年生产8000吨聚丙烯上水管挤出工艺设计

洛阳理工学院毕业设计（论文）I年生产8000吨聚丙烯上水管挤出工艺设计摘要文章介绍了聚丙烯的性能和聚丙烯管材的发展状况、特点、性能、分类，以及PP-R管材的用途、特点、性能、施工等，并结合聚丙烯管材的发展状况、特点和性能，以及PP-R管材的用途及性能要求等，做出了对PP-R管材挤出成型工艺的设计，同时也对生产规模效益等做出了一定的核算。其中工艺设计包括了对PP-R管材的原料配方制定和品质检验，加工设备的选用，设备安装及保养处理，工艺参数的制定，加工生产步骤与流程，产品品质检验，以及常见事故的处理等。结果表明，合适的加工工艺条件、成型设备以及有效的管理执行，能够保证PP-R管的品质质量及年产量，但是在短时间内不会取得很大的经济效益。否则，就必须扩大生产规模或减少厂区及设备投资，采取局部加工生产模式，充分有效地利用外部资源。关键词：聚丙烯PP-R，管材成型，工艺设计，设备，经济概算洛阳理工学院毕业设计（论文）IIdesignof8000tons/yearPolypropyleneunderwatertubebyexrutionprocessABSTRACTThispaperintroducestheperformanceofpolypropyleneandpolypropylenepipedevelopment,features,performance,classification,andtheuseofPP-Rpipe,features,performanceandconstruction,combinedwiththedevelopmentofpolypropylenepipes,characteristicsandperformance,andtheuseofPP-Rpipeandperformancerequirements,madeofPP-Rpipeextrusionprocessofdesign,butalsoontheeffectivenessoftheproductionscaletomakeacertainamountofaccounting.ProcessdesignwhichincludesaPP-Rpipeformulationdevelopmentandqualitytestingofrawmaterials,processing,equipmentselection,equipmentinstallationandmaintenancetreatment,thedevelopmentofprocessparameters,processingstepsandprocesses,productqualityinspection,andthehandlingofcommonaccidents.Theresultsshowthattheappropriateprocessingconditions,moldingequipment,andimplementationofeffectivemanagement,toensurethequalityofPP-Rpipequalityandoutput,butnotinashorttimemadegreateconomicbenefits.Otherwise,wemustexpandthescaleofproductionorreduceinvestmentinplantandequipmentandtakelocalprocessingmode,thefullandeffectiveuseofexternalresources.KEYWORDS:PolypropylenePP-R,TubeForming,ProcessDesign,Equipment,Economicestimates洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章聚丙烯及其管材...................................................................21.1概述......................................................................................21.2聚丙烯的性能.......................................................................21.4PP-R管材..............................................................................41.4.1PP-R管材的特点.........................................................41.4.2PP-R管主要用途.........................................................41.4.3PP-R管的选用标准.....................................................51.4.4PP-R管在安装施工及应用.........................................5第2章PP-R管的原料配方及品质检验..........................................72.1原料及性能...........................................................................72.2原料的配方...........................................................................82.2.1配方.............................................................................82.2.2配方设计说明.............................................................82.3原料性能品质检验...............................................................8第3章工艺计算及设备的选择与安装..........................................103.1物料的衡算.........................................................................103.2.1物料衡算的意义.......................................................103.2.2物料衡算方法...........................................................103.2.3物料衡算的计算.......................................................113.2热量衡算.............................................................................123.2.2热量衡算的计算.......................................................123.3生产设备的选择.................................................................133.3.1设备的选择原则.......................................................133.3.2设备的选择目的.......................................................133.3.3挤出机的选择...........................................................143.3.4辅机的选择................................................................153.4安装和调整.........................................................................18洛阳理工学院毕业设计（论文）IV第4章单螺杆挤出机生产PP-R工艺...........................................204.1工作原理.............................................................................204.1.1结构概述...................................................................204.2生产工艺流程.....................................................................204.2.1管材生产工艺流程...................................................204.3管材挤出参数......................................................................204.4首次开机准备工作.............................................................214.5生产操作步骤.....................................................................224.6产品品质检验.....................................................................234.6.1生产过程检验...........................................................234.6.2入库检验...................................................................244.6.3出货检验...................................................................244.7生产操作注意事项.............................................................24第5章设备的运转与保养.............................................................265.1设备的吊装运转注意事项.................................................265.2设备的保养.........................................................................26第6章常见事故及处理.............
