Ezinye izixhobo zokujikeleziswa kwemizi-mveliso ixesha elide kwi-900 ℃-1100 ℃ imo yobushushu bomsebenzi, izixhobo eziphikisayo kolu bushushu kunzima ukufikelela kuzo kwi-ceramic sintering state, kuchaphazela kakhulu ukusebenza kwezixhobo eziphikisayo, i-sodium hexametaphosphate kwi-refractory castable, isitshizi kwindawo esebenzayo. ukusebenza kwe-advanteji yinto ezinzileyo yamandla e-compressive elungileyo kunye nokumelana nokunxiba kunye nokuxhathisa ukothuka kwe-thermal, Into enceda ukuqinisa isakhiwo esibophezelayo se-refractories, evumela i-powdery okanye i-granular refractories ukuba idibanise kunye ukubonisa amandla aneleyo.
Kwisixhobo somjikelo omde wokuphuhlisa, ibhoyila, umzekelo, ngenxa yokutshisa i-particulate fluidization velocity, ubushushu obuphezulu be-furnace lining refractory inokhukuliseko oluqinileyo, ukunxiba, ngakumbi kwiindawo ezinjengegumbi lokutsha kwibhoyila kunye nesahluli senkanyamba phantsi kweenkozo, ukuhamba komoya kunye Ukunxiba okuphakathi komsi kunye nefuthe lokothuka kwe-thermal, kukhokelela kukhukuliseko lwe-refractory lining, ukuguga, ukuxobuka kunye nokudilika, Kuchaphazela kakhulu ukusebenza okuqhelekileyo kunye nokuveliswa kweebhoyila.
Ngoko ke, kuyimfuneko ukuphuhlisa uhlobo olutsha lwe-binder kunye nokumelana nokushisa okuphezulu, ukuxhathisa ukukhukuliseka, ukuxhathisa ukunxiba kunye nokumelana nokutshatyalaliswa kwe-thermal ukuphucula ukusebenza kwezinto eziphikisayo.
I-sodium hexametaphosphate ineenzuzo ekusetyenzisweni kwe-refractory castable, isitshizi sokutshiza, ngokukhetha umlinganiselo wokwakheka kunye nenkqubo yokulungiselela iparameters, i-binder yinkqubo yokunqunyanyiswa kunye ne-dispersion enexabiso elingathathi hlangothi le-pH, i-adhesion enamandla kunye ne-non-corrosive kwintsimbi. i-matrix, ukumelana nobushushu obuphezulu kunye ne-non-inorganic binder isicelo soluhlu lobushushu lubanzi.I-sodium hexametaphosphate i-hydrolyzed kwi-sodium dihydrogen phosphate (NaH2PO4) xa isetyenziswa njenge-binder kwi-refractory castable kunye ne-spray filler.
I-NaH2PO4 kunye ne-alkaline yomhlaba i-oxide yensimbi, njenge-magnesia, inokusabela kwiqondo lokushisa ukuze yenze i-Mg (H2PO4) 2 kunye ne-MgHPO4, enokuthi ifakwe kwi-magnesium phosphate [Mg (PO3) 2] N kunye ne- [Mg2 (P2O7)] N ngokulandelanayo ngokufudumeza malunga nama-500℃.Amandla okudibanisa aphuculwa ngakumbi.Inamandla aphezulu kuluhlu olubanzi lobushushu (ukuya kuma-800℃) phambi kokuvela kwakhona kwesigaba solwelo.
I-sodium hexametaphosphate isetyenziswa ikakhulu njengesibophelelo kwi-magnesia kunye ne-magnesia chrome yezitena ezingatshiswanga, izinto zokugalela kunye nemathiriyeli esisiseko yokuzalisa.Ekulungiseleleni i-castable, ukuxinwa kwesisombululo sayo samanzi kufuneka kukhethwe i-25% ~ 30% ifanelekile, kwaye inani lokongezwa ngokubanzi li-8% ~ 18%.Ngaphantsi kwesiseko sokuqinisekisa ukusebenza komxube, kufuneka kusetyenziswe kancinci kangangoko ukuqinisekisa ukusebenza okuphezulu kweqondo lokushisa kwezinto.I-coagulant ingaba yi-aluminate cement okanye ezinye izinto ezine-calcium.
Izinto ezichasayo zizinto ezibalulekileyo ezisisiseko zentsimbi kunye nentsimbi, izinto zokwakha, iintsimbi ezingenayo i-ferrous, i-petrochemical, oomatshini, amandla ombane, ukukhuselwa kwendalo kunye namanye amashishini aphezulu obushushu.Isibophelelo se-sodium hexametaphosphate sikwayinto ebalulekileyo kwizixhobo ezahlukeneyo zobushushu obuphezulu kunye nezixhobo.
