OMBB, chemically hu uaMethyl 2-benzoylbenzoate (CAS No. 606-28-0), yog hom II photoinitiator dav siv nyob rau hauv UV-cov txheej txheem kho, inks, adhesives, thiab varnishes. Nws nyob ze - cov yam ntxwv tsis muaj ntxhiab ua rau nws txaus nyiam tshwj xeeb rau cov ntawv thov uas tsis muaj ntxhiab tsw yog qhov tseem ceeb ntawm kev tsim qauv.
OMBB ua haujlwm los ntawm kev nqus UV lub teeb thiab tsim cov hom reactive uas pib lub polymerization ntawm unsaturated oligomers thiab monomers, xws li acrylate-raws li resins. Nyob rau hauv ntau formulations, OMBB yog siv ua ke nrog atertiary amine synergisttxhawm rau txhim kho photoinitiation efficiency thiab kho kev ua haujlwm.
Qhov kev pom zoo noj yog nyob ntawm qhov system resin, zaj duab xis tuab, xim xim, UV teeb, thiab xav tau ceev ceev. Raws li qhov pib dav dav, qee qhov kev lag luam OMBB qib pom zoo kwv yees li2-5% ntawm qhov hnyav, ua raws li kev ua kom zoo dua los ntawm kev sim kuaj.
OMBB tuaj yeem muab tso rau hauv ntau hom UV- kho tshuab, suav nrogwood coatings, yas coatings, hlau coatings, luam ntawv inks, overprint varnishes, adhesives, thiab cov khoom siv hluav taws xob. Nws kuj tseem siv rau hauv UV number case thiab kua roj vanish rau ntim daim ntaub ntawv.
Rau cov txiaj ntsig zoo tshaj plaws, cov tsim qauv yuav tsum xav txog OMBB kev sib raug zoo nrog cov resin thiab lwm yam photoinitiators, nrog rau kev siv lub teeb, curing wavelength, txheej thickness, thiab pigment loading. Kev sib xyaw ua ke ntawm photoinitiators qee zaum tuaj yeem muab qhov sib npaug ntau dua thiab dhau los ntawm -kev ua haujlwm kho.
Thaum xaiv OMBB, zoo ib yam purity, tsis tshua muaj volatile cov ntsiab lus, txhim khu kev qha batch - mus rau -batch zoo, thiab tsim nyog cov ntaub ntawv yog ib qho tseem ceeb rau industrial UV- daim ntaub ntawv kho.
