1. Hauv kev sim tshuaj lom neeg thiab tshuaj xyuas tshuaj
Raws li qhov chaw ntawm tooj liab ions: Nws yog ib qho reagent rau muab tooj liab ions. Hauv ntau qhov kev sim, tooj liab ions yuav tsum tau koom nrog hauv cov tshuaj tiv thaiv. Piv txwv li, hauv kev kawm txog kev hloov pauv hlau, cov tshuaj tiv thaiv redox, thiab nag lossis daus, tooj liab ions tuaj yeem yooj yim tau los ntawm kev ua kom tooj liab chloride dihydrate.
Rau kev soj ntsuam zoo thiab muaj nuj nqis: Cov phenomena uas ua los ntawm nws cov tshuaj tiv thaiv nrog lwm yam tshuaj (xws li nag lossis daus, xim hloov, thiab lwm yam) tuaj yeem siv los txheeb xyuas qhov muaj qee yam ions. Piv txwv li, tooj liab ions lossis sulfur ions tuaj yeem kuaj tau los ntawm kev ua haujlwm nrog hydrogen sulfide () los tsim cov tooj liab sulfide dub () nag lossis daus; Nws kuj tseem tuaj yeem siv rau kev ntsuas ntau, xws li txiav txim siab qhov concentration ntawm tooj liab ions hauv cov tshuaj los ntawm complexometric titration thiab lwm txoj kev.
2. Hauv kev lag luam
Kev lag luam electroplating: Hauv cov txheej txheem ntawm tooj liab electroplating, tooj liab chloride dihydrate yog ib qho tseem ceeb ntawm cov tshuaj electroplating. Thaum lub sij hawm electroplating, tooj liab ions yuav raug txo thiab tso rau ntawm qhov chaw ntawm cov khoom plated nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb los ua ib tug uniform tooj liab plating txheej, uas txhim kho cov conductivity, hnav tsis kam thiab zoo nkauj ntawm cov khoom.
Kev luam ntawv thiab dyeing kev lag luam: Nws tuaj yeem siv los ua mordant. Mordants tuaj yeem pab dyes ua kom zoo dua rau cov ntaub thiab txhim kho cov nyhuv dyeing thiab ceev ceev. Nyob rau hauv cov txheej txheem luam ntawv thiab dyeing, tooj liab chloride dihydrate tuaj yeem ua ntej ua ke nrog cov ntaub thiab tom qab ntawd cuam tshuam nrog cov xim, kom cov xim tuaj yeem txuas nrog cov ntaub fiber ntau.
3. Hauv kev ua liaj ua teb
Fungicide: Copper chloride dihydrate tuaj yeem siv los ua cov tshuaj tua kab mob. Tooj liab ions muaj inhibitory thiab tua cov teebmeem ntawm qee cov nroj tsuag kab mob. Nws tuaj yeem siv los kho cov noob, av lossis tshuaj tsuag rau saum npoo ntawm cov nroj tsuag kom tiv thaiv thiab tswj cov kab mob uas tshwm sim los ntawm cov kab mob fungi, kab mob, thiab lwm yam. Piv txwv li, nws muaj qee yam kev siv hauv kev tiv thaiv thiab tswj cov kab mob xws li txiv hmab txiv ntoo downy mildew.
4. Nyob rau hauv lub teb ntawm catalysis
Cov complexes nws cov ntaub ntawv tuaj yeem koom nrog cov tshuaj tiv thaiv raws li catalysts. Piv txwv li, nyob rau hauv ib co organic synthesis cov tshuaj tiv thaiv, tooj liab complexes muaj peev xwm catalyze tej yam tshwm sim, xws li catalytic oxidation cov tshuaj tiv thaiv los yog carbon-carbon bond tsim cov tshuaj tiv thaiv, los txhim kho efficiency thiab selectivity ntawm cov tshuaj tiv thaiv.
