沈阳建筑大学毕业论文沈阳建筑大学毕业论文毕业论文题目泡沫陶瓷的制备及其性能表征的研究学院专业班级材料化学09-1班学生姓名姜峰性别男指导教师赵苏职称教授2013年6月10日沈阳建筑大学毕业论文摘要泡沫陶瓷材料的发展始于20世纪70年代，是一种具有高温特性的多孔材料。由于它具有气孔率高、比表面积大、抗热震、耐高温、耐化学腐蚀及良好的机械强度和过滤吸附性能，可广泛应用于热交换材料，布气材料，汽车尾气装置，净化冶金工业过滤熔融态金属，热能回收，轻工喷涂行业，工业污水处理等。本文以以贝壳粉为造孔剂，研制氧化铝泡沫陶瓷。通过对制品体积密度、显气孔率、吸水率等性能的测试，分析了贝壳粉掺量对泡沫陶瓷性能的影响。实验表明，适量添加贝壳粉作造孔剂，可制得性能较好的氧化铝泡沫陶瓷。在本实验研究条件下，当贝壳粉掺量为10%时，可制得外观良好、吸水率为29.92%，体积密度1.16g/cm3，显气孔率33.78%的氧化铝泡沫陶瓷制品。关键词：泡沫陶瓷;贝壳粉;制备;性能沈阳建筑大学毕业论文AbstractDevelopmentoffoamceramicsbeganinthenineteenseventies,isakindofhightemperaturepropertiesofporousmaterials.Becauseithasahighporosity,chemicalcorrosionresistanceandgoodmechanicalstrengthandadsorptionfiltrationperformanceoflargespecificsurfacearea,thermalshockresistance,hightemperatureresistance,andcanbewidelyappliedtotheheatexchangematerials,clothmaterial,automobileexhaustpurificationdevice,filteringmoltenmetallurgicalindustrialmetal,heatrecovery,lightindustryandcoatingindustry,industrialwastewaterprocessingetc..Foamceramiccanbemadebyaddingshellpowderasfoamingagenttoceramicrawmaterials.Theinfluenceoftheshellpowderonthequalityoffoamceramicwasanalyzedthroughtheirrelatedpropertiessuchasbulkdensity,openporeporosity,waterabsorptionandsoon.Itisfoundthatbyaddingpropershellpowder,thebetterqualityfoamceramiccanbemade.Ontheconditionofthisexperiment,whentheshellpowdercontentis10%,canbeobtainedwithgoodappearance,waterabsorptionratewas29.92%,1.16g/cm3,bulkdensity,apparentporosityofaluminafoamceramicproducts33.78%.Keywords:thefoamceramic;theflyash;preparation;research沈阳建筑大学毕业论文1目录第一章绪论...............................................................................................................11.1泡沫陶瓷...........................................................................................................11.2历史...................................................................................................................11.3现状...................................................................................错误!未定义书签。1.3.1概况.........................................................................错误!未定义书签。1.3.2泡沫陶瓷国内外技术水平.....................................错误!未定义书签。1.4意义...................................................................................................................41.4.1..................................................................................错误!未定义书签。1.4.2..................................................................................................................71.4.3..................................................................................错误!未定义书签。1.4.4..................................................................................错误!未定义书签。1.4.5..................................................................................错误!未定义书签。1.5性能...................................................................................................................71.5.1气孔率.....................................................................................................71.5.2抗弯强度.................................................................................................71.5.3泡沫玻璃作绿化用保水材料...............................................................151.6............................................................................................错误!未定义书签。1.6.1..................................................................................错误!未定义书签。1.6.2..............................................................................................................161.6.3..................................................................................错误!未定义书签。1.6.4..................................................................................错误!未定义书签。第二章实验部分.......................................................................................................172.1实验目的.........................................................................................................182.2实验药品及仪器.............................................................................................182.3试验方法.........................................................................................................182.4实验过程.........................................................................................................19沈阳建筑大学毕业论文22.4.1..................................................................................错误!未定义书签。2.4.2..................................................................................错误!未定义书签。第三章实验结果及分析...........................................................................................203.1实验结果.........................................................................................................203.2数据处理.........................................................................................................213.3实验结果分析...................................................................错误!未定义书签。3.3.1..................................................................................错误!未定义书签。3.3.2.......................................
