Çäge galyplary üçin altyn çäge

Gysga düşündiriş:

Tehniki taýdan “Dörediji keramiki gum” diýlip atlandyrylýan, keramit, keramkast, kerabad bilen birmeňzeş, käbir ýurtlara “Altyn gum” hem diýilýär, kalsinlenen boksitden ýasalan emeli sferik däne görnüşi. Esasy mazmuny alýumin oksidi we Silikon oksidi. Keramiki gum, guýma önümlerinde has gowy öndürijilik gazanmak üçin kremniniň çägelerinden has gowy häsiýetlere eýe. Highokary refraktorlygy, az ýylylyk giňelmegi, gowy burç koeffisiýenti, ajaýyp akymlylygy, könelmegine ýokary garşylyk, ezmek we termiki zarba, ýokary meliorasiýa tizligi bar.

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.

Üstünlik

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.
