在微電子工業(yè)，精密儀器，LED，液晶等等那些從事精密的生產(chǎn)和科學實驗活動，出于生產(chǎn)的需要得達到一定無塵生產(chǎn)環(huán)境，而專門建設無塵廠房、無塵車間或者無塵室的需要而產(chǎn)生的一門技術，它就是潔凈技術。<span style="font-size:12px;">它是為了適應實驗研究與產(chǎn)品加工的精密化、微型化、高純度、高質(zhì)量和高可靠性等方面要求而誕生的一門新興技術。</span><span style="font-size:12px;">潔凈室（cleanroom）這個名詞和概念源于18世紀六十年代的歐洲醫(yī)學，當時的理解*于經(jīng)噴灑消毒后可以控制創(chuàng)部率的處置室、手術室這類滅菌處理的工作環(huán)境。</span><span style="font-size:12px;">現(xiàn)代潔凈室雖然延用了這個名詞，但在定義和內(nèi)涵上都與原有的概念有根本的不同，現(xiàn)代潔凈室形成一項專門技術，其歷史不過只有半個世紀。</span> 青海潔凈車間施工江蘇準潔凈車間哪家好，就選立鵬科技。</p><div style="width:100%;text-align: center;"><img

壓差原則就是防止較不潔凈區(qū)的氣流向潔凈區(qū)倒灌（例如通過門縫），即在潔凈室內(nèi)保持恒定的高壓（５～２０Ｐａ）。其氣流組織原則是低速氣流由潔凈室向著鄰近區(qū)域并保持相對高的壓差。受控參數(shù)就是壓差。排風原則就是形成低渦流或近似于單向氣流，風速大于０。２米／秒，由較潔凈區(qū)吹向較不潔凈區(qū)，以防止氣流倒灌。在應用此種方式時，應考慮到障礙物，熱源和污染物，排風格柵位置等的影響。此項原則的特點就是低壓差，相對高的氣流風速。運用此項原則的實例就是位于較低潔凈度級別房間內(nèi)的層流潔凈區(qū)（單向氣流區(qū)）。區(qū)域的物理分隔原則就是建立隔離裝置，對由較低潔凈度的房間產(chǎn)生的污染形成不可逾越的屏障，不致進入較高潔凈度的潔凈室。如果是具有有害物的生產(chǎn)過程（個別品種的致病微生物，強烈反應的化學制劑），則應保證該處的氣壓相對于環(huán)境是負壓。應予指出，建立負壓的要求是與潔凈室的工作原理相矛盾的，潔凈室是基于正壓差的。為了解決此項矛盾，便采用了另加的氣閘室，在潔凈室周圍建立第二層密閉外殼（包括吊頂）使氣閘室相對于鄰近房間和有害作業(yè)具有高的正壓。為此，就可以采用隔離工藝，例如，在接觸有毒制劑時采用具有負壓得隔離裝置。 </p><p> 單向流潔凈室，<span style="font-size:12px;">單向流潔凈室也叫層流潔凈室也分為垂直流動潔凈室和水平流動潔凈室，其氣流是從室內(nèi)送風一側(cè)平行、直線、平穩(wěn)地流向相對應的回風側(cè)，它是將室內(nèi)污染源的污染物在未向室內(nèi)擴散之前就被潔凈空氣壓出房間，送入的清潔空氣對污染源起隔離作用。</span><span style="font-size:12px;">特點：流線單向平行，是指時均流線彼此平行，方向單一，并且干凈氣流不是一股或幾股，而是充滿全室斷面，所以這種潔凈室不是靠潔凈氣流對室內(nèi)臟空氣的摻混稀釋作用，而是靠潔凈氣流推出作用將室內(nèi)臟空氣沿整個斷面排至室外，達到凈化室內(nèi)空氣的目的。</span> 江蘇潔凈車間行業(yè)哪家好，就選立鵬科技。</p><div

近年來,在大規(guī)模集成電路生產(chǎn)用潔凈廠房中常常采用隧道式送風、集中送風和風機過濾單元（FFU）送風方式,各類機房的布置基本采用“混合設置”的方式,即新風處理機集中設置,循環(huán)空氣機組分散設置。為了保證潔凈室圍護結構的氣密性(抗?jié)B性)，避免裂縫，除了圍護結構的材料選擇和結構處理外，還應使主體結構具有良好的抗震性能、溫度變形控制性能和基礎不均勻沉降性能。在地震多發(fā)區(qū)，主體結構應具有良好的整體性和足夠的剛度，潔凈室主體結構應盡量受力均勻，車間變形縫應盡量避免穿過潔凈區(qū)。青海潔凈車間施工</p></p><br
