Eyona khemikhali iphambili yee-floating beads yi-oxide ye-silicon kunye ne-aluminium, apho umxholo we-silicon dioxide umalunga ne-50-65%, kwaye umxholo we-aluminium oxide umalunga ne-25-35%. Ngenxa yokuba iqondo lokunyibilika kwe-silica liphezulu njenge-1725 ℃ kwaye elo le-alumina liyi-2050 ℃, zonke zizinto ezinokuchasana okuphezulu. Ke ngoko, ii-floating beads zinamandla aphezulu okuchasana okuphezulu, ngokubanzi ukuya kuthi ga kwi-1600-1700 ℃, nto leyo eyenza zibe zi-refractories ezilungileyo kakhulu. Ubunzima obuncinci, ukugquma kobushushu. Udonga lwee-floating beads lubhityile kwaye lungenanto, umngxuma u-semi vacuum, kuphela igesi encinci kakhulu (i-N2, i-H2 kunye ne-CO2, njl.njl.), kwaye ukuhanjiswa kobushushu kuhamba kancinci kwaye kuncinci kakhulu. Ngoko ke, iintsimbi ezidadayo azilulanga nje kuphela ngobunzima (ubunzima bomthamo obuyi-250-450 kg / m3), kodwa zikwabalasele kakhulu ekugqumeni ubushushu (ukuqhuba ubushushu obuyi-0.08-0.1 kubushushu begumbi), nto leyo ebeka isiseko sokuba zidlale indima ebalulekileyo kwicandelo lezixhobo zokukhusela ubushushu obukhanyayo.

Ubunzima obuphezulu kunye namandla. Ngenxa yokuba i-floating bead ngumzimba weglasi oqinileyo owenziwe yi-silica alumina mineral phase (quartz kunye ne-mullite), ubunzima bayo bunokufikelela kwi-Mohs 6-7, amandla oxinzelelo oluzinzileyo anokufikelela kwi-70-140mpa, kwaye ubuninzi bayo bokwenyani yi-2.10-2.20g/cm3, okulingana nobo belitye. Ke ngoko, ii-floating beads zinamandla aphezulu. Ngokubanzi, izinto ezikhanyayo ezinemingxuma okanye ezingenanto ezifana ne-perlite, i-boiling rock, i-diatomite, i-sepiolite kunye ne-expanded vermiculite zinobunzima obuphantsi kunye namandla. Iimveliso zokuthintela ubushushu okanye iimveliso ezikhanyayo ezirhabaxa ezenziwe ngazo zinobunzima bokuqina obuphantsi. Iintsilelo zazo ngamandla nje ee-floating beads, ngoko ii-floating beads zineengenelo ezikhuphisanayo kunye nokusetyenziswa okubanzi. Ubungakanani besuntswana bulungile kwaye indawo ethile yomphezulu inkulu. Ubungakanani bendalo bee-floating beads yi-1-250 μ M. Indawo ethile yomphezulu yi-300-360cm2 / g, efana neyesamente. Ke ngoko, ii-floating beads zingasetyenziswa ngokuthe ngqo ngaphandle kokusila.

Ubunono bunokuhlangabezana neemfuno zeemveliso ezahlukeneyo, ezinye izinto zokukhusela ubushushu ezilula ngokubanzi zinkulu ngobukhulu bamasuntswana (njenge-perlite, njl.njl.), ukuba ukugaya kuya kwandisa kakhulu amandla, ukuze ukhuseleko lobushushu lunciphe kakhulu. Kule nkalo, iibhere ezidadayo zinezibonelelo. Ukhuseleko lombane oluhle kakhulu. Iibhere ezidadayo zizinto zokukhusela ezibalaseleyo kwaye azihambisi moya. Ngokubanzi, ukumelana kwe-insulator kuyehla ngokunyuka kobushushu, kodwa ukumelana kwebhere ezidadayo kuyanda ngokunyuka kobushushu. Eli thuba alinazo ezinye izinto zokukhusela. Ke ngoko, inokwenza iimveliso zokukhusela phantsi kweemeko zobushushu obuphezulu.
