Iimpawu ezigqwesileyo kunye nokusetyenziswa kwecenospheres.

Iipropati ezigqwesileyo kunye nokusetyenziswa kweiicenospheres: ukuchasa okuphezulu.Amacandelo aphambili ekhemikhaliiicenospheresIioksidi ze-silicon kunye ne-aluminium, apho i-silicon dioxide imalunga ne-50-65%, kunye ne-aluminium oxide malunga ne-25-35%.Ngenxa yokuba indawo yokunyibilika kwesilica iphezulu ukuya kutsho kwi-1725 degrees celcius, indawo yokunyibilika kwe-aluminiyam oxide yi-2050 degrees celcius, zombini ziphezulu.izinto eziphikisayo.Ke ngoko, iicenospheres zinerefractoriness ephezulu kakhulu, ifikelela kwi-1600-1700 degrees Celsius, izenza zibe yeyona nto ibalaseleyo yokusebenza kwesixhobo sokuchasa.I-lightweight, i-thermal insulation.Udonga lwe-cenospheres luncinci kwaye luvulekile, kwaye i-cavity i-semi-vacuum, inexabiso elincinci kakhulu legesi (N2, H2 kunye ne-CO2, njl.), kwaye ukuhanjiswa kobushushu kucotha kakhulu kwaye kuncinci kakhulu.Ngoko ke, i-cenospheres ayilulanga kuphela ubunzima (i-bulk density 250-450 kg / m3), kodwa iphinda ihle kakhulu kwi-thermal insulation (i-thermal conductivity kwiqondo lokushisa 0.08-0.1), ebeka isiseko sokuba babonise iitalente zabo kwintsimi. yezinto ezilula zokugquma i-thermal.Ubunzima obuphezulu kunye namandla.Ngenxa yokuba i-cenospheres yimizimba yeglasi enzima eyenziwe yi-silicon aluminium oxide izigaba zeminerali (i-quartz kunye ne-mullite), ubunzima bunokufikelela kwinqanaba le-Mohs 6-7, amandla oxinzelelo lwe-static aphezulu njenge-70-140MPa, kwaye ubuninzi bokwenene yi-2.10-2.20 g/cm3.ithelekiseka nelitye.Ngoko ke, ii-cenospheres zinamandla aphezulu.Ngokubanzi, iimathiriyeli ezithambileyo ezikhaphukhaphu okanye ezingenanto ezifana neperlite, i-zeolite, i-diatomite, ipumice, i-vermiculite eyandisiweyo, njl.njl. zinobulukhuni kunye nokomelela okulambathayo, kunye neemveliso zokugquma kwe-thermal okanye iimveliso ezikhanyelayo ezikhanyelayo ezenziwe ngazo zinamandla angalunganga.Iintsilelo zabo ziluncedo ngokuchanekileyo kwi-cenospheres, ngoko ke ii-cenospheres zineenzuzo ezikhuphisanayo kunye nokusetyenziswa okubanzi.Ubungakanani bamasuntswana alungileyo kunye nendawo enkulu yendawo ethile.Ubungakanani besuntswana lobuhlalu bendalo buyi-1-250 microns.Indawo ethile yendawo yi-300-360cm2 / g, efana nesamente.Ngoko ke, i-cenospheres ingasetyenziselwa ngokuthe ngqo ngaphandle kokugaya.Ukulunga kunokwanelisa iimfuno zeemveliso ezahlukeneyo.Ezinye izinto ezilula zokugquma i-thermal zineesayizi ezinkulu (ezifana ne-perlite, njl.).Ukuba ziphantsi, umthamo uya kwandiswa kakhulu, kwaye i-thermal insulation iya kuncitshiswa kakhulu.Kule nkalo, i-cenospheres inenzuzo.Ukufakelwa kombane okugqwesileyo.I-Cenospheres, emva kokuba kukhethwe ubuhlalu bamagnetic, zizinto ezigqwesileyo zokukhusela kunye nezingaqhubekiyo.Ngokuqhelekileyo, ukuchasana kwe-insulators kunciphisa ngokunyuka kweqondo lokushisa, kodwa ukuchasana kwe-cenospheres kwanda ngokunyuka kweqondo lokushisa.Olu ncedo alufumaneki kunye nezinye izinto zokukhusela.Ngoko ke, inokwenza iimveliso ze-insulating phantsi kweemeko eziphezulu zokushisa.
