Nā paipu liner keramika alumina kūpaʻa ʻolehe ʻāpana pale koʻikoʻi i hoʻohana nui ʻia i nā ʻōnaehana paipu ʻoihana i loaʻa i ka abrasion koʻikoʻi. ʻO kā lākou ʻano mua he alpha-alumina (Al₂O₃), me ka ʻike maʻamau mai 92% a 99.5%. Hana ʻia kēia mea ma o kahi kaʻina hana sintering wela kiʻekiʻe, e hopena ana i ka paʻakikī koʻikoʻi, me ka paʻakikī Rockwell (HRA) o ≥85 a me ka helu paʻakikī Mohs o 9, ʻo ka lua wale nō i ka daimana. Hoʻopaʻa paʻa ʻia kēia mau paipu liner a i ʻole i hoʻokomo ʻia ma ka mīkini ma ka paia o loko o nā paipu metala, e hana ana i kahi pale pale paʻa e hoʻokaʻawale pono i ke kahe ʻana o ka wai mai ka holoi pololei ʻana a me ke komo ʻana ma ke kino paipu metala.
ʻO kā lākou hana kiʻekiʻe loa mai nā waiwai kūlohelohe o nā keramika alumina. Ma waho aʻe o ka paʻakikī kiʻekiʻe, ʻo ko lākou density maʻamau he >3.6 g/cm³, me ka ikaika compressive e ʻoi aku ana ma mua o 850 MPa. ʻO ke kūpaʻa ʻana o kēia mau liners keramika ma kahi o 266 mau manawa o ke kila manganese a me 171.5 mau manawa o ka hao i hoʻolei ʻia me ka chromium kiʻekiʻe, e hoʻolōʻihi ana i ke ola lawelawe o nā lako ma 5 a 10 mau manawa ma lalo o nā kūlana hana like. ʻO ko lākou ʻili laumania a me ka coefficient haʻahaʻa o ka friction e hōʻemi pono i ke kūpaʻa lawe. Loaʻa iā lākou ke kūpaʻa corrosion maikaʻi loa, e kū ana i ka hapa nui o nā media kemika koe wale nō ka waikawa hydrofluoric a me nā alkalis wela i hoʻopaʻa ʻia.
Hoʻohana nui ʻia kēia huahana ma nā ʻāpana ʻoihana me nā koi koʻikoʻi no ke kūpaʻa ʻana i ka ʻaʻahu. ʻO nā noi maʻamau e pili ana i ka lawe ʻana i ka lanahu, ka hānai wahie i pulverized, a me nā ʻōnaehana wehe lehu i nā hale hana mana wela; nā paipu lawe lanahu a me ka pauka ore i pulverized i nā hale wili kila; nā laina hoʻoili palaoa maka, clinker, a me ka pauka lanahu i nā hale hana sima; a me nā ʻōnaehana lawe ʻana i nā tailings a me ka slurry concentrate i nā hana mining. Hoʻohana nui ʻia ia i nā paipu lawe pneumatic a me hydraulic i nā ʻoihana metallurgical, kemika, a me nā ʻoihana ʻē aʻe, e hoʻoponopono pono ana i nā pilikia o ka ʻaʻahu wikiwiki ʻana o ka pipeline, perforation, a me ka leakage i hoʻokumu ʻia e ka holoi ʻana i nā mea lōʻihi.
I ka hōʻuluʻulu manaʻo, hāʻawi nā paipu laina keramika alumina kūpaʻa i ka pale lōʻihi no nā paipu lawe ʻoihana ma o ko lākou paʻakikī kiʻekiʻe loa, ka ʻaʻahu kūikawā, a me ke kūpaʻa i ka pala. Hoʻemi nui lākou i ke alapine o ka pani ʻana no nā kumukūʻai mālama a me ka hoʻololi i hoʻokumu ʻia e ka ʻaʻahu ʻana o ka paipu, e hoʻonui ana i ka pono hana mau a me ka palekana o nā ʻōnaehana hana. Hōʻike lākou i kahi hopena pale i hōʻoia ʻia a kūpono hoʻi.
