Cov tshuaj kho dej ua lub luag haujlwm tseem ceeb hauv kev txuag dej thiab kev tiv thaiv ib puag ncig. Lawv txoj kev loj hlob yog tsom rau kev tsim kom muaj txiaj ntsig zoo, cov khoom tshwj xeeb uas haum rau cov yam ntxwv tshwj xeeb ntawm cov dej tau kho. Tsis hais txog ntawm daim ntawv thov, cov tshuaj kho dej yuav tsum xyuas kom meej tias cov dej kho tau ua tau raws li cov txheej txheem ib puag ncig uas lav tib neeg kev noj qab haus huv lossis tiv thaiv kev sib npaug ntawm ecological. Kev nyab xeeb ntawm cov dej kho nrog cov tshuaj kho dej, txawm tias tawm, rov ua dua, lossis siv los ua dej, yog qhov tseem ceeb. Tuam Tshoj cov khoom siv dej hauv ib tus neeg muaj tsawg heev, ua rau qhov sib npaug ntawm cov dej thiab xav tau qhov teeb meem tseem ceeb. Yog li ntawd, kev siv dej rov siv dua thiab cov dej khib nyiab rov siv dua yuav tsum tau siv cov tshuaj kho dej kom tsim nyog thiab siv cov thev naus laus zis kho mob.
Corrosion inhibitors yog cov tshuaj uas, thaum ntxiv rau hauv dej ntawm qhov tsim nyog thiab hauv cov ntaub ntawv tsim nyog, tuaj yeem tiv thaiv lossis ua kom qeeb ntawm corrosion ntawm cov ntaub ntawv hlau lossis khoom siv. Lawv yog cov yam ntxwv ntawm kev ua tau zoo, tsawg npaum li cas, thiab yooj yim ntawm kev siv. Muaj ntau ntau hom thiab ntau yam ntawm corrosion inhibitors. Raws li hom kev sib xyaw, lawv tuaj yeem muab faib ua inorganic thiab organic corrosion inhibitors. Raws li seb lawv inhibit anodic, cathodic, los yog ob qho tib si tshuaj tiv thaiv, lawv tuaj yeem raug cais raws li anodic, cathodic, lossis sib xyaw corrosion inhibitors. Corrosion inhibitors kuj tuaj yeem raug cais raws li cov txheej txheem ntawm kev tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau nto, xws li hom zaj duab xis passivation, nag lossis daus zaj duab xis hom, thiab adsorption zaj duab xis hom. Feem ntau siv passivation zaj duab xis hom corrosion inhibitors hauv kev kho dej muaj xws li chromates, nitrites, thiab molybdates; Feem ntau siv nag lossis daus zaj duab xis hom corrosion inhibitors suav nrog polyphosphates thiab zinc ntsev; thiab feem ntau siv adsorption zaj duab xis hom corrosion inhibitors muaj xws li cov organic amines.
