1.Chrome free lignosulfonate work as excellent thinning performance and filtration control capacity ,the mud performance of fresh water is better than salt water mud.
2.Chrome free lignosulfonate can resist high temperature of 150℃,it can cooperate with other admixture agent.
3.Good emulsifying effect in mud.
1.Free-Chrome thinner may be added into drilling fluids either in the form of solution or powder. PH:10.0~10.5
2.As thinner ,fresh water mud 1.0%(W/V), salt water mud 2.0%(W/V).
25kg net weight. With PE film bag inside and paper-plastic complex bag outside.
