nyom,
lub neej qub tshaj plaws
cov ntaub ntawv ntim khoom thiab cov khoom siv kho kom zoo nkauj,
Nws tau muaj nyob hauv ntiaj teb rau ntau txhiab xyoo.
Thaum ntxov li 3700 BC,
ancient Egyptians ua iav ornaments
thiab iav iav yooj yim.
niaj hnub Society,
iav txuas ntxiv txhawb kev nce qib ntawm tib neeg lub neej,
Los ntawm telescope ntawm tib neeg kev tshawb nrhiav qhov chaw
Optical iav lens siv
rau fiber optic iav siv nyob rau hauv cov ntaub ntawv kis tau tus mob,
thiab lub teeb teeb tau tsim los ntawm Edison
Nqa cov iav qhov kaj,
Txhua yam qhia txog lub luag haujlwm tseem ceeb ntawm cov khoom siv iav.
Nyob rau hauv lub neej niaj hnub no,
iav yog kev koom ua ke
txhua yam ntawm peb lub neej.
Hauv kev noj zaub mov noj txhua hnub,
Cov khoom siv iav coj practicality,
Tib lub sijhawm, nws ntxiv kev zoo nkauj thiab kev xav rau peb lub neej.
Hauv kev lag luam khoom siv hluav taws xob,
mobile xov tooj, computers,
LCD TV, LED teeb pom kev zoo thiab lwm yam khoom siv hluav taws xob
Tsis xav tau cov khoom zoo heev ntawm cov ntaub ntawv iav.
Hauv kev lag luam ntim tshuaj,
Cov iav yog ze rau peb txoj kev noj qab haus huv.
Hauv kev txhim kho lub zog tshiab,
Nws yog inseparable los ntawm kev pab ntawm iav ntaub ntawv.
Photovoltaic iav los ntawm photovoltaics
los tsim lub zog-npaum iav
Raws li lub tsheb tso saib iav thiab automotive iav,
Cov ntaub ntawv iav hauv ntau subdivisions
muaj lub luag haujlwm irreplaceable.
Thaum siv ntau tshaj 4,000 xyoo,
iav thiab Human Society
Harmonious coexistence thiab kev sib nrig sib txhawb,
ua kom dav pom los ntawm pej xeem
Ntsuab, environmentally friendly thiab recyclable
environmentally friendly cov ntaub ntawv,
yuav luag tib neeg
Txhua qhov kev txhim kho thiab kev vam meej,
Muaj cov khoom siv iav.
Cov khoom siv raw ntawm iav yog ntsuab
Ntawm cov silicate tebchaw uas yog lub ntsiab qauv ntawm iav, silicon yog ib qho ntawm cov ntsiab lus tshaj plaws nyob rau hauv lub ntiaj teb crust, thiab silicon muaj nyob rau hauv daim ntawv ntawm cov minerals nyob rau hauv cov xwm.
Cov khoom siv raw siv hauv iav feem ntau yog quartz xuab zeb, borax, dej qab zib tshauv, limestone, thiab lwm yam. Raws li kev xav tau ntawm iav sib txawv, ib qho me me ntawm lwm cov khoom siv raw tuaj yeem muab ntxiv los kho cov iav kev ua tau zoo.
Cov khoom siv raw no tsis muaj teeb meem rau ib puag ncig thaum tiv thaiv kev tiv thaiv thaum siv.
Tsis tas li ntawd, nrog kev txhim kho ntawm iav technology, kev xaiv cov khoom siv raw tau dhau los ua cov khoom siv tsis muaj tshuaj lom neeg uas tsis muaj kev phom sij rau tib neeg lub cev thiab ib puag ncig, thiab muaj kev tiv thaiv kev nyab xeeb hauv cov txheej txheem siv los xyuas kom meej qhov ntsuab thiab noj qab nyob zoo. xwm ntawm iav raw khoom.
Cov txheej txheem ntau lawm ntawm iav feem ntau muaj plaub kauj ruam: batching, melting, sib sau thiab annealing, thiab ua.Tag nrho cov txheej txheem ntau lawm tau pib ua tiav kev tsim khoom ntse thiab tswj.
Tus neeg teb xov tooj tuaj yeem teeb tsa thiab kho cov txheej txheem cov txheej txheem tsuas yog hauv chav tswj hwm, thiab siv lub hauv paus kev saib xyuas ntawm tag nrho cov txheej txheem tsim khoom, uas txo cov kev siv zog ua haujlwm thiab txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm.
Thaum lub sij hawm tsim cov iav, ib tug xov tooj ntawm zoo thiab emission soj ntsuam cov ntsiab lus tau tsim los saib xyuas cov pa roj emissions thaum lub sij hawm tsim thiab nruj me ntsis xyuas kom meej tias iav ntau lawm raws li lub teb chaws ib puag ncig tiv thaiv qauv.
Tam sim no, nyob rau hauv cov txheej txheem ntawm cov iav ntau lawm, lub ntsiab qhov chaw ntawm tshav kub nyob rau hauv lub iav melting txheej txheem yog huv si zog, uas muaj zog tawm tswv yim los ntawm lub teb chaws xws li natural gas roj thiab hluav taws xob.
Nrog rau txoj kev loj hlob thiab kev vam meej ntawm iav ntau lawm technology, daim ntawv thov ntawm oxyfuel combustion technology thiab hluav taws xob melting technology nyob rau hauv iav ntau lawm zoo heev thermal efficiency, txo zog noj thiab txuag zog.
Txij li thaum cov txheej txheem combustion siv oxygen nrog ib tug purity ntawm 95%, cov ntsiab lus ntawm nitrogen oxides nyob rau hauv cov khoom combustion yog txo, thiab cov cua kub ntawm high-temperature flue gas generated los ntawm combustion kuj zoo tu qab tso rau cua sov thiab lub zog tsim.
Nyob rau tib lub sijhawm, txhawm rau txhawm rau txo cov pa phem kom zoo dua qub, lub Hoobkas iav tau ua tiav desulfurization, denitrification thiab kev tshem tawm plua plav tawm ntawm cov roj flue kom txo qis emissions.
Cov dej hauv kev lag luam iav feem ntau yog siv los ua kom txias, uas tuaj yeem paub txog kev siv dej.Vim tias cov iav tsis ruaj khov, nws yuav tsis ua rau cov dej txias, thiab lub Hoobkas iav muaj kev ywj pheej ncig, yog li tag nrho cov txheej txheem tsim khoom yuav tsis tsim cov dej khib nyiab.
