Tooj liab, cov hlau qub qub, tau ua si tsim kho kom zoo nkauj, kev tsim kho vaj tse qub, kev ua yeeb yam, thiab lwm daim teb ntawm tib neeg kev vam meej.
Nrog kev nce qib ntawm thev naus laus zis thiab kev txhim kho ntawm tib neeg, cov tib neeg tsis tsuas yog kawm kom txhim kho tooj liab tab sis kuj kawm txhim kho nws cov khoom los ntawm kev ua haujlwm. Tooj dag yog ib qho ntawm cov zoo tshaj plaws - paub cov roj cop coper tooj liab.
Niaj hnub no, cia peb tham txog qhov sib txawv ntawm brass thiab tooj liab thiab lawv cov ntawv thov!
Dab tsi yog ntshiab tooj liab? Tooj liab, kuj feem ntau hu ua liab tooj liab, feem ntau muaj dua 99% tooj liab. Txawm li cas los Purer tooj liab, xws li tooj pob hluav taws xob lossis cov oxygen {{2} Tus tooj dawb dawb, muaj cov ntsiab lus tooj dawb ntawm ntau tshaj 99.9%.
Ntsiav tooj liab muaj hluav taws xob dawb huv thiab thermal ua haujlwm thiab tau siv dav ua cov khoom siv tseem ceeb thiab cov xaim hluav taws xob. Nws zoo heev ductility thiab kev ua haujlwm ua rau nws xaiv qhov zoo tshaj plaws rau kev tsim ntau yam precision seem.
Ntsiav ntshiab kuj muaj cov khoom lag luam corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv cov khoom lag luam dej nag thiab cov khoom siv marrium. Hauv kev tsim txuj ci tsim, tooj liab tuaj yeem raug muab tso rau hauv cov duab puab zoo lossis cov duab loj xws li bells thiab tripods, saib xyuas tus nqi zoo nkauj.
Dab tsi yog tooj dag? Tooj dag yog binary alloy muaj li luam tawm ntawm tooj liab thiab zinc. Nyob ntawm cov ntsiab lus zinc, tooj dag tuaj yeem faib ua cov brasses (xws li BRASS (xws li BRASSES (xws li kev coj ua tooj daj thiab txhuas tooj).
Feem ntau hais lus, raws li cov cov ntsiab lus zinc ntau ntxiv, cov xim ntawm brass me ntsis ua ntais thiab nws cov plastent nce ntxiv, tab sis nws cov platity txo kom tau. Piv rau cov tooj liab ntshiab, tooj dag muaj peev xwm ntau dua thiab hnav tsis kam, ua rau nws dav siv hauv kev lag luam machinery tsim. Piv txwv li, tooj dag zog, bearings, thiab lwm cov khoom siv tuaj yeem tiv thaiv siab yam tsis muaj kev hnav lossis hnav.
Tsis tas li ntawd, vim tias brass yooj yim ua rau cov yeeb yaj kiab oxide pleev rau nws sab, nws txhim kho corrosion tsis kam, tshwj xeeb tshaj yog nyob hauv huab cua. Yog li ntawd, nws yog dav siv nyob rau hauv cov khoom zoo nkauj, cov twj paj nruas twj paj nruag, thiab lwm yam kev siv.
Tom ntej no, cia peb tham txog kev sib piv ua tau zoo thiab cov chaw thov ntawm cov tooj liab thiab tooj dag!
Hais txog cov khoom siv lub cev, tooj liab muaj hluav taws xob siab dua thiab thermal conductivity, thaum tooj dag cov khoom siv zog thiab hnav tsis kam.
Nyob rau hauv cov nqe lus ntawm cov tshuaj ruaj khov, thaum ob qho tib si yog cov kev daws teeb meem zoo nkauj, xws li cov dej hiav txwv (xws li cov nqaij qaib), thaum tus tooj liab zoo nkauj yog qhov ruaj khov. Raws li rau tus nqi, tooj dag feem ntau raug nqi tsawg dua li cov tooj liab ntshiab vim nws suav nrog qee qhov kev faib tawm zinc.
Nyob rau hauv lub teb ntawm lub zog sib kis, ntshiab tooj tooj liab yog ib qho ntawm cov siv feem ntau siv hauv cov hluav taws xob kis tau cov kab vim nws txoj kev ua hluav taws xob zoo. Los ntawm cov xov hlau tshaj plaws rau siab - voltage kis rau cov hluav taws xob hluav taws xob me me hauv tsev, nws yog yuav luag txhua lub sijhawm los ntawm tooj liab.
Nyob rau hauv cov kws kos duab kho kom zoo nkauj, tooj dag, nrog nws cov kev ua tiav golden thiab yooj yim nws qhov chaw muaj qhov chaw ua kom zoo nkauj sab hauv thiab sab nraud. Qhov rooj tuam tsev, cov khau khiab, teeb, thiab lwm yam khoom zoo nkauj yog feem ntau ua los ntawm tooj dag, uas yog ob qho tib si ua kom zoo nkauj thiab ruaj khov.
Hauv kev tsim tawm kho tshuab, tooj dag yog qhov kev xaiv zoo rau kev xaiv zoo rau cov khoom siv siab thiab zoo machinity. Tooj dag feem ntau siv nyob rau hauv cov ntsiab lus tseem ceeb, xws li piston pins, txuas cov rod bushings, thiab valve lub cev nyob rau hauv cov tshuab hydraulic.
Nyob rau hauv cov cuab yeej ua suab paj nruas, tooj dag yog thawj cov khoom siv rau ntau cov twj paj nruag cua hauv Orchestras, xws li cheatrets thiab trumpones. Cov cuab yeej siv kiv tes no 'cov cim tshwj xeeb thiab kev ua kom zoo nkauj rau imbue nkauj nrog kev xav nplua nuj.
Hauv kev ua haujlwm txhua hnub tsim, ntau yam khoom xws li cov kais dej, xauv, thiab zippers yog ua los ntawm tooj dag, tiv nqi rau nws lub ntsej muag zoo nkauj thiab lub neej ntev.
Hauv cov ntsiab lus, ntshiab tooj liab thiab tooj dag txhua tus muaj lawv tus kheej lub zog, ua kom muaj qhov zoo dua hauv cov ntawv thov sib txawv.
Nrog kev nce qib sai ntawm cov ntaub ntawv tshiab, peb ntseeg tias cov khoom no yuav pom lawv qhov chaw ntxiv los ntawm kev nce qib kev nce qib thiab kev nce qib kev nce qib thiab kev txhim kho kev nce qib thiab kev txhim kho. Seb rau hauv kev tsim khoom lag luam ib txwm muaj los yog cov qauv kos duab niaj hnub thiab tooj liab tseem yuav txuas ntxiv nrog lawv cov duab tshwj xeeb, sau cov tshooj tshiab rau lawv tus kheej ...
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.
