style="text-indent:25px">通風(fēng)柜的功能中主要的是排氣功能，在化學(xué)實(shí)驗(yàn)室中，實(shí)驗(yàn)操作時(shí)產(chǎn)生各種有害氣體、臭氣、濕氣以及易燃、易爆、腐蝕性物質(zhì)，為了保護(hù)使用者的安全，防止實(shí)驗(yàn)中的污染物質(zhì)向?qū)嶒?yàn)室擴(kuò)散，在污染源附近要使用通風(fēng)柜，以往通風(fēng)柜使用臺數(shù)較少，只在特別有害且危險(xiǎn)的氣體及產(chǎn)生大量熱的實(shí)驗(yàn)中使用。通風(fēng)柜只擔(dān)負(fù)實(shí)驗(yàn)臺的輔助功能?？紤]到改善實(shí)驗(yàn)環(huán)境，在實(shí)驗(yàn)臺上進(jìn)行的實(shí)驗(yàn)逐漸轉(zhuǎn)移到通風(fēng)柜內(nèi)，這就要求在通風(fēng)柜里要有適于設(shè)備使用的功能。特別是大多新建的實(shí)驗(yàn)室都要求有空調(diào)，因此在建筑的初步設(shè)計(jì)階段就要將通風(fēng)柜的使用臺數(shù)納入空調(diào)系統(tǒng)的計(jì)劃。由于通風(fēng)柜在生化實(shí)驗(yàn)室中占有非常重要的位置，從改善實(shí)驗(yàn)室環(huán)境、改善勞動衛(wèi)生條件，提高工作效率等方面考慮，通風(fēng)柜的使用臺數(shù)飛躍地增加。隨之而來的是通風(fēng)管道，配管、配線、排風(fēng)等都成為實(shí)驗(yàn)室建設(shè)的重要課題。玻璃鋼通風(fēng)柜的使用數(shù)量突飛猛進(jìn)。</p><div
