5. There are two methods for industrial production of sodium hydroxide: causticization and electrolysis.

6. Causticization method is divided into soda causticization method and natural caustic causticization method according to different raw materials.

7. Electrolysis method can be divided into diaphragm electrolysis method and ion exchange membrane method.
