Cov txheej txheem ntim khoom noj uas muaj xws li cua sov sealing, tuag-txiav thiab folding. 6μm yog nyias thiab yooj yim rau cua sov sealing offset thiab over-melting puas thaum tshav kub sealing. Yuav daws cov teeb meem li cas?

1. Lub hauv paus rau phau ntawv: Daim ntawv thov tus nqi ntawm 6μm Aluminium Ntawv Nyiaj hauv cov khoom ntim khoom noj thiab cov txheej txheem kub-Seal Cov ntsiab lus mob

6μm aluminium foil rau ntim khoom noj tau dhau los ua qhov kev xaiv tseem ceeb rau cov khoom noj me me (E.G., 10-50g qov, 20ml seasoning sauce) thiab ntim khoom pov tseg (E.G., instant kas fes hnab) vim nws qhov zoo ntawm “lub teeb yuag (Qhov ntom ntom 16.2g / m², 7.7% qis dua 6.5μm), Tus nqi qis (unit cheeb tsam nqi 0.8-0.9 RMB/m²), thiab zoo heev nyias-formability”. Tshuav, nws txoj kev lag luam sib koom hauv cov khoom ntim khoom noj aluminium foil mus txog 42% hauv 2024 (rau Tuam Tshoj Aluminium Ntawv Nyiaj Ntim Kev Lag Luam Ntawv Dawb).

Txawm li cas los, tus “nyias-hom yam ntxwv” ntawm 6μm aluminium ntawv ci yooj yim ua rau Thaum tshav kub kub-seal teeb meem ntawm 6μm txhuas ntawv ci hauv ntim khoom noj thaum tshav kub-sealing txheej txheem, manifested nyob rau hauv ob core defects: ① Thaum tshav kub kub-seal misalignment (foob ​​ntug misalignment ≥0.5mm, tshaj qhov “foob ​​ntug sib txawv ≤0.3mm” kev xav tau hauv GB / T 2790-2021 Txoj Kev Xeem rau 180 ° Peel Strength of Adhesives), ua rau tsis txaus foob dav thiab a 30%-50% nce nyob rau hauv oxygen kis tus nqi; ② Kev puas tsuaj ntau dhau (pinholes, kub kub, los yog substrate rupture nyob rau hauv lub tshav kub-sealed cheeb tsam, nrog rau kev puas tsuaj ntawm 8%-12%), ncaj qha ua rau cov zaub mov xau, lwj, thiab ib tug ntse nce nyob rau hauv ntau lawm kab scrap tus nqi.

Raws li kev txheeb cais los ntawm lub lag luam ntim khoom, txhua xyoo poob los ntawm Thaum tshav kub kub-seal teeb meem ntawm 6μm txhuas ntawv ci hauv ntim khoom noj account rau kwv yees li 15% ntawm cov nqi tsim khoom. Muab qhov no, Kev tshuaj xyuas qhov ua rau ntawm qhov teeb meem thiab kev tawm tswv yim kev daws teeb meem yog qhov tseem ceeb rau kev txhawb nqa daim ntawv thov loj ntawm 6μm txhuas ntawv ci hauv cov khoom ntim khoom noj.

2. Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Cov Teeb Meem Thaum Tshav Kub Kub Seal ntawm 6μm Aluminium Ntawv Nyiaj hauv Cov Khoom Noj

Hauv paus, Thaum tshav kub kub-seal teeb meem ntawm 6μm txhuas ntawv ci hauv ntim khoom noj qia los ntawm “mismatch ntawm cov khoom vaj tse thiab cov txheej txheem tsis”. Lub hauv paus ua rau tuaj yeem disassembled los ntawm peb qhov ntev: khoom, cuab tam, thiab txheej txheem:

(1) Khoom Khoom: Lub cev yam ntxwv ntawm 6μm Aluminium Foil Amplify txheej txheem rhiab heev

1. Fast kub conduction thiab tsis zoo tshav kub tsis kam: Lub thermal conductivity ntawm 6μm txhuas ntawv ci nce mus txog 235W /(kil k · k) (raws li 6.5μm), tab sis vim nws nyias thickness, nws lub peev xwm kub tsuas yog 92% ua 6,5m. Thaum tshav kub kub-sealing, Thaum tshav kub kub nkag mus rau aluminium ntawv ci txheej sai sai, txo lub sij hawm hloov mus rau lub tshav kub-seal nplaum txheej los ntawm 15%. Yog hais tias qhov kub thiab txias tswj yog imprecise, hauv zos over-melting ntawm cov nplaum txheej yuav tshwm sim. Ntxiv rau, lub tshav kub tsis kam pib ntawm 6μm txhuas ntawv ci (160℃, dhau qhov uas intergranular softening yooj yim tshwm sim) qis dua li ntawm 6.5μm (170℃); me ntsis nce nyob rau hauv lub tshav kub-seal kub yuav ua rau substrate puas, exacerbating qhov teeb meem tshav kub-seal.
