Dab tsi koj yuav tsum paub txog cov dej deionized?

Cov dej dej uas muaj kev phom sij ua haujlwm rau cov khoom siv hluav taws xob tseem ceeb hauv kev tsim cov tshuaj thiab cov cuab yeej siv los ntawm ultra- ntshiab, ntxhia- dej dawb. Cov txheej txheem deionization, uas tshem tawm cov qauv paug ionic, muab cov ntawv thov purity dej uas yuav tsum muaj rau daim ntawv thov kev siv nyiaj luv luv hauv kev tsim khoom lag luam.

Rau cov koom haum txiav txim siab siv DI dej daws teeb meem los yog nrhiav kev ua haujlwm tshwj xeeb muab cov kev qhia tshwj xeeb hauv cov kev ua tau zoo thiab kev siv khoom lag luam.

Dej Deionized yog dab tsi?

Dej deionized (DI dej) sawv cev rau cov dej huv huv ntawm cov dej ntawm txhua cov ntxhia thiab cov calcium, thiab magnesium. Qhov kev hloov kho tshiab uas pom cov nqi hluav taws xob uas pom ntawm cov chaw soj ntsuam kev tshawb fawb, thiab kev ua tiav ntawm cov kev ua tiav ntawm Iionic cov khoom noj lossis khoom siv ntev.

Thaum Di dej tsis muaj kev coj phem ua rau muaj kev tsis pom zoo xws li kev sim tshuaj thiab tshawb fawb thiab tsis haum rau kev noj haus tsis tu ncua. Cov txheej txheem deionization exioninates cov zaub mov tseem ceeb, muaj peev xwm ua rau muaj kev lom zem thiab muaj kev cuam tshuam kev noj qab haus huv yog tias noj ntev- lub sij hawm.

Txoj kev nplua cov dej ua haujlwm li cas?

Kev ua haujlwm deionization kev lag luam ion pauv pauv thev naus laus zis los tshem tawm cov ntxhia ntxhia cov av hauv cov dej. Cov txheej txheem uas siv cov khoom lag luam resin-} Txhaws resin mus tshem tawm qhov tsis zoo them ions (piv txwv li, chloride, sulfate). Dej ua tiav los ntawm no dual - theem kev ua haujlwm tawm hauv ionic paug, ua tiav "dealeized" kev faib tawm ".

Deionized dej vs. distilled dej

Deionized thiab distilled dej sawv cev rau ob qho kev ua kom huv si rau cov dej ua kom huv, txhua tus muaj yam ntxwv ua yeeb yam thiab cov khoom muaj nuj nqi. Distillation ua tiav purification los ntawm thermal theem sib cais {} vaporizing dej los tso tseg thiab cov kab mob sib xyaw thiab cov kab mob sib xyaw ua ke.

Conversely, deionization employs electrochemical ion exchange to selectively extract mineral ions while remaining ineffective against non-charged particulates. Qhov tseem ceeb tshaj plaws cov lus dag nyob rau hauv lawv cov kev ua kom huv, distillation's kev daws teeb meem siv tshuaj lom neeg lossis cov ntawv thov ua haujlwm raws li kev xav tau.
