Yuav Ua Li Cas Tshawb Pom Pinhole Defects hauv Aluminium Ntawv Nyiaj
Aluminium foil pinhole kuaj yog ib qho tseem ceeb ntawm cov txheej txheem tswj kev ua tau zoo uas txiav txim siab qhov thaiv kev ncaj ncees ntawm cov ntawv ci siv hauv ntim khoom noj, tshuaj blister foil, aseptic laminates, tsev ntawv ci, thiab cov ntaub ntawv muaj rwb thaiv tsev. Txij li aluminium ntawv ci feem ntau tsuas yog cov hlau thaiv txheej hauv ntau txheej txheej, Txawm tias micro-pinhole tsis xws luag tuaj yeem cuam tshuam cov dej tsis haum, oxidation stability, thiab khoom txee lub neej. Yog li ntawd, tsim kom muaj tseeb, rov ua tau, thiab kev lag luam-tus qauv pinhole nrhiav kom tau txoj hauv kev yog qhov tseem ceeb rau cov tuam txhab nrhiav kev ua haujlwm zoo ib yam.
Vim li cas Pinhole Detection tseem ceeb
Pinhole defects feem ntau tshwm sim thaum dov, annealing, slitting, los yog tuav. Qhov loj me me yuav txawv ntawm qhov pom (>100 μm) mus rau micro-pinhole pawg (<40 μm) uas yuav tsum tau siv txoj kev kho qhov muag lossis hluav taws xob. Cov teeb meem no cuam tshuam ncaj qha:
- Dej vapor kis tus nqi (WVTR)
- Oxygen kis tus nqi (OTR)
- Mechanical zog ntawm cov ntawv ci
- Sterility kev ua tau zoo hauv kev ntim khoom kho mob
- Txee-lub neej ntawm noo noo-rhiab khoom
Txawm High-qib txhuas ntawv ci (6-12 μm) tuaj yeem txhim kho pinholes vim cov khoom siv rho tawm thaum lub sijhawm so kawg. Raws li qhov tshwm sim, Rigorous pinehole tshuaj xyuas yog yuav tsum tau rau cov nqi lag luam zoo thiab cov kab ke high-barrier laminates.
Cov Qauv Kab Pinhole Nrhiav Kom Tau
1. Backlight Option Soj ntsuam
Nov yog qhov feem ntau cov qauv siv rau kev sim ua ib txwm muaj. Ib qho muaj zog thiab lub teeb pom kev zoo illuminates cov ntawv ci los ntawm qab. Pinhole cov ntsiab lus tshwm sim ua lub teeb ci ntsa iab.
Qhov Zoo:
- Kev yoov mov
- Tsis Yog-Phom Sij
- Yooj yim rau kev khiav lag luam
Kev txwv:
- Tsis haum rau ultrafine micro-cinhole nrhiav
- Ua tau raws li cov neeg teb xov tooj
2. Tsis Siv Neeg Optical Tus Kws Tshuaj Ntsuam Xyuas (Lub Koob Yees Duab Scan System)
High-precision optical scanners tau nruab nrog CCD / Cmos koob thaij duab ntxaij cov ntawv ci thiab txheeb xyuas qhov hluav taws xob ua haujlwm raws li pixel.
Cov yam ntxwv tseem ceeb:
- Kuaj pom pinholes li 5-10 μm
- Cov Ntaub Ntawv Digital ntawm Kev Txhim Kho Qhov Loj & suav
- Haum rau cov ntim ntau lawm (reel-rau-reel)
Txoj kev no yog qhov zoo dua rau cov chaw tsim tshuaj ntim tshuaj uas xav tau cov ntaub ntawv pov thawj thiab cov ntaub ntawv pov thawj.
3. Electrolytic conductivity (Ntsuas ntsuas) Txoj kev
Hauv txoj kev no, cov ntawv ci yog muab tso rau hauv ib da dej conductive electrolyte. Thaum lub pinhole tso cai rau hluav taws xob tam sim no dhau los, qhov ntsuas sau npe ib lub txim.
Daim ntawv thov: nyias industrial foils, Capacitor ntawv ci, rwb thaiv tsev foils.
Lub zog:
- Heev rhiab heev rau conductive paths
- Tshawb xyuas micro-tsis xws luag hauv qab qhov kev daws teeb meem kho qhov muag
Tsis muaj zog:
- Yuav ua rau puas tsuaj
- Yuav tsum tau tswj lub chaw kuaj teeb tsa
Lub rooj 1. Standard Requirements for Aluminium Foil Pinhole Testing
| Parameter | Kev lag luam siv Standard | Yam yuav tsum tau muaj | Sau ntawv |
|---|---|---|---|
| Ntawv Nyiaj Thickness | 6- 25 m os | Thinner foil → ntau pinholes | Feem ntau hauv cov khoom noj & tshuaj |
| Lub teeb siv rau Backlight | ≥ 2000-3000 lux | Qhov chaw ruaj khov zoo li qub | Tiv thaiv qhov tsis zoo |

|---|---|---|---|---|
| Backlight Optical | 40- 100 μm | Kev yoov mov, yooj yim, Tus nqi qis | Tsis nco micro-pinholes | Ntim khoom noj, QC niaj hnub |
| CCD/CMOS Lub Koob Yees Duab Scan | 5- 20 m os | High precision, traceable cov ntaub ntawv | Tus nqi peev ntau dua | Pharma ntawv ci, high-barrier laminates |
| Electrolytic conductivity | <5 μm | Ultra-rhiab heev, kuaj pom cov pinholes me tshaj plaws | Kev puas tsuaj, qeeb dua | Industrial foils, Capacitor ntawv ci |
Yuav ua li cas manufacturers txhim kho Pinhole zoo
Yuav kom ua tau raws li nruj pinhole specifications, manufacturers feem ntau siv:
- High-purity aluminium ingots kom txo tau cov kev suav nrog
- Precision dov mills nrog muaj zog deg huv si tswj
- Multi-theem filtration thaum melting thiab casting
- Kev ntim khoom huv chav rau kev kho mob-qib ntawv ci
- Real-time optical soj ntsuam tshuab ntawm txoj kab tiav
Cov kev ntsuas no ncaj qha txo cov neeg kho tshuab puas tsuaj, yob impression marks, thiab particle-induced micro-defects.
