摘要
聚乙烯醇是一种性能优良、绿色环保型高分子材料，对其改性可以衍生出众多不同性能的产品，具有广阔的应用市场。以某聚乙烯醇双螺杆挤出改性过程为例，从气相燃爆风险及粉尘燃爆风险两方面入手，对其生产运行过程中可能存在的燃爆危险进行分析，并针对导致危险的原因在工艺设计中采取相应的措施，以提高系统的本质安全性。
Abstract
Polyvinyl alcohol is a kind of polymer material with excellent performance and environmentally friendliness.Many kinds of products with different properties can be derived through modifying polyvinyl alcohol,which have a broad application market.Taking a polyvinyl alcohol twin-screw extrusion modification process as an example,the possible explosion hazard during production and operation is analyzed from the gas phase explosion risk and dust explosion risk aspects.Corresponding measures to solve the problem causing risks are taken in the process design to improve the intrinsic safety of the system.
