Chemical process of making asbastose diaphragm of sodium hydroxide manufacture?

A Sri Lankan university student, Thiwanka has asked this question from me.




The diaphragm is made of a porous mixture of asbestos and polymers. It must be a permeable asbestos based diaphragm is used to separate the anode products from the cathode products.

There are two types of diaphragm cells

1. Mesh type - mesh type diaphragm cell anode ( box type anode )
2. Plate type ( perforated ) - perforated plate diaphragem cell ( electrolyzer ) anodes
