Iipropati ezigqwesileyo kunye nokusetyenziswa kwe-cenospheres.

Iipropati ezigqwesileyo kunye nokusetyenziswa kweiicenospheres : ukuchasa okuphezulu. Amacandelo aphambili ekhemikhaliiicenospheres Iioksidi ze-silicon kunye ne-aluminium, apho i-silicon dioxide i malunga ne-50-65%, kunye ne-aluminium oxide malunga ne-25-35%. Ngenxa yokuba indawo yokunyibilika yesilica 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 (i-N2, i-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 nokuqina 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 beqhekeza 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 ngokubanzi zineesayizi ezinkulu (ezifana ne-perlite, njl.). Ukuba ziphantsi komhlaba, umthamo uya kwandiswa kakhulu, kwaye i-thermal insulation iya kuncitshiswa kakhulu. Kule nkalo, i-cenospheres inenzuzo. Ukufakelwa kombane okugqwesileyo. I-Cenospheres, emva kokuba ubuhlalu obuzibuthe bukhethiweyo, zizinto ezigqwesileyo zokugquma kunye ne-non-conductive. 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 zokukhusela phantsi kweemeko eziphezulu zokushisa.
