Te kirikiri koura mo te whakarewa kirikiri

Whakaahuatanga Poto:

Ko te kirikiri Ceramic Foundry, ko te ingoa "Sintered Ceramic Sand for Foundry", he mea whakaingoatia ano he ceramsite, ceramcast, he rite ano ki nga cerabeads, ko etahi whenua e kiia ana ko Golden Sand, he pai te ahua o te witi porowhita i hangaia mai i te bauxite calcined. Ko tana ihirangi matua ko te waikura konumohe me te waikura Silicon. Ko te kirikiri kirikiri, he pai ake nga ahuatanga o te kirikiri kirikiri kia pai ake ai te mahi i roto i te hangahanga. He nui te whakakoi, he iti te roha waiariki, he pai te whakarea koki, he pai te rere, He kaha te atete ki te kakahu, te kuru me te wiariki, te tere o te whakaoranga.

Tohu Hua

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.

Painga

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.

Taupānga

Ka rite ki te rauemi kūpapa, KAIST kirikiri uku he hāngai ki te waikawa me te kapia alkali.

Ka taea te whakamahi whanui mo te maka rino, maka rino me nga konganuku nonferrous e maka ana, penei i te makanga pahuka i ngaro, te kirikiri pani, te kirikiri kapia, te pouaka matua makariri, te whakarewanga tika, me te ta 3D.
