PE-PCC is a mixture of high-charged inorganic polymer chains and inorganic salts. It is easily soluble in water and has low corrosion. It is suitable for drilling fluid systems and water-based drilling fluids/drilling cuttings.
Features:Fast floc formation and fast settling
Low corrosiveness
Little increase in salt content in treated water
Strong temperature adaptability
PE-FIFPE-PIF is an inorganic polymer flocculant, suitable for polymer water-based drilling fluids/drill cuttings, with good flocculation effect and fast reaction speed, which can effectively improve the solid-liquid separation efficiency.
Features:Good flocculation effect,fast reaction speed
No harmful heavy metal ions, safe and reliable
Suitable for pH range of 4-11, the best pH range is 6-9
PE-XN21SPE-XN21S is a water-soluble inorganic polymer. It has a high degree of electrical neutralization and bridging effect on colloids and particles in water through a structured high-charged polymer chain, and can strongly remove colloid particles and heavy metals ion, suitable for the treatment of well completion fluid waste.
Features:Fast solid-liquid separation
Good effluent quality; Safe and environmental friendly
PE-ZN22SPE-ZN22S molecular chain contains a certain number of polar groups, which can absorb solid particles suspended in water to form large flocs and accelerate flocculation.
Features:Fast solid-liquid separation
Simple and safe operation
Environmental friendly
Non-corrosive and non-irritative
