Tiv thaiv xeb ntawm Railway Tracks
Kev ua kom ruaj khov thiab kev nyab xeeb ntawm kev tsheb ciav hlau yog qhov tseem ceeb, thiab kev tiv thaiv xeb yog qhov tseem ceeb rau kev ua tiav lub hom phiaj no. Cov txheej txheem muaj xws li siv cov txheej tiv thaiv thiab cov xim ua los ntawm cov ntaub ntawv xws li epoxy, polyurethane, lossis acrylic. Cov txheej txheej no ua raws li kev thaiv, tiv thaiv cov hlau nto los ntawm ya raws thiab oxygen kom tsis txhob xeb. Lwm txoj kev zoo yog galvanization, qhov twg zinc txheej yog siv rau lem, ua hauj lwm raws li ib tug sacrificial txheej uas corrodes ua ntej thaum raug rau lub ntsiab. Cov txheej txheem no ua haujlwm zoo rau ob qho tib si tshiab thiab uas twb muaj lawm, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej hnyav.
Tsis tas li ntawd, siv cov ntaub ntawv tsis muaj corrosive zoo li stainless hlau hauv cov khoom siv railway yog qhov tseem ceeb. Stainless hlau tsis kam tiv thaiv corrosion thiab durability ua rau nws yog ib qho kev xaiv zoo heev rau kev ua kom muaj kev ntxhov siab tas li ntawm kev siv, ua rau muaj kev ntseeg tau ntawm kev tsheb ciav hlau tag nrho.
