Giraangiraha Shiidida Dhoobada ee Alumina ee Birta ah ee loogu talagalay Codsiyada Daloolinta Adkaanta Sare

St.Cera'sgiraanta shiidi alumina ku salaysan birahaWaxay isku daraysaa lakab dhar-xidhka dhoobada ah oo saafi ah (99.8% Al₂O₃) oo leh taageero bir ah oo si sax ah loo farsameeyay (badanaa aluminium ama bir aan miridh lahayn). Naqshaddan isku-dhafka ah waxay bixisaa iska caabin heer sare ah oo xirasho iyo firfircooni la'aan kiimiko ah oo dhoobada ah oo ku taal dusha sare ee shiididda, halka saldhigga birtu uu ku daro xoog farsamo, rakibid fudud, iyo iska caabin jab jab ah. Lakabka alumina wuxuu bixiyaa xoog dabacsan oo ah 361 MPa, adkaanta Vickers ee 16 GPa, iyo xasilloonida kulaylka ilaa 800°C. Saldhigga birta waxaa loo habeeyey godad rakiban, biinanka meelaynta, ama sifooyinka birlabta si loogu daro mashiinnada duubista, shiidiyeyaasha meeraha, iyo qalabka CMP.

Tilmaamaha(Lakabka Alumina oo ku salaysan 99.8% Al₂O₃):

Fiiro gaar ah: Astaamaha saldhigga birta (cufnaanta, module-ka Young, iwm.) laguma bixin jaantusyada walxaha dhoobada ah ee la bixiyay. Waxay raacaan xogta warshadaha ee caadiga ah ee aluminium/birta. Fadlan qeex nooca birta iyo shuruudaha rakibidda.

Codsiyada:

● Giraanta mashiinka lagu shiido meeraha

● Faraantiyada taageerada ee CMP (nadiifinta farsamada kiimikada)

● Si sax ah oo loo dhejiyay shaabado dhoobo ama bir ah

● Qalabka tijaabada xirashada ee xoqan

Habka Wax Soo Saarka:

1. Giraanta dhoobada ah ee Alumina waxaa laga sameeyay 99.8% budo iyo si sax ah loo shiiday ilaa laga gaarayo aqoonsiga/OD-ga kama dambaysta ah iyo fidsanaanta.

2. Saldhigga birta ah waa CNC oo lagu farsameeyay godad lagu dhejiyo, tuubooyin, ama fureyaal.

3. Giraanta dhoobada ah waxaa lagu xiraa saldhig bir ah iyadoo la isticmaalayo epoxy xoog badan (heerkulka adeegga ≤200°C) ama si farsamo ahaan loo xiray (waxay u oggolaanaysaa heerkul sare, ilaa 500°C haddii la isticmaalayo shims bir ah).

4. Dib u dhigista ugu dambeysa ee dusha sare ee dhoobada si loo gaaro fidsanaan iyo dhammaystirka dusha sare ee loo baahan yahay.

5. Nadiifinta Ultrasonic iyo kormeerka cabbirka 100%.

Xakamaynta Tayada:

● Kormeerka CMM ee aqoonsiga, OD, dhumucda, iyo booska godadka

● Cabbiraadda fidsanaan iyadoo la adeegsanayo qalabka laysarka ee interferometer

● Tijaabada xoogga xidhmada (tijaabada jiidista ama jarista ee muunadaha markhaatiga)

● Kormeer muuqaal ah oo ku saabsan dildilaacyada ama godadka lakabka dhoobada ah

Faa'iidooyinka ka badan Giraangadaha Dhoobada ah ama Birta oo Dhan:

● Dusha sare ee dhoobada waxay socotaa 5–10× ka dheer birta adag

● Saldhig bir ah wuxuu bixiyaa dabacsanaan - ma jiro khatar jabitaan ah inta lagu jiro rakibidda

● Si fudud loogu rakibo (godad dunaysan, biinanka dowel) si toos ah loogu dhejiyo mashiinnada jira

● Kharash ka hooseeya giraanta dhoobada oo buuxda ee dhexroorka waaweyn

● Saldhig bir ah ayaa loogu talagalay in lagu xidho birlab birlab ah

Xaddidaadaha (hadallada dhaleeceynta leh):

● Xogta saldhigga birta (ballaarinta kulaylka, adkaanta) ee aan laga helin miisaska dhoobada ee la bixiyay - waxay tixraacaysaa sifooyinka birta caadiga ah.

● Heerkulka ugu badan ee hawlgalka joogtada ah waxaa xaddidaya isku xidhka epoxy (≤200°C ee epoxy-ga caadiga ah; isku xidhka farsamada ayaa u oggolaanaya ilaa 500°C laakiin wuxuu yareeyaa xidhitaanka).

● Kuma habboona deegaannada kiimikada ee gardarrada leh ee weeraraya saldhigga birta (tusaale ahaan, asiidhyada xooggan). Si aad u hesho iska caabin kiimiko oo dhammaystiran, cayim giraanta dhoobada ah oo dhan.

Habayn:

● Walax bir ah: aluminium (fudud), bir aan miridh lahayn (u adkaysta daxalka), ama Invar (ballaarinta kulaylka oo hooseeya)

● Habka isku xidhka: epoxy (≤200°C), qalab farsamo (≤500°C), ama bir-dhalaal ah oo lagu shubay dhoobada (≤800°C, kharash sare)

● Astaamaha rakibidda: godadka dunta leh, godadka biinanka dowel, godadka, ama taageerada birlabta

● Dhumucda lakabka dhoobada ah: 3–20 mm
