Mimwe michina inotenderera muindasitiri yave ichishanda patembiricha ye900 ° C kwenguva yakareba. Iyo inopikisa zvinhu zvakaoma kusvika kune iyo ceramic sintering pane ino tembiricha, iyo inokanganisa zvakanyanya kuita kwezvimiro zverefractory; Zvakanakira zvesodium hexametaphosphate mune refractory castable uye kupfapfaidza kuzadza ndeyekuti ine yakagadzikana uye yakanaka yekumanikidza simba uye kupfeka kuramba uye kupisa kutyisa kuramba. Inobatsira kusimbisa chimiro chekubatana kwezvinhu zvinoramba, uye inogona kugadzira upfu kana granular refractory zvinhu zvisungo pamwe chete kuratidza simba rakakwana.

Mukukura kwenguva refu kwemidziyo inotenderera, tichitora bhaira semuenzaniso, nekuda kwekumhanya kwemvura yezvimedu zvinopisa, tembiricha yakakwira ine kunyura kwakasimba uye kupera simba pazvinhu zvinomisa lining, kunyanya kamuri yekupisa bhailer uye mhepo inoparadzanisa. uye zvimwe zvikamu pasi pekupfeka uye kupisa kwekuvhunduka kwezvimedu, kuyerera kwemhepo uye guruva media, zvichikonzera kukukurwa, kupera, kupepeta uye kudonha kweiyo lining. refractory zvinhu. Iyo inokanganisa zvakanyanya kushanda kwakajairika uye kugadzirwa kweiyo boiler.

Naizvozvo, zvinodikanwa kuvandudza mabhaidha matsva ane tembiricha yekudzivirira, corrosion resistance, kupfeka kuramba uye kupisa kutyisa kupikisa kuti uvandudze mashandiro ezvinhu zvinoramba.

Sodium hexametaphosphate ine zvakanakira mune refractory castable uye spray filling. Kuburikidza nekusarudzwa kweyero yekuumbwa uye gadziriro yegadziriro parameters, iyo binder is a neutral suspension dispersion system, iyo isina kungoita yakasimba adhesion uye isina ngura kune simbi matrix, asiwo ine hupamhi hwekupisa kwekushandisa kwepamusoro tembiricha inodzivirira inorganic binder.

Sodium hexametaphosphateis hydrolyzed to sodium dihydrogen phosphate (NaH2PO4) kana ichishandiswa sebhainda mune refractory castables uye sprays. NaH2PO4 uye alkaline pasi simbi oxides senge magnesia zvakagadzirirwa kusanganiswa, zvinogona kuita pakudziya kwekamuri kuita Mg(H2PO4)2. Mg(H2PO4)2 inokurumidza kuomeswa kuita [Mg(PO3)2]n uye [Mg2(P2O7)]n, iyo inowedzera kuwedzera simba reiyo yakaoma uye inopa simba rakawanda pamusoro pemhando dzakasiyana dzetembiricha (kusvika ku800°). C) pamberi pekuvapo kwechikamu chemvura.

Refractory zvinhu zvakakosha zvakakosha zvesimbi nesimbi, zvekuvakisa, zvisiri-ferrous simbi, petrochemical, muchina, magetsi emagetsi, kuchengetedza kwezvakatipoteredza uye imwe yakanyanya tembiricha indasitiri. Sodium hempetaphosphate bond zvakare chinhu chakakosha kune ese marudzi emhando yepamusoro tembiricha yeindasitiri yekupisa yekupisa nemidziyo.
