Ubuhlalu be-Drift wuhlobo lwebhola elingenalutho lempukane elingantanta phezu kwamanzi.Inombala ompunga omhlophe, inezindonga ezincane nezingenalutho, nesisindo esilula kakhulu.Iyunithi isisindo 720kg/m3 (sinda), 418.8kg/m3 (ukukhanya), futhi usayizi wezinhlayiyana cishe 0.1mm.Indawo ivaliwe futhi ibushelelezi, ine-conductivity ephansi ye-thermal kanye nokumelana nomlilo okungu-≥ 1610 ℃.Kuyinto enhle kakhulu egcina izinga lokushisa le-refractory, esetshenziswa kabanzi ekukhiqizeni ama-castable angasindi kanye nokumba uwoyela.Ukwakheka kwaKhemikhali kobuhlalu obuntantayo ikakhulukazi i-silicon dioxide ne-aluminium oxide.Inezici zezinhlayiya ezinhle, okungenalutho, isisindo esincane, amandla aphezulu, ukumelana nokugqoka, ukumelana nokushisa okuphezulu, ukufakwa kwe-thermal, ukufakwa kwe-insulation kanye ne-flame retadancy.Ingenye yezinto zokusetshenziswa ezisetshenziswa kakhulu embonini yokumelana nomlilo.

Ukusebenza okuhle kakhulu nokusetshenziswa kobuhlalu obuntantayo

Ukumelana nomlilo okuphezulu.Izingxenye zamakhemikhali eziyinhloko zobuhlalu obuntantayo ama-oxide e-silicon ne-aluminium, ne-silicon dioxide ebalelwa cishe ku-50-65% kanye ne-aluminium trioxide accounting engaba ngu-25-35%.Ngoba indawo yokuncibilika ye-silicon dioxide iphezulu njengo-1725 degrees Celsius, futhi indawo yokuncibilika kwe-aluminum oxide ingu-2050 degrees Celsius, kokubili okuyizinto eziphezulu eziphikisayo.Ngakho-ke, ubuhlalu obuntantayo bunokumelana nomlilo okuphezulu kakhulu, ngokuvamile kufinyelela ku-1600-1700 degrees Celsius, okubenza bube yizinto ezisebenza kahle kakhulu zokuphikisa.I-Lightweight, i-insulated kanye ne-insulated.Udonga lobuhlalu obuntantayo luncane futhi luyizigodi, lune-vacuum encane ngaphakathi komgodi kanye nenani elincane kakhulu legesi (N2, H2, CO2, njll.), okuholela ekuqhutshweni kokushisa okunensa kakhulu nokuncane kakhulu.Ngakho-ke ubuhlalu obuntantayo abuyona nje kuphela i-lightweight (ene-unit weight 250-450 kilograms/m3), kodwa futhi inokweqa okuhle kakhulu nokufakwa kwe-thermal (ene-conductivity yokushisa engu-0.08-0.1 ekamelweni lokushisa), okubeka isisekelo sabo. amandla amakhulu emkhakheni wezinto ezingasindi zokufakelwa.Ubulukhuni obuphezulu namandla.Njengoba ubuhlalu obuntantayo buyingilazi eqinile eyakhiwe yi-silicon aluminium Oxide mineral phase (i-quartz ne-mullite), ukuqina kwayo kufinyelela ku-Mohs 6-7, amandla okucindezela okumile angafinyelela ku-70-140MPa, futhi ukuminyana kwawo kwangempela ngu-2.10-2.20g/cm3 , elilingana nedwala.Ngakho-ke, ubuhlalu obuntantayo bunamandla aphezulu.Ngokuvamile, izinto ezilula ezimbotshana noma ezingenalutho ezifana ne-Perlite, idwala elibilayo, i-diatomite, i-pumice, i-vermiculite enwetshiwe, njll. zinobulukhuni obumpofu namandla.Imikhiqizo ye-thermal insulation noma imikhiqizo ekhanyelayo ekhanyelayo eyenziwe ngayo inesimo esibi samandla angenamandla.Ubuthakathaka babo bunamandla obuhlalu obuntantayo, obubanika inzuzo yokuncintisana kanye nohlu olubanzi lokusebenzisa.Usayizi wezinhlayiyana ezinhle kanye nendawo enkulu ethize.Usayizi wezinhlayiyana zemvelo zobuhlalu obuntantayo usuka ku-1 kuye ku-250 microns.Indawo ethize ingu-300-360cm2/g, efana nosimende.Ngakho-ke, ubuhlalu obuntantayo abudingi ukugaya futhi bungasetshenziswa ngokuqondile.I-fineness ingahlangabezana nezidingo zemikhiqizo ehlukahlukene.Ezinye izinto zokufaka ezishisayo ezingasindi zivame ukuba nosayizi omkhulu wezinhlayiyana (njengePerlite).Uma zigaywe, umthamo uzokwandiswa kakhulu futhi ukufakwa kwe-thermal kuzoncishiswa kakhulu.Mayelana nalokhu, ubuhlalu obuntantayo bunezinzuzo.I-insulation kagesi enhle kakhulu.Ubuhlalu obuntantayo ngemva kokukhetha ubuhlalu obuzibuthe buyinto enhle kakhulu yokuvikela engawuhambisi ugesi.Ukumelana nama-insulators ajwayelekile kuncipha ngokukhuphuka kwezinga lokushisa, kuyilapho ukumelana nobuhlalu obuntantayo kukhula ngokukhuphuka kwezinga lokushisa.Le nzuzo ayinayo ezinye izinto zokufakelwa.Ngakho-ke, ingasetshenziswa ukukhiqiza imikhiqizo yokufakelwa ngaphansi kwezimo zokushisa eziphezulu.
