Umsebenzi
I-Photoinitiator TPO iyi-pilinitiator esebenza kahle kakhulu ye-radical (1) yohlobo oluthathayo e-wavelength ende. Ngenxa yebanga layo lokumuncwa kakhulu, inani layo elisebenzayo lokumunca alona lingu-350-400nm futhi lithatha ngokuqhubekayo kuze kube ngu-420nm. Inani layo lokutholwa lide kunalona labaqali abajwayelekile. Ngemuva kokukhanyisa, ama-radicals amabili wamahhala, i-benzoyl ne-phosphoryl, angenziwa, zombili ezingaqala ukwenza i-polymerization. Ngakho-ke, ijubane le-photocung liyashesha. Iphinde ibe nomphumela we-Photobleaching futhi ilungele ukuphulukisa okujulile kwefilimu kanye nesimo sokuhlanganiswa okuphuzi okuphuzi. Inokuguquguquka okuphansi futhi ilungele amasistimu asuselwa emanzini.
Isetshenziswa kakhulu ezinhlelweni ezimhlophe futhi ingafakwa kwizimbobo ze-UV eziguqukayo, izithasiselo zokuphrinta, ukunamathela kwe-UV evukelayo, amapuleti wokuphrinta we-optical, amapuleti we-Photopolymer, izinto zokugcwalisa amazinyo, njll.
Njenge-perinititor, isetshenziswa ikakhulukazi kuma-inks wokuphrinta wesikrini, ama-inks wokuphrinta we-lithographic, ama-inks wokuphrinta we-flagographic, nezinkuni zezinkuni. I-TPO ingalapheka ngokuphelele ku-White noma i-Titanium Dioxide Pignment Surfaces. Kusetshenziswa kabanzi egqoke imishini ehlukahlukene. Ngenxa yezakhiwo zayo zokumuncwa okuhle kakhulu, zilungele ikakhulukazi ama-inks wokuphrinta wesikrini, ukuphrinta kwe-lithographic, inkki yokuphrinta ye-flezographic, nezinkuni zezinkuni. Ukuhlanganiswa akuphenduki okuphuzi, kunomphumela ophansi we-polymerization, futhi kungashiyi izinsalela. Ingasetshenziswa futhi ezitsheni ezisobala, ikakhulukazi imikhiqizo enezidingo eziphansi zephunga. Lapho isetshenziswa yedwa kuma-polyesters angafakwanga aqukethe amasistimu we-styrene, inokusebenza kahle kokuqala okuphezulu kakhulu. Ngezinhlelo ze-acrylate, ikakhulukazi amasistimu anemibala, kuvame ukusetshenziselwa ukusetshenziselwa ukuhlanganiswa noma ama-acrylamides. Ngasikhathi sinye, kuhlanganiswe namanye amakhambi ukuthola ukwelashwa okuphelele kohlelo. Ilungele ikakhulukazi ukwelashwa kwama-aphuzi aphuzi, amhlophe kanye nezinhlaka zefilimu eziwugqinsi. Lapho i-Photoinitiator TPO isetshenziswa ngokuhlanganiswa nesixuku sama-240 noma i-CBP 393, ukusebenza kahle kokwelapha kungathuthukiswa. Kuyindlela engcono kakhulu ye-solvent yama-petroleum aromatic hydrocarbon amayunithi futhi isetshenziswa futhi njenge-reagent yendlela emkhakheni wamakhemikhali amahle.
Ukupakisha nokuthumela
I-20KG / DRUM noma njengezidingo zamakhasimende.
Kungokwezimpahla ezijwayelekile futhi kungahambisa ngo-Ocean nomoya
Gcina futhi ugcine
I-Shelf Life: Inyanga engama-24 kusukela ngosuku lokwenziwa ekuphaketheni kwasekuqaleni okungavunyelwe okugcinwe endaweni epholile eyomile ngaphandle kokukhanya kwelanga, amanzi.
I-Warehouse evutha umoya, ukomisa okushisa okuphansi, okuhlukaniswe nama-oxidants, ama-acid.
