Zitha kukhala zovuta kupeza zomaliza za matt ndi 100% zolimba zokutira zochiritsira za UV.Nkhani yaposachedwa ikufotokoza zotengera zosiyanasiyana zokwerera ndikufotokozera zomwe zosintha zina ndizofunikira.
Nkhani yayikulu yaposachedwa kwambiri ya European Coatings Journal ikufotokoza zovuta zakupeza matt 100 % zolimba zokutira UV.Mwachitsanzo, zinthu zomwe ogula amagula zimatha kuvala mobwerezabwereza komanso zowononga nthawi yonse ya moyo wawo, zokutira zofewa ziyenera kukhala zolimba kwambiri.Komabe, kugwirizanitsa kumverera kofewa ndi kukana kuvala ndizovuta kwambiri.Komanso kuchuluka kwa kuchepa kwa filimu ndizolepheretsa kukwaniritsa zotsatira zabwino za matting.
Olembawo anayesa mitundu yosiyanasiyana ya ma silika matting agents ndi UV reactive diluents ndikuphunzira ma rheology ndi mawonekedwe awo.Chiyesocho chinawonetsa kusiyana kwakukulu kwa zotsatira, kutengera mtundu wa silika ndi diluents.
Kuonjezera apo, olembawo adaphunzira ufa wa ultrafine polyamide womwe umasonyeza bwino kwambiri matting ndipo unali ndi zotsatira zochepa pa rheology kusiyana ndi silika.Monga njira yachitatu excimer pre-curing anafufuzidwa.Tekinoloje iyi imagwiritsidwa ntchito m'magawo ambiri azamakampani komanso ntchito.Excimer imayimira "chisangalalo cha dimer", mwa kuyankhula kwina dimer (monga Xe-Xe-, Kr-Cl gas) yomwe imakhala yokondwa kukhala yamphamvu kwambiri potsatira kugwiritsa ntchito mphamvu yamagetsi yosinthira.Chifukwa "ma dimer okondwa" awa ndi osakhazikika amawonongeka mkati mwa nanoseconds pang'ono, kutembenuza mphamvu yawo yosangalatsa kukhala cheza cha kuwala.Tekinoloje iyi idawonetsa zotsatira zabwino, komabe nthawi zina.
Pa Meyi 29, Xavier Drujon, yemwe adalemba nkhaniyi afotokoza za kafukufukuyu ndi zotsatira zake pa tsamba lathu lapaintaneti la European Coatings Live.Kupezeka pawebusaiti ndi kwaulere.
