E like me ka polyurethane rigid foam (PU rigid foam) loaʻa nā hiʻohiʻona o ke kaumaha māmā, ka hopena insulation thermal maikaʻi, ka hana maʻalahi, a me nā mea ʻē aʻe, a he mau hiʻohiʻona maikaʻi hoʻi e like me ke kani ʻana o ke kani, ke kū ʻana o ka haʻalulu, ka insulation uila, ke kūpaʻa wela, ke kūpaʻa anu, ka solvent. kū'ē, a me nā mea'ē aʻe, ua hoʻohana nuiʻia ma ka home a ma waho.Ma ka aerospace, ka hana moku, ka aila, nā lako uila, nā kaʻa, nā meaʻai a me nā ʻoihana ʻoihana ʻē aʻe.
ʻO nā hoʻohana nui o ka PU rigid foam penei:
1. ʻO nā mea hoʻoheheʻe no nā mea hana hale a me nā ʻoihana meaʻai
Nā pahu haua me nā pahu hau e hoʻohana ana i ka puʻupuʻu ʻoʻoleʻa PU e like me ka papa hoʻokuʻu ʻana i kahi ʻāpana ʻokoʻa lahilahi loa.Ma lalo o nā ana o waho like, ʻoi aku ka nui o ka leo kūpono ma mua o ka hoʻohana ʻia ʻana o nā mea ʻē aʻe e like me ka papa insulation, a ua hoʻemi ʻia ke kaumaha o ka mea hana.
Hoʻohana maʻamau nā mea hoʻoheheʻe wai uila, nā mea hoʻomehana wai o ka lā, a me nā mea hoʻoheheʻe pia.Hoʻohana pū ʻia ʻo PU rigid foam i ka hana ʻana i nā incubators portable no ka lawe ʻana i nā huahana biological, nā lāʻau lapaʻau a me nā meaʻai e pono ai ka insulation thermal a me ka mālama ʻana.
2.Nā lako hana a me nāpaipuhoʻokaʻawale
ʻO nā pahu waihona a mepaipunā mea hana maʻamau i ka hana ʻoihana, a hoʻohana nui ʻia i ka petroleum, kūlohelohe kino, hoʻomaʻemaʻe aila, ʻoihana kemika, ʻoihana māmā a me nā ʻoihana ʻē aʻe.ʻO ke ʻano o ka pahu waihona he spherical a cylindrical paha, a hiki ke kūkulu ʻia ka pua ʻaʻa PU ma o ka pīpī ʻana, ka ninini ʻana a me ka hoʻopili ʻana i ka huʻa prefabricated.Ma ke ano hepaipuka mea hoʻoheheʻe wela, ua hoʻohana nui ʻia no ka insulation thermal o nā pipelines i ka lawe ʻana i ka ailapaipua me nā ʻoihana petrochemical, a ua hoʻololi maikaʻi ʻo ia i nā mea me ka nui o ka wai e like me ka perlite.
3. Nā mea kūkulu hale
ʻO ke kūkulu hale kekahi o nā kahua noi nui loa o ka PU rigid foam.Ma Kina, ua hoʻolaha ʻia ka ʻūhū paʻa no ka insulation thermal a me ka wai wai o nā hale o nā hale noho a me nā hale keʻena,hale mea hoʻokaʻawale, a me na mea hookuku wela nolumi anu, nā waihona palaoa, a me nā mea'ē aʻe. Hoʻohanaʻia ka'ōhū paʻakikī i hoʻopiliʻia no ka hale, a ua hoʻohuiʻia ka pale pale, a he mau hopena lua o ka hoʻouluʻana i ka wela a me ka waiʻole.

Nā lolemannequinshe kahua noi hou i ka ʻoihana polyurethane.Nā hiʻohiʻonaʻo ia kekahi o nā mea pono i loko o kahi hale kūʻai lole.Hiki iā lākou ke kāhiko i ka hale kūʻai a hōʻike i nā mea koʻikoʻi o ka lole.Hana ʻia nā hiʻohiʻona lole e kū nei ma ka mākeke me ka fiberglass fiber, plastic a me nā mea ʻē aʻe.ʻAʻole maikaʻi ke aahu ʻana o ka fiberglass fiber, he palupalu, a ʻaʻohe elasticity.Loaʻa i nā plastik nā hemahema e like me ka ikaika ʻino a me ke ola pōkole.ʻO ke kumu hoʻohālike o ka lole polyurethane nā mea maikaʻi o ke kūpaʻa lole maikaʻi, ka ikaika maikaʻi, ka elasticity, ka hana cushioning maikaʻi, a me ke kiʻekiʻe o ka simulation.
7.Other noi maʻamau
Ma waho aʻe o nā noi i luna, hiki ke hoʻohana ʻia ka polyurethane rigid foam no ka hoʻopiha ʻana i ka puka a me ka hana ʻana i nā pōpō lana iʻa, etc.
ʻO ka puka polyurethane hoʻopiha ʻia e like me nā puka ʻē aʻe, akā naʻe, ʻokoʻa ke ʻano o loko.ʻO ka mea maʻamau, ʻaʻole i ʻōmaʻomaʻo wale ka ʻōmaʻomaʻo a me ke kaiapuni o ka puka pena, a i hoʻopiha ʻia me ka pepa honeycomb, ʻoiai ʻo ka polyurethane rigid foam-filled door ʻaʻole wale wale nō ka ʻōmaʻomaʻo a me ke kaiapuni, akā e hoʻoikaika pū i ka paʻakikī o ka puka puka, e ikaika a ikaika ai ka puka. , ina paha he kaumaha mea kaumaha, ka wai ohu, Ina paha i wela i ke ahi, hiki ia ia ke hooiaio aole loa ia e deformed.Hoʻopau kēia ʻenehana i nā puka composite, Hiki i nā puka lāʻau ke pilikia i nā pilikia e like me ka deformation a me ka wai.
