I-Drift bead uhlobo lwebhola elingenalutho elinomlotha ompukane elingantanta phezu kwamanzi. Linombala ompunga omhlophe, linezindonga ezincane nezingenalutho, futhi linesisindo esincane kakhulu. Isisindo seyunithi singama-720kg/m3 (esinzima), ama-418.8kg/m3 (esilula), kanti usayizi wezinhlayiya ungaba ngu-0.1mm. Ubuso buvaliwe futhi bubushelelezi, bunokushisa okuphansi kanye nokumelana nomlilo okungu-≥ 1610 ℃. Luyinto enhle kakhulu yokugcina ukushisa evimbela ukushisa, esetshenziswa kabanzi ekukhiqizeni izinto ezilula zokusakaza kanye nokubhoboza uwoyela. Ukwakheka kwamakhemikhali kwe-floating bead ikakhulukazi yi-silicon dioxide kanye ne-aluminium oxide. Inezici zezinhlayiya ezincane, ezingenalutho, ezikhanyayo, ezinamandla aphezulu, ukumelana nokuguguleka, ukumelana nokushisa okuphezulu, ukuvimbela ukushisa, ukuvimbela ukushisa kanye nokulinda ilangabi. Lungenye yezinto zokusetshenziswa ezisetshenziswa kabanzi embonini yokumelana nomlilo.

Ukusebenza okuhle kakhulu kanye nokusetshenziswa kwama-bead antantayo

Ukumelana nomlilo okuphezulu. Izakhi eziyinhloko zamakhemikhali zobuhlalu obuntantayo yi-oxides ye-silicon ne-aluminium, i-silicon dioxide engaba ngu-50-65% kanye ne-aluminium trioxide engaba ngu-25-35%. Ngoba iphuzu lokuncibilika kwe-silicon dioxide liphezulu njengo-1725 degrees Celsius, kanti iphuzu lokuncibilika kwe-aluminium oxide lingu-2050 degrees Celsius, zombili eziyizinto eziphikisayo kakhulu. Ngakho-ke, ubuhlalu obuntantayo bunokumelana nomlilo okuphezulu kakhulu, ngokuvamile bufinyelela ku-1600-1700 degrees Celsius, okwenza kube yizinto ezinhle kakhulu eziphikisayo ezisebenza kahle kakhulu. Zilula, zivikela futhi zivikela. Udonga lobuhlalu obuntantayo luncane futhi lungenalutho, lune-vacuum encane ngaphakathi kwesikhala kanye negesi encane kakhulu (i-N2, i-H2, i-CO2, njll.), okuholela ekuqhutshweni kokushisa okuhamba kancane kakhulu futhi okuncane kakhulu. Ngakho-ke ubuhlalu obuntantayo abugcini nje ngokuba lula (ngesisindo seyunithi esingu-250-450 kilograms/m3), kodwa futhi bunokushisa okuhle kakhulu kanye nokushisa (ngokushisa okuhambayo okungu-0.08-0.1 ekushiseni kwegumbi), okubeka isisekelo samandla abo amakhulu emkhakheni wezinto zokushisa ezilula. Ubulukhuni namandla aphezulu. Njengoba ubuhlalu obuntantayo buyingilazi eqinile eyakhiwe yi-silicon aluminium Oxide mineral phase (quartz kanye ne-mullite), ubulukhuni bayo bungafinyelela ku-Mohs 6-7, amandla okucindezela okungaguquki angafinyelela ku-70-140MPa, kanti ubukhulu bayo bangempela bungu-2.10-2.20g/cm3, okulingana nobedwala. Ngakho-ke, ubuhlalu obuntantayo bunamandla aphezulu. Ngokuvamile, izinto ezithambile noma ezingenalutho ezifana ne-Perlite, idwala elibilisayo, i-diatomite, i-pumice, i-vermiculite enwetshiwe, njll. zinobunzima namandla aphansi. Imikhiqizo yokushisa noma imikhiqizo yokukhanya ephikisayo eyenziwe ngazo inobuthakathaka bamandla aphansi. Ubuthakathaka bazo bungukuqina kwamahlalu antantayo, okubanika inzuzo yokuncintisana kanye nobubanzi bokusetshenziswa. Usayizi wezinhlayiya ezincane kanye nendawo enkulu yobuso obuthile. Usayizi wezinhlayiya zemvelo wobuhlalu obuntantayo usukela kuma-micron ayi-1 kuya kwangu-250. Indawo ethile yobuso ingu-300-360cm2/g, okufana nesamente. Ngakho-ke, ubuhlalu obuntantayo abudingi ukugaywa futhi bungasetshenziswa ngqo. Ubuncane bungahlangabezana nezidingo zemikhiqizo ehlukahlukene. Ezinye izinto zokuvikela ukushisa ezilula ngokuvamile zinobukhulu bezinhlayiya ezinkulu (njengePerlite). Uma zigaywa, umthamo uzokhushulwa kakhulu futhi ukuvikela ukushisa kuzoncishiswa kakhulu. Kulokhu, ubuhlalu obuntantayo bunezinzuzo. Ukuvikela kagesi okuhle kakhulu. Ukuvikela okuntantayo ngemva kokukhetha ubuhlalu obunamandla kuyisithako esihle kakhulu sokuvikela esingahambisi ugesi. Ukumelana kwama-insulator ajwayelekile kuyancipha ngokushisa okwandayo, kuyilapho ukumelana kwama-ascent okuntantayo kukhuphuka ngokushisa okwandayo. Le nzuzo ayinazo ezinye izinto zokuvikela. Ngakho-ke, ingasetshenziswa ukukhiqiza imikhiqizo yokuvikela ngaphansi kwezimo zokushisa eziphakeme.
