ʻO ka uhi ʻana o ka pamu slurry silicon carbide: kahi koho kūpono no ka halihali ʻoihana

I nā hiʻohiʻona hana ʻoihana he nui, pono pinepine ka lawe ʻana i nā wai i loaʻa nā ʻāpana paʻa, a mākou e kapa nei he slurry. He mea maʻamau loa kēia koi i nā ʻoihana e like me ka mining, metallurgy, mana, a me ka ʻenekinia kemika. A ʻo kapamu slurryʻo ia nā lako koʻikoʻi e kuleana no ka lawe ʻana i nā hana. Ma waena o nā ʻāpana he nui o ka pamu slurry, he kuleana koʻikoʻi ka lining no ka mea e pili pono ana ia i ka slurry. ʻAʻole ia e pale wale i ka ʻino a me ke komo ʻana o nā ʻāpana paʻa i loko o ka slurry, akā e kū pū ana hoʻi i ka pala o nā mea kemika like ʻole. He ʻino loa ke kaiapuni hana.
ʻO nā mea uhi kuʻuna no nā pamu slurry, e like me ka metala a me ka laholio, he mau hemahema pinepine kekahi i ka wā e kū nei i nā kūlana hana paʻakikī. ʻOiai he ikaika kiʻekiʻe ka uhi metala, ua kaupalena ʻia kona kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa ʻana i ka pala. Hiki i ka hoʻohana lōʻihi ke alakaʻi maʻalahi i ka ʻaʻahu a me ka pala, e hopena ana i ka mālama pinepine ʻana i nā lako a me ke ola lawelawe pōkole. He maikaʻi ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa ʻana i ka pala o ka uhi laholio, akā e hoʻemi nui ʻia kā lākou hana i ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe, a i ʻole nā ​​​​​​wahi waikawa-base ikaika, ʻaʻole hiki ke hoʻokō i ke koi e hoʻonui nei o ka hana ʻoihana.
ʻO ka puka ʻana mai o nā mea silicon carbide ua lawe mai i kahi hopena kūpono i ka pilikia o nā pamu slurry lining. ʻO Silicon carbide kahi ʻano mea keramika hou me nā waiwai maikaʻi loa, e like me kona paʻakikī kiʻekiʻe loa, ʻo ka lua wale nō i ka daimana. Hiki i kēia i ka lining silicon carbide ke pale pono i ka ʻino ʻana o nā ʻāpana paʻa i loko o ka slurry, e hoʻomaikaʻi nui ana i ke kūpaʻa ʻana o ka pamu slurry; Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka corrosion a hiki ke kū i nā ʻano waikawa inorganic āpau, nā waikawa organik, a me nā alkalis. Loaʻa iā ia kahi ākea o nā manaʻolana noi i nā ʻoihana e like me ka ʻenekinia kemika e pono ai ke kūpaʻa corrosion kiʻekiʻe; Loaʻa i ka Silicon carbide ke kūpaʻa kemika maikaʻi a hiki ke mālama i ka hana paʻa ma lalo o nā kūlana koʻikoʻi e like me ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe. ʻAʻole maʻalahi ka hana ʻana i nā hopena kemika, e hiki ai iā ia ke hana maʻamau i nā ʻano ʻoihana like ʻole.

Mai ka manaʻo o nā hopena hoʻohana pono, ʻike nui ʻia nā pono o nā pamu slurry silicon carbide lining. ʻO ka mea mua, ua hoʻolōʻihi nui ʻia kona ola lawelawe. Ke hoʻohālikelike ʻia me nā mea lining kuʻuna, hiki i ke kūpaʻa ʻaʻahu o ka lining silicon carbide ke piʻi i nā manawa he nui o nā alloys pale chromium kiʻekiʻe, hiki ke hōʻemi nui i ke alapine o ka mālama ʻana a me ka hoʻololi ʻana i nā lako, a hoʻohaʻahaʻa i nā kumukūʻai hana o nā ʻoihana. ʻO ka lua, ma muli o ka ʻili laumania o ka lining silicon carbide, hiki iā ia ke hōʻemi pono i ke kūpaʻa kahe o ka slurry i ka wā o ka lawe ʻana, hoʻomaikaʻi i ka hana pono o ka pamu, a pēlā e mālama ai i ka hoʻohana ʻana i ka ikehu. Eia kekahi, kiʻekiʻe ke kūpaʻa o ka lining silicon carbide, hiki ke hoʻololi i nā ʻano hana paʻakikī like ʻole a hāʻawi i nā hōʻoia ikaika no ka hoʻomau a me ke kūpaʻa o ka hana ʻoihana.
ʻO ka uhi pamu slurry silicon carbide, ma ke ʻano he mea hana kiʻekiʻe, ua hōʻike i nā pono nui a me ka hiki ke hana ma ke kahua o ka halihali ʻoihana. Me ka holomua mau o ka ʻenehana a me ka emi mālie o nā kumukūʻai, ua manaʻoʻiʻo ʻia e hoʻohana nui ʻia ia ma nā ʻoihana hou aʻe, e hāʻawi ana i ke kākoʻo ikaika no ka hoʻomohala ʻana i ka hana ʻoihana.
