Nā Piliki Liner Seramika Alumina i hoʻopaʻa ʻia me ke komo ʻana i ka hana kiʻekiʻe

ʻO nā piliki liner keramika alumina kūpaʻa i ke komo ʻana he hopena pale koʻikoʻi i hana kūikawā ʻia no nā wahi ʻaʻahu kiʻekiʻe e like me nā wili pōpō, nā wili i hoʻoulu ʻia, nā paipu, a me nā chutes. ʻAʻole e like me nā papa uhi pālahalaha kuʻuna, hōʻike kā mākou mau piliki i kahi ʻaoʻao interlocking grooved e hoʻokō ai i kahi hoʻonohonoho paʻa mechanical ma o nā hui alelo-a-groove pololei. Hoʻopau maikaʻi kēia hoʻolālā i nā hakahaka pololei ma waena o nā piliki, e pale ana i ka slurry a me nā ʻāpana liʻiliʻi mai ka hōʻino ʻana i ka pūpū lako. ʻOi aku ka mea nui, hoʻolaha like ia i nā ukana hopena kūloko i nā piliki e pili ana, e hoʻonui nui ana i ke kūpaʻa holoʻokoʻa o ka uhi i ka spalling a me ka haʻalulu mechanical. I hui pū ʻia me nā mea hoʻopili ikaika kiʻekiʻe, hōʻoia ka ʻōnaehana interlocking grooved e paʻa mau ana ka uhi i ka substrate ʻoiai ma lalo o ka wili wikiwiki a i ʻole ka haʻalulu koʻikoʻi, e hāʻawi ana i ka pale mau a lōʻihi.

E pili ana i ka hana o nā mea, hana ʻia kā mākou mau piliki liner alumina keramika mai ka pauka α-alumina maʻemaʻe kiʻekiʻe ma o ke kaomi isostatic a me ka sintering wela kiʻekiʻe loa, me ka nui o ka alumina mai 92% a 99% a hiki ke hoʻopilikino piha ʻia i nā kūlana hana kikoʻī. Ke lawe nei i ka piliki alumina 95% i hoʻohana nui ʻia ma ke ʻano he laʻana, ʻo nā waiwai maʻamau: ka nui o ka nui ≥ 3.65 g/cm³, ka omo wai < 0.01%, ka paʻakikī Rockwell HRA ≥ 86, ka ikaika compressive ≥ 2000 MPa, ka ikaika flexural ≥ 300 MPa, a me ka paʻakikī haki > 3.5 MPa·m½. I nā hoʻokolohua abrasion pulu maʻamau, ʻoi aku ka haʻahaʻa o ka pohō nui ma mua o 90% ma mua o ke kila manganese maʻamau, a ʻo ka nui o ke komo ʻana o ka volumetric ma lalo o 0.02%. ʻAʻole kēia mau helu he mau palena kumumanaʻo akā he ʻikepili nānā maʻamau mai kā mākou ʻōnaehana kaohi maikaʻi koʻikoʻi, e hōʻoiaʻiʻo ana i kēlā me kēia pūʻulu i hāʻawi ʻia e unuhi mau ana i ke kūpaʻa ʻana i ka ʻaʻahu maikaʻi loa, ke kūpaʻa i ka pala, a me ka paʻakikī o ka hopena i ka downtime haʻahaʻa a me ka loaʻa ʻana o nā lako kiʻekiʻe no kā mākou mea kūʻai aku.

I kēia lā, ua hoʻohana nui ʻia kā mākou mau piliki liner alumina interlocked interlocking wear-resistant ma waena o nā ʻoihana mining, sima, hana mana, keramika, a me nā kemika maikaʻi no nā ʻano wili like ʻole a me nā lako lawe. Inā paha e hoʻomanawanui ana i ka holoi ikaika ʻana o nā pōpō kila a me ka slurry i loko o kahi wili hao regrind, e kū ana i ka ʻoki mau ʻana o ka pauka wikiwiki kiʻekiʻe ma nā kuʻekuʻe lawe pneumatic, a i ʻole ke kūʻē ʻana i ka ʻaʻahu corrosive o nā slurries acidic i loko o nā pipelines thickener underflow, hōʻike kēia mau piliki interlocking i kahi ola lawelawe e ʻoi aku ka nui ma mua o nā mea maʻamau.
