| Message: | oilfield thickener cationic polyacrylamide CPAMhe development of Boyuan water purification materials company in at the start of positioning in the oil field, the personnel of oil thickening agent has a unique research. More than and 10 years of experience in customer case to tell you: if the use of cationic polyacrylamide CPAM alone, although CPAM has good water solubility, adhesion ability is very strong, but poor resistance to high temperature, temperature higher than 70 DEG C when the effect is not ideal. Usually the cationic polyacrylamide CPAM as an ingredient for oil thickening agent configuration, the general choice of hydroxypropyl guar gum and cationic polyacrylamide composite oil as thickening agent used. By making full use of the polymer formed by these two kinds of polymer, the high temperature stability of the thickening agent in oil field can be improved, and the upper limit of the use temperature of the fracturing fluid can be improved.At this point, we use cationic polyacrylamide is no longer too high demand molecular weight, thereby reducing your cost. As long as the molecular weight is 3 million 500 thousand -400, the cationic polyacrylamide CPAM is used as the oil field thickening agent, it can achieve the effect of thickening agent. url:http://www.boyuanpam.com |
