Zida - Ceramic

♦Alumina(Al2O3)

Magawo olondola a ceramic opangidwa ndi ZhongHui Intelligent Manufacturing Group (ZHHIMG) amatha kupangidwa ndi zida za ceramic zoyera kwambiri, 92 ~ 97% alumina, 99.5% alumina,> 99.9% alumina, ndi CIP ozizira isostatic kukanikiza.Kutentha kwakukulu kwa sintering ndi makina olondola, kulondola kwa ± 0.001mm, kusalala mpaka Ra0.1, kugwiritsa ntchito kutentha mpaka madigiri 1600.Mitundu yosiyanasiyana ya ceramics ikhoza kupangidwa molingana ndi zofuna za makasitomala, monga: wakuda, woyera, beige, wofiira wofiira, etc. The mwatsatanetsatane mbali ceramic opangidwa ndi kampani yathu ndi kugonjetsedwa ndi kutentha, dzimbiri, kuvala ndi kutchinjiriza, ndipo akhoza amagwiritsidwa ntchito kwa nthawi yayitali kutentha kwambiri, vacuum ndi mpweya wowononga mpweya.

Amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zopangira semiconductor: Mafelemu (bulaketi yaceramic), Substrate (base), Arm/ Bridge(manipulator), , Mechanical Components ndi Ceramic Air Bearing.

AL2O3

Kugwiritsa ntchito zida za aluminiyamu zoyera kwambiri:
1. Amagwiritsidwa ntchito ku zida za semiconductor: ceramic vacuum chuck, kudula disc, kuyeretsa disc, ceramic CHUCK.
2. Zigawo zosinthira zophatikizika: ma chucks ophatikizika, ma disks odulira, ma discs otsuka, makapu owoneka bwino oyendera makapu.
3. LED / LCD lathyathyathya gulu anasonyeza makampani: ceramic nozzle, ceramic kugaya chimbale, LIFT PIN, Pin njanji.
4. Kuyankhulana kwa kuwala, mafakitale a dzuwa: machubu a ceramic, ndodo za ceramic, bolodi loyang'ana mawonekedwe osindikizira a ceramic scrapers.
5. Zigawo zosagwirizana ndi kutentha ndi magetsi: zitsulo za ceramic.
Pakali pano, zoumba za aluminiyamu okusayidi akhoza kugawidwa mu chiyero mkulu ndi zadothi wamba.Mitundu yambiri ya aluminiyamu yoyera ya ceramics imatanthawuza zinthu za ceramic zomwe zili ndi zoposa 99.9% Al₂O₃.Chifukwa cha kutentha kwake mpaka 1650 - 1990 ° C komanso kutalika kwake kwa 1 ~ 6μm, nthawi zambiri amasinthidwa kukhala galasi losakanikirana m'malo mwa platinamu crucible: yomwe ingagwiritsidwe ntchito ngati chubu la sodium chifukwa cha kufalikira kwake komanso kukana dzimbiri. chitsulo cha alkali.M'makampani amagetsi, amatha kugwiritsidwa ntchito ngati zida zotchingira ma frequency amtundu wa IC.Malinga ndi zomwe zili mu aluminiyumu oxide, wamba zotayidwa oxide ceramic mndandanda akhoza kugawidwa mu 99 ceramics, 95 ceramics, 90 ceramics and 85 ceramics.Nthawi zina, zoumba ndi 80% kapena 75% ya okusayidi zotayidwa amatchedwanso wamba zotayidwa okusayidi ceramic mndandanda.Pakati pawo, 99 aluminiyamu okusayidi ceramic zinthu ntchito kupanga mkulu kutentha crucible, chubu ng'anjo yowotcha moto ndi zipangizo kuvala zosagwira, monga mayendedwe ceramic, zisindikizo ceramic ndi mbale valavu.95 aluminiyamu ceramics amagwiritsidwa ntchito makamaka ngati dzimbiri zosamva kuvala mbali.85 ceramics nthawi zambiri imasakanizidwa muzinthu zina, potero kumapangitsa kuti magetsi azikhala ndi mphamvu zamakina.Itha kugwiritsa ntchito molybdenum, niobium, tantalum ndi zisindikizo zina zachitsulo, ndipo zina zimagwiritsidwa ntchito ngati zida zamagetsi zamagetsi.
