Pilikia Poʻo Poʻo Paʻa Nui no ka Insulation
Hoʻokaʻawale
ʻO nā pōhaku lepo pōleʻa alumina a me nā pōhaku lepo pōʻalo Zirconia
wehewehe
Hana ʻia nā pōhaku lepo alumina me ka pōpō alumina a me ka pauka alumina ma ke ʻano he kumu waiwai nui, i hui pū ʻia me nā mea hoʻopaʻa ʻē aʻe, ma hope o 1750 degere kiʻekiʻe kiʻekiʻe kiʻekiʻe, pili i ke ʻano o ka wela ultra-kiʻekiʻe a me ka hoʻōla ʻana i ka ikehu.
Nā hiʻohiʻona
ʻO nā pōhaku lepo pōleʻa alumina he nui ka nui o ka porosity paʻa, no laila he ikaika kiʻekiʻe a me ka paʻa o ka hoʻolālā porosity, haʻahaʻa haʻahaʻa, maikaʻi thermal haʻalulu a me ka liʻiliʻi liʻiliʻi o ka laina mau loa, haʻahaʻa thermal conductivity.
ʻO nā pōhaku lepo pōʻalo Zirconia me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻana i ka corrosion, ka pale ʻana i ka oxidation, ke kūpaʻa ʻana, ka expansivity thermal nui.ʻO nā huahana zirconia hollow ball i hana ʻia e ka zirconia hollow ball, me ka ikaika wela kiʻekiʻe a me ke kūpaʻa o ka hoʻolālā porosity.
Palapala noi
Hoʻohana nui ʻia nā pōhaku lepo pōleʻa alumina i ka reactor gasifier o ka ʻoihana petrochemical, carbon black industry, induction furnace of metallurgical industry, down-draft kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nitrogenation umu, a me nā mea kiʻekiʻe. wela, nā kapuahi wela kiʻekiʻe loa.
Zirconia hollow poepoe pōhaku lepo i hoʻohana 'ia i ka ultra kiʻekiʻe wela lako e like me ka umu uhi uhi wahi o ka thermal insulation mea, e like me ke alapine pinepine kiʻekiʻe wela umu, kalaponaʻeleʻele reactor, molybdenum uea umu, tungsten koʻokoʻo umu ahi, etc. ʻO ka mahana hana he 2200 ℃, i ka metallurgical, petrochemical, electronic a me nā mea ʻenehana ʻoihana ʻē aʻe e like me ka hoʻopili pololei ʻana me ka lapalapa o ke kiʻekiʻe wela o nā mea lining, hoʻohana maikaʻi ka hopena.
