style="text-indent:25px">去離子水/超純水在電子工業(yè)主要是線路板、電子元器件生產(chǎn)中的重要作用日益突出，去離子/超純水水質(zhì)已成為影響線路板、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，去離子水/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)中純水的用途及對(duì)水質(zhì)的要求也不同。在晶體管、集成電路生產(chǎn)中，超純水主要用于清洗硅片，另有少量用于藥液配制，硅片氧化的水汽源，部分設(shè)備的冷卻水，配制電鍍液等。集成電路生產(chǎn)過(guò)程中的80%的工序需要使用高純水清洗硅片，水質(zhì)的好壞與集成電路的產(chǎn)品質(zhì)量及生產(chǎn)成品率關(guān)系很大。水中的堿金屬（K、Na等）會(huì)使絕緣膜耐壓不良，舟山純水設(shè)備大概多少錢，重金屬（Au、Ag、Cu等）會(huì)使PN結(jié)耐壓降低，Ⅲ族元素（B、Al、Ga等）會(huì)使N型半導(dǎo)體特性惡化，Ⅴ族元素（P、As，舟山純水設(shè)備大概多少錢、Sb等）會(huì)使P型半導(dǎo)體特性惡化，水中細(xì)菌高溫碳化后的磷（約占灰分的20-50%）會(huì)使P型硅片上的局部區(qū)域變?yōu)镹型硅而導(dǎo)致器件性能變壞，水中的顆粒（包括細(xì)菌）如吸附在硅片表面，舟山純水設(shè)備大概多少錢，就會(huì)引起電路短路或特性變差。超純水設(shè)備是采用預(yù)處理、反滲透技術(shù)、超純化處理以及后級(jí)處理等方法。舟山純水設(shè)備大概多少錢</p><div

style="text-indent:25px">一般水處理設(shè)備都是設(shè)計(jì)為全自動(dòng)運(yùn)行，操作簡(jiǎn)便。為了長(zhǎng)期有效的保證系統(tǒng)正常出水及壽命的延長(zhǎng)，純水設(shè)備需要嚴(yán)格執(zhí)行正確的維護(hù)保養(yǎng)方法?，F(xiàn)在為大家分享一下純水設(shè)備日常使用中的維護(hù)方法。一．進(jìn)水水質(zhì)嚴(yán)格控制進(jìn)水水質(zhì)，保證裝置在符合進(jìn)水指標(biāo)要求的水質(zhì)條件下進(jìn)行，進(jìn)水水質(zhì)不符合要求，極容易造成反滲透膜的污堵，使得耗材很快失效，嚴(yán)重影響出水水質(zhì)。二．反滲透的總進(jìn)水量反滲透的總進(jìn)水量由RO進(jìn)水調(diào)節(jié)閥來(lái)控制，如果反滲透進(jìn)水量沒(méi)有變化，則不要亂動(dòng)RO進(jìn)水調(diào)節(jié)閥，嚴(yán)禁全開(kāi)或全閉。RO濃排調(diào)節(jié)閥用來(lái)調(diào) 整系統(tǒng)回收率，如回收率沒(méi)有變化，則不要亂動(dòng)濃排調(diào)節(jié)閥，一定禁止全開(kāi)或全閉。</p><p style="text-indent:25px"> 一般來(lái)說(shuō)，純水設(shè)備的產(chǎn)水量絕大多數(shù)都是按照反滲透膜在25攝氏度進(jìn)水溫度下的標(biāo)準(zhǔn)來(lái)衡量的。如果您想選擇純水設(shè)備，一定要考慮到氣溫的變化，一般反滲透膜在使用后期一般都會(huì)出現(xiàn)水量降低等影響因素，所以一定放大需求產(chǎn)水量的1-2倍作為考慮。作為超純水的終端處理系統(tǒng)主要采用先進(jìn)的連續(xù)電除鹽簡(jiǎn)稱EDI技術(shù)或混床進(jìn)一步去除水中的各種離子。EDI是利用混合離子交換樹(shù)脂吸附給水中的陰陽(yáng)離子，同時(shí)這些被吸附的離子又在直流電壓的作用下，分別透過(guò)陰陽(yáng)離子交換膜而被去除的過(guò)程，在運(yùn)行的過(guò)程中持續(xù)的對(duì)樹(shù)脂進(jìn)行再生，與傳統(tǒng)設(shè)備相比體積比較小，維護(hù)費(fèi)用低。純水設(shè)備水處理的系統(tǒng)所選定的工藝基本可分為預(yù)處理系統(tǒng)、深度處理系統(tǒng)及終端處理系統(tǒng)三部分。</p><div

通過(guò)對(duì)反滲透設(shè)備入水管路排查，發(fā)現(xiàn)引起鐵離子增多的原因是增壓泵的使用。引入增壓泵是為了保證設(shè)備入水有足夠的壓力，以滿足砂濾的壓力需要，并保證高壓泵有足夠的啟動(dòng)壓力。但是原水含鹽量高達(dá)1.5g/L，不適當(dāng)?shù)倪x用增壓泵使得增壓泵迅速腐蝕，引起大量鐵離子進(jìn)入管路。而該設(shè)備根據(jù)原水進(jìn)行的設(shè)計(jì)，并沒(méi)有安裝處理鐵離子的裝置，造成了突然引入的鐵離子影響了設(shè)備的安全運(yùn)行。停止使用增壓泵，并清洗了壓力保護(hù)開(kāi)關(guān)的過(guò)水管路后，設(shè)備恢復(fù)正常運(yùn)行。通過(guò)故障現(xiàn)象分析，造成反滲透純水設(shè)備無(wú)法正常啟動(dòng)以及保安過(guò)濾器堵塞的原因是原水中鐵離子增加。這些鐵離子在原水中為還原態(tài)的亞鐵離子，可以溶于水中。這些水經(jīng)過(guò)保安過(guò)濾器吸附或積存在壓力開(kāi)關(guān)的管路中，在設(shè)備停機(jī)后被空氣中的氧氣氧化，變成了難溶于水的三價(jià)鐵不溶物，造成了保安過(guò)濾芯和管路的堵塞，影響了反滲透純水設(shè)備的正常運(yùn)行。純化水設(shè)備能夠滿足各行業(yè)需求的用水標(biāo)準(zhǔn)。舟山純水設(shè)備大概多少錢</p><p
