The invention provides a polar plate curing process, and relates to the field of battery production methods. The method comprises the following steps: step 1, arranging a curing chamber, and mounting a polar plate to be cured in the curing chamber; step 2, reducing the pressure in the curing chamber to be in a negative pressure or vacuum state, and introducing pure oxygen into the curing chamber in the negative pressure or vacuum state; step 3, heating the curing chamber filled with the pure oxygen; step 4, performing humiture control on a curing environment in the curing chamber according to polar plate curing process requirements; step 5, drying the polar plate to complete the process. According to the process, an oxygen-enriched environment can be quickly formed in the curing chamber, and meanwhile, the temperature, the humidity and the pressure in the curing chamber are monitored, so that real-time adjustment can be realized to ensure the polar plate curing quality.

Description

A kind of polar plate solidification technique
Technical field
The present invention relates to cell production method field, particularly relate to a kind of polar plate solidification technique.
Background technology
Need in lead-acid storage battery production to be cured pole plate, in existing curing process pole plate in the curing process oxygen content be around difficult to ensure, reaction is difficult to fully, under curing room humiture, place 48h ~ 72h simultaneously, to prevent pole plate dehydration from too much causing pole plate to ftracture in the process, affect polar plate solidification, the surface corrosion (grid starts surface corrosion after 24h at 30 DEG C) of electrode plate grid will be completed simultaneously.This solidifies its temperature is room temperature, substantially do not controlled, impact by outdoor environment temperature is larger, season will bring greater impact to indoor solidification, and the drying of pole plate is by sun and air-dry substantially, the water content of its green plate is more difficult to control, and the content of other components all can not reach technical requirement, makes battery capacity, life-span all rare to keep.
Summary of the invention
The invention provides a kind of polar plate solidification technique for the deficiencies in the prior art part, the method can make to form oxygen-enriched environment fast in curing room, carries out monitoring simultaneously and adjust with the quality ensureing polar plate solidification in real time the temperature humidity pressure in curing room.
Technical scheme of the present invention is to provide a kind of polar plate solidification technique, comprises the following steps:
Step one, arranges curing room, is placed in by pole plate to be solidified in described curing room;
Step 2, is reduced to negative pressure or vacuum state by described curing room internal gas pressure;
Step 2, the described curing room to negative pressure or vacuum state is filled with pure oxygen;
Step 3, heats to the described curing room being full of pure oxygen;
Step 4, carries out Temperature and Humidity Control to the curing environment of described curing room according to polar plate solidification technological requirement;
Step 5, dry pole plate completes technique.
This method by passing into pure oxygen in vacuum or subnormal ambient, makes curing room can reach oxygen enrichment at short notice and uniform curing environment, and can also ensure also to be incorporated in moisture a large amount of oxygen becomes heavy-oxygen-enriched water and ensure that the abundant of reaction simultaneously.
As preferably of the present invention, in described step one, the mode of pole plate to be solidified by superposition is settled with in described curing room.
As preferably of the present invention, in described step 2, described curing room internal gas pressure is reduced to vacuum state.
As preferably of the present invention, the curing room in described step one keeps humidity more than 95%.
As preferably of the present invention, the mode of heating to the described curing room being full of pure oxygen in described step 3 for passing into steam, and keeps described curing room to be 40 DEG C ~ 50 DEG C in execution step 3 to temperature during step 4.
As preferably of the present invention, pressure sensor is provided with in described curing room, utilize described pressure sensor to monitor the pressure in described curing room, report to the police when the pressure change in described curing room is more than 5% ~ 20% to during step 5 in execution step 3.Ensure that the fail safe of this invention after enforcement.
As preferably of the present invention, in described curing room, be provided with Temperature Humidity Sensor.
As preferably of the present invention, the built-in chamber of described curing room is circular.
As preferably of the present invention, described step 5 is by dehumidifier and the dry pole plate of mode coordinated of heating.
As preferably of the present invention, the temperature in curing room described in described step 5 remains on more than 75 DEG C, and humidity remains on 2% ~ 20%.
The present invention has following beneficial effect:
The present invention has efficiently, be cured substrate fully, and solidification good quality, the advantage of solidification process safety.
Embodiment
The present embodiment comprises the following steps:
Step one, arrange curing room, be placed in curing room by pole plate to be solidified, the method for arrangement is that the mode superposed up and down by pole plate is settled, also can be settled by placing frame, but being preferably stacked system significantly reduces curing room volume needs;
Step 2, is reduced to negative pressure or vacuum state by curing room internal gas pressure, is preferably vacuum state;
Step 2, the curing room to negative pressure or vacuum state is filled with pure oxygen;
Step 3, heats to the curing room being full of pure oxygen;
Step 4, carries out Temperature and Humidity Control to the curing environment of curing room according to polar plate solidification technological requirement;
Step 5, completes technique by dehumidifier with the dry pole plate of mode coordinated of heating.
Curing room in the present embodiment in step one keeps humidity more than 95%.Temperature in step 5 in curing room remains on more than 75 DEG C, and humidity remains on 2% ~ 20%, is preferably 20%.
This method by passing into pure oxygen in vacuum or subnormal ambient, makes curing room can reach oxygen enrichment at short notice and uniform curing environment, and can also ensure also to be incorporated in moisture a large amount of oxygen becomes heavy-oxygen-enriched water and ensure that the abundant of reaction simultaneously.Simultaneously owing to being vacuum state, so the air between pole plate in gap also can be drawn out of, at this moment pass into also can these spaces of Fast Filling for pure oxygen, so vacuum can also solve oxygen content deficiency in pole plate gap, the air circulation problem that cistron is not insufficient, so just significantly can lower the gap between pole plate, make the smaller volume of curing room, curing room smaller volume accelerates again even speed and the even level of indoor oxygen content further.
The mode of heating to the curing room being full of pure oxygen in step 3 in the present embodiment for passing into steam, and keeps curing room to be 40 DEG C ~ 50 DEG C in execution step 3 to temperature during step 4, specifically according to weather pole plate itself state and determine.
Be provided with pressure sensor in curing room in the present embodiment, utilize pressure sensor to monitor the pressure in curing room, report to the police when the pressure change in curing room is more than 5% ~ 20% to during step 5 in execution step 3, specifically determine according to process requirements.Temperature Humidity Sensor is provided with in curing room.
In the present embodiment, the built-in chamber of curing room is circular, and circle can pressure-bearing, but also can use square or other there is the shape of bearing capacity.
