ʻO ka polyurethane elastomer kahi ʻano mea i hoʻohana nui ʻia, he maʻalahi maikaʻi kona, kūpaʻa a me ke kūpaʻa ʻana i ka ʻaʻahu, no laila ua hoʻohana nui ʻia ia ma nā ʻano āpau o ke ola. ʻO kekahi o nā mea nui i ka hana ʻana o nā polyurethane elastomers ʻo ia ka hoʻohana ʻana i nā catalysts e hoʻolalelale i nā hopena kemika i ka wā o ka hoʻokumu ʻana o ka mea hope loa. He mea nui kēia mau catalysts no ka kaohi ʻana i ke kaʻina hana polymerization, e hōʻoia ana i ka hoʻokō ʻia ʻana o nā waiwai i makemake ʻia o ka elastomer. Ma waena o nā catalysts like ʻole i loaʻa, loaʻa iā MXC-A33 kahi ʻano hana kū hoʻokahi e hiki ke hoʻohana ʻia i loko o kahi ākea o nā polyurethane foams a me nā elastomers.
He aha ka meaMXC-A33?
He mea hoʻonui polyurethane ʻo MXC-A33 e hoʻoikaika i ka hopena ma waena o nā polyols a me nā isocyanates, ʻo ia nā ʻāpana nui o nā mea polyurethane. Hana ʻia ka mea hoʻonui me 33% TEDA (triethylene diamine) a me 67% DPG (monoconjugated dipropylene glycol). Hāʻawi kēia ʻano hana kikoʻī i ka hana kūpono loa i ka hana ʻana o nā polyurethane foam a me nā elastomers.
- TEDA (Triethylenediamine)He mea hoʻonui amine tertiary kūpono loa e hoʻolaha ana i ka hopena gelling ma waena o nā hui hydroxyl a me isocyanate.
- DPG (Dipropylene Glycol i hoʻohuihui ʻia)He mea hoʻoheheʻe e kōkua ai i ka hōʻemi ʻana i ka mānoanoa a hoʻonui i ka hui ʻana o nā mea, e hōʻoiaʻiʻo ana i kahi kaʻina hana maʻalahi.
Hoʻohana ʻia ma nā Polyurethane Elastomers
Hoʻohana nui ʻia ʻo MXC-A33 i ka hana ʻana o nā elastomers polyurethane ma muli o kona hopena catalytic kaulike, ka mea e hōʻoiaʻiʻo ai e hana ʻia ka hopena polymerization ma kahi wikiwiki i kāohi ʻia. He mea nui kēia reactivity i kāohi ʻia no ka hana ʻana o nā elastomers me nā waiwai mechanical i makemake ʻia e like me ka elasticity, ka ikaika tensile a me ke kūpaʻa ʻana i ka ʻaʻahu.
Hoʻoulu ka mea hoʻoulu i ka hoʻokumu ʻana o nā ʻano polymer crosslinked like, hiki ke hoʻokō i ka hana o nā elastomers i nā noi koi. Hoʻohana pinepine ʻia nā elastomers polyurethane i hana ʻia mai MXC-A33 i nā ʻāpana kaʻa, nā wili ʻoihana, a me nā sila hana kiʻekiʻe, kahi e kau ai i nā koi kiʻekiʻe ma ko lākou kūpaʻa a me ka elasticity.
Hopena
ʻO ka hoʻohana ʻana onā mea hoʻouluulu polyurethanee like me MXC-A33 i ka hana elastomer he mea nui ia i ka hōʻoia ʻana i ka hana a me ka hilinaʻi o ka mea. ʻO kāna hui kūikawā o TEDA a me DPG e hoʻolilo iā ia i mea kūpono loa no nā noi huʻa a me elastomer, e hiki ai i nā mea hana ke hana i nā huahana kiʻekiʻe a paʻa no nā ʻano ʻoihana like ʻole.
