Nā Palena Hana a me nā Noi o nā Tile Ceramic Alumina e kūʻē i ke kapa komo

Nā kile keramika alumina kūpaʻahe mau huahana keramika hana i hana ʻia mai ka alumini oxide maʻemaʻe kiʻekiʻe (Al₂O₃) ma o ke kaomi ʻana a me ka sintering wela kiʻekiʻe. ʻO kā lākou ʻike Al₂O₃ he 92%, 95%, a i ʻole 99%, me ka nui mai 3.60 g/cm³ a ​​i 3.90 g/cm³ a ​​me ka omo wai ma lalo o 0.01%. Hōʻike ka mea i ka paʻakikī kiʻekiʻe a me ke kūpaʻa kemika maikaʻi, kūpono no nā hiʻohiʻona ʻoihana e pili ana i ka hopena, ka friction paheʻe, a me nā media corrosive.

Nā palena hana maʻamau: ʻO ka paʻakikī Mohs o 9, ʻo ka paʻakikī Rockwell HRA 85-90, a me ke kūpaʻa ʻana i ka ʻaʻahu he 20-30 mau manawa ma mua o ke kila kalapona maʻamau (ʻo ka nui o ka ʻaʻahu ≤0.05 cm³ no ka hoʻāʻo huila one maloʻo ASTM G65). Hiki i ka ikaika flexural i 250-350 MPa, ʻo ka conductivity thermal ma kahi o 25-30 W/(m·K), a me ka pae mahana hana mai -50 °C a i 1200 °C (ma muli o ke ʻano kikoʻī). Hōʻoia kēia mau ʻikepili i ka hilinaʻi lōʻihi ma lalo o nā kūlana ʻaʻahu kiʻekiʻe a me nā mahana kiʻekiʻe.

Hoʻohana nui ʻia ka huahana no ka pale ʻana i ka ʻaʻahu ʻana i nā lako koʻikoʻi ma waena o ka sima, ke kila, ka mana, ka eli ʻana, a me nā ʻoihana lanahu, e like me nā pahi classifier, nā chutes, nā kuʻekuʻe paipu, nā cyclones, a me nā lining hopper. ʻO nā ʻano hoʻonohonoho e komo pū me ka epoxy resin bonding, bolting, a i ʻole ka welding (me ka hoʻohana ʻana i nā tile seramika i wili mua ʻia me nā papa rubber/kila). ʻO ka mānoanoa maʻamau mai 5 mm a 25 mm; ʻo nā nui tile maʻamau e komo pū me 10 mm × 10 mm, 20 mm × 20 mm, a me 50 mm × 50 mm square a i ʻole hexagonal no ka ʻoki maʻalahi a me ka hoʻonohonoho ʻana ma kahi.

ʻO ka hoʻohana ʻana i nā tile keramika alumina pale ʻaʻahu e hoʻolōʻihi nui i ke ola lawelawe o nā lako a hoʻemi i ka manawa hana no ka mālama ʻana. Hōʻike ka ʻikepili kahua ma lalo o nā kūlana hana like, ʻoi aku ka lōʻihi o ka mau ʻana o nā uhi keramika ma mua o ke kila manganese kiʻekiʻe a i ʻole nā ​​​​papa kila alloy pale ʻaʻahu. ʻAʻole magnetic ka huahana, kūpaʻa i ka corrosion acid/alkali (koe wale nō ka waikawa hydrofluoric a me ka alkali i hoʻohuihui ʻia), a ʻaʻole ia e haumia i nā mea. Pono ke koho e hoʻoholo i ka ʻike Al₂O₃ a me ka mānoanoa o ka tile e pili ana i ke kihi hopena maoli, ka nui o ka ʻāpana, a me ka mahana e hoʻokō ai i ke kaulike ma waena o ka hana a me ke kumukūʻai.
