I2020 届北京理工大学珠海学院本科生毕业设计年产 2 万吨 PVF 的生产工艺设计年产 2 万吨 PVF 的生产工艺设计摘 要聚氟乙烯（PVF）是一种热塑性树脂，英文名称为 poly（vinyl fluoride）。它是在中国后期开发的，产量相对较小，目前主要用于制造薄膜和涂料。此设计基于特定的浙江材料有限公司 PVF 树脂复合材料车间的技术设计项目。本设计采用改进的悬浮聚合法直接合成聚氟乙烯，采用分批反应的方法通过二次蒸馏分离出产物，从而获得高质量的产物。该方法具有温和的操作条件，相对较高的产率和相对成熟的方法，因此是理想的生产方法。该设计主要包括产品介绍，项目背景，设计准则，工艺生产计划，流程设计，物料与能量两方面的平平衡，重要设施的布局和规划，工作场所布局设计，环境保护，安全设计和三种废物。诸如机加工的设计还包括与项目相关的设计图，例如工艺流程图和车间设备布局。 关键词：PVF;工业化生产;工艺设计; II2020 届北京理工大学珠海学院本科生毕业设计III2020 届北京理工大学珠海学院本科生毕业设计Production process design of PVF with an annual output of 20000 tonsAbstract Polyvinyl fluoride (PVF) is a thermoplastic resin, the English name is poly (vinyl fluoride). It was developed in late China and its output is relatively small. Currently it is mainly used to manufacture films and coatings. This design is based on the specific technical design project of the PVF resin composite workshop of Zhejiang Materials Co., Ltd. This design uses an improved suspension polymerization method to directly synthesize polyvinyl fluoride, and uses a batch reaction method to separate the product by secondary distillation to obtain a high-quality product. The method has some mild operating conditions, relatively high yield and relatively mature method, so it is an ideal production method. The design mainly includes product introduction, project background, design criteria, process production plan, process design, balance between materials and energy, layout and planning of impo...
