Cov txheej txheem ntau lawm ntawm cov hnab nqus kas vim cov ntaub ntawv sib txawv, siv thiab kev ua tau zoo, uas yog cov txheej txheem tsim khoom thiab ntim cov txheej txheem. Cov hauv qab no yog qhov sib txawv ntawm cov txheej txheem ntau lawm ntawm ntau hom nqus hnab:
1. Cov khoom siv xaiv sib txawv
Cov khoom siv ntawm lub tshuab nqus tsev txiav txim siab nws ua tau zoo. Cov Khoom Siv Uas Muaj:
PA + PE (nylon + polyethylene): zoo hloov, muaj zog sib cav tiv, feem ntau siv hauv cov khoom noj ntim khoom.
Tsiaj + PE: High Transparency, kev kub siab kuj, tuaj yeem siv rau cov zaub mov khov lossis cov zaub mov sov.
Aluminium Ntawv ci + PE: Kev thaiv cov ntaub ntawv pov thawj, lub teeb thiab dej noo thiab cov khoom pov thawj noo noo, haum rau cov khoom noj pom zoo xws li tshuaj yej thiab kas fes.
Evoh co-extruded zaj duab xis: Lub siab tawv teeb meem, haum rau kev ntim cov nqaij uas muaj cov nqaij ua haujlwm tshiab, cov zaub mov siav, thiab lwm yam.
2. Cov txheej txheem sib txawv ntau lawm
Kev tsim cov tshuab nqus tsev feem ntau cuam tshuam nrog cov txheej txheem hauv qab no:
(1) tshuab moulding txheej
Siv tau rau co-extruded zaj duab xis lub tshuab nqus tsev xws li PA / PE thiab EVOH.
Multi-txheej yas cov ntaub ntawv yog co-extruded los ntawm tshuab moulding khoom los xyuas kom muaj cov khoom siab siab.
(2) Cov txheej txheem casting (Nrum)
Muaj feem xyuam rau lub hnab nqus hnab ua cov khoom siv xws li cov tsiaj / PE.
Cov yas yog melted thiab extruded los ntawm lub tshuab casting, thiab tom qab ntawd tsim los ntawm cov menyuam txias kom txhim kho pob tshab thiab cov tiaj.
(3) Lamination Qhuav
Siv tau rau ntau txheej txheej sib xyaw ua ke nqus dej xws li cov tsiaj / al / PE.
Los ntawm kev thov cov kua nplaum, cov khoom sib txawv tau sib xyaw ua ke los ua cov txheej txheem siab, ntau ntau lub nqus plua plav ntim cov hnab ntim khoom.
(4) cov kuab-lamination
Cov txheej txheem phooj ywg zoo ib puag ncig, tsis txhob muaj cov kev sib tw ntawm cov khoom seem, haum rau cov khoom noj-qib nqus hnab ntau lawm.
Los ntawm cov tshuab hnyav-Lamination-dawb, txhua txheej ntawm cov khoom siv tau kub-nias thiab sib khi kom ntseeg tau tias lub hnab ntim khoom khov.
3. Cov khoom ntim sib txawv
Cov txheej txheem tshav kub kub-sealing ntug: Kev siv kub siab yog siv los xyuas kom meej tias lub foob yog qhov yooj yim thiab tsis yooj yim rau xau.
Peb sab-sab-Foob: Siv rau cov zaub mov ntim xws li nqaij thiab nqaij ntses.
Cov Hnab Sawv ntsug: Siv rau cov zaub mov ua kua lossis khoom noj, tuaj yeem siv nrog lub zipper foob.
Aluminium Ntawv Nyiaj Nqus Plua Plav Hnab Ntim Hnab: Kev Siv Hluav Taws Kub yog siv los xyuas kom meej tias cov ntsiab lus tsis cuam tshuam los ntawm lub teeb thiab oxygen.
Lub kauj vab ntau lawm ntawm cov hnab nqus tsev txawv nyob ntawm cov khoom, lub hom phiaj, thiab kev ua tau zoo. Cov kev sib txawv yog qhov kev xaiv ntawm Co-Extrusion thiab Composite cov txheej txheem, nrog rau cov ntim ntim kawg. Ntau hom nqus plua plav yog tsim nyog rau ntau yam kev lag luam xws li cov khoom noj, cov khoom siv hluav taws xob, thiab txhua yam muaj cov teeb meem kev kub ntxhov, noo noo tsis kam, thiab pob tshab.
