Pilikika Palekana Silica | Pilikika Ahi Silica Palekana ʻAkika SiO₂ Kiʻekiʻe no ka Umu Wela Kiʻekiʻe
E lilo i kahua no ka hoʻokō ʻana i nā moeʻuhane o kā mākou poʻe limahana! E kūkulu i kahi poʻe hana ʻoi aku ka hauʻoli, ʻoi aku ka lokahi a me ka ʻoihana akamai! E hoʻokō i ka loaʻa kālā like o kā mākou poʻe kūʻai, nā mea hoʻolako, ke kaiāulu a me mākou iho noPilikika Paʻakikī Silica, I kēia manawa, loaʻa iā mākou kahi hui maikaʻi loa e hoʻolako ana i ka lawelawe loea, ka pane wikiwiki, ka lawe manawa kūpono, ka maikaʻi loa a me ke kumukūʻai maikaʻi loa i kā mākou mea kūʻai aku. ʻO ka ʻoluʻolu a me ka hōʻaiʻē maikaʻi i kēlā me kēia mea kūʻai aku kā mākou mea nui. Ke kakali nei mākou me ka ʻoiaʻiʻo e hana pū me nā mea kūʻai aku ma ka honua holoʻokoʻa. Manaʻo mākou hiki iā mākou ke ʻoluʻolu me ʻoe. Hoʻokipa maikaʻi pū mākou i nā mea kūʻai aku e kipa i kā mākou hui a kūʻai i kā mākou huahana.
Nā pōhaku lepo paʻa silicahe mau mea refractory kiʻekiʻe i hoʻohana nui ʻia ma nā ʻano ʻoihana like ʻole o ke ana wela kiʻekiʻe.
1. ʻIke Kumu
Nā ʻĀpana Nui:He mea paʻakikī waikawa ia me ka silicon dioxide (SiO₂) ma ke ʻano he mea nui, ʻoi aku ma mua o 93% ka nui, a ʻo ka nui o nā piliki silica kiʻekiʻe e hiki ke piʻi i kahi 96%.
Ka Hoʻohui Kemika Maʻamau:Ma waho aʻe o ka SiO₂, loaʻa pū kekahi wahi liʻiliʻi o Al₂O₃ (ma kahi o 0.8% - 1%), MgO (ma kahi o 0.001%), CaO (ma kahi o 0.002%), a me Fe₂O₃ (ma kahi o 0.7% - 1.5%).
Nā Waiwai Kino:ʻO ka refractoriness maʻamau ma waena o 1770°C a me 2000°C. ʻO ka refractoriness ma lalo o kahi ukana o 0.2MPa he 1630°C - 1680°C. ʻO ka ikaika kuʻi anu he 30 - 35MPa, ʻo ka nui o ka nui he 1.8g/cm³, a ʻo ka porosity maopopo he 21% - 22%.
2. Kaʻina Hana
ʻO ke kaʻina hana e komo pū ana me ke koho ʻana i nā mea maka, ke ʻano, ke puhi ʻana, a me ka hoʻolulu ʻana. ʻO ka mea maka nui he quartz, a hoʻohui ʻia nā mea hoʻopaʻa e like me ka lime a me nā mea hoʻopaʻa organik. Ma hope o ke kūkulu ʻia ʻana i loko o nā blanks brick, ua puhi ʻia lākou i kahi mahana kiʻekiʻe o 1350°C - 1430°C. Pono ke kaʻina hana puhi i ka kaohi mahana pololei, a pono hoʻi e hana mālie ʻia ke kaʻina hoʻolulu e pale aku i nā māwae i hoʻokumu ʻia e nā loli wikiwiki o ka nui.
Nā Hiʻohiʻona:
1. Ke kūpaʻa ikaika i ka ʻino ʻana o ka slag acidic:Loaʻa i nā piliki silica ke kūpaʻa ikaika i nā mea ʻino e like me ka ʻōpala waikawa a me ka metala heheʻe, e hōʻoiaʻiʻo ana i ko lākou ola lawelawe lōʻihi.
2. Ka mahana hoʻoluʻolu kiʻekiʻe:ʻO ke kiʻekiʻe o ka mahana hoʻoluʻolu o nā piliki silica he 1640-1670℃, a paʻa ka nui ma lalo o ka hoʻohana lōʻihi ma ke ana wela kiʻekiʻe.
3. Paʻa maikaʻi o ka leo:Ma kahi mahana kiʻekiʻe o 1600℃, hiki i nā piliki silica ke mālama i kahi ʻano paʻa a loaʻa ka helu kolo haʻahaʻa.
4. Paʻa kemika kiʻekiʻe:He kūpaʻa maikaʻi ko nā piliki silica i nā oxides e like me Al2O3, FeO, Fe2O3, akā he kūpaʻa haʻahaʻa i ka alkaline slag (e like me CaO, K2O, Na2O).

1. Hoʻohana nui ʻia nā piliki silica i loko o ka paia mahele o ke keʻena kalapona a me ke keʻena kuni o ka umu coke, ke keʻena hoʻoulu hou a me ke keʻena sediment o ka umu kapuahi hāmama o ka hana kila, ka umu hoʻomehana maʻamau, nā mea refractory o ke aniani hoʻoheheʻe umu a me ka umu seramika, a me nā ʻāpana ʻē aʻe o ka umu.
Nā Nīnau i Nīnau Pinepine ʻia
Pono kōkua? E kipa aku i kā mākou mau kahua kākoʻo no nā pane i kāu mau nīnau!
He mea hana maoli mākou, ua loea kā mākou hale hana i ka hana ʻana i nā mea refractory no nā makahiki he 30 a ʻoi. Hoʻohiki mākou e hāʻawi i ke kumukūʻai maikaʻi loa, ka lawelawe mua a me ka lawelawe ma hope o ke kūʻai aku.
No kēlā me kēia kaʻina hana, loaʻa iā RBT kahi ʻōnaehana QC piha no ka hoʻohuihui kemika a me nā waiwai kino. A e hoʻāʻo mākou i nā waiwai, a e hoʻouna ʻia ka palapala hōʻoia maikaʻi me nā waiwai. Inā he mau koi kūikawā kāu, e hoʻāʻo mākou i ka maikaʻi loa e hoʻokō iā lākou.
Ma muli o ka nui, ʻokoʻa ka manawa hoʻouna. Akā ke hoʻohiki nei mākou e hoʻouna koke me ka maikaʻi i hōʻoia ʻia.
ʻOiaʻiʻo, hāʻawi mākou i nā laʻana manuahi.
ʻAe, ʻoiaʻiʻo, ua ʻoluʻolu ʻia ʻoe e kipa i ka hui ʻo RBT a me kā mākou huahana.
ʻAʻohe palena, hiki iā mākou ke hāʻawi i ka manaʻo maikaʻi loa a me ka hoʻonā e like me kou kūlana.
Ua hana mākou i nā mea refractory no nā makahiki he 30 a ʻoi, loaʻa iā mākou ke kākoʻo loea ikaika a me ka ʻike waiwai, hiki iā mākou ke kōkua i nā mea kūʻai aku e hoʻolālā i nā kilns like ʻole a hāʻawi i ka lawelawe hoʻokahi.
