摘要POM是当今五大工程塑料之一，具有广阔的市场前景。本设计对POM的市场需求和用途进行了较全面的分析，并详细阐述了POM的性能和共混改性的方法。POM共混造粒生产线的工艺并不复杂，选择普遍使用的双螺杆挤出造粒的成型方法生产POM粒料，通过配方筛选、物料衡算、设备选型、工艺参数控制等过程对整个工艺流程作了较为详尽的阐述。并从降低成本、提高性能、应用前景等各方面考虑设计了较为合理的POM造粒生产配方和留有发展潜力的生产设备，计算其生产车间所需的各种生产设备和总投资成本，绘制出工艺流程图和生产车间设备平面布置图，对实际投资建设POM造粒生产车间的各个方面具有积极的指导作用。关键词：POM；共混造粒；改性；性能；生产线；工艺设计AbstractPOMistodayoneofthefivemajorengineeringplastics,ithasbroadmarketprospects.ThedesignonthemarketdemandanduseofPOMforamorecomprehensiveanalysis,anddetailtheperformanceofthePOMandtheblendmodifiedapproach.POMblendgranulationproductionlineprocessisnotcomplicated,selectthewidespreaduseofthetwin-screwextrusiongranulationmethodofproducingmoldingPOMaggregates,throughformulaselection,materialbalance,equipmentselection,processparameterscontrolthewholeprocessprocessmademoreindetail.Fromlowercosts,improveperformance,prospectsandotheraspectstoconsideramorerationaldesignofPOMgranulationformulationandleftpotentialproductionequipment,Calculateallthenecessaryworkshopequipmentandtotalinvestmentcosts,Drawaflowchartandworkshopequipment,floorplan,POMactualinvestmentandconstructionworkshopinallaspectsofgranulationpositiveguidance.Keywords:POM；granulationblend；modified；performance；productionline；processdesign目录摘要.......................................................................................................................................................................IABSTRACT............................................................................................................................................................II第一章概述.............................................................................................................................................................11.1聚甲醛简介.......................................................................................................................................11.2聚甲醛的应用和市场现状...............................................................................................................11.2.1聚甲醛材料的应用................................................................................................................11.2.2聚甲醛的市场现状................................................................................................................21.3聚甲醛的结构与性能.......................................................................................................................31.3.1聚甲醛的结构........................................................................................................................31.3.2聚甲醛的性能........................................................................................................................31.4聚甲醛的改性...................................................................................................................................71.5聚甲醛共混造粒生产线设计...........................................................................................................81.5.12500t/aPOM的合金化改性生产线简介..................
