ʻO ka Green Silicon Carbide Micropowder: He Benchmark Hou no nā mea hana kiʻekiʻe-Efficiency, Energy-Safety
I. He aha maoli ia? No ke aha i kapa ʻia ai ʻo "Hardcore"?
ʻO ka mea mua, e hoʻomaopopo kākou i ke ahapauka micropoda silicon carbide ʻōmaʻomaʻoʻo ia. E noʻonoʻo iā ia he ʻano "daimana hana." ʻOiai ʻoi aku ka paʻakikī ma mua o ka daimana maoli, he mea hoʻomaʻemaʻe kiʻekiʻe loa ia. Hoʻomaʻemaʻe ʻia i loko o kahi umu pale wela kiʻekiʻe ma luna o 2,000 degere Celsius me ka hoʻohana ʻana i ke one quartz, petroleum coke, a me nā mea maka ʻē aʻe, e loaʻa ana kona kala ʻōmaʻomaʻo kūikawā.
ʻO kona ʻano "hardcore" e hōʻike nui ʻia ana ma nā ʻano ʻekolu:
Paʻakikī Kiʻekiʻe a me ka Lihi ʻOi: ʻO kona paʻakikī Mohs e hōʻea i ka 9.2, ʻo ka lua wale nō ma hope o ke daimana. ʻO ke ʻano kēia, i ka wā e ʻoki ai a wili ai, hana ia e like me ka niho liʻiliʻi a ʻoi, e "wili" maʻalahi ana ma o nā mea paʻakikī a palupalu e like me nā wafers silicon photovoltaic, ke aniani sapphire, a me nā kristal piezoelectric.
Paʻakikī Kiʻekiʻe, Makemake e haki ma mua o ke kūlou: ʻAʻole lawa ka paʻakikī wale nō; pono nō hoʻi ke kūpaʻa. He palupalu loa kekahi mau mea a hiolo i loko o nā pauka maikaʻi ke kaomi ʻia, e hoʻolilo ana iā lākou i mea ʻole. He paʻakikī kiʻekiʻe ka silicon carbide micropowder ʻōmaʻomaʻo me ka mālama ʻana i ka paʻakikī maikaʻi loa. Mālama ia i kona ʻano ma lalo o ke kaomi nui, e hoʻopili pono ana i ka ikaika i ka mea hana me ka ʻole o ka haki ʻana.
Paʻa kemika a hana ikaika: I ka mahana o ka lumi, ʻaʻole ia e pane iki me nā waikawa a i ʻole nā kumu, e lilo ia i mea hana ikaika. ʻO ke ʻano kēia, i ka wā o ke kaʻina hana ʻoki, pale ia i nā hopena kemika i makemake ʻole ʻia me ka mea e hana ʻia ana, e hōʻoia ana i ka maʻemaʻe o ka mea. He mea koʻikoʻi kēia no nā ʻoihana photovoltaic a me semiconductor, kahi i mea nui ai ka maʻemaʻe.
II. Ka pono kiʻekiʻe a me ka mālama ikehu—ʻaʻole ia he mau ʻōlelo lapuwale wale nō
Ke hōʻea nei i ke kumu: No ke aha i kapa ʻia ai he "pae hoʻohālikelike hou"? Pehea e hōʻike kikoʻī ʻia ai kēia mau pono kiʻekiʻe a me ka mālama ʻana i ka ikehu? E ʻoki kākou i nā mea lapuwale a hōʻike i kekahi mau hiʻohiʻona kūpono.
Kūlana 1: ʻO nā "ʻoki kikoʻī" o nā Wafers Silicon Photovoltaic
E Lao Zhang, ua kamaʻāina loa ʻoe i kēia.Mea silikahe pipiʻi loa i kēia mau lā. ʻO ka ʻoki ʻana i ka lahilahi e hua mai i nā wafers hou aʻe, e hōʻemi ana i nā kumukūʻai. Eia nō naʻe, ʻoi aku ka maʻalahi o nā wafers silicon lahilahi i ka haki ʻana, e koi ana i nā kūlana kiʻekiʻe no ka ʻenehana ʻoki a me nā abrasives. ʻO ka micropowder silicon carbide ʻōmaʻomaʻo, me kona ʻano ʻāpana like a me nā ʻaoʻao ʻoi, e hoʻopuka i nā ikaika ʻoki paʻa a like i ka wā o ke kaʻina hana ʻoki. ʻO ka hopena:
Ka pono ʻoki kiʻekiʻe: Hiki ke ʻoki ʻia nā wafers hou aʻe i ka manawa like, a i ʻole hiki ke hoʻonui ʻia ka wikiwiki ʻoki.
ʻAno maikaʻi loa o ka ʻili: He liʻiliʻi ka papa hōʻino o ka ʻili o nā wafers silicon i ʻoki ʻia, a he haʻahaʻa ka TTV (total thickness variation), e hopena ana i ka piʻi wikiwiki ʻana o ka hua.
ʻO ka pohō waiwai haʻahaʻa: ʻO ka ʻoki pololei ʻana e hopena i ka pohō kerf liʻiliʻi, e hōʻemi ana i ka hoʻonele ʻana i nā mea silicon pipiʻi. No nā hoʻopukapuka kālā e ʻoi aku ana ma mua o nā haneli miliona o yuan, he nui kēia mālama kālā.
Kūlana 2: ʻO ka "mea hoʻomanawanui" o ka hana ʻana i ka sapphire
Hana ʻia ka nui o nā uhi kāmela o kāu kelepona a me ke aniani uaki kiʻekiʻe me ka sapeiro. ʻOi aku ka paʻakikī o ka sapeiro ma mua o ke aniani a he mea paʻakikī loa ke hana. ʻO ka hoʻohana ʻana i nā mea abrasives maʻamau hiki ke hoʻomāʻū iā ia ma hope o ka manawa pōkole, e hōʻemi nui ana i ka pono. Eia nō naʻe, ʻo ka silicon carbide micropowder ʻōmaʻomaʻo, mahalo i kona kūpaʻa maikaʻi loa i ka ʻaʻahu ʻana, mālama i kahi ʻoi ʻoi no ka lōʻihi, e hoʻolōʻihi ana i kona ola lawelawe. ʻO ke ʻano kēia:
Ua hoʻemi ʻia ke alapine (frequency) o nā hoʻololi abrasive, ua hoʻopōkole ʻia ka downtime, a ua hoʻomaikaʻi ʻia ka pono o ka hana ʻana.
Ua hoʻemi ʻia nā kumukūʻai hana holoʻokoʻa. ʻOiai paha ke kiʻekiʻe aʻe ke kumukūʻai no kēlā me kēia tona, ʻo ka hoʻonui ʻia o ka pono a me ka hoʻemi ʻia ʻana o nā mea hoʻopau e hōʻemi maoli i ka huina kumukūʻai. He ʻoiaʻiʻo kēia o ka "mālama ikehu."
Kūlana 3: Ke hoʻonui nei i kahi honua ākea
ʻOi aku kona mau hiki ma mua o kēia. ʻO ka hoʻohui ʻana i nā mea refractory holomua hiki ke hoʻolōʻihi i ke ola o nā umu a hoʻomaikaʻi i ka insulation, e mālama pono ana i ka ikehu i loko o nā umu ʻoihana e hoʻohana nui ana i ka ikehu. I loko o nā mea i hui pū ʻia, ma ke ʻano he hoʻoikaika, hana ia i nā ʻāpana i ʻoi aku ka pale ʻana i ke komo ʻana a me ka ikaika, e hoʻolōʻihi ana i nā pōʻaiapuni mālama lako - he ʻano huna hoʻi o ka mālama ikehu. ʻOiai i loko o ka ʻoihana aerospace, he mea pono ia no ka wili pololei ʻana o kekahi mau ʻāpana keramika kūikawā.
III. Ke Alanui i Mua: ʻOi aku ka Maikaʻi, ʻOi aku ka Like, ʻOi aku ka Akamai
ʻOiaʻiʻo, ʻaʻole kūpono ka pauka silicon carbide ʻōmaʻomaʻo. No ka hoʻopaʻa ʻana i kēia "paepae hou," pono kā mākou mea hana e hana me ka ikaika ma nā wahi he nui:
Hoʻomaʻemaʻe mau ʻana i ka nui o nā ʻāpana: Ke koi nei nā ʻoihana ma lalo o ke kahawai i ka pololei kiʻekiʻe. Pono mākou e hana i nā micropowders me ka hoʻolaha nui ʻana o ka nui o nā ʻāpana a me ke ʻano o nā ʻāpana maʻamau (ʻoi aku ka maikaʻi o ka isomorphism). Ua like kēia me kahi hui o nā koa e hele pū ana a neʻe ana i kahi ala hoʻokahi no ka pono kaua kiʻekiʻe loa. Pono e kāohi pono ʻia ka nui o nā ʻāpana nui a me nā ʻāpana liʻiliʻi (ka mea i kapa ʻia ʻo "coarse" a me "fine"); a i ʻole, e hopena ka ʻoki ʻana i nā ʻōpala ma ka ʻāpana hana a me ka emi ʻana o ka pono.
Ke akamai o ka hoʻololi ʻana i ka ʻili: Hoʻololi ʻana i ka ʻili onā ʻāpana pauka liʻiliʻihe hana loea loa ia. No ka laʻana, ʻo ka hoʻonui ʻana i ko lākou kūlike me nā wai ʻoki a me nā mea hoʻopaʻa resin hiki ke hoʻonui hou aku i ka pono o ka ʻoki ʻana a me ka hana huahana. Ua like ia me ka ʻaila ʻana i ka pahi kaua—ʻaʻole ia e hoʻokala wale i kona maka akā hoʻonui pū i kona kūpaʻa.
Ke Hoʻomaʻemaʻe ʻana i ke Kaʻina Hana: ʻOiai he mea mālama ikehu ia, hiki i kāna kaʻina hana ke ʻoi aku ka maikaʻi o ka ikehu a me ka launa pū me ke kaiapuni? No ka laʻana, ka hoʻohana ʻana i ka ikehu i nā umu hoʻoheheʻe, ka hōʻiliʻili lepo i ka wā e kuʻi ai a me ka kānana ʻana, a me ka hana hou ʻana i ka wai—nā wahi āpau e pono ai nā hoʻomaikaʻi mau a me nā hana hou i loko o kā mākou ʻoihana. Ke hoʻoikaika nei mākou e hana i nā mea ʻōmaʻomaʻo ma o ko lākou ola holoʻokoʻa.
No mākou i loko o ka ʻoihana mea hana, ua hoʻomaka wale ka moʻolelo o ka micropowder silicon carbide ʻōmaʻomaʻo. ʻO ka hoʻomaikaʻi ʻana iā ia, kikoʻī, a akamai hoʻi kā mākou hāʻawi nui loa i ka hoʻokele ʻana i ka hana kiʻekiʻe o Kina i ka pono a me ka mālama ʻana i ka ikehu.
