I-Ceramic Foundry Sand

Isithombe esifakiwe se-Ceramic Foundry Sand

Incazelo emfushane:

I-Al2O3-based Ceramic foundry sand iyisihlabathi sokwenziwa esine-refractoriness enkulu engu-1800 °C. Isihlabathi se-Ceramic foundry sisetshenziswa kakhulu embonini ye-Foundry njenge-molding nesihlabathi esiwumgogodla ngenxa yesimo saso esicishe sibe yindilinga, esihlinzeka ngezakhiwo ezinhle zokugeleza kanye nokungena kwegesi. Ngaphandle kokudela amandla ayisisekelo, kungenzeka ukonga kufikela ku-50% ku-binder ekukhiqizeni okuyinhloko uma kuqhathaniswa nezinye izihlabathi. Ngasikhathi sinye, ukubunjwa okwenziwe ngesihlabathi se-Ceramic kuma-Foundries kunokuphela okuhlukile.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici

• Ukwakheka kwengxenye efanayo
• Ukusatshalaliswa kosayizi wokusanhlamvu okuzinzile kanye nokungena komoya
• I-refractoriness ephezulu (1825°C)
• Ukumelana okuphezulu kokugqoka, ukuchoboza kanye nokushaqeka okushisayo
• Ukunwetshwa okushisayo okuncane
• I-fluidity enhle kakhulu kanye nokusebenza kahle kokugcwalisa ngenxa yokuba yindilinga
• Izinga eliphezulu lokufuna kabusha kusistimu ye-loop yesihlabathi
