Taw qhia
Tinplate, ib daim ntawv nyias nyias coated nrog tin, yog cov khoom siv dav siv hauv ntim, tshwj xeeb tshaj yog rau cov khoom noj thiab dej haus. Ib qho tseem ceeb yam ntxwv ntawm tinplate yog nws temper, uas yog hais txog hardness thiab yooj ntawm cov hlau. Kev nkag siab txog kev npau taws hauv tinplate yog qhov tseem ceeb rau cov tuam ntxhab thiab cov neeg siv khoom kawg kom ntseeg tau tias cov khoom ua tau raws li qhov xav tau kev ua haujlwm. Lub temper cuam tshuam rau formability, lub zog, thiab haum ntawm tinplate rau ntau yam kev siv. Kab lus no delves rau hauv lub tswv yim ntawm kev npau taws hauv tinplate, nws qhov tseem ceeb, thiab nws cuam tshuam li cas ntawm cov khoom siv tinplate. Rau cov neeg txaus siab rau qhov tshwj xeeb ntawm cov khoom tinplate, cov ntaub ntawv ntau ntxiv tuaj yeem pom ntawm 7 42 typ.
Nkag siab Temper hauv Tinplate
Lub temper ntawm tinplate yog ib qho kev ntsuas ntawm nws hardness thiab nruj, uas yog txiav txim los ntawm cov hlau metallurgical zog thiab tus nqi ntawm txias txo thaum lub sij hawm ua. Tinplate temper yog cais siv cov qauv tsim uas qhia txog qib hardness, xws li los ntawm mos heev mus rau tawv heev. Cov kev faib tawm no yog qhov tseem ceeb vim tias lawv pab cov tuam txhab xaiv cov qib tinplate uas tsim nyog rau cov ntawv thov tshwj xeeb, kom ntseeg tau tias cov khoom tuaj yeem tiv taus cov txheej txheem tsim yam tsis muaj kev tawg lossis ua tsis tiav.
Classification ntawm Tinplate Tempers
Tinplate tempers yog tus qauv raws li kev cai thoob ntiaj teb xws li ASTM thiab ISO. Cov kev faib tawm feem ntau suav nrog T1, T2, T3, T4, T5, thiab DR (Double Reduced) qib. T1 sawv cev rau lub softest temper nrog lub siab tshaj plaws ductility, haum rau sib sib zog nqus daim ntaub ntawv. Raws li tus naj npawb temper nce, lub hardness thiab tensile zog nce, tab sis lub ductility txo. DR qib yog tsim los ntawm ob chav txias txo thiab muaj zog dua thiab hardness piv rau ib qho txo tinplate ntawm tib lub thickness.
Cov txheej txheem ntau lawm thiab nws cuam tshuam rau Temper
Kev tsim cov tinplate muaj ntau theem, suav nrog kub dov, txias dov, annealing, thiab tin txheej. Cov txheej txheem txias dov ua rau muaj kev kub ntxhov ntawm tinplate. Los ntawm kev tswj cov qib ntawm kev txo qis, cov tuam ntxhab tuaj yeem kho cov khoom siv ntawm cov hlau substrate. Annealing, txheej txheem kev kho cua sov, yog siv los kho cov ductility poob thaum lub caij txias dov. Txawm li cas los xij, nyob rau hauv kev tsim cov tempers nyuaj, annealing tej zaum yuav raug txwv los yog tshem tawm kom khaws cov qib uas xav tau hardness.
Ib Leeg Txo vs. Ob Chav Txo Tinplate
Ib leeg txo tinplate undergoes txias txo ua raws li annealing, uas ua rau ib tug tshuav nyiaj li cas ntawm lub zog thiab ductility haum rau cov kev siv. Ob chav txo tinplate, ntawm qhov tod tes, yog txias txo, annealed, thiab tom qab ntawd raug txo qis thib ob. Qhov kev txo qis ntxiv no ua rau cov hlau muaj zog thiab tawv tawv, ua rau DR tinplate zoo tagnrho rau cov ntawv thov uas xav tau cov ntsuas nyias nrog lub zog siab dua, xws li cov kaus poom aerosol thiab cov thawv ntim siab.
Daim ntawv thov sib txawv Tinplate Tempers
Xaiv qhov kev npau taws yog qhov tseem ceeb rau kev tsim khoom thiab kev ua haujlwm ntawm cov khoom kawg. Softer tempers (T1-T3) yog siv nyob rau hauv qhov chaw sib sib zog nqus nqus los yog complex forming yuav tsum tau, xws li nyob rau hauv ua cov kaus poom rau cov khoom noj xws li txiv hmab txiv ntoo thiab zaub. Nruab nrab tempers (T4) yog tsim rau cov kev siv dav dav uas yuav tsum muaj qhov sib npaug ntawm kev tsim thiab lub zog. Kev kub ntxhov siab (T5 thiab DR qib) yog siv rau cov khoom siv uas xav tau lub zog thiab nruj dua, xws li cov kaus poom dej haus, cov kaus poom pleev xim, thiab lub plhaub roj teeb.
Kev Kawm Txuj Ci: Kev Tsim Kho Dej Haus
Hauv cov dej haus tuaj yeem tsim khoom, kev siv cov tinplate nyuaj yog qhov tseem ceeb los xyuas kom meej tias cov kaus poom tuaj yeem tiv taus kev kub ntxhov sab hauv thiab sab nraud thaum tuav thiab kev thauj mus los. DR tinplate feem ntau yog ua haujlwm vim nws lub zog-rau-thickness piv piv, tso cai rau cov tuam txhab tsim cov kaus poom nyias, sib dua yam tsis muaj kev cuam tshuam kev ncaj ncees. Qhov no tsis tsuas yog txo cov nqi khoom siv xwb tab sis kuj txo qis ib puag ncig los ntawm kev txo cov hlau siv.
Kev Ntsuas thiab Kev Tswj Xyuas Zoo ntawm Tinplate Temper
Kev tswj xyuas zoo hauv tinplate ntau lawm suav nrog kev sim nruj kom ntseeg tau tias qhov kub siab ua tau raws li cov qauv teev tseg.
