I loko o nā ʻoihana he nui, mai ke kūkulu ʻana a hiki i ka hana ʻana i nā lako, ʻo ka polyurethane foam ka mea i hōʻike ʻia i kahi hana mana o ka kemika hou. He mea maʻalahi kēia mea kupanaha a he mea hoʻokani kiʻekiʻe, e hoʻohuli i ko mākou honua a puni. ʻO kahi nānā hohonu i nā nuances o ka polyurethane foam no kāna kaʻina hana, hoʻomau ka hoʻoikaika ʻana i nā waiwai insulation a me ka laulā o nā hoʻohana ʻoihana a me nā mea ʻoluʻolu maikaʻi i hana ʻia. ʻO ka hohonu a mākou e hele ai, ʻoi aku ka maopopo o ka hohonu o kahi polyurethane foam maoli.
Aia ma ka puʻuwai o kēlā me kēia huahana polyurethane foam ʻoʻoleʻa kahi hopena kemika i hoʻonohonoho pono ʻia i kapa ʻia he polymerization. He hui ia o ʻelua mau mea nui: diisocyanates a me polyols. He mau polymers thermosetting i hoʻopaʻa kemika i nā isocyanates, a loaʻa i loko o lākou nā molekole me nā ʻāpana hana hou i hoʻopau ʻia e nā hui hydroxyl. Hoʻohui ʻia kēia mau mea i kahi mahana a me ke kaomi e hana ai i ka huʻa i hiki ke hoʻoheheʻe ʻia i nā ʻano like ʻole, nā ikaika, nā maʻalahi. Eia kekahi, ʻo nā catalysts, nā mea puhi puhi a me nā mea hoʻohui ke kuleana no ka hoʻoponopono hou ʻana i kēia mau waiwai me ka ʻole o nā ʻūhā hāmama (hoʻohana maikaʻi ʻia e like me nā mea hoʻoheheʻe leo) a i ʻole nā huhū kelepona paʻa me kona waiwai insulating maikaʻi loa ʻaʻole hiki ke hiki.
Ma muli o ka hopena o ke kaiapuni e pili ana i ka hoʻoili ʻana i nā huahana foam maʻamau, aia nā mea noiʻi a me nā mea hana i kahi misionari no ka hoʻomohala ʻana i nā huahana polyurethane ʻōmaʻomaʻo. Hoʻohana ia i nā polyols i hoʻokumu ʻia i ka bio e hiki mai ana mai nā kumu hou e like me ka soybeans, ka aila castor a i ʻole nā hue PET recycled. ʻO kēia mau mea hoʻololi hoʻomau e hoʻemi nui i ka hilinaʻi wahie fossil pū kekahi a hui pū kekahi i nā kiʻekiʻe hana. Eia hou, ua hiki i ka hoʻohana ʻana i nā mea hoʻololi haʻahaʻa-global-warming-potential (GWP) no ka HCFC-141b a me HFCs 245fa a me 123. A inā ʻaʻole lawa ka ʻōmaʻomaʻo iā ʻoe, aia ka hana hou a me ka hoʻomohala ʻana i nā polyurethanes biodegradable pū kekahi.
ʻO ka hiki ke insulation thermal ka waiwai kūʻokoʻa o ka polyurethane foam, kahi e hoʻohanohano ai. ʻO ka hapa nui kēia ma muli o ka paʻa paʻa ʻana o nā ʻano mea paʻa i hoʻopaʻa ʻia i ka ea a hoʻopaʻa ʻia i ka wai e hoʻemi nui i ka neʻe ʻana i nā wela pono ʻole. ʻO ka hopena, hoʻemi kēia i ka nui o nā emmissions mai ka hoʻomehana a me ka hoʻoluʻu ʻana, e hana ana i nā hale ikaika loa no ka uku liʻiliʻi. Eia hou, hiki i ka foam ke hoʻopiha piha i nā āpau a me nā hakahaka maikaʻi loa no laila e kōkua i ka hōʻemi ʻana i ka infiltration o ka ea e alakaʻi ana i ka hoʻomaikaʻi ʻana i kāu pono holoʻokoʻa. ʻO ka polyurethane foam insulation kahi mea nui no ka mālama ʻana i nā huahana palaho i ka wā o ka lawe ʻana i nā logistic kaulahao e hoʻomaikaʻi ai i ka palekana o ka meaʻai a me ka hōʻemi ʻana i ka ʻōpala.
Mai ka hāʻawi ʻana i ka hōʻoluʻolu i nā lako a hiki i ka mālama ʻana i ka insulation i loko o nā ʻāpana refrigeration, ʻike ʻia ka polyurethane foam no kāna versatility. Maikaʻi kona lawe ʻia ʻana no ka māmā māmā i ka ʻoihana kaʻa, kahi e hāʻawi ai i nā pōmaikaʻi ʻelua a me ka hoʻohaʻahaʻa leo me ka hāʻawi ʻole ʻana i ke kaumaha-ʻaʻole pono i nā mea māmā. I ka mālama ola kino, hoʻohana ʻia ka polyurethane foam i nā prosthetics no kona ʻano like ʻole o ka ʻiʻo maoli a me nā moena o ka haukapila e hoʻomaikaʻi i kāna mau hiʻohiʻona hypoallergenic a me nā anti-bacterial. Me kāna mau waiwai hoʻohāhā i nā mea haʻuki, hoʻonui ia i ka palekana i ka wā e komo ai nā mea haʻuki i nā hana kino. Ma ka ʻoihana hana hoʻi, hāʻawi ka polyurethane foam i ka nui o ka cushioning a me ka hōʻoluʻolu i nā lole āu e neʻe nei i ka helu me ka ʻole e kaumaha i ka lōʻihi no ka hana hou.
ʻO ka paʻakikī o ka hana ʻana i nā huahana, hiki iā Ronghe ke hoʻohana i ka waiwai maka kiʻekiʻe e hoʻoponopono pololei i nā ana kūikawā a me ke ʻano o ka mea e hoʻokō ai i kāu mau pono. Loaʻa iā mākou nā makahiki o ka ʻike i ka lawelawe ʻana i nā mākeke lehulehu, me ka hoʻopilikino ʻana i ka huahana polyurethane foam, ka hoʻopaʻa ʻana i ke kaula e hoʻopilikino ana i nā huahana plastik, nā ʻōpala i hana ʻia me ka laʻa. Manaʻo mākou e hana pū me ʻoe.
Ua hoʻokumu ʻia ʻo Qinghe Ronghe Rubber Products Co. Ltd. i ka makahiki 2015. He paʻa ʻo ia i mea kūikawā i ka hana ʻana i nā huahana plastik a me nā ʻāpana pahu. Hoʻokuʻu aku i ʻEulopa ʻAmelika a me ʻApelika a me Asia Hikina Hema.
ʻO nā huahana PU a i ʻole nā huahana ʻē aʻe e hoʻomaikaʻi i ka huahana polyurethane foam o kā lākou mau mea paʻa a paʻa. a i ʻole nā ʻāpana palaki āu e makemake ai a i ʻole ke ʻano o ke kaiapuni āu e noho ai.
Mālama mākou i nā huahana polyurethane foam i kēlā me kēia kaʻina hana e hōʻoia i loaʻa iā ʻoe nā koi lako kūpono e pili ana i ka manawa, ka maikaʻi a me ka nui. ʻO kā mākou manaʻo nui i ka hāʻawi ʻana i nā hopena maikaʻi a hoʻoponopono ʻia no nā huahana PU foam me nā huahana rubber, nā huahana plastik e hoʻokō i kāu mau koi ponoʻī.
