Hoʻolauna iā Diamond a me kāna mau manaʻolana no ka hoʻohana ʻana
I. Nā Manaʻo Kumu o ka Daimana
Daimana ʻo ia kekahi o nā mea paʻakikī loa ma ke ʻano. Hana ʻia ia me ke kalapona i loko o kahi ʻano kristal cubic. Pono ke kūkulu ʻana o ka daimana kūlohelohe i nā mahana a me nā kaomi kiʻekiʻe loa, e hopena ana i nā waihona palena a me nā kumukūʻai mining kiʻekiʻe. Me ka holomua o ka ʻepekema a me ka ʻenehana, ua oʻo mālie ka synthesis o nā daimana artificial, e alakaʻi ana i ka hoʻohana nui ʻana o ka daimana a me kāna micropowder i ka ʻoihana.
I loko o ka mōʻaukala o ka noiʻi kanaka ma nā mea paʻakikī loa, ʻaʻole wale ka daimana he mineral makamae i ka gemology akā he mea hoʻolālā koʻikoʻi hoʻi i ka hana ʻoihana hou. Ma muli o kona mau pono kūikawā i ka paʻakikī, ka conductivity thermal, a me nā waiwai optical, ua kapa ʻia ka daimana ʻo "niho o ka ʻoihana" a me ke "mōʻī o nā mea."
II. Hoʻomākaukau a me ka Hoʻokaʻawale ʻana o ka Daimana
1. Daimana Kūlohelohe
Daimana kūloheloheua loaʻa nui ʻia mai nā waihona kimberlite a me lamprophyre. He palena iki ko lākou hoʻolaha honua, me ʻApelika Hema, Rusia, a me Botswana nā wahi hana nui. Hoʻohana ʻia ka hapa nui o nā daimana kūlohelohe i nā mea hoʻonani, me kahi hapa liʻiliʻi wale nō, ma muli o ko lākou ʻano haʻahaʻa, e hoʻohana ʻia no nā kumu ʻoihana.
2. Nā Daimana Hana ʻia
No ka hoʻokō ʻana i ke koi ʻoihana no nā daimana, ua puka mai ka ʻenehana hana daimana synthetic. ʻO nā ʻano hana synthesis i hoʻohana pinepine ʻia:
Ka Mahana Kiʻekiʻe-Pāomi (HPHT): Hoʻololi ʻia ka graphite i daimana ma lalo o nā kūlana mahana a me ke kaomi kiʻekiʻe. ʻO kēia ke ʻano hana i hoʻohana nui ʻia, kūpono no ka hana ʻana i nā kristal daimana ʻoihana hoʻokahi a me nā pauka maikaʻi.
Ka Hoʻokahe ʻAhu Kemika (CVD): Hoʻokahe ʻia nā kiʻiʻoniʻoni daimana ma ka hoʻohaumia ʻana i nā kinoea hydrocarbon ma lalo o nā kūlana kikoʻī. Hoʻohana nui ʻia kēia ʻano hana i nā mea uila, nā optics, a me nā mea hou.
3. Hoʻokaʻawale ʻana
Hiki ke hoʻokaʻawale nui ʻia nā daimana ma muli o ko lākou ʻano a me ka hoʻohana ʻana:
ʻO nā kristal daimana hoʻokahi: Nā kristal blocky i hoʻohana pinepine ʻia i nā mea hana e like me nā mea ʻokiʻoki, nā make kaha kiʻi uea, a me nā ʻāpana wili.
Pauka daimana maikaʻi: Hana ʻia ma ke kuʻi ʻana a i ʻole ka hoʻokaʻawale maikaʻi ʻana i nā kristal hoʻokahi, hele mai ia i nā ʻano nui like ʻole a hoʻohana nui ʻia no ka wili ʻana a me ka hoʻowali ʻana.
ʻO nā ʻiliʻili lahilahi daimana a me nā composites: Hana ʻia me ka hoʻohana ʻana i ka ʻenehana CVD, hoʻohana nui ʻia lākou i ka hoʻolaha wela, nā puka makani optical, a me nā mea uila.
III. Nā ʻano hana daimana
ʻO ke kūlana o Diamond ma ke ʻano he alakaʻi i waena o nā mea paʻakikī loa e pili ana i kona mau waiwai kino a me ke kemika kūikawā:
Paʻakikī Kiʻekiʻe Loa: Me ka paʻakikī Mohs o 10, ʻo ia ke kiʻekiʻe loa o nā mea i ʻike ʻia, hiki iā ia ke mīkini i aneane nā mea ʻē aʻe.
Ke Alakaʻi Wela Kiʻekiʻe: ʻOi aku ke kiʻekiʻe o ka conductivity wela o ka Daimana ma mua o ke keleawe a me ke kālā, e lilo ia i mea hoʻoheheʻe wela kūpono, kūpono loa no ka hoʻohana ʻana i nā mea uila mana kiʻekiʻe.
Paʻa Kemika Ikaika: ʻAʻohe hopena o ka daimana me nā waikawa a me nā alkalis i ka mahana o ka lumi a me ke kaomi, a loaʻa iā ia ke kūpaʻa maikaʻi loa i ka pala.
Nā Waiwai Optical Maikaʻi Loa: ʻO kona helu kuhikuhi refractive kiʻekiʻe a me ka hoʻoili mālamalama maikaʻi loa e hiki ai ke hoʻohana i nā noi ma nā kahua kukui infrared, ultraviolet, a me nā kukui ʻike ʻia.
Nā Waiwai Uila Hoʻololi: He mea hoʻokaʻawale ka daimana kūlohelohe, akā ma o ka doping, hiki ke hana ʻia i semiconductor, kahi e paʻa ai ka hoʻohiki nui no kona hoʻohana ʻana i nā ʻāpana uila.
IV. Nā Noi Daimana
1. Ka Hana Hana ʻOihana
ʻO ke daimana, ma ke ʻano he mea hoʻopōʻino paʻakikī loa, hoʻohana nui ʻia i ka ʻoki ʻana, ka wili ʻana, a me nā kaʻina hana hoʻopili. Eia kekahi laʻana:
Hoʻohana ʻia nā pahi ʻoki daimana no ka ʻoki ʻana i ka pōhaku;
Hoʻohana ʻia nā huila wili daimana no ka hana ʻana i ka carbide, nā keramika, a me ke aniani optical;
Pauka liʻiliʻi daimanaHoʻohana ʻia e hana i nā slurries abrasive no ka poli pololei ʻana o nā wafers semiconductor a me nā substrates sapphire.
2. Nā Semiconductors a me nā Uila
ʻO nā kiʻiʻoniʻoni daimana CVD, ma muli o ko lākou mau waiwai hoʻoheheʻe wela maikaʻi loa, hoʻohana ʻia e like me nā substrates hoʻoheheʻe wela no nā lasers mana kiʻekiʻe a me nā mea uila mana. Eia kekahi, hōʻike ka daimana doped i nā waiwai semiconductor maikaʻi loa a manaʻo ʻia e hoʻohana ʻia i nā mea uila alapine kiʻekiʻe a me nā voltage kiʻekiʻe.
3. Nā Optics a me nā Kamaʻilio
ʻO ke ʻano moakaka o ka daimana a me ke kūpaʻa ʻana i ka ʻaʻahu e lilo ia i mea kūpono no nā puka makani laser, nā aniani pale ʻike infrared, a me nā aniani optical kikoʻī. I nā ʻōnaehana laser mana kiʻekiʻe a me nā lako optical aerospace, hiki i nā ʻāpana daimana ke hoʻomaikaʻi nui i ka hana a me ke ola.
4. Lapaʻau a me ka Aerospace
ʻO nā mea hana ʻoki daimana, ma muli o ko lākou ʻoi a me ke kūpaʻa, hoʻohana ʻia i nā mea lapaʻau e like me ke ʻoki maka a me ke ʻoki kino minimally invasive. I loko o ka aerospace, he mau noi koʻikoʻi nā kiʻiʻoniʻoni daimana i nā mea ʻike, nā puka makani optical, a me nā uhi pale ʻaʻahu.
5. Kahua Ikehu Hou
Me ka hoʻomohala ʻana o ka ʻoihana photovoltaic a me nā mea ikehu hou, ua koi nui ʻia ka diamond micropowder i nā noi e like me ka ʻoki ʻana i ka wafer silicon a me ka hana ʻana i ka substrate sapphire. Eia kekahi, ʻo kona conductivity thermal kiʻekiʻe e hoʻolilo iā ia i mea pono i ka hoʻokele hoʻoheheʻe wela no nā mea mana i nā kaʻa ikehu hou.
V. Ka Hoʻomohala ʻOihana a me nā ʻAno Kūʻai
Ka Hoʻomau ʻana o ka Ulu ʻana o ka Mākeke
Wahi a nā hōʻike noiʻi ʻoihana, manaʻo ʻia ka waiwai o ka ʻoihana micropowder daimana o Kina e hōʻea i 2.6 biliona yuan i ka makahiki 2025, me ka nui o ka ulu makahiki hui e ʻoi aku ana ma mua o 10%. Ua lilo ʻo Kina i mea hana a me ka mea kūʻai aku nui o ka honua i ka pauka daimana, e helu ana ma kahi o 88% o ka māhele mākeke.
Hoʻolalelale i ka Hana Hou ʻenehana
Ua wehe nā holomua i ka ʻenehana CVD i nā manawa hou no nā noi ʻili lahilahi daimana i nā mea uila a me nā optics. I ka wā e hiki mai ana, e lilo ka hoʻomohala ʻana i nā ʻili daimana maʻemaʻe kiʻekiʻe a nui i mea nui no ka noiʻi.
Ke hoʻonui nei i nā wahi noi
Me ka hoʻomohala ʻana o ka semiconductor, ka ikehu hou, a me nā ʻoihana koa, ua hoʻonui mālie ʻia ka hoʻohana ʻana o ke daimana mai nā abrasives kuʻuna i nā mea uila, aerospace, a me ka hana ʻana kiʻekiʻe, a ke hoʻomau nei ka waiwai o ka ʻoihana e piʻi.
Ke kū mai nei kahi ʻano maopopo i ka hoʻonui ʻia ʻana o ka ʻoihana.
Ke hoʻokumu mālie nei nā ʻoihana kūloko alakaʻi e like me Power Diamond, Huifeng Diamond, a me Yellow River Cyclone i nā ʻano hana hana nui a koʻikoʻi, a ke puka koke mai nei nā hui ʻoihana kūloko (e like me nā mea ma Henan, Anhui, a me Shandong).
VI. Hōʻuluʻulu Manaʻo
Ma ke ʻano he mea paʻakikī loa o ke kūlohelohe, ua lōʻihi ka hoʻohana ʻana o ke daimana ma mua o ka honua pōhaku makamae, e lilo ana i mea nui e kākoʻo ana i ka hana hou a me ka hoʻomohala ʻenehana kiʻekiʻe. Mai ka hana ʻoihana kuʻuna a hiki i nā mea uila holomua, nā optics, ka mālama ʻana i nā lāʻau lapaʻau, a me ka ikehu hou, hōʻike ke daimana i ka waiwai kūlike ʻole.
I ka wā e hiki mai ana, me ka holomua mau ʻana i ka ʻenehana hana daimana hana a me nā kaʻina hana hoʻomākaukau i hoʻomaʻemaʻe ʻia,nā mea daimanae hoʻonui hou aku i kā lākou palena noi a pāʻani i kahi kuleana nui aʻe i nā kahua ʻoi loa e like me nā semiconductors, aerospace, a me ka pale kaua aupuni. He mea hiki ke ʻike mua ʻia ʻaʻole wale ka ʻoihana daimana he holomua nui i ka ʻepekema mea akā he mea nui hoʻi ia o ka hoʻomohala ʻana i ka hana ʻana i nā mea kiʻekiʻe.
