Alumina Ceramic Part of Insulator
Kahua noi
ʻO ka alumina seramika e hoʻohana nui ʻia ana i ka insulator me ka waiwai mechanical kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka ʻaʻahu lōʻihi, ke kūpaʻa insulation nui, ka pale ʻana i ka corrosion maikaʻi, ka pale wela kiʻekiʻe.
ʻO nā seramika aluminaʻāpanaloaʻa nō hoʻian nā noi koʻikoʻi ma ke kahua o ka insulation.No ka laʻana, ma ke kahua aerospace, hiki ke hoʻohana ʻia nā mea alumina-based fibers e hana i nā mea hoʻoheheʻe wela e like me nā tile pale wela a me nā mea insulation maʻalahi ma nā mokulele mokulele, nā mea pale wela i nā ʻenekini rocket, a me nā mea insulation no nā mea wela kiʻekiʻe i ka mokulele. nā ʻenekini.
Fa i ʻole nā kahua ʻē aʻe,alumina keramikaʻāpanahiki ke hoʻohana ʻia e like me nā mea insulation thermal i nā umu wela wela.Loaʻa i nā mea hoʻohui i hoʻokumu ʻia i ka fiber alumina i nā pono o ka haʻahaʻa haʻahaʻa, ka insulation maikaʻi, a me ka haʻahaʻa haʻahaʻa wela, hiki ke hōʻemi i ke kaumaha o nā umu wela wela.he nuia e hoʻopololei i ka mana wela,pela hikisaveikaika hou aku.
ʻO nā mea hana alumina/resin composite maikaʻi pū kekahi.Loaʻa i kēia mea nā hiʻohiʻona o ka elasticity, ka paʻakikī kiʻekiʻe, a hiki ke hoʻohana ʻia i ka hana ʻana i nā mea haʻuki e like me nā koʻokoʻo lawaiʻa, nā hui kolepa, nā ski, a me nā racket tennis.
Fkūlana kūlana,ka hoʻohana ʻana i nā seramika alumina ma ke kahua o ka insulationhikikōkua i ka hoʻomaikaʻi ʻana i ka hana a me ke ola o nā mea hana, ʻoiai e hōʻemi ana i ka hoʻohana ʻana i ka ikehu.So It ehe koʻikoʻi maikaʻi no ka hāpai ʻana i ka hoʻomohala hoʻomau a me ka mālama ʻana i ke kaiapuni.
Nā kikoʻī
Ka nui koi:1 pc a 1 miliona pcs.ʻAʻohe palena MQQ.
Laʻana manawa alakaʻi:ʻO ka hana hana mea hana he 15 mau lā + hana hoʻohālike 15 lā.
Hana alakai manawa:15 a 45 mau lā.
Uku manawa:kūkākūkā ʻia e nā ʻaoʻao ʻelua.
Kaʻina hana:
ʻO ka alumina (AL2O3) seramika he mea hana ʻenehana nona ka paʻakikī kiʻekiʻe, lōʻihi ke aahu, a hiki ke hana ʻia e ka wili daimana.Hana ʻia ia mai ka bauxite a hoʻopau ʻia e ka hoʻoheheʻe ʻana i ka injection, kaomi ʻana, sintering, wili, sintering a me ka hana machining.
