Aluminium Ntawv Nyiaj rau Pharmaceutical Blister Packs - In-depth Manufacturing Standards & Kev taw qhia tswv yim
Kev ncaj ncees ntawm tshuaj blister foil underpins khoom kev ruaj ntseg: nws tsis yog "aluminium" - nws yog ib tug multilayer engineered barrier uas nws metallurgy, Nto Chemistry, thiab cov txheej txheem hloov dua siab tshiab yuav tsum muaj qhov kawg-rau-kawg los tiv thaiv apis thoob plaws txee lub neej, xa xov, thiab tus neeg mob siv.
Hauv qab no Kuv nthuav dav ntawm Metallurgy thiab Cov Txheej Txheem Tswj, Kev kho qhov tsis haum thiab cov hauv paus-ua rau cov neeg, Kev Ntsuas Cov Qauv (Nrog kev lees txais cov txheej txheem), Cov ncauj lus kom ntxaws khoom muab cov ntawv txheeb ze, thiab Exco Eco Alo Alum Co., LTD Kev Tshawb Fawb Kev Tshawb Fawb Qhia Txog Kev Ua Haujlwm thiab Cov Ntaub Ntawv.
1. MeTallurgical & Cov Txheej Txheem Txhua Yam
Aluminium Rau Blister Lidding yog xaiv rau kev sib npaug ntawm ductility, Degy Formarity, thiab qhov teeb meem kev cia siab. Cov Khoom Tseem Ceeb Cov Lus:
- Alloy Scienceistry: Residual ntsiab (Fe, Thiab, Cu, Mn) Cuam tshuam cov formability thiab tus pinhole ntxim nyiam. Cov Khoom Noj Raug / Lub Tshuaj Lidding Alloys (E.G., 8011/8021 tej yim tsev neeg) raug xaiv rau cov neeg ruam loj thiab cov neeg ua haujlwm hnyav-tawv.
- Lis qauv & rov siv dua tshiab: Cev khaub ncaws tseem ceeb, cov nplej nplua nplua txo cov thinning hauv zos thaum xuas nrig ntaus. Cov sij hawm txo cov dej txias thiab tswj cov khoom ua yeeb yam homogeneous microstructures.
- Thickness thiab npau taws tswj: Raug lidding foils li ntau 20-50 μm; Txias-Taus (Dee-Kos) foils siv thicker gauges (≥ 45 μm). Nruj thickness kam rau siab (± 0.5-2 μm nyob ntawm spec) tiv thaiv kev ntxhov siab hauv zos.
Tswv yim tsim tswv tsev: Cam khwb quav plaub hau huv siyliness → Homogenous kub-dov → staged txias kev txo nrog intermediate aneals (Tshuaj Taws Xob) → precision slitting hauv GMP huv chav.
2. Txheej txheem tsis & Raug ntau li
