Product Introduction
We choose the high quality bentonite. After the purification, modification, processing, developed with the bentonite for drilling mud, which quality meet international standards of OCMA and the United States API grade.
Product Useage
Bentonite has a big expansion after meets water, has a good colloidal nature, can increase the viscosity of suspension in the drilling mud when used, can increase the lubrication of drilling, cleaning the debris during drilling, as well as for the rig-freeing agent. So which is widely used in complex geological formation drilling.
