style="text-indent:25px">電子無(wú)塵車(chē)間：所謂半導(dǎo)體電子潔凈車(chē)間，指的是潔凈度在10萬(wàn)級(jí)標(biāo)準(zhǔn)以上的車(chē)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(jì)算。在絕大多數(shù)情況下，無(wú)塵車(chē)間運(yùn)行中風(fēng)速越低，過(guò)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(dòng))明顯，風(fēng)速低了，氣流在過(guò)濾材料中滯留的時(shí)間就長(zhǎng)一些，粉塵就有更多的機(jī)會(huì)撞擊障礙物，因此過(guò)濾效率就高。經(jīng)驗(yàn)表明，對(duì)于高效過(guò)濾器，風(fēng)速減少一半，粉塵的透過(guò)率會(huì)降低近一個(gè)數(shù)量級(jí)(效率數(shù)值增加一個(gè)9)，電子無(wú)塵車(chē)間設(shè)計(jì)價(jià)格，風(fēng)速增加一倍，透過(guò)率會(huì)增加一個(gè)數(shù)量級(jí)(效率降低一個(gè)9)。與擴(kuò)散的效果類(lèi)似，當(dāng)過(guò)濾材料帶靜電時(shí)(駐極體材料)，粉塵在濾材中滯留的時(shí)間越長(zhǎng)，被材料吸附的可能性就越大。改變風(fēng)速，帶靜電材料的過(guò)濾效率會(huì)明顯改變。如果你知道材料上有靜電，進(jìn)行空調(diào)系統(tǒng)設(shè)計(jì)時(shí)就應(yīng)該盡可能地減少通過(guò)每只過(guò)濾器的風(fēng)量。對(duì)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(huì)減少，過(guò)濾效率會(huì)隨之降低。但在實(shí)踐中這種影響并不明顯，因?yàn)轱L(fēng)速小了，電子無(wú)塵車(chē)間設(shè)計(jì)價(jià)格，電子無(wú)塵車(chē)間設(shè)計(jì)價(jià)格，纖維對(duì)粉塵的反彈力也小了，粉塵更容易被粘住。十萬(wàn)級(jí)凈化車(chē)間就是是指空氣潔凈度為十萬(wàn)級(jí)的潔凈車(chē)間。電子無(wú)塵車(chē)間設(shè)計(jì)價(jià)格</p><div
