CH310LHigh Temperature Cement Retarder
The CH310L high temperature cement retarder appears inthe form of brownish black liquid and in the smell of slightly pungent odor. Itcomes with a density of 1.30±0.05g/cm3, a freezing point of -10℃ or lower, and can be completely dissolved in water. The pH value of the hightemperature cement retarderis within the range between 5.0 and 7.0. Our high temperature cement retarder is made up of 25% sodiumglucoseheptylate with theCAS number of 31138-65-5, and 15% graft copolymers between starch and acrylamide, as well as 5% Erthylenebis tetraphosphonic acid with the CAS number of1429-50-1. The rest composition of the high temperature cement retarder is 45% water coming withthe CAS number of 7732-18-5.
Generally speaking, the dosage of this high temperature cement retarder is 0.5-3.0% by weight of cement (BWOC) andthe recommend amount is 1.0% BWOC.The following form table clearly shows the composition information andtechnical performance of the cement slurry with our high temperature cement retarder.
