Mu mafakitale otentha kwambiri monga kupanga simenti, kupanga zitsulo, ndi kupanga magalasi, zipangizo zotsutsa ndizofunikira kwambiri pa kukhazikika kwa ntchito komanso kuwongolera ndalama.Njerwa za spinel za Magnesia alumina, chisankho chabwino kwambiri kwa ogwiritsa ntchito mafakitale padziko lonse lapansi, chimasiyana kwambiri ndi kutentha, kukana dzimbiri, komanso kukonda zachilengedwe.Bukuli likufotokoza zinthu zofunika kwambiri pa njerwa za spinel za magnesia alumina zomwe zingakuthandizeni pa ntchito zanu zamakampani.
1. Tanthauzo la Magnesia Alumina Spinel Bricks
Njerwa za spinel za Magnesia alumina ndi zinthu zopangidwa ndi alkaline refractory zomwe zimapangidwa makamaka ndi magnesium oxide yoyera kwambiri (MgO, 80%-92%) ndi aluminium oxide (Al₂O₃, 3%-14%). Magawo awo akuluakulu a crystalline—periclase ndi magnesia-alumina spinel (MgO·Al₂O₃)—amapanga kapangidwe kokhazikika kudzera mu kutentha kwambiri. Monga njira ina yopanda chromium m'malo mwa refractories yachikhalidwe, njerwa za spinel za magnesia alumina zimapewa kutulutsa poizoni wa hexavalent chromium, zomwe zimagwirizana kwathunthu ndi miyezo yapadziko lonse lapansi yazachilengedwe.
2. Katundu Wofunika Kwambiri wa Magnesia Alumina Spinel Bricks
Makhalidwe abwino kwambiri a njerwa za spinel za magnesia alumina ndi awa:
- ① Kukhazikika kwa kutentha kwabwino kwambiri, kupirira mafunde 12-20 ozizira madzi pa 1100°C;
- ② Kukana kutentha kwambiri, komwe kumasungunuka pa 2135°C komanso kukana kuzizira pamene zinthu zili mkati >1700°C;
- ③ Kukana dzimbiri ndi slag motsutsana ndi slag za alkaline, mpweya wa acidic, ndi zitsulo za alkali;
- ④ Mphamvu yodalirika ya kapangidwe kake, yokhala ndi kuchuluka kwakukulu ≥2.90 g/cm³ ndi mphamvu yozizira yophwanyira ≥45 MPa.
3. Kugwiritsa Ntchito Kwambiri kwa Magnesia Alumina Spinel Bricks
Njerwa za Magnesia alumina spinel ndi zabwino kwambiri m'malo otentha kwambiri: malo osinthira uvuni wozungulira wa simenti, zingwe zachitsulo, zokonzanso ng'anjo yagalasi, ndi zingwe za ng'anjo ya petrochemical. Kusinthasintha kwawo kumapangitsa njerwa za magnesia alumina spinel kukhala zoyenera kugwiritsidwa ntchito mumlengalenga wa alkaline komanso wosakanikirana.
4. Malangizo Osankhira Njerwa za Magnesia Alumina Spinel
Mukasankha njerwa za spinel za magnesia alumina, yang'anani mfundo zitatu zofunika: gwirizanitsani chiŵerengero cha MgO/Al₂O₃ ndi mlengalenga wa ntchito yanu, tsimikizirani magawo aukadaulo apakati (kuchuluka kwa bulk, kukana kutentha), ndikuwona ziphaso zaubwino wa ogulitsa.Konzani bwino njerwa za magnesia alumina spinel zomwe zayesedwa kuti zigwirizane ndi mafakitale anu kuti muwonetsetse kuti zikugwira ntchito bwino komanso kuti ntchito yanu ikhale yayitali.
Njerwa za spinel za Magnesia alumina zimaphatikiza magwiridwe antchito ndi kukhazikika, zomwe zimapangitsa kuti zikhale ndalama zanzeru zamafakitale amakono otentha kwambiri. Sankhani njerwa zoyenera za spinel za magnesia alumina kuti muwonjezere kudalirika kwa zida ndikuchepetsa ndalama zokonzera.
