Mowhiti Huri Ukume Alumina i Tautokohia e te Mea Whakarewa mō ngā Mahi Whakamau Pūmau

Te Whare o Hato Ceramowhiti huri alumina whakarewaKa whakakotahi i tētahi paparanga kakahu uku alumina parakore-teitei (99.8% Al₂O₃) me tētahi paparanga konganuku i hangaia kia tino tika (konumohe, kowiri tira rānei te tikanga). Mā tēnei hoahoa ranu ka whakaratohia te ātete kakahu tino pai me te koretake matū o te uku ki runga i te mata huri, i te mea ka tāpirihia e te turanga konganuku te kaha miihini, te ngāwari o te whakairi, me te ātete ki te pakaru pakarukaru. Ka tukuna e te paparanga alumina te kaha piko o te 361 MPa, te pakeke Vickers o te 16 GPa, me te pumau wera tae atu ki te 800°C. Kua whakaritea te turanga konganuku ki ngā kōhao whakairi, ngā pine kimi, ngā āhuatanga aukume rānei hei whakauru ki roto i ngā mīhini huri, ngā huri aorangi, me ngā taputapu CMP.

Ngā Whakatakotoranga(Paparanga alumina i runga i te 99.8% Al₂O₃):

Kia mōhio: Kāore ngā āhuatanga turanga whakarewa (kiato, te modulus a Young, me ētahi atu) i whakaratohia i roto i ngā ripanga rauemi uku kua tukuna. E whai ana ēnei i ngā raraunga ahumahi paerewa mō te konumohe/maitai. Tena koa tohua te momo whakarewa me ngā whakaritenga whakairinga.

Ngā tono:

● Ngā mowhiti huri mīhini huri aorangi

● Ngā mowhiti tautoko CMP (whakakanapa matū)

● Te whakapiri papatahi tika o ngā hiri uku, whakarewa rānei

● Ngā taputapu whakamātautau kakahu whakakoi

Tukanga Hanga:

1. Ka whakakorikoria te mowhiti uku alumina mai i te paura 99.8% ka hurihia kia tino tika ki te ID/OD me te papatahi whakamutunga.

2. He mea miihini CNC te turanga whakarewa me ngā kōhao whakapiri, ngā pū kōhao tatau, ngā ara kī rānei.

3. Ka herea te mowhiti uku ki te turanga whakarewa mā te whakamahi i te epoxy kaha-teitei (te pāmahana ratonga ≤200°C) ka herea rānei mā te mīhini (ka taea te pāmahana teitei ake, tae atu ki te 500°C mēnā he hiri whakarewa).

4. Te whakapiri whakamutunga o te mata uku kia puta ai te papatahi me te āhua mata e hiahiatia ana.

5. Te horoinga ultrasonic me te tirotiro 100% inenga.

Mana Kounga:

● Tirotiro CMM mō te ID, te OD, te matotoru, me ngā tūranga kōhao

● Te ine i te papatahi mā te whakamahi i te ine whakawhiti taiaho

● Whakamātautau kaha here (whakamātautau kutikuti, whakamātautau kutikuti rānei i ngā tauira kaiwhakaatu)

● Tirotiro ā-kanohi mō ngā kapiti, ngā āputa rānei i roto i te paparanga uku

Ngā Painga ki ngā Mowhiti Uku-Katoa, ki ngā Mowhiti Whakarewa-Katoa rānei:

● E 5–10× te roa o te mau o te mata uku i te maitai kua whakapakeketia

● Ka ngāwari te turanga whakarewa – kāore he mōrearea pakarukaru i te wā e tāuta ana

● He māmā te whakairi (ngā kōhao miro, ngā pine tākai) ki runga i ngā mīhini o nāianei

● He iti ake te utu i te mowhiti uku katoa mō ngā diameter nui

● Ka taea te hoahoa i te turanga whakarewa mō te whakapiringa o te pūwero aukume

Ngā Here (ngā kōrero arohaehae):

● Ko ngā raraunga turanga whakarewa (te whānuitanga wera, te pakari) ehara i te mea nō ngā ripanga uku kua tukuna – tirohia ngā āhuatanga whakarewa paerewa.

● Ko te pāmahana mahi tonu mōrahi e whakawhāitihia ana e te here epoxy (≤200°C mō te epoxy paerewa; mā te whakapiri ā-ringa ka taea te tae ki te 500°C engari ka whakaitihia te hiri).

● Kāore e pai mō ngā taiao matū kaha e whakaeke ana i te turanga whakarewa (hei tauira, ngā waikawa kaha). Mō te ātete matū katoa, tohua he mowhiti uku katoa.

Whakaritenga:

● Rauemi whakarewa: konumohe (mama), maitai kore waikura (ātete ki te waikura), Invar rānei (iti te horapa wera)

● Tikanga here: epoxy (≤200°C), he rawhi miihini (≤500°C), he uku-ki-te-konganuku rānei kua paraitia (≤800°C, he utu nui ake)

● Ngā āhuatanga whakairi: ngā kōhao miro, ngā kōhao titi porowhita, ngā mokowā, te papa tautoko aukume rānei

● Te matotoru o te paparanga uku: 3–20 mm
