Ukusetshenziswa
I-Photoinitiator TPO iyi-photoinitiator esebenza kahle kakhulu yohlobo lwe-free radical (1) emunca ububanzi obude be-wavelength. Ngenxa yobubanzi bayo obukhulu bokumunca, isiqongo sayo sokumunca esisebenzayo singama-350-400nm futhi imunca njalo kuze kufike ku-420nm. Isiqongo sayo sokumunca side kuneseziqali ezivamile. Ngemva kokukhanyisa, kungakhiqizwa ama-free radical amabili, i-benzoyl ne-phosphoryl, zombili ezingaqala i-polymerization. Ngakho-ke, ijubane lokuthwebula liyashesha. Iphinde ibe nomphumela wokuthwebula isithombe futhi ifanelekela ukuqiniswa kwefilimu ejiyile kanye nesici sokumbozwa okungaphuzi. Ine-volatility ephansi futhi ifanele izinhlelo ezisekelwe emanzini.
Isetshenziswa kakhulu ezinhlelweni ezimhlophe futhi ingasetshenziswa ezimbozweni ezingelapheki ze-UV, uyinki wokuphrinta, izinamathiseli ezilapheki ze-UV, izimbozo ze-optical fiber, ama-photoresists, amapuleti okuphrinta e-photopolymer, ama-resin e-stereolithography, izinto ezihlanganisiwe, izinto zokugcwalisa amazinyo, njll.
Njenge-photoinitiator, isetshenziswa kakhulu kuma-inki okunyathelisa isikrini, kuma-inki okunyathelisa i-lithographic, kuma-inki okunyathelisa i-flexographic, kanye nama-coatings okhuni. I-TPO ingalapheka ngokuphelele ezindaweni ezimhlophe noma ezine-titanium dioxide enombala ophezulu. Isetshenziswa kabanzi kuma-coatings ahlukahlukene. Ngenxa yezakhiwo zayo ezinhle zokumunca, ifaneleka kakhulu kuma-inki okunyathelisa isikrini, kuma-lithographic, kuma-inki okunyathelisa i-flexographic, kanye nama-coatings okhuni. I-coat ayiphenduki iphuzi, inomphumela ophansi we-post-polymerization, futhi ayishiyi nsalela. Ingasetshenziswa futhi kuma-coatings asobala, ikakhulukazi afanele imikhiqizo enezimfuneko zephunga eliphansi. Uma isetshenziswa yodwa kuma-polyester angagcwele aqukethe izinhlelo ze-styrene, inokusebenza kahle kakhulu kokuqala. Ezinhlelweni ze-acrylate, ikakhulukazi izinhlelo ezinemibala, ngokuvamile idinga ukusetshenziswa kanye nama-amine noma ama-acrylamides. Ngesikhathi esifanayo, ihlanganiswa nezinye i-photoinitiators ukuze kufezwe ukuphiliswa okuphelele kwesistimu. Ifaneleka kakhulu ekuphelisweni kwama-system aphuzi aphansi, amhlophe kanye nezendlalelo zefilimu ezijiyile. Uma i-photoinitiator TPO isetshenziswa kanye ne-MOB 240 noma i-CBP 393, ukusebenza kahle kokwelapha kungathuthukiswa. Iyisisombululo sokukhipha esingcono kakhulu samayunithi e-petroleum aromatic hydrocarbon futhi isetshenziswa futhi njenge-formylation reagent emkhakheni wamakhemikhali amahle.
Ukupakisha Nokuthumela
