Hiki ke paʻakikī ke loaʻa i ka pau ʻana me ka 100% solids UV curable coatings. Hōʻike ʻia kahi ʻatikala hou i nā ʻāpana moena ʻē aʻe a wehewehe i nā mea koʻikoʻi o ka hoʻohālikelike ʻana.
ʻO ka ʻatikala nui o ka pukana hou loa o ka European Coatings Journal e wehewehe i ka paʻakikī o ka loaʻa ʻana o ka matt 100% solids UV-coatings. No ka laʻana, ʻike ʻia nā huahana mea kūʻai aku i ka ʻaʻahu a me nā mea haumia i ko lākou pōʻaiapuni o ke ola, pono e paʻa loa nā pale palupalu. Eia naʻe, ʻo ka hoʻohālikelike ʻana i ka manaʻo palupalu me ke kūpaʻa ʻaʻahu he paʻakikī nui. ʻO ka nui o ka emi ʻana o ke kiʻiʻoniʻoni he mea keakea i ka loaʻa ʻana o ka hopena moena maikaʻi.
Ua hoʻāʻo nā mea kākau i nā hui like ʻole o ka silica matting agents a me nā diluent reactive UV a nānā i kā lākou rheology a me ke ʻano. Ua hōʻike ka hoʻāʻo i kahi ʻano kiʻekiʻe o nā hopena, ma muli o ke ʻano silica a me nā diluent.
Hoʻohui, ua aʻo nā mea kākau i nā pauka polyamide ultrafine i hōʻike i ka matting kiʻekiʻe a me ka liʻiliʻi o ka hopena i ka rheology ma mua o ka silicas. E like me ke kolu koho excimer pre-curing ua noiʻi. Hoʻohana ʻia kēia ʻenehana i nā ʻāpana ʻoihana a me nā noi. ʻO ka Excimer ke kū nei no "dimer hauʻoli", ʻo ia hoʻi, he dimer (e laʻa me Xe-Xe-, Kr-Cl gas) i hauʻoli i kahi kūlana ikehu kiʻekiʻe aʻe ma hope o ka hoʻohana ʻana i kahi volena hoʻololi. Ma muli o ka paʻa ʻole o kēia mau "dimer hauʻoli" e hoʻokaʻawale lākou i loko o kekahi mau nanoseconds, e hoʻohuli ana i ko lākou ikehu hoʻoulu i ka radiation optical. Ua hōʻike kēia ʻenehana i nā hopena maikaʻi, akā i kekahi mau hihia.
Ma Mei 29, ʻo Xavier Drujon, ka mea kākau o ka ʻatikala e wehewehe i ke aʻo ʻana a me nā hopena i ka wā o kā mākou pūnaewele pūnaewele European Coatings Live. ʻAʻole uku ʻia ka hele ʻana i ka hoʻolaha pūnaewele.
