Raws li "hloov" ntawm photocuring thev naus laus zis, qhov sib xyaw ntawm photoinitiators ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov tshuaj tiv thaiv. Cov khoom siv tseem ceeb tau muab faib ua ob pawg:
Aromatic ketones: xws li benzophenone thiab thioxanthrone, uas tsim cov dawb radicals los ntawm absorbing ultraviolet lub teeb.
Catonic ketones: xws li iodonium ntsev thiab thioxanthrone, uas tso Lewis acids nyob rau hauv lub teeb irradiation.
Co-initiators: Amine compounds (xws li methyldiethanolamine) feem ntau yog siv los ua cov khoom sib xyaw ua ke.
Cov tshuaj tiv thaiv kab mob ntawm cov khoom siv raw: Cov khoom sib txawv ntawm cov khoom siv raw zoo li tshuaj "formulas," ua rau cov teebmeem tshwj xeeb:
Wavelength txuam: Thioxanthrones yog haum rau 365nm ultraviolet lub teeb, thaum camphorquinone yog matched nrog pom lub teeb.
Cov yam ntxwv solubility: Qee cov khoom siv raw yuav tsum tau ua ke nrog acrylate monomers los txhim kho kev sib raug zoo.
Kev nyab xeeb: Niaj hnub nimno ib puag ncig tus phooj ywg raw cov ntaub ntawv yog maj mam hloov cov tshuaj chlorine ib txwm muaj - muaj cov tshuaj.
Kev xaiv cov khoom siv raw hauv kev lag luam: Hauv kev tsim khoom tiag tiag, kev xaiv raw khoom yuav tsum xav txog ntau yam:
Printing inks nyiam tsawg - ntxhiab thiol co- pib.
Kev ntim khoom siv hluav taws xob yuav tsum muaj -purity iodonium ntsev raw cov ntaub ntawv.
3D luam ntawv photosensitive resins feem ntau siv ob -cov txheej txheem pib.
Ntoo coatings feem ntau siv hloov kho benzophenone nrog kev nkag mus zoo.
