Isanti yesiseko seCeramic yenkqubo yesanti eluhlaza

Green Sand Castings are castings made using wet sand or “green sand” molds. The sand is not green in color nor do the molds use “greensand,” a greenish color sandstone. Instead of the sand is called “green” because it has moisture in it (like green wood) before the sand dries out when molten metal is poured in the mold.

What gives the sand moisture and helps the sand stick together when making molds is the clay that is mixed in the sand. Bentonite clay and the sand mixed together provide strong molds that can be created on an automated assembly line.

Isanti yesiseko se-ceramic ye-Sintered yenziwe ikakhulu ngamaminerali aqulethe i-Al2O3 kunye ne-SiO2 kwaye yongezwa kunye nezinye izinto ezimbiwa phantsi. Isanti yesiseko engqukuva eyenziwe ngumgubo, i-pelletizing, i-sintering kunye neenkqubo zokuhlelwa. Isakhiwo sayo esiphambili se-crystal yi-Mullite kunye ne-Corundum, eneenkozo ezijikelezileyo, i-refractoriness ephezulu, ukuzinza okulungileyo kwe-thermochemical, ukwanda kwe-thermal ephantsi, impembelelo kunye nokuchasana kwe-abrasion, iimpawu zokuhlukana okuqinileyo. Xa isanti ye-ceramic isetyenziswa kwinkqubo yesanti eluhlaza, inokunyusa amaxesha esanti ekrwada ephinda isetyenziswe, icuthe ukukhutshwa kwesanti yenkunkuma, kuphuculwe isivuno sokugalela.
