Taw qhia:
Hydrogen embrittlement yog ib qho tseem ceeb hauv kev lag luam hydrogen zog, cuam tshuam rau kev ncaj ncees ntawm cov kev daws teeb meem, tshwj xeeb tshaj yog cov hlab ntsha siab xws lilub tog raj kheejs. Qhov tshwm sim no tshwm sim thaum raug cov roj hydrogen ua rau cov hlau, tshwj xeeb tshaj yog cov hlau muaj zog, nkig thiab ua rau tawg. Kab lus no tshawb txog qhov ua rau hydrogen embrittlement, cov tswv yim txo qis, nws cuam tshuam rau hydrogen cia daws, thiab cov lus qhia sivhom 3 lub tog raj kheejs rau hydrogen cia.
Nkag siab txog Hydrogen Embrittlement:
Hydrogen embrittlement tshwm sim los ntawm diffusion ntawm hydrogen mus rau hauv cov hlau siv lead ua lattice, cuam tshuam nws lub peev xwm deform plastically thiab ua rau nws nkig. Kev ntxhov siab vim tawg tuaj yeem tshwm sim nyob rau hauv kev ntxhov siab lossis tensile loads.
Mitigation Strategies:
1-Kev xaiv khoom:Xaiv cov khoom siv hydrogen-resistant, xws li cov alloys tshwj xeeb thiab txheej txheej.
2-Txoj Kev Nyuaj Siab:Txo cov kev ntxhov siab hauv cov khoom siv kom txo tau qhov kev pheej hmoo ntawm kev tawg.
3-Hydrogen Charging Conditions:Tswj thiab saib xyuas hydrogen charging tej yam kev mob kom tsis txhob raug ntau dhau.
4-Kev tswj qhov kub thiab txias:Khaws qhov kub thiab txias ua haujlwm nyob rau hauv ib qhov chaw uas txo cov hydrogen embrittlement.
Kev cuam tshuam rau Hydrogen Storage Solutions:
Hydrogen embrittlement yog ib qho tseem ceeb rau kev xav, tshwj xeeb tshaj yog nyob rau hauv high-pressure cia daws xws lilub tog raj kheejs. Lub embrittlement tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm lub tog raj kheej, ua rau muaj peev xwm ua tsis tiav thiab muaj kev nyab xeeb.
Kev txhawj xeeb rau kev siv lub tog raj kheej:
1-Material Integrity:Tsis tu ncua tshuaj lub tog raj kheej rau cov cim qhia ntawm embrittlement-induced puas.
2-Hydrogen Purity:Xyuas kom meej qhov purity ntawm khaws cia hydrogen kom txo tau embrittlement txaus ntshai.
3-Kev Ua Haujlwm:Ua kom pom kev ua haujlwm zoo, suav nrog lub siab thiab qhov kub thiab txias, txhawm rau txo qis embrittlement.
SivHom 3 Lub tog raj kheejs rau Hydrogen Cia:
Hom 3 lub tog raj kheejs, featuring aluminium liner qhwv hauv carbon fiber, feem ntau yog siv rau hydrogen cia. Xav txog cov lus qhia hauv qab no rau kev siv nyab xeeb:
1-Compatibility:Aluminium liner muab kev thaiv kev tiv thaiv hydrogen permeation, thiab cov pa roj carbon fiber ntau pab txhawb lub zog.
2-Material Integrity:Tsis tu ncua tshuaj xyuas lub tog raj kheej kom paub meej tias muaj kev puas tsuaj, corrosion, lossis hnav.
3- Siab thiab kub:Ua raws li cov lus pom zoo thiab qhov kub thiab txias tshwj xeeb rau kev ruaj ntseg cia.
4-Hydrogen Purity:Xyuas kom lub siab purity hydrogen los tiv thaiv kev tsis zoo ntawm lub tog raj kheej cov khoom.
5-Txoj Cai Ua Raws Cai:Ua raws li cov qauv kev nyab xeeb thiab cov cai, xws li ISO 11439 thiab ISO 15869.
6- Kev Ntsuas Lub Sij Hawm:Ua kev sim hydrostatic ib ntus txhawm rau txheeb xyuas cov qauv kev ncaj ncees.
7- Cov Lus Qhia Txog Tus Neeg Tsim Khoom:Ua raws li cov lus qhia tshwj xeeb muab los ntawm lub tog raj kheej tsim khoom.
Kev txiav txim siab txog kev thauj mus los:Yog tias lub tog raj kheej siv rau kev thauj mus los, ua raws li cov kev cai siv rau kev nyab xeeb ntawm kev thauj mus los ntawm cov roj cua siab.
Xaus:
Thaumhom 3 lub tog raj kheejs yog tsim los rau kev cia siab rau cov pa roj thiab tau ua tiav zoo rau kev khaws cia hydrogen, nws yog ib qho tseem ceeb uas yuav tsum tau mob siab rau ua raws li cov txheej txheem kev nyab xeeb thiab cov lus qhia. Kev nkag siab thiab hais txog hydrogen embrittlement yog qhov tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab siv tau ntev ntawm hydrogen cia daws teeb meem. Los ntawm kev siv cov khoom siv zoo, kev saib xyuas, thiab kev ua haujlwm, kev lag luam tuaj yeem taug kev qhov kev sib tw no thiab nce mus rau kev nyab xeeb thiab muaj kev nyab xeeb dua hydrogen yav tom ntej.
