Hoʻohana nui ʻia ka huʻa polyurethane ma nā ʻoihana like ʻole ma muli o kona versatility, nā waiwai insulating a me nā ʻano kūkulu. Hiki ke ʻokoʻa loa nā waiwai o nā huʻa ma muli o ko lākou ʻano cell, hiki ke hoʻokaʻawale ʻia i nā huʻa cell hāmama a i ʻole nā huʻa cell pani. ʻO ke koho ʻana o nā catalysts i hoʻohana ʻia i ka hana ʻana o ka huʻa polyurethane he kuleana koʻikoʻi ia i ka hoʻoholo ʻana i nā waiwai o ka huʻa, me kona density, ka maʻalahi, a me ke ʻala. Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa ma waena o nā huʻa cell hāmama a me nā huʻa cell pani a nānā pehea e hiki ai ke hoʻohana ʻia nā catalysts polyurethane kūikawā e like me MXC-T a me MXC-37 i ka hana ʻana.
Ke Hoʻomaopopo ʻana i nā Huʻa Kelepona Hāmama a me nā Huʻa Kelepona Paʻa
Huʻa Kelepona Hāmama
ʻIke ʻia ka huʻa open-cell e nā cell huʻa e pili ana kekahi i kekahi e hana i kahi ʻano spongy. ʻOi aku ka māmā o kēia huʻa, ʻoi aku ka maʻalahi, a ʻoi aku ka porous, e hopena ana i ka omo leo maikaʻi loa a me nā waiwai insulation leo. Hoʻohana pinepine ʻia ka huʻa open-cell i nā noi e pono ai ka cushioning, e like me nā lako hale, nā noho kaʻa, a me ka soundproofing. ʻO kona mau ʻano nui ka haʻahaʻa haʻahaʻa, ka maʻalahi kiʻekiʻe, ka hana insulation leo a me ka wela maikaʻi loa, a me ka permeability ea maikaʻi.
Huʻa Kelepona Paʻa
I ka hoʻohālikelike ʻana, ua paʻa a paʻa ka ʻano o ka huʻa cell pani, e pale ana i ke kahe ʻana o ka ea a i ʻole ka wai. ʻOi aku ka mānoanoa o ka huʻa, ʻoi aku ka paʻakikī a ʻoi aku ka maikaʻi o ka pale ʻana i ka makū. He kūpono ka huʻa cell pani no nā noi e pono ai ke kūpaʻa a me ke kūpaʻa wai, e like me ka insulation hale, ka huʻa pīpī no nā hale mālama ikehu, a me nā dashboards kaʻa. ʻO kona mau ʻano nui ka nui o ka mānoanoa, ke kūpaʻa kiʻekiʻe, nā waiwai insulation maikaʻi loa (insulation wela, pale makū), pale wai a me ke kūpaʻa.
Ke kuleana o nā mea hoʻouluulu Polyurethane i ka hana ʻana i ka huʻa
He kuleana koʻikoʻi ko nā mea hoʻouluulu polyurethane i ka hana ʻana i ka huʻa ma o ka hoʻomaʻamaʻa ʻana i ka hopena kemika ma waena o nā polyols (mai nā mea kanu a i ʻole nā kumu petroleum) a me nā isocyanates e hana i nā polyurethanes. Ma muli o nā waiwai huʻa i makemake ʻia, e like me ka density, ka flexibility, a me ke ʻala, hoʻohana ʻia nā mea hoʻouluulu like ʻole.
Loaʻa i nā mea hoʻouluulu e like me MXC-T a me MXC-37 nā pono kūikawā no ka hana ʻana i ka huʻa cell-open a me ka huʻa cell-closed. E nānā pono kākou i nā wahi noi a me nā pono o kēia mau mea hoʻouluulu ʻelua.
MXC-T (CAS 2212-32-0)ma ka hana ʻana i ka huʻa
ʻO MXC-T, i ʻike ʻia hoʻi ʻo TMAEA, he mea hoʻonui amine kūpono, ʻaʻohe hoʻokuʻu ʻana e hāʻawi ana i kahi piʻo pane maʻalahi a he koho ākea no ka hana ʻana i nā ʻano huʻa polyurethane like ʻole. ʻO kahi piʻo pane maʻalahi e ʻae ai i ka hoʻonui ʻana o ka huʻa i kāohi ʻia, he mea nui ia e hōʻoia i ke kūlike o ka maikaʻi a me ka hana o ka huʻa.
Hoʻohana ʻia ma nā Foam Open-Cell a me Closed-Cell
He kūpono loa ka MXC-T i nā noi e pono ai nā ʻala haʻahaʻa a me ka hana catalytic kūpono. Hoʻoulu kāna hana catalytic i ka hopena ma waena o ka urea (wai-isocyanate), kahi e hana pinepine ai me ka matrix polymer ma muli o kāna hui hydroxyl ikaika. ʻO ia ke kumu e hoʻohana pinepine ʻia ai ʻo MXC-T i:
- Hoʻopaʻa Huʻa PīpīHoʻomaopopo ʻo MXC-T i ka loaʻa ʻana o kahi ʻano kūlike o ka huʻa insulation me ka liʻiliʻi o ke ʻala, e kūpono ai no nā noi insulation hale noho a me nā ʻoihana.
- Nā Papa Kuhikuhi KaʻaʻO ke ʻala haʻahaʻa a me ke piʻo pane laumania o MXC-T e lilo ia i koho makemake ʻia i nā noi huʻa kaʻa, e like me nā dashboards a me nā ʻāpana kūloko ʻē aʻe.
MXC-37 (CAS 1704-62-7)ma ka hana ʻana i ka huʻa
ʻO MXC-37, a i ʻole DMAEE, kekahi mea hoʻoulu amine ʻala ʻole me ka hana hoʻohua kiʻekiʻe. He kūpono loa ia no nā ʻano hana e pono ai ka nui o ka wai a hoʻohana pinepine ʻia i ka hana ʻana o nā foams polyurethane spray porous haʻahaʻa (SPF) i hoʻohua ʻia me ka wai. He kūpono kēia mea hoʻoulu no ka hana ʻana i nā foams porous kiʻekiʻe a he ʻano like ko lākou, e lilo ia i mea pono i nā noi like ʻole kahi e pono ai kēlā mau ʻano.
Hoʻohana ʻia ma nā Foam Open-Cell a me Closed-Cell
Ua ʻike ʻia ʻo MXC-37 no kona hiki ke hoʻēmi i ke ʻala amine maʻamau i loko o nā hua polyurethane, e lilo ia i koho ākea no nā wahi koʻikoʻi e like me:
- Huʻa Pīpī Haʻahaʻa (SPF)Hoʻohana nui ʻia ka MXC-37 i nā noi huʻa pīpī haʻahaʻa kahi e kiʻekiʻe ai ka nui o ka wai, a he mea nui ka ʻala liʻiliʻi. Hoʻokomo pū kēia i nā noi i loko o ka insulation, ka uhi hale, a me nā ʻōnaehana paia.
- Huʻa Microcellular: Hiki ke hoʻohana ʻia ʻo MXC-37 e hana i nā huʻa microcellular, i hoʻohana pinepine ʻia i loko o ka ʻōpala, nā ʻāpana kaʻa a me nā noi ʻē aʻe e pono ai nā huʻa māmā a maʻalahi, a me nā huʻa palupalu a me nā elastomers kahi he mau koi koʻikoʻi ka maʻalahi a me ke kūpaʻa.
- ʻUpena Huʻa PaʻaI nā noi hoʻopili ʻana, ʻoiai kahi e pono ai nā waiwai māmā a me ka insulation, he kūpono ka MXC-37 i ka kaohi ʻana i ka nui o ka huʻa a me ka hoʻomaikaʻi ʻana i ke ʻano o ka huʻa.
Hiki ke hoʻohana ʻia ʻo MXC-37 ma ke ʻano he mea hoʻoulu nui a i ʻole he mea hoʻoulu like, ʻoiai ke hui pū ʻia me nā mea hoʻoulu ʻē aʻe e like me BDMAEE, e hoʻomaikaʻi i ka maikaʻi o ka huʻa a hoʻemi i ka pono no nā nui kiʻekiʻe o nā mea hoʻoulu ʻē aʻe.
Hopena
Nā mea hoʻouluulu polyurethanehe mea nui nā mea e like me MXC-T a me MXC-37 no ka hana ʻana o nā huʻa hāmama a me nā huʻa pani ʻia, e kōkua ana i nā mea hana e hoʻokō i nā ʻano huʻa i makemake ʻia me ka hoʻemi ʻana i nā huahana ʻino e like me nā ʻala a me nā hoʻokuʻu ʻana. Ma ke koho ʻana i ka mea hoʻoulu kūpono no kahi ʻano huʻa kikoʻī, hiki i nā mea hana ke hoʻomaikaʻi i ka hana a me ke kūpaʻa o kā lākou huahana.
