Ke ʻimi nei i ka uhi pale ʻaʻahu o nā keramika carbide silicon: he pale paʻa no nā lako ʻoihana.

I ka hana ʻoihana o kēia au, kū pinepine nā lako i nā ʻano hana paʻakikī, a ua lilo ka ʻaʻahu a me ka haehae i mea nui e hoʻopilikia ai i ka pono hana a me nā kumukūʻai.ʻO ka uhi pale ʻaʻahu seramika silikon carbide, ma ke ʻano he mea hana kiʻekiʻe, ke puka mālie mai nei a hāʻawi i nā hopena kūpaʻa maikaʻi loa no nā ʻoihana ʻoihana he nui. I kēia lā, e luʻu kākou i loko o ka uhi kūpaʻa o nā keramika silicon carbide.

1, ʻO ka 'mana nui' o nā keramika silicon carbide
He mau mea hui ʻia nā keramika Silicon carbide (SiC) i haku ʻia me ʻelua mau mea, ʻo silicon a me ke kalapona. ʻOiai kona ʻano maʻalahi, he hana kupaianaha kāna.
1. Pahū ʻana o ka paʻakikī: ʻOi aku ka haʻahaʻa o ka paʻakikī o nā keramika silicon carbide ma mua o ka daimana paʻakikī loa ma ke ʻano. ʻO ke ʻano kēia, hiki iā ia ke pale maʻalahi i ke kahakaha ʻana a me ka ʻoki ʻana o nā ʻāpana paʻakikī like ʻole, a mālama mau i ke kūpaʻa i nā wahi ʻaʻahu kiʻekiʻe, e like me ke kau ʻana i kahi papa o ke kapa kila paʻakikī ma luna o nā lako.
2. Ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa hana ʻana: Me kona paʻakikī kiʻekiʻe loa a me ke ʻano kristal kūikawā, loaʻa i nā keramika silicon carbide ke kūpaʻa ʻaʻahu maikaʻi loa. Ma lalo o nā kūlana ʻaʻahu like, ʻoi aku ka haʻahaʻa o kona helu ʻaʻahu ma mua o nā mea metala kuʻuna, e hoʻolōʻihi nui ana i ke ola lawelawe o nā lako a hoʻemi i ka manawa a me nā poho kumukūʻai i hoʻokumu ʻia e ka hoʻololi pinepine ʻana i nā ʻāpana.
3. Ke kūpaʻa wela kiʻekiʻe: Loaʻa i nā keramika carbide Silicon ke kūpaʻa wela kiʻekiʻe maikaʻi loa a hiki ke hana paʻa no ka manawa lōʻihi ma nā mahana o 1400 ℃ a ʻoi aku paha. ʻO kēia ka mea e hoʻokani ai i kahi kuleana koʻikoʻi i nā kahua ʻoihana wela kiʻekiʻe e like me ka hoʻoheheʻe kila, ka hana mana wela, a pēlā aku. ʻAʻole ia e hoʻololi, palupalu a nalowale paha kāna hana mua ma muli o ke kiʻekiʻe o ka mahana.
4. Paʻa kemika ikaika: Koe wale nō kekahi mau mea e like me ka waikawa hydrofluoric a me ka waikawa phosphoric i hoʻohuihui ʻia, he kūpaʻa ikaika loa nā keramika silicon carbide i ka hapa nui o nā waikawa ikaika, nā kumu ikaika, a me nā metala hoʻoheheʻe like ʻole, a he paʻa loa ko lākou mau waiwai kemika. I nā ʻoihana e like me ke kemika a me ka petroleum, e kū ana i nā ʻano media corrosive like ʻole, hiki iā ia ke pale i nā lako mai ka pala a hōʻoia i ka hana maʻalahi.

2, nā hiʻohiʻona noi o ka silicon carbide ceramic wear-resistant lining
Ma muli o ka hana maikaʻi loa i ʻōlelo ʻia ma luna, ua hoʻohana nui ʻia ka lining pale lole silicon carbide ceramic i nā ʻano ʻoihana like ʻole.
1. Ke ʻeli ʻana: I ka wā o ka lawe ʻana i ka ʻaihao, ʻo nā ʻāpana e like me nā kūlou paipu a me nā chutes he mea maʻalahi loa ia i ka hopena wikiwiki a me ka friction mai nā ʻāpana ʻaihao, e hopena ana i ka ʻaʻahu nui a me ka haehae. Ma hope o ke kau ʻana i ka lining pale ʻaʻahu silicon carbide ceramic, ua hoʻomaikaʻi nui ʻia ke kūpaʻa ʻaʻahu o kēia mau ʻāpana, a hiki ke hoʻolōʻihi ʻia ke ola lawelawe mai kekahi mau mahina a i kekahi mau makahiki, e hōʻemi pono ana i ka nui o nā manawa mālama lako a hoʻomaikaʻi i ka pono hana.
2. ʻOihana mana: Inā paha he ʻōnaehana hoʻokuʻu pauka a me ka ʻōnaehana wehe lehu pneumatic o nā mea kanu mana wela, a i ʻole nā ​​​​​​pahi mīkini koho pauka a me nā liner hoʻokaʻawale cyclone o nā mea kanu sima, ke alo nei lākou a pau i ka nui o ka ʻino lepo a me ke komo ʻana. ʻO ka lining pale ʻaʻahu seramika silicon carbide, me kona kūpaʻa maikaʻi loa i ke komo ʻana, hoʻemi i ka nui o ka ʻaʻahu o nā lako, hoʻolōʻihi i ke ola lawelawe o nā lako, a hoʻemi pū i ka manawa downtime i hoʻokumu ʻia e ka hemahema o nā lako, e hōʻoiaʻiʻo ana i ka hana paʻa o ka mana a me ka hana sima.
3. ʻOihana kemika: Hoʻokomo pinepine ka hana kemika i nā ʻano mea ʻino like ʻole e like me nā waikawa ikaika a me nā alkalis, a hiki i nā lako ke ʻike i nā ʻano like ʻole o ke komo ʻana a me ka haehae i ka wā o ka hana. ʻO ka lining pale ʻaʻahu o ka silicon carbide ceramic he pale ʻaʻahu a pale ʻaʻahu hoʻi, a hiki ke hoʻololi pono i kēia ʻano hana paʻakikī, e hōʻoiaʻiʻo ana i ka hana palekana a me ka pono o nā lako kemika. I nā kūlana e like me ka hana ʻana i nā pila lithium e koi ana i ka maʻemaʻe o nā mea kiʻekiʻe loa, hiki iā ia ke pale aku i ka haumia o ka metala a hōʻoia i ka maikaʻi o ka huahana.
Hāʻawi ka uhi pale ʻaʻahu keramika silikona carbide i ka pale hilinaʻi no nā lako ʻoihana me kāna hana maikaʻi loa, e lilo ana i mea kōkua ikaika no nā ʻoihana he nui e hoʻomaikaʻi i ka pono hana a hoʻemi i nā kumukūʻai. Inā ke kū nei kāu ʻoihana i ka ʻaʻahu a me ka haehae ʻana o nā lako, hiki iā ʻoe ke noʻonoʻo e koho i kā mākou uhi pale ʻaʻahu keramika silicon carbide e hoʻomaka i kahi mokuna hou i ka hana kūpono!
