Hajoale, ts'ebeliso ea lisebelisoa tsa refractory e fana ka litšoaneleho tsa litšoaneleho, ts'ebetso, mefuta-futa, ntlafatso, ts'ebetso e phahameng le ts'ebeliso e tlase, mme nts'etsopele ea lisebelisoa tsa refractory e tlameha ho ikamahanya le eona. Tšebeliso easodium hexametaphosphateka thepa refractory e boetse e kopana le litlhoko tse ncha tsa indasteri ea mosebedisi, le tataiso ea ntshetsopele ya thepa refractory, tse kang litšobotsi, kopanyo, tala, tshebediso e tlaase, e le hore ho ikamahanya le maemo a thepa refractory ke ntlha e ka sehloohong ea diversification.
Hona joale, ho hlaha ha lisebelisoa tse sa tšoaneng ho ntse ho ka finyella litlhoko tsa liindasteri tse kholo. Glassy indasteri sodium hetaphosphate qhibiliha butle ka metsing, kahoo sebelisoa e le refractory binder e lokela ho pulverized ka phofo ho potlakisa qhala eona, e ka tsoakane le metsi ka tekanyo efe kapa efe, e le hore thepa refractory bakeng sa ho hanyetsa ha eona molemo oa mollo le ho tsejoa e le thepa. Ka hona, basebelisi ba likhoebo ba ntse ba hloka ho tseba maemo a nepahetseng ha ba khetha thepa:
1. Refractoriness ea thepa
2. Matla a hatellang a thepa
Likhoebo tse ling li khetha lisebelisoa tsa refractory, eseng feela ho nahana ka refractoriness, empa hape le ho hanyetsa le ho hanyetsa mocheso, matla a khatello ea data.
Sodium hexametaphosphateke thepa e ncha ea refractory e nang le thepa e ntle ho phosphate. Botsitso bo botle ba mocheso oa mocheso, matla a phahameng a ho hatella, ho hanyetsa ho bola ha slag le ho hanyetsa tšusumetso, ka mocheso o phahameng o nolofatsang tlas'a mojaro le botsitso ba lik'hemik'hale. Mocheso oa tšebeliso ea eona o ipapisitse le mefuta le maemo a lisebelisoa tse tala, pakeng tsa 1000 ~ 1800 ℃. Joalo ka ha ba bang ba sebelisa lisebelisoa tsa magnesium joalo ka kakaretso ea refractory le phofo, ba bangata ba tla sebelisa indasteri sodium hexametaphosphatejoalo ka setlamo.
Ho phaella moo, e na le linear nako e telele ketane tlhophiso, e leng adsorped ho ea ka holim'a phatsa ke sehlopha qetellong, ha ketane bohareng ha e le hantle ha e amehe ka bonding, e ka fana ka tlatsetso electrostatic repulsion. Mothating ona, a anngoeng ke ho putlama ha moruo, tlhokahalo e fokolang, matla a tlamang a eketseha, tšusumetso ea lintho tse joalo ka lisebelisoa le ts'ireletso ea tikoloho, indasteri e phahameng ea mocheso le indasteri ea refractory e kene mohatong o mocha oa nts'etsopele ea katleho ea phetisetso ea batho ba bangata, ho ikamahanya le maemo ho thepa e tala ea refractory. hape e behile kopo e ncha, ho feta moetlosodium hexametaphosphatejoalo ka binder e ka sebelisoa tikolohong ea mocheso o phahameng o khethoa hantle, phello ea sebele le tsoelo-pele.
