CAS 84434-11-7 Photoinitiator TPO-L i nā uhi ho'ōla UV

TPO-L fa i ʻole ka pena melemele haʻahaʻa, puaʻa keʻokeʻo UV;

TPO-Lno nā ʻīnika paʻi pale UV, ka paʻi ʻana o UV a me nā inika flexo UV;

TPO-Lvarnish ʻala haʻahaʻa, pena ma ka pepa, paʻi paʻi māmā, stereolithography.

ʻO ka mea hoʻomaka kiʻiTPO-L he mea hoʻomaka UV wai no ka resin a me ka polyester unsaturated i loko o ka styrene. No ka mea he wai, ka photoinitiatorTPO-L he "maʻalahi ke hoʻohui" i nā mea hoʻopuka āpau. No ka meaTPO-L hoʻopaʻa i nā hawewe lōʻihi i ka spectrum UV, hoʻōla piha hoʻi i nā uhi me ka titanium dioxide a me nā uhi pālahalaha me ka titanium dioxide. ʻO ka uhi i loaʻa pēlā ua ʻike ʻia e ka melemele haʻahaʻa loa.

Ma muli o kona haʻahaʻa volatility, ka photoinitiatorTPO-L kūpono ia no ka hana ʻana i nā mea ʻala haʻahaʻa. ʻO ka mea hoʻomaka kiʻiTPO-Lua hoʻohui ʻia ma kahi ratio o 0.3 a 5%, a aia ka hapa polymerizable i loko o nā pena a me nā inika paʻi.

ʻO ka mea hoʻomaka kiʻiTPO-L Hoʻohui pinepine ʻia me nā photoinitiator ʻē aʻe e like me ka photoinitiator 184, photoinitiator 1173, photoinitiator TZT a i ʻole benzophenone. Hoʻoikaika kēia i ka mālama ʻana i ka ʻili. No ka meaTPO-L hoʻopaʻa i ka UV hawewe lōʻihi, ʻoluʻolu ia i ka lā me nā huahana i loaʻa iā ia. ʻO ka hopena, pono e hoʻokaʻawale i ka mālamalama me ka lōʻihi o ka nalu ma lalo o 500 nm i ka wā o ka mālama ʻana a me ka mālama ʻana (e laʻa, uhi ʻia nā puka makani a me nā kukui me kahi kiʻi melemele).
