Tom qab kos cim kev lag luam yog ib qho tseem ceeb heev rau kev tiv thaiv kav dej.
Passivation:
Peb muaj peb tus kheej kev tsim kho patent hauv cov txheej txheem passivationlawv- passivation kua tsis siv neeg txau tshuab. Nws tuaj yeem muajxyuas kom meej qhov sib thooj ntawm cov kua ua pa ntawm lub yeeb nkab nto. Lub caij no peb siv lub tshuab ua kua passivation zoo. Cov yeeb nkab saum npoo yog zoo nkauj dua thiab kev tiv thaiv ua tau zoo dua.
Txhua qhov kev txiav txim yeeb nkab yuav nyob rau hauv qhov ntsuas tshuaj tsuag ntsev thiab peb cov yeeb nkab tuaj yeem ua kom ntev kawg tsawg kawg yog 8 teev yam tsis muaj xeb.
Yog tias peb tsis muaj qhov passivation los yog siv qhov tsis zoo (pheej yig) passivation kua,
dab tsi yuavhappen?
Cia’s pom daim duab.
Tom qab lub sijhawm luv luv khaws cia, peb tuaj yeem pom qhov sib txawv. Peb cov yeeb nkab tseem zoo tag nrho. Tab sis cov
lwm qhov ib qho uas tsis muaj pa uas ua kom tsis muaj zog tau xeb.
Nws tsis tsuas yog enfluences saum npoo, tab sis kuj enfluences siv lub neej.
Tom qabtuspassivation, peb kuj muaj ib tugoiled precessing hauv cov kab ntau lawm uas tuaj yeem ntsaws cov yeeb nkab raucov qhua tuaj noj movpab dawb. Tab sis usuallypebgalvanized yeeb nkab tsis xav tau ua cov roj txheej txheem. Tab sis yog tias ib tus neeg yuav tsum tau ua cov kev tiv thaiv no, nws tsis yog teeb meem.
