Chlor Alkali Anode & Equipment's f

Purpose

Reducing the gap between anode and cathode. In zero gap technology, both anode and cathode surfaces are in contact with the membrane, i.e. electrode gap equals to membrane thickness.  Achieving uniform current distribution the original anode and cathode mesh are not fully flat; this is creating some non-uniformity in the current distribution. The elastic element can adjust its thickness following meshes profile, so the gap between anode and cathode is kept uniform.

Concept

Zero Gap Technology totally removes the ohmic drop related to ionic movement through the Catholyte gap, by installation of a package of…

Cathode screen which is used as current collector.

A fine cathode screen shifts up to gently touch the membrane.

In between them, durable elastic element is inserted, to transport electrons by contact from the current collector to the fine cathode screen, and capable of compensating for mechanical tolerances with no harm for the membrane.

Objective

Elastic element fills the gap between cathode & membrane.

Reduction in cell voltage & Low hydrogen evolution voltage cathode.

Suitable for electricity conduct from current distributor to activated cathode.

No high pressure on membrane.

Elasticity can long last & durable performances in the life.

Components

Nickel Mattress: assuring a perfect “zero-gap” condition between cathode mesh and membrane.

Activated Nickel Flynet: fine woven mesh, activated with a MMO coating specific for “zero-gap” applications, positioned on top of the Nickel Mattress.
