CG510S-PAMPS Terpolymer CementFluid Loss Additive
The CG510S-PAMPS terpolymer cementfluid loss additive adopts 98% AMPS copolymer with the CAS registry number of40623-75-4 as its main ingredient, which ensures the high purity of this cementadditive. This fluid lossadditive can effectively control the fluid loss in cement just with a generaldosage of 0.8-1.8% by weight of cement and a recommended amount of 0.9% BWOC.In addition, the AMPS terpolymercement fluid loss additive is completely soluble in cold water, so it can bemixed with other dry contents and water. The bulk density of this white powder is 0.50±0.10 g/cm3 and the relative density ofthe slightly pungent cement fluid loss additive achieves 1.65±0.05, with waterequal to 1. In addition, the pH value of the AMPS terpolymer cement fluid loss additive in 5% aqueoussolution is 5.0±1.0. By the way, afterfiltered with a 0.315mm sieve, the fluid loss additive remains 15% or less.
