Ua ntej, dab tsi yog cov hlau - tooj dawb tooj?
Lead - Tus tooj liab dawb yog hais txog alloys lossis cov ntsiab lus tooj liab uas nws cov ntsiab lus ua tau raws li cov qauv kev nyab xeeb.
Lead - dawb tooj dawb tsis yog tib yam li tooj liab liab. Tooj liab yog kev ua haujlwm ntshiab ntshiab, nrog rau cov ntsiab lus tooj liab ntawm 99.5% {4} {{{{6} rh {liab tsos. Lead {{{}} dawb tooj liab tuaj yeem yog cov khoom siv txhuas uas tau muab los ntawm cov ntsiab lus tooj liab xws li brass kev kho mob tshwj xeeb kom ua tiav lead {9} cov qauv dawb. Txawm li cas los xij, txhuas tooj liab txawv los ntawm liab tooj liab hauv kev sib xyaw, cov yam ntxwv, thiab siv.
Cov ntsiab lus coj ua rau cov ua lei- dawb tooj liab sib txawv raws li daim ntawv thov thiab qauv. Piv txwv li, hauv qee cov khoom siv hluav taws xob thiab cov qauv tsheb yuav tsum muaj cov ntsiab lus txhuas tsawg dua li 0.1% (nrog rau cov ntsiab lus txhuas tsawg dua 4%).
Kev lag luam hluav taws xob Asmeskas yuav tsum muaj cov ntsiab lus txhuas tsawg dua 0.01%.
Cov yam ntxwv tseem ceeb ntawm cov thawj coj - dawb tooj dawb yog cov haujlwm zoo, muaj zog thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab kev nyab xeeb thiab ib puag ncig kev tiv thaiv thiab ib puag ncig.
Yog li, ua li cas yog le ca - h} dawb tooj liab tsim?
Kauj ruam 1: Xaiv cov khoom xaiv. Xaiv cov ntaub ntawv raw raug tsim nyog, xws li high- tooj liab, thiab lwm yam kev sib xyaw ua ke, thiab lwm yam kev sib ntxiv ntxiv rau cov hmoov txhuas {3} tooj dawb tooj liab).
Kauj ruam 2: SMELTING. Cov tooj liab electrolytic yog rhuab mus rau qhov kub siab (feem ntau 1100-1200 degree) kom yaj nws mus rau hauv lub xeev ua kua.
Kauj ruam 3: Ntxiv cov ntsiab lus. Zinc thiab lwm yam ua rau {{2} Cov tooj liab hloov pauv tau ntxiv rau Molten Tooj piv thiab do kom huv si kom ntseeg tau tias muaj kev sib xyaw ua ke.
Kauj Ruam 4: Kho Kom Zoo Dua. Refining cov neeg sawv cev tau ntxiv rau tshem tawm impurities thiab roj av, txhim kho lub purity thiab zoo ntawm lub tooj liab alloy. Refining cov neeg sawv cev feem ntau suav nrog fluorite, coldolite, borax, sidar oxide, thiab titanium dioxide.
KAUJ RUAM 5: CRETING. Lub npe ua kom tus tooj liab hlau alloy tau nrum ntawm qhov ntsuas kub uas tsim nyog (piv txwv li} Thaum kawg, kev ua tom ntej siv qhov chaw. Nyob ntawm cov khoom yuav tsum tau ua, cov kev ingots raug zam txim, extrusion, yob, thiab ncab cov pas nrig, cov kab, thiab xaim.
Yog li, dab tsi yog cov ntawv thov tseem ceeb rau cov hmoov txhuas - tooj dawb tooj?
Cov Khoom Siv Hluav Taws Xob thiab hluav taws xob: Nws yog dav siv nyob rau hauv kev tsim cov khoom siv hluav taws xob thiab siv hluav taws xob, thiab lwm yam kev lag luam pub dawb thiab muaj kev coj ua thiab muaj hluav taws xob zoo thiab muaj hluav taws xob tau zoo.
Chav dej kho tau zoo: nws yog siv rau hauv cov kais dej, li qub, thiab chav dej ua kom cov chaw da dej corrosion thiab kev nyab xeeb ntawm chav dej.
Cov cuab yeej siv kho mob: nws tuaj yeem siv los tsim cov cuab yeej kev kho mob, xws li kev phais cov cuab yeej siv, cov cuab yeej hniav, thiab cov cuab yeej kho mob. Nws txoj kev nyab xeeb thiab biocompatibility yog qhov tseem ceeb rau kev siv tshuaj kho mob.
Cov neeg kho tshuab tsim: hauv kev siv tshuab engineering, Lead - Tus tooj dawb yog siv los tsim cov khoom siv dawb, thiab cov ntsia hlau, thiab lub zog, thiab zog.
Lub tuam txhab muaj pawg ntawm cov coj tooj liab ua ntau lawm cov kab hauv Suav teb, suav nrog:
German tau yog precision tooj liab raj ntau lawm kab (ib xyoos tawm ntawm 30,000 tons)
Japanese technology Tooj liab ntawv tuav kab (thinnest txog li 6μm)
Tsis Siv Neeg Siab Tooj Liab Bar Nruam Extrusion Kab
Cov Ntawv Ntse Copper thiab Sawb Fining Mill Chav Tsev
Digitalized kev tswj hwm thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm tau pom los ntawm cov khoom siv ntawm cov khoom lag luam, thiab qhov tseeb ntawm cov khoom tuaj yeem ncav cuag ± 0.01 hli.
