Product features: Bentonite has strong dilatability after meeting water, has good colloidal properties, which can make the viscosity of suspension increase. When using in drilling mud, can increase the lubricity of drilling tools, cleaning the rock waste produced in the drilling process.
Product application: widely used in drilling construction of strata with complex geological structure, preventing the occurrence of accidents in the hole.
