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.
