He mau mea hana like ʻole nā elastomers polyurethane e hōʻike ana i nā waiwai mechanical maikaʻi loa e like me ke elasticity kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa. ʻO kēia mau waiwai e kūpono ai lākou no nā ʻano hana ʻoihana like ʻole, me nā ʻāpana kaʻa, nā kāmaʻa, nā sila a me nā uhi. Pono ka hana ʻana o nā elastomers polyurethane i ka kaohi pololei o nā hopena kemika i komo, ʻoiai ke hana ʻana i ka pilina urethane ma waena o ka polyol a me ka isocyanate. He kuleana koʻikoʻi nā mea hoʻouluulu polyurethane ma aneʻi.
Nā mea hoʻouluulu polyurethanehiki ke kāohi i ka wikiwiki a me ka pono o ka hopena polyurethane. Hoʻopili lākou i ke kaulike ma waena o ka gelation (polyol-isocyanate) a me nā hopena foaming (wai-isocyanate), ka mea e hoʻoholo pololei ai i nā waiwai hope loa o ka elastomer. Ma ke koho ʻana i ka catalyst kūpono, hiki i nā mea hana ke hoʻomaikaʻi i nā kūlana hana a hoʻoponopono i nā waiwai kino o ka elastomer e hoʻokō i nā koi noi kikoʻī.
ʻO kahi mea hoʻonui koʻikoʻi i hoʻohana ʻia i ka hana ʻana o nā elastomers polyurethane ʻo MXC-37, i ʻike ʻia hoʻi ʻo dimethylethanolamine ether (DMAEE).MXC-37 he mea hoʻoulu amine haʻahaʻa-hoʻokuʻu, haʻahaʻa-ʻala i hoʻohana nui ʻia i nā noi e koi ana i nā hoʻokuʻu amine liʻiliʻi a me ka hana kiʻekiʻe. ʻO nā waiwai kū hoʻokahi o MXC-37 e kūpono loa ia no ka ester-based stabilizer soft foam, microcellular foam, elastomers, reaction injection molding (RIM) a me nā noi hoʻopili foam paʻa.
MXC-37i loko o nā Elastomers Polyurethane
MXC-37Hāʻawi ia i kekahi mau pono i ka hana ʻana o nā elastomers polyurethane. He mea hoʻoulu ikaika loa ia e hoʻonui ai i ke kaʻina hana hoʻohua a kūpono loa no nā ʻano hana me ka nui o ka wai. ʻO kāna hana hoʻohua kiʻekiʻe e paipai i ka hoʻokumu ʻana o ka pehu maikaʻi a me ke ʻano like o nā cell, he mea nui ia no nā noi e like me nā hua microcellular a me nā elastomers.
I nā noi elastomer, hōʻoia ʻo MXC-37 i ka hoʻōla wikiwiki a like, kahi e hoʻomaikaʻi ai i nā waiwai mechanical o ka elastomer, e like me ka ikaika tensile i hoʻonui ʻia a me ka maʻalahi. ʻO kēia ka mea e lilo ai ia i koho kaulana no ka hana ʻana i nā ʻāpana elastomer paʻa e pono ai ka elasticity kiʻekiʻe, e like me nā sila, nā gaskets a me nā ʻāpana kaʻa.
Eia kekahi, ʻo nā waiwai ʻala haʻahaʻa a me ka hoʻokuʻu ʻole ʻana o MXC-37 he pono nui nō hoʻi, ʻoiai i nā noi ʻala-sensitive. Hoʻemi ʻia ka ʻala amine e pili pinepine ʻia me nā catalysts polyurethane i ka wā e hoʻohana ai iā MXC-37, e kūpono ai no nā huahana e pili pono ana me nā mea kūʻai aku, e like me nā kāmaʻa a me nā mea cushioning.
Nā Hoʻohana Kūikawā
ʻAʻole i kaupalena ʻia ka versatility o MXC-37 i nā elastomers, akā ua hoʻonui ʻia hoʻi i nā ʻōnaehana polyurethane foam ʻē aʻe. I nā noi microcellular foam, kōkua ia i ka hana ʻana i nā foam me nā pores maikaʻi a like, kahi e hoʻonui ai i ka shock absorption a me nā waiwai cushioning o ka mea. I ka reaction injection molding (RIM), kōkua ʻo MXC-37 i ka hoʻoheheʻe koke ʻana i nā ʻāpana paʻakikī, hoʻonui i ka huahana, a hana i nā ʻāpana māmā a hana kiʻekiʻe no nā noi kaʻa a me nā ʻoihana.
Eia kekahi, hiki ke hoʻohana ʻia ʻo MXC-37 i nā noi hoʻopili huʻa paʻa, kahi e hōʻoia ai kāna hana huʻa kiʻekiʻe i ka insulation a me ka pale pono. ʻO nā waiwai ʻala haʻahaʻa a me ka hoʻokuʻu ʻole o ka catalyst e pōmaikaʻi pū kekahi i kēia mau noi, e hōʻemi ana i ka hopena o ke kaiapuni a hoʻomaikaʻi i nā kūlana hana.
Hopena
I ka hopena, nā mea hoʻouluulu polyurethane e like meMXC-37 (DMAEE)he mau ʻāpana koʻikoʻi i ka hana ʻana o nā elastomers polyurethane a me nā ʻōnaehana huʻa ʻē aʻe. ʻO ko lākou hiki ke kāohi i nā helu hopena, hoʻomaikaʻi i ka maikaʻi o ka huʻa, a hōʻemi i nā hoʻokuʻu ʻala e lilo ia i mea nui loa i nā ʻano noi ʻoihana like ʻole. ʻO MXC-37, me kāna hana huʻa kiʻekiʻe a me nā waiwai haʻahaʻa-hoʻokuʻu, hāʻawi i nā mea hana i kahi hopena hilinaʻi no ka hana ʻana i nā huahana polyurethane hana kiʻekiʻe, mai nā elastomers a i nā huʻa microcellular a me ka ʻōpala huʻa paʻa.
