Na'urar taurara da daidaitaccen ajiya na phosphate refractory castables

Castable Phosphate yana nufin simintin da aka haɗe da phosphoric acid ko phosphate, kuma tsarin taurinsa yana da alaƙa da nau'in ɗaure da aka yi amfani da shi da kuma hanyar taurare.

Mai ɗaure na phosphate castable zai iya zama phosphoric acid ko wani gauraye bayani na aluminum dihydrogen phosphate samar da dauki na phosphoric acid da aluminum hydroxide. Gabaɗaya, mai ɗaure da silicate na aluminium ba sa amsawa a cikin ɗaki (sai dai baƙin ƙarfe). Ana buƙatar dumama don bushewa da tara abin ɗaure da haɗa foda tare don samun ƙarfi a zafin jiki.

Lokacin da ake amfani da coagulant, ba a buƙatar dumama, kuma ana iya ƙara foda mai kyau na magnesia ko simintin alumina mai girma don haɓaka coagulation. Lokacin da aka ƙara foda mai kyau na magnesium oxide, yana amsawa da sauri tare da phosphoric acid don samar da shi, yana haifar da abubuwan da ba su da ƙarfi don saitawa da taurare. Lokacin da aka ƙara siminti na aluminate, ana samar da phosphates masu kyaun gelling, phosphates masu ɗauke da ruwa irin su calcium monohydrogen phosphate ko diphosphate. Hydrogen calcium, da dai sauransu, yana sa kayan suyi tauri da taurare.

Daga tsarin hardening na phosphoric acid da phosphate refractory castables, an san cewa kawai lokacin da yawan halayen da ke tsakanin siminti da abubuwan da aka haɗa da foda da foda ya dace a lokacin aikin dumama za'a iya samar da simintin gyaran fuska mai kyau. Duk da haka, ana samun sauƙin kawo kayan da ke jujjuyawa a cikin aiwatar da juzu'a, niƙa ball da haɗuwa. Za su amsa tare da wakilin siminti kuma su saki hydrogen yayin haɗuwa, wanda zai haifar da refractory castable don kumbura, kwance tsarin kuma ya rage ƙarfin matsawa. Wannan ba shi da kyau ga samar da talakawa phosphoric acid da phosphate refractory castables.
