chemical resistance and harmless; low cost and availability. Virtually no such coolants that would fully satisfy the requirements. The most affordable coolant - water. But as the freezing temperature is high (0° C), then the water is used only in air conditioning systems and processes at positive temperatures.

Oct 24, 2017 · The developed copolymer has a highly branching skeleton and can resist temperature up to 100 °C. And then, a gelant with high temperature resistance and good shear resistance can be formed by mixing a certain proportion of the developed copolymer and polyethyleneimine (PEI).

Thus, these double network systems showed excellent salt resistance with the non-covalent interactions and physical entanglements, and the viscosity of the allyl alcohol polymer/polyacrylamide system did not drop but increase. The viscosity in high salinity could increase nearly 40 % compared with the initial situation.
