Ezinye izixhobo ezijikelezayo kwishishini sele zisebenza kwiqondo lobushushu le-900 ° C ixesha elide. Izinto ezixhathisayo zinzima ukufikelela kwimeko ye-ceramic sintering kule bushushu, echaphazela kakhulu ukusebenza kwezinto eziphikisayo; Iinzuzo zesodium hexametaphosphate kwi-refractory castable kunye nokuzaliswa kwe-spray kukuba inamandla azinzileyo kwaye alungileyo oxinzelelo kunye nokumelana nokunxiba kunye nokuxhatshazwa kwe-thermal. Inceda ukuqinisa ubume bezinto ezidityanisiweyo zezinto eziphikisayo, kwaye inokwenza umgubo okanye i-granular refractory imathiriyeli idityaniswe kunye ukubonisa amandla aneleyo.

Kuphuhliso lwexesha elide lwezixhobo ezijikelezayo, ukuthatha ibhoyila njengomzekelo, ngenxa yesantya solwelo lwamasuntswana okutsha, ubushushu obuphezulu bunokhukuliseko olunamandla kunye nefuthe elinxibileyo kwizinto ezinqandayo ze-lining, ngakumbi igumbi lokutshisa ibhoyila kunye nesahluli sesitshingitshane. kunye nezinye iindawo eziphantsi kokunxitywa kunye nefuthe lokutshatyalaliswa kwe-thermal yamasuntswana, ukuhamba komoya kunye nothuli lweendaba, okukhokelela kukhukuliseko, ukuguga, ukuxobula kunye nokuwa kwe-lining ye-refractory materials. Ichaphazela kakhulu ukusebenza okuqhelekileyo kunye nokuveliswa kwebhoyila.

Ke ngoko, kuyafuneka ukuphuhlisa izibophelelo ezitsha ezinokumelana nobushushu obuphezulu, ukuxhathisa kwe-corrosion, ukumelana nokunxiba kunye nokuxhathisa ukothuka kwe-thermal ukuphucula ukusebenza kwezixhobo ezichasayo.

I-sodium hexametaphosphate ineenzuzo kwi-refractory castable kunye nokuzaliswa kwesitshizi. Ngokukhetha umlinganiselo wokubunjwa kunye neeparitha zenkqubo yokulungiselela, i-binder yinkqubo yokuchithwa kwe-neutral suspension, engenakho ukunamathela okuqinileyo kwaye akukho mhlwa kwi-matrix yensimbi, kodwa inoluhlu olubanzi lobushushu besicelo se-binder ye-inorganic ukumelana nobushushu obuphezulu.

I-sodium hexametaphosphatei-hydrolyzed kwi-sodium dihydrogen phosphate (NaH2PO4) xa isetyenziswa njenge-binder kwi-castables refractory kunye nezitshizi. I-NaH2PO4 kunye ne-alkaline yomhlaba i-oxides yensimbi efana ne-magnesia ilungiselelwe ukuxuba, inokusabela kwiqondo lokushisa kwegumbi ukwenza i-Mg (H2PO4)2. I-Mg(H2PO4)2 ngokukhawuleza yomiswa ukuze yenze i- [Mg(PO3)2]n kunye ne [Mg2(P2O7)]n, ethi inyuse ngakumbi ukomelela kwe-complex kwaye inike amandla amakhulu kuluhlu olubanzi lwamaqondo obushushu (ukuya kuma-800° C) phambi kobukho besigaba solwelo.

Izinto eziphikisayo zibalulekile izinto ezisisiseko zentsimbi kunye nentsimbi, izinto zokwakha, iintsimbi ezingenayo i-ferrous, i-petrochemical, oomatshini, amandla ombane, ukukhuselwa kwendalo kunye nolunye ushishino lobushushu obuphezulu. Ibhondi ye-sodium hempetaphosphate ikwayinto eyimfuneko kuzo zonke iintlobo zobushushu obuphezulu kwishishini le-thermal kiln kunye nezixhobo.
