Quick-soluable Fluid Loss Control Additive
Product Description :
G30S is copolymerized by the AMPS, low molecular weight amides and so on. It dissolved in water quickly, therefore it can shorten on-site preparation of drugs dissolution time. Polymer molecular chains by reducing bundle concentrating slurry cake permeability. It reduce the slurry cake permeability by the aggregation of high polymer molecular chain.
