Fluid Loss Control Additives for Oil Well Cementing
Product Description :
As the aggregated molecule chain of water soluble polymer can decrease the mud cake permeability of mud slurry, G311 introduces multi-functional groups that enhance the ability of anti high temperature and anti-salt.In addition, the fluid loss control additives is endowed with viscosity and suspension performance by means of molecular weight adjustment.
