ʻO ka hoʻohana nui ʻana o ka silicon carbide sintered reaction-sintered a me nā ʻano o nā apo sila

ʻO Silicon nitride (SiC) he one quartz, calcined petroleum coke (a i ʻole coking lanahu), slag lāʻau (no ka hana ʻana o ka silicon nitride ʻōmaʻomaʻo e pono ai ke hoʻohui i ka paʻakai) a me nā mea maka ʻē aʻe, ma o ka umu hoʻomehana uila e hoʻomau ana i ka mahana kiʻekiʻe. ʻO ke apo sila Silicon nitride kahi huahana silicon nitride i hana ʻia me ka mea silicon carbide. No laila he aha nā noi koʻikoʻi o ka silicon carbide sintered reaction a me nā ʻano o nā sila?

ʻO ka hoʻohana nui ʻana o ka hopena sintering silicon carbide:

1. ʻO ka hoʻohana ʻana o ka ʻoihana huahana metala ka hoʻohana ʻana i ke kūpaʻa wela silicon nitride, ikaika kiʻekiʻe, conductivity thermal maikaʻi, kūpaʻa hopena, hoʻomau i ka hoʻomehana ʻana i nā mea maka wela kiʻekiʻe, e like me ka umu haki pahu. ʻO ka pā umu rectifier, ke kelepona electrolytic alumini, ka uhi umu hoʻoheheʻe keleawe, ka arc umu pauka zinc, ka paipu pale thermocouple, a pēlā aku.

2. Hoʻohana ka hoʻohana ʻana o ka ʻoihana kila i ke kālai ʻana o ka silicon nitride. Ke kūpaʻa nei i ka haʻalulu wela, ke kūpaʻa ʻana i ka abrasion. Ma muli o kona conductivity thermal maikaʻi, hoʻohana ʻia no ka uhi ʻana i nā umu hao nui a me ka waena e hoʻonui i ke ola lawelawe.

3. ʻO ka ʻoihana metallurgical concentrator e hoʻohana ana i ka silicon nitride ikaika he lua wale nō ia o ke kila gula, kūpaʻa ikaika i ka ʻaʻahu, kūpaʻa ikaika i ka ʻaʻahu, kūpaʻa kiʻekiʻe o ka pipeline, impeller centrifugal, lumi pamu, mīkini rotary, lining mining lining nā mea maka kūpono, kūpaʻa maikaʻi i ka ʻaʻahu. ʻO ke ola lawelawe o ka plastic he 5 a 20 mau manawa, a ʻo ia kekahi o nā mea maka kūpono no nā kahua haʻuki mokulele.

4. ʻO ka hoʻopili ʻana o ke koina hoʻoili wela i ka pae hana ʻoihana o nā mea hale hoʻonaninani porcelain a me nā ʻāpana huila one. ʻO nā ʻano o ka wela radiant a me ka ikaika wela kiʻekiʻe, ʻo ka hana ʻana a me ka hana ʻana o ka umu metala pepa ʻaʻole hiki ke hōʻemi wale i ka nui o ka umu, akā hoʻomaikaʻi pū i ka nui o ka mālama ʻana a me ka maikaʻi o ka huahana o ka umu, a hoʻemi i ka manawa hana, ʻo ia ka mea kūpono ʻole no ke ahi ʻana o nā pigments seramika.

5. ʻO ka hoʻopili ʻana o ka palekana kaiapuni a me ka pae mālama ikehu he conductivity thermal maikaʻi a me ke kūpaʻa wela, a mālama ka mea hoʻololi wela i 20%, hoʻohana wahie 20%, hoʻohana wahie 35%, a hoʻonui ʻia ka pono hana e 20-30%. Ma ke ʻano kūikawā, ʻo ke kūpaʻa ʻaʻahu o ka paipu hoʻolako wai hoʻokuʻu i hoʻohana ʻia ma ka hale hana hana mining he 6 a 7 mau manawa o nā mea hui metala maʻamau.

Nā hiʻohiʻona o ke apo sila silicon carbide i hoʻopili ʻia:

1, ke kūpale ʻana i ka wela

Ma muli o nā ʻano o nā mea silicon nitride, he kiʻekiʻe ke kūpaʻa o nā sila silicon nitride i ka mahana, a he ʻokoʻa nā ʻano o ke kūpaʻa wela o nā kaʻina hana like ʻole. Hiki ke hoʻopili ʻia nā sila silicon nitride i hoʻopili ʻia me ka hopena mai 1300 degere, a hiki i nā sila silicon nitride i hoʻopaʻa ʻole ʻia ke piʻi i 1600 degere.

2. Ke kūpaʻa ʻana i ka palaho

Hiki ke hoʻopili ʻia ke apo sila silicon nitride mai ke ʻano waikawa ikaika a me ka alkali, a ʻaʻole maʻalahi ka hopena sila e hōʻemi.

3, ke kū'ē'ē ʻana i ke komo ʻana

ʻO nā apo sila silicon carbide i hoʻopili ʻia me ka hopena e like me ke kaʻina hana kāleka, i mea e pololei loa ai ka hoʻolālā a laumania hoʻi, me ka pale ʻana i ke komo ʻana o nā mea silicon carbide, hiki ke hoʻohana ʻia nā apo sila silicon nitride e hamo kekahi i kekahi. ʻAʻole hiki i nā ʻano wela kiʻekiʻe ke hōʻemi maʻalahi i nā ʻano hōʻino.

4. Ka Ductility

ʻOiai aia kekahi ʻenehana hana i hoʻohana ʻia no ka reactivity sintered silicon carbide, hiki ke hoʻololi ʻia i nā ʻano like ʻole o ka embryo hulu hipa a me ka hana lua, e makemake ai nā mea kūʻai aku i nā waiwai.
