Solid solution casting technology and device for heterogeneous anion-exchange membrane

Abstract

The invention relates to the technical field of solid solution casting of an anion-exchange membrane, and discloses a solid solution casting technology and device for a heterogeneous anion-exchange membrane. The device comprises a device body and a precise worm movably sleeved with the device body, the middle of the inner wall of the device body movably sleeves a forming roller, and the bottom ofthe forming roller is movably connected with a heterogeneous membrane; a cooling roller is movably sleeved with the device body, the front surface of the device body is fixedly connected with a worm wheel, an adjusting device is fixedly connected with the bottom of the worm wheel, and an annular adjusting plate is fixedly connected with the bottom of the adjusting device. According to the solid solution casting technology of the heterogeneous anion-exchange membrane, through mutual meshing between the precise worm and the worm wheel, a user can conveniently adjust the distance between a temperature control disc and the heterogeneous membrane, the outer surface of the heterogeneous membrane can be subjected to good heating and temperature control by the user, and the phenomenon that bubblesoccur on the surface of the heterogeneous membrane is avoided; the user can moderately control the temperature of the heterogeneous membrane, heating is uniform, and the stress of the heterogeneous membrane is reduced.

Description

technical field [0001] The invention relates to the technical field of solid solution casting of anion exchange membranes, in particular to a solid solution casting process and device of heterogeneous anion exchange membranes. Background technique [0002] Anion exchange membrane is a kind of high molecular polymer membrane containing basic active groups and has selective permeability to anions, also known as ion selective permeability membrane. Anion exchange membrane is composed of three parts: The main polymer chain of the polymer is the polymer matrix, the positively charged active group and the anion that can move freely on the active group. [0003] Anion exchange membrane has a very wide range of applications. It is an important part of separation devices, purification devices and electrochemical components. It plays a pivotal role in the fields of chlor-alkali industry, water treatment industry, heavy metal recovery, hydrometallurgy and electrochemical industry. The...

[0003] Anion exchange membrane has a very wide range of applications. It is an important part of separation devices, purification devices and electrochemical components. It plays a pivotal role in the fields of chlor-alkali industry, water treatment industry, heavy metal recovery, hydrometallurgy and electrochemical industry. The anion exchange membrane needs to be solid-solution casted before use. However, the existing solid-solution casting device and process do not have a good temperature control device and corresponding operation steps, which is not convenient for users to understand the heterogeneous solid-solution casting. The temperature control of the heterogeneous film will easily cause bubbles in the heterogeneous film, and it is not convenient to take out the stress of the heterogeneous film; and the existing solid solution casting device and process are not equipped with suitable control devices and corresponding operating steps, which may easily cause the heterogeneous film to detach or even tearing, so we propose a solid solution casting process and device for heterogeneous anion exchange membranes
