Mea kiʻekiʻe Polyurethane a me nā isocyanates kūikawā 1,5-Naphthalene Diisocyanate(NDI) CAS 3173-72-6

ʻO NDI (1,5-Naphthalene Diisocyanate) kahi mea maka o ka polyurethane kiʻekiʻe, hiki ke hoʻohana ʻia e hana i ka polyurethane elastomer me ka elasticity kiʻekiʻe a me ka paʻakikī kiʻekiʻe. He hana maikaʻi loa ka NDI polyurethane elastomer. Loaʻa iā ia ka hana like ʻole me nā elastomer polyurethane ʻē aʻe, e like me ka hana hoʻoikaika maikaʻi loa, ka hana mechanical kiʻekiʻe loa, ke kūpaʻa ʻoki maikaʻi loa, ka pale ʻana i ka lole a me ke kūpaʻa wela. No laila, hoʻohana nui ʻia ka NDI polyurethane elastomers i nā mea hoʻoheheʻe kaʻa, nā huila forklift, ka paʻi ʻana a me ka waihoʻoluʻu ʻana i nā wili lole lole, nā ʻōpala ʻōpala, nā poloka pale kūkulu alahaka, nā ʻoihana koa, etc.

ʻO ka elastomer castable i hana ʻia e NDI he mau hiʻohiʻona maikaʻi loa a me ke kūpaʻa ʻana, a me ka damping liʻiliʻi, ke kūpaʻa kiʻekiʻe, a me ka liʻiliʻi o ka wela o loko. Hiki ke hoʻohana ʻia i nā haʻahaʻa ikaika kiʻekiʻe a me nā manawa wela. ʻO nā huahana i hoʻoheheʻe ʻia i hana ʻia me NDI he ikaika waimaka kiʻekiʻe, haʻahaʻa haʻahaʻa, hoʻonohonoho haʻahaʻa haʻahaʻa a me ke kūpaʻa maikaʻi loa. NDI-based microporous polyurethane elastomer huahana he haʻahaʻa endogenous wela, liʻiliʻi deformation mau a me ka rigidity maikaʻi ma lalo o ka dynamic ukana. Hoʻohana nui ʻia kēia mea microporous polyurethane kūikawā no ka hoʻoheheʻe ʻana i nā kaʻa a me nā ʻāpana cushioning.
