Tlhaloso e Khutšoanyane:

Foundry Ceramic Sand, eo ka botekgeniki e bitsoang "Sintered Ceramic Sand for Foundry", eo hape e bitsoang ceramsite, ceramcast, e tšoanang le li-cerabeads, linaha tse ling li boetse li rehiloe Lehlabathe la Khauta, ke sebopeho se setle sa lijo-thollo tsa maiketsetso tse entsoeng ka bauxite ea calcined. Litaba tsa eona tse ka sehloohong ke aluminium oxide le Silicon oxide. Lehlabathe la Ceramic, le na le thepa e ntle haholo ho feta ea lehlabathe la silika ho fumana ts'ebetso e ntle ho setsi sa motheo. E na le refractoriness e phahameng, katoloso e nyane ea mocheso, coefficient e ntle ea angular, phallo e ntle haholo, ho hanyetsa ho hoholo ho apara, ho sithabela le ho tšoha ha mocheso, sekhahla se phahameng sa ho khutlisa.

Molemo

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.
