Ukwelapha Okusebenza Kakhulu, Ukuphuzi Okuphansi – 2,4,6-Trimethylbenzoyldiphenylphosphine oxide, Okuhola Inkathi Entsha Yokwelapha Nge-UV

Ukubuka Konke Komkhiqizo

I-2,4,6-Trimethylbenzoyldiphenylphosphine oxide iyi-photoinitiator esebenza kahle kakhulu yohlobo lwe-Type I radical. Njengoba imunca ububanzi bayo, ishesha ukuphiliswa, kanye nezakhiwo zayo eziphuzi kancane, isibe yisinqumo esifanele sezinhlelo zokupholisa i-UV.
Izinzuzo Eziyinhloko
Ukwelapha Okusheshayo Kakhulu Nokungena Okujulile: Ukuphakama kokumunca kusuka ku-350-400nm, kufinyelela ku-420nm. Kufanelekela amafilimu aqinile kanye nezinhlelo ezimhlophe eziqukethe i-TiO₂, okuqinisekisa ukwelapha okuphelele.
Ukumelana Nokuphuzi: Igcina ukucaca okuhlala isikhathi eside, ilungele ama-varnish, ukupakisha okuphezulu, kanye nemikhiqizo ezwela umbala.
Iphunga Eliphansi Nokuphepha: Ukuguquguquka okuphansi kuhlangabezana nezidingo eziqinile zokupakisha ukudla nezinto zokwelapha.
Ukuhambisana Okuhle Kakhulu: Kusebenza kahle ngama-acrylates, ama-polyester angagcwalisiwe, njll., futhi kungahlanganiswa nezinye izinto zokuqala (isb., ama-α-hydroxy ketones) ukuze kuthuthukiswe ukusebenza kahle.
Izicelo Ezihlukahlukene
Ukwembozwa: Ukwembozwa ngokhuni, insimbi, ipulasitiki, kanye ne-optical fiber ukuze kulungiswe ngokushesha nangokulinganayo.
Uyinki: Ukuphrinta kwe-inkjet yesikrini, i-lithographic, i-flexographic, kanye ne-UV ukuze kuthuthukiswe ikhwalithi kanye nesivinini.
Izinto zokunamathisela: Ukubopha okunamandla kakhulu kwepulasitiki, ingilazi, kanye nezinsimbi.
