Ukusetshenziswa kwenqubo ye-ceramic yegobolondo lokunemba kwegobolondo le-ceramic kuthuthukiswe ngokushesha eminyakeni yamuva, kusukela emazinyweni okuqala ebhakede emishini yokwakha kuya ezingxenyeni ezijwayelekile zamanje njengama-valve namapayipi, izingxenye zezimoto kuya ezingxenyeni ze-hardware zamathuluzi, kusukela kunsimbi ekhonjiwe, i-cast carbon steel, ensimbini engagqwali, ehlala isikhathi eside Insimbi eshisayo kanye nama-alloys angeyona ayoni iye yanwetshwa emikhakheni ehlukahlukene yokubunjwa kwesihlabathi sangempela, ukubunjwa kwensimbi nokusakazwa ngokunemba, futhi bathole izinzuzo ezinhle zezomnotho nezenhlalo.
Ngokombono wenqubo yokuphonsa, inqubo yokuphonsa ngokunemba kwegobolondo lesihlabathi se-ceramic isetshenziswe kabanzi emikhakheni emithathu elandelayo:
a. Faka esikhundleni kancane inqubo elahlekile yokusakazwa kwe-wax. Ikakhulukazi okunye ukulingisa okunezimo ezilula nokunye ukulingisa okudinga ama-cores, njll.;
b. Lapho ukukhishwa kwegobolondo lesihlabathi se-quartz kwakusetshenziswe khona ekuqaleni, inqubo yokukhipha ngokunemba kwegobolondo lesihlabathi se-ceramic isetshenziselwa ukuthuthukisa ukuguquguquka kwenqubo;
c. Ama-castings ensimbi amancane ekuqaleni akhiqizwa ubuchwepheshe obujwayelekile besikhunta sesihlabathi athathelwa indawo ubuchwepheshe obusha be-ceramic sand shell mold ukunemba ukuze kuthuthukiswe ikhwalithi yokubunjwa, ukunciphisa ukusetshenziswa kwesihlabathi sokubumba, futhi kuthuthukiswe ukusebenza kahle kokukhiqizwa kokusakazwa.
Eminyakeni yamuva, ukuthuthukiswa kanye nokusetshenziswa kwesihlabathi se-ceramic esihlanganiswe nesihlabathi siye sandisa ngokushesha uhla lwesicelo senqubo yokubunjwa kwegobolondo. Ikakhulukazi ngenxa yokuthi:
1. Inani le-resin elengezwe esihlabathini se-ceramic esihlanganiswe nesihlabathi sincane, amandla nokuqina kuphakeme, isihlabathi esiwumgogodla sinokumanzi okuhle kanye nokukhiqizwa kwegesi encane;
2. Isihlabathi se-Ceramic asithathi hlangothi futhi sine-refractoriness ephezulu, ifanele ukuphonswa kwensimbi ekhonjiwe, insimbi ekhonjiwe (i-carbon steel, insimbi ye-alloy ephakathi nendawo, insimbi engagqwali, insimbi ye-chrome, insimbi ye-manganese) nama-alloys angeyona insimbi;
3. Izinhlayiya zesihlabathi se-Ceramic zinokuqina okukhulu namandla, izinga eliphansi lokuchotshozwa, izinga eliphezulu lokugaywa kabusha, kanye nokukhishwa kwesihlabathi esidala esincane;
4. Ukwandiswa okushisayo kwesihlabathi se-ceramic kuncane, okunganciphisa kakhulu ukuthambekela kokukhipha imithambo;
5. Njengesihlabathi sokwenziwa, isihlabathi se-ceramic sinokusatshalaliswa kosayizi wezinhlayiyana ezibanzi, esilungele izinqubo ezihlukahlukene zokulingisa kanye nezidingo zaso. Uma kusetshenziswa isihlabathi esicolekile, sisenokungena komoya okuphezulu, okusiza ekuthuthukiseni ikhwalithi engaphezulu ye-castings.
