Titanium anode for water electrolysis machine
Alkaline electrolyzers for water electrolysis machines have stable and good electrolysis effects, and are widely used in household electrolysis water machines, disinfection water machines and large water plants.
Titanium electrode is a key component in the water electrolysis machine, and the quality of the metal electrode directly affects the quality of the water machine. How to select electrodes should be reasonably selected according to different working properties. In the field of water treatment, metal electrodes must have the following basic requirements: (1) good electrical conductivity; (2) strong corrosion resistance; (3) mechanical strength and processing Good performance; (4) long working life; (5) good electrocatalytic performance, etc.
In the field of water treatment, especially in the process of electrolysis of water, there are various strong oxidizing substances in the water such as: O3, H2O2, HCLO, etc. in the process of generating acid and alkali ionized water, and the anode is often commutated, so It is necessary to use special functional electrodes. Titanium metal coated electrode is a pure titanium substrate coated with platinum group noble metal oxide with high electrocatalytic performance, strong oxidation resistance and good electrical conductivity, which is an insoluble anode. The properties of this anode are:
(1) Titanium has the characteristics of light specific gravity, good strength, corrosion resistance and good performance, especially the resistance to wet chlorine is unmatched by other metal materials. For example, when there is a small amount of chloride ions in the electrolysis of water, pitting corrosion will occur quickly on the stainless steel plate, which will shorten the life of the electrode, but titanium does not have these problems.
(2) Due to the addition of various platinum group precious metals in the coating, the current efficiency is high, the electrical conductivity is good, the electrocatalytic performance is good, the oxidation resistance is strong, the working life is long, and the energy is saved.
