style="text-indent:25px">電子無塵車間：所謂半導(dǎo)體電子潔凈車間，指的是潔凈度在10萬級標(biāo)準(zhǔn)以上的車間，主要是按照按照每一立方米空氣中含有的0.5微米塵粒數(shù)計算。在絕大多數(shù)情況下，無塵車間運(yùn)行中風(fēng)速越低，過濾器的使用效果越好。小粒徑粉塵的擴(kuò)散作用(布朗運(yùn)動)明顯，風(fēng)速低了，氣流在過濾材料中滯留的時間就長一些，粉塵就有更多的機(jī)會撞擊障礙物，因此過濾效率就高。經(jīng)驗表明，對于高效過濾器，風(fēng)速減少一半，粉塵的透過率會降低近一個數(shù)量級(效率數(shù)值增加一個9)，風(fēng)速增加一倍，透過率會增加一個數(shù)量級(效率降低一個9)。與擴(kuò)散的效果類似，當(dāng)過濾材料帶靜電時(駐極體材料)，粉塵在濾材中滯留的時間越長，被材料吸附的可能性就越大。改變風(fēng)速，帶靜電材料的過濾效率會明顯改變，線路板無塵車間裝修公司。如果你知道材料上有靜電，進(jìn)行空調(diào)系統(tǒng)設(shè)計時就應(yīng)該盡可能地減少通過每只過濾器的風(fēng)量。對于以慣性機(jī)理為主的大顆粒粉塵，根據(jù)傳統(tǒng)理論，風(fēng)速降低后，粉塵與纖維碰撞的幾率會減少，過濾效率會隨之降低。但在實踐中這種影響并不明顯，因為風(fēng)速小了，線路板無塵車間裝修公司，纖維對粉塵的反彈力也小了，線路板無塵車間裝修公司，粉塵更容易被粘住。萬級凈化車間室內(nèi)空氣參數(shù)要求：新風(fēng)量大。由于這類車間內(nèi)，人員比較多，需求比較大。線路板無塵車間裝修公司</p><div

style="text-indent:25px">建造一個凈化車間的的前提條件，就是要選擇一家專業(yè)可靠的凈化工程公司，但如今隨著潔凈技術(shù)的廣泛應(yīng)用，市面上從事凈化工程的公司也變的越來越多，要從中選擇一家靠譜的凈化公司需要花費(fèi)一份功夫，下面小編就針對這一問題，給大家講解下如何一家專業(yè)可靠的凈化工程公司！選擇凈化工程公司四要素：一是價格，貨比三家，當(dāng)您收到各個凈化公司的報價時，看看報價是否過低或偏高。價格過低可能材料不佳，服務(wù)不佳，價格偏高就不用說了。二看設(shè)計，正規(guī)的凈化工程公司，設(shè)計依據(jù)充分，可根據(jù)客戶的使用情況做可以合適的設(shè)計。三要看重性價比，建議去報價的凈化工程公司實地考察一下，綜合評判凈化公司的實力，現(xiàn)在凈化市場存在很多亂象，比如以次充好，簡化安裝工藝等等，正規(guī)的凈化工程公司，不會因為眼前的蠅頭小利失去良好的信譽(yù)度?？梢院?、看凈化工程裝修公司工程案例，了解其設(shè)計水平和裝修水平，檢查驗收報告，觀察彩鋼板門窗的細(xì)節(jié)，風(fēng)量大小，彩鋼板與彩鋼板拼接處等等。</p><p style="text-indent:25px">亂流無塵車間原理：亂流無塵車間和單流無塵車間的不同在于從來流到出流（從送風(fēng)口到回風(fēng)口）之間氣流的流通截面是變化的，無塵車間截面大得多，因而不能在全室截面或者在全室截面或者在全室工作區(qū)截面形成均速氣流。所以，送風(fēng)口以后的流線彼此有很大或者越來越大的夾角，曲率半徑很小，氣流在室內(nèi)不可能以單一方向流動，將會彼此撞擊，將有回流、旋渦產(chǎn)生。這就決定亂流無塵車間的流態(tài)實質(zhì)是：突變流；非均勻流。這比用紊流來描述亂流無塵車間更確切、更較全。紊流主要決定于雷諾數(shù)，也就是主要受流速的影響，但是如果采用一個高效過濾器頂送的送風(fēng)形式，則即使流速極低，也要產(chǎn)生上述各種結(jié)果，這就因為它是一個突變流和非均勻流。因此這種情況下不僅有流層之間因紊流流動而發(fā)生的摻混，而且還有全室范圍內(nèi)的大的回流、旋渦所發(fā)生的摻混。所以，概括地說，亂流無塵車間的作用原理是：當(dāng)一股干凈氣流從送風(fēng)口送入室內(nèi)時，迅速向四周擴(kuò)散、混合，同時把差不多同樣數(shù)量的氣流從回風(fēng)口排走，這股干凈氣流稀釋著室內(nèi)污染的空氣，把原來含塵濃度很高的室內(nèi)空氣沖淡了，一直達(dá)到平衡。所以氣流擴(kuò)散得越快，越均勻，稀釋的技果就越好。萬級凈化車間室內(nèi)空氣參數(shù)要求：溫濕度要求：溫度一般為24+2℃，相對濕度為55+5%。</p><div

style="text-indent:25px">潔凈空調(diào)與一般空調(diào)的區(qū)別主要表現(xiàn)在以下幾個方面：（1）主要參數(shù)控制：一般空調(diào)側(cè)重溫度、濕度、新鮮空氣量和噪聲控制，而潔凈空調(diào)則側(cè)重控制室內(nèi)空氣的含塵量、風(fēng)速和換氣次數(shù)。在溫、濕度有要求的房間，溫、濕度也是主要控制參數(shù)。對生物凈化工程，含菌量是主要的控制參數(shù)之一。（2）空氣過濾手段：一般空調(diào)有的只有粗效一級過濾，要求高的是粗效、中效兩級過濾處理。而潔凈車間空調(diào)則要求粗、中、高效三級過濾或粗、中、亞高效三級過濾。同時，為了消除室內(nèi)排風(fēng)對大氣環(huán)境的影響，需依據(jù)不同的情況在排風(fēng)系統(tǒng)設(shè)排風(fēng)過濾或排風(fēng)凈化處理。（3）室內(nèi)壓力要求：一般空調(diào)對室內(nèi)壓力要求不嚴(yán)。而潔凈廠房空調(diào)為了避免外界污染空氣的滲入（內(nèi)部污染物逸出）或不同潔凈廠房（區(qū)）不同物質(zhì)的相互影響，對不同潔凈車間（區(qū)）的壓差均有不同的要求。（4）避免外界污染：為了避免被外界污染，潔凈空調(diào)系統(tǒng)材料和設(shè)備的選擇、加工工藝、加工安裝環(huán)境、設(shè)備部件的儲存環(huán)境等，均有特殊要求?，F(xiàn)在凈化市場存在很多亂象，比如以次充好，簡化安裝工藝等等。百級無塵車間施工哪家好</p><p style="text-indent:25px">無塵車間中的圓弧墻角、門、窗框等一般采用**凈化**型材制造。線路板無塵車間裝修公司</p><p style="text-indent:25px">無塵車間對人體可能產(chǎn)生的危害有以下幾個方面：1.可能缺氧,因為無塵車間是一個封閉的空間,只靠空調(diào)機(jī)組按一定風(fēng)量送入新鮮空氣,所以無塵車間可容納的人數(shù)是有限制的,如果超出這個人數(shù)限制,可能造成氧氣不夠用的狀況,長期在缺氧狀態(tài)下工作,可能造成人員感覺不適甚至頭暈.但只要嚴(yán)格控制進(jìn)入人數(shù),就可以保證人員安全.2.內(nèi)部生產(chǎn)工藝使用或產(chǎn)生的有毒有害氣體.有些焊接、清洗工位,因為使用了焊錫膏、清洗劑等含有有害化學(xué)物質(zhì),生產(chǎn)過程中可能會揮發(fā)出有毒有害的氣體,所以必須安裝使用合適的排風(fēng)排氣系統(tǒng),將產(chǎn)生的氣體及時排出室外.只要排風(fēng)系統(tǒng)安裝得當(dāng),風(fēng)機(jī)功率足夠,有害氣體能夠及時排出,對人體就不會造成危害.3.對電子行業(yè)的無塵車間來說,看你使用的設(shè)備是否有高輻射,比如射線探傷設(shè)備,必須有相應(yīng)的防護(hù)措施,避免人員傷害;4.完備的消防及疏散設(shè)施.無塵室空間相對封閉,必須按照要求配置滅火系統(tǒng),例如足夠的排風(fēng)排煙設(shè)施,滅火器和消火栓,以及保證疏散通道的通暢,否則在發(fā)生緊急情況時,人員無法及時疏散,相對普通車間會造成比較大的傷亡.只要無塵室的只要各項措施做到位,無塵無塵車間對人體沒有什么傷害。線路板無塵車間裝修公司</p></p><br
