Umucanga wa zahabu kumucanga

Ibisobanuro bigufi:

Fondasiyo Ceramic Sand, mu buryo bwa tekiniki yitwa "Sintered Ceramic Sand for Foundry", nanone yitwa ceramsite, ceramcast, kimwe na cerabead, ibihugu bimwe na bimwe byitwa Zahabu Sand, ni imiterere yubukorikori nziza yubukorikori ikozwe muri bauxite ibarwa. Ibirimo nyamukuru ni oxyde ya aluminium na Silicon oxyde. Umucanga wa Ceramic, ufite ibintu byiza cyane kurenza umucanga wa silika kugirango ubone imikorere myiza mumushinga. Ifite ubukana bwinshi, kwaguka kwinshi kwubushyuhe, coefficient nziza yinguni, gutembera neza, Kurwanya cyane kwambara, kumenagura no guhungabana, ubushyuhe bwinshi.

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.

Ibyiza

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.

Nibikoresho bidafite aho bibogamiye, umusenyi wubutaka wa KAIST ukoreshwa kuri acide na alkali.

Irashobora gukoreshwa cyane mubyuma bikozwe mucyuma, ibyuma bikozwe mu byuma ndetse n’ibyuma bidafite amabara, nko guta ifuro yatakaye, umucanga usize, umucanga wa resin, agasanduku gakonje gakonje, guta neza, no gucapa 3D.
