摘　　要：测定了不同温度下E - 4 4环氧树脂胶液的粘度和密度。用 φ50mm离心萃取器考察了E - 4 4环氧树脂与苯的体积比对相夹带的影响 ,并研究了各操作条件 (转速、流比和总流量 )对净化效果的影响。用 φ2 30mm离心萃取器进行了工业规模现场试验 ,试验结果表明 ,加入苯溶剂时 ,净化后E - 4 4环氧树脂中无机氯含量小于 5mg L。不加入苯溶剂时 ,净化后E - 4 4环氧树脂胶液中无机氯的含量小于 1 0 0mgBoth the density and the viscosity of E-44 epoxy resin solution are measured at different temperature.The effect of the volume ratio of E-44 epoxy resin to benzene on phase entrainment is investigated with φ 50mm centrifugal extraactor.The relation between operating factors(rotor speed the flow rate and the flow ratio)and the purifying effect is studied with φ 50mm centrifugal extractor too.The plant test is carried out with φ 230mm centrifugal extrator.When benzene was added into E-44 epoxy resin,the content of chlorine in the E-44 epoxy resin is less than 5mg/L after purification.Without adding bezene,the content of chlorine in the E-44 epoxy resin is less than 100mg/L after purification.
