鋼木結構通風柜材質說明:

通風柜的主要功能:

通風柜的功能中最主要的是排氣功能,在化學實驗室中,實驗操作時產生各種有害氣體、臭氣、濕氣以及易燃、易爆、腐蝕性物質,為了保護使用者的安全,防止實驗中的污染物質向實驗室擴散,在污染源附近要使用通風柜,以往通風柜使用臺數較少,只在特別有害且危險的氣體及產生大量熱的實驗中使用。通風柜只擔負實驗臺的輔助功能。考慮到改善實驗環境,在實驗臺上進行的實驗逐漸轉移到通風柜內,這就要求在通風柜里要有最適于設備使用的功能。特別是大多新建的實驗室都要求有空調,因此在建筑的初步設計階段就要將通風柜的使用臺數納入空調系統的計劃。由于通風柜在生化實驗室中占有非常重要的位置,從改善實驗室環境、改善勞動衛生條件,提高工作效率等方面考慮,通風柜的使用臺數飛躍地增加。隨之而來的是通風管道,配管、配線、排風等都成為實驗室建設的重要課題。

使用通風柜的最大目的是排出實驗中產生的有害氣體,保護實驗人員的健康,也就是說要有高度的安全性和優越的操作性,這就要求通風柜應具有如下功能:

(5) 控制風速功能:為防止通風柜內有害氣體逸出,需要有一定的吸入速度。決定通風柜進風的吸入速度的要素有:實驗內容產生的熱量及與換氣次數的關系。其中主要的是實驗內容和有害物的性質。國家標準規定,通風柜的面風速為0.5 m/s±10% 。為了確保這樣的風速,排風機應有必要的靜壓,即空氣通過通風管道時的摩擦阻力。確定風速時還必須注意噪音問題,通過空氣在管道內流動時以7―10m為限,超過10m將產生噪音,通常實驗室的(室內背景噪聲級)噪聲限制值為70dBA,增加管道裁面積會降低風速(6) 耐熱及耐酸堿腐蝕功能。通風柜內有的要安置電爐,有的實驗產生大量酸堿等有毒有害氣體具有極強的腐蝕性。通風柜的臺面,襯板、側板及選用的水咀、氣咀等都應具有防腐功能。在半導體行業或腐蝕性實驗中使用硫酸、硝酸、氫氟酸等強酸的場合還要求通風柜的整體材料必須防酸堿,通常采用不銹鋼、PVC或PP材料制造。

主體框架采用60*40*2mm進口矩形鋼管經二氧化碳焊接制作成C形鋼支架、連接支撐橫梁采用60*40*2mm進口矩形鋼管,表面經除油、酸洗、磷化作防銹處理,再靜電粉沫噴涂EPOXY防護層做耐酸堿耐腐蝕表面處理,其噴涂EPOXY防護層附著力經落物撞擊試驗測試合格;通風柜柜體抽面與門板采用16mm厚的國產優質環保型中纖板,表面粘壓國產優質1.0mm厚珍珠面防火板,所有斷面經經國產優質2.0mm厚PVC封邊防水處理,四周做倒角圓滑處理,外表美觀、光滑;柜體柜身采用16mm厚國產優質環保型三聚氰胺板;所有斷面經經國產優質PVC封邊防水處理,柜身板件采用可拆裝式三合一連接,結構穩固,承重性好;鉸鏈采用國產優質全開式90-175度高質鍍鉻鋼鉸鏈,與柜體面水平角度<15度時,柜門即可自行關閉,彈性好,外形美觀,使用過程中無噪音,可自由開合五萬次以上;拉手采用不銹鋼拉手或PVC一字暗拉手。

臺面:采用進口陶瓷臺面、進口環氧樹脂臺面、千思板、實心理化板,耐酸堿、耐腐蝕;邊緣加厚至26mm,防止液體外溢。

可視窗:≥5mm厚防爆鋼化玻璃,滑動自如,可停留于軌道任何位置;主視窗玻璃可左右自由滑動,方便使用者操作。

插座:采用防塵、防濺帶有自動閉合功能防護蓋的安全插座。外型尺寸為60×60mm,10A/16A /220V的多功能插座,適合實驗室內各種儀器設備。

照明:采用圓形節能孔燈,隱藏于頂板上,不與通風柜內實驗氣體直接接觸,易更換,亮度完全滿足實驗要求。

控制面板:萬用插座、日光燈、風機、風閥開停控制。

杯槽:配進口PP杯槽,耐酸堿、耐腐蝕和有機物。

水龍頭:采用進口優質單口水龍頭;材質為純銅質;表面處理采用進口環氧樹脂粉未噴涂,耐酸堿,耐腐蝕;出水嘴采用銅質和PP兩種材質,可拆卸,加接安裝起泡器,鵝頸、折角出水管可360°旋轉,有成型螺紋,可方便連接循環等特殊用水水管;閥芯采用精密陶瓷閥芯,90°旋轉,開關使用壽命達50萬次以上,靜態最大耐壓35巴;把手采用PP材質,符合人體工學設計,使用手感舒適、方便。
