Hauv tus txheej txheem GB/Tll76-1987. Muaj 3-8-6-1 cam khwb cia tin bronze, 3-11-4 cam khwb cia tin bronze, 5-5-5 cam khwb cia tin bronze, 10-1 cam khwb cia tin bronze, 10-5 cam khwb cia tin bronze, 10 -2 cam khwb cia tin bronze, thiab lwm yam.
Tin tooj liab yog cov hlau tsis muaj hlau uas tsis tshua muaj qhov nqaim nqaim, uas tuaj yeem siv los tsim cov castings nrog cov duab nyuaj, tshem tawm qhov nkhaus thiab tsis xav tau huab cua nruj. Lub tes tsho tooj liab tooj liab tooj liab yog tiv taus xeb nyob rau hauv huab cua, dej hiav txwv, dej tshiab thiab ua pa, thiab tau siv dav hauv chav rhaub dej kub thiab nkoj mus rau qhov chaw.
Changzhou Pufa feem ntau tsim 5-5-5, 10-1, 10-5 cam khwb cia tooj liab tooj liab, thiab nws cov khoom suav nrog tes tsho tooj liab, tooj liab tooj liab, tooj liab swb, thiab tooj liab cab log. Hauv qhov kev thov tiag tiag ntawm cov tooj liab tooj liab tooj liab lub tes tsho, ntxiv rau tin, nws kuj tseem muaj cov pab txhawb lub zog xws li zinc, txhuas, phosphorus lossis nickel, yog li qhov cuam tshuam ntawm lawv thiab cov khoom tsis huv tsis tuaj yeem tsis quav ntsej.
Lub luag haujlwm ntawm zinc. Ntxiv qhov tsim nyog ntawm zinc rau Cu-Sn binary alloy tuaj yeem txo qhov kub nruab nrab ntawm cov hlau, txhim kho qhov ua tau zoo ntawm cov hlau, txo cov phab ntsa tuab cuam tshuam ntawm tin tooj liab castings, thiab txhim kho dej siab tsis kam ntawm cov castings . Castings uas yuav tsum tau tiv taus cov dej siab yog qhov tsim nyog. Qhov ntxiv ntawm Zn yuav txo qis kev txhim kho corrosion ntawm tin tooj liab. Yog li ntawd, txhawm rau ua kom tau raws li qhov xav tau ntawm kev sib txawv ntawm kev txhim kho corrosion thiab kev sib cog ua ke, nrum tin tooj liab nrog sib txawv tin-zinc piv tuaj yeem siv tau.
Lub luag haujlwm ntawm txhuas. Tom qab ntxiv cov hmoov txhuas rau hauv cov tin, cov dej tsis kam ntawm cov casting tuaj yeem txhim kho. Tsis tas li ntawd, cov hlau lead hauv cov tooj liab sib xyaw ua ke raws li cov ntsiab lus me me kuj tseem tuaj yeem ua qhov zoo rau tus kheej lub cev thaum lub sijhawm txheej txheem zawv zawg thiab txo cov hlau phom.
Lub luag haujlwm ntawm phosphorus. Phosphorus muaj kev cuam tshuam zoo rau cov qauv thiab cov yam ntxwv ntawm cov hlau. Phosphorus nthuav tawm qhov kub thiab txias ntau yam ntawm tin tooj liab, yog li qhov nyiam ua rau kev sib cais yog ntau dua li ntawm tin bronze tsis muaj phosphorus. Phosphorus muaj qhov zoo sib xws rau cov pa oxygen, thiab txo ntau cov oxides hauv cov hlau ua kua los ntxuav cov hlau phom, yog li txhim kho qhov ua tau zoo ntawm cov hlau.
Lub luag haujlwm ntawm npib tsib xee. Ntxiv npib tsib xee rau Cu-Sn binary alloy tuaj yeem ua kom zoo dua cov pob zeb siv lead ua, nce lub zog ntawm cov hlau, txo cov hlau sib xyaw ua kom sov lub sijhawm sib txawv, txhim kho kev sib dhos ntawm kev nrum, thiab txhim kho cov hlau nplaum' muaj peev xwm tiv taus dej hiav txwv corrosion.
