Hoʻohana mākou i nā kuki e hoʻomaikaʻi i kou ʻike.Ma ka hoʻomau ʻana i kēia pūnaewele, ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki.ʻIke hou aku.
Hoʻohana maʻamau ʻia ka polyurethane foam (PU) i ke kūkulu ʻana no nā kumu like ʻole, akā me ka pana ʻana i ka zero emissions, ke hoʻonui nei ka nānā ʻana i nā mea pili i ke kaiapuni.He mea koʻikoʻi ka hoʻomaikaʻi ʻana i ko lākou inoa ʻōmaʻomaʻo.
ʻO ka polyurethane foam he polymer i loaʻa nā ʻāpana monomer organik i hoʻopili ʻia e ka urethane.ʻO ka Polyurethane kahi mea māmā me ka lewa kiʻekiʻe a me ka hoʻolālā pūnaewele wehe.Hana ʻia ka polyurethane e ka hopena o kahi diisocyanate a triisocyanate a me polyols a hiki ke hoʻololi ʻia e ka hoʻokomo ʻana i nā mea ʻē aʻe.
Hiki ke hana ʻia ka polystyrene foam mai ka polyurethane o nā ʻano paʻakikī, a hiki ke hoʻohana ʻia nā mea ʻē aʻe i kāna hana ʻana.Thermoset polyurethane foam ka ʻano maʻamau, akā aia kekahi mau polymers thermoplastic.ʻO nā pōmaikaʻi nui o ka thermoset foam ʻo kona kūpaʻa ahi, versatility a me ka lōʻihi.
Hoʻohana nui ʻia ka polyurethane foam i ka ʻoihana kūkulu ma muli o kāna mau mea kūʻai ahi, māmā a me nā waiwai insulating.Hoʻohana ʻia ia e hana i nā mea hale ikaika akā māmā a hiki ke hoʻomaikaʻi i nā waiwai nani o nā hale.
Nui nā ʻano mea lako a me nā kapena i loaʻa ka polyurethane ma muli o kāna versatility, kumukūʻai-pono a me ka lōʻihi.Pono nā hoʻoponopono EPA e hoʻōla piha ʻia ka mea e hoʻōki i ka hopena mua a pale i nā pilikia ʻona.Eia kekahi, hiki i ka polyurethane foam ke hoʻomaikaʻi i ka pale ahi o nā moena a me nā lako.
ʻO ka pulupulu polyurethane foam (SPF) kahi mea hoʻolalelale mua e hoʻomaikaʻi i ka ikehu o ka hale a me ka hōʻoluʻolu o ka mea noho.ʻO ka hoʻohana ʻana i kēia mau mea insulation e hōʻemi ana i ka hoʻokuʻu ʻia ʻana o ke kinoea greenhouse a hoʻomaikaʻi i ka maikaʻi o ka ea o loko.
Hoʻohana pū ʻia nā adhesives PU i ka hana ʻana i nā huahana lāʻau e like me MDF, OSB a me ka chipboard.'O ka versatility o PU 'o ia ho'i e hiki ke ho'ohana 'ia no nā 'ano like 'ole e like me ke kani 'ana a me ke kū'ē 'ana, ke kū'ē wela loa, ke kū'ē o ka pulu, ke kū'ē kahiko, a me nā mea'ē a'e.
ʻOiai he mea pono loa ka polyurethane foam a hoʻohana ʻia i nā ʻano he nui o ke kūkulu hale, aia kekahi mau pilikia.I nā makahiki i hala iho nei, ua nīnau nui ʻia ka hoʻomau ʻana a me ka hana hou ʻana o kēia mea, a ua maʻa mau ka noiʻi e hoʻoponopono i kēia mau pilikia i ka palapala.
ʻO ke kumu nui e kaupalena ana i ka launa ʻana o ke kaiapuni a me ka recyclable o kēia mea, ʻo ia ka hoʻohana ʻana i nā isocyanates reactive a ʻona i ka wā o kāna hana hana.Hoʻohana pū ʻia nā ʻano catalysts a me nā surfactants e hana i nā pua polyurethane me nā waiwai like ʻole.
Ua manaʻo ʻia aia ma kahi o 30% o ka polyurethane foam i hana hou ʻia e pau i ka pae ʻāina, kahi pilikia nui kaiapuni no ka ʻoihana kūkulu no ka mea ʻaʻole hiki ke biodegradable ka mea.Ma kahi o ka hapakolu o ka polyurethane foam i hana hou ʻia.
Nui nā mea e hoʻomaikaʻi ʻia ma kēia mau wahi, a no kēia hopena, ua ʻimi nā noiʻi he nui i nā ala hou no ka hana hou ʻana a me ka hoʻohana hou ʻana i ka polyurethane foam a me nā mea polyurethane ʻē aʻe.Hoʻohana mau ʻia nā ʻano hana hoʻopōmaikaʻi kino, kemika a me ke olaola no ka hoʻihoʻi ʻana i ka pahu polyurethane no ka hoʻohana ʻana i ka waiwai.
Eia nō naʻe, ʻaʻohe koho hana hou i kēia manawa e hāʻawi i kahi huahana kiʻekiʻe, hiki ke hoʻohana hou, a paʻa.Ma mua o ka hiki ke noʻonoʻo ʻia ʻo ka polyurethane foam recycling he koho kūpono no ke kūkulu ʻana a me ka ʻoihana lako, pono e hoʻoponopono ʻia nā mea pale e like me ke kumukūʻai, ka haʻahaʻa haʻahaʻa a me ka nele o ka hana hou ʻana.
ʻO ka pepa, i paʻi ʻia ma Nowemapa 2022, e ʻimi ana i nā ala e hoʻomaikaʻi ai i ka hoʻomau a me ka hana hou ʻana o kēia mea hale koʻikoʻi.ʻO ka haʻawina, i hana ʻia e nā ʻepekema mai ke Kulanui o Liege ma Belgium, ua paʻi ʻia ma ka puke pai ʻo Angewandte Chemie International Edition.
ʻO kēia ala hou e pili ana i ka hoʻololi ʻana i ka hoʻohana ʻana i nā isocyanates ʻona a me ka reactive me nā mea ʻoi aku ka maikaʻi o ke kaiapuni.Hoʻohana ʻia ʻo carbon dioxide, kekahi mea hoʻopōʻino ʻino i ke kaiapuni, ma ke ʻano he mea maka i kēia ʻano hana hou o ka hana ʻana i ka ʻōmaʻomaʻo polyurethane foam.
Ke hoʻohana nei kēia kaʻina hana hoʻomau i ke kaiapuni i ka wai e hana ai i ka mea hoʻohua, e hoʻohālike ana i ka ʻenehana huʻihuʻi i hoʻohana ʻia i ka hoʻoili ʻana i ka polyurethane foam maʻamau a pale maikaʻi i ka hoʻohana ʻana i nā isocyanates pōʻino kūlohelohe.ʻO ka hopena hopena he ʻōmaʻomaʻo polyurethane foam i kapa ʻia e nā mea kākau ʻo "NIPU."
Ma waho aʻe o ka wai, hoʻohana ke kaʻina hana i kahi catalyst e hoʻohuli i ka cyclic carbonate, kahi ʻōmaʻomaʻo hou i isocyanates, i carbon dioxide e hoʻomaʻemaʻe i ka substrate.I ka manawa like, paʻakikī ka ʻōhū ma ka hana ʻana me nā amine i loko o ka mea.
ʻO ke kaʻina hana hou i hōʻike ʻia ma ka pepa e hiki ai i ka hana ʻana i nā mea polyurethane paʻa haʻahaʻa haʻahaʻa me ka puʻupuʻu pore maʻamau.ʻO ka hoʻololi kemika o ka ʻōpala carbon dioxide e maʻalahi ke komo i nā carbonate cyclic no nā kaʻina hana.ʻO ka hopena he hana pālua: ka hoʻokumu ʻana i kahi mea hoʻoulu a me ka hoʻokumu ʻana i kahi matrix PU.
Ua hana ka hui noiʻi i kahi ʻenehana modular maʻalahi, maʻalahi e hoʻokō, i ka wā i hui pū ʻia me kahi huahana hoʻomaka e hoʻomaka ana i ke kaiapuni maʻalahi, e hana i kahi hanauna hou o ka polyurethane foam ʻōmaʻomaʻo no ka ʻoihana kūkulu.No laila e hoʻoikaika ai ka ʻoihana i ka loaʻa ʻana o ka net-zero emissions.
ʻOiai ʻaʻohe ala hoʻokahi e kūpono i ka hoʻomaikaʻi ʻana i ka hoʻomau i ka ʻoihana kūkulu, ke hoʻomau nei ka noiʻi i nā ala like ʻole e hoʻoponopono ai i kēia pilikia koʻikoʻi kaiapuni.
ʻO nā ala hou, e like me ka ʻenehana hou mai ka hui University of Liege, e kōkua nui i ka hoʻomaikaʻi maikaʻi ʻana i ka ʻoluʻolu o ke kaiapuni a me ka recyclability o ka polyurethane foam.He mea koʻikoʻi ka hoʻololi ʻana i nā kemika nui loa i hoʻohana ʻia i ka hana hou ʻana a hoʻomaikaʻi i ka biodegradability o ka polyurethane foams.
Inā hoʻokō ka ʻoihana kūkulu hale i kāna mau hoʻokō net-zero emissions e like me nā pahuhopu honua e hōʻemi i ka hopena o ke kanaka i ka hoʻololi ʻana i ke aniau a me ke ao kūlohelohe, ʻo ka hoʻokokoke ʻana i ka hoʻomaikaʻi ʻana i ka circularity ka mea nui o ka noiʻi hou.ʻIke loa, ʻaʻole hiki ke ʻano "ʻoihana e like me ka maʻamau".

I loko o kēia nīnauele, kūkākūkā ʻo Muriel Gubar, ka luna māhele honua no nā mea kūkulu ma Malvern Panalytical, i nā pilikia hoʻomau o ka ʻoihana sima me AzoBuild.
ʻO kēia International Women's Day, ua hauʻoli ʻo AZoBuild i ke kamaʻilio ʻana me Kauka Silke Langenberg mai ETH Zurich e pili ana i kāna ʻoihana hoihoi a me kāna noiʻi.
'Ōleloʻo AZoBuild iā Stephen Ford, ka luna o Suscons a me ka mea nāna i hoʻokumu iā Street2Meet, e pili ana i nā hana āna e mālama nei no ka hanaʻana i nā hale noho ikaika, lōʻihi a palekana no ka poʻe nele.
E hāʻawi kēia ʻatikala i kahi hiʻohiʻona o nā mea kūkulu hale bioengineered a kūkākūkā i nā mea waiwai, nā huahana, a me nā papahana e hiki ke hiki ma muli o ka noiʻi ʻana i kēia kahua.
Ke piʻi aʻe nei ka pono e decarbonize i ke kaiapuni i kūkulu ʻia a kūkulu i nā hale kalapona-neutral, lilo ka hoʻēmi kalapona i mea nui.
Ua kamaʻilio ʻo AZoBuild me Polofesa Noguchi lāua ʻo Maruyama e pili ana i kā lākou noiʻi a me ka hoʻomohala ʻana i ka calcium carbonate concrete (CCC), kahi mea hou e hiki ai ke hoʻāla i ka loli hoʻomau i ka ʻoihana kūkulu.
Kūkākūkā ʻo AZoBuild a me Lacol i kā lākou papahana hale hui La Borda ma Barcelona, Sepania.Ua koho ʻia ka papahana no ka 2022 EU Prize for Contemporary Architecture - ka Mies van der Rohe Prize.
Kūkākūkā ʻo AZoBuild i kāna papahana hale kaiapuni 85-home me EU Mies van der Rohe Award finalist Peris+Toral Arquitectes.
Me 2022 ma kahi kokoke i ke kihi, ke ulu nei ka hauʻoli ma hope o ka hoʻolaha ʻana o ka papa inoa pōkole o nā ʻoihana hoʻolālā i koho ʻia no ka European Union Prize for Contemporary Architecture - ka Mies van der Rohe Prize.
