Lub Metallurgy thiab Corrosion Science ntawm Percussion Earth Anchors

Lub Metallurgy thiab Corrosion Science ntawm PercussionNtiaj Teb Anchors
Nyob rau hauv siab -voltage transmissions, telecommunications grids, and civil infrastructure, the structural integrity of guyed towers nyob ntawm tag nrho cov hauv qab no- hauv av foundations. Txawm hais tias feem ntau ntawm kev tsom xam engineering tau muab tso rau ntawm kev thauj khoom- xauv tshuab thiab av dynamics, qhov kawg ciaj sia taus ntawm cov txheej txheem thauj tog rau nkoj tshaj 30-rau-50-xyoo kev pabcuam lub neej los ntawm metallurgical zoo thiab corrosion science.
Rau cov thawj coj ntawm kev yuav khoom thiab cov kws tsim qauv tsim qauv, qhia txog txoj cai percussion lub ntiaj teb thauj tog rau nkoj yuav tsum tau saib tob rau hauv cov txheej txheem tsim khoom, steel chemistry, thiab cov txheej txheem tiv thaiv kom tsis txhob muaj kev puas tsuaj hauv av.
1. Qhov Kev Nyuaj Siab Hauv Ntiaj Teb: Vim li cas Standard Steel Fail
Lub ntiaj teb anchors khiav lag luam nyob rau hauv ib qho ntawm feem ntau hostile ib puag ncig paub rau industrial hardware. Thaum uas tau tsav hauv qab ntawm qhov chaw, cov pas nrig thauj tog rau nkoj tau raug rau cov dej cawv tas li ntawm cov dej noo, oxygen, organic acids, thiab cov av tsis sib xws electrolytes.

Pitting thiab Uniform Corrosion: Hauv cov av txhoj puab heev (xws li cov av nplaum acidic lossis cov dej ntsev ib puag ncig), cov pa roj carbon hlau tsis muaj kev tiv thaiv ua rau oxidation sai. Sij hawm dhau mus, hauv zos pitting txo tus ntoo khaub lig zoo -sectional txoj kab uas hla ntawm lub thauj tog rau nkoj pas nrig, txo qis nws tensile tawm los zog kom txog rau thaum nws snaps nyob rau hauv cua daj cua dub- induced nro.
Lub Vulnerability ntawm High-Strength Alloys: Txhawm rau txhawb nqa cov khoom siv loj, cov pas nrig thauj tog rau nkoj yog tsim los ntawm siab - tensile steel. Txawm li cas los xij, cov qib steel siab dua yog qhov muaj feem cuam tshuam rau ib puag ncig kev ntxhov siab corrosion tawg yog tias muaj kev tiv thaiv zoo metallurgical tsis saib xyuas thaum tsim khoom.

2. Cov qauv tsim khoom: Cov ntaub thaiv npog kub-Dip Galvanizing (HDIP)
Txhawm rau ua kom tiav ib nrab - xyoo pua lub neej kev pabcuam, kev sib twntiaj teb thauj tog rau nkojs yuav tsum muaj kev tiv thaiv los ntawm metallurgically bonded barrier uas tuaj yeem tiv taus kev sib txhuam ntawm kev tsav tsheb thiab cov av hauv av puas.
ASTM A153 Standard: Cov tuam txhab muaj koob npe nruj ua raws li cov txheej txheem galvanizing nruj, xws li ASTM A153, uas txiav txim siab qhov hnyav thiab tuab ntawm zinc- hlau alloy txheej siv los ntawm Kub-Dip Galvanizing.
Kev Tiv Thaiv Kev Txhaum Cai Anode: Zinc muaj peev xwm ua tau hluav taws xob ntau dua li cov hlau. Txawm hais tias cov txheej txheem thauj tog rau nkoj muaj kev khawb me me thaum lub sij hawm siab - cuam tshuam tsav tsheb, cov zinc nyob ib puag ncig ua ib qho kev txi, cathodically tiv thaiv cov hlau raug thiab tiv thaiv xeb.
3. Tshem tawm qhov Tsis Pom Zoo: Hydrogen De-Embrittlement Baking
Raws li kev tshawb fawb hauv kev ua cov hlau nplaum siab heev, ib qho ntawm cov kev pheej hmoo zais hauv kev tsim khoom siab -cov khoom siv hluav taws xob muaj zog yog Hydrogen Embrittlement.
Thaum lub sij hawm cov kua qaub -pickling ua ntej- kev kho mob theem ntawm galvanizing, hydrogen atoms yuav diffuse mus rau hauv lub siab - lub zog steel qauv.
Yog tias sab laug tsis kho, qhov khoob hydrogen no tsim cov micro- tawg, ua rauntiaj teb thauj tog rau nkojpas nrig rau kev txom nyem tsis ua hauj lwm nyob rau hauv dynamic shock loads (xws li cua daj cua dub hnyav).
Cov kws tshaj lij kev lag luam tswj hwm nruj, sijhawm- tswj kev tshaj tawm- galvanizing ci (de-embrittlement) lub voj voog kom muaj kev nyab xeeb tsav tawm cov pa nqus hydrogen, ua kom cov hlau khaws nws qhov tseem ceeb ductility yam tsis muaj kev cuam tshuam lub zog tensile.

Q: Yuav ua li cas kub-dip galvanizing tiv thaiv kev sib txhuam ntawm kev tsav mus rau hauv cov av pob zeb?

A:Kub-dip galvanizing tsim ntau- txheej metallurgical daim ntawv cog lus uas muaj cov zinc txheej sab nraud thiab cov zinc sab hauv- hlau alloy txheej. Qhov no tsim ib qho nyuaj, abrasion- tiv thaiv cov ntaub thaiv npog uas tiv thaiv stripping txawm tias tau tsav los ntawm cov pob zeb tuab thiab cov strata.

Q: Puas tuaj yeem xeb tuaj yeem tshwm sim ntawm qhov chaw sib txuas uas cov pas nrig thauj tog rau nkoj ntsib tus txiv neej hlau saum av?

A:Yog lawm. Qhov chaw hloov pauv ntawm av thiab huab cua (qhov chaw txaws / aeration) ua rau muaj kev cuam tshuam sai vim muaj cov pa oxygen. Ua kom tiav galvanization kev pab them nqi raws tag nrho cov pas nrig thiab siv corrosion-cov txiv ntseej resistant hardware yog qhov tseem ceeb.

Q: Vim li cas pawg neeg yuav khoom xav tau daim ntawv pov thawj zeb xeem (MTC) rau lub ntiaj teb thauj tog rau nkoj?

A:Cov ntawv pov thawj zeb kuaj xyuas cov tshuaj muaj pes tsawg leeg, lub zog tensile, thiab ua raws li cov qauv galvanizing, kom ntseeg tau tias cov thauj tog rau nkoj muab yuav ua tau raws li cov qauv kev nyab xeeb raws li qhov tiag - lub ntiaj teb kev ua haujlwm.
