Txoj kev ntawm Railway Track Rust Protection
Ua raws li cov txheej txheem no yog qhov tseem ceeb rau kev tiv thaiv kev tsheb ciav hlau tiv thaiv xeb, ua kom cov neeg caij tsheb muaj kev nyab xeeb thiab ua kom lub neej ntev. Cia peb pom lawv ua ke.
- Lub cev Barrier Method
Nqe lus piav qhia:Tsim ib qho kev thaiv ntawm qhov khiav ntawm cov hlau nto thiab cov khoom corrosive siv cov ntaub ntawv xws li cov xim los yog txheej.
Piv txwv:Epoxy coatings, enamel xim, zinc txheej.
Kev tiv thaiv:Tiv thaiv kom tsis txhob ya raws, oxygen, thiab cov khoom corrosive kom ncav cuag cov hlau nto.
- Txoj kev tiv thaiv Cathodic
Nqe lus piav qhia:Siv cov txheej txheem electrochemical los tiv thaiv corrosion los ntawm kev qhia txog hluav taws xob tam sim no.
Daim ntawv thov:Ua rau txoj kev tsheb ciav hlau cathodic (tsis zoo) txheeb ze rau ib qho anode nyob ze (zoo).
Kev ua tau zoo:Ua tau zoo thiab siv dav hauv kev lag luam railway.
- Kev Siv Tshuaj
Nqe lus piav qhia:Siv tshuaj lom neeg los tiv thaiv xeb.
Piv txwv:Rust inhibitors (piv txwv li, polyurethane, cov khoom siv acrylic) tsim cov txheej txheem tiv thaiv, thiab xeb hloov pauv (xws li tannic acid, phosphoric acid) chemically hloov xeb.
Kev tiv thaiv:Inhibitors tiv thaiv xeb, converters hloov xeb mus rau hauv ib tug non-reactive compound.
- Txoj Kev Electrochemical
Nqe lus piav qhia:Qhia cov hluav taws xob tam sim no los tiv thaiv corrosion, zoo ib yam li cathodic tiv thaiv.
Daim ntawv thov:Ua rau txoj kev tsheb ciav hlau anodic (zoo) txheeb ze rau ib qho cathode nyob ze (tsis zoo).
Kev tu:Yuav tsum tau saib xyuas tas li thiab kev saib xyuas kom muaj txiaj ntsig zoo.
