Handing, Storage and Pre-treatment Instructions

Handling and storage:

Please store, handle, and process the membrane in a clean and dust-free environment.

When cutting the membrane, please use a new sharp knife or blade. When handling the membrane, please be sure to wear protective gloves and do not puncture, wrinkle, or scratch the membrane. Please keep all surfaces in contact with the membrane smooth and clean during handling, inspection, storage, pretreatment, and installation.

When stored for a long time, dry membrane should be stored in a sealed state, and wet membrane should be stored in a 3 wt% KHCO3 solution to avoid microbial contamination.

Pre-treatment Instructions:

The membrane is delivered in the form of chloride dry membrane, for optimal results, please remove the membrane from the backing film before using and immerse it in a large amount of excess 0.5M KOH aqueous solution. These exchanges can be carried out at ambient temperature or 80 ℃,the exchange effect will be better at 80℃ .

Please try to minimize the exposure time of the hydroxide form anion exchange membrane in the air, as CO in the air can affect the initial performance of the membrane. After exchanging to hydroxide form anion exchange membrane, in order to avoid changes in membrane size, please do not immerse the membrane in deionized water.

If it is necessary to clean the membrane , please use KHCO3 of similar concentration as the washing solution.
