The ion exchange membrane for electrolysis is produced by the unique tape casting process with appropriate molecular weight and ion exchange capacity of perfluorosulfonic acid resin to form homogeneous membrane with uniform thickness,the Ion-Exchange Membrane has the characteristics of high tensile strength, isotropic, high electrical conductivity, good chemical properties, and so on.
Electrolysis is the process of passing an electric current through an electrolytic solution or a molten electrolyte (also called electrolyte) to cause a redox reaction on the cathode and anode. An electrochemical cell can undergo an electrolytic process when a DC voltage is applied.
Electrolysis is a process that uses chemical reactions that occur at the interface between an electrode that is an electronic conductor and an electrolyte that is an ionic conductor to synthesize chemicals and to process high-purity materials. When the current is applied, the cations in the electrolyte move to the cathode, which absorbs electrons and undergoes a reduction effect to generate new substances; the anions in the electrolyte move to the anode, which emits electrons and undergoes oxidation to generate new substances. For example electrolytic melting of sodium chloride.
The electrolysis process is performed in an electrolytic cell. The electrolytic cell is composed of two electrodes, cation and anode, which are respectively immersed in a solution containing positive and negative ions. The current flows into the negative electrode (cathode), the positively charged positive ions in the solution migrate to the cathode and combine with the electrons to become neutral elements or molecules; the negatively charged negative ions migrate to the other electrode (anode) and give Out of the electron, it becomes a neutral element or molecule.
The device that converts electrical energy into chemical energy is called an electrolytic cell. A process of passing a direct current through an electrolyte solution or melt to cause a chemical reaction of the electrolyte on an electrode to prepare a desired product. The electrolysis process must be equipped with electrolyte, electrolytic cell, DC power supply system, analysis control system and product separation and recovery device. The electrolytic process should use lower cost raw materials as much as possible, improve the selectivity of the reaction, reduce the generation of by-products, shorten the production process, and facilitate product recovery and purification. The electrolytic process has been widely used in non-ferrous metal smelting, chlor-alkali and inorganic salt production, and the organic chemical industry.
