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.

Ko te Sand Ceramic Foundry, ko te ingoa "Sintered Ceramic Sand for Foundry", i whakaingoatia ano he ceramsite, cerabeads, ceramcast, ko etahi whenua ko te 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 refractoriness, he iti te roha waiariki, he whakarea koki pai, he pai te rere o te rere, He kaha te atete ki te kakahu, te kuru me te wiariki, te reiti whakaora.

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.
