Taw qhia
Tinplate yog ib daim ntawv nyias nyias coated nrog ib txheej nyias ntawm tin, muab kev tiv thaiv corrosion zoo heev, solderability, thiab zoo nkauj tsos. Nws yog siv dav hauv kev ntim khoom, tshwj xeeb tshaj yog rau cov khoom noj thiab dej haus, nrog rau ntau yam kev siv hauv kev lag luam. Kev nkag siab txog qib sib txawv ntawm cov tinplate yog qhov tseem ceeb rau cov tuam txhab thiab cov neeg siv kawg xaiv cov khoom tsim nyog rau lawv cov kev xav tau tshwj xeeb. Kab lus no delves rau hauv ntau qib ntawm tinplate, lawv cov khoom, kev siv, thiab cov qauv tswj lawv. Yog xav paub ntxiv txog cov qib tinplate tshwj xeeb xws li 735 Tinplate , peb tshawb nrhiav lawv cov yam ntxwv tshwj xeeb thiab kev siv hauv kev lag luam sib txawv.
Nkag siab Tinplate Qib
Cov qib Tinplate tau muab cais raws li ntau yam, suav nrog hom hlau, temper designation, txheej hnyav, thiab tiav. Cov kev faib tawm no yog tswj hwm los ntawm cov qauv thoob ntiaj teb xws li ASTM A623 thiab European Norms (EN). Cov qhab nia txiav txim siab lub tinplate cov khoom siv kho tshuab, nto tiav, thiab tsim nyog rau ntau yam txheej txheem.
Hom hlau
Cov hlau substrate siv hauv tinplate ntau lawm cuam tshuam rau nws cov yam ntxwv. Hom steel feem ntau muaj xws li:
- Ib Leeg Txo Cov Hlau: Txias txo mus rau qhov xav tau tuab thiab annealed. Nws paub txog nws lub zog thiab formability.
- Ob Chav Reduced Steel: Txias txo, annealed, thiab tom qab ntawd raug txo qis thib ob, txhim kho lub zog thiab txo qhov tuab.
Temper Designations
Temper designation qhia qhov hardness thiab yooj ntawm tinplate, tseem ceeb heev rau kev tsim thiab fabrication txheej txheem. Cov qib temper feem ntau yog:
- T-1 txog T-5: Ib qho txo qis tinplate, nrog T-1 yog qhov softest thiab T-5 qhov nyuaj tshaj.
- DR-7 rau DR-9: Ob chav txo cov tinplate, muab lub zog siab dua nrog txo qhov yooj yim.
Piv txwv li, T-2 temper feem ntau yog siv rau kev sib sib zog nqus daim ntaub ntawv vim nws cov ductility zoo heev, thaum T-5 yog haum rau cov ntaub ntawv tiaj tus uas yuav tsum tau muaj zog dua.
Txheej hnyav
Cov tin txheej hnyav yog ntsuas hauv phaus ib lub thawv (lbs / puag lub thawv) hauv Teb Chaws Asmeskas lossis grams ib square meter (g / m²) nyob rau lwm qhov. Common txheej luj muaj xws li:
- Lightly Coated (0.10 / 0.10 lb / puag lub thawv): Siv thaum muaj kev tiv thaiv corrosion tsawg heev.
- Standard Coated (0.25 / 0.25 lb / puag lub thawv): Haum rau kev siv dav dav.
- Hnyav Coated (1.00 / 1.00 lb / puag lub thawv): Muab qhov siab tshaj plaws corrosion tsis kam rau qhov chaw hnyav.
Kev xaiv ntawm txheej hnyav cuam tshuam rau lub txee lub neej thiab kev ua haujlwm ntawm cov khoom kawg, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive.
Nto tiav
Tinplates muaj nyob rau hauv ntau qhov chaw tiav, cuam tshuam rau cov tsos thiab lacquer adherence:
- Bright Finish: Muab lub ntsej muag ci ntsa iab, zoo tagnrho rau cov ntawv siv kho kom zoo nkauj.
- Pob zeb Finish: Ib qho dull tiav siv thaum cov khoom kho qhov muag tsis tseem ceeb.
- Matte Finish: Txhim kho lacquer adhesion thiab feem ntau siv rau hauv qhov kawg thiab hau.
Daim ntawv thov sib txawv Tinplate Qib
Cov qib sib txawv ntawm tinplate yog tsim rau cov ntawv thov tshwj xeeb thoob plaws kev lag luam. Nkag siab txog cov ntawv thov no pab xaiv cov khoom tsim nyog rau kev tsim khoom:
Khoom noj khoom haus thiab dej haus ntim
Tinplates nrog tus qauv txheej hnyav thiab softer tempers (T-2 rau T-3) yog nyiam rau cov kaus poom zaub mov, tso cai rau kev sib sib zog nqus nqus thiab embossing yuav tsum tau nyob rau hauv kev tsim khoom. Qhov zoo tshaj plaws corrosion kuj ua kom cov khoom muaj kev nyab xeeb thiab ua haujlwm ntev.
Hauv kev ntim dej haus, tinplates yuav tsum tiv taus lub siab sab hauv thiab tuav daim ntawv. Ob chav txo qis xws li DR-8 feem ntau yog siv rau lawv lub zog thiab cov ntsuas nyias, txo cov nqi khoom yam tsis muaj kev cuam tshuam kev ua haujlwm.
Aerosol Ntim
Kev tsim cov kaus poom aerosol yuav tsum tau tinplates nrog lub zog ntau dua los tiv thaiv kev kub ntxhov. Tempers zoo li T-5 thiab ob qib txo qis yog qhov zoo rau cov ntawv thov no. Lub tin txheej tiv thaiv corrosion los ntawm cov ntsiab lus tshuaj.
