Kev Ntshiab Siab 5N txog 7N (99.999% txog 99.99999%) Selenium (Se)
Khoom Taw Qhia
Cov Khoom Siv Lub Cev thiab Tshuaj:
Selenium muaj qhov hnyav atomic ntawm 78.96; qhov ceev ntawm 4.81g / cm3 thiab 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 221 ° C; lub ntsiab lus kub ntawm 689.4 ° C, uas ua kom nws ruaj khov thiab ntseeg tau txawm tias nyob rau hauv cov xwm txheej hnyav.
Cov ntawv sib txawv:
Peb cov khoom selenium muaj nyob rau hauv cov granules, hmoov, blocks thiab lwm yam ntaub ntawv rau kev ywj pheej thiab yooj yim siv hauv ntau yam txheej txheem thiab daim ntawv thov.
Kev Ua Tau Zoo Tshaj Plaws:
Peb cov selenium purity siab lav qhov kev ua tau zoo tsis muaj qhov sib piv, 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 Ua Liaj Ua Teb:
Selenium yog ib qho tseem ceeb rau kev loj hlob ntawm cov nroj tsuag, thiab qhov tsis muaj selenium tuaj yeem ua rau cov qoob loo tsis loj hlob. Yog li ntawd, cov chiv selenium tuaj yeem txhim kho cov qoob loo thiab qhov zoo.
Kev tiv thaiv ib puag ncig:
Selenium tuaj yeem siv ua tus neeg sawv cev kho dej kom zoo kom tshem tawm cov pa phem hnyav ntawm dej, thiab kuj tseem siv tau rau hauv kev kho av thiab phytoremediation los pab txo cov pa phem hauv av thiab dej.
Kev Lag Luam:
Selenium muaj cov khoom photosensitive thiab semiconductor, thiab feem ntau yog siv los ua photocells, photoreceptors, infrared controllers, thiab lwm yam.
Kev lag luam hlau:
Selenium txhim kho cov khoom ua haujlwm ntawm cov hlau thiab feem ntau siv rau hauv kev lag luam metallurgical.
Kev Kho Mob:
Selenium muaj cov khoom antioxidant thiab anti-inflammatory, uas pab tiv thaiv kab mob plawv, mob qog noj ntshav, mob thyroid, thiab lwm yam. Nws kuj tseem tuaj yeem txhim kho lub cev tiv thaiv kab mob.
Kev Ceev Faj thiab Kev Ntim Khoom
Yuav kom ntseeg tau tias cov khoom muaj kev ncaj ncees, peb siv cov txheej txheem ntim khoom nruj, suav nrog cov yas zaj duab xis nqus tsev lossis cov yas zaj duab xis ntim tom qab polyethylene nqus tsev encapsulation, lossis iav raj nqus tsev encapsulation. Cov kev ntsuas no tiv thaiv qhov huv thiab zoo ntawm tellurium thiab tswj nws cov txiaj ntsig thiab kev ua tau zoo.
Peb cov selenium uas muaj purity siab yog ib qho pov thawj ntawm kev tsim kho tshiab, zoo thiab kev ua tau zoo. Txawm koj nyob hauv kev ua liaj ua teb, kev lag luam, kev tiv thaiv ib puag ncig lossis lwm yam haujlwm uas xav tau cov ntaub ntawv zoo, peb cov khoom selenium tuaj yeem txhim kho koj cov txheej txheem thiab cov txiaj ntsig. Cia peb cov kev daws teeb meem selenium muab rau koj nrog kev paub zoo dua - lub hauv paus ntawm kev nce qib thiab kev tsim kho tshiab.
