Tshaj tawm rau 05-07-2018Nrog rau txoj kev loj hlob sai ntawm cov khoom siv niaj hnub no, ntau thiab ntau cov khoom siv high-tech tau muab tso rau hauv kev siv.Kev siv tshuab ua kom yooj yim rau peb lub neej.Dacromet yuav tsum nkag siab los ntawm ntau tus neeg.
Dacromet muaj cov ntawv thov hauv ntau qhov kev lag luam.Dacromet technology yog tam sim no ua ke nrog ntau txheej txheej.Nws tuaj yeem ua tau zoo heev los tiv thaiv corrosion ntawm qhov chaw ntawm cov khoom.Yog li vim li cas nws thiaj li khaws tau cov khoom?
Dacromet txheej, zoo li yog matt silver-grey, tsim los ntawm cov hlau zoo heev zinc, txhuas thiab chromate Cheebtsam.Tom qab lub workpiece deoiled thiab tua blasted, Dacromet yog dip-coated.
Dacromet kua yog ib hom dej kho cov kua dej.Cov khoom siv hlau yog dip-coated los yog tshuaj tsuag-txhaj tshuaj nyob rau hauv cov dej-raws li kev daws teeb meem, ces lawv yog solidified nyob rau hauv lub cub tawg thiab ci ntawm li 300 ° C. los ua ib tug inorganic txheej ntawm zinc, txhuas thiab chromium.Thaum kho, cov dej noo nyob rau hauv txheej zaj duab xis, organic (cellulose) thiab lwm yam volatile Cheebtsam volatilize, thiab oxidizing cov cuab yeej ntawm high-valent chromium ntsev nyob rau hauv Dacromet niam cawv ua rau lub electrode tej zaum yuav muaj ib tug loj tus nqi tsis zoo.
Tom qab aluminium foil slurry thiab hlau matrix, chromium ntsev compound ntawm Fe, Zn, thiab Al yog tsim.Vim tias txheej zaj duab xis tau txais ncaj qha tom qab lub substrate, cov txheej txheem tiv thaiv corrosion yog qhov ntom ntom.Nyob rau hauv ib puag ncig corrosive, cov txheej yuav tsim ntau lub roj teeb tseem ceeb, uas yog, ntau qhov tsis zoo Al thiab Zn ntsev yuav raug tshem tawm ua ntej kom txog thaum lawv muaj peev xwm corrode lub substrate nws tus kheej tom qab noj.
