Nā Piliki Hoʻokaʻawale Alumina Kiʻekiʻe: He mea nui no nā noi ʻoihana mahana kiʻekiʻe

No nā ʻāpana wela kiʻekiʻe e like me ke kila, ka sima, ke aniani, a me nā petrochemicals, ʻaʻole wale ka insulation hilinaʻi he mea mālama kālā—he ola ia no ka hana ʻana.Nā Piliki Hoʻokaʻawale Alumina Kiʻekiʻe(40%-75% Al₂O₃) e kū nei ma ke ʻano he hopena e pono ai, e hoʻoponopono ana i nā pilikia maʻamau e like me ka nalowale o ka wela, nā hoʻololi pinepine, a me nā hōʻino lako e hoʻopilikia nei i nā mea kuʻuna. ʻO ko lākou maʻalahi ma waena o nā ʻoihana koʻikoʻi e lilo ai lākou i koho kiʻekiʻe no 500+ mau mea hana honua.

ʻOihana kila: Hoʻonui i ka pono a hōʻemi i nā kumukūʻai

ʻO nā wahi ʻino loa o ka hana kila—1500℃ umu pahū, nā ʻōpala kila heheʻe, a me nā umu mālama wela kikoʻī—koi lākou i ka insulation paʻa. Hoʻopili kēia mau piliki i nā ʻau o ka umu pahū, e hōʻemi ana i ka hoʻohana ʻana i ka wahie ma 15%-20% (ua mālama kahi hale wili Kōlea Hema i $50k/makahiki ma ke coke). Mālama lākou i nā ʻōpala mai ka haʻalulu wela, e hōʻoiaʻiʻo ana i ka lawe ʻana i ke kila heheʻe palekana a me ka ʻoki ʻana i ka mālama ʻana ma 50%. I loko o nā tundishes, hoʻemi lākou i nā hemahema hoʻolei ma 8%-12%, ʻoiai i loko o nā umu mālama wela, mālama lākou i ka loli o ka mahana ≤5℃ no ka maikaʻi o ke kila.

Sima a me ke Aniani: Hoʻopaʻa i nā Kaʻina Hana Mahana Kiʻekiʻe

Hoʻololi nā umu sima wili ma waena o nā hoʻomaka anu a me ka hana 1400℃—ke kaumaha e uhaʻi ana i ka insulation nāwaliwali. Kūpaʻa nā pōhaku alumina kiʻekiʻe i kēia mau loli, e hoʻopaʻa ana i nā mahana e hoʻohaʻahaʻa i ka hoʻohana ikehu no kēlā me kēia tona o ka sima ma 8%-12% (ua mālama kahi hale hana Kelemania i €28k/makahiki ma ke kinoea). No nā mea hana aniani, hoʻopili lākou i nā umu hoʻoheheʻe 1450℃, e pale ana i nā pehu a i ʻole ka mānoanoa like ʻole ma ka mālama ʻana i ka wela like. ʻO ko lākou ola 5-8 makahiki (5x ʻoi aku ka lōʻihi ma mua o nā pōhaku alumina haʻahaʻa) ʻo ia hoʻi ka emi ʻana o nā pani no nā pani.

Petrochemical & Power: Kū'ē i ka ʻino a me ke komo ʻana

Ke kū nei nā hale hana petrochemical i ka pala o ka mahu kemika, ʻoiai nā hale hana mana e hana me ka abrasion lehu lele—hoʻopau ʻelua i ka insulation maʻamau. Hoʻopaʻa kēia mau piliki i nā crackers catalytic a me nā pipelines wela kiʻekiʻe, e kūʻē ana i ka pala e hoʻolōʻihi i ke ola o nā lako. ʻO kā lākou hoʻolālā māmā (0.8-1.2 g/cm³) e hoʻomāmā i ka ukana pipeline, a ʻo kā lākou paʻa ʻana i ka wela e hoʻohaʻahaʻa i nā mahana o ka ʻili no nā hana palekana. Ua ʻoki kahi kahua petrochemical US i nā loli insulation pipeline mai 2x/makahiki a i 1x/6 mau makahiki.

No ke aha e koho ai iā mākou?

Hoʻopilikino mākou i nā piliki i kāu mau pono: hoʻoponopono i ka nui o Al₂O₃ (40% no ka mahana waena, 75% no ka wela kiʻekiʻe loa), ka nui, a me ka nui. Hoʻokō nā mea āpau i nā kūlana ASTM/CE/JIS, e hōʻoiaʻiʻo ana i ka hoʻokō honua. E kiʻi i 2-3 mau laʻana manuahi e hoʻāʻo ai, a hāʻawi kā mākou mau ʻenekinia i nā loiloi ma kahi.
