É um material inflamável, mas pode causar inflamação继续从你断开的地方 nâo. 是一种易燃物质,但可能引起自燃。如果氧气瓶阀上粘有油脂,在氧气瓶充装和使用过程中,氧气高速流过瓶阀时,就能引起瓶阀着火,甚至使氧气瓶爆炸。所以氧气瓶是严禁沾上油脂的。瓶阀上的油脂都是由于忽视安全,严重违反安全操作规程造成的。在充装、使用过程中由操作者有油污的手、手套、工作服和工具沾上去的;也可能在检验、更换瓶阀时未作严格的脱脂处理。瓶内的油脂可能是气瓶曾装过含有油脂的气体。在作气瓶的定期检验时,为了判别气瓶内壁是否有油脂,通常采用下列方法: 1) 将涮洗气瓶的水倒在杯中,静置一段时间后,在水面上放一张香烟纸,停留片刻后取出烘干。若在纸上留有油污痕迹,则表明瓶内含有油脂; 2) 将涮洗气瓶的水倒在杯中,用小勺取少许纯樟脑粉洒于杯内水面。若樟脑粉在水面发生强烈旋转,则表明瓶内含有油脂。这是因为樟脑粉不溶于水,但能溶于油脂。在溶解时产生溶解热而使水局部汽化,造成樟脑粉产生旋转。 需进行除油处理时,应用干净的去油剂去油。", "明白了,感谢楼主分享。
