(Alumina CeramicProduced byWintrustek)
Aluminaizita rinowanzozivikanwa realuminium oxide (Al2O3). Iyo yakasimba tekinoroji ceramic ine yakasarudzika musanganiswa wemakanika uye magetsi maitiro. Inokodzera zvakasiyana-siyana zvekushandiswa kwemaindasitiri.
Core Advantages:
Kugadzira Maitiro: Kubva Paupfu kuenda kune Yakaoma Ceramic
Kugadzira zvemhando yepamusoroalumina ceramic chigadzirwainosanganisira kuchinja kwakaoma kwemuviri nemakemikari:
Kugadzirira kwehupfu: Alumina poda inosanganiswa nekuwedzera (senge sintering aids).
Kugadzira Maitiro: Dry pressing, isostatic pressing, jekiseni molding, kana tepi casting inosarudzwa zvichienderana nechimiro chinodiwa.
Sintering:Izvo zvinhu zvinopiswa muchoto chepamusoro-soro pa 1600 ° C kusvika 1800 ° C, zvichiita kuti zvidimbu zvehupfu zvibatanidze mune dense crystalline structure.
Kupedzisa:Nekuda kwekuomarara kwayo kwakanyanya, kupedzisa mushure mekuita sinter kunowanzoda kushandiswa kwemidziyo yedhaimani kana mavhiri ekukuya.
Ichi chinyorwa chinotarisa pane akati wandei makuru ekugadzira maitiro:
1. Dry Pressing
Iyi ndiyo nzira inonyanya kushandiswa mukugadzirwa kwemaindasitiri, kunyanya yakakodzera kugadzirwa kwakawanda kwemaumbirwo akareruka (semashizha, mhete, uye washer).
Musimboti:Powder ine binder inoiswa musimbi mold uye inoiswa kune unidirectional kana bidirectional pressure uchishandisa muchina.
Zvakanakira: Kushanda kuri nyore, kunyatsoshanda zvakanaka, kuyera kwegirinhi kwemuviri, uye inodzoreka nyore sintering shrinkage.
Kuganhurirwa:Zvakaoma kugadzira zvikamu zvakaoma-zvimiro; nekuda kwekukakavadzana kwemasimba, kuwanda kwezvikamu zvakakura zvinogona kunge zvisina kuenzana.
2. Isostatic Pressing
Kune zvikamu zvepamusoro-soro zvinoda kuwanda kwepamusoro uye kufanana, isostatic kudzvanya ndiyo nzira inosarudzwa.
Musimboti: Iyo hupfu inonamirwa muhutu hunoputika (kazhinji bhegi rerubha) uye inoiswa mumudziyo wepamusoro-soro, uchishandisa mvura semhepo inodzvinyirira.
Core Advantages: Kudzvinyirirwa kunoshandiswa zvakafanana kune hupfu kubva kumativi ose, zvichiita kuti iwedzere kuwirirana mukati memuviri wakasvibirira uye kuderera kuduku mushure mekupisa.
Applications:Inowanzoshandiswa mukugadzira machubhu makuru eceramic, spheres, kana precision ceramic bearings.
3. Tape Casting
Kana iwe ukaona ultra-thin ceramic substrates (senge mabhodhi edunhu munharembozha), iwo anonyanya kugadzirwa nekukanda tepi.
Musimboti:Powder inosanganiswa ne solvent, dispersant, uye binder kuita "slurry," iyo inobva yawaridzirwa pabhandi rekutakura uchishandisa blade yechiremba kugadzira firimu rakatetepa. Iyo firimu inobva yaomeswa uye inosvunurwa.
Zvakanakira: Inokwanisa kugadzira ekupedzisira-akatetepa ceramic masheets ane ukobvu pakati pe10 μm uye 1 mm.
Applications:Gobvu-firimu redunhu substrates, multilayer ceramic capacitors (MLCC).
4. Jekiseni Molding
Iyi nzira, yakakweretwa kubva kuindasitiri yepurasitiki, inoshandiswa kugadzira zvikamu zvine geometries yakaoma kwazvo.
Musimboti:Alumina poda inosanganiswa nehuwandu hukuru hwe organic binder (kusvika pamusoro pe40%), inopisa, uye inobaiwa muforoma chaiyo, yozotonhodzwa uye yaoma.
Zvinetso:Iyo "debinding" process (kubvisa organic matter) isati yaita sintering yakareba uye yakakosha; kubata zvisina kunaka kunogona kutungamirira nyore kutsemuka.
Applications:Ceramic chaiyo zvikamu, zvekurapa mudziyo zvikamu.
5. Additive Manufacturing (3D Printing)
Iyi i tekinoroji yekucheka-kumucheto mumakore achangopfuura iyo inotyora zvachose zvipimo zvakaiswa ne mold pachimiro.
Nzira huru dzinosanganisira: Stereolithography (SLA) kana kuisa extrusion.
Zvakanakira: Hapana molds inodiwa, zvichiita kuti ive yakakodzera kugadzira prototypes kana kugadzira ceramics ine yakanyanya kuomarara zvimiro zvemukati (senge biomimetic skeletons uye microfluidic chips).
