Nws tuaj yeem nyuaj kom tau matt tiav nrog 100% solids UV curable coatings. Ib tsab xov xwm tsis ntev los no piav txog cov neeg sawv cev sib txawv thiab piav qhia txog lwm yam kev hloov pauv uas tseem ceeb.
Cov ntawv tseem ceeb ntawm qhov teeb meem tshiab kawg ntawm European Coatings Journal piav qhia txog qhov nyuaj ntawm kev ua tiav matt 100% solids UV-coatings. Piv txwv li, cov neeg siv khoom tau raug rov qab hnav thiab cov kab mob sib kis thoob plaws hauv lawv lub neej, cov coatings mos-xws li yuav tsum ua kom ruaj khov. Txawm li cas los xij, ntsuas qhov muag muag nrog kev hnav tsis kam yog qhov nyuaj heev. Tsis tas li qhov ntau ntawm cov yeeb yaj kiab shrinkage yog ib qho teeb meem hauv kev ua tiav cov nyhuv matting zoo.
Cov kws sau ntawv tau sim ntau yam kev sib txuas ntawm silica matting agents thiab UV reactive diluents thiab kawm txog lawv cov rheology thiab tsos. Qhov kev ntsuam xyuas pom muaj qhov sib txawv ntawm cov txiaj ntsig, nyob ntawm seb hom silica thiab diluents.
Tsis tas li ntawd, cov kws sau ntawv tau kawm ultrafine polyamide hmoov uas pom tias muaj kev ua haujlwm siab matting thiab tsis tshua muaj txiaj ntsig ntawm rheology dua li cov silicas. Raws li qhov kev xaiv thib peb excimer ua ntej kho tau raug tshawb xyuas. Cov thev naus laus zis no tau siv ntau hauv kev lag luam thiab kev siv. Excimer stands rau "zoo siab dimer", nyob rau hauv lwm yam lus, ib tug dimer (xws li Xe-Xe-, Kr-Cl gas) uas zoo siab rau lub zog siab dua tom qab daim ntawv thov ntawm ib tug alternating voltage. Vim tias cov "dimers zoo siab" tsis ruaj khov lawv tawg nyob rau hauv ob peb nanoseconds, hloov lawv lub zog excitation rau optical hluav taws xob. Cov thev naus laus zis no tau pom cov txiaj ntsig zoo, txawm li cas los xij tsuas yog hauv qee kis.
Thaum Lub Tsib Hlis 29, Xavier Drujon, tus sau tsab xov xwm yuav piav qhia txog qhov kev kawm thiab cov txiaj ntsig thaum peb lub hli webcast European Coatings Live. Mus koom lub webcast yog dawb kiag li.
