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 theohmic 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.
Better current density distribution.
Elasticity can long last & durable performances in the life.
Longer membrane life and
lower cell voltage with more or less the same caustic faraday efficiency
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.
Installation Summary
Anode remeshing is like normal recoating procedure.
Original cathode mesh is maintained and used as current distribution . no need of coating.
Mattress is fixed on current distributor by resistant welding.
Possible to retrofit cathode package on site.
Flynet is installed on mattress. Welding is not used for Flynet.
