Ua hana ʻo Shanghai Deborn Co., Ltd. i nā mea hoʻohui kemika mai ka makahiki 2013, ʻo ia ka hui ma Pudong New District o Shanghai.
Hana ʻo Deborn e hoʻolako i nā kemika a me nā hoʻonā no nā ʻoihana lole, nā palakiko, nā uhi ʻana, nā pena, nā mea uila, nā lāʻau lapaʻau, ka home a me ka mālama pilikino.
No ka ʻohana o ka benzophenone i pani ʻia ʻo BP-2 e pale aku ana i ka radiation ultraviolet.
Loaʻa iā BP-2 ka omo kiʻekiʻe ma nā wahi UV-A a me UV-B, no laila ua hoʻohana nui ʻia ʻo ia ma ke ʻano he kānana UV i nā ʻoihana hoʻonani a me nā kemika kūikawā.
He kaumaha molekala nui, ʻaʻole e lele, kū'ē i ka unuhi ʻia; hana maʻalahi ʻia.
ʻO kahi mea hoʻoheheʻe UV benzotriazole hiki ke kāohi i nā hopena hōʻino oxidation, pale i nā mea fiber, a hoʻomaikaʻi i ka pae huahana textile; he hanauna hou kēia o nā mea hoʻoheheʻe UV me ka ʻenehana patent a lanakila i ka palapala hōʻoia huahana koʻikoʻi o ka mokuʻāina 2007, hiki i ka pae honua.
He kūpono kēia huahana i Polyolefine, Polyvinyl chloride, aniani organik a me nā mea ʻē aʻe. ʻO ka lōʻihi o ka nalu omo kiʻekiʻe loa he 270-400nm.
He mea hoʻopaʻa kukui kiʻekiʻe kēia huahana, a hoʻohana nui ʻia i ka plastic a me nā mea olaola ʻē aʻe. Loaʻa iā ia ka hiki ke omo i ka radiation ultraviolet a haʻahaʻa ka volatility.
Ma ke ʻano he mea hoʻomoʻa ultraviolet, loaʻa ia iā PVC, polystyrene a me Polyolefine etc. ʻO ka laulā nalu hoʻomoʻa kiʻekiʻe loa he 280-340nm. ʻO ka hoʻohana maʻamau: 0.1-0.5% no ka mea lahilahi, 0.05-0.2% no ka mea mānoanoa.
ʻO Tridecyl phosphite ka antioxidant phosphite ʻaʻohe phenol, aloha i ke kaiapuni. He mea hoʻopaʻa wela phosphite wai kūpono ia no ka polyolefin, polyuranthane, coating, ABS, lubricant etc. Hiki ke hoʻohana ʻia i nā noi PVC paʻa a me ka plasticized e hāʻawi i nā kala ʻoi aku ka mālamalama, kūlike a hoʻomaikaʻi i ke kala mua a me ka maopopo.
Pili i ka ABS, PVC, polyurethane, nā uhi, nā mea hoʻopili a pēlā aku.
ʻAʻole haumia ka antioxidant thermal-oxidation. kūpono no SBS, TPR, TPS, PS, SBR, BR, PVC, PE, PP, ABS a me nā elastomers rubber ʻē aʻe, me ka hana kūpaʻa thermal oxidative kiʻekiʻe, ka hana ʻana, ʻaʻole hoʻololi i nā kala i ke kaʻina hana, kūpono loa no ka mea hoʻopaʻa kala ʻole. ʻAʻohe hopena maikaʻi ʻole i ke kala o ka huahana; hoʻohana nui ʻia i nā huahana keʻokeʻo a me chromic.
ʻO ka Antioxidant P-EPQ he Antioxidant lua kiʻekiʻe me ka pale ʻana i ka mahana kiʻekiʻe.
He kūpono i nā ʻōnaehana PP, PA, PU, PC, EVA, PBT, ABS a me nā polymers ʻē aʻe, ʻoi aku hoʻi no nā ʻōnaehana plastik ʻenekinia PC, PET, PA, PBT, PS, PP, PE-LLD, EVA.
Hoʻohana ʻia ia i nā polylefins (e laʻa me Polyethylene, polypropylene etc.), PU, ABS a me ke kaula kamaʻilio etc. He antioxidant phenolic i pale ʻia e ka steric a me ka mea hoʻopau metala. Mālama ia i nā polymers mai ka hoʻohaʻahaʻa oxidative a me ka hoʻohaʻahaʻa metala catalyzed i ka wā o ka hana ʻana a ma nā noi hope. Hāʻawi pū kēia antioxidant i nā waiwai hoʻopaʻa wela lōʻihi.
ʻO ka Antioxidant HP136 ka hopena kūikawā no ka hana extrusion o Polypropylene ma ke ana wela kiʻekiʻe i nā lako extrusion. Hiki iā ia ke pale pono i ka melemele a pale i ka mea ma o ka hoʻopaʻa ʻana i ke kalapona a me ka alkyl radical i maʻalahi ke hana ʻia i ke kūlana hypoxic.
Hana ia ma ke ʻano he synergist maikaʻi me ka phenolic antioxidant AO1010 a me ka Phosphite Ester Antioxidant AO168.
ʻO ka Antioxidant DTDTP kahi antioxidant thioester lua no nā polymers organik e hoʻopau a hoʻopau i nā hydroperoxides i hoʻokumu ʻia e ka auto-oxidation o nā polymers. He antioxidant ia no nā plastics a me nā rubbers a he mea hoʻopaʻa pono no nā polyolefins, ʻoiai ʻo PP a me HDPE. Hoʻohana nui ʻia ia ma ABS, HIPS PE, PP, polyamides, a me polyesters.
