Kudalira Ra yokha (kukhwima kwapakati pa malo) sikukwanira poyerekeza electropolishing (EP) ndi mechanical polishing (MP). Ngakhale njira zonsezi zitha kuchepetsa Ra, zimapangitsa kuti pakhale kusiyana kwakukulu pakati pa umphumphu wa malo ndipo, motero, magwiridwe antchito osiyanasiyana kwambiri.
1. Kusiyana Kofunikira mu Njira
• Kupukuta kwa Makina (MP): Njira yodulira yomwe imadula, kupukuta, ndikuchepetsa pamwamba. Imachotsa zinthuzo ndi pulasitiki, ndikusiya gawo logwira ntchito kwambiri komanso lopotoka.
• Kupukuta ndi Electrochemical (EP): Njira yamagetsi yomwe imasungunula mosankha nsonga zazing'ono kwambiri (malo okwera) kuchokera pamwamba mpaka kuzigwa. Imachotsa ayoni ndi ayoni, popanda kupsinjika kwa makina kapena kupopera.
2. Zimene Ra Sakukuuzani
Kupukuta kwa Makina Opangira Mbali
"Thanzi" Pamwamba Pamwamba Pamasiya tinthu tomwe timayabwa, chitsulo chopaka, ming'alu yaying'ono, ndi gawo lozizira kwambiri. Limapanga malo oyera, oyera ngati mankhwala opanda zodetsa kapena gawo lowonongeka.
Kukana Kudzimbiritsa Kungapange ming'alu ndikuswa filimu ya okosijeni yopanda ntchito. Mchenga wophatikizidwa ungayambitse dzenje. Kuchotsa gawo lochepa la chromium ndikuwonjezera pamwamba ndi chromium, ndikupanga filimu yolimba, yofanana yopanda ntchito.
Kuyera ndi Ukhondo Ili ndi mikwingwirima yolunjika mbali ndi zigwa zazing'ono zomwe zimakola mabakiteriya, madzi, ndi tinthu tating'onoting'ono. Imapanga malo osalunjika mbali, osalala, opanda ming'alu omwe ndi osavuta kuyeretsa ndi kuyeretsa (ofunika kwambiri pa mankhwala, chakudya, biotech).
Kugwira Ntchito Motopa Kupsinjika kwa zotsalira ndi zolakwika pamwamba kumachepetsa moyo wotopa. Kumachotsa zinthu zokweza kupsinjika ndi gawo lowonongeka; nthawi zambiri kumawonjezera mphamvu ya kutopa (makamaka mu alloys amphamvu kwambiri).
Ma Geometri Ovuta Sangathe kufikira bwino mabowo amkati, ulusi, ngodya, kapena zinthu zovuta. Amasamalira mofanana malo onse owonekera, kuphatikizapo malo ovuta kufikako, ndi kuchotsa zinthuzo nthawi imodzi.
3. Makhalidwe Abwino a Ra - Msampha
• Kupukuta kwa makina kumatha kufika pa Ra yotsika kwambiri (monga, < 0.05 µm) - koma kusalalako kungakhale kwapamwamba, kubisa pansi pa nthaka yowonongeka.
• Kupukuta kwamagetsi nthawi zambiri kumapereka ma Ra m'magawo a 0.2–0.8 µm, omwe angawoneke ngati "ovuta" poyerekeza ndi manambala. Komabe, pamwamba pake ndi paukhondo wa mankhwala, palibe kupsinjika, komanso pali kukana dzimbiri.
Mu miyezo yambiri (monga ASME‑BPE ya zida zamankhwala), Ra yeniyeni imafunika, koma kupukuta kwamagetsi kumalimbikitsidwa kwambiri chifukwa kumapereka malo opanda mpweya, osati nambala yochepa yokha.
Kutenga Komaliza
Ra ndi nambala chabe - imayesa kusiyana kwa kutalika, osati khalidwe la pamwamba.
Kupukuta ndi kupukuta ndi makina ndi njira zosiyana kwambiri zomwe zimakwaniritsa zolinga zosiyanasiyana. Kusankha koyenera kumadalira zofunikira pa ntchito yanu, osati kutsata Ra yotsika kwambiri.
