And the final plate quality of different areas also differs.
2. The conversion of free lead requires oxygen and moisture because of atmospheric curing, and oxygen needs a certain time to enter the gaps between the lead paste molecules, which is another reason for prolonging the total curing time.
3. When drying, the inside of the polar plate needs to be dried completely, the water inside needs to permeate outwards gradually, and the polar plate is evaporated by depending on the temperature, so that higher temperature and larger air volume are needed. For the arrangement mode without gaps between the polar plates, longer drying time is needed, and the production and operation cost is increased due to high temperature, strong wind and long time.
All the curing and drying are carried out under normal pressure, the curing and drying can be completed only by prolonging the time, and the air speed flowing through the polar plates placed in different areas is different, so that the physical and chemical indexes of the final polar plates are different.
