ʻO nā mea hoʻoliʻiliʻi a me ka wili o Nano Silicon Carbide

Nano Silicon carbide pauda(HW-D507) hana ʻia e ka hoʻoheheʻe ʻana i ke one quartz, ka petroleum coke (a i ʻole ka lanahu coke), a me nā ʻāpana lāʻau e like me nā mea maka ma o ka wela kiʻekiʻe i nā kapuahi pale. Loaʻa ka silikoni carbide ma ke ʻano ma ke ʻano he mineral kakaʻikahi - i kapa ʻia he moissanite. I loko o ka ʻenehana kiʻekiʻe refractory maka mea e like me C, N, B a me nā mea ʻole oxide, silicon carbide ka mea i hoʻohana nui ʻia a ʻoi aku ka waiwai.

β-SiC paudaloaʻa nā waiwai e like me ke kūpaʻa kemika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka conductivity thermal kiʻekiʻe, ka coefficient hoʻonui wela haʻahaʻa a pēlā aku. No laila, loaʻa iā ia nā hana maikaʻi loa e like me ka anti-abrasion, ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa haʻalulu wela. Hiki ke hana ʻia ka silikoni carbide i nā pauka abrasive a i ʻole nā ​​​​poʻo wili no ka wili kiʻekiʻe a me ka polishing o nā mea e like me nā metala, keramika, aniani a me nā plastics. Hoʻohālikelike ʻia me nā mea abrasive kuʻuna, ʻo SiC ke kūpaʻa ʻaʻahu kiʻekiʻe, ka paʻakikī a me ke kūpaʻa wela, hiki ke hoʻomaikaʻi maikaʻi i ka hoʻoili ʻana i ka pololei a me ka pono. Eia kekahi, loaʻa iā ia ke kūpaʻa kemika maikaʻi a me ke kūpaʻa wela kiʻekiʻe, no laila he ākea ka nui o nā manaʻo noi ma nā ʻano like ʻole.

Hiki ke hoʻohana ʻia ʻo SiC no ka hoʻomākaukau ʻana i nā mea polishing, nona ka nui o nā noi i ka ʻenekinia mechanical, nā mea uila, nā mea optical a me nā māla ʻē aʻe. Loaʻa i kēia mea polishing nā waiwai maikaʻi e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me ke kūpaʻa kemika kiʻekiʻe, hiki ke hoʻokō i nā hana polishing kiʻekiʻe a me ka wili. I kēia manawa, he daimana ka mea wili a me ka polishing nui ma ka mākeke, a ʻo kāna kumukūʻai he ʻumi a i ʻole haneli mau manawa o β-Sic. Eia nō naʻe, ʻaʻole i emi iki ka hopena wili o β-Sic ma nā kula he nui ma mua o ke daimana. Ke hoʻohālikelike ʻia me nā abrasive ʻē aʻe o ka nui o ka nui like, ʻo β-Sic ka mea kiʻekiʻe loa o ka hana ʻana a me ka hana kumu kūʻai.

Ma ke ʻano he mea polishing a me ka wili ʻana, ʻo ka nano silicon carbide ka maikaʻi haʻahaʻa haʻahaʻa haʻahaʻa a me nā waiwai optical maikaʻi loa, i hoʻohana nui ʻia i ka hana microelectronic a me ka hana optoelectronic. Hiki i ka Nano silicon carbide polishing a me ka wili ʻana i nā mea hiki ke hoʻokō i nā mana polishing kiʻekiʻe loa, ʻoiai ke kāohi ʻana a me ka hōʻemi ʻana i ka ʻili a me ka morphology, e hoʻomaikaʻi i ka maikaʻi o ka ʻili o ka mea a me ka hana o ka huahana.

I loko o nā mea hana daimana resin, nano silicon carbide he mea hoʻohui koʻikoʻi e hiki ai ke hoʻomaikaʻi maikaʻi i ka pale ʻana i ka lole, ʻokiʻoki a me ka hana polishing o nā mea hana daimana resin-based. I kēia manawa, hiki i ka liʻiliʻi liʻiliʻi a me ka hoʻopuehu maikaʻi ʻana o SiC hiki ke hoʻomaikaʻi i ka hana ʻana o nā mea hana daimana resin-based ma o ka hui ʻana me nā mea resin-based. He maʻalahi a maʻalahi ke kaʻina hana o ka nano SiC no ka hana ʻana i nā mea hana daimana resin-based. ʻO ka mea mua, ua hui pū ʻia ka pauka nano SiC me ka pauka resin i kahi ratio i koho mua ʻia, a laila hoʻomehana ʻia a kaomi ʻia i loko o kahi ʻōpala, hiki ke hoʻopau pono i ka hāʻawi ʻole ʻana o nā ʻāpana daimana ma o ka hoʻohana ʻana i ka waiwai dispersion like ʻole o SiC nanoparticles, no laila e hoʻomaikaʻi nui ai i ka ikaika a paʻakikī o nā mea hana a hoʻonui i ko lākou ola lawelawe.

Ma waho aʻe o ka hana ʻana i nā mea hana daimana resin-based,nanoparticles carbide silikahiki ke hoʻohana ʻia i ka hana ʻana i nā ʻano abrasives a me nā mea hana hana, e like me ka wili ʻana i nā huila, ke one, nā mea polishing, a me nā mea ʻē aʻe. Me ka hoʻonui nui ʻana o nā ʻoihana like ʻole e hoʻohana i nā mea hana kiʻekiʻe a me nā mea hana kiʻekiʻe kiʻekiʻe a me nā abrasives, ʻoiaʻiʻo e hoʻopuka ʻo nano silicon carbide i nā noi nui aʻe i kēia mau kahua.

I ka hopena, ua loaʻa i ka nano silicon carbide pauka ka manaʻo noiʻi ākea e like me kahi mea polishing kiʻekiʻe. Me ka holomua mau o ka ʻepekema a me ka ʻenehana, nano silicon carbide a me resin-based diamond tools e hoʻomaikaʻi mau ʻia a hoʻonui ʻia i kahi ākea o nā māla.

He mea hana ʻoihana ʻo Hongwu Nano i nā pauka metala makamae nano a me kā lākou mau oxides, me ka maikaʻi o ka huahana paʻa a me ke kumu kūʻai maikaʻi loa. Hāʻawi ʻo Hongwu Nano i ka SiC nanopowder. Welina mai e leka uila iā mākou no ka ʻike hou aku.
