Abstract

The invention provides a titanium electrode for a chlorine generator and a preparation method thereof, relating to a chlorine generator. The invention provides a titanium electrode with higher chlorine yield efficiency and longer service life for a chlorine generator and a preparation method thereof. The titanium electrode for the chlorine generator is provided with a titanium substrate on which a surface coating is arranged, wherein the surface coating is an oxide layer prepared from the following metals in percentage by mass: 0-70 percent of platinum, 10-80 percent of iridium and 20-90 percent of ruthenium. The preparation method comprises the following steps of: soaking the titanium substrate after surface treatment in water for later use; dissolving chloroplatinic acid, chloro-iridic acid and ruthenium trichloride in a mixed solution of isopropyl alcohol and hydrochloric acid to obtain a coating solution; and cooling, stirring and recoating the coating solution on the titanium substrate, drying, baking, recoating and baking to obtain the finished product.

Description

technical field [0001] The invention relates to a chlorine generator, in particular to a titanium electrode used in the chlorine generator and a preparation method thereof. Background technique [0002] With the continuous pollution of water resources on the earth and the continuous shortage of water resources, more and more recreational facilities such as swimming pools, living water halls or saunas are favored by people. In order to ensure the quality of water in these recreational facilities, it is usually necessary to The most common way to disinfect the water used is to use chlorine gas disinfection or a mixed disinfection method of chlorine gas and copper ions. In order to keep the available chlorine in water within a reasonable range of 1-3ppm, and at the same time avoid the local chlorine concentration caused by rapid chlorine production is too high and hurt people, the general practice is to put about 0.3% table salt in the circulating water, and then electrolyze th...
