Cov Kev Tsis Zoo Tseem Ceeb ntawm Galvanized Hardware
Kev Pheej Hmoo ntawm Hydrogen Embrittlement
Koj yuav tsum paub txogkev tawg ntawm hydrogenua ntej xaiv cov ntsia hlau thiab cov txiv ntoo galvanized. Qhov teeb meem no tshwm sim thaum hydrogen nkag mus rau hauv cov hlau thiab ua rau nws tawg. Cov hlau tawg tuaj yeem tawg lossis tawg thaum muaj kev ntxhov siab.
Muaj ntau yam ua rau muaj kev pheej hmoo ntawm hydrogen embrittlement:
- Kev xeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw acidic lossis ntsev, tsim cov hydrogen rau ntawm cov hlau.
- Cov dej noo ua lub luag haujlwm tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj av noo siab.
- Kev raug tshuaj lom thaum lub sijhawm tsim kho, zoo li ua haujlwm hauv cov huab cua ntub, tuaj yeem ua rau hydrogen nkag mus sai dua.
- Cov xwm txheej kev pabcuam uas tsis paub meej lossis cov av noo siab ua rau muaj kev pheej hmoo.
Koj kuj tseem yuav ntsib kev pheej hmoo ntau dua thaum peb yam no tshwm sim ua ke:
- Hydrogen muaj nyob.
- Tus fastener nyob rau hauv lub load tas li los yog kev ntxhov siab.
- Cov khoom siv yog yooj yim puas, tshwj xeeb tshaj yog cov hlau muaj zog heev.
Kev ntxhov siab uas tsis xav txog thaum lub sijhawm teeb tsa tuaj yeem ua rau cov ntsia hlau ntau dhau thiab ua rau muaj feem yuav tawg yooj yim dua. Koj yuav tsum tswj cov teeb meem kev ntxhov siab thiab tsis txhob siv cov khoom siv txuas nruj dhau.
Lub Tswv Yim:Yog tias koj siv cov khoom siv galvanized hauv cov chaw ntub dej lossis corrosive, xyuas seb puas muaj cov cim ntawm kev tawg lossis poob lub zog dhau sijhawm.
Cov Teeb Meem Txuas Los Ntawm Zinc Coating Thickness
Cov ntsia hlau thiab txiv ntoo uas raug galvanized muaj ib txheej zinc tuab. Cov txheej no tiv thaiv xeb, tab sis nws tuaj yeem ua teeb meem thaum koj sim khi cov khoom ua ke. Qhov tuab ntawm cov txheej zinc tuaj yeem ua rau cov ntsia hlau thiab txiv ntoo nyuaj rau haum rau hauv qhov lossis xov.
| Aspect | Kev Qhia Txog |
|---|---|
| Zinc Txheej ThicknessNtau yam | 45–65 μm |
| Kev Cuam Tshuam rau Kev Sib Txuas | Cov txheej txheej tuab dua yuav tsum tau tho qhov ntau dhau kom haum rau cov fasteners, cuam tshuam rau kev khi kom ruaj ntseg. |
| Kev Tiv Thaiv Kev Xeb | Txheej zinc ntawm cov xov txiv neej tiv thaiv ob qho khoom los ntawm kev xeb txawm tias overtapping. |
Cov qauv kev lag luam teem cov kev txwv rau qhov tuab ntawm cov zinc txheej kom tiv thaiv teeb meem kev khi. Feem ntau, cov zinc plating muab ib txheej nyias nyias, ci ntsa iab, zoo rau cov fasteners me me hauv cov xwm txheej tsis hnyav. Kev kub-dip galvanizing tsim ib txheej tuab dua, uas ua haujlwm zoo dua hauv cov chaw ib puag ncig hnyav tab sis tuaj yeem ua rau kev khi nyuaj dua.
| Qhov Loj ntawm lub Fastener | Zinc Txheej Thickness (nti) | Yam tsawg kawg nkaus Thickness (nti) |
|---|---|---|
| Naj Npawb 8 thiab me dua | 0.00015 | Cov txheej nyias dua siv tau |
| Kev lag luam zinc-daj | 0.00020 | Cov txheej nyias dua siv tau |
| 3/8 nti txoj kab uas hla thiab me dua | 0.0017 | 0.0014 |
| Ntau tshaj 3/8 nti txoj kab uas hla | 0.0021 | 0.0017 |
- Kev lag luam zinc plating muaj qhov tuab tsawg kawg yog 0.00015 nti.
- Kev kub dip galvanizing muab cov txheej tuab dua thiab ruaj khov dua, txog li 1.0 hli tuab.
- Cov khoom siv zinc plated ua haujlwm tau zoo hauv qhov chaw tsis kub, tab sis cov khoom siv galvanized kub dipped zoo dua rau cov xwm txheej nyuaj.
Tsis Zoo Rau Kev Siv Siab Siab
Cov ntsia hlau thiab cov txiv ntoo uas raug galvanized tsis ua haujlwm zoo rau cov kev siv uas muaj kev ntxhov siab lossis kev thauj khoom hnyav. Tej zaum koj yuav pom teeb meem xws li tawg lossis ua tsis tiav sai sai yog tias koj siv lawv qhov chaw uas muaj zog heev.
Qhov kev pheej hmoo ntawm hydrogen embrittlement siab dua rau cov fasteners nrog lub zog tensile siab dua 150 ksi. Qhov teeb meem no ua rau cov hlau poob ductility thiab tawg ntxov. Cov qauv kev lag luam, xws li ASTM A143 thiab ASTM F2329, ceeb toom txog kev siv cov fasteners galvanized kub-dip rau cov haujlwm muaj zog siab.
Hauv cov chaw muaj kev ntxhov siab ntau, cov ntsia hlau galvanized tuaj yeem raug kev txom nyem los ntawm kev ntxhov siab corrosion tawg thiab hydrogen-induced cracking. Lawv lub zog tuaj yeem poob ntau dua 20% tom qab siv ntev. Cov hydrogen hauv cov ntsia hlau no tuaj yeem nce ntau dua 300%, ua rau lawv muaj feem yuav ua tsis tiav. Cov ntsia hlau coated muaj zog siab khaws lawv cov khoom siv kho tshuab zoo dua nyob rau hauv kev ntxhov siab.
Lus Cim:Rau cov choj, cov tshuab hnyav, lossis cov khoom txhawb nqa, koj yuav tsum xaiv cov khoom siv txuas uas ua los ntawm cov khoom siv muaj zog xws li hlau tsis xeb lossis hlau alloy.
Kev Txhawj Xeeb Txog Kev Sib Haum Xeeb Nrog Lwm Cov Khoom Siv
Koj yuav tsum xav txog qhov sib xws thaum siv cov ntsia hlau thiab cov txiv ntoo galvanized nrog lwm cov ntaub ntawv tsim kho. Qee qhov kev sib xyaw ua ke tuaj yeem ua rau xeb lossis cov tshuaj lom neeg ua rau koj txoj haujlwm tsis muaj zog.
Muaj ntau qhov chaw ywj pheej tau ceeb toom tias xeb dawb thiab liab sai sai thaum cov khoom siv galvanized kub kub raug sim nrog cov ntoo uas tsis kho nrog arsenate. Raws li daim ntawv tshaj tawm EPA, '[t]ntawm no yog ib qho kev sim uas ua los ntawm kev lag luam tsim kho vaj tse uas qhia tias txawm tias cov khoom siv kho vajtse uas tshaj tawm tias muaj kev tiv thaiv xeb zoo dua los pib qhia cov cim ntawm xeb hauv 1000 teev ntawm kev sim uas ua kom nrawm dua (sib npaug rau 16 xyoo ntawm kev raug teeb tsa) thaum siv nrog ntoo kho nrog ACQ.'
- Cov ntoo uas tau kho cov tshuaj tiv thaiv yuav tsis sib haum nrog cov ntsia hlau zinc thiab txhuas.
- Cov ntsia hlau stainless hlau lossis cov ntsia hlau kub dip galvanized ua raws li ASTM A153 Class D lossis hnyav dua ua haujlwm zoo tshaj plaws nrog cov ntoo kho.
- Thaum txuas cov hlau panels rau ntawm cov ntoo uas tau kho, koj tuaj yeem siv cov khoom thaiv dej noo ntawm cov ntoo thiab cov vaj huam sib luag.
- Cov khoom siv txuas uas tsis sib xws suav nrog cov ntsia hlau zinc plated, cov ntsia hlau zinc-alloy headed, thiab cov ntsia hlau stainless capped.
Cov tshuaj lom neeg kuj tseem tuaj yeem tshwm sim ntawm cov txheej galvanized thiab cov pob zeb ua vaj tse, tshwj xeeb tshaj yog thaum lub sijhawm kho. Cov txheej txheem no tso tawm cov pa hydrogen thiab ua rau lub zog ntawm cov hlau galvanized thiab cov pob zeb ua vaj tse tsis muaj zog. Kev kho chromate pab txo cov teeb meem no.
Ceeb Toom:Ib txwm xyuas seb koj cov khoom siv sib haum nrog cov khoom siv hauv koj qhov project. Kev siv cov khoom sib xyaw tsis raug tuaj yeem ua rau xeb thaum ntxov, cov pob qij txha tsis muaj zog, lossis txawm tias cov qauv tsis ua haujlwm.
