蓄电池管式极板制造方法

挤膏是蓄电池管式极板制造法之二，将铅膏灌进管内。这里用的铅膏比较稀，只用稀硫酸与木炭粉（或硫酸镁）与水一起和制稀铅膏，铅膏的视密度为3.4-3.8g/cm3挤膏后封底，板表洗涤后直接进行干燥，进人化成。板栅上刚涂填新鲜铅膏的极板仍然很软很粘，必须进行极板表面快速干燥，然后板间互不粘连，叠片进人一个缓慢干燥（固结）过程。这样得到的极板力学性能好、强度高，这一强化过程叫作“固化”。这在20 世纪50 年代初作为一个特殊的工艺在世界铅酸蓄电池行业推广使用。这一过程中要使涂填的铅青能与板栅表面紧密结合，又要使铅膏粒子之间结合牢固。要使整个涂填的铅膏进行全面结构转型。Paste squeezing is the battery tube plate manufacturing method of two, will paste into tube. The paste is more rare, with dilute sulfuric acid and charcoal powder ( or magnesium sulfate ) together with water and preparation of thin paste, paste as the density of 3.4-3.8g/cm3 paste squeezing after sealing, sheet wash directly after drying, entering into. Plate gate just filling fresh paste plate is still soft and sticky, must undertake the plate surface, fast drying, then the board without mutual adhesion, laminated into a slowly drying process ( consolidation ). The plate has good mechanical performance, high strength, this intensive process called " curing ". In the early nineteen fifties as a special technology in the world of lead-acid battery industry to promote the use of. The process to make filling lead green with grid surface tightly, and make the paste bonding between the particles is firm. To make the filling paste overall structural transformation.
