Tib neeg raug rau txhuas yog qhov kev zam tsis tau thiab, tej zaum, inestimable. Aluminium's free metal cation, Alaq(3+), yog cov tshuaj lom neeg lom zem heev thiab muaj lom zem heev aluminium tsis yog qhov tseem ceeb thiab tseem ceeb tshuaj lom.
Aluminium puas yog hlau?
Aluminium yog cov hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Nws muaj nyob rau hauv ib puag ncig ua ke nrog lwm cov khoom xws li oxygen, silicon, thiab fluorine. raug rau txhuas feem ntau tsis muaj teeb meem, tab sis raug rau qib siab tuaj yeem ua rau muaj teeb meem loj.
Yuav ua li cas ntawm aluminium yog tshuaj lom?
Qib siab dua 60 µg / L qhia tias muaj kev nqus ntau ntxiv, qib ntshav qab zib siab tshaj 100 µg / Lmuaj feem cuam tshuam, thiab qib ntshav siab dua 200 µg / L feem ntau cuam tshuam nrog cov tsos mob ntawm kev kho mob. thiab tej yam tshwm sim ntawm toxicity.
Dab tsi yog qhov phom sij ntawm aluminium?
Cov kev tshawb fawb yav dhau los tau txuas nrog kev cuam tshuam rau cov qib siab ntawm aluminium rau neurotoxicity (kev noj qab haus huv cuam tshuam rau hauv nruab nrab lossis sab hauv lub paj hlwb lossis ob qho tib si), Alzheimer's disease, thiab mob qog noj ntshav mis.
Aluminium ua dab tsi rau koj lub hlwb?
Aluminium, raws li lub npe hu ua neurotoxicant, ua rau kev paub tsis meej thiab tuaj yeem ua rau Alzheimer's tus kab mob. Qhov laj thawj tseem ceeb yog tias txhuas tuaj yeem nkag mus thiab tso rau hauv lub hlwb. Muaj peb txoj hauv kev uas txhuas tuaj yeem nkag mus rau hauv lub hlwb los ntawm kev ua haujlwm hauv lub cev lossis qhov chaw ntawmabsorption.

Kuv puas tuaj yeem ua cov txhuas txhuas?
Koj tuaj yeem ua tau siv Aluminium braze kho cov kab nrib pleb, qhov, ntws, rivets, pob ntseg tawg, xov lossis fabricate aluminium, cam khwb cia txhuas, thiab cam khwb cia hlau sai, yooj yim, thiab muaj zog dua tshiab. Nws tsis nyuaj kiag li.
Puas yog lub dav hlau dav hlau ya mus rau hauv qhov chaw?
dav hlau tuaj yeem thiab tau ya mus rau hauv qhov chaw tau ntau dua 50 xyoo - txawm tias tsis zoo li koj pom hauv tshav dav hlau. Qhov ntawd yog vim cov dav hlau ib txwm xav tau huab cua rau ob qho tib si propulsion thiab nqa, thiab qhov chaw yog qhov tseem ceeb ntawm lub tshuab nqus tsev.
Cov hlau nplaum puas lo rau txhuas?
Cov lus teb zoo tshaj yog hais tias aluminium tsis sib nqus nyob rau hauv ib txwm muaj. Qhov no yog vim aluminium cuam tshuam nrog hlau nplaum. Tsis tas li, thaum raug cov hlau nplaum muaj zog, txhuas tuaj yeem sib nqus me ntsis txawm tias nws tsis pom cov hlau nplaum nyob rau hauv ib txwm muaj.
Qhov twg xeb txhuas lossis hlau?
Puas yog Aluminium Rust? Rusting yog ib hom kev xeb uas tshwj xeeb rau hlau thiab hlau(vim nws muaj hlau). Qhov tseeb, xeb yog lub npe nrov rau hlau oxide, thaum hlau los yog hlau sib txuas nrog oxygen thiab dhau oxidation. Yog li ntawd, aluminium tsis tuaj yeem xeb.
Puas yog txhuas tuaj yeem muaj zog li hlau?
Txhuas yog kwv yees li ib feem peb ntawm qhov hnyav ntawm cov hlau, txhais tau tias cov khoom tuaj yeem ua kom tuab thiab muaj zog dua thaum tseem txo qhov hnyav hauv tsheb thiab lwm yam kev siv. Raws li cov txheej txheem kev siv alloy thiab cov txheej txheem siv, phaus rau phaus txhuas tuaj yeem forged kom muaj zog yog tias tsis muaj zog dua li qee cov hlau.
