Polyacrylamide (PAM) is an important chemical additive in the petroleum industry, mainly used in the following aspects:1. Improve crude oil recovery (tertiary oil recovery)Mechanism of action: Injecting polyacrylamide solution into the oil layer can significantly increase the viscosity of the inject

Sodium gluconate can significantly delay the initial and final setting time of concrete. When the dosage is below 0.15%, the logarithm of the initial setting time is directly proportional to the amount of mix, that is, the amount of mix is ​​doubled. The initial setting time is delayed by 10 times, which extends the working time from a few hours to several days without compromising the strength. This is an important advantage especially on hot days and when the time required to place is long.

With the continuous acceleration of industrialization and rapid economic growth, refractory materials, as key industrial raw materials, play a vital role in the high-temperature industry. In the process of widespread use and mass production of refractory materials, the benefits brought by the high-t

In the field of modern building materials, sodium tripolyphosphate is also one of the important admixtures to improve the performance of concrete. The main function of sodium tripolyphosphate is to reduce the amount of water used during construction by improving the fluidity of concrete. Its unique
