一、引言灯泡在排气烘烤过程中,玻壁所吸着的大部分气体已被清除。但在高温发光的使用过程中,它仍不断地释放出水、二氧化碳和一氧化碳等气体,泡壳温度越高,释气量越多。钨丝和金属导丝也会放出H_2、CO_2、CO。钨丝中残留的WO_3,当灯丝高温发光时,发生分解,生成分子氧。拉制钨丝所用的石墨残留在灯丝上,构成碳的主要来源。填充 First, the introduction of light bulbs in the exhaust baking process, most of the glass wall suction gas has been cleared. However, in the process of using high-temperature light, it continues to release water, carbon dioxide and carbon monoxide and other gases, the higher the bulb temperature, the more the amount of outgassing. Tungsten wire and metal guide wire will release H_2, CO_2, CO. WO_3 remains in the tungsten filament. When the filament emits light at high temperature, it decomposes to generate molecular oxygen. Drawn tungsten filament used in the filament remaining on the filament, the main source of carbon. filling
