Ukusetyenziswa
I-Photoinitiator TPO yi-photoinitiator esebenza kakuhle kakhulu yohlobo lwe-free radical (1) efunxa kuluhlu olude lwe-wavelength. Ngenxa yoluhlu lwayo olubanzi kakhulu lokufunxa, incochoyi yayo esebenzayo yokufunxa yi-350-400nm kwaye ifunxa rhoqo ukuya kuthi ga kwi-420nm. Incochoyi yayo yokufunxa inde kuneye-initiators eqhelekileyo. Emva kokukhanyisa, ii-free radicals ezimbini, i-benzoyl kunye ne-phosphoryl, zinokuveliswa, zombini ezinokuthi ziqalise i-polymerization. Ke ngoko, isantya sokufota siyakhawuleza. Ikwanayo nefuthe lokufota kwaye ifanelekile kwi-deep film thick kunye neempawu ze-non-yellowing coating. Ine-volatility ephantsi kwaye ifanelekile kwiinkqubo ezisekelwe emanzini.
Isetyenziswa kakhulu kwiinkqubo ezimhlophe kwaye ingafakwa kwiingubo ezinyangwa yi-UV, ii-inki zokuprinta, izincamathelisi ezinyangwa yi-UV, iingubo zefayibha ye-optical, ii-photoresists, iipleyiti zokuprinta ze-photopolymer, ii-resin ze-stereolithography, izinto ezidityanisiweyo, izinto zokuzalisa amazinyo, njl.njl.
Njenge-photoinitiator, isetyenziswa kakhulu kwii-inki zokuprinta isikrini, ii-inki zokuprinta ze-lithographic, ii-inki zokuprinta ze-flexographic, kunye neengubo zomthi. I-TPO inokunyangeka ngokupheleleyo kwiindawo ezimhlophe okanye ezine-titanium dioxide eninzi. Isetyenziswa kakhulu kwiingubo ezahlukeneyo. Ngenxa yeempawu zayo ezintle zokufunxa, ifanelekile ngakumbi kwii-inki zokuprinta isikrini, ii-lithographic printing, ii-inki zokuprinta ze-flexographic, kunye neengubo zomthi. Ingubo ayijiki ibe tyheli, inefuthe eliphantsi emva kwe-polymerization, kwaye ayishiyi ntsalela. Ingasetyenziswa nakwiingubo ezibonakalayo, ngakumbi ezifanelekileyo kwiimveliso ezineemfuno eziphantsi zevumba. Xa isetyenziswa yodwa kwii-polyester ezingagcwaliyo ezineenkqubo ze-styrene, inokusebenza okuphezulu kakhulu kokuqala. Kwiinkqubo ze-acrylate, ngakumbi iinkqubo ezinemibala, idla ngokufuna ukusetyenziswa kunye nee-amines okanye ii-acrylamides. Kwangaxeshanye, ixutywe nezinye ii-photoinitiators ukuze kufezekiswe ukuphiliswa ngokupheleleyo kwenkqubo. Ifanelekile ngakumbi ekuphelisweni kweenkqubo ezityheli eziphantsi, ezimhlophe kunye neengqimba zefilimu ezityebileyo. Xa i-TPO ye-photoinitiator isetyenziswa kunye ne-MOB 240 okanye i-CBP 393, ukusebenza kakuhle kokuphilisa kunokuphuculwa. Yeyona solvent ilungileyo yokukhutshelwa kweeyunithi ze-hydrocarbon ze-petroleum aromatic kwaye ikwasetyenziswa njenge-reagent ye-formylation kwicandelo leekhemikhali ezintle.
