Goue sand vir sand giet gietstukke

Kort beskrywing:

Foundry Ceramic Sand, tegnies genoem as "Sintered Ceramic Sand for Foundry", ook genoem as ceramsite, ceramcast, dieselfde met cerabeads, sommige lande word ook Golden Sand genoem, is 'n goeie kunsmatige sferiese korrelvorm wat gemaak word van gebrande bauxiet. Die hoofinhoud daarvan is aluminiumoksied en silikonoksied. Keramieksand, het baie beter eienskappe as dié van silikasand om 'n beter werkverrigting in gietery te kry. Dit het 'n hoë vuurvastheid, min termiese uitsetting, goeie hoekkoëffisiënt, uitstekende vloeibaarheid, hoë weerstand teen slytasie, druk en termiese skok, hoë herwinningtempo.

Produkbesonderhede

Produk Tags

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.

Voordeel

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.

Toepassing

As 'n neutrale materiaal is KAIST keramieksand van toepassing op suur- en alkaliharse.

Dit kan wyd gebruik word vir gietyster, gegote staal en nie-ysterhoudende metale giet, soos verlore skuim giet, bedekte sand, hars sand, koue kern boks, presisie giet, en 3D druk.
