3mg/l以下,電導率小于0.

style="text-indent:25px">超純水是具有一定結(jié)構(gòu)的液體，雖然它沒有剛性，但它比氣態(tài)水分子的排列有規(guī)則得多。在液態(tài)水中，水的分子并不是以單個分子形式存在，而是有若干個分子以氫鍵締合形成水分子簇( H2O)，因此水分子的取向和運動都將受到周圍其他水分子的明顯影響。對于水的結(jié)構(gòu)還沒有肯定的結(jié)構(gòu)模型，目前被大多數(shù)接受的主要有3 種: 混合型、填隙式和連續(xù)結(jié)構(gòu)(或均勻結(jié)構(gòu))模型。超超純水指的是不含雜質(zhì)的H2O。從學術(shù)角度講，超超純水又名超純水，是指化學純度極高的水，其主要應用在生物、化學化工、冶金、宇航、電力等領(lǐng)域，但其對水質(zhì)純度要求相當高，所以一般應用較普遍的還是電子工業(yè)。</p><p

至6B1146.11-89，超純水的電子級水分為五個級別，I級、 I級、I級、IV級和V級，超純水的水質(zhì)標準中所規(guī)定的各項指標的主要依據(jù)有: 1.微電子工藝對水質(zhì)的要求; 2.制水工藝的水平; 3.檢測技術(shù)的現(xiàn)狀。超純水在電子元器件生產(chǎn)中的重要作用日益突出，超純水水質(zhì)已經(jīng)成為影響電子元器件產(chǎn)品質(zhì)量、生產(chǎn)成品率以及生產(chǎn)成本的重要因素之-,水質(zhì)要求也是越來越高。在電子元器件的生產(chǎn)過程當中,超純水主要用作清洗用水以及用來配制各種溶液、漿料，不同的電子元器件在生產(chǎn)過程中超純水的用途及對水質(zhì)的要求也略有不同。長春超純水銷售價格</p><p
