Ka hoʻokaʻawale ʻana o nā pōhaku lepo māmā no nā kiln aniani 1

Hiki ke hoʻokaʻawale ʻia nā pōhaku lepo māmā no nā kīʻaha aniani i 6 mau ʻāpana e like me kā lākou mau mea maka. ʻO nā mea i hoʻohana nuiʻia he mau pōhaku silica māmā a me nā pōhaku lepo diatomite. Loaʻa i nā pōhaku lepo māmā nā mea maikaʻi o ka hana insulation wela maikaʻi, akā maikaʻi ko lākou pale ʻana i ke kaomi, pale ʻana i ka slag, a me ke kūpaʻa haʻalulu wela, no laila ʻaʻole hiki iā lākou ke hoʻopili pololei me ke aniani hoʻoheheʻe a i ʻole ke ahi.

1. Nā pōhaku lepo silica māmā. ʻO ka brick insulation silica māmā he huahana refractory insulation i hana ʻia mai ka silica ma ke ʻano he kumu waiwai nui, me ka ʻike SiO2 ʻaʻole i emi iho ma mua o 91%. ʻO 0.9 ~ 1.1g/cm3 ka mānoanoa o ka silica insulation brick māmā, a ʻo kona conductivity thermal he hapalua wale nō ia o nā pōhaku silica maʻamau. Loaʻa iā ia ke kūpaʻa haʻalulu maikaʻi, a ʻo kona mahana palupalu ma lalo o ka ukana hiki ke hiki i 1600 ℃, ʻoi aku ka kiʻekiʻe ma mua o nā pōhaku lepo insulation. No laila, hiki ke piʻi i ka 1550 ℃ ke kiʻekiʻe o ka hana o ka silica insulation bricks. ʻAʻole ia e emi i nā wela kiʻekiʻe, a hiki ke hoʻonui iki. Hoʻohana pinepine ʻia nā pōhaku silica māmā me ka crystalline Quartzite ma ke ʻano he kumu, a ua hoʻohui ʻia nā mea puhi e like me ka coke, anthracite, sawdust, etc.
2. Nā pōhaku lepo diatomite: Ke hoʻohālikelike ʻia me nā pōhaku lepo māmā ʻē aʻe, ʻoi aku ka haʻahaʻa o ka conductivity thermal o nā pōhaku diatomite. ʻOkoʻa kona mahana hana me ka maʻemaʻe. ʻO ka mahana hana ma lalo o 1100 ℃ no ka mea ʻoi aku ka nui o ka emi ʻana o ka huahana i nā wela kiʻekiʻe. Pono e puhi ʻia nā mea maka o ka diatomite brick i kahi wela kiʻekiʻe, a hiki ke hoʻololi ʻia ka silicon dioxide i quartz. Hiki ke hoʻohui pū ʻia ka lime ma ke ʻano he mea hoʻopaʻa a me ka mineralizer e hoʻoikaika i ka hoʻololi ʻana o ka quartz i ka wā o ke puhi ʻana, he mea maikaʻi ia no ka hoʻomaikaʻi ʻana i ka pale wela o ka huahana a hoʻemi i ka shrinkage i nā wela kiʻekiʻe.
ʻO ka puke aʻe e hoʻomau mākou i ka hoʻolauna ʻana i ka hoʻonohonoho ʻana opōhaku lepo māmāno na kiln aniani. E ʻoluʻolu e hoʻomau!
