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.
