Can bentonite increase viscosity? This problem is one of the key factors related to the use of bentonite. When we use bentonite for drilling operations, we can add polyacrylamide to bentonite most of the time to improve the viscosity and use effect of bentonite.

But it should be noted that polyacrylamide can not be directly added to bentonite, because in general, polyacrylamide can not react with bentonite, so it can not increase the viscosity of bentonite. Most of the time, polyacrylamide needs to be prepared into 0.1% aqueous solution, and then mixed with bentonite. Bentonite can be directly added to polyacrylamide solution. If bentonite has been prepared into slurry, polyacrylamide solution can be added.

Not all types of polyacrylamide can be used to increase the viscosity of bentonite, because polyacrylamide is a flocculant. Therefore, in order to avoid the coagulation phenomenon between polyacrylamide and bentonite, we mostly choose polyacrylamide with hydrolysis degree or non-ionic polyacrylamide, and then mix it with bentonite at high speed.

Can bentonite increase viscosity? From some practice and experimental data, appropriate polyacrylamide and reasonable configuration method can improve the viscosity of bentonite, and also can get a reasonable scheme through small-scale test before configuration. Through the type and dosage of polyacrylamide and configuration method, the viscosity of bentonite can be increased.
