Lub ntsiab drawbacks ntawm Galvanized Hardware
Hydrogen Embrittlement Risk
Koj yuav tsum paub txoghydrogen embrittlementua ntej xaiv galvanized screws thiab ceev. Qhov teeb meem no tshwm sim thaum hydrogen nkag mus rau hauv cov hlau thiab ua rau nws nkig. Cov hlau brittle tuaj yeem tawg lossis tawg hauv kev ntxhov siab.
Ntau yam ua rau muaj kev pheej hmoo ntawm hydrogen embrittlement:
- Corrosion, tshwj xeeb tshaj yog nyob rau hauv acidic los yog salty ib puag ncig, generates hydrogen ntawm hlau nto.
- Cov dej noo ua lub luag haujlwm tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas muaj av noo siab.
- Kev raug thaum lub sij hawm tsim kho, zoo li ua hauj lwm nyob rau hauv ntub dej, yuav ua rau kom hydrogen nkag mus.
- Cov kev pabcuam uas tsis paub meej lossis cov av noo siab ua rau muaj kev pheej hmoo.
Koj kuj ntsib kev pheej hmoo siab dua thaum peb yam no tshwm sim ua ke:
- Hydrogen yog tam sim no.
- Lub fastener nyob rau hauv tas li load los yog kev ntxhov siab.
- Cov khoom yog raug, tshwj xeeb tshaj yog muaj zog steel.
Kev ntxhov siab tsis xav tau thaum lub sijhawm teeb tsa tuaj yeem ua rau cov ntsia hlau ntau dhau thiab ua rau muaj kev cuam tshuam ntau dua. Koj yuav tsum tswj hwm qhov chaw muaj kev ntxhov siab thiab zam dhau kev nruj nruj.
Tswv yim:Yog tias koj siv galvanized fasteners nyob rau hauv ntub dej los yog corrosive ib puag ncig, xyuas cov cim ntawm kev tawg los yog poob ntawm lub zog lub sij hawm.
Fastening Teeb meem los ntawm Zinc Txheej Thickness
Galvanized screws thiab txiv ntseej muaj zinc txheej tuab. Cov txheej no tiv thaiv xeb, tab sis nws tuaj yeem ua rau muaj teeb meem thaum koj sim khi qhov chaw ua ke. Lub thickness ntawm zinc txheej tuaj yeem ua rau cov ntsia hlau thiab cov txiv ntseej nyuaj kom haum rau hauv qhov lossis cov xov.
| Yam | Paub meej |
|---|---|
| Zinc Txheej ThicknessNtau yam | 45-65 hli |
| Kev cuam tshuam rau Fastening | Thicker coatings yuav tsum tau overtapping ntawm qhov kom haum cov fasteners, cuam tshuam kev ruaj ntseg fastening. |
| Kev tiv thaiv corrosion | Zinc txheej ntawm txiv neej threads tiv thaiv ob qho tib si ntawm corrosion txawm tias overtapping. |
Cov txheej txheem kev lag luam tau teeb tsa kev txwv rau zinc txheej thickness los tiv thaiv teeb meem fastening. Zinc plating feem ntau muab cov txheej nyias nyias, ci ntsa iab, zoo rau cov fasteners me me hauv cov mob me. Kub-dip galvanizing tsim ib txheej tuab ntau, uas ua haujlwm zoo dua hauv qhov chaw hnyav tab sis tuaj yeem ua kom nrawm dua.
| Fastener Loj | Zinc Txheej Thickness (inch) | Yam tsawg kawg nkaus Thickness (inch) |
|---|---|---|
| No.8 thiab me dua | 0.00015 | Thinner txheej tau txais |
| Kev lag luam zinc-daj | 0.00020 | Thinner txheej tau txais |
| 3/8 nti diam thiab me dua | 0.0017 Nws | 0.0014 |
| Tshaj 3/8 nti diam | 0.0021 ib | 0.0017 Nws |
- Kev lag luam zinc plating muaj qhov tsawg kawg nkaus thickness ntawm 0.00015 nti.
- Kub dip galvanizing muab cov txheej tuab thiab ruaj khov dua, txog 1.0 hli tuab.
- Zinc plated fasteners ua haujlwm zoo nyob rau hauv ib puag ncig me me, tab sis kub-dipped galvanized fasteners zoo dua rau cov mob hnyav.
Tsis zoo rau kev siv kev ntxhov siab
Galvanized screws thiab txiv ntseej tsis ua haujlwm zoo hauv cov ntawv thov kev ntxhov siab lossis cov kabmob load. Koj tuaj yeem pom cov teeb meem xws li tawg lossis tsis ua haujlwm tam sim yog tias koj siv lawv qhov chaw muaj zog.
Qhov kev pheej hmoo ntawm hydrogen embrittlement yog siab dua rau fasteners nrog tensile lub zog siab tshaj 150 ksi. Qhov teeb meem no ua rau cov hlau poob ductility thiab tawg thaum ntxov. Cov qauv kev lag luam, xws li ASTM A143 thiab ASTM F2329, ceeb toom tiv thaiv kev siv kub-dip galvanized fasteners rau kev ua haujlwm siab.
Nyob rau hauv ib puag ncig kev nyuaj siab, galvanized bolts tuaj yeem raug kev nyuaj siab corrosion cracking thiab hydrogen-induced cracking. Lawv lub zog tuaj yeem poob ntau dua 20% tom qab siv mus ntev. Cov ntsiab lus hydrogen hauv cov bolts tuaj yeem nce ntau dua 300%, ua rau lawv yuav ua tsis tiav. High-strength coated bolts khaws lawv cov cuab yeej cuab tam zoo dua nyob rau hauv kev ntxhov siab.
Nco tseg:Rau cov txuas hniav, cov tshuab hnyav, lossis kev txhawb nqa cov qauv, koj yuav tsum xaiv cov fasteners ua los ntawm cov ntaub ntawv muaj zog xws li stainless hlau lossis hlau alloy.
Compatibility Kev txhawj xeeb nrog lwm cov ntaub ntawv
Koj yuav tsum xav txog kev sib raug zoo thaum siv galvanized screws thiab txiv ntseej nrog lwm cov khoom siv hauv tsev. Qee qhov sib xyaw ua ke tuaj yeem ua rau xeb lossis tshuaj lom neeg uas ua rau koj qhov project tsis muaj zog.
Ntau qhov chaw ywj pheej tau ceeb toom tias cov xim dawb thiab xim liab ua sai sai thaum kub dipped galvanized fasteners raug kuaj nrog cov ntoo uas tsis yog arsenate. Raws li tsab ntawv ceeb toom EPA, '[t] ntawm no tau ua ib qho kev ntsuas hnub nyoog nrawm ua los ntawm kev lag luam hauv tsev uas qhia tau tias txawm tias cov khoom siv uas tshaj tawm cov kev txhim kho corrosion pib pom cov tsos mob ntawm xeb nyob rau hauv 1000 teev ntawm lub hnub nyoog-accelerated xeem (sib npaug rau 16 xyoo ntawm kev teeb tsa raug) thaum siv nrog . ACQ-treated.
- Preservative-kho ntoo tuaj yeem ua tsis tau nrog zinc plated screws thiab txhuas.
- Stainless hlau fasteners lossis kub dip galvanized rau tes ua rau ASTM A153 Class D lossis hnyav ua haujlwm zoo tshaj plaws nrog cov ntoo kho.
- Thaum txuas hlau panels rau cov ntoo kho, koj tuaj yeem siv cov dej noo thaiv ntawm cov ntoo thiab lub vaj huam sib luag.
- Fasteners uas tsis sib xws suav nrog zinc plated screws, zinc-alloy headed screws, thiab stainless capped screws.
Cov tshuaj tiv thaiv kuj tuaj yeem tshwm sim ntawm galvanized coatings thiab pob zeb, tshwj xeeb tshaj yog thaum kho. Cov txheej txheem no tso tawm cov pa roj hydrogen thiab ua kom tsis muaj zog ntawm cov galvanized rebar thiab pob zeb. Kev kho chromate pab txo cov teeb meem no.
Ceeb toom:Nco ntsoov xyuas qhov sib haum ntawm koj cov fasteners nrog cov ntaub ntawv hauv koj qhov project. Kev siv cov kev sib xyaw ua ke tsis zoo tuaj yeem ua rau xeb thaum ntxov, cov pob qij txha tsis muaj zog, lossis txawm tias cov txheej txheem tsis ua haujlwm.
Thaum Yuav Siv Galvanized Screws thiab Ceev
Qhov zoo tshaj plaws Project Applications
Koj tau txais tus nqi tshaj plaws los ntawmgalvanized screws thiab ceevnyob rau hauv tej yaam num uas ntsib huab cua, ya raws, los yog sab nraum zoov raug. Cov kws tshaj lij kev lag luam pom zoo kom cov fasteners no rau ntau qhov kev siv tseem ceeb:
- Sab nraum zoov tej yaam num: Koj tuaj yeem siv galvanized screws rau laj kab, decks, thiab rooj tog sab nraum zoov. Lawv cov kev tiv thaiv corrosion ua rau koj txoj haujlwm muaj zog txawm tias nag lossis hnub.
- Kev tsim kho vaj tse: Cov neeg tsim khoom feem ntau xaiv galvanized fasteners rau cov qauv thav duab thiab kev tsim kho. Koj tau txais txiaj ntsig los ntawm lawv cov kav ntev thiab tus nqi qis dua.
- Woodwork thiab Decking: Galvanized screws ua haujlwm zoo nrog cov ntoo kho. Lawv pab tiv thaiv stains thiab ntoo puas thaum lub sij hawm.
Tswv yim:Cov cai hauv tsev feem ntau xav tau kub-dipped galvanized, stainless hlau, los yog silicon bronze fasteners rau tej yaam num nrog preservative-kho ntoo. Rau vov tsev, koj yuav tsum siv galvanized fasteners kom ua tau raws li cov qauv kev nyab xeeb.
| Hom ntawv thov | Fastener Requirement |
|---|---|
| vov tsev | Galvanized fasteners rau steel ru tsev |
| Preservative-Thiab Ntoo | Kub-dipped galvanized steel, stainless hlau, silicon bronze, los yog tooj liab fasteners yuav tsum tau. |
Thaum twg los xav txog lwm txoj kev
Koj yuav tsum saib lwm hom fastener yog tias koj qhov project ntsib kev ntxhov siab, tshuaj lom neeg, lossis dej ntsev. Stainless hlau fasteners ua haujlwm zoo tshaj plaws rau kev ua dej hiav txwv, kev ua zaub mov, lossis chaw kho mob. Lawv kav ntev dua thiab tiv thaiv xeb zoo dua li cov hlau galvanized, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.
| Fastener Hom | Zoo tshaj rau | Pros | Cons |
|---|---|---|---|
| Stainless hlau | Marine, zaub mov, kho mob, sab nraum zoov | Ntev ntev, corrosion-resistant | Tus nqi siab dua |
| Zinc Plating | Qhuav, ib puag ncig me me | Nqis, yooj yim xeb tiv thaiv | Tsis yog rau qhov hnyav lossis ntub dej |
| Phosphate Txheej | Tub rog, automotive, industrial | Zoo lubrication nrog roj | Nruab nrab corrosion kuj |
Galvanized txheej tiv thaiv cov hlau hauv dej hiav txwv, tab sis ntsev thiab tshuaj tuaj yeem hnav sai sai. Stainless hlau muab kev ua tau zoo rau lub sijhawm ntev hauv cov chaw tawv no. Xaiv lub fastener txoj cai rau koj ib puag ncig kom koj qhov project muaj kev nyab xeeb thiab muaj zog.
