Bronze yog tooj liab-ua raws tooj hlau. Nyob rau tib lub sijhawm, ntau yam hlau thiab lwm yam khoom siv tuaj yeem siv los ua kev ntxiv rau cov hlau no hauv cov nplaim hluav taws xob.
Bronze muaj pes tsawg leeg
Bronze yog lub npe dav dav rau ib pawg ntawm cov hlau hlau, cov yam ntxwv dav dav ntawm cov uas yog siv tooj liab ua lub hauv paus rau lawv cov khoom siv. Hauv txhua qhov tooj hlau tooj liab, tooj liab ua lub luag haujlwm tseem ceeb, vim nws txoj kev koom nrog hauv cov khoom tiav yog feem ntau tsawg kawg 70%. Txawm li cas los xij, vim muaj cov tshuaj ntxiv, tooj daj tau txais cov khoom ntxiv, piv txwv li, nws ua tsis zoo li tooj liab dawb huv. Tib lub sijhawm, tin tau muas thaum chiv thawj siv los ua cov khoom ntxiv, uas yog, cov khoom sib txuas ntxiv ntawm cov tooj hlau, uas, txawm li cas los xij, los txog niaj hnub no tseem siv cov khoom siv feem ntau hauv cov peev txheej no.
Cov kev siv ntau ntawm kev siv tooj yaj kab yog qhov tsim nyog tau los ntawm qhov tseeb hais tias hom hlau no tus yam ntxwv muaj qhov hnyav thiab muaj zog, tab sis tib lub sijhawm nws kuj tsis tshua yaj: nws cov ntsiab lus melting yog los ntawm 940 txog 1140 ° C. Tsis tas li ntawd, ib qho cuab yeej ntxiv ntawm tin tooj liab, uas tau tig mus ua qhov tsis tshua nyiam rau cov kev lag luam nws yog xim hlau, tau ua kom tsawg kawg ntawm nws qhov kev ua kom tau qis thaum lub sijhawm melting: nws tsuas yog li 1%, uas yog qhov qis dua hauv kev sib piv nrog tooj dag ua nrog kev siv lwm yam tshuaj ntxiv.
Daim ntawv qhia ua tooj ua xim bronze yog qhov hu ua tswb bronze, uas, raws li lub npe pom zoo, kuj tau siv los ua lub tswb nrov. Nws yog 80% ntshiab tooj liab thiab lwm 20% tin. Txawm li cas los xij, hauv qhov hais qhia tsis meej, qhov hloov pauv me me yog qhov tso cai, tus nqi uas yuav tsum tsis pub tshaj 3%.
Txawm li cas los xij, ntxiv rau tin, lwm yam hlau tam sim no tau siv los ua kev ntxiv rau tooj liab hauv kev ua tooj. Yog li, muaj cov tooj hlau alloys uas txhuas, hlau, npib tsib xee, silicon thiab lwm yam hlau yog siv rau alloying. Hauv qhov no, txawm li cas los xij, nws yuav tsum tau muab pov rau hauv lub siab tias tooj liab-zinc alloy tsis yog rau qeb ntawm tooj hlau tooj liab: muaj lub npe tshwj xeeb rau nws - tooj dag.
Daim ntawv thov ntawm tooj dag
Ib qho ntawm thawj qhov chaw nyob rau hauv uas tooj liab tau los ua ntau qhov tseem ceeb yog kev tsim khoom siv riam phom: thaum xub thawj nws tau siv, thiab lwm yam, rau kev tsim khoom tho thiab txiav riam phom, tab sis tom qab ntawd thaj tsam ntawm nws daim ntawv thov txav mus rau rab phom: piv txwv, txog rau thaum xyoo pua puv 19, nws tau ua cov khoom siv tseem ceeb rau kev tsim phom.
Tom qab, thaj tsam ntawm kev siv tooj daj los ua cov kab lis kev cai dhau los. Yog li, cov tooj xeb tooj liab tau dav siv rau kev tsim khoom siv tswb thiab lwm yam twj paj nruas. Tsis tas li ntawd, cov hniav nyiaj hniav kub, kho kom zoo nkauj sab hauv thiab cov khoom lag luam zoo sib xws tau tsim los ntawm nws. Niaj hnub no, tooj dag tsuas yog siv feem ntau hauv kev kho tshuab, qhov chaw nws pabcuam yog cov khoom siv rau kev tsim khoom ntawm qhov chaw uas muaj kev ntxhov siab ntau ntxiv thaum ua haujlwm.
