Keramik Schmelz Sand fir gréng Sand Prozess

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.

Sinter Keramik Schmelz Sand ass haaptsächlech aus Mineralstoffer gemaach, déi Al2O3 a SiO2 enthalen a mat anere Mineralmaterialien dobäigesat ginn. E kugelfërmege Schmelzsand gemaach duerch Puder-, Pelletiséierungs-, Sinter- a Gradéierungsprozesser. Seng Haaptkristallstruktur ass Mullite a Corundum, mat ofgerënnter Kärform, héijer Refrakteritéit, gudder thermochemescher Stabilitéit, gerénger thermescher Expansioun, Impakt- a Abrasiounsbeständegkeet, Feature vu staarker Fragmentatioun. Wann de Keramik Sand am grénge Sand Prozess applicated, et kéint de Matière Sand erëmbenotzt mol Erhéijung, Offall Sand Emissiounen reduzéiert, Goss nozeginn verbessert.
