【摘要】 研究了以双辛基酚聚氧乙烯醚和双烷基苯双磺酸盐这两类双子表面活性剂为主的金属清洗剂的清洗性能。结果表明,这种含有阴/非双子表面活性剂的金属清洗液具有较高的表面活性,阴/非双子表面活性剂之间存在良好的协同效应。清洗液和润滑油之间具有较低的瞬间界面张力,能将含油铝片的液-固接触角大幅度减小。在超声波作用下3 m in左右含双子表面活性剂的清洗液的去油率可达100%,腐蚀率几乎为零,最佳清洗温度在40℃左右。更多还原

【Abstract】 The property of metal detergent consists of two kinds of gemini surfactants(dialkylphenyl bisulphonate and bisphenolic polyoxyethylene ether) was studied for cleaning the smeary surface of aluminium.The results show that gemini surfactants has high surface activities and super synergistic effect.Moreover,the transient interfacial tension between oil and cleaner is low and the contact angle between liquid and solid decreases greatly.The deoil rate can reach 100% in three minutes under the ultrasonic actions,and the corrosion rate is almost zero,and the optimum deoil temperature is about 40 ℃.更多还原
