Ua thiab Tiv Thaiv Corrosion ntawm Rail Bolts
Dab tsi yog qhov tseem ceeb ntawm corrosion ntawm cov bolts?
Cov dej nag, dej noo, tshuaj tsuag ntsev, de- cov tshuaj tiv thaiv kab mob, cov kua qaub los nag, cov plua plav, cov dej ntws tawm, thiab lwm yam, tuaj yeem ua rau oxidation thiab electrochemical corrosion ntawm lub ntsia liaj qhov rooj.
Dab tsi yog qhov phom sij ntawm bolt corrosion?
Xov jamming, nyuaj hauv disassembly thiab sib dhos, tsis raug torque, txo lub zog, thiab yooj yim tawg cuam tshuam rau kev ruaj ntseg ntawm fasteners thiab pob qij txha, ua rau kev tu ncua nyuaj thiab kev nyab xeeb txaus ntshai.
Dab tsi yog qee yam kev tiv thaiv bolt corrosion?
Kub-dip galvanizing, Dacromet txheej, zinc- txhuas txheej, stainless hlau cov ntaub ntawv, xov corrosion grease, composite anti-corrosion txheej, thiab lwm yam.
Vim li cas kev tiv thaiv corrosion tseem ceeb dua rau siab - lub zog bolts?
High- lub zog bolts muaj lub zog siab thiab muaj kev cuam tshuam ntau dua rau kev ntxhov siab corrosion. Corrosion yooj yim ua rau hydrogen embrittlement thiab qaug zog tawg, ua rau muaj kev nyab xeeb ntau dua.
Yuav ua li cas ncua bolt corrosion ntawm -site?
Xaiv cov corrosion-cov ntsia hlau tiv taus, siv xeb- tiv thaiv roj, khaws cov ntsia hlau kom huv si thiab qhuav, kho tam sim ntawd cov coatings puas, thiab tsis tu ncua hloov bolts nyob rau hauv cov corroded loj.
