Taw qhia rau Zin kev paub, yuav ua li cas yog hlau zinc synftized?
Zinc yog cov tshuaj lom neeg. Nws lub cim tshuaj lom yog ZN, thiab nws tus lej atomic yog 30. Nws yog nyob rau lub sijhawm plaub thiab pab pawg ⅱb ntawm lub rooj noj tshuaj. Zinc yog lub teeb ci hloov cov hlau thiab plaub "hom" hlau. Hauv kev lag luam niaj hnub, zinc yog irreplaceable hauv roj teeb raug thiab yog ib qho hlau tseem ceeb heev. Ib qho ntxiv, Zinc tseem yog ib qho ntawm cov ntsiab tseem ceeb rau tib neeg lub cev thiab ua ib qho tseem ceeb tshaj plaws.
Zinc yog qhov nyuaj rau hlawv hauv huab cua thiab emits lub teeb dawb dawb hauv oxygen. Muaj ib txheej ntawm zinc oxide nyob rau saum npoo ntawm zinc, uas emits emits dawb haus luam yeeb thaum nws hlawv. Lub ntsiab tivthaiv ntawm cov pa luam yeeb dawb yog zinc oxide, uas tsis tsuas yog thaiv cov nplaim hluav taws, tab sis kuj cuam tshuam cov xim ntawm cov nplaim taws los ua lub teeb daj. Zinc yooj yim yog soluble hauv cov kua qaub thiab tuaj yeem hloov tau cov nyiaj kub, nyiaj, thiab lwm yam los ntawm kev daws. Cov yeeb yaj kiab oxide ntawm Zinc muaj lub siab melting taw tes, tab sis lub ntsiab lus melting ntawm nws yog xim hlau zinc yog tsawg heev. Yog li cua sov lub zinc flukas rau ntawm lub teeb dej cawv yuav yaj thiab muag zinc plaub ya ri, tab sis tsis poob qis, yog vim muaj cov yeeb yaj kiab oxide. Zinc yog tsuas yog siv nyob rau hauv cov hlau, metallurgy, machinery, tshuab, tshuaj, kev lag luam lub teeb, tub rog thiab cov chaw ua tub rog.
Daws daws teeb meem:
1. Nqus tsev 360G ntawm nws yog xim hlau zinc thiab maj mam ntxiv rau nws rau 3340ML ntawm 15% cov sulfuric acid kua, thiab cua sov rau li 70 ° C rau cov tshuaj tiv thaiv. Thaum H2 tsis muaj ntau dhau, dilute nrog 1200ml ntawm cov dej los npaj cov tshuaj sulfate, noj tawm 50ml, thiab siv cov so rau kev siv tom qab. 4g ntawm sodium carbonate tau ntxiv rau 50ml ntawm cov tshuaj diluputed, thiab precipitated zinc carbonate precipion tau ntxuav peb zaug nrog dej (300mL txhua lub sijhawm) rau kev siv. Dissolve 7.5 g ntawm ferrous sulfate heptahydrate hauv 500 ml ntawm cov dej, thiab ntxiv 30% Ntxiv cov npaj cov hlau sulfate daws kom tau cov xim saum toj no, thiab ntxiv rau cov khoom siv zuaj, tom qab cua sov kom sov Tom qab daws tau meej, lim nws. [Tshem tawm ntawm Fe (Oh) 3 precipitates nrog li, p, sb thiab lwm yam tsis txaus siab]. Lub filtrate yog electrolyzed thiab tus nqi py yog hloov kho kom ua rau congo liab me ntsis xiav. Thaum lub sij hawm electrolysis, siv tus nqi them siab dawb lossis zinc frey lossis zinc ntawm ob lub hluav taws xob yog 6v, thiab qhov ceev tam sim no yog nyob ntawm qhov kub ntawm electrolyte. Tom qab 200g ntawm zinc yog precipitated, lub electrolyte yuav tsum tau kho dua nrog cov hlau sulfate thiab zinc carbonate raws li cov txheej txheem saum toj no.
2. Kev npaj ntawm zinc tau npaj los ntawm smelting zinc sib xyaw zom zaws cov khoom siv tseem ceeb. Kev lag luam tsis muaj kev lag luam, ZNS feem ntau yog oxidized thiab calcined rau hauv ib tug oxide nrog zoo reactivity. Tom qab ntawd siv cov txheej txheem thermal txo thiab electrolysis txoj kev npaj zinc. Tus nqi them los ntawm zinc ci thaiv thiab cov hmoov av thee yog muab tso rau hauv cov tshuaj tiv thaiv zinc uas tau dhau los ntawm cov conduit, thiab cov hlau zinc yog ntes. Cov hlau zinc tau los ntawm hom no muaj cov ntsiab lus impurity. Kom tau purer zinc, nqus tsev distillation yog yuav tsum tau.
3. Daws cov zinc oxide hauv cov khoom muaj roj nrog sulfuric acid, tshem tawm cov hlau los ntawm cov tshuaj electrolytic, tom qab ntawd tso rau hauv cov khoom siv hluav taws xob nrog cov txhuas ua cov anode thiab txhuas phaj li cathode. Thaum lub sij hawm electrolysis, nws yog xim hlau zinc yog tso rau ntawm lub phaj aluminium thiab peeled tawm los ua ib yam khoom. Lub purity ntawm nws yog xim hlau DM tau ua los ntawm electrolysis tuaj yeem ncav cuag 99.99%.
