Elektropolishing waa hab dhammaystiran oo muhiim ah si loo gaaro dusha sare ee aadka u siman, nadiifka ah ee looga baahan yahay warshadaha sida daawooyinka, bayotechnoolajiyadda, cuntada iyo cabitaanka, iyo aaladaha caafimaadka. In kasta oo "frictionless" ay tahay erey qaraabo ah, electropolishing wuxuu abuuraa dusha sare oo leh micro-rouness aad u hooseeya iyo tamar dusha sare oo yar, kaas oo si shaqo ahaan "aan la isku hallayn" u ah wasakhda, microbes-ka, iyo dareerayaasha.
Waa kan faahfaahin faahfaahsan oo ku saabsan sida ay u shaqeyso iyo sababta ay ugu habboon tahay codsiyada nadaafadda:
Waa maxay Elektropolishing?
Elektropolishing waa hab elektrochemical ah oo ka saara lakab khafiif ah oo la xakameeyey oo walxo ah (badanaa 20-40µm) dusha birta ah, oo inta badan ah birta aan lahayn ee austenitic (sida 304 iyo 316L). Qaybtu waxay u dhaqantaa sidii anode (+) oo ku jirta qubeyska elektrolytic (badanaa isku darka asiidhyada sulfuric iyo fosfoorik). Marka la mariyo hadda, ayoonnada birta ah ayaa laga milmaa dusha sare una gudba elektrooliktiga.
Habka Simida Labada Marxaladood
1. Heerka Sare (Heer-u-sarraynta Anodic):
· Cufnaanta hadda jirta ayaa ka sarreysa meelaha ugu sarreeya (meelaha sare ee yar yar) iyo geesaha marka loo eego dooxooyinka sababtoo ah u dhowaanshaha cathode-ka.
· Tani waxay keentaa in meelaha ugu sarreeya ay si dhakhso leh u milmaan marka loo eego dooxooyinka, iyadoo simaysa muuqaalka guud ee dusha sare iyo ka saarista xoqidda, burrs-ka, iyo calaamadaha qalabka ee wax soo saarka.
2. Micro-Smoothing (Nalalka Anodic):
· Heer yar oo mikroskoob ah, dusha sare waa isku darka noocyo kala duwan oo ah walxo kiristaal ah iyo walxo ku jira.
· Elektropolishing-ku wuxuu marka hore milmaa walxaha aan cufanayn, aan qaab-dhismeed lahayn, ama kuwa walwalsan, isagoo ka tagaya dusha sare oo ay ku badan yihiin qaab-dhismeedka kristalinta ugu xasilloon, ee isku-dhafan.
· Habkani wuxuu simi doonaa dusha sare heer hoose oo micron ah, isagoo si weyn u yareynaya Roughness-ka Dusha Sare (Ra). Dusha sare ee si farsamo ahaan loo safeeyey waxay yeelan kartaa Ra oo ah 0.5 – 1.0 µm, halka dusha sare ee elektaroonik ahaan loo safeeyey ay gaari karto Ra < 0.25 µm, inta badan waa mid hooseeya ilaa 0.1 µm.
Sababta Tani u Abuurto Dusha "Nadiif ah" ama "aan la isku halleyn karin"
Isbarbardhigga Tooska ah: Nadiifinta Farsamada iyo Elektropolishing
| Muuqaalka | Nadiifinta Farsamada (Xabadaysan) | Nadiifinta Elektrokemikaalka (Electrochemical) |
| Astaanta Dusha Sare | Waxay birta ku xoqdaa oo ku laabataa meelaha dhaadheer iyo dooxooyinka. Waxay qaban kartaa wasakhda. | Waxay ka saartaa walxaha meelaha ugu sarreeya, iyadoo simeysa dusha sare. Ma jiraan wax wasakh ah oo ku dhex jira. |
| Dib u soo celinta | Ma gaari karo dusha sare ee gudaha ama meelaha yaryar. | Si isku mid ah ayuu u daaweeyaa dhammaan dusha sare ee la soo bandhigay, oo ay ku jiraan joomatari gudaha ah oo adag. |
| Lakabka daxalka | Waxay abuuri kartaa lakab khafiif ah, dhib badan, oo aan iswaafaqsanayn. | Waxay abuurtaa lakab qaro weyn, isku mid ah, oo adag oo ah chromium oxide passive layer. |
| Khatarta Wasakhowga | Khatarta ah in walxaha xoqa (ciid, ciid) ay ku soo galaan dusha sare. | Dusha sare ee kiimikada lagu nadiifiyo; waxay ka saartaa birta ku jirta iyo walxaha kale ee wasakhda ah. |
| Joogto ah | Ku-tiirsanaanta Hawl-wadeenka; way kala duwanaan kartaa qaybaha adag. | Aad isugu mid ah oo lagu celin karo dhammaan aagga dusha sare. |
Codsiyada Muhiimka ah
· Farmashiyaha/Bayotechnoolajiyadda: Maraakiibta habaynta, khamiiriyeyaasha, tiirarka koromatografiga, tuubooyinka (nidaamyada SIP/CIP), jidhka waalka, gudaha bamka.
· Cuntada & Cabitaanka: Isku darka haamaha, tuubooyinka caanaha, khaanadaha wax lagu karsado, iyo kuwa casiirka, iyo qalabka lagu rakibo.
· Qalabka Caafimaadka: Qalabka qalliinka, qaybaha qalabka lagu tallaalo, qalabka dib u milicsiga lafaha, qalabka cannulae.
· Semiconductor: Qaybaha dareeraha iyo gaaska ee nadiifka ah.
Soo Koobid
Elektropolishing-ku wuxuu abuuraa dusha nadiif ah oo "aan is khilaafsanayn" ma aha isagoo ka dhigaya mid si fiican u siman macno ahaan, laakiin isagoo:
1. Si elektaroonik ah u milmida meelaha ugu sarreeya ee yar yar iyo cilladaha.
2. Abuuritaanka dusha sare oo siman, oo aan cillad lahayn oo leh barroosin yar oo loogu talagalay wasakhda.
3. Kobcinta lakabka oksaydhka ee u adkaysta daxalka asalka ah.
4. Fududeynta dheecaanka iyo nadiifinta qumman.
