1、Aiti-high temperature 150~160 ℃ ,16 hours it`s mud peformance keep constant.
2、Anti-electrolytes.In 2% Salt water ,it`s mud performance is better than FCLS (Ferrochrome lignosulfonate).
3、In the same mud ,it`s dilution performance is better than FCLS.
4、With excellent thinning performance and filtration control capacity and powerful anti-electrolytes. It is suitable to all kinds of muds.
Application:
Chrome lignosulfonate may be added into drilling fluids either in the form of solution or powder. PH:10.0~10.5,As a thinner 0.5~1.0%(W/V).
