Eminye imishini yokujikeleza kwezimboni isikhathi eside ku-900 ℃-1100 ℃ isimo sokushisa somsebenzi, izinto eziphikisayo kuleli zinga lokushisa kunzima ukufeza isimo se-ceramic sintering, kuthinta kakhulu ukusebenza kwezinto eziphikisayo, i-hexametaphosphate ye-sodium ku-castable refractory, fafaza endaweni esebenzayo. ukusebenza kwenzuzo kunamandla azinzile okucindezelayo nokumelana nokugqoka kanye nokumelana nokushaqeka okushisayo, Into esiza ukuqinisa isakhiwo esibophayo ama-refractories, okuvumela ama-powdery noma ama-granular refractories ukuthi ahlangane ukuze abonise amandla anele.
Emishinini yomjikelezo omude okhulayo, i-boiler, ngokwesibonelo, ngenxa yesivinini esivuthayo se-particle fluidization, izinga lokushisa eliphezulu le-refractory yocingo lomlilo linokuguguleka okunamandla, ukuguga, ikakhulukazi ezindaweni ezifana negumbi elivuthayo le-boiler kanye nesihlukanisi sesiphepho ngaphansi kokusanhlamvu, ukugeleza komoya kanye ukuguga okuphakathi kwentuthu kanye nomphumela wokushaqeka okushisayo, kuholela ekugugulekeni kolwelwesi olungaguquki, ukuguga, ukuxebuka nokuwa, kuthinta kakhulu ukusebenza nokukhiqizwa okuvamile. yama-boilers.
Ngakho-ke, kuyadingeka ukuthuthukisa uhlobo olusha lwe-binder olunokumelana nokushisa okuphezulu, ukumelana nokuguguleka, ukumelana nokugqoka kanye nokumelana nokushisa okushisayo ukuze kuthuthukiswe ukusebenza kwezinto eziphikisayo.
I-sodium hexametaphosphate inezinzuzo ekusetshenzisweni kwe-refractory castable, i-spray filler, ngokukhetha isilinganiso sokwakheka kanye nemingcele yenqubo yokulungiselela, i-binder iyisistimu yokumiswa nokuhlakazeka ene-pH engathathi hlangothi, hhayi kuphela ukunamathela okuqinile nokungagqwali ensimbi. i-matrix, ukumelana nezinga lokushisa eliphezulu kanye nebanga lokushisa lesicelo le-non-inorganic binder libanzi. I-sodium hexametaphosphate i-hydrolyzed ibe yi-sodium dihydrogen phosphate (NaH2PO4) uma isetshenziswa njengesibophezelo ku-refractory castable and spray filler.
I-NaH2PO4 kanye ne-alkaline Earth metal oxides, njenge-magnesia, ingasabela ekushiseni kwekamelo ukuze kwakhiwe i-Mg (H2PO4) 2 ne-MgHPO4, engafinyezwa ibe yi-magnesium phosphate [Mg (PO3) 2] N kanye ne-[Mg2 (P2O7)] N ngokulandelanayo ngokushisisa cishe ku-500 ℃. Amandla enhlanganisela athuthukiswa nakakhulu. Inamandla aphezulu phezu kwezinga lokushisa elibanzi (kufika ku-800℃) ngaphambi kokuvela kabusha kwesigaba soketshezi.
I-sodium hexametaphosphate isetshenziswa kakhulu njengesibophezelo sezitini ezingashisiwe ze-magnesia ne-magnesia chrome, izinto ezisansimbi kanye nezinto eziyisisekelo zokugcwalisa. Ekulungiseni okuphonswayo, ukugxila kwesixazululo saso esinamanzi kufanele kukhethwe 25% ~ 30% kufanelekile, kanti inani lokwengeza ngokuvamile liyi-8% ~ 18%. Ngaphansi kwesisekelo sokuqinisekisa ukusebenza kwengxube, kufanele isetshenziswe kancane ngangokunokwenzeka ukuze kuqinisekiswe ukusebenza kokushisa okuphezulu kwento. I-coagulant ingaba usimende we-aluminate noma ezinye izinto eziqukethe i-calcium.
Izinto eziphikisayo ziyizinto ezibalulekile eziyisisekelo zensimbi nensimbi, izinto zokwakha, izinsimbi ezingenayo insimbi, i-petrochemical, imishini, amandla kagesi, ukuvikelwa kwemvelo kanye nezinye izimboni ezisezingeni eliphezulu lokushisa. I-sodium hexametaphosphate binder iphinde ibe yimpahla ebalulekile ehlukahlukene yeziko nemishini eshisayo yezimboni enezinga lokushisa eliphezulu.
