I-Resin Coated Ceramic Sand
Incazelo
Isihlabathi se-ceramic sisetshenziswa esihlabathini sokubumba kanye nesihlabathi esiyinhloko ukwenza isikhunta segobolondo kanye negobolondo legobolondo libe nezindawo zokumelana nokushisa okuphezulu, ukunwetshwa okuphansi, ukuwa kalula, nokukhishwa kwegesi ephansi, okungavimbela ngokuphumelelayo ukukhubazeka kokunwetshwa kokusakazwa.Kuma-cores anezimo eziyinkimbinkimbi ikakhulukazi, angabhekana nenkinga yokuthi ukudubula kwesihlabathi akulula ukuhlanganisa.Kuyisihlabathi se-ceramic esisebenza kwinqubo ye-RCS.
Isihlabathi se-ceramic esigcwele sisetshenziselwa ukwenza isihlabathi esimboziwe, futhi siphinde sisetshenziswe ngokuphindaphindiwe ngemva kokubuyiselwa kabusha, okungathuthukisa ngempumelelo ikhwalithi nokusebenza kahle kokukhiqizwa kokusakazwa, ukunciphisa izinga le-castings scrape kanye nezindleko zokukhiqiza zamabhizinisi, izindleko zokusebenzisa isikhathi eside ziphansi kunalokho. ngesihlabathi se-silica.Ngakho-ke, eminyakeni yamuva, cishe zonke izitshalo zesihlabathi ezimbozwe ngezinga elikhulu ziye zasebenzisa isihlabathi sobumba njengesihlabathi esingavuthiwe ukukhiqiza isihlabathi esimboziwe.
Izici
• I-refractoriness ephakeme—-ukuphonsa izinsimbi ezinezinga lokushisa eliphezulu lokuthela (insimbi ekhonjiwe, insimbi eyingxubevange, insimbi engagqwali, njll.)
• Amandla aphezulu kanye nokuqina—–ukukhiqiza ama-cores ayinkimbinkimbi anezingxenye ezincane.
• Ukwehliswa kwe-thermal ephansi—–ukuze ugweme izinkinga zokunwetshwa.
• Isivuno esiphezulu sokubuyisela kabusha—-ukunciphisa ukulahlwa kwesihlabathi, ukwehlisa izindleko.
• Ukugeleza okuhle kakhulu —–ukwenza ama-cores ayinkimbinkimbi.
• Ukusetshenziswa okuphansi kwe-binder—–ukuvela kwegesi okuphansi, izindleko zokukhiqiza eziphansi.
• Izici zamakhemikhali angasebenzi—–zingasetshenziswa kunoma iyiphi ingxubevange edumile, ehlanganisa insimbi yeManganese.
• Isikhathi eside sokulondoloza.
