Papa Kūpaʻa Silicon Carbide
Papa hoʻopaʻapaʻa silicon carbideHe papa uhi umu me ke kūpaʻa ahi maikaʻi loa a me ke kūpaʻa ʻana i ka ʻaʻahu. Hoʻohana pinepine ʻia ia i nā wahi hana e lawe a hoʻoili i ka wela a me nā kemika ma lalo o ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe a me nā kūlana pala kemika. Hana nui ʻia nā papa hoʻonohonoho Silicon carbide me nā mea silicon carbide a me silicon nitride, me ka nui o ka nui a me ka mahana kūpaʻa ahi, ka conductivity thermal haʻahaʻa, a ʻaʻole maʻalahi ke hoʻopilikia i ka hoʻolaha mahana o ka hāmeʻa.
Nā Kaʻina Hana:OSiC/SSiC/NSiC/SiC/RBSiC(SiSiC)/RSiC.
Nā Ana/ʻAno:ʻO kēlā me kēia nui (max 1200 × 800mm) a me ke ʻano (huinahā, pōʻai, nā ʻoki kūikawā) ma o ka mīkini CNC.
Hana Lima:E hoʻoponopono i nā mea hoʻopaʻa, nā pōʻaiapuni sintering, a me nā hana ʻili no kāu mau palena hana kikoʻī.
Ma hope o ke kūʻai aku:Kūkākūkā loea, alakaʻi hoʻonohonoho.
Nā Hiʻohiʻona:
Ke kūpaʻa ahi a me ke kūpaʻa ʻana i ka ʻaʻahu:Hiki i nā papa hoʻonohonoho silicon carbide ke hana paʻa ma lalo o ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe a me nā kūlana pala kemika, a he kūpaʻa ahi maikaʻi loa a me ke kūpaʻa ʻana i ka ʻaʻahu.
Hana anti-oxidation:Hiki iā ia ke hana paʻa i ka oxidizing a me ka hoʻemi ʻana i nā lewa, a ʻo ka helu o nā turnovers hiki ke piʻi aʻe ma mua o 500-1000 mau manawa.
Ka ikaika compressive a me ka flexural o ke ana wela kiʻekiʻe:He ikaika kiʻekiʻe kona a he kūpaʻa maikaʻi hoʻi i ka compressive, a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma ke ana wela kiʻekiʻe me ka ʻole o ka deformation.
Ke kū'ē i ka hoʻoluʻu wikiwiki a me ka hoʻomehana ʻana:He kūpaʻa maikaʻi kona i ka hoʻomaʻalili wikiwiki a me ka hoʻomehana ʻana, a ʻaʻole maʻalahi ka haki ʻana i ka wā e hoʻohana ai. Lāʻau ākea o ka mahana hana: hiki ke hoʻohana ʻia ma ka laulā o 800℃-1400℃.
Papa carbide Silicon me ka uhi aluminahiki ke hōʻemi pono i ka ʻaʻahu ʻana o nā mea a hoʻolōʻihi i ke ola lawelawe ma ke kūkulu ʻana i kahi papa pale o ka alumina ma luna o ka silicon carbide. I ka manawa like, hiki i ke kūpaʻa waikawa a me ka alkali o ka alumina ke ālai i ka ʻino ʻana o ka silicon carbide e nā pāpāho waho a hoʻomaikaʻi i ke kūpaʻa ʻana o ka mea. Eia kekahi, he mau waiwai insulation maikaʻi ko ka alumina, hiki ke hoʻokaʻawale i ke kahe ʻana o ke au a i ʻole ka wela a pale i ka nalowale o nā waiwai uila a wela paha.
