Thaum xaiv cov yeeb nkab stainless hlau rau cov khoom siv uas huv si lossis cov khoom siv tseem ceeb, qhov kev xaiv ntawm BA (Bright Annealed) thiab EP (Electropolished) yog qhov tseem ceeb. Qhov kev txiav txim siab nyob ntawm qib kev huv ntawm qhov chaw, kev tiv thaiv xeb, thiab koj cov peev nyiaj.
· BA (Bright Annealed) Raj:Cov yeeb nkab no raug kho cua sov uas tswj tau hauv huab cua (feem ntau yog siv hydrogen) kom tiv thaiv kev oxidation, ua rau muaj qhov chaw huv si, ci ntsa iab, thiab tsis muaj oxide. Nws ua haujlwm ua cov khoom siv tseem ceeb rau cov yeeb nkab EP.
· EP (Electropolished) Raj:Qhov no yog ib lub raj BA uas tau dhau los ntawm cov txheej txheem electrochemical thib ob. Lub raj raug muab tso rau hauv ib lub dab dej acid thiab raug rau hluav taws xob tam sim no, uas xaiv cov ntsiab lus siab me me (peaks) ntawm qhov chaw hlau. Qhov no tsim kom muaj qhov tiav zoo li daim iav thiab ua kom qhov chaw nplua nuj nrog cov txheej txheem passive nplua nuj chromium.
Tus ntsuas tseem ceeb rau qhov ua tiav ntawm qhov chaw yog Ra (Roughness Average), uas ntsuas qhov nruab nrab ntawm cov ncov me me thiab cov hav dej ntawm ib qho chaw. Cov nqi Ra qis dua qhia tias qhov chaw du dua.
| Cov Qauv | BA (Bright Annealed) Raj | EP (Electropolished) Raj |
|---|---|---|
| Qhov Nto Nto | Ci ntsa iab, cuam tshuam, du | Zoo li daim iav, tsis muaj qhov tsis zoo |
| Ib txwm muaj sab hauv Ra | 0.4-0.8 µm (16-32 µin) | 0.13 - 0.25 µm (5 - 10 µin) |
| Qhov Zoo Tshaj Plaws Ua Tau Ra | ~0.2 – 0.4 µm | ≤ 0.13 µm (5 µin) lossis qis dua |
| Kev tshawb nrhiav saum npoo av | Khaws cov ncov me me, cov hav, thiab cov ciam teb ntawm cov noob | Microscopically planar nrog qhov chaw txo qis heev |
Txawm hais tias Ra qis dua feem ntau qhia tias qhov chaw du dua, qhov chaw ntawm thaj chaw kuj tseem ceeb. Qhov chaw EP nrog Ra ntawm 0.32 µm tuaj yeem muaj qhov sib txawv ntawm qhov siab tshaj plaws mus rau hav qis dua li lub raj xa dej txias nrog Ra qis dua ntawm 0.12 µm, ua rau qhov chaw EP ntxuav tau zoo dua.
·Xaiv EP rau cov ntawv thov ultra-high purity (UHP). Cov txheej txheem electrochemical tshem tawm cov khoom tsis huv uas nkag mus rau hauv, tsim ib txheej chromium-nplua nuj passive, thiab txo cov khoom me me lo rau thiab kev loj hlob ntawm cov kab mob. Nws yog tus qauv rau cov kab ke tseem ceeb ntawm semiconductor, kev hloov pauv kua tshuaj sterile, thiab UHV systems.
·Xaiv BA rau cov kev siv uas muaj kev ntshiab siab tab sis tsis yog cov kev siv uas muaj kev ntshiab siab heev. Nws muab kev huv zoo heev ntawm tus nqi qis dua thiab tsim nyog rau kev faib roj dav dav, cov chaw siv hluav taws xob, thiab cov txheej txheem khoom noj thiab dej haus.
·Cov yeeb nkab EP muab kev tiv thaiv xeb zoo heev. Cov txheej txheem electropolishing ua rau qhov chaw nplua nuj nrog chromium, tsim cov txheej tuab dua, ruaj khov dua uas tiv taus cov pitting thiab tawm tsam los ntawm cov tshuaj lom neeg corrosive.
·BA tubing muaj kev tiv thaiv xeb zoo, los ntawm kev khaws cia cov khoom sib xyaw ua ke, tab sis nws tsis muaj txheej tiv thaiv zoo dua ntawm EP nto.
·Cov yeeb nkab BA pheej yig dua. Nws cov txheej txheem tsim khoom yooj yim dua, nrog rau lub voj voog luv dua, ua rau nws pheej yig dua 30% -50% piv rau cov yeeb nkab EP.
·EP tubing yog ib yam khoom zoo tshaj plaws vim yog cov kauj ruam ua electrochemical ntxiv.
·Kev Lag Luam Semiconductor: Rau cov pa roj uas xav tau kev tswj hwm qhov tsis huv tag nrho ≤ 1.0 × 10⁻⁶, SS316L-EP yog qhov yuav tsum tau ua. Rau cov pa roj inert lossis tsis tseem ceeb, BA raj txaus.
·Tshuaj & Biotech: EP yog qhov zoo dua rau kev hloov cov kua dej huv thiab cov bioreactors kom tiv thaiv kev ua qias tuaj thiab xyuas kom huv.
·Khoom Noj & Dej Haus: Cov raj BA siv dav rau cov kab hloov mis nyuj, brewing, thiab dej haus, muab qhov sib npaug zoo ntawm kev tu cev, kev tiv thaiv corrosion, thiab tus nqi.
Hauv paus ntsiab lus, EP tubing yog qhov kev xaiv zoo tshaj plaws rau qhov xav tau tshaj plaws ultra-high purity, sterility, thiab corrosion resistance. BA tubing yog ib qho kev daws teeb meem zoo, pheej yig rau cov ntawv thov purity siab qhov twg qhov qis tshaj plaws Ra thiab qhov siab tshaj plaws corrosion tsis tseem ceeb.
