Super fine Calcium Carbonate made in our factory is a sort of drilling fluid material, which dissolves in acid its quality has been approved by CNPC. It's mostly used as heavy loader material of drilling fluid and completion brine which protect oil and gas layers as well as acid material to block leak. Its effect is by far superior to ordinary Calcium Carbonate powder. No other products can take the place of this one in the hi-tech of chemical industry, material, biological project, environmental protection and so on. At the same time, it also brings vitality to traditional industries such as paper making, ceramics, tuber, insulation material and forage, etc
