Kugadzira electropolishing inzira yakakosha yekupedzisa kuti pave nenzvimbo dzakapfava uye dzakachena dzinodiwa mumaindasitiri akadai semishonga, biotechnology, chikafu nezvinwiwa, uye zvishandiso zvekurapa. Kunyange hazvo "kusingapindi" iri izwi rekuti "kupukuta" richireva kuti, kugadzira electropolishing kunogadzira nzvimbo ine roughness shoma uye simba shoma repamusoro, izvo zvinoshanda "zvisingapindi" kune zvinosvibisa, tupukanana, uye mvura.
Heino rondedzero yakadzama yekushanda kwayo uye kuti sei yakanakira kushandiswa mukuchenesa:
Chii chinonzi Electropolishing?
Kuchenesa nemagetsi inzira yemagetsi inobvisa jira rakatetepa, rinodzorwa (rinowanzova 20-40µm) kubva pamusoro pesimbi, kazhinji simbi dzisina kusimba dzinoshandiswa neaustenitic (dzakaita se304 ne316L). Chikamu ichi chinoshanda seanode (+) mubhavhu remagetsi (kazhinji musanganiswa wesulfuric nephosphoric acids). Kana magetsi ashandiswa, maion esimbi anonyungudutswa kubva pamusoro kuenda muelectrolyte.
Nzira Yekutsvedzerera Yematanho Maviri
1. Kuenzanisa Makiro (Kuenzanisa Anodic):
· Kuwanda kwemvura panguva ino kwakakwira pakakwirira (nzvimbo dzakakwirira dze microscopic) uye kumicheto kupfuura mumipata nekuda kwekuva pedyo ne cathode.
· Izvi zvinoita kuti misoro inyungudike nekukurumidza kupfuura mipata, zvichienzanisa chimiro chepamusoro uye zvichibvisa mavanga, maburi, uye mavanga ezvishandiso kubva mukugadzirwa.
2. Kutsvedzerera Kudiki (Kupenya kweAnodic):
· Pachishandiswa microscopic, pamusoro pacho pane musanganiswa wezvimedu zvakasiyana zvekristaro uye zvinhu zvinosanganisirwa.
· Kupukuta nemagetsi kunonyanya kunyungudutsa zvinhu zvisina kusimba, zvisina chimiro, kana kuti zvakamanikidzwa kutanga, zvichisiya pamusoro pacho paine chimiro chakasimba uye chakasimba chekristaro.
· Maitiro aya anogadzirisa pamusoro pechinhu padanho re sub-micron, zvichideredza zvakanyanya Surface Roughness (Ra). Nzvimbo yakakweshwa nemechanically inogona kuva neRa ye 0.5 - 1.0 µm, nepo nzvimbo yakakweshwa nemagetsi inogona kusvika paRa < 0.25 µm, kazhinji yakaderera kusvika pa0.1 µm.
Nei Izvi Zvichigadzira Nzvimbo "Inochengetedza Hutsanana" kana "Isingakanganisi"
Kuenzanisa Kwakananga: Kupukuta Kwemichina vs. Kupukuta Kwemagetsi
| Chinhu | Kukwesha Kwemuchina (Kunokwesha) | Kupolisha kwemagetsi (Electrochemical) |
| Mbiri Yepamusoro | Inoputira nekupeta simbi pamusoro pemakomo nemapani. Inogona kubata tsvina. | Inobvisa zvinhu kubva pamusoro, ichienzanisa pamusoro. Hapana zvinosvibisa zvakaputirwa. |
| Kubvisa mabhatiri | Zvingasasvike pamusoro pemukati kana micro-burrs. | Inogadzirisa zvinhu zvose zvakavhurika zvakaenzana, kusanganisira majometri akaomarara emukati. |
| Rutivi rweKuora | Inogona kugadzira chikamu chakatetepa, chakakanganiswa, uye chisingachinji. | Inogadzira chromium oxide passive layer yakakora, yakafanana, uye yakasimba. |
| Njodzi Yekusvibiswa | Njodzi yekuti zvinhu zvinokuvadza (jecha, matombo) zvipinde pamusoro. | Nzvimbo inocheneswa nemakemikari; inobvisa simbi yakaputirwa nezvimwe zvinhu. |
| Kusachinja-chinja | Zvinoenderana nemushandisi; zvinogona kusiyana muzvikamu zvakaoma. | Yakafanana zvikuru uye inodzokororwa pamusoro pese. |
Zvishandiso Zvikuru
· Mishonga/Biotech: Midziyo yekugadzira, zvinovirisa, makoramu echromatography, mapaipi (SIP/CIP systems), mavharuvhu, zvinhu zvemukati zvepombi.
· Chikafu & Chinwiwa: Kusanganisa matangi, mapaipi emukaka, kubika, uye mitsetse yemuto, zvinhu zvinosungirirwa.
· Midziyo Yekurapa: Zvishandiso zvekuvhiya, zvinhu zvinoisirwa mudumbu, zvinodzoreredza mapfupa, cannulae.
· Semiconductor: Zvikamu zvekushandisa mvura negasi zvine hutsanana hwakanyanya.
Pfupiso
Kuchenesa nemagetsi kunoita kuti nzvimbo yakachena "isina kupwanyika" kwete nekuiita kuti ive yakatsetseka zvakakwana, asi ne:
1. Kunyungudutsa misoro midiki uye kusakwana kwemasero nemagetsi.
2. Kugadzira nzvimbo yakafanana, isina zvikanganiso ine nzvimbo shoma dzekudzivirira tsvina.
3. Kuvandudza ganda remuno rinodzivirira ngura.
4. Kubatsira pakushambidza nekuburitsa mvura zvakanaka.
