Zlatni pijesak za pješčane kalupe

Kratki opis:

Livački keramički pesak, tehnički nazvan „Sinterovani keramički pesak za livnicu“, takođe nazvan keramzit, keramcast, isto sa cerabolom, u nekim zemljama se naziva i Zlatni pesak, dobar je veštački sferni oblik zrna koji je napravljen od kalcinisanog boksita. Njegov glavni sadržaj je aluminijum oksid i silicijum oksid. Keramički pijesak, ima mnogo bolja svojstva od silicijum pijeska za postizanje boljih performansi u ljevanju. Ima visoku vatrostalnost, malo termičkog širenja, dobar ugaoni koeficijent, odličnu tečnost, visoku otpornost na habanje, gnječenje i termički udar, visoku stopu povrata.

Detalji o proizvodu

Oznake proizvoda

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.

Prednost

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.

Aplikacija

Kao neutralni materijal, KAIST keramički pijesak je primjenjiv na kisele i alkalne smole.

Može se naširoko koristiti za livenje livenog gvožđa, livenog čelika i obojenih metala, kao što je livenje izgubljene pene, obložen pesak, pesak od smole, kutija sa hladnom jezgrom, precizno livenje i 3D štampanje.
