ʻO ka hose rubber alumina ceramic-resistant he huahana paipu ʻoihana i hana ʻia ma ka hoʻohui ʻana i nā tile keramika alumina paʻakikī kiʻekiʻe me kahi matrix rubber flexible ma o ke kaʻina hana vulcanization. ʻO ka keramika alumina i hoʻokomo ʻia (maʻamau me ka ʻike Al₂O₃ o ≥92%) he paʻakikī kiʻekiʻe loa (Rockwell hardness HRA ≥88), e hōʻike ana i ke kūpaʻa ʻana o ka ʻaʻahu ma mua o ʻumi manawa o ka hao i hoʻolei ʻia me ka chromium kiʻekiʻe. Hāʻawi ka papa rubber waho i ka hose me ka maʻalahi maikaʻi loa a me nā waiwai sila, e ʻae ana iā ia e kūlou a omo i nā haʻalulu hopena ma lalo o nā kūlana hana paʻakikī. Hoʻohui maikaʻi kēia hoʻolālā kūkulu i ke kūpaʻa ʻana o ka ʻaʻahu o nā keramika me nā waiwai cushioning o ka rubber, e kūpono ai no ka lawe ʻana i nā media wear kiʻekiʻe i nā ʻoihana e like me ka mining, ka hana mana, a me ka sima.
E pili ana i nā palena hana, ʻokoʻa nā kikoʻī loea o kēia huahana e like me nā koi noi. ʻO ka maʻamau, he ≥3.6 g/cm³ ka nui o ka papa keramika a ʻoi aku ka ikaika kūlou ma mua o 290MPa. ʻOiai hiki iā ia ke kū i nā mahana kiʻekiʻe a hiki i ka 1400°C, ʻo ka mahana hana lōʻihi e kāohi pinepine ʻia ma waena o -30°C a me 150°C i ka hana mau ma muli o nā palena mahana o ka papa laholio. He maʻalahi nā kikoʻī o ka hose, me nā anawaena inoa mai 25mm a 1200mm, nā lōʻihi hoʻokahi a hiki i 20 mika, a me nā pae kaomi hana ma waena o 1MPa a me 4MPa. Eia kekahi, hoʻolālā pinepine ʻia nā tile keramika i nā ʻano hexagonal a i ʻole ka pōʻai a ua hoʻonohonoho pono ʻia a hoʻoulu ʻia e hōʻoia i kahi paia kūloko maʻemaʻe me ke kū'ē wai haʻahaʻa.
Nā hose laholio keramika alumina kūpaʻahoʻohana nui ʻia i nā ʻōnaehana hoʻoili mea kahe multiphase solid-wai-gas multiphase. I loko o nā hale hana mana lanahu, hoʻohana ʻia lākou no ka lawe ʻana o ka lehu lele a me ka lanahu pulverized i ka pneumatic. I ka ʻoihana kila, hoʻohana ʻia lākou no ka hoʻokomo ʻana i ka lanahu pulverized a me ka lawe ʻana i ka hao hao. I ka ʻāpana kemika, me ka hoʻohana ʻana i ke kūpaʻa corrosion o nā keramika, hiki i kēia mau hose ke lawe i nā slurries corrosive e loaʻa ana nā waikawa, alkalis, a me nā paʻakai. Eia kekahi, i ka dredging port a me nā hana pumping sima, ʻo kēia pipeline, me kona mau pono pālua o ke kūpaʻa hopena a me ke kūpaʻa ʻana i ka ʻaʻahu, e hoʻonui nui i ke kaʻina hana mālama a me ke ola lawelawe o ka ʻōnaehana paipu, no laila e hōʻemi ana i nā kumukūʻai hana a me ka mālama holoʻokoʻa.
