11). Zinc toxicity tuaj yeem tshwm sim thaum ib tus neeg raug thiab ua pa cua daj cua dub ua los ntawm vuam lossis cua sov galvanized hlau. Rau kub-dipped galvanized steel qhov pom zoo kub siab tshaj plaws yog 392f ua ( 200 C ), ua ntej cov hlau ua rau muaj kev pheej hmoo toxicity.
Ib yam li ntawd, yog cua sov galvanized hlau tsis zoo?
Zoo li ntawd cua sov galvanized cov yeeb nkab mus rau qhov kub kub kub tso pa tawm ntawm zinc oxide (zinc yog txheej ntawm cov kav dej). Yog koj tau galvanized cov yeeb nkab kub heev, nws tuaj yeem tso tawm qee cov pa phem uas tuaj yeem ua rau koj mob zoo nkauj hauv cov koob tshuaj txaus, thiab yam tsawg kawg yuav ua rau koj lub caj pas thiab lub ntsws.
Ib tug kuj yuav nug, yuav ua li cas yog tias koj ua pa hauv galvanized hlau? Thaum twg vuam galvanized hlau, yuav tsum muaj lub tshuab ua pa kom cov zinc oxide pa taws los ntawm galvanizing tsis nqus tau. Inhalation ntawm zinc oxide fumes ua tau ua rau hlau ua npaws. Qhov mob hnyav dhau mus rau zinc oxide los ntawm kev ua pa ua rau mob khaub thuas zoo li cov tsos mob uas ua tau mob hnyav.
Hauv qhov no, hlau fume kub taub hau tuaj yeem tua koj?
Qhov teeb meem tiag nrog hlau fume fever yog ntev raug. Muaj tsawg tus kws kho hniav tau tuag thawj zaug lawv mob. Txawm li cas los xij, tom qab ob peb xyoos, kev puas tsuaj pib ntxiv. Ib txoj hauv kev zoo tshaj los tiv thaiv koj tus kheej yog khaws cov no pa taws los ntawm puas tau ncav cuag koj lub ntsws.
Puas yog welding galvanized steel toxic?
Vuam galvanized hlau paub tias ua rau hlau fume fever/galvanize lom. Thaum cov welder tau dhau los ntawm zinc oxide, galvanized lom yuav nto. Qhov kub heev los ntawm welding galvanized hlau tuaj yeem tsim zinc oxide.

Qhov kub ntawm qhov hluav taws kub kub li cas?
Feem ntau hom ntoo yuav pib combusting ntawm li 300 degrees Celsius. Cov pa roj hlawv thiab nce qhov kub ntawm cov ntoo mus txog 600 degrees Celsius (1,112 degrees Fahrenheit). Thaum cov ntoo tso tawm tag nrho nws cov gases, nws tawm charcoal thiab tshauv
Cov hlau nplaum puas yuav lo rau galvanized hlau?
"Galvanized" tsuas yog txhais tau hais tias muaj cov zinc txheej sab nraud ntawm cov Hlau. Yog hais tias cov hlau ismagnetic pib nrog, ces nws tseem yuav sib nqus tom qab galvanizing. Txij li feem ntau tsis muaj laj thawj rau galvanizestainless hlau, cov lus teb yuav luag ib txwm "yog, galvanized steel yog sib nqus"
Cov qauv dab tsi thaum koj nchuav hlau filings nyob ib ncig ntawm cov hlau nplaum?
Thaum cov ntaub ntawv hlau tau nchuav ib ncig ntawm cov hlau nplaum, cov duab ntawm cov hlau nplaum raug ntes. Vim li cas qhov no tshwm sim? Tsis tas li ntawd, cov ntaub ntawv hlau no cais ua cov qauv pom tseeb ntawm cov kab
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Thaum tshav kub kub muaj peev xwm vs tshwj xeeb tshav kub yog dab tsi?
Molar Thaum tshav kub kub muaj peev xwm yog ib qho kev ntsuas ntawm cov cua sov uas tsim nyog los nce qhov kub ntawm ib mole ntawm ib tug ntshiab tshuaj los ntawm ib tug degree K. Tshwj xeeb kub muaj peev xwm yog ib qho kev ntsuas ntawm tus nqi ntawm cov cua sov tsim nyog los nce qhov kub ntawm ib gram ntawm ib tug ntshiab. khoom los ntawm ib degree K
