HPMC no ka Honeycomb Ceramics

ʻO HPMC, a i ʻole hydroxypropyl methylcellulose, he ʻano o ka polymer-based cellulose i hoʻohana ʻia i nā ʻano hana like ʻole, me ke ʻano he mea hoʻopaʻa i nā seramika honeycomb. ʻO ka honeycomb ceramics kahi ʻano o nā mea seramika i hana ʻia me kahi pūnaewele o nā cell i hoʻopili ʻia, hiki ke hoʻohana ʻia i nā ʻano hana like ʻole, e like me nā kānana, catalysts, a me nā mea hoʻololi wela. ʻO ka HPMC kahi mea hoʻopili kūpono no ka honeycomb ceramics ma muli o kona ikaika paʻa kiʻekiʻe, ke kumu kūʻai haʻahaʻa, a me ka maʻalahi o ka hoʻohana.

ʻO ka HPMC he polymer hiki ke hoʻoheheʻe ʻia i ka wai i hana ʻia me nā molekole cellulose i hoʻololi ʻia me nā hui hydroxypropyl. Hoʻololi kēia hoʻololi i ka polymer i ʻoi aku ka hoʻoheheʻe wai a hāʻawi iā ia i ka ikaika hoʻopaʻa kiʻekiʻe ma mua o nā polymers-based cellulose. Paʻa loa ka HPMC a hiki ke kū i nā wela kiʻekiʻe, e lilo ia i mea hoʻopaʻa kūpono no nā seramika honeycomb.

Ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa i nā seramika honeycomb, ua hui pū ʻia ʻo HPMC me nā mea ʻē aʻe, e like me ka pālolo, silica, a me ka alumina, e hana i kahi slurry. A laila, ninini ʻia kēia slurry i loko o kahi mole a ʻae ʻia e maloʻo. I ka maloʻo ʻana o ka slurry, hoʻopaʻa ka HPMC i nā mea ʻē aʻe i hui pū ʻia, e hana ana i kahi seramika honeycomb ikaika a paʻa.

Hoʻohana pū ʻia ʻo HPMC i nā noi ʻē aʻe, e like me nā adhesives, coatings, a me nā huahana pepa. Ma kēia mau noi, hāʻawi ʻo HPMC i kahi paʻa paʻa ma waena o nā papa ʻelua, e lilo ia i koho kūpono no nā huahana like ʻole.

ʻO ka HPMC kahi mea hoʻopaʻa maʻalahi a maikaʻi hoʻi no ka honeycomb ceramics. He maʻalahi ke hoʻohana, he ikaika hoʻopaʻa kiʻekiʻe, a paʻa i nā wela kiʻekiʻe. ʻAʻole ʻona a pili kaiapuni ʻo HPMC, e lilo ia i koho kūpono no nā ʻano noi like ʻole.
