Hoʻolauna a me ka hoʻopili ʻana o nā abrasives daimana

He mea paʻakikī loa ke daimana ma ke ʻano. Loaʻa iā ia ka paʻakikī kiʻekiʻe loa, ka hoʻokele wela a me ke kūpaʻa ʻana i ka ʻaʻahu, no laila ua hoʻohana nui ʻia ia i ka ʻoihana abrasive. Me ka hoʻomohala ʻana o ka ʻenehana ʻoihana,nā mea hoʻopōʻino daimanaua hoʻomohala ʻia mai nā daimana kūlohelohe kuʻuna i nā daimana hana like ʻole a me nā mea hana hui hana, e lilo ana i ʻāpana koʻikoʻi o ke kahua o nā mea superhard, a ua hoʻohana nui ʻia i nā ʻoihana kiʻekiʻe e like me ka hana ʻana i ka mīkini, nā mea uila, nā optics, a me ka ikehu hou.

Ⅰ. Hoʻolauna kumu o nā abrasives daimana

ʻO nā mea hoʻopailua daimananā mea pauka a granular paha hana ʻia ma ke kuʻi ʻana, ka nānā ʻana, a me ka hoʻomaʻemaʻe ʻana i nā daimana maoli a i ʻole nā ​​daimana hana. ʻO kona paʻakikī Mohs e hiki i ka pae 10, ʻo ia ka mea abrasive i ʻike nui ʻia. Ke hoʻohālikelike ʻia me nā abrasives kuʻuna e like me ka alumini oxide a me ka silicon carbide, ʻoi aku ka kiʻekiʻe o ka hiki ke ʻoki a me ke kūpaʻa ʻana i ka ʻaʻahu ʻana o nā daimana abrasives, a hiki ke wili a hoʻopili i nā mea paʻakikī kiʻekiʻe me ka pono kiʻekiʻe a me ka hōʻino haʻahaʻa.

ʻO nā ʻano abrasives Diamond e komo pū me kēia mau ʻano:

Pauka liʻiliʻi daimanaʻO ka nui o ka ʻāpana mai nā ʻumi microns a i nā nanometers, kūpono no nā kaʻina hana hoʻopili pololei like ʻole.

Huila wili daimana/poʻo wili: hoʻohana ʻia no ka wili ʻana a me ke kālai ʻana i nā mea paʻakikī.

ʻO ka pahi ʻoki daimana/ʻūmiʻi wili: hoʻohana ʻia no ka ʻoki ʻana a me ka wili ʻana i nā mea e like me ka pōhaku, ka keramika, ke aniani, a pēlā aku.

Wai wili daimana/pale wili: hoʻohana nui ʻia i ka hana ʻana i ka pololei loa i nā mea uila, optics, mold a me nā ʻoihana ʻē aʻe.

Mea daimana hui (PCD/PCBN): hoʻohui i ka daimana me ka metala a i ʻole ka matrix keramika e hana i kahi mea hana hui me ka paʻa a me ke kūpaʻa i ka ʻaʻahu.

Ⅱ. Nā kahua noi o nā abrasives daimana

1. Ka hana ʻana i ka mīkini
Hoʻohana nui ʻia nā mea hoʻopōʻino daimana i ke kālai ʻana a me ka wili ʻana i nā mea paʻakikī kiʻekiʻe, e like me ka carbide cemented, keramika, silicon carbide, aniani, ferrite, a pēlā aku. ʻO ka hoʻohana ʻana i nā huila wili daimana no ka hana ʻana ʻaʻole hiki ke hoʻomaikaʻi nui i ka pono o ka hana ʻana a me ka maikaʻi o ka ʻili, akā e hoʻolōʻihi i ke ola o ka mea hana a hōʻemi i ka pinepine o ka hoʻololi ʻana i ka mea hana. He kūpono loa ia no nā kaʻina hana hana kiʻekiʻe i hana nui ʻia, hana ʻakomi.

2. Nā ʻoihana uila a me nā semiconductor
I ka wā o ka hana ʻana i nā mea e like me nā wafers silicon, nā substrates sapphire, nā ʻāpana silicon carbide, ke aniani optoelectronic, a me nā mea ʻē aʻe, nā ʻoki uea daimana, nā wai wili a me nā paʻi polishing nā mea hoʻopau nui. Hiki i nā mea abrasives daimana ke hoʻokō i ka palahalaha a me ka ʻoʻoleʻa submicron a i ʻole ka nanometer-level. Hoʻohana nui ʻia lākou i nā loulou koʻikoʻi e like me ka dicing chip, wili wafer, a me ka polishing photomask. He mea nui lākou i ka hōʻoia ʻana i ka hana kiʻekiʻe a me ka loaʻa kiʻekiʻe o nā huahana uila.

3. Ka hana ʻana i ka ʻike maka
Hoʻohana nui ʻia ka pauka daimana i ka wili ʻana i ke aniani optical, nā puka makani laser, nā aniani sapphire a me nā ʻāpana ʻē aʻe. ʻO kona ikaika ʻoki maikaʻi loa a me ke kūpaʻa kemika hiki ke hoʻomaikaʻi maikaʻi i ka maikaʻi o ka hana aniani a hoʻokō i ka ʻili Ra ma lalo o 10nm. He mea nui ia no ka hoʻokō ʻana i nā ʻili ultra-smooth a me ka transmittance kukui kiʻekiʻe.

4. Ke kūkulu ʻana a me ka hana ʻana i ka pōhaku
Hoʻohana nui ʻia nā pahi ʻoki daimana, nā ʻāpana wili, nā uea ʻoki, a me nā mea ʻē aʻe i ka hana ʻana i nā mea kūkulu hale e like me ka granite, ke kinikini, a me ka sima. Ke hoʻohālikelike ʻia me nā mea hana kuʻuna, ʻoi aku ka maikaʻi o nā mea hana daimana i ka wikiwiki ʻoki, ke ola lawelawe, a me ka maikaʻi o ka ʻoki ʻana, a kūpono loa no ka hana pono ʻana i nā mea kūkulu hale ikaika a kiʻekiʻe.

5. Ikehu hou a me ka aerospace
Me ka hoʻomohala ʻana o ka ʻenehana ikehu hou, ke ulu wikiwiki nei ke koi no nā mea hoʻopōʻino daimana i ka hana ʻana i nā ʻāpana pou pākahiko lithium, nā diaphragms seramika, nā ʻāpana kaʻa uila, a me nā mea ʻē aʻe. Ma ke kahua o ka aerospace, hoʻohana ʻia nā mea hana daimana no ka mīkini pololei o nā ʻāpana wela wela o ka mīkini, nā ʻāpana kūkulu hui, a me nā mea ʻē aʻe, kahi e hoʻomaikaʻi ai i ka hilinaʻi a me ke kūpaʻa o nā huahana.

III. Hopena

ʻO nā mea hoʻopōʻino daimana, ma ke ʻano he mea kumu koʻikoʻi no ka hana ʻoihana hou, ke hoʻohana ʻia nei e nā hiʻohiʻona mīkini kiʻekiʻe aʻe ma muli o ko lākou mau waiwai kino maikaʻi loa a me ka hoʻohana ākea. I ka wā e hiki mai ana, me ka holomua mau o ka ʻepekema mea a me ka ʻenehana hana ʻana, e hoʻomau ka ulu ʻana o nā mea hoʻopōʻino daimana i kahi ala ʻoi aku ka maikaʻi, akamai a me ke aloha i ke kaiapuni, e kōkua ana i ka ʻoihana hana kiʻekiʻe e neʻe i kahi pae kiʻekiʻe.
