青岛大学本科论文（设计）本科毕业论文(设计)题目：消泡剂复配及性能研究学院：化学化工与环境学院专业：轻化工程姓名：刘欢指导教师：张宾2014年6月4日青岛大学本科论文（设计）消泡剂复配及性能研究AStudyonPreparationandPerformanceofDefoamer摘要本论文研究了三种消泡剂ESD-C（有机硅类）、Z-25AS（聚醚类）、TL-56-1（有机硅类）的消泡、抑泡性能，对其进行了复配实验，考察了各组分对消泡效果的影响，确定了最佳的复配工艺，并且与消泡剂702进行试验对比。结果表明：配比为1:3的配比为Z-25AS（25%）和TL-56-1（75%）的复配消泡剂（0.05%）为最佳，在最大限度上减少消泡时间，时间为4s，抑泡时间为9s。该复配消泡剂消泡、抑泡能力较好，性能优越，稳定性好。关键字：消泡剂；硅油型消泡剂；聚醚型消泡剂；复配；稳定性青岛大学本科论文（设计）青岛大学本科论文（设计）AbstractInthisthesis,threedefoamersESD-C(silicone),Z-25AS(polyether),TL-56-1(silicone)ofdefoamingperformanceandtocarryoutcomplexwithexperimentstostudytheeffectsofanti-foamingeffectofeachcomponenttodeterminetheoptimalcomplexprocess,andthecomparisonwithexperiment702defoamers.Theresultsshowthat:theratioof1:3ratioofZ-25AS(25%)andTL-56-1(75%)ofcompounddefoamer(0.05%)isthebest,reducethemaximumextinctionsoaktime,timeof4s,defoamingtimeof9s.Thecomplexdefoamersdefoamingabilityisbetter,superiorperformanceandgoodstability.Keywords:defoamer;siliconedefoamer;polyetherdefoamer;complex;stabilty青岛大学本科论文（设计）目录1前言......................................................................11.1泡沫及其性能.........................................................21.1.1泡沫的形成......................................................21.1.2影响泡沫稳定性的因素............................................31.2消泡剂...............................................................41.2.1消泡剂物化特性..................................................41.2.2消泡剂的成分....................................................41.2.3消泡剂的分类消泡剂的种类很多，分类方法也有多种..................41.2.4消泡剂的应用....................................................61.2.5消泡剂的消泡机理................................................61.2.6消泡剂的发展概况................................................71.3聚醚改性硅油消泡剂...................................................81.3.1聚醚硅油消泡剂的反应原理........................................81.3.2聚醚硅油消泡剂的消泡机理........................................91.3.3复合型消泡剂....................................................91.4本课题研究的主要目的和意义...........................................92实验.....................................................................112.1实验仪器和试剂......................................................112.1.1实验试剂.......................................................112.1.2实验仪器......................................................112.2实验部分............................................................122.2.1十二烷基苯磺酸钠溶液（LAS）配制及起泡性测定...................122.2.2消泡剂固含量的测定............................................122.2.3单一消泡剂的消泡、抑泡性能测试................................122.2.4消泡剂复配及消泡抑泡性能测定......................................132.2.5稳定性测试........................................................133结果与分析...............................................................153.1十二烷基苯磺酸钠溶液（LAS）起泡性...................................
