Kunokuba nzima ukufumana i-matt finishes nge-100% yezinto eziqinileyo ze-UV ezinyangekayo. Inqaku lakutshanje lichaza ii-agent ezahlukeneyo zokukhwelana kwaye lichaza ukuba zeziphi ezinye iinguqu zokubumba ezibalulekileyo.
Inqaku eliphambili lomcimbi wamva nje weEuropean Coatings Journal ichaza ubunzima bokufikelela kwi-matt 100% izinto eziqinileyo ze-UV-coatings. Ngokomzekelo, iimveliso zabathengi zibonakaliswe ukunxiba okuphindaphindiweyo kunye nokungcola kumjikelezo wobomi babo bonke, iingubo ezithambileyo zokuziva kufuneka zomelele kakhulu. Nangona kunjalo, ukulungelelanisa imvakalelo ethambileyo kunye nokumelana nokunxiba kungumngeni omkhulu. Kwakhona ubuninzi befilimu yokunciphisa ifilimu ngumqobo ekufezekiseni umphumo omuhle wokudibanisa.
Ababhali bavavanya imidibaniso eyahlukeneyo ye-silica matting agents kunye ne-UV reactive diluents kwaye bafunda irheology yabo kunye nenkangeleko. Uvavanyo lubonise ukuhluka okuphezulu kweziphumo, kuxhomekeke kuhlobo lwe-silica kunye ne-diluents.
Ukongezelela, ababhali bafunde i-ultrafine polyamide powders ebonisa ukusebenza kakuhle kwe-matting kunye nefuthe elincinci kwi-rheology kune-silicas. Njengokhetho lwesithathu, i-excimer pre-curing yaphandwa. Le teknoloji isetyenziswa kumacandelo amaninzi amashishini kunye nezicelo. I-Excimer imele i-“excimer dimer”, ngamanye amazwi i-dimer (umzekelo, i-Xe-Xe-, i-Kr-Cl gas) echwayitisayo ukuya kwimo yamandla ephezulu emva kokusetyenziswa kombane otshintshayo. Ngenxa yokuba ezi "dimers zovuyo" azinzanga ziyaqhekeka phakathi kwee-nanoseconds ezimbalwa, ziguqule amandla azo okuvuselela kwimitha yokukhanya. Le teknoloji ibonise iziphumo ezilungileyo, nangona kunjalo kuphela kwiimeko ezithile.
Nge-29 kaMeyi, uXavier Drujon, umbhali wenqaku uza kuchaza isifundo kunye neziphumo ngexesha lethu lenyanga le-webcast European Coatings Live. Ukuya kwi-webcast simahla ngokupheleleyo.
