In this paper, a new class of concrete high performance water reducer ( hpwr ) was designed from chemical classification of high performance wra, working principle and unit structure model of poly - carboxylate series wra. the comb - like copolymer structure of hpwr was " carboxylic group - ether link - ester link ". the synthetic chemical materials was polyethylene glycil, acrylic acid and methyl - metacrylic acid ester
本文從高性能減水劑的化學結構、作用機理以及聚羧酸類減水劑的單元結構模型出發，設計出國內所沒有的一類新型高性能減水劑? ? 「羧酸?醚鍵?酯鍵」為單元結構模型的梳型分子結構的減水劑共聚物，並確定了以聚乙二醇（ peg ）系列、丙烯酸（ aa ） 、甲基丙烯酸甲酯（ mma ）為合成該類減水劑的主要化學原料。 -
Abstract : in order to implement the goal of 2000 on total control and meet the requirement of discharging standard, daqing oilfield formulates the plan for industrial pollution sources to meet the standard and the plan for total control on discharging pollutants. a scheme on reducing the total amount of pollutants discharged by corporations is suggested. concrete measures are also suggested to treat chemical wastewater from chemical agent center factory and acrylic fibres engineering, as well as cyanide wastewater increased recently in the tertiary oil recovery engineering
