style="text-indent:25px">在日常使用實(shí)驗(yàn)室設(shè)備通風(fēng)柜的時(shí)候，必須要做好安全事項(xiàng)的準(zhǔn)備。在使用之前，我們必須要做好電源方面的檢測(cè)，而且也要確定好排水和氣體等開(kāi)關(guān)、管路是否可以正常使用。同時(shí)，我們也要打開(kāi)照明設(shè)備，這樣才能夠確定好柜子內(nèi)部是否可以正常運(yùn)作等。建議在使用之前，先開(kāi)機(jī)三分鐘左右的時(shí)間，確定一下內(nèi)部是否可以正常運(yùn)行。一定要按照以上的順序來(lái)進(jìn)行整體上的檢查，如果出現(xiàn)了問(wèn)題必須要暫停使用。在使用實(shí)驗(yàn)室設(shè)備通風(fēng)柜之后，我們也要做好相應(yīng)的檢測(cè)工作，在關(guān)機(jī)之前必須要再讓抽風(fēng)機(jī)運(yùn)轉(zhuǎn)幾分鐘，因?yàn)槠鋬?nèi)部還可能存在一定殘留的氣體，所以必須要將所有的氣體排出才能夠保證后期使用沒(méi)有問(wèn)題。使用之后我們也要將通風(fēng)柜進(jìn)行內(nèi)外部的清潔，關(guān)閉各項(xiàng)之后也要做好檢查。是能夠落實(shí)到人頭，讓所有的工作人員按要求操作，這樣實(shí)驗(yàn)才能夠安心完成。在半導(dǎo)體行業(yè)或腐蝕性實(shí)驗(yàn)中使用硫酸、硝酸、氫氟酸等強(qiáng)酸的場(chǎng)合還要求通風(fēng)柜的整體材料必須防酸堿。寧波實(shí)驗(yàn)室整體通風(fēng)公司</p><p

1、玻璃視窗采用鋼化玻璃，即使玻璃意外撞壞或，不會(huì)出現(xiàn)傷人意外。 2、通風(fēng)柜上部設(shè)置通風(fēng)孔，即使玻璃視窗關(guān)閉也能進(jìn)入空氣，避免產(chǎn)生更大負(fù)壓。 3、通風(fēng)柜殼體選用金屬材料，防火不燃。內(nèi)腔選用抗倍特板，不銹鋼板等阻燃或不燃材料，臺(tái)面選用實(shí)芯理化板或不銹鋼板防酸堿、耐熱、阻燃。 4、玻璃視窗有效高度800mm，內(nèi)腔1200mm，臺(tái)面高度800mm，符合人體工程學(xué)，便于操作，使用空間大，提高安全性。 5、水咀、氣咀在柜外設(shè)遠(yuǎn)距離操作手把，比直接用手操作更方便安全。寧波實(shí)驗(yàn)室整體通風(fēng)公司</p></p><br /><p>文章來(lái)源地址: http://www.cdcfah.com/cp/3105545.html</p></div></div></div></div></div><div id="zri43m2"
