Indlela yokuqinisa kunye nokugcinwa ngokuchanekileyo kwezinto ezilahlayo ze-phosphate refractory

I-phosphate castable ibhekisa kwi-castable edityaniswe ne-phosphoric acid okanye i-phosphate, kwaye indlela yayo yokuqinisa inxulumene nohlobo lwe-binder esetyenzisiweyo kunye nendlela yokuqinisa.

I-binder ye-phosphate castable ingaba yi-phosphoric acid okanye isisombululo esixutyiweyo se-aluminium dihydrogen phosphate eveliswa yi-reaction ye-phosphoric acid kunye ne-aluminium hydroxide. Ngokubanzi, i-binder kunye ne-aluminium silicate azisabela kubushushu begumbi (ngaphandle kwesinyithi). Ukufudumala kuyadingeka ukuze kususwe amanzi emzimbeni kwaye kuhlanganiswe i-binder kwaye kudityaniswe umgubo odibeneyo ukuze kufunyanwe amandla kubushushu begumbi.

Xa kusetyenziswa i-coagulant, akufuneki kufudunyezwe, kwaye umgubo we-magnesia ocolekileyo okanye isamente ye-alumina ephezulu inokongezwa ukuze kukhawuleziswe ukujiya. Xa kongezwa umgubo ocolekileyo we-magnesium oxide, usabela ngokukhawuleza kunye ne-phosphoric acid ukuze kwenzeke, nto leyo ebangela ukuba izinto ezichaseneyo ziqine kwaye ziqine. Xa kongezwa isamente ye-aluminate, ii-phosphates ezineempawu ezilungileyo ze-gelling, ii-phosphates eziqulathe amanzi ezifana ne-calcium monohydrogen phosphate okanye i-diphosphate ziyakhiwa. I-hydrogen calcium, njl.njl., ibangela ukuba izinto zijiye kwaye ziqine.

Ukususela kwindlela yokuqinisa izixhobo ezibizwa ngokuba yi-phosphoric acid kunye ne-phosphate refractory castables, kuyaziwa ukuba kuphela xa izinga lokuphendula phakathi kwesamente kunye nee-aggregates ezibizwa ngokuba yi-refractory kunye nee-powders lifanelekile ngexesha lenkqubo yokufudumeza apho kunokwenziwa khona i-refractory castable egqwesileyo. Nangona kunjalo, izinto eziluhlaza ezibizwa ngokuba yi-refractory zingeniswa lula kwinkqubo yokucola, ukugaywa kwebhola kunye nokuxuba. Ziya kusabela kunye ne-cementing agent kwaye zikhuphe i-hydrogen ngexesha lokuxuba, nto leyo eya kubangela ukuba i-refractory castable idumbe, ikhulule isakhiwo kwaye inciphise amandla okuxinzelela. Oku akulunganga kwimveliso ye-phosphoric acid eqhelekileyo kunye ne-phosphate refractory castables.
