Ukuphonsa kwesihlabathi: Ukuphonsa kwesihlabathi okuvame ukusetshenziswa embonini ye-valve kungahlukaniswa ngezinhlobo ezahlukahlukene zesihlabathi ezinjengeisihlabathi esimanzi, isihlabathi esomile, isihlabathi sengilazi yamanzi kanye ne-furan resin nesihlabathingokwezibopho ezahlukahlukene.
(1) Isihlabathi esiluhlaza yindlela yokubumba inqubo lapho i-bentonite isetshenziswa khona njenge-binder emsebenzini. Izici zalo yilezi: Isihlabathi esiqediwe asidingi ukomiswa noma ukwelashwa okuqinile, isikhunta sinamandla esimanzi, futhi i-sand core kanye negobolondo linemvume engcono yokuhlanza nokuwa kwesihlabathi. Ukusebenza kahle kokukhiqiza kuphezulu, umjikelezo wokukhiqiza mfushane, futhi izindleko ezibonakalayo nazo ziphansi, okulungele ukuhlela ukukhiqizwa komugqa womhlangano. Okubi kwalo yilezi: Ama-Castings athambekele ekulimaleni okufana nama-pores, ukufakwa kwesihlabathi, kanye nesihlabathi esinamathelayo, kanye nekhwalithi yokukhokhwa, ikakhulukazi ikhwalithi yangaphakathi, ikakhulukazi ikhwalithi yangaphakathi, ikakhulukazi ikhwalithi yangaphakathi, ikakhulukazi ikhwalithi yangaphakathi, ikakhulukazi.
(2) Isihlabathi esomile inqubo yokumodela esebenzisa ubumba njenge-binder, futhi i-bentonite encane ingathuthukisa amandla ayo amamanzi. Izici zalo yilezi: Isigaxa sesihlabathi sidinga ukomiswa, sine-Air Permeability nokuhlakazeka komoya, akulula ukukhiqiza izici ezinjengokugeza isihlabathi, ukunamathela kwesihlabathi, kanye nekhwalithi yangaphakathi yokuphonsa nakho okuhle. Okubi kwayo yilezi: Imishini yokumisa isihlabathi iyadingeka, futhi umjikelezo wokukhiqiza mude.
(3) Isihlabathi se-sodium silisa iyinqubo yokubumba inqubo esebenzisa ingilazi yamanzi njenge-binder. Izici zalo yilezi: Ingilazi yamanzi inomsebenzi wokukwazi ukwenza lukhuni ngokuzenzakalelayo ngemuva kokubhekana nokuhlangabezana nezinzuzo ze-CO2, futhi lungaba nezinzuzo ezahlukahlukene zemodeli yokuqinisa igesi nokwenza okusemqoka. Kodwa-ke, kukhona ababi abanjengobunzima begobolondo, ubunzima ekuhlanzeni kwesihlabathi, kanye nezinga eliphansi lokuvuselela kabusha kwesihlabathi esisetshenzisiwe.
. Emazingeni okushisa ekamelo, isihlabathi sokubumba selashwa ngenxa yokusabela kwamakhemikhali kwe-binter ngaphansi kwesenzo somenzeli olapha. Izici zalo yilezi: Isihlabathi isikhunta asidingi ukomiswa, okunciphisa kakhulu umjikelezo wokukhiqiza futhi kusindise amandla. I-Resin yokubumba isihlabathi kulula kakhulu ukuyixazulula futhi ine-collaplity enhle, futhi isihlabathi sokubumba singahlanzwa kalula, ukunemba okubucayi kungahle kuhlanzeke, futhi ukuqeda okuphezulu kungcono kakhulu, okungathuthukisa kakhulu ikhwalithi yokukhokhiswa. Okubi kwayo yilezi: Izidingo zekhwalithi zesihlabathi esiluhlaza nazo ziphezulu, indawo yokukhiqiza inephunga elicasulayo kancane, nezindleko ze-resin nazo ziphezulu. Inqubo yokuxuba i-furnin resin ukuzilondla isihlabathi esizinzileyo Hlanganisa futhi usebenzise nganoma yisiphi isikhathi. Ukuhleleka kokungeza izinto ezahlukahlukene eziluhlaza lapho ukuxubana i-resin isihlabathi kungokulandelayo: Isihlabathi sokuqala + se-ejenti (ama-ament we-peling (ama-resin + isihlabathi - (60-90) - Isihlabathi (60) - (60-90s) - Isihlabathi (60)
