Keeb Kwm ntawm UV-Kho Polyurethane Dispersions
Xyoo 1990, kev siv cov anionic polyurethane dispersions uas muaj acrylate pawg txuas rau polymer hauv kev lag luam tau pib siv rau hauv kev siv hauv kev lag luam.1 Ntau yam ntawm cov ntawv thov no yog nyob rau hauv kev ntim khoom, kua mem, thiab cov txheej ntoo. Daim duab 1 qhia txog cov qauv dav dav ntawm UV-curable PUD, qhia txog yuav ua li cas cov khoom siv txheej no tau tsim.
DUAB 1 | Cov tshuaj polyurethane acrylate ua haujlwm dav dav.3
Raws li pom hauv Daim Duab 1, cov khoom siv polyurethane uas kho tau los ntawm UV (UV-curable PUDs), yog ua los ntawm cov khoom siv ib txwm siv los ua cov khoom siv polyurethane. Aliphatic diisocyanates raug tshuaj nrog cov esters, diols, hydrophilization pawg, thiab cov saw hlau txuas uas siv los ua cov khoom siv polyurethane.2 Qhov txawv yog qhov ntxiv ntawm acrylate functional ester, epoxy, lossis ethers uas koom ua ke rau hauv cov kauj ruam ua ntej-polymer thaum ua cov khoom siv dispersion. Kev xaiv cov ntaub ntawv siv los ua cov khoom siv, nrog rau cov qauv polymer thiab kev ua tiav, qhia txog kev ua tau zoo thiab cov yam ntxwv ntawm PUD. Cov kev xaiv no hauv cov ntaub ntawv raw thiab kev ua tiav yuav ua rau cov PUDs uas kho tau los ntawm UV uas tuaj yeem tsim tsis yog zaj duab xis, nrog rau cov uas tsim zaj duab xis.3 Cov hom kev tsim zaj duab xis, lossis cov hom kev ziab, yog lub ntsiab lus ntawm tsab xov xwm no.
Kev tsim cov yeeb yaj kiab, lossis ziab raws li nws feem ntau hu ua, yuav ua rau cov yeeb yaj kiab sib sau ua ke uas qhuav rau qhov kov ua ntej UV kho. Vim tias cov neeg thov xav txwv tsis pub muaj kev sib kis ntawm cov txheej txheem vim muaj cov khoom me me, nrog rau qhov xav tau kev nrawm hauv lawv cov txheej txheem ntau lawm, cov no feem ntau raug ziab hauv qhov cub ua ib feem ntawm cov txheej txheem txuas ntxiv ua ntej UV kho. Daim duab 2 qhia txog cov txheej txheem ziab thiab kho ib txwm muaj ntawm UV-kho tau PUD.
