Zabwino kwambiri komanso kugwiritsa ntchito cenospheres.

Zabwino kwambiri komanso kugwiritsa ntchitocenospheres : high refractoriness. Waukulu mankhwala zigawo zikuluzikulu zacenospheres Ma oxides a silicon ndi aluminiyamu, omwe silicon dioxide ali pafupifupi 50-65%, ndi aluminium oxide pafupifupi 25-35%. Chifukwa chakuti silika imasungunuka kufika madigiri 1725 Celsius, malo osungunuka a aluminium oxide ndi 2050 digiri Celsius, onse awiri ndi apamwamba.zipangizo zokana . Chifukwa chake, ma cenospheres ali ndi refractoriness kwambiri, nthawi zambiri amafika madigiri 1600-1700 Celsius, kuwapanga kukhala zinthu zapamwamba kwambiri zokana. Zopepuka, zotsekemera zotentha. Khoma la cenospheres ndi lopyapyala komanso lopanda kanthu, ndipo patsekekeyo ndi yopanda kanthu, yokhala ndi mpweya wochepa kwambiri (N2, H2 ndi CO2, etc.), ndipo kuchititsa kutentha kumakhala pang'onopang'ono komanso kochepa kwambiri. Chifukwa chake, ma cenospheres samangokhala opepuka kulemera (kachulukidwe kachulukidwe 250-450 kg/m3), komanso abwino kwambiri pakutchinjiriza kwamafuta (kutentha kwapakati pa kutentha kwa 0.08-0.1), komwe kumayala maziko kuti awonetse luso lawo m'munda. wa zida zopepuka zotenthetsera matenthedwe. Kuuma kwakukulu ndi mphamvu. Chifukwa ma cenospheres ndi matupi agalasi olimba omwe amapangidwa ndi silicon aluminium oxide mineral phases (quartz ndi mullite), kuuma kumatha kufika pamlingo wa Mohs 6-7, mphamvu ya static pressure ndiyokwera 70-140MPa, ndipo kachulukidwe kowona ndi 2.10-2.20 g/cm3. kufanana ndi rock. Chifukwa chake, ma cenospheres ali ndi mphamvu zambiri. Nthawi zambiri, zinthu zopepuka za porous kapena dzenje monga perlite, zeolite, diatomite, pumice, vermiculite yowonjezera, ndi zina zotere zimakhala ndi kuuma komanso mphamvu zochepa, ndipo zinthu zotchinjiriza zotenthetsera kapena zopepuka zopepuka zopangidwa ndi iwo zimakhala ndi zovuta zake. Zofooka zawo ndizo zabwino za cenospheres, kotero kuti ma cenospheres ali ndi ubwino wampikisano komanso ntchito zambiri. Fine tinthu kukula ndi lalikulu enieni pamwamba m'dera. Kukula kwa tinthu ta mikanda yopangidwa mwachilengedwe ndi 1-250 microns. Malo enieni ndi 300-360cm2 / g, omwe ndi ofanana ndi simenti. Choncho, cenospheres angagwiritsidwe ntchito mwachindunji popanda akupera. The fineness akhoza kukwaniritsa zosowa zosiyanasiyana mankhwala. Zida zina zotchinjiriza zopepuka nthawi zambiri zimakhala ndi tinthu tating'onoting'ono (monga perlite, ndi zina). Ngati ali pansi, mphamvuyo idzawonjezeka kwambiri, ndipo kutentha kwa kutentha kudzachepetsedwa kwambiri. Pachifukwa ichi, ma cenospheres ali ndi mwayi. Kusungunula kwabwino kwamagetsi. Cenospheres, pambuyo posankhidwa mikanda ya maginito, ndi zipangizo zabwino zotetezera komanso zosagwiritsa ntchito. Kawirikawiri, kukana kwa insulators kumachepa ndi kuwonjezeka kwa kutentha, koma kukana kwa cenospheres kumawonjezeka ndi kuwonjezeka kwa kutentha. Ubwino uwu supezeka ndi zida zina zotetezera. Chifukwa chake, imatha kupanga zinthu zodzitetezera ku kutentha kwambiri.
