Gouden sân foar sân moulding castings

Koarte beskriuwing:

Foundry Ceramic Sand, technysk neamd as "Sintered Ceramic Sand for Foundry", ek neamd as ceramsite, ceramcast, itselde mei cerabeads, guon lannen wurdt ek neamd Golden Sand, is in goede keunstmjittige sfearyske nôtfoarm dy't is makke fan calcined bauxit. Syn wichtichste ynhâld is aluminium okside en silisium okside. Keramyske sân, hat folle bettere eigenskippen as dy fan silika sân om in bettere prestaasjes te krijen yn gieterij. It hat hege refraktoriness, lytse termyske útwreiding, goede hoeke koëffisjint, poerbêst flowability, Hege wjerstân tsjin wear, crush en termyske shock, hege reclamation rate.

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.

Foardiel

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.

Oanfraach

As neutraal materiaal is KAIST keramyske sân fan tapassing op soere en alkali-harsen.

It kin in soad brûkt wurde foar getten izer, getten stiel en non-ferro metalen casting, lykas ferlern foam casting, coated sân, hars sân, kâlde kearn doaze, presys casting, en 3D printsjen.
