iindaba

Intsimbi edadayo luhlobo lwebhola enomngxuma yempukane ekwazi ukudada phezu kwamanzi.Ingwevu emhlophe, ibhityile kwaye inomngxuma eludongeni, ilula kakhulu ubunzima, inobunzima beyunithi ye-720kg/m3 (inzima) kunye ne-418.8kg/m3 (ukukhanya), ubungakanani besuntswana elimalunga ne-0.1mm, ivaliwe kwaye igudileyo kumphezulu, incinci ngaphakathi. conductivity thermal, kunye nokumelana nomlilo ≥ 1610 ℃.Yeyona ndawo ibalaseleyo yogcino lobushushu, isetyenziswa ngokubanzi kwimveliso yokukhanya okuphoswayo kunye nokugrumba ioli.Ukwakheka kweekhemikhali zeliso elidadayo ikakhulu yisilicon dioxide kunye nealuminiyam oxide.Ineempawu ezininzi, ezinje ngamasuntswana amahle, ihollow, ubunzima obulula, amandla aphezulu, ukumelana nokunxiba, ukumelana nobushushu obuphezulu, ukugqunywa kwe-thermal, ukugquma kunye nokubuyiswa komlilo.Ngenye yezinto ezisetyenziswa kakhulu kwishishini lokumelana nomlilo.

Intshayelelo

Ukusebenza okugqwesileyo kunye nokusetyenziswa kwamaso adadayo

Ukumelana nomlilo ophezulu.Izinto eziphambili zeekhemikhali ze-bead edadayo ziyi-silicon kunye ne-aluminium oxides, apho i-silicon dioxide i malunga ne-48-66% kunye ne-aluminium oxide malunga ne-26-36%.Ngenxa yokuba indawo yokunyibilika yesilicon dioxide yi-1720 ℃ kwaye leyo ye-aluminiyam oxide yi-2060 ℃, zombini ziyi-refractories ephezulu.Ke ngoko, i-bead edadayo inokumelana nomlilo okuphezulu kakhulu, okufikelela ngokubanzi kwi-1620-1800 ℃, iyenza ibe yeyona ndlela ibalaseleyo yokusebenza kwerefractory.Ubunzima bokukhanya, ukufakwa kwe-thermal.Udonga lwentsimbi edadayo lubhityile kwaye lunomqolo, kwaye umngxuma lowo ufana ne-semi vacuum.Kukho kuphela umlinganiselo omncinci werhasi (N2, H2, CO2, njl.), kwaye ukuhanjiswa kobushushu kucotha kakhulu.Ngoko ke, amaso adadayo alula nje ubunzima (250-450 kg/m3).Ubungakanani bendalo besuntswana lamaso adadayo yi-1-250 microns.Amaso e-Drift angasetyenziswa ngokuthe ngqo ngaphandle kokusila.Ukulunga kunokwanelisa iimfuno zeemveliso ezahlukeneyo.Ezinye izinto ezikhaphukhaphu zokugquma kwe-thermal ziqhelekile ubukhulu besuntswana elikhulu (njenge-perlite).Ukuba zigaywe, umthamo uya kwandiswa kakhulu, kwaye i-thermal insulation iya kuncitshiswa kakhulu.Ngokubhekiselele koku, amaso e-Drifting aneenzuzo.Ukufakelwa kombane okugqwesileyo.I-bead edadayo emva kokuba i-bead magnetic ikhethiwe yinto ekhuselayo esebenza kakuhle kwaye ayiqhubeki umbane.Ngokuqhelekileyo, ukuxhathisa kwe-insulators kuncipha ngokunyuka kwamaqondo obushushu, ngelixa amaso adadayo anyuka ngokunyuka kwamaqondo obushushu.Olu ncedo alunazo ezinye izinto zokugquma.Ngoko ke, ingasetyenziselwa ukwenza iimveliso ze-insulating phantsi kweemeko eziphezulu zokushisa.
