Phosphate castable zvinoreva castable yakabatana nephosphoric acid kana phosphate, uye mashandiro ayo ekuomesa ane chekuita nerudzi rwebinder inoshandiswa uye nzira yekuomesa.
Chinhu chinosunga phosphate chinogona kusanganiswa ne phosphoric acid kana aluminium dihydrogen phosphate inogadzirwa ne phosphoric acid ne aluminium hydroxide. Kazhinji, chinhu chinosunga aluminium silicate hachisanganisike patembiricha yemumba (kunze kwesimbi). Kupisa kunodiwa kuti mvura inyungudike uye isanganise hupfu hwe aggregate pamwe chete kuti uwane simba patembiricha yemumba.
Kana paine coagulant, hapana chikonzero chekudziisa, uye hupfu hwemagnesia hwakatsetseka kana simende ine alumina yakawanda zvinogona kuwedzerwa kuti kukurumidze kuomeswa kwesimbi. Kana hupfu hwemamagnesium oxide hwakatsetseka hukaiswa, hunokurumidza kusangana nephosphoric acid, zvichiita kuti zvinhu zvinoramba zvichioma uye zviome. Kana simende ine aluminate ikaiswa, maphosphate ane hunhu hwakanaka hwegelling, maphosphate ane mvura akadai secalcium monohydrogen phosphate kana diphosphate anoumbwa. Hydrogen calcium, nezvimwewo, zvinoita kuti zvinhu zviome uye zviome.
Kubva pakushanda kwesimbi dzinoita kuti phosphoric acid nephosphate refractory castables dziome, zvinozivikanwa kuti kana chete chiyero che reaction pakati pesimende ne refractory aggregates nehupfu chakakodzera panguva yekupisa ndipo panogadzirwa simbi inoita kuti refractory castable yakanaka. Zvisinei, zvinhu zvinoita kuti refractory castables zviunzwe zviri nyore mu pulverization, ball milling uye mixing. Zvinoita reactive ne cementing agent uye zvinoburitsa hydrogen panguva yekusanganisa, izvo zvinoita kuti refractory castables izvimbe, ibvise chimiro uye ideredze simba rekumanikidza. Izvi hazvina kunaka pakugadzirwa kwesimbi dzinoita kuti phosphoric acid nephosphate refractory castables dziome.
