Ena mafakitale kufalitsidwa zida kwa nthawi yaitali 900 ℃ -1100 ℃ kutentha boma ntchito, zipangizo refractory pa kutentha ndi zovuta kukwaniritsa ceramic sintering boma, kwambiri zimakhudza ntchito zipangizo refractory, sodium hexametaphosphate mu refractory castable, utsi mu ntchito ntchito ya ubwino ndi khola wabwino compressive mphamvu ndi kuvala kukana ndi matenthedwe mantha kukana, Chinthu chimene chimathandiza kulimbikitsa kumanga dongosolo refractories, kulola powdery kapena granular refractories kugwirizana pamodzi kusonyeza mphamvu zokwanira.
Pazida zazitali zomwe zimapangidwira, boiler, mwachitsanzo, chifukwa cha kuthamanga kwa madzi amadzimadzi, kutentha kwambiri kwa ng'anjo yamoto kumakhala ndi kukokoloka kwamphamvu, kuvala, makamaka m'malo monga chipinda choyatsira moto ndi cholekanitsa chimphepo pansi pambewu, kuyenda kwa mpweya ndi Kusuta sing'anga kuvala komanso kugwedezeka kwamafuta, kumayambitsa kukokoloka kwa zingwe, kutha, kusenda ndi kugwa, kumakhudza kwambiri magwiridwe antchito komanso kupanga ma boilers.
Chifukwa chake, ndikofunikira kupanga mtundu watsopano wa binder wokhala ndi kukana kutentha kwambiri, kukana kukokoloka, kukana kuvala komanso kukana kugwedezeka kwamafuta kuti apititse patsogolo magwiridwe antchito azinthu zotsutsa.
Sodium hexametaphosphate ali ndi ubwino ntchito refractory castable, kutsitsi filler, mwa kusankha zikuchokera chiŵerengero ndi kukonzekera magawo magawo, ndi binder ndi kuyimitsidwa ndi kubalalitsidwa dongosolo ndi ndale pH mtengo, osati amphamvu adhesion ndi sanali dzimbiri zitsulo. matrix, kukana kutentha kwambiri komanso kutentha kosagwiritsa ntchito organic binder ndikokwanira. Sodium hexametaphosphate imapangidwa ndi hydrolyzed kukhala sodium dihydrogen phosphate (NaH2PO4) ikagwiritsidwa ntchito ngati chomangira mu refractory castable ndi spray filler.
NaH2PO4 ndi zitsulo zamchere zamchere zamchere, monga magnesia, zimatha kuchitapo kanthu kutentha kwa firiji kupanga Mg (H2PO4) 2 ndi MgHPO4, yomwe imatha kusinthidwa kukhala magnesium phosphate [Mg (PO3) 2] N ndi [Mg2 (P2O7)] N motero ndi kutentha pafupifupi 500 ℃. Mphamvu ya kuphatikizika imapitilizidwa bwino. Ili ndi mphamvu yayikulu pa kutentha kwakukulu (mpaka 800 ℃) isanayambikenso gawo lamadzimadzi.
Sodium hexametaphosphate imagwiritsidwa ntchito makamaka ngati chomangira njerwa za magnesia ndi magnesia chrome, zoponyera ndi zida zoyambira zowombera. Pokonzekera castable, ndende ya yankho amadzimadzi ayenera kusankhidwa 25% ~ 30% yoyenera, ndi kuchuluka kwa Kuwonjezera zambiri 8% ~ 18%. Pansi pa malo owonetsetsa kuti chisakanizocho chikugwira ntchito, chiyenera kugwiritsidwa ntchito pang'onopang'ono kuti zitsimikizire kutentha kwakukulu kwa zinthuzo. Coagulant ikhoza kukhala simenti ya aluminate kapena zinthu zina zokhala ndi calcium.
Zipangizo zotsutsa ndizofunikira kwambiri pazitsulo ndi zitsulo, zomangira, zitsulo zopanda chitsulo, petrochemical, makina, mphamvu yamagetsi, kuteteza chilengedwe ndi mafakitale ena otentha kwambiri. Sodium hexametaphosphate binder ndiyenso chinthu chofunikira kwambiri pang'anjo ndi zida zotentha kwambiri zamafakitale.
