He mea nui ka huʻa polyurethane (PU foam) i nā ʻoihana he nui, me ke kūkulu ʻana, ka hana ʻana i nā kaʻa, ka hoʻopili ʻana, a me ka insulation. ʻO ke kaʻina hana o ka huʻa PU e pili ana i ka hopena o nā polyols me nā isocyanates, a ʻo nā catalysts e kāohi i ka wikiwiki o ka hopena, ke ʻano o ka huʻa, a me ke ʻano o ka huʻa.Nā mea hoʻouluulu polyurethanee like me MXC-37 (DMAEE) e pāʻani i kahi hana koʻikoʻi i kēia mau noi, e hoʻomaikaʻi ana i nā waiwai o ka huʻa a me ka hoʻonui ʻana i ka pono hana. E hoʻolauna kēia ʻatikala i nā wahi noi o ka huʻa PU a wehewehe i ke ʻano o ka hoʻokumu ʻana o ka huʻa, e kālele ana i ke kuleana o MXC-37.
Nā noi o ka Polyurethane Foam
Hoʻohana ʻia ka huʻa polyurethane i nā ʻano hana like ʻole ma muli o kāna mau hoʻohana he nui, e like me ka insulation thermal maikaʻi loa, ka omo haʻalulu, a me nā waiwai māmā. ʻO nā ʻano nui ʻelua o ka huʻa polyurethane, ka huʻa paʻa a me ka huʻa palupalu, e hoʻokō i nā pono ʻoihana like ʻole.
Huʻa polyurethane paʻa: Hoʻohana nui ʻia ka huʻa polyurethane paʻa no nā noi insulation thermal. Ma muli o kona mau waiwai insulation thermal maikaʻi loa, hoʻohana pinepine ʻia ia i ke kūkulu ʻana i nā hale, nā pahu hau, nā pahu hau, nā ʻāpana mālama anu, a me ka halihali ʻana i nā waiwai e pili ana i ka mahana. ʻO ka maʻamau, he mau pūnaewele pani ʻia nā huʻa paʻa, e kōkua ana iā lākou e mālama i ko lākou ikaika, kūpaʻa, a me nā waiwai insulation thermal.
Huʻa polyurethane palupalu: Hoʻohana nui ʻia ka huʻa polyurethane palupalu i ka hana ʻana i nā moena, nā uluna, nā noho kaʻa, a me ka insulation thermal no nā paipu a me nā pahu. Hāʻawi ia i ka ʻoluʻolu, ke kākoʻo, a me ka omo leo maikaʻi loa, e lilo ia i koho kaulana i nā ʻoihana lako a me nā kaʻa.
Nā huʻa kūikawā: Hiki ke hoʻohana ʻia nā huʻa polyurethane i nā noi kūikawā, e like me ka hana ʻana o nā huʻa microcellular, elastomers, a me nā mea hoʻopili huʻa paʻa. Loaʻa i kēia mau huʻa nā waiwai kūikawā e hoʻokō ai i nā koi kikoʻī e like me ke kūpaʻa kiʻekiʻe, ka maʻalahi, a me ka hōʻemi kaumaha.
ʻAno Hana Hoʻokumu ʻana o ka Polyurethane Foam
ʻO ke kaʻina hana o ka hoʻokumu ʻana i ka huʻa polyurethane e pili ana i ka hopena ma waena o nā polyols a me nā isocyanates, i kōkua ʻia e nā catalysts, nā mea puhi, a me nā mea hoʻopaʻa. Hoʻopuka kēia hopena i kahi matrix polymer a me nā pehu kinoea, e hopena ana i ka ʻano huʻa. Hiki ke hoʻokaʻawale ʻia ke ʻano ma hope o kēia hoʻokumu ʻana i ka hoʻokumu ʻana o ka huʻa cell open a me ka huʻa cell closed.
1. Ka Hoʻokumu ʻana o ka Huʻa Kelepona Hāmama
Hoʻokumu ʻia ka huʻa open-cell ke haki nā pehu i hana ʻia i ka wā o ke kaʻina hana huʻa ma muli o ke kaomi kinoea kiʻekiʻe i loko o ka pehu. Ke piʻi aʻe ke kaomi i loko o nā pehu, ʻo nā paia pehu, i hana ʻia e ka hopena gel, nele pinepine i ka ikaika e kū i ke kaomi kinoea kūloko. ʻO kēia ke alakaʻi i ka haki ʻana a me ka hoʻokuʻu ʻia ʻana o ke kinoea mai ka pehu. ʻO ka hopena, lilo ke ʻano huʻa i open-cell.
ʻO ka hoʻokumu ʻia ʻana o ka huʻa open-cell ua hoʻopili nui ʻia e ka wikiwiki o ka gelation a me ka ikaika o nā paia polymer. ʻO ka pakeneka o nā cell hāmama i loko o ka huʻa he hopena koʻikoʻi i nā waiwai o ka mea. No ka laʻana, hiki i ka nui o ka ʻike o ka open-cell ke hoʻonui i ka permeability makū, hoʻemi i nā waiwai insulation, a hoʻopilikia i ke kūpaʻa dimensional o ka huʻa. I ka hapa nui o nā huʻa paʻa, haʻahaʻa ka ʻike o ka open-cell, maʻamau ma waena o 5% a me 10%, me ke koena 90% a 95% i hana ʻia me nā cell pani.
2. Ka Hoʻokumu ʻana o ka Huʻa Kelepona Paʻa
ʻIke ʻia nā huʻa kelepona pani ʻia e ko lākou ʻano cell paʻa a like, kahi i hoʻopaʻa ʻia ai ke kinoea i loko o nā cell, e hana ana i kahi huʻa paʻa a paʻa. ʻO ka wikiwiki o ka gel i loko o nā ʻōnaehana huʻa kelepona pani ʻia he wikiwiki maʻamau, i hoʻomaʻamaʻa ʻia e nā polyols polyether multi-functional, haʻahaʻa-molecular-weight a me nā polyisocyanates. Hōʻoia kēia mau ʻōnaehana pane wikiwiki ʻaʻole i loaʻa i ke kinoea i loko o nā pehu ka manawa e pakele ai ma mua o ka paʻa ʻana o ka huʻa, e hopena ana i kahi ʻano huʻa i hoʻomalu ʻia e nā cell pani.
Hāʻawi nā ʻōhū polyurethane paʻa-kelepona pani i ka insulation ʻoi aku ka maikaʻi a hoʻohana pinepine ʻia i nā ʻoihana e like me ke kūkulu ʻana, kahi e koʻikoʻi ai nā waiwai insulation thermal. Loaʻa pū lākou i ka hoʻohana ʻana i nā noi mālama anu ma muli o ko lākou hiki ke mālama i ka wela a pale aku i ke komo ʻana o ka makū.
Ke kuleana oMXC-37 (DMAEE)ma ka hana ʻana i ka polyurethane foam
ʻO MXC-37, i ʻike ʻia hoʻi ʻo DMAEE (Dimethylaminoethoxyethanol), he mea hoʻoulu amine ʻala ʻole i hoʻokuʻu ʻia, i hoʻohana nui ʻia i ka hana ʻana i nā huʻa polyurethane. ʻO kāna hana huʻa kiʻekiʻe e kūpono loa ia no nā ʻano hana me ka nui o ka wai, e like me ka huʻa polyurethane spray porous haʻahaʻa (SPF) i hoʻoulu ʻia me ka wai.
Hana ʻo MXC-37 ma ke ʻano he mea hoʻoulu e hoʻolalelale i ka hopena isocyanate-polyol, e paipai ana i ka hoʻokumu ʻana o ke ʻano huʻa. ʻO kekahi o nā pono nui o MXC-37 ʻo ia kona hiki ke hōʻemi a hoʻopau paha i ka ʻala amine maʻamau e pili pinepine ʻia me ka hana ʻana o ka huʻa polyurethane. ʻO kēia ka mea kūpono no nā noi kahi e koʻikoʻi ai ka kaohi ʻana i ka ʻala, e like me ka insulation hale noho a me nā ʻoihana.
Ma waho aʻe o kona kūlana ma ke ʻano he mea hoʻoulu mua, hiki ke hoʻohana ʻia ʻo MXC-37 ma ke ʻano he mea hoʻoulu like me nā mea hoʻoulu amine ʻē aʻe, e like me BDMAEE, e hoʻomaikaʻi i ka pono holoʻokoʻa o ka hopena. Ma ka hoʻēmi ʻana i ka hoʻohana ʻana i nā amine ikaika, kōkua ʻo MXC-37 i ka hōʻemi ʻana i nā hoʻokuʻu ʻana, e lilo ia i koho aloha kaiapuni no ka hana ʻana i ka huʻa polyurethane.
Hoʻohana ʻia ʻo MXC-37 i nā ʻano hana huʻa like ʻole, e like me:
- Nā huʻa palupalu hoʻopaʻa esterNo nā noi e pono ai nā huʻa palupalu a maʻalahi hoʻi.
- Nā huʻa microcellularNo ka kaohi pololei ʻana i ka ʻano o ka huʻa.
- Nā Elastomers a me RIM: I ka hana ʻana i nā mea huʻa palupalu a paʻa.
- ʻŌpala huʻa paʻaNo nā noi e pono ai ka ikaika mechanical kiʻekiʻe a me ka insulation thermal.
Hopena
He mea maʻalahi a hoʻohana nui ʻia ka huʻa polyurethane e loaʻa ana ka hoʻohana ʻana ma nā ʻoihana he nui ma muli o kona insulation thermal maikaʻi loa, dampening vibration a me nā waiwai i hiki ke hoʻopilikino ʻia. He kuleana koʻikoʻi nā mea hoʻouluulu e like me MXC-37 i ka hana ʻana o ka huʻa polyurethane no ka mea e kōkua lākou i ka kaohi ʻana i ke kaʻina hana huʻa, hoʻomaikaʻi i ka hana huahana a hōʻemi i nā ʻala a me nā hoʻokuʻu ʻana i makemake ʻole ʻia. ʻO ka hoʻomaopopo ʻana i nā ʻano hana ma hope o ka hoʻokumu ʻia ʻana o nā huʻa, inā he open-cell a i ʻole closed-cell, e hiki ai i nā mea hana ke hoʻopilikino i nā huahana i nā pono kikoʻī, mai nā mea insulation a i nā huʻa kūikawā no nā ʻano ʻoihana like ʻole.
