DI (deionized) dej yog ib hom dej huv uas tau dhau los ntawm cov txheej txheem tshem tawm ions thiab cov zaub mov los ntawm nws. Nws yog feem ntau siv hauv kev lag luam xws li tshuaj, khoom siv hluav taws xob thiab lwm cov txheej txheem tsim khoom uas muaj cov impurities tuaj yeem cuam tshuam qhov zoo ntawm cov khoom kawg.
Cov txheej txheem ntawm deionizing dej koom nrog kev siv cov ion txauv resin txaj uas zoo ions raug pauv rau hydrogen ions thiab tsis zoo ions raug pauv rau hydroxide ions. Qhov no ua rau tshem tawm feem ntau ntawm cov zaub mov thiab lwm yam impurities uas yuav muaj nyob hauv dej.
Cov dej deionized feem ntau yog siv los ua cov kuab tshuaj rau ntau lub chaw kuaj thiab cov ntawv thov kev lag luam uas qhov purity ntawm cov dej yog qhov tseem ceeb. Nws kuj tseem siv los ua cov tshuaj yaug rau kev ntxuav zaum kawg ntawm chav kuaj iav, ua cov khoom siv rau cov tshuaj reagents, thiab ua cov tshuaj yaug rau cov khoom siv hluav taws xob.
Hauv kev lag luam kws tshuaj, dej deionized yog siv los tsim cov tshuaj raws li cov cab kuj lossis hnyav. Nws kuj tseem siv rau hauv kev tsim cov tshuaj txhaj tshuaj thiab lwm yam khoom siv kho mob.
Deionized dej kuj tseem siv hauv kev lag luam tshuaj pleev ib ce rau kev tsim cov tshuaj zawv plaub hau, tshuaj kho mob thiab lwm yam khoom siv tu tus kheej. Nws feem ntau yog siv los ua lub hauv paus rau kev tsim cov khoom lag luam uas xav tau qib siab ntawm purity.
Kev lag luam zaub mov thiab dej haus kuj tseem siv dej deionized hauv ntau daim ntawv thov. Nws yog siv rau hauv kev tsim cov dej qab zib, npias thiab lwm yam dej haus kom ntseeg tau tias cov khoom kawg tsis muaj impurities uas yuav cuam tshuam rau qhov tsw lossis zoo ntawm cov dej haus.
Hauv kev xaus, dej deionized yog dej huv uas muaj ntau yam siv hauv ntau yam lag luam. Nws cov purity ua rau nws tsim nyog hnyav, nqa thiab yaug cov tshuaj rau ntau qhov chaw kuaj thiab kev lag luam. Kev lag luam tshuaj, tshuaj pleev ib ce, thiab zaub mov thiab dej haus tsuas yog qee qhov piv txwv uas cov dej deionized yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom.
