Ka Hoʻohana ʻana o nā Polyurethane Catalysts i ka Open-Cellular Polyurethane Foam

He mea huʻa maʻalahi ka polyurethane foam a hoʻohana pinepine ʻia, nona ka versatility i nā ʻoihana like ʻole. Hoʻohana ʻia ia ma ka hapa nui o nā lako hale o loko ma ʻAmelika Hui Pū ʻIa a ma waho, ʻoi aku hoʻi ma ka ʻoihana lako hale, kahi e loaʻa ai nā ʻano densities a me ka paʻakikī like ʻole e kūpono ai no nā ʻano hana like ʻole, i hoʻohana pinepine ʻia i ka upholstery, nā moena, nā uluna a me ka insulation. ʻO ka huʻa polyurethane open-cell, ma ke ʻano kūikawā, he palupalu, maʻalahi a māmā hoʻi, e lilo ia i koho mua no nā huahana e pono ai ka ʻoluʻolu a me ke kūpaʻa. Hoʻonui ke ʻano porous o kēia huʻa i kona mau waiwai insulation thermal a me ke kani, e kūpono ai no nā ʻano hana like ʻole mai ka hoʻonaninani o loko a hiki i nā mea insulating.

Nā mea hoʻouluulu e like meMXC-A33a he kuleana koʻikoʻi ko MXC-T i ka hana ʻana i ka huʻa polyurethane cell hāmama. Hoʻomaʻamaʻa kēia mau mea hoʻoulu i ke kaʻina hana huʻa ma ka hoʻolalelale ʻana i ka hopena kemika ma waena o nā isocyanates, e like me toluene diisocyanate a i ʻole TDI, a me nā polyols. ʻO kā lākou kuleana ka hōʻoia ʻana e hana ka huʻa i kona ʻano open-cell, e hopena ana i kahi mea e hanu a elastic hoʻi.

Hiki ke hoʻohana ʻia ʻo MXC-A33 no nā pehu palupalu, paʻakikī a me nā pehu hapa-paʻakikī. Hiki iā ia ke hoʻoheheʻe i nā mea hoʻoheheʻe ʻē aʻe e like me MEG, DEG, BDO, a pēlā aku, no nā noi like ʻole.

MXC-Thoʻohana ʻia e hana i nā hua polyether flexible, nā hua i hoʻoheheʻe ʻia, nā hua semi-rigid a me nā hua paʻa. Hoʻohana nui ʻia ia i nā kaʻa.

Hoʻohana nui ʻia ka huʻa polyurethane open-cell i nā uluna lako hale i loko a me waho, nā moena huʻa hoʻomanaʻo, nā uluna noho a me nā ʻōpala lapaʻau ma muli o kona hiki ke kūpono i ke ʻano o ke kino a hāʻawi i ka ʻoluʻolu. ʻO kona palupalu a me ka maʻalahi, i hui pū ʻia me nā waiwai insulation thermal a me ke kani maikaʻi loa, e lilo ia i koho kaulana no ka insulation mālama ikehu i nā hale.

I ka hōʻuluʻulu manaʻo, ʻo ka hoʻohana ʻana i nā mea hoʻouluulu polyurethane e like me MXC-A33 a me MXC-T i ka hana ʻana o nā hua hāmama e hoʻomaikaʻi i ka hana huʻa, e hōʻoia ana e hoʻokō ka huahana hope loa i nā ʻano e pono ai no kahi ākea o nā noi e like me nā lako a me nā mea insulation. Ua hana ʻo Mingxu Chemical Company i nā mea hoʻouluulu polyurethane no nā makahiki he 20 a ʻoi, loaʻa iā mākou ke ala hana maikaʻi loa a me ka hui ʻoihana e hoʻomaikaʻi a hoʻonui i nā huahana catalyst no ka mākeke, kahi lako nui, hoʻokipa i nā mea kūʻai aku e hele mai e kūkākūkā.
