mea hoʻomaka kiʻi

ʻO Photoinitiator, i ʻike ʻia ʻo photosensitizer a i ʻole photocuring agent, he ʻano mea hana synthetic e hiki ke hoʻopaʻa i ka ikehu o kekahi mau nalu i ka ʻāpana ultraviolet (250 ~ 420nm) a i ʻole ka ʻāina ʻike ʻia (400 ~ 800nm) a hana i nā radical manuahi a me nā cations.
No ka hoʻomaka ʻana i ka polymerization monomer o nā pūhui hoʻōla i hoʻopili ʻia.

Loaʻa i ka molekele hoʻomaka ka hiki ke hoʻoheheʻe māmā i ka ʻāpana ultraviolet (250-400 nm) a i ʻole ka ʻāpana ʻike ʻia (400-800 nm).Ma hope o ka lawe ʻana i ka ikehu māmā a pololei ʻole paha, e hoʻololi ka molekele hoʻomaka mai ka mokuʻāina a i ka mokuʻāina hoʻohiwahiwa, a laila lele i ka mokuʻāina triplet hauʻoli ma o ka intersystem.
Ma hope o ka hoʻoulu ʻia ʻana o ka singlelet a i ʻole ka triplet states i ka monomolecular a i ʻole bimolecular chemical reactions, hana ʻia nā ʻāpana ikaika e hiki ai ke hoʻomaka i ka polymerization o nā monomers, a hiki i kēia mau ʻāpana ikaika ke lilo i nā radical manuahi, cations, anions, etc.
Wahi a nā ʻano hana hoʻomaka ʻokoʻa, hiki ke hoʻokaʻawale ʻia nā photoinitiators i nā photoinitiators polymerization free radical a me nā photoinitiators cationic, i waena o nā photoinitiators polymerization free radical i hoʻohana nui ʻia.
