Environmental Factors pab txhawb rau Rail Spike Corrosion
Kev xeb ntawm cov ntsia hlau spikes yog cov txheej txheem nyuaj cuam tshuam los ntawm ntau yam ib puag ncig. Thaum muab tso rau ntawm txoj kev nrog cov neeg pw tsaug zog, cov spikes raug rau cov huab cua rau lub sijhawm ntev. Tau ntau xyoo ntawm kev siv, lawv ntsib cov dej nag tsis tu ncua, cov neeg caij tsheb ciav hlau emissions, dej khib nyiab, thiab tshuaj lom neeg thiab cov zaub mov los ntawm cov tsheb ciav hlau thauj khoom. Kev hloov pauv huab cua, hloov pauv kub, thiab hnyav sab nraud ib puag ncig ua rau muaj kev xeb, tshwj xeeb tshaj yog cuam tshuam rau cov xov sab sauv thiab puag ncig platform tom qab anchoring.
Hauv qhov chaw ua haujlwm niaj hnub, cov spikes feem ntau yog qias neeg los ntawm:
Cov neeg caij tsheb ciav hlau Emissions: Cov quav, tso zis, thiab cov dej ntxuav tawm ntawm cov neeg caij tsheb ciav hlau muaj ntau yam organic teeb meem, kab mob, kab mob, sulfur-muaj, thiab chlorine-muaj cov tebchaw, thiab inorganic ntsev (calcium, hlau, magnesium). Cov ntsiab lus no tsim ib qho kev daws teeb meem ntawm electrolyte ib puag ncig uas tsim nyog rau kev sib tsoo corrosion.
Atmospheric Sulfur: Sulfur thiab sulfide nyob rau hauv cov huab cua, nrog rau cov sulfur anchoring agents, tuaj yeem yooj yim corrode spikes. Ib puag ncig huab cua hauv cheeb tsam: Cov kua qaub gases (SO2, ammonia), thiab cov dej-soluble kua hais tawm tawm los ntawm cov nroj tsuag tshuaj nyob ze ntawm txoj kab, txuas mus rau spikes, ua rau corrosion.
Acid Precipitation: Tsis ntev los no ib puag ncig muaj kuab paug tau ua rau acidic nag lossis daus, ua rau corrosion.
Freight Train Emissions: Cov khoom siv tshuaj lom neeg thiab cov zaub mov, xws li cov pa roj carbon monoxide, tawg los ntawm cov tsheb ciav hlau thauj khoom, kuj ua lub luag haujlwm hauv corrosion.
