Golden sab pou moule sab bòdi

Deskripsyon kout:

Foundry seramik sab, teknikman rele kòm "Sintered seramik sab pou fonderie", tou yo te rele kòm ceramsite, ceramcast, menm ak cerabeads, kèk peyi yo te rele tou Golden Sand, se yon bon fòm atifisyèl grenn esferik ki fèt ak boksit kalsine. Kontni prensipal li se oksid aliminyòm ak oksid Silisyòm. Sab seramik, gen pi bon pwopriyete pase sa yo ki nan sab silica jwenn yon pi bon pèfòmans nan fondri. Li gen gwo refractoriness, ti ekspansyon tèmik, bon koyefisyan angilè, koule ekselan, segondè rezistans nan mete, kraze ak chòk tèmik, to Kominte segondè.

Tags pwodwi

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.

Avantaj

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

Kòm yon materyèl net, sab seramik KAIST aplikab pou rezin asid ak alkali.

Li ka lajman itilize pou jete fè, jete asye ak metal ki pa fè depoze, tankou depoze kim pèdi, sab kouvwi, sab résine, bwat nwayo frèt, Distribisyon presizyon, ak enprime 3D.
