Ma nā kahua ʻoihana e like me ka mining, metallurgy, a me ka mana, ʻo nā pamu slurry nā lako koʻikoʻi no ka lawe ʻana i nā mea ʻino a me nā mea ʻino loa. ʻOiai he ikaika kiʻekiʻe nā kino pamu metala kuʻuna, kū pinepine lākou i nā pilikia o ka ʻino wikiwiki a me ke ola lawelawe pōkole i ka wā e kū nei i nā kūlana hana paʻakikī. I nā makahiki i hala iho nei, ʻo ka hoʻopili ʻana o kahi ʻano mea hou -nā keramika silicon carbide- ua lawe i ka lōʻihi a me ka pono o nā pamu slurry i kahi pae hou.
1, nā keramika carbide Silicon: mai nā "niho ʻoihana" a hiki i nā mea kino o ka pamu
Ua kapa ʻia ʻo Silicon carbide (SiC) ʻo ia ka "niho ʻoihana", me ka paʻakikī ma hope o ke daimana akā ʻoi aku ka māmā ma mua o nā metala. Ua hoʻohana mua ʻia kēia mea no ka wili ʻana i nā huila a me nā mea ʻoki. Ma hope mai, ua ʻike nā kānaka ʻepekema e hiki i kona kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa kemika ke hoʻoponopono i nā wahi ʻeha o nā pamu slurry:
ʻO ke kūpaʻa i ke kapa komo a me ke kūpaʻa i ka palaho: ʻO kona paʻakikī ka lua wale nō i ka daimana, a hiki ke kū maʻalahi i ka ʻino ʻana o nā mea pāpaho e loaʻa ana ke one, ka ʻiliʻili, a me nā ʻāpana;
ʻO ka anti-corrosion kūlohelohe: He kūpaʻa ikaika ia i ka waikawa ikaika a me nā hopena ʻē aʻe, e pale ana i nā pilikia corrosion maʻamau o nā pamu metala;
Hoʻolālā māmā: Hoʻokahi hapakolu wale nō o ke kila ka nui o ka density, e hōʻemi ana i ka ukana o nā lako a me ka hoʻohana ʻana i ka ikehu.
2, ʻO nā pono koʻikoʻi ʻekolu o nā pamu seramika silicon carbide
1. Hoʻolōʻihi i ke ola ma nā manawa he nui
Pono paha nā pamu metala kuʻuna e hoʻololi i nā impellers a me nā pahu pamu i loko o nā mahina i ka wā e lawe ana i nā slurries abrasive, ʻoiai hiki i nā mea silicon carbide ke hana paʻa no kekahi mau makahiki, e hoʻemi nui ana i ke alapine o ka downtime a me ka mālama ʻana.
2. E hōʻemi i nā kumukūʻai mālama
Ma muli o ka emi ʻana o ke komo ʻana a me ka waimaka, ua hoʻolōʻihi ʻia ke kaʻina hana hoʻololi o nā mea pono, a ʻaʻole pono nā ʻāpana seramika i ka mālama pinepine ʻana i ka corrosion, e hopena ana i ka emi nui ʻana o nā kumukūʻai mālama holoʻokoʻa.
3. ʻOi aku ka paʻa o ka pono
He kiʻekiʻe loa ka laumania o ka ʻili o nā keramika, a ʻaʻole maʻalahi ka hana ʻana i nā lua a i ʻole nā deformations i ka hoʻohana lōʻihi. Mālama mau ia i kahi ala lawe waena laumania e pale aku i ka hōʻino ʻana o ka pono.
3, He aha nā hiʻohiʻona e pono ai nā pamu seramika silicon carbide?
Nā kūlana ʻāwili koʻikoʻi: e like me ka lawe ʻana i nā ʻōpala mining, ka mālama ʻana i ka slurry lanahu i nā hale holoi lanahu
Kaiapuni ʻino ikaika: ka lawe ʻana o ka waikawa ikaika a me nā mea pāpaho ʻē aʻe i ka ʻoihana kemika, ka hoʻolaha ʻana o ka slurry desulfurization
Kahua koi maʻemaʻe kiʻekiʻe: Hiki i nā ʻano inert o nā mea seramika ke pale aku i ka haumia ion metala o ka medium
4. Nā akahele no ke koho ʻana
ʻOiai he hana maikaʻi loa nā pamu seramika silicon carbide, pono lākou e hoʻohālikelike ʻia e like me nā kūlana hana kikoʻī:
Manaʻo ʻia e koho i ka silicon carbide sintered reaction (me ke kūpaʻa hopena ikaika) ma ke ʻano he medium particle ultrafine
Pono e uku ʻia ka nānā ʻana i nā mea sila a me ka hoʻolālā kūkulu ʻana i nā wahi wela kiʻekiʻe
E pale i nā kuʻi koʻikoʻi i ka wā o ke kau ʻana (ʻoi aku ka palupalu o ka mea seramika ma mua o ka metala)
hopena
Ma ke ʻano he "kahu pale ʻaʻahu" i ke kahua ʻoihana, ke paipai nei nā pamu slurry ceramic silicon carbide i ka hoʻomaikaʻi ʻana o nā ʻoihana kuʻuna i ka pono kiʻekiʻe a me ka palekana o ke kaiapuni me ke ola lawelawe lōʻihi a me ka hoʻohana ʻana i ka ikehu haʻahaʻa. No nā ʻoihana, ʻo ke koho ʻana i kahi ʻano pamu pale ʻaʻahu kūpono ʻaʻole wale ia he mālama i nā kumukūʻai lako, akā he hōʻoia koʻikoʻi hoʻi no ka hoʻomau ʻana o ka hana a me ka palekana.
ʻO Shandong Zhongpengua komo nui ʻo ia i ke kahua o nā mea pale ʻaʻahu no nā makahiki he ʻumi a ʻoi, a ua mākaukau e hāʻawi i nā hopena lōʻihi i kāu mau pilikia halihali ʻoihana me ka ʻenehana mea hou.
