Ka hoʻokaʻawale ʻana o nā piliki insulation māmā no nā umu aniani 1

Hiki ke hoʻokaʻawale ʻia nā piliki māmā no nā umu aniani i 6 mau ʻāpana e like me kā lākou mau mea maka like ʻole. ʻO nā mea i hoʻohana nui ʻia, ʻo ia nā piliki silica māmā a me nā piliki diatomite. Loaʻa i nā piliki māmā nā pono o ka hana pale wela maikaʻi, akā ʻo ko lākou kūpaʻa i ke kaomi, ke kūpaʻa i ka slag, a me ke kūpaʻa i ka haʻalulu wela he haʻahaʻa, no laila ʻaʻole hiki iā lākou ke hoʻopili pololei me ke aniani a i ʻole ka lapalapa i hoʻoheheʻe ʻia.

1. Nā piliki silica māmā. ʻO ka piliki insulation silica māmā kahi huahana refractory insulation i hana ʻia mai ka silica ma ke ʻano he mea maka nui, me ka nui o SiO2 ʻaʻole i emi ma mua o 91%. ʻO ka nui o ka piliki insulation silica māmā he 0.9 ~ 1.1g/cm3, a ʻo kona conductivity thermal he hapalua wale nō ia o nā piliki silica maʻamau. Loaʻa iā ia ke kūpaʻa haʻalulu thermal maikaʻi, a hiki i kona mahana palupalu ma lalo o ke kaumaha ke hiki i 1600 ℃, ʻoi aku ka kiʻekiʻe ma mua o nā piliki insulation lepo. No laila, hiki i ka mahana hana kiʻekiʻe loa o nā piliki insulation silica ke hiki i 1550 ℃. ʻAʻole ia e emi i nā mahana kiʻekiʻe, a he hoʻonui iki nō hoʻi. Hana pinepine ʻia ka piliki silica māmā me ka crystalline Quartzite ma ke ʻano he mea maka, a hoʻohui ʻia nā mea hiki ke puhi ʻia e like me ka coke, anthracite, sawdust, a me nā mea ʻē aʻe i loko o nā mea maka e hana i ka ʻano porous a hiki ke hoʻohana ʻia ke ʻano hoʻohua kinoea e hana i ka ʻano porous.
2. Nā piliki Diatomite: Ke hoʻohālikelike ʻia me nā piliki insulation māmā ʻē aʻe, ʻoi aku ka haʻahaʻa o ka conductivity thermal o nā piliki diatomite. ʻOkoʻa kona mahana hana me ka maʻemaʻe. ʻOi aku ka maʻamau o kona mahana hana ma lalo o 1100 ℃ no ka mea he nui ka emi ʻana o ka huahana i nā mahana kiʻekiʻe. Pono e puhi ʻia nā mea maka o nā piliki diatomite i kahi mahana kiʻekiʻe, a hiki ke hoʻololi ʻia ka silicon dioxide i quartz. Hiki ke hoʻohui ʻia ka lime ma ke ʻano he mea hoʻopaʻa a me ka mineralizer e hoʻolaha i ka hoʻololi ʻana o ka quartz i ka wā e puhi ai, he mea maikaʻi ia no ka hoʻomaikaʻi ʻana i ke kūpaʻa wela o ka huahana a me ka hōʻemi ʻana i ka emi ʻana i nā mahana kiʻekiʻe.
ka puke aʻe e hoʻomau mākou i ka hoʻolauna ʻana i ka hoʻokaʻawale ʻana opiliki hoʻokaʻawale māmāno nā umu aniani. E ʻoluʻolu e hoʻolohe mai!
