Ma ke kahua o nā mea refractory, corundum, ma ke ʻano he kumu waiwai nui, ua lilo i mea hoʻohana nui ʻia i ka ʻoihana refractory ma muli o kāna mau waiwai kino a me nā kemika. E hōʻike ana kēia ʻatikala i nā hiʻohiʻona kumu, nā noi ākea, ke kūlana mākeke, a me ke kaʻina hana o ka corundum i nā kikoʻī, a e kālele ana i ka mīkini wili kiʻekiʻe 200-mesh corundum e hōʻike iā ʻoe pehea e alakaʻi ai i kahi au hou o ka wili maikaʻi.

ʻO Corundum kahi pōhaku i hana ʻia e ka crystallization o ka alumini oxide. ʻO kona paʻakikī ka lua wale nō i ka daimana a me ka cubic boron nitride, a hiki i kona paʻakikī Mohs i 9. No India mai ka inoa o ka corundum. ʻO Al₂O₃ kona mea nui, a he ʻekolu mau ʻano: α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Ma muli o kāna mau waiwai kino maikaʻi loa, hoʻohana nui ʻia ka corundum i nā mea wili kiʻekiʻe, nā wati, nā mea halihali no nā mīkini pololei, a me nā māla ʻē aʻe.

Ka hoʻohana ʻana i ka corundum

He ākea loa ka laulā noi o corundum, e uhi ana i nā ʻoihana ʻoihana he nui e like me ka metallurgy, mīkini, ʻoihana kemika, uila, mokulele, a me ka pale aupuni. Ma muli o kona kūpaʻa kiʻekiʻe o ka wela, ka pale ʻana i ka corrosion, a me ka ikaika kiʻekiʻe, hoʻohana ʻia ka corundum ma ke ʻano he crucible a me ka moku no ka hoʻolei ʻana i nā puka hoʻoheheʻe kila, ka hoʻoheheʻe ʻana i nā metala makamae loa, a me nā mea hoʻohui kūikawā; i loko o nā ʻōnaehana kemika, hoʻohana ʻia ka corundum e like me nā kīʻaha like ʻole a me nā pipeline a me nā ʻāpana pauma kemika; i loko o ka mechanical field, corundum hoʻohana 'ia e hana i na pahi, molds, bulletproof mea, etc. Eia kekahi, transparent corundum huahana hiki no hoi ke hoʻohana 'ia no ka hana kukui a me microwave fairings, a Na-b-Al₂O₃ huahana mea electrolyte mea no ka hana sodium-sulfur pihi.

Kūlana Kūʻai ʻo Corundum

I nā makahiki i hala iho nei, me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻomohala wikiwiki ʻana o ka ʻoihana, ua hoʻomau ka noi no ka corundum, a ua ākea ka mākeke. ʻO Kina, India, a me Pasila nā mea hana corundum nui o ka honua, a ma waena o Kina ka mea hana nui a me ka mea hoʻopuka i ka corundum keʻokeʻo. Hōʻike ka mākeke corundum i kahi kūlana kaulike ma waena o ka lako a me ka noi, me ka hoʻomaikaʻi mau ʻana o ka huahana a me ka hoʻonui mau ʻana o nā wahi noi. ʻOi aku ma nā kahua kiʻekiʻe e like me ke kiʻekiʻe kiʻekiʻe o ka wili a me ka polishing, ʻoi aku ka nui o ka noi o ka corundum.

ʻO ke kaʻina hana o ka corundum

ʻO ke kaʻina hana o ka corundum e loaʻa i nā ʻanuʻu he nui e like me ka hoʻomākaukau ʻana i nā mea, ka hoʻoheheʻe ʻana, ka hoʻoluʻu, ka crystallization a me ka hana ʻana. ʻO ka mea mua, hoʻomaʻemaʻe ʻia ka pauka alumini oxide kiʻekiʻe a hoʻomaloʻo ʻia e hōʻoia i ka kūlike a me ka maʻemaʻe o nā mea maka. A laila, hoʻokomo ʻia ka pauka alumini oxide i loko o ka umu uila a hoʻomehana ʻia i kahi wela kiʻekiʻe e hoʻoheheʻe ai i loko o kahi kūlana wai. Ma ke ʻano hoʻoheheʻe ʻia, hoʻonohonoho hou nā molekole alumini oxide iā lākou iho e hana i kahi ʻano aniani a hana i nā ʻāpana corundum. A laila, hoʻohaʻahaʻa mālie ʻia ka mahana i hiki i nā ʻāpana corundum e paʻa mālie a paʻa. ʻO ka hope, hoʻomehana hou ʻia e hoʻoikaika i ka hale aniani a hoʻomaikaʻi i ka paʻakikī a me ke kūpaʻa ʻana o ka corundum.

Hoʻolauna o 200 mesh corundum kiʻekiʻe kiʻekiʻe wili mīkini

Ke hoʻohana ʻia ka corundum ma kekahi mau māla, pono e hoʻoheheʻe ʻia i loko o ka pauka maikaʻi 200-mesh ma mua, e like me nā abrasive metala, nā mea aniani seramika, a me nā mea semiconductor optical. ʻO ka hana mua ka wili pinepine. I kēia manawa, pono ʻoe e hoʻohana i ka mīkini wili 200-mesh corundum kiʻekiʻe. ʻO Guilin Hongcheng kahi ʻoihana hoʻoheheʻe nui nui i ka hale R&D a me ka ʻoihana hana. ʻO ka HC series pendulum mill i hoʻomohala ʻia he koho maikaʻi loa ia no ka mīkini wili 200-mesh corundum kiʻekiʻe.

Loaʻa ka HC series swing mill i nā ʻano hiʻohiʻona like ʻole, me nā huahana i kēlā me kēia hola mai ka 1 tons a hiki i ka 50 tons. Paʻa nā mea hana i ka wā i hoʻomaka ai, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana o ka ʻōnaehana puʻuwai maikaʻi, maʻemaʻe a maʻemaʻe ka hale hana, maʻalahi ka mālama ʻana i kēlā me kēia lā, a haʻahaʻa ka uku o ka hana a me ka mālama. Hoʻohana nui ʻia ia i ka ʻoihana refractory a loaʻa ka hana waiwai.

ʻO Guilin Hongcheng 200 mesh corundum kiʻekiʻe-efficiency mīkini wili liʻiliʻi e lilo i mea koʻikoʻi i ke kahua o ka hoʻomaʻamaʻa mineral a me ka hoʻomākaukau ʻana i nā mea ma muli o kona kiʻekiʻe kiʻekiʻe, mālama i ka ikehu a me ka pale o ke kaiapuni. Ma ke ʻano he mea wili kiʻekiʻe kiʻekiʻe, ke hoʻomau nei ka ulu ʻana o ka mākeke no ka corundum a ākea ka mākeke. Welina mai e hoʻokaʻaʻike mai iā mākou no ka ʻōlelo hou.
