1. Cov yam ntxwv ntawm tooj liab sulfate cov tshuaj lom neeg muaj pes tsawg leeg ntawm tooj liab sulfate yog CUSO4. Nws muaj cov tooj liab ion (cu2 +) thiab ib qho ion sulfate ion (oo42-). Tooj liab sulfate muaj ntau yam ntxwv. Ua ntej, nws yog ib qho inorganic tooj liab fungicide. Nws cov xiav asymmetric triclinic crystal system muaj cov dej nqus dej zoo thiab yuav ua ke nrog dej los ua cov muaju. Tooj liab sulfate yog kev ruaj khov nyob ntawm chav tsev kub thiab yooj yim soluble hauv dej. Nws cov kua aquous yog acidic thiab muaj cov yam ntxwv ntawm cov muaj kua qaub thiab cov ntsev ua kom tsis muaj zog yog cov tshuaj muaj zog tsis muaj zog. Ib qho ntxiv, tooj sulfate kuj yooj yim rau deliquesce, tab sis nws tsis cuam tshuam nws txoj kev ua tau zoo. Tooj liab sulfate feem ntau yog siv los ua cov tshuaj tiv thaiv thiab muaj mob lom rau tib neeg thiab tsiaj txhu. Nyob rau hauv chav tsev kub thiab siab, tooj liab sulfate yog qhov ruaj khov heev thiab tsis cuam tshuam. Nws yuav maj mam poob cov siv lead ua hauv cov cua qhuav thiab tig dawb.
2. Hom thiab cov ntawv thov ntawm tooj liab sulfate: raws li cov ntsiab lus, nws tuaj yeem faib ua cov ncauj lus hauv qab no: 98% tooj liab sulfate, thiab 99% tooj liab sulfate. Nyob rau tib lub sijhawm, tooj liab sulfate tseem tuaj yeem faib ua kev lag luam tooj liab sulfate, thiab tshuaj lom neeg cov khoom siv tooj liab sulfate raws li qib. Hauv kev lag luam electroplating, tooj liab sulfate tuaj yeem siv rau tooj pob hluav taws xob electroplating hauv kev lag luam hluav taws xob thiab cov khoom siv engineering. Hauv kev ua liaj ua teb ntawm cov tshuaj tua kab thiab cov fungicides, tooj liab sulfate kuj tau siv tshuaj tua kab thiab cov fungicides los tiv thaiv thiab tswj hwm cov nroj tsuag nroj tsuag thiab kab tsuag kab. Tooj liab sulfate tuaj yeem siv nyob rau hauv kev npaj cov tshuaj tiv thaiv tshuaj dawb thiab tseem tuaj yeem siv ua mordant. Hauv cov ntsiab lus kho mob, tooj liab sulfate tuaj yeem siv los kho tooj liab, tooj liab tuaj yeem siv cov dej algae ntau dhau, cov pas dej, thiab ua luam dej. Cov tshuaj tiv thaiv cov tshuaj ntawm cov hlau nrog tooj liab sulfate tov yog li nram no: FE + CUSO4 = CU + reacts nrog tooj liab sulfate daws kom tsim tooj liab thiab ferrous sulfate. Qhov tshuaj tiv thaiv no yog hloov cov tshuaj tiv thaiv. Hlau hloov tooj liab hauv tooj liab sulfate los tsim tooj liab thiab ferrous sulfate.
3. Kev lim tshuaj ntawm cov txheej txheem muaj tooj liab sulfate:
Cov khoom siv raw kev sib tw: tso cov txhab tooj liab sulfate rau hauv lub tank, thiab ua kom sov rau 60 ~ 80 ℃ kom yaj tag.
Oxidation thiab imprivity tshem tawm: Ntxiv qhov tsim nyog ntawm oxidant, xws li nitrical peroxide, thiab oxidize lub impurities nyob rau hauv kev daws.
Pom: lim cov tshuaj oxidized kom tshem tawm cov khoom impurities. Kho P muaj nuj nqis: Ntxiv tus nqi tsim nyog ntawm alkali, calcium hydroxide, thiab lwm yam. Nag los: Precipition cov tshuaj kom ua tiav nag lossis daus hydroxide.
Ntxuav: ntxuav cov tooj liab nag los hydroxide kom tshem cov impurities nyob saum npoo. Kom qhuav: Qhuav ntxuav cov tooj liab hydroxide kom tshem tawm cov dej noo. Kev hlawv: hlawv cov tooj liab qhuav hydroxide rau kev rhuav tshem nws rau hauv tooj liab sulfate.
Cua txias: Txias lub hlawv cov tooj liab sulfate kom tau txais cov khoom lag luam tooj liab sulfate khoom. Hauv cov txheej txheem lim dej ntawm muaj tooj liab sulfate, cov theem saum toj no tuaj yeem hloov kho thiab ua kom zoo raws li cov xwm txheej tiag tiag. Ib qho ntxiv, lwm txoj kev siv lub cev kuj tseem tuaj yeem siv los txhim kho cov kev coj dawb huv thiab qhov zoo ntawm tooj liab sulfate.
