Hoʻohana
ʻO ka Photoinitiator TPO kahi photoinitiator ʻano radical manuahi (1) kūpono loa e omo ana i kahi lōʻihi o ka nalu. Ma muli o kona laulā omo ʻana, ʻo kona piko omo kūpono he 350-400nm a omo mau ia a hiki i kahi o 420nm. ʻOi aku ka lōʻihi o kona piko omo ma mua o nā mea hoʻomaka maʻamau. Ma hope o ka hoʻomālamalama ʻana, hiki ke hana ʻia ʻelua mau radical manuahi, benzoyl a me phosphoryl, hiki i nā mea ʻelua ke hoʻomaka i ka polymerization. No laila, wikiwiki ka wikiwiki o ka photocuring. Loaʻa iā ia kahi hopena photobleaching a kūpono no ka hoʻōla hohonu ʻana o ka ʻili mānoanoa a me ke ʻano o ka uhi ʻole melemele. He haʻahaʻa ka volatility a kūpono no nā ʻōnaehana wai.
Hoʻohana nui ʻia ia i nā ʻōnaehana keʻokeʻo a hiki ke hoʻopili ʻia i nā uhi UV-curable, nā ʻīnika paʻi, nā mea hoʻopili UV-curable, nā uhi fiber optical, nā photoresists, nā papa paʻi photopolymer, nā resins stereolithography, nā mea i hui pū ʻia, nā mea hoʻopiha niho, a pēlā aku.
Ma ke ʻano he photoinitiator, hoʻohana nui ʻia ia i nā ʻīnika paʻi pale, nā ʻīnika paʻi lithographic, nā ʻīnika paʻi flexographic, a me nā uhi lāʻau. Hiki ke hoʻōla piha ʻia ʻo TPO ma nā ʻili keʻokeʻo a i ʻole nā ʻili titanium dioxide kiʻekiʻe. Hoʻohana nui ʻia ia i nā uhi like ʻole. Ma muli o kona mau waiwai omo maikaʻi loa, kūpono loa ia no nā ʻīnika paʻi pale, ka paʻi lithographic, nā ʻīnika paʻi flexographic, a me nā uhi lāʻau. ʻAʻole e melemele ka uhi, he hopena post-polymerization haʻahaʻa, a ʻaʻohe koena e waiho. Hiki ke hoʻohana ʻia i nā uhi aniani, kūpono loa no nā huahana me nā koi ʻala haʻahaʻa. Ke hoʻohana wale ʻia i loko o nā polyesters unsaturated i loaʻa nā ʻōnaehana styrene, he kiʻekiʻe loa ka hoʻomaka ʻana. No nā ʻōnaehana acrylate, ʻoi aku hoʻi nā ʻōnaehana kala, pono e hoʻohana pinepine ʻia me nā amines a i ʻole acrylamides. I ka manawa like, ua hui pū ʻia me nā photoinitiator ʻē aʻe e hoʻokō i ka hoʻōla piha ʻana o ka ʻōnaehana. He kūpono loa ia no ka hoʻōla ʻana i nā ʻōnaehana melemele haʻahaʻa, keʻokeʻo a me nā papa kiʻiʻoniʻoni mānoanoa. Ke hoʻohana ʻia ka photoinitiator TPO me MOB 240 a i ʻole CBP 393, hiki ke hoʻomaikaʻi ʻia ka pono o ka hoʻōla ʻana. ʻO ia ka mea hoʻoheheʻe hoʻokaʻawale maikaʻi loa no nā ʻāpana hydrocarbon aromatic petroleum a hoʻohana ʻia hoʻi ma ke ʻano he reagent formylation ma ke kahua o nā kemika maikaʻi.
ʻŌpala a me ka Hoʻouna ʻana
20KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
