Hoʻohana
2,4,6-Trimethylbenzoyldiphenylphosphine oxide isHoʻohana nui ʻia no 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 pigment titanium dioxide keʻokeʻo a me ke kiʻekiʻe. Hoʻohana nui ʻia i nā uhi like ʻole, ma muli o kāna hana hoʻopili maikaʻi loa, kūpono loa ia no ka ʻīnika paʻi pale, ka paʻi pālahalaha, ka ʻīnika paʻi flexographic, a me nā uhi lāʻau. ʻAʻole melemele ka uhi, haʻahaʻa ka hopena polymerization ma hope, a ʻaʻohe koena. Hiki ke hoʻohana ʻia no 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 ka styrene, he kiʻekiʻe kona pono hoʻomaka. No nā ʻōnaehana acrylic ester, ʻoi aku hoʻi nā ʻōnaehana kala, pono lākou e hoʻohana pinepine ʻia me nā amines a i ʻole acrylamides, a hui pū ʻia me nā photoinitiators ʻē aʻe e hoʻokō i ka hoʻōla piha ʻana o ka ʻōnaehana. He kūpono loa lākou no ka hoʻōla ʻana i ka melemele haʻahaʻa, nā ʻōnaehana keʻokeʻo, a me nā papa kiʻiʻoniʻoni mānoanoa. ʻO ka hui pū ʻana o ka photoinitiator TPO a me MOB240 a i ʻole CBP393 hiki ke hoʻomaikaʻi i ka pono hoʻōla. ʻO ia ka mea hoʻoheheʻe hoʻokaʻawale maikaʻi loa no nā mea kanu hydrocarbon ʻala petroleum a hoʻohana ʻia hoʻi ma ke ʻano he reagent formylation ma ke kahua o nā kemika maikaʻi.
ʻO ia ka mea hoʻoheheʻe hoʻoheheʻe maikaʻi loa no nā mea kanu hydrocarbon ʻala petroleum; ʻO ka hui pū ʻana o N-formylmorpholine a me morpholine (1:1) ka mea hoʻoheheʻe hoʻoheheʻe no ka ʻāpana methyl ethyl ketone. Hoʻohana ʻia hoʻi ia ma ke ʻano he reagent formylation ma ke kahua o nā kemika maikaʻi. Hoʻohana nui ʻia no ka ʻīnika paʻi pale, ka ʻīnika paʻi planographic, ka ʻīnika paʻi flexographic, nā uhi lāʻau, nā uhi hoʻōla UV, ka ʻīnika paʻi, nā mea hoʻopili hoʻōla UV, nā uhi fiber optical, a pēlā aku.

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.
