Ukucoca nge-electropolishing yinkqubo ebalulekileyo yokugqiba ukuze kufunyanwe iindawo ezigudileyo nezicocekileyo ezifunekayo kumashishini afana namayeza, i-biotechnology, ukutya neziselo, kunye nezixhobo zonyango. Nangona igama elithi "frictionless" ligama elithelekisekayo, ukucoca nge-electropolishing kudala umphezulu onoburhabaxa obuphantsi kakhulu kunye namandla amancinci omphezulu, oku "kungabi naburhabaxa" ngokusebenzayo kwizinto ezingcolisayo, iintsholongwane, kunye nolwelo.
Nantsi inkcazelo eneenkcukacha zendlela esebenza ngayo kunye nesizathu sokuba ilungele ukusetyenziswa kwezempilo:
Yintoni i-Electropolishing?
I-Electropolishing yinkqubo ye-electrochemical esusa umaleko omncinci, olawulwayo wezinto (ngesiqhelo i-20-40µm) kumphezulu wesinyithi, uninzi lwazo zi-austenitic stainless steels (ezifana ne-304 kunye ne-316L). Le nxalenye isebenza njenge-anode (+) kwi-electrolytic bath (ngesiqhelo umxube we-sulfuric kunye ne-phosphoric acids). Xa kusetyenziswa umbane, ii-ion zesinyithi ziyanyibilika ukusuka kumphezulu ziye kwi-electrolyte.
Indlela Yokuthambisa Enezigaba Ezimbini
1. Ukulinganisa iMacro (Ukulinganisa iAnodic):
· Uxinano lwangoku luphezulu kwiincopho (amanqaku aphezulu e-microscopic) nakwiindawo ezisemacaleni kunakwiintlambo ngenxa yokuba zikufutshane ne-cathode.
· Oku kubangela ukuba iincopho zinyibilike ngokukhawuleza kuneentlambo, kulungelelanisa iprofayili yomphezulu iyonke kwaye kususwe imikrwelo, ii-burrs, kunye neempawu zezixhobo ezivela kwimveliso.
2. Ukuthambisa okuncinci (Ukukhanya kwe-Anodic):
· Kwinqanaba le-microscopic, umphezulu ngumxube wee-crystal grains ezahlukeneyo kunye nezinto eziqukiweyo.
· Ukucoca nge-electropolishing kuqala kunyibilikisa izinto ezingaxinenanga kangako, ezingaguqukiyo, okanye ezixineneyo, kushiye umphezulu olawulwa sisakhiwo sekristale esizinzileyo nesincinci.
· Le nkqubo ilungisa umphezulu kwinqanaba le-sub-micron, inciphisa kakhulu uburhabaxa bomphezulu (Ra). Umphezulu ocociweyo ngoomatshini unokuba ne-Ra ye-0.5 - 1.0 µm, ngelixa umphezulu ocociweyo ngombane unokufikelela kwi-Ra < 0.25 µm, rhoqo uphantsi njenge-0.1 µm.
Kutheni Oku Kudala Umgangatho "Ococekileyo" okanye "Ongenazingxabano"
Uthelekiso oluthe ngqo: Ukupolisha ngoomatshini vs. Ukupolisha ngombane
| Uphawu | Ukupholisha ngoomatshini (Okurhabaxayo) | Ukupholisha nge-electro (i-electrochemical) |
| Iprofayile Yomphezulu | Itshiza kwaye igobe isinyithi phezu kweencopho kunye neentlambo. Ingabamba ukungcola. | Isusa izinto ezikwiincam, ilinganise umphezulu. Akukho zingcolisi zifakwe ngaphakathi. |
| Ukususa iimbumbulu | Isenokungafikeleli kwiindawo zangaphakathi okanye kwi-micro-burrs. | Iphatha ngokulinganayo yonke indawo evezwe ngaphandle, kuquka nejometri zangaphakathi ezintsonkothileyo. |
| Umaleko woMhlwa | Ingadala umaleko obhityileyo, ophazamisekileyo, nongaguquguqukiyo. | Yenza umaleko oqinileyo, ofanayo, noqinileyo we-chromium oxide passive. |
| Umngcipheko wongcoliseko | Umngcipheko wokungena kwe-abrasive media (isanti, ulwelo) kumphezulu. | Umphezulu ococekileyo ngokweekhemikhali; ususa intsimbi efakwe ngaphakathi kunye nezinye iinxalenye. |
| Ukungaguquguquki | Kuxhomekeke kumqhubi; ingahluka kwiindawo ezintsonkothileyo. | Ifana kakhulu kwaye iphinda-phinda yonke indawo. |
Izicelo eziphambili
· I-Pharmaceutical/Biotech: Iinqanawa ze-process, ii-fermenters, iikholamu ze-chromatography, iipayipi (iinkqubo ze-SIP/CIP), imizimba yeevalvu, izinto zangaphakathi zepompo.
· Ukutya Neziselo: Ukuxuba iitanki, imibhobho yobisi, ukwenziwa kwebhiya, kunye neejusi, izixhobo.
· Izixhobo zonyango: Izixhobo zotyando, izinto ezifakelweyo, izinto zokubuyisela amathambo, ii-cannulae.
· I-Semiconductor: Izixhobo zokuphatha ulwelo olucocekileyo kakhulu kunye negesi.
Isishwankathelo
Ukucoca nge-electropolishing kudala umphezulu ococekileyo "ongenazingxabano" kungekuko ngokuwenza ube mpuluswa ngokugqibeleleyo ngokoqobo, kodwa ngoku:
1. Iincopho ezincinci nezingagqibelelanga ezinyibilikiswa ngombane.
2. Ukudala umphezulu ofanayo, ongenaziphene oneendawo ezincinci zokubambelela kwizinto ezingcolisayo.
3. Ukuphucula umaleko we-oxide omelana nokugqwala wendalo.
4. Ukulungiselela ukucoca nokukhupha amanzi ngendlela efanelekileyo.
