Phosphate castable inoreva chinhu chinokandwa chakasanganiswa nephosphoric acid kana phosphate, uye kuomesera kwayo kunoenderana nerudzi rwebhainda rinoshandiswa uye nzira yekuomesa.
Iyo binder yephosphate castable inogona kuve phosphoric acid kana yakasanganiswa mhinduro yealuminium dihydrogen phosphate inogadzirwa nekuita kwephosphoric acid uye aluminium hydroxide. Kazhinji, binder uye aluminium silicate hazviiti pamhepo yekushisa (kunze kwesimbi). Kupisa kunodiwa kuti dehydrate uye condense binder uye kubatanidza aggregate poda pamwe chete kuwana simba pakamuri tembiricha.
Kana coagulant ikashandiswa, kupisa hakudiwi, uye yakanaka magnesia poda kana yakakwirira alumina simende inogona kuwedzerwa kuti ikurumidze coagulation. Kana magnesium oxide yakapfava poda yawedzerwa, inobata nekukurumidza nephosphoric acid kuumba, zvichiita kuti zvinhu zvinoramba zvigadzike uye zviome. Apo aluminate simenti inowedzerwa, phosphates ine yakanaka gelling properties, mvura-ine phosphates yakadai se calcium monohydrogen phosphate kana diphosphate inoumbwa. Hydrogen calcium, nezvimwewo, inoita kuti zvinhu zviome uye zviome.
Kubva pakuomeswa kwemaitiro e phosphoric acid uye phosphate refractory castables, zvinozivikanwa kuti chete kana chiyero chekuita pakati pesimende uye refractory aggregates uye hupfu chakakodzera panguva yekudziya inogona kuumbwa yakanakisa refractory castable. Nekudaro, iyo refractory mbishi zvinhu zvinounzwa zviri nyore mukuita pulverization, bhora kugaya uye kusanganisa. Ivo vanozosangana neiyo simende ajenti uye kusunungura hydrogen panguva yekusanganiswa, izvo zvinozoita kuti refractory castable iwedzere, kusunungura chimiro uye kuderedza kusimba kwesimba. Izvi hazvina kunaka pakugadzirwa kweakajairwa phosphoric acid uye phosphate refractory castables.
