Drift bead ndi mtundu wa mpira womwe umayandama pamadzi.Ndi yotuwa yotuwa, yokhala ndi makoma opyapyala komanso opanda dzenje, komanso yolemera kwambiri.Kulemera kwa unit ndi 720kg/m3 (kulemera), 418.8kg/m3 (kuwala), ndi kukula kwa tinthu pafupifupi 0.1mm.Pamwambapo ndi otsekedwa komanso osalala, otsika matenthedwe matenthedwe komanso kukana moto kwa ≥ 1610 ℃.Ndi chinthu chabwino kwambiri chosungira kutentha, chomwe chimagwiritsidwa ntchito kwambiri popanga ma castables opepuka komanso kubowola mafuta.Kapangidwe kakemidwe ka mkanda woyandama ndi silicon dioxide ndi aluminium oxide.Ili ndi mawonekedwe a tinthu tating'onoting'ono, tobowo, kulemera kopepuka, mphamvu yayikulu, kukana kuvala, kukana kutentha kwambiri, kutchinjiriza kwamafuta, kutchinjiriza ndi retardancy yamoto.Ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pamakampani olimbana ndi moto.

Kapangidwe ka mikanda yoyandama: Makina opangira magetsi oyaka ndi malasha nthawi zambiri amagaya malasha kukhala ufa wamalasha ndikuwapopera mu ng'anjo yopangira magetsi, kuwalola kuyimitsidwa ndi kuwotchedwa.Zambiri zomwe zimatha kuyaka za malasha (carbon ndi organic matter) zimatenthedwa, pomwe zinthu zosayaka zadongo (silicon, aluminiyamu, chitsulo, magnesium, etc.) zimayamba kusungunuka pa kutentha kwa madigiri 1300 Celsius mu ng'anjo, kupanga porous symbiotic thupi la galasi la quartz ndi mullite.

Gwero la mikanda yoyandama ya ntchentche
Mikanda yoyandama ya ntchentche imatanthawuza magalasi ang'onoang'ono omwe ali ndi kachulukidwe kakang'ono kuposa madzi a phulusa la ntchentche, omwe ndi mtundu wa mkanda wa ntchentche ngati tinthu tating'onoting'ono ndipo amatchulidwa chifukwa cha luso lawo loyandama pamadzi.Mbadwo wake ndi pamene ufa wa malasha umatenthedwa mu chowotcha chamagetsi opangira magetsi, zinthu zadongo zimasungunuka kukhala madontho ang'onoang'ono, omwe amazungulira mofulumira kwambiri chifukwa cha chipwirikiti cha mpweya wotentha mu ng'anjo, ndikupanga kuzungulira kwa silicon aluminium sphere.Mipweya monga nayitrogeni, haidrojeni, ndi kaboni dayokisaidi wopangidwa ndi kuyaka ndi kuphwanyidwa kwake kumakula mwachangu mkati mwa chitsulo chosungunuka cha silicon aluminium sphere, kupanga thovu lagalasi lopanda kanthu pansi pa zovuta zapamtunda.Kenako amalowa mu chitoliro cha kuziziritsa mofulumira ndi kuumitsa, kupanga magalasi apamwamba a vacuum opanda ma microspheres, omwe ndi mikanda yoyandama ya phulusa.

Mikanda yoyandama ya ntchentche imachokera ku phulusa la ntchentche ndipo imakhala ndi zinthu zambiri za phulusa la ntchentche.Komabe, chifukwa cha mapangidwe ake apadera, ali ndi ntchito yabwino kwambiri poyerekeza ndi phulusa la ntchentche.Ndizinthu zopepuka zopanda zitsulo zosapanga dzimbiri zatsopano za ufa ndipo zimadziwika kuti zida zazaka zakuthambo.
