Ukwakhiwa kweekhemikhali eziphambili zeentsimbi ezidadayo yi-oxide ye-silicon kunye ne-aluminium, apho umxholo we-silicon dioxide malunga ne-50-65%, kunye nomxholo we-aluminium oxide malunga ne-25-35%.Ngenxa yokuba indawo yokunyibilika ye-silica iphezulu njenge-1725 ℃ kwaye eye-alumina yi-2050 ℃, zonke zizinto eziphezulu zokuchasa.Ke ngoko, amaso adadayo anobuqhophololo obuphezulu kakhulu, ukuya kuthi ga kwi-1600-1700 ℃, nto leyo ezenza zibe zirefractories ezisebenza kakuhle kakhulu.Ubunzima bokukhanya, ukufakwa kwe-thermal.Udonga lwamaso oludadayo lubhityile kwaye alunamngxunya, umngxuma ongaphakathi yi-semi vacuum, kuphela isixa esincinci segesi (N2, H2 kunye ne-CO2, njl.), kwaye ukuhanjiswa kobushushu kucotha kakhulu kwaye kuncinci kakhulu.Ngoko ke, amaso ezidadayo akukho ukukhanya kuphela ubunzima (volume ubunzima 250-450 kg / m3), kodwa kwakhona egqwesileyo insulation thermal (conductivity thermal 0.08-0.1 kwiqondo lobushushu gumbi), nto leyo ibeka isiseko ukuba badlale indima ebalulekileyo. kwintsimi yokukhanya kwe-thermal insulation materials.

Ubunzima obuphezulu kunye namandla.Ngenxa yokuba i-bead edadayo ngumzimba weglasi oqinileyo owenziwe yi-silica alumina mineral phase (quartz kunye ne-mullite), ubunzima bayo bunokufikelela ku-Mohs 6-7, amandla oxinzelelo lwe-static anokufikelela kwi-70-140mpa, kwaye ubuninzi bayo bokwenene yi-2.10-2.20g / cm3 , elilingana nelitye.Ngoko ke, amaso adadayo anamandla aphezulu.Ngokubanzi, i-porous elula okanye izixhobo ezingenanto ezifana ne-perlite, ilitye elibilayo, i-diatomite, i-sepiolite kunye ne-vermiculite eyandisiweyo inobunzima kunye namandla.Iimveliso zokugquma kwe-thermal okanye iimveliso ezikhanyelayo ezikhanyayo ezenziwe kuzo zinobugwenxa bamandla amabi.Ukusilela kwabo ngamandla amaso adadayo, ngoko ke amaso adadayo aneengenelo ezikhuphisanayo kunye nokusetyenziswa ngokubanzi.Ubungakanani besuntswana bulungile kwaye indawo ethile yendawo inkulu.Ubungakanani bendalo bamaso adadayo yi-1-250 μ M. Indawo ethile yendawo yi-300-360cm2 / g, efana nesamente.Ngoko ke, amaso adadayo anokusetyenziswa ngokuthe ngqo ngaphandle kokusila.

Ukulunga kunokwanelisa iimfuno zeemveliso ezahlukeneyo, ezinye izinto ezilula zokufakelwa kwe-thermal ngokubanzi ubukhulu becala (ezifana ne-perlite, njl.)Kule nkalo, amaso adadayo aneengenelo.Ukufakelwa kombane okugqwesileyo.Amaso adadayo zizinto ezigqwesileyo zokugquma kwaye aziqhubeki.Ngokubanzi, ukuxhathisa kwe-insulator kuncipha ngokunyuka kwamaqondo obushushu, kodwa ukuxhathisa kwentsimbi edadayo kuyanda ngokunyuka kwamaqondo obushushu.Olu ncedo alunazo ezinye izinto zokugquma.Ngoko ke, inokwenza iimveliso zokugquma phantsi kweemeko eziphezulu zokushisa.
