Ubuhlalu be-Drift wuhlobo lwebhola elingenalutho lempukane elingantanta phezu kwamanzi.Inombala ompunga omhlophe, inezindonga ezincane nezingenalutho, nesisindo esilula kakhulu.Iyunithi isisindo 720kg/m3 (sinda), 418.8kg/m3 (ukukhanya), futhi usayizi wezinhlayiyana cishe 0.1mm.Indawo ivaliwe futhi ibushelelezi, ine-conductivity ephansi ye-thermal kanye nokumelana nomlilo okungu-≥ 1610 ℃.Kuyinto enhle kakhulu egcina izinga lokushisa le-refractory, esetshenziswa kabanzi ekukhiqizeni ama-castable angasindi kanye nokumba uwoyela.Ukwakheka kwaKhemikhali kobuhlalu obuntantayo ikakhulukazi i-silicon dioxide ne-aluminium oxide.Inezici zezinhlayiya ezinhle, okungenalutho, isisindo esincane, amandla aphezulu, ukumelana nokugqoka, ukumelana nokushisa okuphezulu, ukufakwa kwe-thermal, ukufakwa kwe-insulation kanye ne-flame retadancy.Ingenye yezinto zokusetshenziswa ezisetshenziswa kakhulu embonini yokumelana nomlilo.
Indlela yokwakheka kobuhlalu obuntantayo: Izikhungo zamandla kagesi ezisebenza ngamalahle zivame ukugaya amalahle abe yimpushana yamalahle bese ziwafafaza esithandweni sikabhayela ophehla ugesi, okuwuvumela ukuba umiswe futhi ushiswe.Iningi lezingxenye ezivuthayo zamalahle (i-carbon ne-organic matter) ziyashiswa, kuyilapho izingxenye ezingashi zobumba (i-silicon, i-aluminium, insimbi, i-magnesium, njll.) ziqala ukuncibilika ekushiseni okuphezulu kwe-1300 degrees Celsius esithandweni, ukwakha umzimba we-symbiotic onezimbotshana zengilazi ye-quartz ne-mullite.
Umthombo womlotha wezimpukane ubuhlalu obuntantayo
Ubuhlalu obuntantayo be-fly ash bubhekisela kuma-microsphere engilazi angenalutho anobuningi obungaphansi kwamanzi akumlotha wezimpukane, okuwuhlobo lomlotha womlotha wempukane njengezinhlayiyana futhi aqanjwe ngokukwazi kwawo ukuntanta emanzini.Isizukulwane sawo yilapho kushiswa impushana yamalahle kubhayela wesikhungo samandla ashisayo, into yobumba inyibilika ibe amaconsi amancane, ajikeleza ngesivinini esikhulu ngaphansi kwesenzo somoya oshisayo onesiyaluyalu esithandweni somlilo, sakhe imbulunga ye-silicon aluminium eyindilinga.Amagesi afana ne-nitrogen, i-hydrogen, ne-carbon dioxide akhiqizwa ukusha nokuqhekeka kokuqhekeka anda ngokushesha ngaphakathi kwendawo encibilikisiwe ye-silicon aluminium aluminium encibilikisiwe, yakhe amabhamuza engilazi angenalutho ngaphansi kokudonsa kwamanzi.Abese efaka umtshingo ukuze aphole ngokushesha futhi aqine, enze ama-microspheres angenalutho engilazi evacuum ephezulu, okungukuthi ubuhlalu obuntantayo be-fly ash.
Ubuhlalu obuntantayo be-fly ash buvela kumlotha wezimpukane futhi bunezici eziningi zomlotha wezimpukane.Kodwa-ke, ngenxa yezimo zayo eziyingqayizivele zokwakheka, zinokusebenza okuphezulu uma kuqhathaniswa nomlotha we-fly.Ziyimpahla yempushana engasindi engeyona eyensimbi esebenza ngezinto eziningi futhi zaziwa njengezisetshenziswa zenkathi yesikhala.
