Hauv kev kho thiab kho dua cov khoom siv hauv kev lag luam, kev ncua lub neej ua haujlwm ntawm cov khoom uas raug kev puas tsuaj loj heev yog ib qho kev sib tw tas li.Kev Sib Txuas Ncejyog ib lub electrode tshwj xeeb uas siv tau uas tsim los rau cov txheej txheem hardfacing, qhov twg ib txheej tiv thaiv alloy raug tso rau ntawm qhov chaw hlau kom txhim kho nws lub zog. Cov electrodes vuam ntawm cov qauv xws li B-85 tau tsim tshwj xeeb los tiv taus kev hnav hnyav, kev sib txhuam, thiab kev cuam tshuam nruab nrab, uas yog qhov tseem ceeb rau kev tiv thaiv cov khoom siv kho tshuab tseem ceeb.
Qhov kev ua tau zoo tseem ceeb ntawm Surfacing Welding Rod no yog los ntawm nws cov txheej chromium siab thiab cov tshuaj lom neeg tso tawm. Lub electrode muaj cov txheej nplua nuj hauv chromium, uas pab txhawb rau qhov nyuaj thiab tiv taus corrosion ntawm cov weld deposit. Cov khoom sib xyaw no tso cai rau cov txheej surfaced kom tswj tau nws cov khoom tiv thaiv txawm tias nyob rau hauv qhov kub siab thiab nyob rau hauv cov huab cua corrosive. Cov deposit tshwm sim yog tsim los tiv taus kev sib txhuam tas li thiab kev sib txhuam hnyav, zoo tiv thaiv cov khoom siv hauv qab.
Nws yog ib qho tseem ceeb kom nkag siab txog qhov kev siv zoo tshaj plaws thiab cov kev txwv ntawm cov khoom no. Thaum lubKev Sib Txuas Ncejxws li B-85 zoo heev tiv thaiv kev hnav thiab kev cuam tshuam nruab nrab, nws tsis pom zoo rau cov ntawv thov uas muaj kev poob siab loj lossis kev ntaus hnyav. Nws lub luag haujlwm tseem ceeb yog los tsim kom muaj ib qho tawv, hnav-resistant overlay es tsis yog nqus cov kev cuam tshuam zog siab. Kev xaiv daim ntawv thov kom raug yog qhov tseem ceeb kom ntseeg tau tias lub neej ntev ntawm ob qho tib si hardfaced txheej thiab cov khoom nws tiv thaiv.
Cov txheej txheem ua haujlwm suav nrog kev siv cov txheej txheem arc welding (SMAW). Cov Qws Vuam Surfacing no siv ua tus pas vuam tes, xav tau tus kws vuam txawj siv nws kom zoo. Cov txheej txheem suav nrog kev tso cov hlau sib xyaw rau ntawm qhov chaw ua haujlwm uas tau npaj tseg los tsim ib txheej tiv thaiv. Cov ntawv thov ib txwm muaj xws li kev tsim kho dua tshiab cov khoom siv xws li crusher hammers, twj tso kua mis impellers, augers, thiab lwm yam khoom siv hauv kev tsuas, kev ua liaj ua teb, thiab kev tuav cov khoom siv uas qhov chaw puas tsuaj yog hom kev ua tsis tiav tseem ceeb.
Lub B-85Kev Sib Txuas Ncejmuab ib qho kev daws teeb meem rau kev tawm tsam qhov hnav ntawm qhov chaw los ntawm kev vuam arc. Nws tus nqi nyob rau hauv cov nyiaj tso cia siab-chromium uas tiv taus kev puas tsuaj thiab ua haujlwm hauv qhov chaw nyuaj, yog tias nws siv rau hauv nws qhov kev tsim qauv.—zam kev cuam tshuam loj heev. Rau kev ua haujlwm tsom mus rau kev saib xyuas tiv thaiv thiab kev kho dua tshiab ntawm cov khoom, tus pas nrig vuam no ua haujlwm ua lub cuab yeej siv tau zoo rau kev siv qhov chaw ruaj khov, tiv thaiv rau cov khoom hlau uas tsis muaj zog.
