Nā mea hoʻomehana wela no ka ʻōpala convection o ka paila wela ʻōpala 2

Ma kēia pukana e hoʻomau mākou i ka hoʻolauna ʻana i nā mea insulation i hoʻokumu ʻia.

Nā huahana huluhulu pōhaku: papa hoʻopaʻa huluhulu pōhaku maʻamau i hoʻohana ʻia, me nā waiwai penei: density: 120kg/m3; Mahana hana kiʻekiʻe loa: 600 ℃; Ke 120kg/m3 ka density a ʻo 70 ℃ ka awelika o ka mahana, ʻaʻole ʻoi aku ka conductivity thermal ma mua o 0.046W/(m·k).
ʻO nā olonā refractory silicate alumini a me nā olonā refractory silicate alumini i manaʻo ʻia: ʻO ka olonā refractory silicate alumini a me ka olonā refractory silicate alumini i manaʻo ʻia he ʻano hou o ka mea refractory a me ka insulation. He olonā inorganic artificial ia i haku ʻia me Al2O3 a me SiO2, i ʻike ʻia hoʻi he fiber ceramic. Loaʻa iā ia ke kūpaʻa ahi kiʻekiʻe a me ka hana insulation maikaʻi. I kēia manawa, hoʻohana ka nui o nā mea hana paila i nā olonā refractory silicate alumini a me nā huahana e like me nā mea hoʻopiha no nā hui hoʻonui a me nā lua ʻē aʻe, e pani ana i nā mea e like me ka asbestos a me nā huahana ʻē aʻe.
Nā waiwai onā olonā paʻakikī silicate aluminia penei kā lākou huahana: ʻo ka nui o nā huahana ma kahi o 150kg/m3; ʻO ka nui o nā olonā ma kahi o (70-90) kg/m3; ʻO ke kū'ē ahi he ≥ 1760 ℃, ʻo ka mahana hana kiʻekiʻe loa ma kahi o 1260 ℃, a ʻo ka mahana hana lōʻihi he 1050 ℃; Ke 200kg/m3 ka nui a ʻo ka mahana hana he 900 ℃, ʻaʻole pono e ʻoi aku ka conductivity thermal o nā olonā a me nā huahana ma mua o 0.128W/(m·k).
