style="text-indent:25px">通風柜的選擇需要符合一定的標準，那么在選用通風柜時需要參照什么考核因素呢?實驗室中各種實驗室家具都符合相關(guān)的規(guī)定，通風柜的材料要具備理化性能好、耐腐蝕、易清洗的特點。其次，是通風柜的臺面，襯板、側(cè)板及選用的水咀、氣咀等都應具有防腐功能。由于實驗室氣體排放中存在著很多有毒和酸堿腐蝕性極強的氣體，所以在排入大氣前要對氣體進行過濾處理，通常情況下：酸性氣體選用立式酸霧塔;有毒和有機氣體選用光學催化凈化箱。兩種設(shè)備分別安裝在排風系統(tǒng)末端，立式酸霧塔安裝在風機的正壓段，光學催化凈化箱安裝在風機負壓段。動物房的氣體經(jīng)過初效和中效過濾后，直接排入大氣，但在排風口處做高壓噴射流處理，噴射高度在3米以上。實驗室通風系統(tǒng)設(shè)計方法，因此，實驗室通風系統(tǒng)對設(shè)備(特別是通風柜)是有一定標準和要求的。</p><p style="text-indent:25px">正確使用通風柜注意要點：1、操作人員在通風柜前工作時隨時與調(diào)節(jié)門保持150mm以上距離。2、從柜內(nèi)取出物品時動作宜小。3、不工作時，應確保玻璃視窗處于關(guān)閉狀態(tài)。4、調(diào)整導流板需要在制造商或有資質(zhì)的相關(guān)人員指導下進行。5、將柜內(nèi)污染物及設(shè)備等墊高，同通風柜臺面板隔空，以使氣流能從其下方通過。6、如需在通風柜內(nèi)儲放必要物品或設(shè)備時，應盡量將其置于左右側(cè)邊上，并且遠離污染產(chǎn)生源。不可儲存會伸出柜外或妨礙調(diào)玻璃視窗開合或者會阻擋導流板下方開口處的物品或設(shè)備。7、盡量減少在通風柜內(nèi)以及調(diào)節(jié)門前進行大幅度動作。8、當在通風柜前工作時，應盡量減低實驗室內(nèi)人員移動，若在通風柜前人員移動頻繁將會造成大量的橫越氣流。9、在通風柜實驗進行中的任何時刻，人員頭部以及上半身絕不可伸進通風柜內(nèi)。低速通風柜也被稱為高性能通風柜或高效通風柜。</p><div

style="text-indent:25px">通風柜材料主要是由多種全鋼、鋼木、全木等等特殊材料制成。而直接和試驗樣品相接觸的地方。通常是由環(huán)氧樹脂板、實心理化板、陶瓷板、不銹鋼板等多種材料制成。這比舊式的單純由木材制成的通風的柜子有效減少了制造成本、占用體積及其重量、有效增加了承重能力、性價比獲得了明顯的提高。通風柜一般是靠墻安裝。大多數(shù)的通風的柜子在排氣量過小的情況下會自動發(fā)出警報。使用時實驗者只需要站或者坐于柜前，在柜子下方的通風柜上進行實驗操作即可。實驗室這類柜子的種類如果按照功能特點分的話有這樣幾種：項抽式柜子、狹縫式柜子、旁通式柜子、補風式柜子、還有自然通風式的柜子。試驗臺使用玻璃鋼通風柜的優(yōu)勢是什么？寧波質(zhì)量好的多功能通風柜</p><p style="text-indent:25px">雖然每個實驗室的通風柜面風速都沒有精確的數(shù)字，但標準的狀態(tài)范圍通常為60到100 fpm。寧波質(zhì)量好的多功能通風柜</p><p style="text-indent:25px">實驗室通風柜的位置選擇:常規(guī)通風柜高度2350mm，那么安裝通風柜的實驗室高低較低不能低于2900mm的凈高，通風柜管道一般是250mm直徑或者是200mm直徑，當然粗一點的管道排風效果還是要好一些，噪音相對來說要低。安裝通風柜開排風孔時常規(guī)尺寸是離地面高度2700mm中心點為宜，前后距離為450mm左右。許多人都會習慣性地把通風柜安置在墻角，離實驗的地方遠遠的，省的占著其它實驗家具的地方。其實，這種想法是錯誤的，不管柜占了多大的地方，都應該將它放在離試驗臺較近的地方,主要的是通風柜盡量安裝在離窗戶近點的地方，這樣管道就容易排到室外去，管道越短排風效果越好。通常情況下，應該把通風柜安置在靠近試驗臺的位置，因為每一次有毒氣體或粉塵的產(chǎn)生都是從試驗臺上傳出來的，這里是先受到污染也是污染嚴重的“重災區(qū)”。我們要隨時有防患于未然的安全意識，隨時做好各項預防措施。大型的通風設(shè)備雖然占地較大，但通風效果也很好。寧波質(zhì)量好的多功能通風柜</p></p><br
