工業(yè)氣體在國家標(biāo)準(zhǔn)《常用危險(xiǎn)化學(xué)品的分類及標(biāo)志》(GB13690-1992)中，通常被劃為第2類壓縮氣體和液化氣體。這類化學(xué)品系指壓縮、液化或加壓溶解的氣體。氣體經(jīng)加壓或降低溫度，可以使氣體分子間的距離很大的縮小而被壓入鋼瓶中，這種氣體稱為壓縮氣體(亦稱為長久氣體，如氧氣、氮?dú)?、氬氣、氫氣?。對壓縮氣體繼續(xù)加壓，適當(dāng)降溫，壓縮氣體就會(huì)變成液體的，稱為液化氣體(如液氯、液氨、液體二氧化碳等)。此外，還有一種性質(zhì)極為不穩(wěn)定的氣體，加壓后需溶于溶劑中儲(chǔ)存在鋼瓶內(nèi)，這種氣體稱為溶解氣體(如溶解乙炔等)。</p><p> 眾所周知,裝入高壓容器(鋼瓶)中的標(biāo)準(zhǔn)氣體的一個(gè)重要條件是在保存和使用過程中其量值不應(yīng)發(fā)生變化。實(shí)際上,標(biāo)準(zhǔn)氣體中成分氣體或不純物與容器內(nèi)壁接觸時(shí)往往引起吸附、解吸、化學(xué)反應(yīng)等現(xiàn)象,而使其量值隨時(shí)間發(fā)生變化,在含量越低,組成成分越復(fù)雜時(shí),這種變化就越大。標(biāo)準(zhǔn)氣體穩(wěn)定性研究如下：氣體要求配制10%的CH4/Ar四瓶,進(jìn)行為期一年的穩(wěn)定性考察,見表1,實(shí)驗(yàn)結(jié)果表明,由于鋁合金鋼瓶內(nèi)壁比較光滑,因此在盛裝一般長久氣體時(shí)性質(zhì)穩(wěn)定,變化不大,鋼瓶不用特殊處理,即可滿足此類標(biāo)準(zhǔn)氣體穩(wěn)定性的要求。在配制COS、H2S、SO2等氣體時(shí),必須對鋼瓶進(jìn)行KG或CM處理,即為了防止容器內(nèi)壁因吸附或解吸等帶來的影響。先對容器內(nèi)壁進(jìn)行鏡面研磨,涂上防氧化漆,然后把高濃度氣體充入容器內(nèi)并放置10d左右,從而提高標(biāo)準(zhǔn)氣體的穩(wěn)定性。用未經(jīng)KG或CM處理的鋼瓶配制。用經(jīng)KG處理的鋼瓶配制。以上實(shí)驗(yàn)結(jié)果表明,配制易吸附標(biāo)準(zhǔn)氣體時(shí),鋼瓶必須經(jīng)KG或CM處理,才能保證其穩(wěn)定性可靠,否則,組分氣的含量變化很大,不宜作為標(biāo)準(zhǔn)氣體來使用。氣體供應(yīng)商——常州大成工業(yè)氣體有限公司。</p><div
