Embodiment Construction

[0006] The present invention is implemented by the following methods

[0007] The ion exchange membrane is divided into styrene sulfonic acid type cation exchange membrane, also known as cation exchange membrane, and styrene quaternary ammonium type anion exchange membrane, also known as anion exchange membrane. When in use, the two are used in pairs, assembled into an electrodialyzer, and desalination and ion purification are performed under the action of a two-pole current. The manufacturing process of the two membranes is the same, but the ion exchange resin used is different. The cation exchange membrane uses styrene sulfonic acid type cation exchange resin, while the anion exchange membrane uses styrene quaternary ammonium type anion exchange resin. In order to improve its water treatment capacity, the ion exchange resin used to make the ion membrane must be crushed before use, and its fineness is generally around 200 mesh. In order to form a film, other components must...

Abstract

This invention relates to heterophase ions exchange film with water process function and bacterial inhibition function, which can be used in electrodialysis assembly and ion tree resin matching and for sea water and salt water desalt and to process boiler water, distilled water and purified water with bacterial inhibition function.

Description

technical field [0001] The invention relates to the field of preparation of water treatment materials, in particular to an antibacterial heterogeneous ion exchange membrane with water treatment function and antibacterial function and a preparation method thereof. Background technique [0002] Water is an important natural resource. In order to meet the physiological needs of an adult, about 2 liters of water are needed per day. To maintain cleanliness, cook food, household heating and air conditioning, etc., each person consumes 2,850 liters of water per day, while industrial water It is even more difficult to count the large amount, and there is still a large amount of farmland that needs to be irrigated. [0003] Although there is enough water in the ocean to cover the entire earth, it can be as deep as 2 miles. But most of the water that people need can only be met by fresh water, and the pure water on the earth is decreasing year by year, and there is a serious problem ...
