High-levelness electrode preparation process

Abstract

The invention discloses a high-levelness electrode preparation process. The high-levelness electrode preparation process comprises the high-temperature annealing step, specifically, an electrode matrix subjected to sand blasting and grinding is taken and subjected to high-temperature annealing, the electrode matrix is placed in a high-temperature furnace with the temperature being 600-1200 DEG C,subjected to heat preservation for 1-4 h and then cooled to the room temperature, and the levelness of the electrode matrix is controlled to be 0.08-0.15 mm. High-temperature annealing and leveling are carried out on the electrode matrix after the electrode matrix is subjected to sand blasting and grinding, so that levelness of the electrode matrix and the uniformity of a coating are ensured, an electrode set is more convenient to install accordingly, electrode spacing stability is ensured, and accordingly the effects that the electrolysis efficiency is improved, the heating amount of an electrolysis bath is reduced and the running energy consumption is reduced in the electrolysis process are achieved.

Description

technical field [0001] The invention relates to the technical field of electrode preparation, in particular to an electrode preparation process with high flatness. Background technique [0002] With the continuous pollution of water resources on the earth and the continuous shortage of water resources, disinfection water treatment is becoming more and more important; chlorination disinfection is currently the most widely used water disinfection method, which plays an important role in preventing water-borne diseases . Adding chlorine or hypochlorite (such as NaClO, etc.) to water will generally generate hypochlorous acid (HClO) and hydrochloric acid (HCl). Sodium hypochlorite generator produces low-concentration sodium hypochlorite solution, which has good disinfection effect, accurate dosing, safe operation, convenient use, easy storage, non-toxic to the environment, and no secondary pollution, which is very advantageous. [0003] The electrolytic cell is the production s...

Problems solved by technology

However, the titanium substrate disclosed in this invention has the following defects: the titanium substrate is extremely easy to bend and deform during sandblasting and high-temperature baking, which will lead to difficulties in assembling the electrode group, uneven electrode spacing, and eventually lead to electrolysis of the sodium hypochlorite generator. During the process, the efficiency of electrolysis decreases, the heat generated by the electrolytic cell is large, and the energy consumption of operation increases.
