Ke kūlana noi a me ka manaʻolana o ka ʻenehana hoʻohūhū ma ke kāʻei uila kaʻa

I nā makahiki i hala iho nei, ua ulu wikiwiki ka ʻoihana kaʻa o Kina, a ua hoʻohana nui ʻia ka polyurethane, kekahi o nā mea polymer, i nā ʻāpana kaʻa.

I loko o ka automotive uea harness huahana, ka hana nui o ka uea harness alakaʻi groove e hōʻoia i ka uea harness ua palekana palekana a paʻa i ke kino i loko o ka liʻiliʻi a irregular huna wahi o ke kaʻa.Ma nā wahi me kahi haʻahaʻa haʻahaʻa e koi ana i ka wela, e like me ka ʻāpana o ka poʻe kaʻa, e hoʻohana i ka plastic kiʻekiʻe-molecular-weight i mea no ke alakaʻi harness.Ma nā wahi paʻakikī e like me ke kiʻekiʻe o ka wela a me ka haʻalulu, e like me nā keʻena mīkini, nā mea me ke kūpaʻa wela kiʻekiʻe, e like me ke aniani fiber reinforced nylon, pono e koho ʻia.
Hoʻomalu ʻia nā ʻenekini maʻamau e nā paipu corrugated, a ʻo nā mea hoʻohana i hoʻopau ʻia e kēia hoʻolālā he mau hiʻohiʻona o ke kumu kūʻai haʻahaʻa, hana maʻalahi a maʻalahi.Eia nō naʻe, ʻilihune ka hiki ʻana o ka anti-corrosion a me ka anti-fouling o ka uea i hoʻopau ʻia, ʻoi aku ka lepo, ka aila, a me nā mea ʻē aʻe hiki ke komo maʻalahi i loko o ke kaula uea.
He alakaʻi maikaʻi a maʻalahi ka hoʻokomo ʻana i ke kaula uea i hoʻopau ʻia e ka polyurethane foam molding.Pono ka mea hana e hahai i ke kuhikuhi a me ke ala ma hope o ka loaʻa ʻana o ke kaula uea, a hiki ke hoʻokomo ʻia i hoʻokahi ʻanuʻu, ʻaʻole maʻalahi ke hana hewa.ʻO ke kaula uila i hana ʻia me ka polyurethane he nui nā hiʻohiʻona i ʻoi aku ka maikaʻi ma mua o nā wili uila maʻamau, e like me ka pale ʻana i ka aila, ka ikaika o ka lepo lepo, a ʻaʻohe walaʻau ma hope o ka hoʻokomo ʻia ʻana o ke kaula uila, a hiki ke hana ʻia i nā ʻano like ʻole e like me ke ākea o ke kino.

Eia nō naʻe, no ka mea, ʻo ka ʻoihana uea i hana ʻia i kēia mea pono e hoʻolilo nui i nā lako paʻa i ka wā mua, ʻaʻole i hoʻohana ka nui o nā mea hana wili i kēia ʻano, a he mau kaʻa kiʻekiʻe wale nō e like me Mercedes-Benz a me Audi engine wiring harnesses. hoʻohana ʻia.Eia nō naʻe, ke helu ʻia ka nui o ke kauoha a paʻa, inā e helu ʻia ke kumukūʻai a me ka maikaʻi, a laila ʻoi aku ka maikaʻi o ka hoʻokūkū.

Outlook
Ke hoʻohālikelikeʻia me ke kaʻina hana hoʻoheheʻe maʻamau, RIM polyurethane nā mea a me nā kaʻina hana i nā mea maikaʻi o ka haʻahaʻa haʻahaʻa o ka ikehu, ke kaumaha māmā, ka hana maʻalahi, ka liʻiliʻi liʻiliʻi a me nā kumukūʻai hana, a me nā mea'ē aʻe. ʻoi aku ka paʻakikī.Pono e hoʻokomo ʻia nā ʻāpana ʻē aʻe ma ke ākea, no laila ʻoi aku ka ʻokoʻa o ka wahi i waiho ʻia no ke kaula uwea.ʻOi aku ka palena o ka mold injection maʻamau i kēia ʻano, ʻoiai ʻoi aku ka maʻalahi o ka hoʻolālā polyurethane mold.
ʻO ka Reinforced Reaction Injection Molding (RRIM) he ʻano hou o ka ʻenehana hoʻoheheʻe ʻana i ka ʻenehana e hana ana i nā huahana me nā waiwai mechanical ʻoi aku ka maikaʻi ma o ka hoʻokomo ʻana i nā mea hoʻopihapiha fibrous e like me nā fibers aniani i loko o ka mold preheated.
ʻO ka hoʻohana ʻana i nā mea hana a me nā lako polyurethane e hana i ka hana noiʻi ma ka ʻenehana polyurethane hiki ke hoʻonui i ka hana hana o nā mea a hoʻomaikaʻi i ka hana o nā mea.I ka wā e hiki mai ana, pono e hoʻokomo hohonu ʻia ka ʻenehana i ka hana ʻana i nā ʻāpana alakaʻi alakaʻi uea kaʻa.Hiki i nā ʻoihana ke hoʻokō i ka pahuhopu e hōʻemi i nā kumukūʻai a hoʻomaikaʻi i ka hoʻokūkū mākeke.
