Ceramic casting sand for sand 3d printing Featured Image

Bulawan nga balas para sa paghulma sa balas

Mubo nga paghulagway:

Ang Foundry Ceramic Sand, nga teknikal nga ginganlan nga "Sintered Ceramic Sand for Foundry", ginganlan usab nga ceramsite, ceramcast, sama sa cerabeads, ang ubang mga nasud ginganlan usab og Golden Sand, maayo nga artipisyal nga spherical grain nga porma nga gihimo gikan sa calcined bauxite. Ang panguna nga sulud niini mao ang aluminum oxide ug Silicon oxide. Ang seramik nga balas, adunay labi ka maayo nga mga kabtangan kaysa sa silica nga balas aron makakuha usa ka labi ka maayo nga pasundayag sa pandayan. Kini adunay taas nga refractoriness, gamay nga pagpalapad sa thermal, maayo nga angular coefficient, maayo kaayo nga flowability, Taas nga pagsukol sa pagsul-ob, pagdugmok ug thermal shock, taas nga rate sa pagbawi.

Detalye sa Produkto

Mga Tag sa Produkto

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.

Bentaha

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.

Aplikasyon

Ingon nga usa ka neyutral nga materyal, KAIST seramiko balas mao ang magamit sa acid ug alkali resins.

Kini kaylap nga magamit alang sa cast iron, cast steel ug nonferrous metals casting, sama sa nawala nga foam casting, coated sand, resin sand, cold core box, precision casting, ug 3D printing.
