Common Barrier Membrane Material Hom
Qhov kev xaiv ntawm cov khoom thaiv membrane ncaj qha cuam tshuam rau nws qhov kev ua tau zoo. Tam sim no, cov ntaub ntawv tseem ceeb ntawm cov khoom siv hauv kev lag luam muaj xws li polyethylene (PE), polypropylene (PP), polyester (PET), thiab polyamide (PA). Txhua yam khoom muaj nws tus yam ntxwv: PE yog mos thiab pheej yig, PP muaj qhov zoo siab -kub tsis kam, PET muaj zog txhua yam, thaum PA ua haujlwm zoo hauv kev thaiv cov pa roj.
Khoom Siv Khoom Sib Piv Kev Ntsuas
Cov khoom siv yeeb yaj kiab sib txawv muaj qhov sib txawv tseem ceeb hauv cov yam ntxwv ua haujlwm tseem ceeb:
Barrier Performance: PA muab qhov zoo tshaj plaws oxygen barrier kev ua tau zoo, thaum PE yog superior hauv dej vapor barrier kev ua tau zoo.
Mechanical Properties: PET muaj lub zog tensile siab tshaj plaws, thaum PE muaj qhov zoo tshaj plaws elongation.
Kub Ua Haujlwm: PP tuaj yeem tiv taus qhov kub txog li 120 degree, thaum PE feem ntau siv qis dua 90 degree.
Transparency: PET thiab PP muaj cov pob tshab siab, ua raws li PE.
Daim ntawv thov scenarios thiab xaiv cov lus pom zoo
Xaiv cov khoom siv yeeb yaj kiab uas tsim nyog raws li qhov xav tau tiag tiag yog qhov tseem ceeb:
Ntim Cov Khoom Noj: Yuav tsum muaj cov pa oxygen thiab dej vapor barrier kev ua haujlwm; PE / PA cov qauv sib xyaw feem ntau yog siv.
Cov khoom siv hluav taws xob: Yuav tsum muaj lub zog txhua yam thiab kev tiv thaiv electrostatic; PET substrates feem ntau xaiv.
Pharmaceutical Packaging: Yuav tsum muaj kev ua haujlwm zoo ntawm cov pa roj; PA yog qhov kev xaiv zoo tshaj plaws.
Kev Siv Kev Ua Liaj Ua Teb: Ua kom muaj kev ruaj ntseg thiab tus nqi; PE yog ib qho kev xaiv.
