Ihe - Seramiiki

♦Alumina (Al₂O3)

A pụrụ iji ihe ndị dị ọcha nke seramiiki nke ZhongHui Intelligent Manufacturing Group (ZHHIMG) mepụtara mee akụkụ seramiiki dị ọcha, 92 ~ 97% alumina, 99.5% alumina, > 99.9% alumina, na CIP oyi na-etinye n'ime ihe mkpuchi isostatic. Nchacha okpomọkụ dị elu na nhazi ziri ezi, izi ezi nha nke ± 0.001mm, ịdị ire ụtọ ruo Ra0.1, jiri okpomọkụ ruo ogo 1600. Enwere ike ime agba dị iche iche nke seramiiki dịka ihe ndị ahịa chọrọ si dị, dịka: oji, ọcha, beige, ọbara ọbara gbara ọchịchịrị, wdg. Akụkụ seramiiki ziri ezi nke ụlọ ọrụ anyị mepụtara na-eguzogide okpomọkụ dị elu, nchara, iyi na mkpuchi, a pụkwara iji ya ogologo oge na gburugburu ebe okpomọkụ dị elu, ikuku na-abanye na ikuku gas.

A na-eji ya eme ihe n'ọtụtụ ngwa mmepụta semiconductor dị iche iche: Frames (bracket seramiiki), Substrate (base), Arm/Bridge (manipulator), Mechanical Components na Ceramic Air Bearing.

Ngwa nke seramiiki alumina dị ọcha nke dị elu:
1. E tinyere ya na ngwaọrụ semiconductor: ihe mkpuchi seramiiki, diski ịkpụ, diski nhicha, CHUCK seramiiki.
2. Akụkụ mbufe Wafer: ihe eji arụ ọrụ wafer, diski ịkpụ wafer, diski nhicha wafer, iko mmiri nyocha anya.
3. Ụlọ ọrụ ngosi panel dị larịị nke LED / LCD: ihe mkpuchi seramiiki, diski igwe seramiiki, PIN LIFT, PIN rail.
4. Nkwukọrịta anya, ụlọ ọrụ anyanwụ: ọkpọkọ seramiiki, mkpara seramiiki, mbipụta ihuenyo seramiiki.
5. Akụkụ ndị na-anaghị ekpo ọkụ ma na-egbochi ọkụ eletrik: ihe ndị e ji seramiiki mee.
Ugbu a, a pụrụ ikewa seramiiki aluminom oxide n'ime ọcha dị elu na seramiiki nkịtị. Usoro seramiiki aluminom oxide dị elu na-ezo aka na ihe seramiiki nwere ihe karịrị 99.9% Al₂O₃. N'ihi okpomọkụ sintering ya nke ruru 1650 - 1990°C na ogologo nnyefe ya nke 1 ~ 6μm, a na-ahazi ya ka ọ bụrụ iko a gwakọtara agwakọta kama platinum crucible: nke enwere ike iji dị ka ọkpọkọ sodium n'ihi nnyefe ìhè ya na iguzogide nchara na alkali metal. N'ụlọ ọrụ eletrọniki, enwere ike iji ya dị ka ihe mkpuchi ugboro ugboro maka ihe ndị dị na IC. Dịka ọdịnaya dị iche iche nke aluminum oxide si dị, enwere ike kewaa usoro seramiiki aluminom oxide nkịtị n'ime seramiiki 99, seramiiki 95, seramiiki 90 na seramiiki 85. Mgbe ụfọdụ, a na-ekewa seramiiki nwere 80% ma ọ bụ 75% nke aluminum oxide dị ka usoro seramiiki aluminom oxide nkịtị. N'ime ha, a na-eji ihe seramiiki aluminum oxide 99 emepụta ọkpọkọ ọkụ dị elu, nke na-egbochi ọkụ na ihe pụrụ iche na-eguzogide iyi, dị ka bearing seramiiki, seramiiki seramiiki na efere valvụ. A na-ejikarị seramiiki aluminum 95 eme ihe dị ka akụkụ na-eguzogide iyi nke na-eguzogide ire ere. A na-agwakọta seramiiki 85 na ụfọdụ ihe onwunwe, si otú a na-eme ka arụmọrụ eletriki na ike igwe dịkwuo mma. Ọ nwere ike iji molybdenum, niobium, tantalum na ihe mkpuchi ígwè ndị ọzọ, a na-ejikwa ụfọdụ dị ka ngwaọrụ ikuku eletrik.

* A naghị etinye MgO n'ime ngụkọ nke ịdị ọcha nke Al₂O₃.
* Enweghị ntụ ntụ scaling 29.4MPa (300kg/cm²), okpomọkụ sintering bụ 1600°C.
AES-11 / 11C / 11F: Tinye 0.05 ~ 0.1% MgO, ike sintera dị mma nke ukwuu, yabụ ọ dabara na seramiiki aluminom oxide nwere ịdị ọcha karịa 99%.
AES-22S: E ji njupụta dị elu na obere mbelata nke ahịrị sintering mara ya, ọ dabara na nkedo ụdị slip na ngwaahịa ndị ọzọ buru ibu nwere izi ezi nha achọrọ.
AES-23 / AES-31-03: O nwere njupụta dị elu, thixotropy na obere viscosity karịa AES-22S. A na-eji nke mbụ eme ihe na seramiiki ebe a na-eji nke abụọ eme ihe dị ka ihe na-ebelata mmiri maka ihe ndị na-egbochi ọkụ, nke na-aghọ ihe a ma ama.
