Fasika fasika seramika ho an'ny fizotran'ny fasika maitso

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.

Fasika fasika seramika sintetika dia vita amin'ny mineraly misy Al2O3 sy SiO2 ary ampiana akora mineraly hafa. Fasika fasika boribory vita amin'ny vovoka, pelletizing, sintering ary dingana fanasokajiana. Ny firafitry ny kristaly lehibe dia Mullite sy Corundum, miaraka amin'ny endrika voa madinika nahandroina, refractoriness avo, tsara thermochemical fahamarinan-toerana, ambany fanitarana mafana, fiantraikany sy ny abrasion fanoherana, endri-javatra ny fizarazarana mafy. Rehefa ampiharina amin'ny fasika maitso ny fasika seramika, dia mety hampitombo ny fotoana ampiasaina indray ny fasika manta, hampihena ny famoahana fasika fako, hanatsara ny vokatra fanariana.
