CG610SAMPS Quadripolymer CementFluid Loss Additive
The CG610S AMPS quadripolymer cement fluid loss additive can bedivided into the CG610S-T dry and water mixed type and the CG610S-D dry mixedtype. The CG610S-T AMPS quadripolymercement fluid loss additive is an off white power with a bulk density of0.80±0.10 and 100% water solubility. As a grey powder, the CG610S-D AMPS quadripolymer cement fluid loss additive has a bulkdensity of 0.90±0.10 and is completely soluble in water. Both of these twocement additives remain no more than 15% when filtered by a 0.315mm sieve. TheCG610S-D is not easy to damp and agglomerate. Under appropriate storageconditions, the shelf life can be extended with no limit. However, the CG610S-Tis easy to agglomerate after long time storage. Although agglomeration doesn’taffect the product performance, it will decrease the mobility and watersolubility of the AMPS quadripolymercement fluid loss additive. In addition, both of them adopt 50% AMPS copolymer,with the CAS number of 40623-75-4. However, the CG610S-D is still composed of50% slag/silica flour, and the CG610S-T adopts 50% sodium chloride, with theCAS number of 7647-14-5. In order to effectively control fluid loss of cement,the dosage of this AMPS quadripolymer cement fluid loss additive isgenerally 1.6-4.0% (BWOC), and the recommend amount is 1.8% (BWOC).
