Polyanionic cellulose (PAC)
PAC, divided viscosity (HV) and low viscosity (LV) are two types - can be used as thickeners, rheology control agents, binders, stabilizers, protective colloid, suspending and SAR; (PAC HV, PAC LV, CMC HV, CMC LV)
In the oil industry, PAC is a good drilling mud additives and completion fluids formulated material, high mud, salt anti-calcium good performance. Freshwater mud, sea mud and saturated brine mud, PAC is a good amount of fluid loss treatment agent, and has good lift capacity and high temperature viscosity (150 ℃) capability. Suitable for the preparation of fresh water, sea water and saturated brine completion fluids and calcium-emphasis can be formulated into various densities of completion fluids, completion fluids and can make a certain viscosity and low fluid loss.
I produced the "YUYU" brand high viscosity and low viscosity PAC OCMA in line with European standards and the US API standards.
Specifications: viscosity (HV) and low viscosity (LV)
Grade: Ordinary level and excellent grades
