Momwe Kupukuta Kwamagetsi Kumapangira Malo "Opanda Kukangana" Pantchito Zaukhondo

Kupukuta ndi magetsi ndi njira yofunika kwambiri yomaliza kuti malo osalala komanso aukhondo apezeke m'mafakitale monga mankhwala, sayansi ya zamoyo, chakudya ndi zakumwa, ndi zipangizo zachipatala. Ngakhale kuti mawu akuti "kupukuta popanda kugwedezeka" ndi ofanana, kupukuta ndi magetsi kumapanga malo okhala ndi kugwedezeka kochepa kwambiri komanso mphamvu zochepa pamwamba, zomwe zimagwira ntchito "zopanda kugwedezeka" kwa zinthu zodetsa, tizilombo toyambitsa matenda, ndi madzi.

Nayi njira yofotokozera mwatsatanetsatane momwe imagwirira ntchito komanso chifukwa chake ndi yoyenera kugwiritsidwa ntchito paukhondo:

Kodi Electropolishing ndi chiyani?

Kupukuta ndi electrochemical ndi njira yamagetsi yomwe imachotsa wosanjikiza woonda, wolamulidwa wa zinthu (nthawi zambiri 20-40µm) kuchokera pamwamba pa chitsulo, makamaka zitsulo zosapanga dzimbiri za austenitic (monga 304 ndi 316L). Chigawocho chimagwira ntchito ngati anode (+) mu bafa ya electrolytic (nthawi zambiri chisakanizo cha sulfuric ndi phosphoric acid). Mphamvu ikagwiritsidwa ntchito, ma ayoni achitsulo amasungunuka kuchokera pamwamba kupita ku electrolyte.

 Njira Yowongolerera Yokhala ndi Masitepe Awiri

1. Kusanja kwa Macro (Kusanja kwa Anodic):

· Kuchulukana kwa magetsi kumakhala kwakukulu pamwamba (malo okwera a microscopic) ndi m'mphepete kuposa m'zigwa chifukwa cha kuyandikira kwa cathode.

· Izi zimapangitsa kuti nsonga za mitengo zisungunuke mofulumira kuposa zigwa, zomwe zimapangitsa kuti pamwamba pa nthaka pakhale bwino komanso kuchotsa mikwingwirima, mabala, ndi zizindikiro za zida zomwe zimapangidwa.

2. Kusalala Kwapang'ono (Kuwala kwa Anodic):

· Pa mlingo wa microscopic, pamwamba pake pali kusakaniza kwa tinthu ta kristalo tosiyanasiyana ndi zinthu zina zomwe zikuphatikizidwa.

· Kupukuta kwamagetsi kumasungunula zinthu zosakhuthala, zopanda mawonekedwe, kapena zopanikizika kaye, ndikusiya pamwamba pake pali kapangidwe kolimba komanso kolimba kwambiri ka kristalo.

· Njira imeneyi imayeretsa pamwamba pa mulingo wa sub-micron, zomwe zimachepetsa kwambiri Surface Roughness (Ra). Malo opukutidwa ndi makina amatha kukhala ndi Ra ya 0.5 - 1.0 µm, pomwe malo opukutidwa ndi magetsi amatha kufika pa Ra < 0.25 µm, nthawi zambiri otsika kufika pa 0.1 µm.

Chifukwa Chake Izi Zimapanga Malo “Oyera” Kapena “Opanda Kukangana”

Kuyerekeza Mwachindunji: Kupukuta kwa Makina vs. Kupukuta kwa Ma Electro

Mapulogalamu Ofunika

· Mankhwala/Zachilengedwe: Ziwiya zoyendetsera ntchito, zofukiza, mizati ya chromatography, mapaipi (machitidwe a SIP/CIP), matupi a ma valve, zolumikizira zamkati za pampu.

· Chakudya ndi Zakumwa: Kusakaniza matanki, mapaipi a mkaka, kupanga mowa, ndi madzi, ndi zolumikizira.

· Zipangizo Zachipatala: Zipangizo zopangira opaleshoni, zida zoikira m'thupi, zosinthira mafupa, cannulae.

· Semiconductor: Zinthu zoyendetsera madzi ndi mpweya zomwe zimakhala zoyera kwambiri.

Chidule

Kupukuta kwamagetsi kumapanga malo aukhondo "osaphwanyika" osati mwa kuwapangitsa kukhala osalala bwino kwenikweni, koma mwa:

1. Kusungunula nsonga zazing'ono ndi zofooka pogwiritsa ntchito magetsi.

2. Kupanga malo ofanana, opanda chilema ndi malo ochepa ochiritsira zinthu zodetsa.

3. Kukulitsa gawo la okosidi losagwira dzimbiri.

4. Kuthandiza kuti madzi azituluka bwino komanso kuti ayeretsedwe bwino.
