Lisebelisoa tse ling tse potolohang indastering li 'nile tsa sebetsa ka mocheso oa 900 ° C ka nako e telele. Thepa e hanyetsanang e thata ho fihlella boemo ba sintering ea ceramic ka mocheso ona, o amang ka botebo ts'ebetso ea lisebelisoa tsa refractory; Melemo easodium hexametaphosphate ka refractory castable le spray filling ke hore e na le matla a tsitsitseng le a matle a ho hatella le ho roala ho hanyetsa le ho hanyetsa mocheso oa mocheso. E thusa ho matlafatsa sebopeho sa maqhama a thepa ea refractory, 'me e ka etsa hore lisebelisoa tsa phofo kapa granular refractory li kopane ho bontša matla a lekaneng.

Nts'etsopele ea nako e telele ea lisebelisoa tse potolohang, ho nka boiler joalo ka mohlala, ka lebaka la lebelo la metsi la likaroloana tse tukang, mocheso o phahameng o na le khoholeho e matla le phello ea ho roala lisebelisoa tse thibelang lera, haholo-holo kamore e tukang ea boiler le karohano ea leholiotsoana. le likarolo tse ling tse tlas'a ts'ebetso ea ts'oaetso ea mogote ea likaroloana, phallo ea moea le lerōle, e bakang khoholeho, ho senyeha, ho phunya le ho putlama ha lesela. lisebelisoa tsa refractory. E ama ka botebo ts'ebetso e tloaelehileng le tlhahiso ea boiler.

Ka hona, hoa hlokahala ho hlahisa li-binders tse ncha tse nang le mocheso o phahameng oa ho hanyetsa, ho hanyetsa kutu, ho hanyetsa ho roala le ho hanyetsa mocheso oa mocheso ho ntlafatsa ts'ebetso ea thepa ea refractory.

Sodium hexametaphosphate e na le melemo ho refractory castable le spray filling. Ka khetho ea karo-karolelano ea ho hlophisoa le litlhophiso tsa mokhoa oa ho itokisa, setlamo ke mokhoa o sa nkeng lehlakore oa ho fanyeha, o nang le sekhomaretsi se matla le ho se na kutu ho matrix a tšepe, empa hape o na le mefuta e mengata ea mocheso oa mocheso oa mocheso o phahameng o hanyetsanang le inorganic binder.

Sodium hexametaphosphatee hydrolyzed ho sodium dihydrogen phosphate (NaH2PO4) ha e sebelisoa e le tlamahano ho li-castable le li-sprays tse refractory. NaH2PO4 le alkaline earth metal oxides tse kang magnesia li lokiselitsoe ho kopanya, li ka itšoara ka mocheso oa mocheso ho theha Mg(H2PO4)2. Mg(H2PO4)2 haufinyane e omisitsoe ho theha [Mg(PO3)2]n le [Mg2(P2O7)]n, tse eketsang matla a rarahaneng le ho fana ka matla a maholo holim'a mefuta e mengata ea mocheso (ho fihla ho 800°). C) pele ho ho ba teng ha mokelikeli mohato.

Lisebelisoa tsa refractory ke lisebelisoa tsa bohlokoa tsa tšepe le tšepe, lisebelisoa tsa mohaho, litšepe tse se nang ferrous, petrochemical, mechine, matla a motlakase, tšireletso ea tikoloho le indasteri e meng ea mocheso o phahameng. Sodium hempetaphosphate bond hape ke thepa ea bohlokoa bakeng sa mefuta eohle ea sebōpi le lisebelisoa tse futhumatsang tsa indasteri.
