Foundry Ceramic Sand, mwaukadaulo wotchedwa "Sintered Ceramic Sand for Foundry", yemwenso amatchedwa ceramsite, ceramcast, yemweyo ndi cerabeads, mayiko ena amatchedwanso Golden Sand, ndi wabwino kupanga ozungulira njere mawonekedwe amene amapangidwa kuchokera calcined bauxite . Zomwe zili mkati mwake ndi aluminium oxide ndi Silicon oxide. Mchenga wa Ceramic, uli ndi zinthu zabwino kwambiri kuposa mchenga wa silika kuti ugwire bwino ntchito poyambira. Ili ndi refractoriness yayikulu, kukulitsa pang'ono kwamafuta, kokwanira bwino kwa angular, kuyenda bwino kwambiri, Kukaniza kwambiri kuvala, kuphwanya ndi kugwedezeka kwamafuta, kuchuluka kwa kubwezeretsedwanso.

Foundry Ceramic Sand, technically named as “Sintered Ceramic Sand for Foundry”, also named as ceramsite, cerabeads, ceramcast, some countries is also named Golden Sand, is good artificial spherical grain shape which is made from calcined bauxite . Its main content is aluminum oxide and Silicon oxide. Ceramic sand, has much better properties than that of silica sand to gain a better performance in foundry. It has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, High resistance to wear, crush and thermal shock, high reclamation rate.

Ubwino

Kaist ceramic foundry sand is about half as light as zircon and chromite, is about third as light as fused ceramic sand. Compared to these natural sand and other foundry media (the material is able to turn out about twice the number of molds per unit weight). Kaist ceramic foundry sand can deliver mold and core packages with a range of benefits that include higher-strength sand casting packages, with high heat resistance, low thermal expansion, improved final part resolution and a smoother surface finish. It can also be handled very easily, saving labor and transfer power costs. However, the manufacturer recommends paying attention to the amount of binder addition.

Kugwiritsa ntchito

Monga zinthu zosalowerera ndale, mchenga wa ceramic wa KAIST umagwira ntchito ku utomoni wa asidi ndi alkali.

Itha kugwiritsidwa ntchito kwambiri popanga chitsulo choponyedwa, chitsulo choponyedwa ndi zitsulo zopanda chitsulo, monga kuponyera chithovu chotayika, mchenga wokutidwa, mchenga wa utomoni, bokosi lozizira pachimake, kuponyera mwatsatanetsatane, ndi kusindikiza kwa 3D.
