Ma nā ʻano he nui o ka hana ʻoihana, ʻo ka hoʻohana ʻana i nā lako a me ka haehae ʻana he kumu nui ia e hoʻopilikia ai i ka pono o ka hana a me ke kumukūʻai. I mea e hoʻoponopono ai i kēia pilikia, ua puka mai nā ʻano mea like ʻole e kūʻē i ke komo ʻana, a ma waena o ia mau mea ua lilo mālie ka lining pale i ke komo ʻana o ka silicon carbide i "punahele hou" ma ke kahua ʻoihana ma muli o kāna hana maikaʻi loa. I kēia lā, e luʻu kākou i loko o kēia mea kilokilo.
1. He aha ka meaka uhi pale ʻaʻahu silicon carbide?
ʻO ka Silicon carbide (SiC) kahi hui i haku ʻia me ka silicon a me ke kalapona, me kahi ʻano kristal kū hoʻokahi a paʻa. ʻO kona mau ʻāpana hoʻonohonoho kumu he SiC a me CSi tetrahedra i ulana ʻia. ʻO ka uhi pale ʻaʻahu Silicon carbide kahi papa pale i hana ʻia me ka mea silicon carbide e pale i loko o nā lako mai ka ʻaʻahu a me ka haehae. Hiki ke hana ʻia i nā ʻano like ʻole, e like me nā apo keramika, nā liner keramika, a pēlā aku, a laila hoʻokomo ʻia ma nā paia o loko o nā lako e like me nā pipelines, nā kino pamu, a me nā silos i maʻalahi i ka ʻino a me ka friction.
2, Nā pono o ka uhi pale ʻaʻahu silicon carbide
1. Paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu nui: ʻOi aku ka paʻakikī o nā keramika silicon carbide, ʻo ka lua wale nō ma hope o ka daimana paʻakikī loa ma ke ʻano. Hāʻawi kēia paʻakikī kiʻekiʻe iā ia i ke kūpaʻa ʻana i ka ʻaʻahu ikaika loa, hiki ke kū i ka ʻino wikiwiki a me ka friction ikaika o nā mea, e hoʻolōʻihi nui ana i ke ola lawelawe o nā lako, e lilo ia i mea kūpono i ke kūpaʻa ʻaʻahu i ke kahua o ke kapa kaumaha. Ke hoʻohālikelike ʻia me nā mea maʻamau ʻē aʻe, he mau pono koʻikoʻi ka lining pale ʻaʻahu silicon carbide i ke kūpaʻa ʻaʻahu, hiki ke hōʻemi i ke alapine o ka mālama ʻana i nā lako a me ka hoʻololi ʻana no nā ʻoihana a hoʻemi i nā kumukūʻai hana.
2. Haʻahaʻa ka nui a me ke kaumaha māmā: ʻOi aku ka haʻahaʻa o ka nui o ka Silicon carbide ma mua o nā metala e like me ke kila. No ka laʻana, ʻo ka nui o nā keramika silicon carbide sintered reaction he 3.0g/cm³ wale nō, ʻoiai ʻo ka nui o nā keramika silicon carbide sintered pressureless he 3.14-3.0g/cm³. I ke ʻano o ka nui like, ʻoi aku ka māmā o ke kaumaha o ka lining pale-ʻaʻahu silicon carbide, ʻaʻole ia e hoʻomaʻalahi wale i ka lawe ʻana a me ke kau ʻana, akā e hōʻemi pū ana hoʻi i ka ukana mechanical o nā lako, e maʻalahi ai ka hana o nā lako, a hiki ke hoʻokomo i nā pipeline a me nā lako ʻē aʻe i kiʻekiʻe a mamao aku.
3. Ke kūpaʻa wela kiʻekiʻe: Loaʻa iā ia ke kūpaʻa wela maikaʻi a ʻo ke ʻano kristal kūikawā o ka silicon carbide e hiki ai iā ia ke kū i nā mahana kiʻekiʻe, me ka mahana sintering a hiki i ka 1350 ℃. ʻO kēia ʻano e hiki ai i ka lining pale-ʻaʻahu silicon carbide ke mālama i ka hana paʻa ʻoiai ma nā wahi wela kiʻekiʻe, me ka ʻole o ka deformation a i ʻole ka hōʻino ʻia ma muli o nā mahana kiʻekiʻe, e kūpono ai no nā ʻano ʻoihana wela kiʻekiʻe e like me ka metallurgy, ka mana a me nā ʻoihana ʻē aʻe.
4. Ke kūpaʻa ʻana i ka palaho: Loaʻa i ka Silicon carbide nā waiwai kemika paʻa a hiki ke hōʻike i ke kūpaʻa maikaʻi i ka palaho i ke alo o nā mea kemika like ʻole. Inā paha i ka lawe ʻana i nā media waikawa ikaika a me ka alkaline i ka hana kemika a i ʻole ke kahua o ka palekana kaiapuni e like me ka mālama ʻana i ka wai ʻino, hiki i ka lining pale-pale silicon carbide ke pale pono i nā lako, pale i nā lako mai ka palaho ʻia e nā mea kemika, a hoʻolōʻihi i ke ola lawelawe o nā lako.
5. Ka conductivity nāwaliwali a me ka anti-static: He palupalu ka conductivity o nā keramika carbide Silicon, kahi e kūpono ai lākou no nā noi me nā koi koʻikoʻi no ka uila static, e like me nā hale hana pale pahū. I loko o kēia mau wahi, hiki i ka uila static ke hana i nā ulia palekana koʻikoʻi, a ʻo ka hana anti-static o ka lining pale lole silicon carbide hiki ke pale pono i ka hōʻiliʻili ʻana o ka uila static a hōʻoia i ka palekana hana.
6. Maʻalahi ke hana, hiki ke hana i nā ʻāpana nui a paʻakikī: Hiki ke hana ʻia ka Silicon carbide me ka hoʻohana ʻana i nā kaʻina hana e like me ka reaction sintering, kahi e hāʻawi ai i nā pono nui i ke kūkulu ʻana. Ma o kēia kaʻina hana, hiki ke hana ʻia nā keramika nui a me nā keramika i hoʻonohonoho ʻia me ke ʻano paʻakikī. ʻO ke ʻano kēia, ʻaʻohe mea pehea ke ʻano kūikawā a me ka nui o nā lako, hiki ke hoʻololi maikaʻi ʻia ka lining pale ʻaʻahu silicon carbide e hoʻokō i nā pono o nā lako ʻoihana like ʻole.
Ua hōʻike ka uhi pale ʻaʻahu silicon carbide i ka waiwai nui o ka hoʻohana ʻana ma ke kahua ʻoihana ma muli o kona mau pono he nui. Me ka hoʻomohala mau ʻana a me ka holomua o ka ʻepekema mea, ua manaʻoʻiʻo ʻia e hoʻopili ʻia ka uhi pale ʻaʻahu silicon carbide ma nā kahua he nui, e hāʻawi ana i ke kākoʻo ikaika no ka hana pono a paʻa o ka hana ʻoihana. Inā makemake ʻoe i ka uhi pale ʻaʻahu silicon carbide, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa e ʻimi i nā mea huna hou aʻe e pili ana i nā keramika silicon carbide.
