Road Marking Paint vs. Road Marking Coating: Piav qhia qhov txawv ntawm qhov tseem ceeb
Txoj kev npav yog qhov tseem ceeb rau kev taw qhia kev tsheb thiab txhim kho txoj kev nyab xeeb. Thaum cov ntsiab lus "xim" thiab "txheej txheem" qee zaum siv sib hloov, lawv xa mus rau cov chav sib txawv ntawm cov ntaub ntawv nrog cov khoom sib txawv thiab kev siv.
Txoj kev kos duab pleev xim feem ntau yog cov khoom ua kua uas dries los ua ib zaj duab xis nyias. Feem ntau hom yog dej-raws li acrylics thiab hnyav-raws li alkyds. Cov xim no paub txog lawv lub sijhawm ziab sai, yooj yim ntawm daim ntawv thov, thiab tus nqi pib qis dua. Txawm li cas los xij, lawv muab lub neej ua haujlwm luv dua, feem ntau yuav tsum tau rov ua dua txhua 1-2 xyoos vim hnav los ntawm kev khiav tsheb thiab huab cua.
Txoj kev npav txheej, ntawm qhov tod tes, yog lub kaus rau cov khoom siv ruaj khov. Cov no suav nrog cov thermoplastics, cov yas siv txias (CAP), thiab epoxy. Piv txwv li, thermoplastics yog siv kub (180-220 ° C) thiab tsim ib txheej tuab, ruaj khov thaum txias. Lawv paub txog kev ua neej zoo, kav ntev li 3-6 xyoo, thiab zoo dua retroreflectivity vim cov iav hlaws dai, tab sis lawv xav tau cov cuab yeej tshwj xeeb thiab sawv cev rau kev nqis peev ntau dua.
Kev xaiv ntawm cov xim thiab txheej yog nyob ntawm ntau yam. Xim yog haum rau txoj kev hauv nroog, chaw nres tsheb, thiab cov chaw tsheb qis qis uas muaj txiaj ntsig zoo thiab daim ntawv thov ceev yog qhov tseem ceeb. Cov txheej txheem txheej txheem zoo li cov thermoplastics yog qhov nyiam rau thaj chaw tsheb loj xws li kev loj thiab kev sib tshuam, qhov chaw ua haujlwm ntev thiab kev pom mus ntev yog qhov tseem ceeb rau kev nyab xeeb.
Hauv cov ntsiab lus, txoj kev kos xim xim yog ib hom txheej txheej muaj nuj nqis rau nws txoj kev lag luam thiab kev yooj yim, thaum txoj kev kos cov txheej txheem suav nrog ntau yam kev ua tau zoo, cov khoom siv ruaj khov tsim rau kev siv mus sij hawm ntev ntawm txoj kev xav tau.
