在設計(ji)潔凈(jing)實(shi)(shi)驗(yan)(yan)(yan)(yan)室時注(zhu)意哪些要(yao)點？設計(ji)說明(ming)：潔凈(jing)實(shi)(shi)驗(yan)(yan)(yan)(yan)室設計(ji)基本思路為(wei)經濟(ji)、實(shi)(shi)用(yong)。凈(jing)化要(yao)求(qiu)(qiu)級(ji)別為(wei)萬(wan)級(ji)。實(shi)(shi)驗(yan)(yan)(yan)(yan)室設計(ji)有一更、二更、風(feng)淋(lin)和(he)(he)緩(huan)沖等實(shi)(shi)驗(yan)(yan)(yan)(yan)前的準備工作(zuo)(zuo)。采用(yong)人和(he)(he)物(wu)流(liu)分開(kai)原(yuan)則，以減少(shao)實(shi)(shi)驗(yan)(yan)(yan)(yan)污染，保(bao)證(zheng)安全(quan)。1、本布(bu)置緊(jin)湊、合理，滿足了(le)(le)實(shi)(shi)驗(yan)(yan)(yan)(yan)室操作(zuo)(zuo)和(he)(he)空(kong)(kong)氣(qi)(qi)潔凈(jing)度等級(ji)要(yao)求(qiu)(qiu)，同(tong)時力(li)求(qiu)(qiu)科學性與經濟(ji)性的原(yuan)則，考慮(lv)實(shi)(shi)驗(yan)(yan)(yan)(yan)室要(yao)求(qiu)(qiu)和(he)(he)發展(zhan)及運(yun)行費用(yong)優。2、潔凈(jing)實(shi)(shi)驗(yan)(yan)(yan)(yan)室入(ru)口處設置風(feng)淋(lin)室，能有效(xiao)清除人體所帶灰塵，減少(shao)潔凈(jing)室的灰塵量(liang)，同(tong)時風(feng)淋(lin)室也起到了(le)(le)氣(qi)(qi)閘的作(zuo)(zuo)用(yong)，防止(zhi)不(bu)潔凈(jing)空(kong)(kong)氣(qi)(qi)由門(men)進入(ru)潔凈(jing)區。

在10萬(wan)級凈(jing)(jing)化車間(jian)中，PCB凈(jing)(jing)化工(gong)(gong)程公司，允許粉塵顆(ke)(ke)(ke)粒(li)(li)(li)(li)數(shu)為0.5百(bai)萬(wan)或以上的(de)(de)顆(ke)(ke)(ke)粒(li)(li)(li)(li)數(shu)量(liang)不(bu)得超過(guo)350萬(wan)顆(ke)(ke)(ke)，唐山PCB凈(jing)(jing)化工(gong)(gong)程，顆(ke)(ke)(ke)粒(li)(li)(li)(li)數(shu)大于或等于5微(wei)(wei)(wei)米(mi)的(de)(de)顆(ke)(ke)(ke)粒(li)(li)(li)(li)數(shu)不(bu)得超過(guo)20，000顆(ke)(ke)(ke)。0.5微(wei)(wei)(wei)米(mi)的(de)(de)概念是什么(me)？發束的(de)(de)直徑約為70-100微(wei)(wei)(wei)米(mi)，細菌(jun)的(de)(de)大小約為1微(wei)(wei)(wei)米(mi)至2微(wei)(wei)(wei)米(mi)。通過(guo)凈(jing)(jing)化空氣系(xi)統，大于或等于5微(wei)(wei)(wei)米(mi)的(de)(de)顆(ke)(ke)(ke)粒(li)(li)(li)(li)數(shu)量(liang)不(bu)應超過(guo)20，000。所以10萬(wan)級凈(jing)(jing)化車間(jian)的(de)(de)凈(jing)(jing)化程度(du)非常高。
