Analysis on the changes in the drying process of the battery of the batteryThe process of drying the battery lead paste drying occurs in contrast to the cream, the step of the drying process is: a. The first water evaporates from the capillary hole space (first aperture, which is a small hole); b. Secondary water evaporates from the liquid film (very thin liquid film) between the particles, starting as a result of the reduction in the thickness of these films, resulting in a reduction in the cross section of the hole, eventually leading to the contraction of the battery lead paste, if these are in the lead paste The volume reduction is suddenly (huge) change, which will cause the crack of the lead paste or even the lead paste of some parts to fall off; c. Then, the third step is evaporated from the wedge-shaped return, whether it is a lead paste size or a porosity, it remains unchanged in this step. Due to the evaporation of water, the above process is formed to form the radius and hole volume of the hole, and some differences are still different from the inspection. It can be seen that the moisture content is reduced to form a hole in size, first is dry, then the discard in the small hole. Its water is 11.3% in the lead paste; the formed holes are greater than the aperture of 0.34 um, and those holes corresponding to the water content of 3.9%.
