Zinc: Essence, Cov Cai thiab Kev Siv

1. Taw qhia txog Zinc Zinc Zinc, Tshuaj lom neeg ZN, atomic tooj 30, yog cov hlau hloov. Zinc tau dav faib hauv xwm thiab yog ib qho ntawm cov kab tseem ceeb hauv cov muaj sia muaj sia. Nws yog dav siv hauv kev lag luam tsim khoom, kev tsim kho, kev thauj mus los, tshuaj thiab lwm daim teb. Lub npe zinc los ntawm Latin "Zinco" Zinco "

2. Lub zog ntawm cov xim zinc thiab lus txhawb: ntshiab zinc yog silvery dawb nrog nws yog xim hlau luster. Nyob rau hauv huab cua, zinc deg yuav maj mam oxidize, sib sau ua yeeb yaj kiab grey-dawb xim oxide. Qhov ceev thiab melting point: lub ntom ntawm zinc yog li 7.14g / mel³ yog 419.5 ℃, thiab lub boiling point yog 907 ℃. Qhov no ua rau Zinc muaj cov khoom ua haujlwm zoo ntawm chav tsev kub thiab haum rau ntau cov txheej txheem raug tsim khoom. Ductility thiab conductivity: zinc muaj qee yam duction thiab tuaj yeem kos rau hauv cov ntawv sau, tab sis nws cov hluav taws xob, tab sis thermal thiab thermal thiab thermal thiab cov tooj liab thiab txhuas. Hardness and strength: Pure zinc has a low hardness, but its hardness and strength can be increased through alloying to meet the needs of different fields.

3. Tshuaj lom neeg ntawm zinc refle nrog oxygen: zinc yuav hnov ​​mob nrog oxygen nyob rau hauv huab cua los ua zinc oxide. 2ZN + O₂ = 2ZNO reacts nrog acids: zinc muaj peev xwm hnov ​​nrog cov kua qaub tsis xws li dilfroric acid los tsim kom muaj cov ntsev ua kom zoo nkauj thiab hydrogen. ZN + HAYSO₄ = ZMSSO₄ + H₂↑
ZN + 2hl = ZNCL₂ + H₂↑ RAWS NROG ALKALI: Zinc tuaj yeem tawm tsam nrog cov alkali muaj zog los tsim zinc hydoxide thiab hydrogen roj. ZN + 2NOHOH = NANKNO₂ + h₂↑ cov tshuaj tiv thaiv nrog cov tshuaj tsw qab, xws li cov ntsev tsis zoo, thiab lwm yam. Znso₄ = ZNSO₄ + CU
ZN + 2AGNO₃ = ZN (NOT₃ (NOT₃) ₂ + 2AG
4. Lub hav zoov daim ntawv thiab rho tawm ntawm zinc (1) muaj cov ntaub ntawv sphalerite: Zinc feem ntau muaj nyob hauv sphaalerite. Lub ntsiab tivthaiv ntawm sphaalerite yog zinc sulfide (Zns), uas feem ntau tseem muaj lwm yam khoom xws li hlau thiab txhuas. Lwm Yam Minerals: Zinc tseem muaj nyob rau hauv qee lwm yam zaub mov, xws li smithsonite (lub ntsiab lus tseem ceeb yog znos₃), thiab lwm yam. (2) Cov txheej txheem rho tawm thiab cov ine mined Los ntawm kuv li undergoes crushing, tshuaj ntsuam, kev hloov thiab lwm yam kev ua tiav, cov ore nrog cov ntsiab lus ntau dua zinc yog xaiv. Ci: Xaiv Ore yog ci los txhim kho kev txiav txim siab thiab qib ntawm ore. SMELTING: siv Pyrometallurgurgurgurgurgurgurgurgy los yog hydrometallurgurgy mus hloov zinc sulfide rau hauv xim hlau zinc. Pyrometallurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgurgy suav nrog cov kauj ruam xws li distillation thiab txo qis; Hydrometallurgurgurgurgurge feem ntau siv tshuaj ntxuav tshuaj kom yaj zinc los ntawm oree. 2Zns + 3O₂ = 2ZNO + 2SO₂↑
ZNO + C = ZN + CO
5. Kev siv ntawm zinc (1) Daim ntawv thov ntawm Galvanizing hauv Galvanizing hauv Galvanizing ntawm cov hlau los txhawm rau txhim kho cov hlau corrosion tsis kam ntawm cov hlau. Piv txwv li, galvanized hlau daim ntawv, galvanized steel yeeb nkab, thiab lwm yam roj teeb: Zinc ua lub luag haujlwm tseem ceeb hauv kev tsim khoom roj teeb. Piv txwv li, cov roj teeb qhuav, chaw cia khoom, thiab lwm yam siv zinc raws li cov khoom tsis zoo electrode. Alloy Khoom: Zinc Alloy muaj cov khoom zoo thiab cov neeg kho tshuab thiab tau siv dav hauv kev tsim ntau qhov chaw thiab dai kom zoo. (2) Daim ntawv thov hauv kev lag luam ntau lawm steel smill hlau: zinc yog siv los ua deoxidizer thiab demulfurizer hauv cov qauv hlau smelting, uas tuaj yeem txhim kho cov hlau thiab ua tau zoo ntawm cov hlau. Tshuaj Kev Lag Luam: Zinc tau dav hauv kev lag luam tshuaj, thiab lwm yam. Raws li koom nrog hauv txoj cai ntawm kev ua yeeb yam enzyme thiab txhim kho kev tiv thaiv kab mob. Yog li ntawd, Zinc tseem muaj dav hauv cov teb kho mob, xws li saib xyuas zinc tsis txaus thiab txhim kho kev tiv thaiv.
