蓄電池管式極板制造方法 |
| 擠膏是蓄電池管式極板制造法之二，將鉛膏灌進(jìn)管內(nèi)。這里用的鉛膏比較稀，只用稀硫酸與木炭粉（或硫酸鎂）與水一起和制稀鉛膏，鉛膏的視密度為3.4-3.8g/cm3擠膏后封底，板表洗滌后直接進(jìn)行干燥，進(jìn)人化成。板柵上剛涂填新鮮鉛膏的極板仍然很軟很粘，必須進(jìn)行極板表面快速干燥，然后板間互不粘連，疊片進(jìn)人一個緩慢干燥（固結(jié)）過程。這樣得到的極板力學(xué)性能好、強(qiáng)度高，這一強(qiáng)化過程叫作“固化”。這在20 世紀(jì)50 年代初作為一個特殊的工藝在世界鉛酸蓄電池行業(yè)推廣使用。這一過程中要使涂填的鉛青能與板柵表面緊密結(jié)合，又要使鉛膏粒子之間結(jié)合牢固。要使整個涂填的鉛膏進(jìn)行全面結(jié)構(gòu)轉(zhuǎn)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. |
