C2680 Brass Tube, Nta
C2680 Brass Tube, Lub teeb yuag, zoo thermal conductivity, siab kub tsis muaj zog.Nws feem ntau yog siv los tsim cov khoom siv hluav taws xob hloov hluav taws xob (xws li condenser, thiab lwm yam).Nws kuj yog siv rau kev sib sau cov kav dej kub qis hauv cov khoom siv oxygen.Cov kav dej me me feem ntau yog siv rau kev xa cov kua siab (xws li lub tshuab lubrication, roj siab system, thiab lwm yam) thiab siv los ua cov twj ntsuas siab, thiab lwm yam. Cov raj tooj dag muaj zog thiab tiv taus corrosion.
Feem ntau muaj cov txiaj ntsig zoo hauv qab no: tooj liab raj tawv tawv, tsis yooj yim rau corrosion, thiab kub tsis kam, siab tsis kam, tuaj yeem siv ntau yam tsis yog tooj liab ib puag ncig.Thiab piv nrog tooj dag raj, qhov tsis txaus ntawm ntau lwm cov khoom siv yeeb nkab yog pom tseeb, piv txwv li yav dhau los qhov chaw nyob siv ntau galvanized steel raj, nws xeb yog yooj yim heev, siv sij hawm tsis ntev tuaj yeem tshwm kais dej cov plaub hau daj, tam sim no decrescent. tos qhov teeb meem.Kuj tseem muaj qee cov ntaub ntawv nyob rau hauv qhov kub thiab txias lub zog yuav txo tau sai, thaum siv rau cov kav dej kub yuav ua rau muaj kev phom sij tsis zoo.Tab sis vim tooj liab muaj qhov melting point ntawm 1,083 degrees, qhov kub ntawm cov dej kub muaj qhov cuam tshuam me ntsis rau cov raj tooj dag.Common tooj dag raj muaj xws li hluav taws xob tooj dag raj, tub yees tooj dag tube, siab siab tooj dag raj, corrosion resistant brass tube, kev twb kev txuas tooj dag raj, waterway brass tube, hluav taws xob cua sov tooj dag raj thiab muaj tooj dag raj.
Keeb kwm kev loj hlob
Txog tam sim no, cov khoom siv tooj liab ntxov tshaj plaws nyob hauv lub ntiaj teb no feem ntau yog nyob rau sab hnub poob Asia, xws li Iraq's Zawei Chemi cheeb tsam, pom tooj liab dai kom zoo nkauj, muaj hnub nyoog li ntawm 10,000 BC txog 9,000 BC;Copper ornaments kuj tau pom nyob rau hauv ali Kashi nyob rau sab hnub poob Iran, yos los ntawm 9,000 txog 7,000 BC;Cov koob tooj liab thiab cov cones tau pom nyob rau ntawm qhov chaw ntawm Chayoni nyob rau yav qab teb Qaib ntxhw, yos los ntawm ib ncig ntawm 8,000 BC.Cov khoom siv tooj liab no yog cov khoom siv tooj liab liab, tsis yog los ntawm smelting ore tooj liab.
Los ntawm kev siv cov tooj liab ntshiab, rau smelting tooj liab ore mus rau tooj liab ntshiab, rau smelting bronze alloy, noob neej tau ntsib lub sij hawm ntev ntawm kev tshawb nrhiav, zoo li lub ntiaj teb khawv koob ntawm tooj liab los tsim ib lub sijhawm glittering qhov me ntsis.
Qhov ntxov tshaj plaws tooj liab smelting nyob rau hauv lub ntiaj teb no tau pom nyob rau hauv Shaanxi, Tuam Tshoj.Xyoo 1973, ib lub phaj tooj dag semicircular thiab lub raj tooj dag tau pom nyob rau hauv Jiangzhai Cultural site nyob rau hauv Lintong, Shaanxi xeev, yos mus txog 4700 BC.Tsim nyog taw qhia tias lub teeb pom kev hauv Shanghai tsis ntev los no, siv X-ray fluorescence scanning tsom xam, pom tias zinc cov ntsiab lus nyob rau hauv ntau qhov chaw ntawm lub zos ntawm tooj dag hlais qhiav muaj qhov sib txawv tseem ceeb, thiab ua rau ib qho kev faib tawm, nws cov yam ntxwv thiab kev txo qis hauv lub xeev. txoj kev ntawm tooj dag yog tib yam, yog li ua pov thawj cov poj koob yawm txwv invented nyob rau hauv kev siv tej yam ntuj tso hlau thiab hlau casting yog siv thaum kub burnt los yog khoom txo smelting hlau.
C2680 Brass Tube, Kev faib tawm tseem ceeb
Lead tooj dag
Lead yog insoluble nyob rau hauv tooj dag thiab faib ntawm grain ciam teb raws li ib tug dawb particle.Lead tooj dag muaj α thiab (α + β) raws li nws cov qauv.Alpha txhuas tooj dag tuaj yeem tsuas yog txias deformed lossis kub extruded vim muaj kev phom sij loj ntawm cov hlau lead thiab tsis tshua muaj plasticity ntawm qhov kub thiab txias.(α + β) txhuas tooj dag muaj qhov zoo ductility ntawm qhov kub thiab txias tuaj yeem ua rau forged.
Tin tooj dag
Qhov sib ntxiv ntawm tin hauv tooj dag tuaj yeem pom tseeb txhim kho cov cua sov ntawm cov hlau, tshwj xeeb tshaj yog muaj peev xwm los txhim kho corrosion ntawm seawater, yog li tin tooj dag hu ua "navy brass".
Tin tuaj yeem yaj mus rau hauv tooj liab - raws li cov khoom siv los txhim kho cov tshuaj.Txawm li cas los xij, nrog kev nce ntawm cov ntsiab lus tin, yuav muaj nkig R theem (CuZnSn compound) hauv cov hlau, uas tsis tsim nyog rau cov yas deformation ntawm cov hlau, yog li cov ntsiab lus tin ntawm tooj dag feem ntau nyob rau hauv thaj tsam ntawm 0.5%. ~ 1.5%.
Feem ntau siv tin tooj dag hSN70-1, HSN62-1, HSN60-1 thiab lwm yam.Cov qub yog α alloy nrog cov yas siab thiab tuaj yeem ua tiav los ntawm kev txias thiab kub siab.Ob hom hlau tom kawg muaj (α + β) ob-theem qauv, thiab feem ntau me me ntawm R theem, chav tsev kub plasticity tsis siab, tuaj yeem tsuas yog deformed hauv lub xeev kub.
Manganese tooj dag
Manganese muaj ntau dua solubility hauv cov khoom tooj dag.Lub zog thiab corrosion tsis kam ntawm cov hlau tuaj yeem txhim kho tau zoo yam tsis muaj qhov txo qis los ntawm kev ntxiv 1% ~ 4% manganese rau hauv tooj dag.
Manganese tooj dag muaj (α + β) microstructure thiab hMN58-2 feem ntau siv.Nws muaj kev zoo siab machining kev ua tau zoo nyob rau hauv txias thiab kub xeev.
Hlau, tooj dag
Nyob rau hauv hlau tooj dag, hlau yog precipitated los ntawm hlau-nplua nuj hais raws li siv lead ua nuclei rau refine nplej thiab tiv thaiv recrystallization nplej los ntawm loj hlob tuaj, thiaj li los txhim kho cov neeg kho tshuab thiab technological zog ntawm lub alloy.Hlau tooj dag nyob rau hauv cov ntsiab lus hlau feem ntau yog tsawg dua 1.5%, nws cov qauv yog (α + β), muaj zog thiab tawv, plasticity zoo heev ntawm qhov kub thiab txias, lub xeev txias kuj tuaj yeem deformed.Cov khoom siv feem ntau yog HFE59-1-1.
Nickel nyiaj
Nickel thiab tooj liab tuaj yeem tsim cov kev daws teeb meem txuas ntxiv thiab ua kom loj dua α theem cheeb tsam.Kev tiv thaiv corrosion ntawm tooj dag hauv huab cua thiab dej hiav txwv tuaj yeem txhim kho los ntawm kev ntxiv npib tsib xee.Nickel kuj tseem tuaj yeem ua kom qhov kub thiab txias recrystallization ntawm tooj dag thiab txhawb kev tsim cov nplej zoo.
Hni65-5 npib tsib xee- tooj dag muaj ib-theem α qauv, uas muaj cov yas zoo ntawm chav tsev kub thiab tuaj yeem deformed ntawm lub xeev kub.Txawm li cas los xij, cov ntsiab lus ntawm cov hlau lead impurity yuav tsum nruj me ntsis tswj, los yog cov khoom kub ua hauj lwm ntawm cov hlau yuav raug deteriorated loj.
