style="text-indent:25px">真空的材料的放氣是真空閥門總漏量中的一個(gè)重要組成部分。氣體的來源主要有：吸附于真空閥零件內(nèi)表面的氣體；從金屬內(nèi)部擴(kuò)散出來的氣體以及金屬表面因發(fā)生某種化學(xué)反應(yīng)而釋放出來的氣體。1、不銹鋼的放氣量很小。只及銅的1/10左右，與鋁相比，則*為它的1/100左右；2、橡膠與樹脂的放氣量比金屬材料都要高出100倍左右，比較高的如硅橡膠則要高出1000倍以上。放氣現(xiàn)象與溫度有關(guān)，溫度越高，放氣速率越大。因此用加熱方法除氣是一種十分有效的手段，材料經(jīng)過烘烤后的放氣量要極大低于未烘烤時(shí)的放氣量。濟(jì)南GU型-手動(dòng)高真空球閥</p><p
