Golden xuab zeb rau xuab zeb molding castings

Lus piav qhia luv luv:

Foundry Ceramic Sand, technically hu ua "Sintered Ceramic Sand for Foundry", kuj muaj npe hu ua ceramsite, ceramcast, tib yam nrog cerabeads, qee lub teb chaws kuj muaj npe hu ua Golden Sand, yog cov khoom zoo nkauj zoo nkauj uas yog tsim los ntawm calcined bauxite. Nws cov ntsiab lus tseem ceeb yog aluminium oxide thiab Silicon oxide. Ceramic xuab zeb, muaj ntau yam zoo dua li ntawm silica xuab zeb kom tau txais kev ua tau zoo hauv kev tsim khoom. Nws muaj refractoriness siab, me ntsis thermal expansion, zoo angular coefficient, zoo heev flowability, siab tsis kam hnav, crush thiab thermal shock, siab reclamation tus nqi.

Product Detail

Khoom cim npe

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.

Qhov zoo

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.

Daim ntawv thov

Raws li cov khoom siv nruab nrab, KAIST ceramic xuab zeb siv tau rau cov kua qaub thiab alkali resins.

Nws tuaj yeem siv dav rau cam khwb cia hlau, cam khwb cia hlau thiab nonferrous hlau casting, xws li poob ua npuas ncauj casting, coated xuab zeb, resin xuab zeb, txias tub ntxhais lub thawv, precision casting, thiab 3D luam ntawv.
