Yuav ua li cas xaiv cov txheej txheem kev kho kom haum rau cov kab hlau?

Xaiv cov kev kho sab nrauv kom raug rauRail SpikesKoom nrog txiav txim siab corrosion tsis kam, nqi, thiab ib puag ncig app. Rau qhov qis - tus nqi xaiv, dawb (roj) lossis blacking + roj yuav siv tau kev tiv thaiv ib ntus. Rau zoo corrosion tsis kam, electro {{4 4}} galvanizing yog ib qho kev tiv thaiv zoo li ntev tau siv, tab sis nws kim dua. Rau qhov kev daws tshwj xeeb ntau dua, cov tsho tshaj zoo li dacromet muab cov kev tsis muaj corrosion tsis muaj yam tsis muaj hydrogen embrittlement, tab sis lawv yog tus nqi.

Cov kev kho kho mob los ntawm tus nqi thiab corrosion tsis kam

Dawb (oiled):Qhov kev xaiv pheej yig tshaj, muab kev tiv thaiv ib ntus rau kev xeb.

Blackening + roj:Qhov nrov thiab qis {- txoj kev siv tus nqi feem ntau siv rau cov ceev ceev.

Electro - galvanizing:Tus nqi - Txoj kev ua tau zoo nrog kev ua haujlwm corrosion zoo.

Dacromet Txheej:Muaj kev tiv thaiv corrosion zoo heev thiab high - kub ruaj khov, tab sis yog kim dua li galvanizing.

Kub - dip galvanizing (HDg):Muab cov tshuaj tiv thaiv corrosion zoo tshaj plaws rau ntev - tsis siv, tab sis yog kim dua electro {} galvanizing.

Yam los txiav txim siab

Nqi:Pob nyiaj siv rau txoj haujlwm yuav txiav txim siab txoj kev kho kom haum tshaj plaws. Cov roj av dawb yog cov pheej yig tshaj, thaum cov txheej txheem tshwj xeeb yog qhov kim tshaj plaws.

Ib puag ncig cov xwm txheej:Xav txog ib puag ncig uas cov spikes yuav raug siv. Kev siv hnyav lossis xeb cov teeb meem yuav tsum muaj kev tiv thaiv zoo li kub - dacromet txheej.

Kev Pab Lub Neej:Rau ntev - lus thov, kev kho mob uas muaj kev tiv thaiv corrosion zoo li kub- dip galvanizing yog pom zoo tshaj li qhov yooj yim roj.

Daim Ntawv Thov Tshwj Xeeb:Cov kev cai tshwj xeeb, xws li tsis kam mus rau hydrogen embrittlement lossis qhov kub siab, yuav ua rau lwm txoj kev kho kom tsim nyog.

Kev tsheb ciav hlau loj heev

Ntsia Hlau Ntaus

Thaum xub thawj qhia nyob rau hauv 1860 hauv Fab Kis, tom qab ntawd tusNtsia Hlau NtausTsis ntev los ua cov khoom siv kev tsheb ciav hlau ntau hauv tebchaws European. Cov ntsia hlau hluav taws xob, tseem hu ua kev tsheb ntsia hlau, yog lub hau hlau loj siv los ua kom nrawm dua ib qho kev tsheb nqaj hlau ob qho. Dhau li, nws tseem siv los kho khi daim hlau lossis kho rau hauv lub qhov laj nyob hauv lub sleeper. Owing rau cov kev kho kom zoo dua thiab cov yam ntxwv uas tuaj yeem ua ke nrog cov tshuab raj hlav hlav Nyob rau hauv lub neej sib txawv, kev tsheb nqaj hlau sib tw yog tsuas yog siv hauv qee cov ntawv thov kev tsheb ciav hlau hnyav thiab hauv cov ua si vaj teb, chaw ua si nyob thiab lwm yam.

Aub spikes

Aub ntsia hlau lojyog lwm qhov tseem ceeb ntawm kev tsheb ciav hlau spikes. Vim hais tias ntawm ob lub haus ntawm ob sab, tus dev loj zoo li tus dev lub taub hau. Ib yam li cov ntsia hlau spikes, tus dev spikes muaj qhov ntev zoo sib xws. Tab sis raws li lub taub hau, nws muaj qhov taw qhia lub taub hau.
