Lisebelisoa tse ling tsa potoloho ea liindasteri ka nako e telele ho 900 ℃-1100 ℃ boemo ba mocheso oa mosebetsi, thepa ea refractory mochesong ona ho thata ho fihlella boemo ba sintering ea ceramic, e ama ka botebo ts'ebetso ea lisebelisoa tsa refractory, sodium hexametaphosphate ka refractory castable, fafatsa sebakeng se sebetsang. tshebetso ea molemo ke e tsitsitseng e ntle compressive matla le ho apara ho hanyetsa le mocheso makala a hanyetsa, Ntho e thusang ho matlafatsa e tlamang sebopeho sa. li-refractories, tse lumellang phofo kapa granular refractories ho tlamahana hammoho ho bontša matla a lekaneng.
Ka lisebelisoa tse telele tse ntseng li tsoela pele, boiler, mohlala, ka lebaka la lebelo le tukang la metsi, mocheso o phahameng oa sebōpi o na le khoholeho e matla, ho roala, haholo-holo libakeng tse kang kamore ea ho chesa mollo le karohano ea leholiotsoana tlas'a lijo-thollo, phallo ea moea le ho roala ha mosi oa mahareng le phello ea ho sisinyeha ha mocheso, ho lebisa khoholehong ea lesela le sa tsitsang, ho senyeha, ho putlama le ho putlama, ho ama ts'ebetso e tloaelehileng le tlhahiso. ea boilers.
Ka hona, hoa hlokahala ho hlahisa mofuta o mocha oa binder o nang le mocheso o phahameng oa ho hanyetsa, ho hanyetsa khoholeho, ho hanyetsa ho roala le ho hanyetsa mocheso oa mocheso ho ntlafatsa ts'ebetso ea thepa ea refractory.
Sodium hexametaphosphate e na le melemo ea ho sebelisoa ha refractory castable, spray filler, ka khetho ea tekanyo ea ho hlophisoa le mekhahlelo ea ts'ebetso ea ho lokisetsa, binder ke mokhoa oa ho emisa le oa ho hasana o nang le pH e sa nke lehlakore, eseng feela ho khomarela ka matla le ho se senya tšepe. matrix, ho hanyetsa mocheso o phahameng le mefuta e sa tšoaneng ea mocheso oa mocheso oa kopo e sa sebetseng e pharaletse. Sodium hexametaphosphate e entsoe ka hydrolyzed ho sodium dihydrogen phosphate (NaH2PO4) ha e sebelisoa e le tlamahano ho refractory castable le spray filler.
NaH2PO4 le alkaline earth metal oxides, tse kang magnesia, li ka itšoara ka mocheso oa motsoako ho theha Mg (H2PO4) 2 le MgHPO4, e ka kenngoa ka magnesium phosphate [Mg (PO3) 2] N le [Mg2 (P2O7)] N ka ho latellana. ka ho futhumatsa hoo e ka bang 500 ℃. Matla a motsoako a ntlafatsoa le ho feta. E na le matla a phahameng holim'a mefuta e mengata ea mocheso (ho fihla ho 800 ℃) pele ho hlaha hape mohato oa mokelikeli.
Sodium hexametaphosphate e sebelisoa haholo-holo e le setlamo sa magnesia le magnesia chrome litene tse sa chesoang, li-castable le lisebelisoa tsa motheo tsa ho tlatsa. Ha ho etsoa li-castable, motsoako oa tharollo ea eona ea metsi e lokela ho khethoa 25% ~ 30% e loketse, 'me palo ea ho eketsoa ka kakaretso ke 8% ~ 18%. Tlas'a motheo oa ho etsa bonnete ba hore motsoako o sebetsa hantle, o lokela ho sebelisoa ka hohle kamoo ho ka khonehang ho netefatsa ts'ebetso e phahameng ea mocheso oa thepa. Coagulant e ka ba samente ea aluminate kapa lisebelisoa tse ling tse nang le calcium.
Lisebelisoa tsa refractory ke lisebelisoa tsa bohlokoa tsa motheo bakeng sa tšepe le tšepe, thepa ea mohaho, litšepe tse se nang ferrous, petrochemical, mechine, matla a motlakase, tšireletso ea tikoloho le liindasteri tse ling tse phahameng tsa mocheso. Sodium hexametaphosphate binder hape ke sesebelisoa sa bohlokoa sa bohlokoa bakeng sa libopi le lisebelisoa tse fapaneng tsa mocheso o phahameng oa indasteri.
