Charging, will cause the battery oxygen evolution positive, increasing the internal pressure and more active substances fall off, if long-term charging positive for oxygen evolution, then corrosion, at the same time the electrolyte water loss intensifies, batteries have dried up risk; Long-term owe charging, easy to cause the battery charge electricity shortage, the serious influence of battery capacity, also can cause damage to the battery; A discharge, can make the plate surface to generate the recovery of the large particles PbSO4 crystallization, causing the plate sulfated, greatly reduce the plate of active material hole rate.

The overflow of gypsum slurry cyclone were observed and tested, resulted show that: the main properties of the overflow slurry for: small density, light weight, its color and the main components and the absorber slurry layer better liquidity matter was basically the same; cyclone underflow slurry density high, high solid content, its color and the main composition and absorption tower bottom mobility was poor material was basically the same; absorption tower slurry, gypsum, gypsum slurry cyclone overflow the color shown in Figure 1 to 3.
