Photoinitiator TPO powder 98% CAS 75980-60-8 TPOP
Photoinitiator TPO powder 98%I-CAS 75980-60-8TPOP
I-TPO yi-radical yasimahla esebenza kakhulu (1), i-optical absorption ephezulu esebenzayo yomqalisi kuluhlu olude lwamaza. Ngenxa yokuba inoluhlu olubanzi lokufunxa, incopho yokufunxa yi-350-400nm, ibangelwe kukufunxa malunga ne-420nm, incopho yayo yokufunxa kune-initiator eqhelekileyo inde kakhulu, ukukhanya kunokuvelisa i-benzoyl kunye ne-phosphoryl ezimbini.
Irediyo yasimahlaI-cals inokubangela i-polymerization, ngoko ke isantya sokunyanga ukukhanya, ikwane-photobleaching, ilungele ukugquma ifilimu eshinyeneyo kunye neempawu ezinzulu zokunyanga okutyheli kunye nokuguquguquka okuphantsi, emanzini. Le mveliso isetyenziselwa inkqubo emhlophe, ingasetyenziselwa iingubo zokunyanga ze-UV, ii-inki zokuprinta, i-adhesives, i-UV yokunyanga i-fiber optical coating, i-photoresist, i-photopolymerization plate, i-stereo lithographic resin, izinto ezidibeneyo, ukuzaliswa kwamazinyo njl .. Ukusetyenziswa kwale mveliso kufuneka isekelwe kwiziphumo ezichanekileyo zovavanyo, kuyacetyiswa ukuba ungeze inani le-0.5-4% w / w. Inokuqiniswa ngokupheleleyo kumphezulu omhlophe okanye ophezulu we-titanium dioxide pigment. Ingubo ayitshintshi, umphumo we-polymerization uphantsi, kwaye akukho ntsalela. Ingasetyenziselwa iingubo ezicacileyo, ngakumbi kwiimveliso zevumba eliphantsi. Isetyenziswe kwi-polyester engasetyenziswanga equkethe inkqubo ye-styrene, enokusebenza okuphezulu. Inkqubo ye-acrylate, ngakumbi inkqubo enemibala, idla ngokufuna ukusebenzisana ne-amine okanye i-acrylamide, kunye nezinye iikhompawundi zokuqalisa ukukhanya, ukunyanga ukufezekisa inkqubo yonyango epheleleyo ifaneleke ngokukodwa kwifilimu ephantsi etyheli, emhlophe kunye nengqindilili. I-inki yoshicilelo lwesikrini, i-inki yokushicilela ye-offset. Isixa esongezelelweyo esicetyiswayo se-0.5-3.0% (inkqubo enemibala), 0.3-2.0% (inkqubo ecacileyo.
