Description

A kind of preparation method of ozone electrolytic cell anode catalyst diaphragm plate
Technical field
The present invention relates to electrolytic preparation Ozone Water technical field more particularly to a kind of ozone electrolytic cell anode catalyst diaphragm plates Preparation method.
Background technology
Ozone is light blue gas, is a kind of extremely strong oxidant, by oxidation, inhibits the breeding and life of bacterium It is long, and lead to the death of bacterium, it is a kind of strong fungicide again.Ozone can be dissolved in water, and the Ozone Water of certain ozone concentration is same With extremely strong bactericidal effect.Ozone and Ozone Water can be sterilized and sterilized to food, drinking water, be disappeared to drinking water When malicious, in addition to the bacterium in water can be killed, it is further purified outside the impurity in water, moreover it is possible to increase the oxygen content in water.Ozone and All kinds of skin diseases that Ozone Water causes bacterium, bacterial inflammation, the diseases such as burn surfaces have certain curative effect.Ozone and Ozone Water also has many advantages, such as without side-effects, non-toxic, non-secondary pollution.Therefore, it is widely used in drinking water, food The fields such as processing, health care, chemical industry, environmental protection.
The method for preparing ozone has corona method and electrolysis, electrolysis to be better than corona method again can prepare high-concentrated ozone. Current electrolytic ozone generator, by electrolysis ozone generator, electrolysis ozone generator power supply, anode water tank, cathode water tank Composition.
Solid polymer electrolyte water electrolysis technology originates from the research of General Electric Company earliest, is USA space Plan exploitation low-temperature fuel cell was applied to the apparatus of oxygen supply aspect of spaceship and submarine later.Nowadays, solid polymerization Object electrolyte technology be widely used hydrogen-oxygen fuel cell, Organic Electrochemical Synthesis,
The fields such as the preparation of sensor, ozone.From in the eighties of last century middle and later periods, solid polymer electrolyte technology is more and more Use in the ozoniferous research of production.In the structure of solid polymer electrolyte electrolytic ozone generation, solid polymer ion For this solid electrolyte of exchange membrane instead of traditional liquid electrolyte, electrocatalytic particles are attached directly to solid polymer electrolytic On plasma membrane both sides, solid polymer electrolyte composite membrane is formed, this structure of composite membrane can increase the contact area of electrode reaction, The mass transfer velocity for greatly improving reactant is conducive to the separation of reaction product, and reaction is combined together with detaching, electrolysis is simplified The structure of device.Currently, anode catalyst diaphragm can use the materials such as platinum, glass-like carbon, stannic oxide and brown lead oxide, due to The product ozone of ozone generator has very strong corrosivity, so the film must be handled with the organic solution containing platinum, antimony, tin Plate makes its surface and inner passage form the conductive lumarith of one layer of platiniferous, antimony, tin.Such ozone generator anode Diaphragm plate structure and its manufacture craft have a disadvantage that:Since catalyst brown lead oxide particle is by polytetrafluoroethylene (PTFE) when being film-made piece It is bonded together, therefore the particle surface of the brown lead oxide just has polytetrafluoroethylene (PTFE), polytetrafluoroethylene (PTFE) is not catalyzed reaction Function, it reduces effective contact area of brown lead oxide particle, to make reaction efficiency decline, eventually leads to the production of ozone Raw rate declines.Even if difficult if carefully done upper corrosion protection processing ensure totality channel by described containing platinum, antimony, tin Conductive anticorrosion layer tightly covers.And diaphragm plate corrosion protection processing quality be influence ozone generator service life and efficiency it is decisive because Element.
Disadvantage mentioned above is the key limiting link of the efficiency and use cost that improve electrolysis type ozone generator, for smelly The preparation of oxygen electrolytic cell anode catalyst diaphragm plate, in the industry general technical solution mainly have mull technique, ion-exchange, electrochemistry Sedimentation etc., but these all do not break away from the processes such as bonding, plating, pressed-powder anode catalyst granules, and existing preparation Method can't ensure that ozone generator anode construction has high working efficiency and working life.
