1. Electropated txheej
Cov txheej txheem hluav taws xob yog ib qho ntawm feem ntau dav siv kev tiv thaiv corrosion tiv thaiv kev daws teeb meem. Electroplating suav nrog kev tso cai siv hlau tso rau saum npoo ntawm lub caij nplooj ntoo hlav los ua zaj duab xis passive nyob rau hauv tus ntawm sab nraud lub zog. Cov ntaub ntawv txheej electropated muaj xws li zinc, npib tsib xee, thiab chromium, uas tiv thaiv oxidation thiab corrosion ntawm lub caij nplooj ntoo hlav. Txawm li cas los xij, cov txheej txheem hluav taws xob muaj qee qhov kev txwv thiab tsuas yog tsim nyog rau qhov chaw tsis muaj huab cua nyob hauv qhov chaw ib puag ncig.
2. Thermal txau txheej txheej
Thermal txau txheej ci yog ib qho kev ua tau zoo corrosion tiv thaiv kev daws teeb meem rau kev quav. Hauv cov qauv no, hmoov nplej lossis cov xov hlau ua los ntawm cov khoom sib txawv tau txau ntawm lub caij nplooj ntoo hlav los ntawm cov nplaim hluav taws, lossis lwm yam kev sib xyaw los tsim cov txheej txheem xeb. Thermal txau cov tsho muaj zog muaj cov muaj zog corrosion tsis kam, zoo heev los tiv thaiv corrosion, thiab zoo tshaj plaws coj tsis kam. Cov txheej txheej no yog qhov haum rau kev siv hauv ib puag ncig nrog cov muaj zog acids, hauv paus muaj zog, thiab lwm yam mob uas muaj zog.
3. Cov organic txheej txheem
Cov txheej txheem organic yog ib qho siv kev tiv thaiv corrosion hauv caij nplooj hlav, muab cov txheej tiv thaiv rau lub caij nplooj ntoo hlav. Piv txwv ntawm cov txheej txheem organic muaj xws li ci enamel, txau pleev xim pleev xim, thiab xeb-resist hlau txheej. Qhov zoo ntawm cov txheej txheem organic yog qhov yooj yim ntawm daim ntawv thov, tus nqi qis, thiab cov zoo corrosion tsis kam. Cov txheej txheem organic yog qhov zoo rau springs hauv tsawg-kub thiab qis-corrosion ib puag ncig.
Hauv cov ntsiab lus, xaiv qhov tsim nyog corrosion tiv thaiv txheej rau springs tuaj yeem txuas ntxiv rau lawv lub neej thiab txo cov khoom siv txij nkawm. Yog li ntawd, cov chaw tsim khoom lag luam hauv kev teeb tsa kev lag luam yuav tsum xaiv cov txheej txheej raws lawv cov cai ib puag ncig.
