Cov tooj daj yog qhov nyuaj, yooj yim yaj, tuaj yeem pov tau zoo, thiab ruaj khov rau hauv huab cua, yog li txawm tias Cov Hlau Hlau Tom qab Lub Hnub Nyoog Bronze, nws tsis poob nws siv cov nqi. Ntxiv rau cov tin bronze daim hlau uas muaj 3% txog 14% tin, phosphorus, zinc, txhuas thiab lwm yam ntsiab lus tau txuas ntxiv. Nws yog ib qho alloy uas tau siv thaum ntxov los ntawm noob neej, thiab nws tau siv ntev txog 4,000 xyoo. Nws yog corrosion-resistant, hnav-resistant, muaj cov yam ntxwv zoo thiab cov txheej txheem kev ua tau zoo, thiab tuaj yeem ua rau welded thiab brazed zoo yam tsis muaj lub txim thaum lub sij hawm cuam tshuam.
Nws tau faib ua tiav tin bronze thiab cam khwb cia tin tooj dag. Cov ntsiab lus ntsiab lus ntawm tin bronze rau kev ua kom siab yog tsawg dua 6% mus rau 7%, thiab cov ntsiab lus ntawm cov ntsiab lus ntawm cov tin bronze yog 10% txog 14%. Cov qib kawm uas nquag siv yog QSn4-3, QSn4.4-2.5, QSn7-O.2, ZQSn10, ZQSn5-2-5, ZQSN6-6-3, thiab lwm yam Tin bronze yog hlau tsis muaj hlau tsis muaj hlau tsis muaj hlau tsis muaj pob zeb me me tus nqi. Nws tuaj yeem siv los tsim cov hlau cam nrog cov qauv duab tsis yooj yim, cov phiaj xwm meej thiab cov huab cua nruj yuav tsum tau.
Tin bronze daim hlau muaj peev xwm tiv taus corrosion hauv cov huab cua, dej hiav txwv, dej tshiab thiab chav, thiab siv dav hauv chav rwj thiab nkoj qhov chaw nkoj. Phosphorus-uas muaj cov tin bronze muaj cov yam ntxwv zoo thiab siv tau los ua cov khoom coj los tiv thaiv thiab ywj qhov muag ntawm cov cuab yeej siv hauv tshuab siab. Cov hmoov txhuas uas muaj tooj daj txhuas tau siv ua cov khoom coj los tiv thaiv thiab cov kabmob swb, thiab zinc-muaj cov tin bronze tuaj yeem siv ua cov suab nrov zoo.
Lub solidification ntau ntawm tin bronze phaj yog loj, dendrite cais yog loj heev; concentrated shrinkage tsis yooj yim rau hauv daim ntawv thaum lub sijhawm solidification, thiab lub ntim shrinkage yog me me; tin rov cais sib cais tau yooj yim tshwm sim hauv lub ingot, thiab cov pob dawb tuaj yeem pom ntawm cov nplaim thaum nws mob hnyav, thiab txawm tias cov nplua nuj tin feem ntau, feem ntau hu ua tin hws, txhim kho casting txoj kev thiab cov txheej txheem kev tuaj yeem txo qhov ntsuas ntawm kev rov ua segregation; hauv cov kua pleev ua kua, tin yog nquag nquag tsim nyuaj thiab thim kev koom ua ke SnO2, thiab smelting yuav tsum tau muaj deoxidized tag nrho kom tiv thaiv kev txo qis ntawm cov neeg kho tshuab alloy uas muaj los ntawm kev koom ua ke.
Nws muaj kev cuam tshuam me me mus rau kev ua kom kub thiab roj, thiab tuaj yeem tsim ua welded thiab brazed zoo; tsis muaj qhov tawg thaum cuam tshuam, nws tsis-sib nqus, txias-tiv taus, thiab muaj hnav zoo heev. Tin bronze phaj yog ib qho tseem ceeb tooj liab alloy siv nyob rau hauv kev lag luam. Txhawm rau txhawm rau txhim kho nws cov casting, tshuab thiab coj tsis kam cov khoom, thiab txuag tin, alloy ntsiab xws li phosphorus, zinc, txhuas, thiab lwm yam yog ntxiv rau tin bronze. Yog li ntawd, tin bronze yuav muab faib ua peb hom: tin-phosphorus bronze, tin-zinc bronze thiab tin-zinc-lead.
