Hiki ke hoʻohana ʻia ka ʻenehana uhi silicon carbide ma ke ana wela kiʻekiʻe?

ʻO ka ʻenehana uhi ʻana o Silicon carbide kahi ʻano hana no ka hoʻokumu ʻana i kahi papa silicon carbide ma luna o ka ʻili o nā mea, maʻamau me ka hoʻohana ʻana i ka waiho ʻana o ka mahu kemika, ka waiho ʻana o ka mahu physicochemical, ka impregnation heheʻe, ka hoʻohuihui plasma i ka waiho ʻana o ka mahu kemika a me nā ʻano hana ʻē aʻe e hoʻomākaukau ai i ka uhi silicon carbide, he kūpaʻa kiʻekiʻe ke kūpaʻa o ka uhi silicon carbide, kūpaʻa i ka corrosion, kūpaʻa oxidation, kūpaʻa ʻaʻahu a me nā waiwai maikaʻi ʻē aʻe. No laila, hoʻohana nui ʻia i ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe, nā kaiapuni paʻakikī a me nā kahua ʻē aʻe.

ʻO ke kaiapuni wela kiʻekiʻe kahi kahua koʻikoʻi o ka hoʻohana ʻana i ka uhi ʻana o SIC. Hiki i nā mea kuʻuna ke pilikia i ka hoʻonui ʻia, ka palupalu, ka puhi ʻana, ka oxidation a me nā pilikia ʻē aʻe i ka mahana kiʻekiʻe, akā ʻo ka uhi silicon carbide he kūpaʻa wela kiʻekiʻe a hiki ke kū i ka pala a me ke kaumaha wela i ke kaiapuni wela kiʻekiʻe. No laila, hiki ke hoʻohana i ka ʻenehana uhi SIC i ka mahana kiʻekiʻe.

Ma nā mahana kiʻekiʻe, hiki ke hoʻohana ʻia nā uhi SIC ma nā wahi aʻe:

ʻO ka mea mua, ka mokulele

Hiki i nā ʻenekini lewa hou, nā ʻenekini rocket a me nā lako ʻē aʻe e pono ai ke kū i nā wahi wela a me ke kaomi kiʻekiʻe ke hoʻohana i ka uhi silicon carbide e hāʻawi i nā waiwai wela maikaʻi a me ke kū'ē ʻana i ka ʻaʻahu. Eia kekahi, ma ke kahua o ka lewa nui, ka ʻimi honua, ka satelite, a me nā mea ʻē aʻe, hiki ke hoʻopili ʻia ka uhi silicon carbide e pale i nā lako uila a me nā ʻōnaehana hoʻomalu mai ka radiation wela kiʻekiʻe a me nā kukuna ʻāpana.

ʻO ka lua, ka ikehu hou

Ma ke kikowaena alapine (frequency) nui o ke kelepona, hiki i ka uhi ʻana o ka silicon carbide ke hāʻawi i ka pono hoʻololi kelepona kiʻekiʻe a me ke kūpaʻa maikaʻi, eia kekahi, i hoʻopili ʻia i nā kelepona wahie wela kiʻekiʻe a me nā kahua ʻē aʻe hiki ke hāʻawi i ke ola pākaukau kiʻekiʻe a me ka pono, e hoʻokele ana i ka hoʻomohala ʻana o nā ʻenehana ikehu hou.

3. ʻOihana hao a me ke kila

I loko o ka ʻoihana hao a me ke kila, i ke kaʻina hana hana ma lalo o ke kaiapuni wela kiʻekiʻe, nā piliki umu, nā mea refractory a me nā lako ʻē aʻe a me nā paipu metala, nā valves a me nā ʻāpana ʻē aʻe e pono ai nā mea e kū i ka mahana kiʻekiʻe, ka palaho a me ke komo ʻana, hiki i ka uhi silicon carbide ke hāʻawi i ka hana palekana maikaʻi a hoʻomaikaʻi i ke ola lawelawe o nā lako.

4. ʻOihana Kemika

I ka ʻoihana kemika, hiki i ka hoʻohana ʻana i ka uhi ʻana o ka silicon carbide ke pale i nā lako kemika mai ka pala, ka oxidation a me ka mana o ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe, e hoʻomaikaʻi i ke ola lawelawe a me ka palekana o nā lako. I ka hōʻuluʻulu manaʻo, hiki ke hoʻopili ʻia ka ʻenehana uhi silicon carbide i nā ʻano wela kiʻekiʻe he nui, e hāʻawi i ka hana palekana maikaʻi a me ke ola lawelawe, i ka wā e hiki mai ana, me ka hoʻomohala mau ʻana o ka ʻenehana hoʻomākaukau uhi silicon carbide, e nui aʻe nā kahua o ka hoʻohana ʻana i ka ʻenehana uhi silicon carbide.
