lron chromium salf
Application:
Lron chromium lignin sulphonate is a kind of deep well diluent,which can be widely used in fresh water,sea water,and calciumtreated mud.
Product performance:
Lron chromium salt is a filtration-reducing agent,which can reducing the mud water loss.it has strong antsalt,anti-calciun effect.which has some ability of lnhibit mud-making capacity and stabilize shale.
Using method:
Added iron chromium saltdirectly to the mud in conjiuction with Na0H was added to make the PH value＞9,in order to receive the lower viscosity and shear strength as well as water loss good results.if bubbles appear in the iron-chromium sale mud,you can add defoaming agents..
