He aha ka POE? Ka nānā 'ana i kona mau waiwai a me ka ho'ohana 'ana
ʻO POE (Polyolefin Elastomer) kahi mea polymer i hoʻohana nui ʻia i ka ʻoihana kemika i nā makahiki i hala. Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka piʻi ʻana o ka noi ʻoihana, ʻoi aku ka POE ma nā ʻano he nui ma muli o kāna mau waiwai kūʻokoʻa. Ma kēia ʻatikala, e kūkākūkā nui mākou i ke ʻano o ka POE, a me ka nānā ʻana i kāna mau waiwai, kaʻina hana a me nā wahi noi e kōkua i ka poʻe heluhelu e hoʻomaopopo pono i ka waiwai o kēia mea.
Na Waiwai Kumu o POE
He aha ka mea POE? Ma ke ʻano o ka hana kemika, ʻo POE kahi elastomer i hana ʻia mai ka copolymerization o ka ethylene me kahi monomer copolymerizing, maʻamau he α-olefin. ʻO kāna mau waiwai koʻikoʻi e pili ana i ka elasticity maikaʻi, haʻahaʻa haʻahaʻa, kiʻekiʻe ke aniani, a me ka maikaʻi o ka wā a me ke kūpaʻa haʻahaʻa haʻahaʻa. ʻO kēia mau waiwai ka mea e hiki ai i ka POE ke ʻoi aku i ka nui o nā noi, ʻo ia hoʻi i ka automotive, nā mea hoʻopili a me ka sheathing cable.
Ke Kaʻina Hana Hana POE
No ka hoʻomaopopo ʻana i ke ʻano o ka POE, pono e nānā i ke kaʻina hana i hana ʻia ai, ʻo ia ka mea maʻamau e ka metallocene catalyst polymerization. ʻO nā mea hoʻoheheʻe metallocene he mau mea hoʻoheheʻe ikaika loa e hiki ai ke hoʻomalu pono i ka puʻunaue kaumaha molekala o ka polymer a me ka hoʻopili ʻana o nā monomers copolymer. Loaʻa kēia kaʻina hana i ka hana maikaʻi loa a me nā waiwai huahana kūlike no kahi ākea o nā ʻano hana e like me ka injection, extrusion a me ka puhi ʻana.
Nā wahi noi nui o POE
Ke ʻike ʻoe i ke ʻano o ka POE, pono ka hoʻomaopopo ʻana i kāna mau wahi noi no ka hoʻomaopopo piha ʻana i ka mea. Ma muli o kona elasticity a me ka lōʻihi, hoʻohana ʻia ʻo POE i kahi ākea o nā noi kaʻa, ʻoi aku ka nui o nā sila kaʻa, nā bumper a me nā mea o loko. He wahi hoʻohana koʻikoʻi nō hoʻi nā mea hoʻopaʻa uea no POE. Me kona ʻano maikaʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa, hiki i ka POE ke hoʻolōʻihi i ke ola lawelawe o nā kaula.
POE vs. nā elastomers ʻē aʻe
No ka hoʻomaopopo maikaʻi ʻana i ke ʻano o ka POE, hiki iā mākou ke hoʻohālikelike iā ia me nā elastomers maʻamau e like me TPU (thermoplastic polyurethane) a me EPDM (ethylene propylene diene rubber), he haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka hana a me nā kumukūʻai haʻahaʻa. A hoʻohālikelike ʻia me EPDM, ʻoi aku ka maikaʻi o ka POE ma ke ʻano o ka hana haʻahaʻa haʻahaʻa a me ka ʻike. ʻO ka hopena, hoʻohana pinepine ʻia ʻo POE ma ke ʻano he mea ʻokoʻa e hoʻomaikaʻi i ka hana huahana a hoʻemi i nā kumukūʻai.
Hōʻuluʻulu manaʻo
He aha ka POE? ʻO ka maʻalahi, ʻo POE kahi mea elastomeric hana kiʻekiʻe me ka nui o nā noi. Mahalo i kāna mau waiwai kūikawā, e like me ka elasticity kiʻekiʻe, ka haʻahaʻa haʻahaʻa a me ke kaʻina hana maikaʻi loa, hōʻike ʻo POE i ka mana nui ma nā wahi he nui. Inā i loko o ka ʻoihana kaʻa, ʻoihana hoʻopihapiha, a i ʻole ka hana ʻana i ke kaula, wehe ʻo POE i nā mea hou i ka ʻepekema waiwai a me ka ʻenekinia.
Lana ka manaʻolana, ma o kēia ʻatikala, e ʻike maopopo ai ka poʻe heluhelu i ke ʻano o ka POE a me ke kumu e noho ai ia i kahi koʻikoʻi o ka ʻoihana kemika.
