I-Floating bead uhlobo lwebhola elingenalutho elinomlotha ongantanta phezu kwamanzi. Imhlophe qhwa, incane futhi ingenalutho odongeni, ilula kakhulu ngesisindo, inesisindo esingu-720kg/m3 (esinzima) kanye no-418.8kg/m3 (esikhanyayo), ubukhulu bezinhlayiya obungaba ngu-0.1mm, ivaliwe futhi ibushelelezi ebusweni, incane ekuqhutshweni kokushisa, kanye nokumelana nomlilo ≥ 1610 ℃. Iyindlela enhle kakhulu yokugcina izinga lokushisa, esetshenziswa kabanzi ekukhiqizeni izinto ezikhanyayo kanye nokubhoboza uwoyela. Ukwakheka kwamakhemikhali kwe-floating bead ikakhulukazi yi-silicon dioxide kanye ne-aluminium oxide. Inezici eziningi, njengezinhlayiya ezincane, ingenalutho, isisindo esincane, amandla aphezulu, ukumelana nokuguguleka, ukumelana nokushisa okuphezulu, ukuvimbela ukushisa, ukuvimbela ukushisa kanye nokulinda ilangabi. Ingenye yezinto zokusetshenziswa ezisetshenziswa kabanzi embonini yokumelana nomlilo.

Isingeniso

Ukusebenza okuhle kakhulu kanye nokusetshenziswa kwama-bead antantayo

Ukumelana nomlilo okuphezulu. Izakhi zamakhemikhali eziyinhloko ze-floating bead yi-silicon ne-aluminium oxides, lapho i-silicon dioxide ingama-48-66% kanti i-aluminium oxide ingama-26-36%. Ngenxa yokuthi iphuzu lokuncibilika kwe-silicon dioxide lingu-1720 ℃ kanti ele-aluminium oxide lingu-2060 ℃, zombili ziyi-refractories ephezulu. Ngakho-ke, i-floating bead inokumelana nomlilo okuphezulu kakhulu, okuvame ukufinyelela ku-1620-1800 ℃, okwenza kube yi-refractory enhle kakhulu esebenza kahle. Isisindo esincane, ukufudumala kokushisa. Udonga lwe-floating bead luncane futhi lungenalutho, kanti imbobo i-semi vacuum. Kukhona inani elincane kakhulu legesi (N2, H2, CO2, njll.), futhi ukuhanjiswa kokushisa kuhamba kancane kakhulu. Ngakho-ke, i-floating bead ayisisindo esilula kuphela (250-450 kg/m3). Usayizi wezinhlayiya zemvelo ze-floating beads ungama-micron angu-1-250. I-drift beads ingasetshenziswa ngqo ngaphandle kokugaya. Ubuncane bungahlangabezana nezidingo zemikhiqizo ehlukahlukene. Ezinye izinto zokuvikela ukushisa ezilula ngokuvamile zinkulu ngobukhulu bezinhlayiya (njenge-perlite). Uma zigaywa, umthamo uzokwanda kakhulu, futhi ukuvikela ukushisa kuzoncishiswa kakhulu. Kulokhu, ama-Drifting bead anezinzuzo. Ukuvikela kagesi okuhle kakhulu. I-floating bead ngemva kokukhethwa kwe-magnetic bead iyinto yokuvikela ukushisa esebenza kahle kakhulu futhi ayiqhubi ugesi. Ngokuvamile, ukumelana kwama-insulator kunciphisa ngokwanda kwezinga lokushisa, kuyilapho lokho kwama-floating bead kuyanda ngokwanda kwezinga lokushisa. Le nzuzo ayinazo ezinye izinto zokuvikela ukushisa. Ngakho-ke, ingasetshenziswa ukwenza imikhiqizo yokuvikela ukushisa ngaphansi kwezimo zokushisa eziphakeme.
