I-Hydrogen Embrittlement: Ukuqonda kunye nokunciphisa iPhenomenon

Intshayelelo:

I-Hydrogen embrittlement ibaluleke kakhulu kwishishini lamandla e-hydrogen, echaphazela ingqibelelo yezisombululo zokugcina, ngakumbi iinqanawa ezinoxinzelelo oluphezulu.isilindas. Esi siganeko senzeka xa ukutyhileka kwirhasi yehidrojeni kusenza iintsimbi, ngakumbi iintsimbi zokuqina okuphezulu, zibe brittle kwaye zithande ukuqhekeka. Eli nqaku liphonononga izizathu ze-hydrogen embrittlement, izicwangciso zokunciphisa, impembelelo yayo kwizisombululo zokugcina i-hydrogen, kunye nezikhokelo zokusetyenziswa.uhlobo lwe-3 cylinders yokugcina ihydrogen.

Ukuqonda i-Hydrogen Embrittlement:

I-Hydrogen embrittlement ivela ekusasazweni kwe-hydrogen kwi-crystal lattice yesinyithi, iphazamisa ukukwazi kwayo ukukhubaza iplastiki kwaye iyenze ibe brittle. Ukuqhekeka okubangelwa uxinzelelo kunokwenzeka phantsi koxinzelelo oluphezulu okanye imithwalo enzima.

IziCwangciso zokuNciphisa:

1-Ukhetho Lwezinto:Khetha izinto ezixhathisa i-hydrogen, njenge-alloys ezithile kunye neengubo.
2-Ukunciphisa uxinzelelo:Ukunciphisa uxinzelelo lwengqondo kumacandelo ukunciphisa umngcipheko wokuqhekeka.
3-IiMeko zokuTshaja ngeHydrojeni:Lawula kwaye ubeke iliso kwiimeko zokutshaja i-hydrogen ukunqanda ukuba sesichengeni ngokugqithisileyo.
4-Ulawulo lobushushu:Gcina amaqondo obushushu okusebenza ngaphakathi koluhlu olunciphisa ukunyuswa kwehydrogen.

Impembelelo kwiZisombululo zoGcino lweHydrojeni:

I-hydrogen embrittlement yinto ebalulekileyo, ngakumbi kwizisombululo zokugcina uxinzelelo oluphezuluisilindas. I-embrittlement inokuphazamisa ingqibelelo ye-cylinder, ekhokelela ekungaphumelelini okunokwenzeka kunye nemingcipheko yokhuseleko.

Iinkxalabo ngokuSetyenziswa kweSilinda:

1-Imfezeko yezinto:Ukuhlola rhoqo iisilinda ngeempawu zomonakalo owenziwe yi-embrittlement.
2-Ukucoceka kweHydrojeni:Qinisekisa ukucoceka kwehydrogen egciniweyo ukunciphisa imingcipheko ye-embrittlement.
3-Imiqathango yokuSebenza:Gcina iimeko zokusebenza ezifanelekileyo, kubandakanywa uxinzelelo kunye nobushushu, ukunciphisa i-embrittlement.

UkusebenzisaUhlobo lwe-3 Cylinders yoGcino lweHydrojeni:

Uhlobo lwe-3 cylinders, ebonisa i-aluminiyam liner esongelwe kwi-carbon fiber, idla ngokusetyenziselwa ukugcina i-hydrogen. Qwalasela ezi zikhokelo zilandelayo zokusetyenziswa ngokukhuselekileyo:

1-Ukuhambelana:I-Aluminiyam liner ibonelela ngomqobo ngokuchasene ne-hydrogen permeation, kunye ne-carbon fiber wraps yongeza amandla.
2-Imfezeko yezinto:Hlola rhoqo isilinda ukuze ubone naziphi na iimpawu zomonakalo, ukubola, okanye ukuguga.
3-Uxinzelelo kunye nobushushu:Namathela kuxinzelelo olucetyiswayo kunye neenkcukacha zobushushu ukuze ugcine ngokukhuselekileyo.
4-Ukucoceka kweHydrojeni:Qinisekisa ukucoceka okuphezulu kwe-hydrogen ukukhusela imiphumo emibi kwizinto ze-cylinder.
5-Ukuthotyelwa kweMimiselo:Landela imigangatho yokhuseleko kunye nemimiselo, efana ne-ISO 11439 kunye ne-ISO 15869.
6-Uvavanyo lweXesha:Yenza uvavanyo lwe-hydrostatic ngamaxesha athile ukuvavanya imfezeko yesakhiwo.
7-Izikhokelo zabavelisi:Landela izikhokelo ezithile ezinikezelwe ngumenzi we-cylinder.

Iingqwalasela zezoThutho:Ukuba i-cylinder isetyenziselwa ukuthutha, thobela imimiselo esebenzayo yokuthutha ngokukhuselekileyo kweegesi eziphezulu.

Isiphelo:

Ngelixauhlobo lwe-3 cylinders ziyilelwe ugcino lwerhasi enoxinzelelo oluphezulu kwaye zisetyenziselwe ngempumelelo ukugcina i-hydrogen, kubalulekile ukukhuthala ukubambelela kwimigaqo yokhuseleko kunye nezikhokelo. Ukuqonda kunye nokujongana ne-hydrogen embrittlement kubaluleke kakhulu ekuqinisekiseni ukhuseleko kunye nobomi obude bezisombululo zokugcina i-hydrogen. Ngokuphumeza ukhetho olomeleleyo lwezixhobo, ukubeka iliso, kunye nezenzo zokusebenza, ishishini lingajongana nalo mceli mngeni kwaye liqhubele phambili kwikamva elikhuselekileyo nelizinzileyo le-hydrogen.
