DDS-1706 yog kev txhim kho ntsuas kev ua haujlwm; Raws li DDS-307 ntawm kev ua lag luam, nws tau ntxiv nrog lub tshuab nqus dej tsis siv neeg muaj nuj nqi, nrog cov nqi siab-ua tau zoo piv. Nws tuaj yeem yog dav siv rau kev saib xyuas qhov tseem ceeb ntawm cov kev daws teeb meem, kev lag luam ib puag ncig, kev lag luam tshuaj, khoom noj khoom haus, khoom noj khoom haus.

Kev coj uayog kev ntsuas ntawm dej lub peev xwm kom dhau hluav taws xob ntws. Lub peev xwm no ncaj qha ntsig txog kev xav txog e / ions hauv dej
1. Cov kev coj ua no los ntawm cov ntsev ua thiab cov ntaub ntawv inorganic xws li alkalis, chlorides, sulfides thiab cov pa roj carbon monoxide
2. Qhov sib xyaw uas yaj tau rau hauv Eల ions kuj tseem hu ua electrolytes 40. Qhov ntau tshaj plaws uas muaj, qhov siab dua ntawm cov dej. Ib yam li ntawd, lub me dua eons uas nyob hauv dej, qhov tsawg dua nws yog. Distilled lossis deionized dej tuaj yeem ua raws li insulator vim nws qhov tsawg heev (yog tias tsis yog qhov tsis zoo) conductivity tus nqi. Dej hiav txwv, ntawm qhov tod tes, muaj kev coj ua zoo heev.
Ions kev hluav taws xob ua rau lawv cov nqi tsis zoo thiab tsis zoo
Thaum electrolytes yaj hauv dej, lawv faib rau hauv qhov raug them siab (cation) thiab tsis zoo (anion) hais. Raws li cov tshuaj yeeb yaj kiab sib cais hauv dej, qhov ntau ntawm txhua qhov zoo thiab tsis zoo them nqi. Qhov no txhais tau tias txawm tias qhov kev coj ua ntawm cov dej ntxiv nrog ntxiv ions, nws tseem nyob hauv nruab nrab ntawm nruab nrab 2
