Khoom Taw Qhia
Cov Khoom Siv Lub Cev thiab Tshuaj.
Nrog rau qhov hnyav atomic ntawm 65.38; qhov ceev ntawm 7.14g / cm3, Zinc muaj cov yam ntxwv zoo kawg uas ua rau nws yog cov khoom siv tseem ceeb rau ntau yam kev siv. Nws muaj lub ntsiab lus yaj ntawm 419.53 ° C thiab lub ntsiab lus kub ntawm 907 ° C, ua kom muaj kev ruaj khov thiab kev ntseeg siab txawm tias nyob rau hauv cov xwm txheej hnyav. Hauv kev lag luam niaj hnub no, zinc yog ib qho hlau tsis muaj peev xwm hloov tau thiab tseem ceeb heev hauv kev tsim cov roj teeb. Tsis tas li ntawd, zinc yog ib qho ntawm cov ntsiab lus tseem ceeb uas ua lub luag haujlwm tseem ceeb heev hauv tib neeg lub cev.
Cov ntawv sib txawv:
Peb cov khoom zinc muaj nyob rau hauv cov granules, hmoov, ingots thiab lwm yam ntaub ntawv rau kev siv yooj yim thiab yooj yim rau ntau yam txheej txheem thiab daim ntawv thov.
Kev ua tau zoo tshaj plaws:
Peb cov zinc uas muaj purity siab lav qhov kev ua tau zoo tshaj plaws, ua tau raws li cov qauv zoo tshaj plaws thiab ua tau zoo tshaj qhov xav tau hauv txhua daim ntawv thov. Nws qhov purity tshwj xeeb ua kom muaj kev sib xws thiab kev ntseeg tau rau kev sib koom ua ke hauv koj cov txheej txheem.
Cov Kev Siv Thoob Plaws Kev Lag Luam
Kev Lag Luam:
Zinc feem ntau siv rau hauv kev tsim cov khoom siv hluav taws xob, roj teeb thiab cov hlau sib xyaw nuclear vim nws cov hluav taws xob zoo thiab thermal conductivity.
Hlau: Zinc muaj cov khoom zoo heev ntawm kev xeb hauv huab cua thiab feem ntau yog siv rau kev txheej saum npoo ntawm cov ntaub ntawv hlau thiab cov khoom siv hlau.
Kev Tsim Kho:
Zinc yog siv rau hauv kev tsim ntau yam khoom siv hauv tsev xws li ru tsev, phab ntsa vaj huam sib luag thiab qhov rai vim nws tiv taus xeb thiab zoo heev plasticity. Hauv cov ntaub ntawv hlau ru tsev, zinc yog qhov nyiam rau nws txoj kev tiv taus huab cua hnyav thiab kev puas tsuaj ntawm ozone.
Khoom Siv Hluav Taws Xob:
Nws yog siv dav hauv kev tsim ntau yam roj teeb thiab cov khoom siv hluav taws xob. Zinc kuj yog ib qho khoom siv tseem ceeb rau kev tsim cov khoom xws li transistors thiab capacitors.
Tej yam ib puag ncig thiab kev ruaj khov:
Nws siv tau rau kev kho cov pa phem thiab pov tseg cov khib nyiab, xws li ua ib qho tshuaj rau kev kho cov dej khib nyiab kom pab tshem tawm cov tshuaj lom thiab cov pa phem. Nws kuj tseem siv tau rau hauv cov vaj huam sib luag hnub ci, cov roj teeb cia khoom thiab cov roj teeb roj los txhim kho kev siv hluav taws xob thiab kev ruaj khov.
Kev kho kom zoo nkauj thiab kev kho mob:
Cov tshuaj zinc muaj zog tua kab mob thiab nws lub peev xwm los tswj cov roj ntawm daim tawv nqaij tau ua rau nws siv rau hauv cov khoom siv pleev ib ce xws li tshuaj pleev, tshuaj zawv plaub hau, tshuaj pleev kom txias thiab tshuaj pleev thaiv hnub. Tsis tas li ntawd, hauv kev lag luam tshuaj, zinc feem ntau siv rau hauv kev tsim cov tshuaj rau kev kho cov kab mob ntawm daim tawv nqaij.
Kev Ceev Faj thiab Kev Ntim Khoom
Yuav kom paub tseeb tias cov khoom zoo, peb siv cov txheej txheem ntim khoom nruj heev, suav nrog cov yas zaj duab xis nqus tsev lossis cov yas zaj duab xis polyester tom qab polyethylene nqus tsev, lossis iav raj nqus tsev. Cov kev ntsuas no tiv thaiv qhov huv thiab zoo ntawm zinc, tswj nws cov txiaj ntsig thiab kev ua tau zoo.
Peb cov zinc uas muaj cov khoom ntshiab yog ib qho pov thawj ntawm kev tsim kho tshiab, zoo thiab kev ua tau zoo. Txawm koj ua haujlwm hauv kev lag luam, kev tsim kho, hlau, ib puag ncig thiab kev ruaj khov lossis lwm qhov chaw uas xav tau cov ntaub ntawv zoo, peb cov khoom zinc tuaj yeem txhim kho koj cov txheej txheem thiab cov txiaj ntsig. Cia peb cov kev daws teeb meem zinc coj koj qhov zoo tshaj plaws - lub hauv paus ntawm kev nce qib thiab kev tsim kho tshiab.
