Laser txiav cov tsis raug rau S3555j2Wp: kev kho kom tseem ceeb
Thaum Laser TxiavS3555j2wp huab cua dav hlau, parameter optimization yog qhov tseem ceeb kom raug txiav cov khoom zoo thiab cov pa-kub-cuam tshuam. Ntawm no yog qhov kev hloov kho thiab kev saib xyuas zoo heev:
1. HWJ HUAM & CEEV CEEV
| Tuab (mm) | Laser Fais (W) | Txiav ceev (m / min) | Pab roj | Siab (Bar) |
|---|---|---|---|---|
| 1–3 | 1000–1500 | 4–6 | N₂ lossis o₂ | 8–12 (O₂), 12–15 (N₂) |
| 4–6 | 1500–2500 | 2–4 | O₂ (rau kev txiav kom huv) | 10–14 |
| 6–12 | 2500–4000 | 1–2.5 | O₂ | 12–16 |
| 12–20 | 4000–6000 | 0.5–1.5 | O₂ + N₂ Mix | 14–18 |
Sau ntawv:
O₂tsim cov vaj huv huv tab sis nce tob (0.2-0.5mm). Siv rau cov txheej txheem kev yuav tsum tau siv npaj ua ntej.
N₂txo cov oxidation tab sis yuav tsum muaj zog ntau dua. Qhov zoo tagnrho rau kev ua kom zoo nkauj tiav.
2. Haz tswj rau kev ua yeeb yam
Tom qab txiav kev sib tsoo: Tshem tawm0.1-0.3mmlos ntawm kev txiav sawv kom rov ua kom muaj peev xwm patina-ua kom muaj peev xwm.
Ua kom sov tawm: Khaws tsawg dua lossis sib npaug20 KJ / CMTxhawm rau kom tsis txhob muaj kev phom sij cr / cu nyob rau hauv haz (tseem ceeb rau corrosion tsis kam).
3. Nozzle & Tsom Foos Kho
Nozzle Inchet: 1.2-2.0mm (tuab cov ntaub ntawv yuav tsum tau loj dua nozzles).
Focal txoj hauj lwm:
1/3 rau hauv cov khoom(piv txwv li, {{+1 hli tsom rau 6mm phaj) kom txo qis cov tsav.
4. Tom qab ua rau corrosion tsis kam
Kev ua tshoob: Siv tej hub tawm tsam (SIC) kom tsis txhob muaj hlau kom tsis huv.
Lub caij nplooj zeeg PATINATORATION:
Txau edges nrog5% Cusoaus Tshuajtxhawm rau ua kom muaj xeb tiv thaiv xeb.
Rau cov ntawv thov ntug hiav txwv, thovZinc-nplua nuj Primer(50μm) ntawm kev txiav npoo.
5. Kev siv tau
Iso 9013 chav kawm 2kev ua siab ntev: Khij Kerf Dav (tsawg dua lossis sib npaug rau 0.2 hli rau<10mm thickness).
Kuaj kuaj microhardness microhardness: Haz yuav tsum tsawg dua los yog sib npaug rau 350 hv10 (tiv thaiv brittleness).
