超純水機(jī)是在反滲透技術(shù)的基礎(chǔ)上，添加了離子交換和終端處理技術(shù)。有些還有深度離子除鹽、超濾和UV光氧化作用設(shè)備，出來(lái)的水水質(zhì)優(yōu)于國(guó)標(biāo)實(shí)驗(yàn)室一級(jí)用水的水質(zhì)要求。天然水中常見(jiàn)雜質(zhì)包括可溶性無(wú)機(jī)物、有機(jī)物、顆粒物、微生物、可溶性氣體等。超純水機(jī)就是要盡可能徹底地去處這些雜質(zhì)。目前常用凈化水質(zhì)的工藝方法有蒸餾法、反滲透法、離子交換法、過(guò)濾法、吸附法、紫外氧化法等。超純水機(jī)一般可以將水的純化過(guò)程大致分為4大步，預(yù)處理(初級(jí)凈化)、反滲透(生產(chǎn)出純水)，離子交換和終端處理。</p><p style="text-indent:25px"> EDI用的膜和反滲透用的膜很不相同，反滲透用的膜允許小顆粒的分子污染物和離子以及水通過(guò)，而EDI膜象離子交換樹(shù)脂一樣是用聚苯乙烯材料制作的，只允許帶適當(dāng)電荷的離子通過(guò)，水基本上不能通過(guò)。樹(shù)脂通過(guò)水的分離持續(xù)的再生。在電場(chǎng)中，給水中的水分子被分離成H+和OH- ，被異性電荷相吸，H+通過(guò)陽(yáng)陽(yáng)樹(shù)脂移向陰極的方向，OH-通過(guò)陰樹(shù)脂移向陽(yáng)極的方向。這種H+和OH-的遷移再生了樹(shù)脂，陽(yáng)膜允許H+通過(guò)進(jìn)入濃水室，陰膜允許 OH-通過(guò)也進(jìn)入濃水室，H+和OH-結(jié)合生成生產(chǎn)的水。濃水室中自己水的流動(dòng)將帶走水中的陰陽(yáng)離子。膜阻止帶相反電荷的離子的進(jìn)入淡水室在水流通過(guò)淡水室的過(guò)程中，離子被樹(shù)脂去處，所以膜的有效側(cè)(淡水室)就會(huì)產(chǎn)生純水。固定床離子交換是一種較常用的離子交換方式。</p><div

style="text-indent:25px">隨著工業(yè)化的普及，超純水在電子工業(yè)主要是電子元器件生產(chǎn)中的重要作用日益突出，超純水水質(zhì)已成為影響電子元器件產(chǎn)品質(zhì)量、生產(chǎn)成品率及生產(chǎn)成本的重要因素之一，水質(zhì)要求也越來(lái)越高。在電子元器件生產(chǎn)中，超純水主要用作清洗用水及用來(lái)配制各種溶液、漿料，不同的電子元器件生產(chǎn)中超純水的用途及對(duì)水質(zhì)的要求也不同。在電解電容器生產(chǎn)中，鋁箔及工作件的清洗需用超純水，如水中含有氯離子，電容器就會(huì)漏電。在電子管生產(chǎn)中，電子管陰極涂敷碳酸鹽，如其中混入雜質(zhì)，就會(huì)影響電子的發(fā)射，進(jìn)而影響電子管的放大性能及壽命，因此其配液要使用超純水。反滲透反滲透是使用一個(gè)高壓泵對(duì)高濃度溶液提供比滲透壓差大的壓力。黃浦區(qū)超純水設(shè)備銷售價(jià)格</p><p
