Ceramic casting sand for sand 3d printing Featured Image

Spherical Ceramic Sand bakeng sa Foundry

Tlhaloso e Khutšoanyane:

Foundry Ceramic Sand, eo ka botekgeniki e bitsoang "Sintered Ceramic Sand for Foundry", eo hape e bitsoang ceramsite, ceramcast, ke sebopeho se setle sa maiketsetso sa lijo-thollo se entsoeng ka bauxite ea calcined. Litaba tsa eona tse ka sehloohong ke aluminium oxide le Silicon oxide. Lehlabathe la Ceramic, le na le thepa e ntle haholo ho feta ea lehlabathe la silika ho fumana ts'ebetso e ntle ho setsi sa motheo. E na le refractoriness e phahameng, katoloso e nyane ea mocheso, coefficient e ntle ea angular, phallo e ntle haholo, ho hanyetsa ho hoholo ho apara, ho sithabela le ho tšoha ha mocheso, sekhahla se phahameng sa ho khutlisa.

Molemo

● Lehlabathe le Letala. E SIRELETSE tikolohong ha e bapisoa le silica (silicosis) le lehlabathe la zircon
● High refractoriness (＞1800°C)，can be used for casting various materials. There is also no need to use different sand type according to material.
● Sekhahla se phahameng sa ho khutlisa chelete. Ka bobeli Thermal le mochini reclamation. E fana ka bophelo bo bolelele ba mosebetsi le phokotso ea tšebeliso ea lehlabathe.
● Ho senyeha ho hoholo. Sebōpeho se chitja sa lehlabathe la Sintered Ceramic ha le bapisoa le lithollo tse nang le sebopeho sa angular se lumella karohano e bonolo ho tsoa ho likarolo tse lahliloeng le ho putlama ho ntlafalitsoeng ho fellang ka matla a tlase le bokhoni ba ho lahlela.
● Mokelikeli o babatsehang le bokhoni ba ho tlatsa ka lebaka la ho ba chitja.
● Katoloso e tlase ea Thermal le Thermal Conductivity. Litekanyo tsa ho lahla li nepahetse haholoanyane mme conductivity e tlase e fana ka ts'ebetso e ntle ea hlobo.
● Tšebeliso e tlaase ea bongata. Joalo ka ha lehlabathe la maiketsetso le le bobebe ho feta lehlabathe la ceramic le kopantsoeng (lehlabathe la bolo e ntšo), zircon le chromite, le ka fetoha habeli palo ea hlobo ka boima ba yuniti. E ka boela ea sebetsoa habonolo haholo, e boloka litšenyehelo tsa basebetsi le ho fetisetsa matla a motlakase. Leha ho le joalo, tlhokomelo e lokela ho lebisoa ho palo ea tlatsetso ea binder.
● E hloka 40-50% e fokolang ea resin.
● Li-casting li koahetsoe ka liphahlo tse nyenyane kapa li se na letho.
● E ka sebelisoa e le lehlabathe le le leng.
● Phepelo e tsitsitseng. Bokhoni ba selemo ba 200,000 MT ho boloka phepelo e potlakileng le e tsitsitseng.

Kopo

Joalo ka thepa e sa nke lehlakore, lehlabathe la ceramic la KAIST le sebetsa ho li-resin tsa acid le alkali.

E ka sebelisoa haholo bakeng sa tšepe e entsoeng ka tšepe, tšepe e entsoeng ka tšepe le tšepe e sa tsitsang, joalo ka ho lahlela foam e lahlehileng, lehlabathe le koahetsoeng, lehlabathe la resin, lebokose le batang la mantlha, ho lahla ka nepo, le khatiso ea 3D.
