Problems solved by technology

The sintering process in the prior art is to directly put the electrode plate into the sintering furnace for sintering, and then push it out of the sintering furnace to contact with room temperature for direct cooling, and sintering under the condition of sudden cooling and sudden heating. On the one hand, the electrode plate substrate The bond with the coating is not strong, on the other hand the applied coating is prone to cracking

Embodiment 1

[0028] Embodiment 1: The anti-cracking electrode plate coating sintering process for sewage treatment includes the following steps: the electrode plate coated with the coating enters the drying preheating section, the temperature of the drying preheating section is 150-200 ° C, and the drying The time for intervening in the hot section is 10-15 minutes; the electrode plate after drying and preheating will directly enter the high-temperature sintering section without contact with the outside. The temperature of the high-temperature sintering section is 400-550°C. 10-15min; the electrode plate after high-temperature sintering is directly put into the cooling and holding furnace to cool to 200-300°C without contacting the outside; after the electrode plate is cooled to 200-300°C, move the electrode plate to the external area for cooling to room temperature; repeat the above steps for more than two times with the electrode plate cooled to room temperature, and the time for the high...

Abstract

The invention provides an anti-cracking electrode plate coating sintering process for dirt water treatment. The sintering process comprises the following steps that an electrode plate coated with a coating is fed into a drying preheating section, wherein the temperature of the drying preheating section is 150-200 DEG C, and the time for drying and preheating in the drying preheating section is 10-15 minutes; the dried and preheated electrode plate directly enters a high-temperature sintering section under the condition that the electrode plate is not in contact with the outside, wherein the temperature of the high-temperature sintering section is 400-550 DEG C, and the time for drying and preheating in the high-temperature sintering section is 10-15 minutes; the electrode plate subjected to high-temperature sintering directly enters a cooling and heat-preserving furnace to be cooled to 200-300 DEG C under the condition that the electrode plate is not in contact with the outside; and after the electrode plate is cooled to 200-300 DEG C, the electrode plate is moved to an outer region to be cooled to the room temperature. An electrode plate coating in the process is higher in adhesion property and not prone to crack.

Description

technical field [0001] The invention belongs to the field of electrode plate sintering, and in particular relates to a coating sintering process of an anti-cracking electrode plate for sewage treatment. Background technique [0002] The electrode plate adopts the co-firing process of multiple coating and sintering to form the ohmic contact of the electrode. The sintering process in the prior art is to directly put the electrode plate into the sintering furnace for sintering, and then push it out of the sintering furnace to contact with room temperature for direct cooling, and sintering under the condition of sudden cooling and sudden heating. On the one hand, the electrode plate substrate The bond with the coating is not strong, on the other hand the coated coating is prone to cracking. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is a sintering process for anti-cracking electrode plate coating for sewage treatment. [0004] T...
