Advanced Aluminum Oxide (Al2O3): Kugonesa Mashandisirwo Epamusoro-soro Nekunyatsojeka Uye Kuvimbika
Pfupiso
Aruminiyamu oxide (Al2O3), inozivikanwa se alumina, ipurasitiki inoshandiswa zvakasiyana-siyana uye inoshanda zvakanyanya inoshandiswa zvakanyanya mumaindasitiri akawanda epamusoro nekuda kwesimba rayo re dielectric, kugadzikana kwekupisa, kusagadzikana kwemakemikari, uye kuomarara kwemakanika. Pepa iri rinotsanangura hunhu hwakakosha, mashandisirwo, uye hunyanzvi hwe alumina ine kuchena kwakanyanya, ichitarisa pabasa rayo rakakosha mukurongedza kwe semiconductor uye lithium-ion battery coatings. Pamusoro pezvo, rinoratidza kugona kweUrbanMines Tech., mugadziri anotungamira wekuChina akazvipira kune mhando, kugadzirisa, uye masevhisi ekutumira kunze akavimbika.
1. Nhanganyaya
Alumina haisi chinhu chekugadzira aruminiyamu chete; idombo guru mukugadzirwa kwemazuva ano kwehunyanzvi hwepamusoro. Kubva kuma microelectronics nekuchengetera simba kusvika kuma optics, catalysis, uye ma coatings ekudzivirira, musanganiswa wehunhu hwealumina hunoita kuti ive chinhu chakakosha. Nekukura kuri kuita kudiwa kwe miniaturization, kushanda nesimba, uye kuvimbika kwakanyanya mumasystem emagetsi neesimba, kudiwa kwealumina yakagadzirwa nemazvo kwakakura kupfuura kare.
2. Hunhu hwezvinhu uye Zvirevo
Alumina ine kuchena kwakanyanya inorongwa zvichienderana nechikamu chayo, mwero wekuchena, kugoverwa kwehukuru hwezvidimbu, uye huwandu hwetsvina, parameter imwe neimwe yakagadzirirwa zvinodiwa zvekushandisa.
2.1 Kudzora Kuchena uye Kusachena
- High-Purity Grades: 4N (99.99%), 5N (99.999%), uye 6N (99.9999%) alumina dzakakosha pakushandiswa kwakaoma senge semiconductor encapsulation uye optical components.
- Kubuda kweAlpha-Ray kwakaderera: Zvakakosha pakurongedza kwema semiconductor kudzivirira zvikanganiso zvakapfava mumidziyo yekurangarira. Magadzirirwo anowanzo da huwandu hweUranium (U) neThorium (Th) huri pasi pe3 ppb, nekusvibiswa kushoma kweFe, Na, uye Cl.
- Muenzaniso weChiratidzo:
- Al₂O₃ zviri mukati: ≥ 99.7%
- SiO₂: <0.15%, Fe₂O₃: <0.1%, Na₂O: <0.1%
- Hunyoro: < 0.1%, Kurasikirwa nekupisa: < 0.1%
2.2 Kukura kweZvidimbu uye Maumbirwo azvo
Mashandisirwo anotsanangura granulometry chaiyo:
- Spherical Alumina: Saizi D50 dzinotangira pa1 µm kusvika 45 µm (semuenzaniso, 2.8 µm, 5.8 µm yekuwedzera huwandu hwema packing muma semiconductors).
- Alumina Isina Kutenderera: D50 kubva pa1.5–10.5 µm, inoshandiswa mukupenda uye muzvinhu zvinosanganisa uko nzvimbo chaiyo yepamusoro uye huwandu hwegirini zvakakosha.
- Nzvimbo yeBET: Kazhinji < 1.5 m²/g yekuisa machira kuti pave nechokwadi chekuti slurry yakagadzirwa zvakanaka uye kuti irambe yakanamatira.
2.3 Magadzirirwo echikamu nekristaro
Alpha-phase alumina (α-Al2O3) ndiyo fomu inogara yakasimba pakupisa, ichipa kuomarara kwakanyanya, kufambisa kupisa, uye kudzivirira magetsi. Saizi dzekristaro dze2–3 µm dzinowanzo tsanangurwa kuti dziite sedzinochinja-chinja uye kuti dziite sedzisina kusimba zvakadii.
3. Mashandisirwo Akakosha Mumaindasitiri Epamusoro-soro
3.1 Kurongedza Semiconductor
Alumina ine alpha-spherical inoshandiswa sefiller mu epoxy molding compounds (EMCs) kuwedzera thermal conductivity, kuderedza coefficient of thermal expansion (CTE), uye kupa radiation shield. Kugoverwa kwehukuru hwezvikamu (semuenzaniso, bimodal 2.8 µm uye 5.8 µm) kwakagadzirirwa kurongedza kwakanyanya uye kusimba kushoma.
3.2 Mapeti eLithium-Ion Bhatiri
α-alumina (D50 < 4 µm) inoiswa sejira receramic papolymer separator. Inovandudza kugadzikana kwekupisa, inodzivirira kupinda kwedendrite, uye inowedzera kunyorova kwe electrolyte, nokudaro ichiwedzera kuchengetedzeka kwebhatiri uye hupenyu hwekufamba. Chinhu chacho chinosanganiswa nezvinobatanidza kuti chigadzire slurry yakasimba yejira rakafanana.
3.3 Mamwe Mashandisirwo Epamusoro
- MaCapacitors: Sechipingamupinyi che dielectric nekuda kwemukana wayo wakafara webhendi.
- Kugadzirisa & Kunyudza: Alumina iri panzvimbo yakakwirira sechinotsigira kana kuti desiccant.
- Zviumbwa zveCeramics: Muzvipfeko zvisingapfeki, zvinoiswa muzvipfeko zvekurapa (semuenzaniso, zvinotsiva chiuno), uye masisitimu ezvombo.
- Kupukuta & Kubvisa: Ultrafine alumina (Diamantine) yekupukuta nemazvo muma optics nekugadzira mawachi.
- Kudzivirira kupisa kwakanyanya: Sezvinhu zvinodzivirira kupisa mumaovheni.
4. UrbanMines Tech.: Mubatsiri Akavimbika kubva kuChina
Sezvo kudiwa kwealumina yepamusoro pasi rose kuri kuwedzera, UrbanMines Tech. inoonekwa semutengesi akavimbika ane hunyanzvi hwakadzama uye nzira inotarisa vatengi.
4.1 Hunhu Hwakanaka Mukugadzira
- Mitsetse yedu yekugadzira yakatsaurirwa mukati meChina yakagadzirirwa kugadzira alumina ine alpha shoma uye yakachena uye ine kudzorwa kwakasimba kwemhando.
- Tinopa saizi dzemabatch dzinochinjika—kubva kusampuli dzeR&D kusvika pakugadzirwa kwakazara—tichivimbisa nguva pfupi yekutungamira uye kuwanikwa panguva chaiyo.
4.2 Kugona Kwekugadzirisa
- Tinogadzirisa kuchena, kugoverwa kwehukuru hwezvidimbu, chimiro (chedenderedzwa/chisina denderedzwa), uye ma profiles ekusvibiswa kuti zvienderane nezvinodiwa nevatengi.
- Rutsigiro rwehunyanzvi rwunopihwa kubatsira pakusarudza zvinhu uye kubatanidza.
4.3 Kuvimbika Kwakaratidzwa uye Hunyanzvi Hwekutengesa Zvinhu Kunze Kwenyika
- Nemakore gumi nematanhatu eruzivo muindasitiri, takavaka hukama hwenguva refu; vanopfuura 60% yevatengi vedu vanga vari vadyidzani kwemakore anopfuura mashanu.
- Tine marezenisi ese anodiwa ekutumira kunze kwenyika, kusanganisira ezvigadzirwa zvine chekuita nematombo asina kuchena, tichiona kuti zvinhu zvepasi rose zvinofambiswa zvakanaka uye zvinoenderana nezvinodiwa.
4.4 Kubatsira kwe "Yakagadzirwa muChina"
- Hunhu hwemaindasitiri eChina hwakura hune zvakanakira kukwikwidzana mukutsvaga zvinhu zvisina kugadzirwa, matekinoroji epamusoro ekugadzirisa, uye kugadzirwa kunogona kuwedzerwa.
- UrbanMines Tech. inoshandisa simba iri uku ichitevedzera mitemo yemhando yepamusoro yepasi rose (ISO, RoHS, REACH).
5. Mhedziso
Aluminium oxide yakachena zvikuru inobatsira zvikuru mukugadzira zvinhu zvitsva mumagetsi, kuchengetedza simba, uye zvesimbi zvemhando yepamusoro. Kuzadzisa zvinodiwa zvemazuva ano hakudi sainzi yepamusoro chete asiwo chain yezvigadzirwa yakavimbika uye inochinjika. UrbanMines Tech. inosanganisa zvigadzirwa zvinoshanda zvakanyanya pamwe nekuchinja-chinja uye masevhisi ekutumira zvinhu kunze kwenyika akavimbika, zvichiita kuti ive mubatsiri akakodzera kune vatengi vepasi rose vari kutsvaga mhinduro dzemhando yepamusoro dzealumina.
