Embodiment Construction

[0018] The following takes a plate with a thickness of 1.5mm as an example to introduce the curing and drying method:

[0019] Put a plurality of coated raw plates (negative plates for conventional lead-acid battery plates) together into the curing chamber, perform curing and drying according to the following method, and randomly select 5 of the plates and number them 1- 5 and test.

[0020] In the rapid curing stage, the temperature is 300°C, the time is 35s, and the humidity is 10%. In the normal temperature curing stage, the temperature is 80°C, the time is 5h, the humidity is 95%, and the drying stage is at 80°C, the time is 16h, and the humidity is 0%. In the room temperature curing stage and drying stage, the plates are placed seamlessly.

[0021] The other part of the above-mentioned green electrode plates of the same batch is subjected to ordinary curing and drying, that is, curing at room temperature first, and then drying. In the normal temperature curing stage, th...

Abstract

The invention discloses a curing and drying method applied to a lead-acid storage battery plate. The method comprises the step of: curing a pasted green plate in a quick surface drying stage, a normal temperature curing stage and a plate drying stage, wherein the curing conditions of the quick surface drying stage comprise temperature of 200 to 320 DEG C, time of 30 to 40 seconds and humidity of less than 20 percent; the curing conditions of the normal temperature curing stage comprise temperature of 50 to 85 DEG C, time of 5 to 10 hours and humidity of 85 to 99 percent; and the curing conditions of the plate drying stage comprise temperature of 70 to 85 percent, time of 15 to 17 hours and humidity of less than 20 percent. By the method, curing and drying time can be effectively saved, and generally, 20 to 21 hours are required for curing; a plurality of green plates can be seamlessly arranged directly adjacent to each other, so that a curing space is greatly enlarged, and curing efficiency is greatly improved; and the free lead content and water content of the plate are superior to those in the conventional method.

Description

technical field [0001] The invention belongs to the field of lead-acid storage battery production, in particular to a curing and drying method for lead-acid storage battery plates Background technique [0002] The curing and drying of the raw plate is a key process in the manufacturing process of the lead-acid battery plate. It directly affects the difficulty of formation, the mechanical strength and electrical properties of the plate after formation, and is related to the capacity and life of the lead-acid battery. length. Therefore, the curing process of the coated green plate should not be taken lightly. [0003] The plate curing and drying process is to make the plate coated with wet paste evaporate the water in the plate under high humidity and a certain temperature, and make some changes in the wet paste, and finally the wet plate becomes dry with a certain strength. The green plate is used for subsequent processing. [0004] The chemical changes in the curing proce...
