3.Use method and notice
It can be used directly into the drilling fluid, but the added speed is not too fast. Freshwater drilling fluid system, the recommended initial dosage is 0.5% ~ 1.5%; Brine drilling fluid system, for the first time recommended dosage is 1.5% ~ 3.0%. Specific dosage determined in accordance with drilling fluid . A large number of nitrates on the shaker prevail.
4.Transportation and storage
The product is packaged in three-on-one bag with the net weight 25kg.The inaccuracy is±0.25kg. It should be put into dried storage room lest it is polluted or dampened. Pay attention to anti-dampness,anti-exposure and bag breakage during the transportation.
