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

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

TPO-Lno nā ʻīnika paʻi pale UV, ka paʻi offset UV a me nā ʻīnika flexo UV;

TPO-Lvarnish ʻala ʻole, pena pepa, pā paʻi pale mālamalama, stereolithography.

ʻO ka mea hoʻomaka kiʻi TPO-L he mea hoʻomaka UV wai no kahi resin i loaʻa ka acrylic a me kahi polyester unsaturated i loaʻa ka styrene. No ka mea he wai ia, ʻo ka photoinitiator TPO-L he "maʻalahi ke hoʻohui" i nā ʻano hana āpau. No ka mea TPO-L Hoʻopili i nā nalu lōʻihi i ka spectrum UV, hoʻōla piha hoʻi ia i nā uhi me ka titanium dioxide a me nā uhi pālahalaha me ka titanium dioxide. ʻO ke ʻano o ka uhi i loaʻa pēlā ua hōʻike ʻia e ka melemele haʻahaʻa loa.

Ma muli o kona haʻahaʻa haʻalulu, ʻo ka photoinitiator TPO-L kūpono no ka hana ʻana i nā ʻano hana ʻala haʻahaʻa. ʻO ka photoinitiator TPO-L ua hoʻohui ʻia ma kahi lakio o 0.3 a 5%, a ua loaʻa ka ʻāpana polymerizable i loko o nā pena a me nā ʻīnika paʻi.

ʻO ka mea hoʻomaka kiʻi TPO-L Hoʻohui pinepine ʻia me nā photoinitiators ʻē aʻe e like me ka photoinitiator 184, photoinitiator 1173, photoinitiator TZT a i ʻole benzophenone. Hoʻoulu kēia i ka hoʻōla ʻana o ka ʻili. No ka mea TPO-L Hoʻopili i ka UV nalu lōʻihi, he mea maʻalahi ia i ka lā me nā huahana i loaʻa iā ia. ʻO ka hopena, pono e kāpae i ka mālamalama nona ka nalu ma lalo o 500 nm i ka wā e mālama ai a me ka lawelawe ʻana (e laʻa, ua uhi ʻia nā puka makani a me nā kukui me kahi ʻili melemele).
