Isikhwama Sokupheka Se-Zipper Foil Esine-Oxygen Adsorbent

Isikhwama sokuphendula siyisikhwama sepulasitiki esihlanganisiwe esingaphathwa ngokushisa, esinezinzuzo zombili zezitsha ezisemathinini kanye nezikhwama zepulasitiki ezimelana namanzi abilayo.
Ukudla kungashiywa kuphelele esikhwameni, kuhlanzwe futhi kufudunyezwe ekushiseni okuphezulu (ngokuvamile ku-120 ~ 135°C), bese kuyiswa ngaphandle ukuyokudla. Njengoba sekuyiminyaka engaphezu kweyishumi, kuyisitsha sokupakisha esifanelekile sokuthengisa. Kufanelekile ukupakishwa kwemikhiqizo yenyama nesoya, kulula, kuhlanzekile futhi kuyasebenza, futhi kungagcina ukunambitheka kokudla kwasekuqaleni, okuthandwa ngabathengi.
Ngawo-1960, i-United States yasungula ifilimu ehlanganisiwe ye-aluminium-plastic ukuze ixazulule ukupakishwa kokudla kwezindiza. Isetshenziselwa ukupakisha ukudla kwenyama, futhi ingagcinwa ekushiseni kwegumbi ngokushisa okuphezulu kanye nokuhlanza okunamandla aphezulu, kanye nokuphila kweshalofu okungaphezu konyaka owodwa. Indima yefilimu ehlanganisiwe ye-aluminium-plastic ifana neyethini, elithambile futhi elilula, ngakho-ke libizwa ngokuthi ithini elithambile. Njengamanje, imikhiqizo yenyama enempilo ende yeshalofu igcinwa ekushiseni kwegumbi, njengokusebenzisa izitsha zokupakisha eziqinile, noma ukusebenzisa amathini e-tinplate namabhodlela engilazi; uma usebenzisa ukupakishwa okuguquguqukayo, cishe wonke asebenzisa amafilimu enhlanganisela ye-aluminium-plastic.

Inqubo yokukhiqiza isikhwama sokulungisa esimelana nokushisa okuphezulu Njengamanje, iningi lezikhwama zokulungisa emhlabeni zikhiqizwa ngendlela yokuhlanganisa okomile, kanti ezimbalwa zingakhiqizwa nangendlela yokuhlanganisa okungenaso isinyibilikisi noma indlela yokuhlanganisa okuhlanganisayo. Ikhwalithi yokuhlanganisa okomile iphakeme kuneyokuhlanganisa okungenaso isinyibilikisi, futhi ukuhlelwa nokuhlanganiswa kwezinto kunengqondo futhi kubanzi kune-co-extrusion compounding, futhi kuthembekile kakhulu ukuyisebenzisa.

Ukuze kuhlangatshezwane nezidingo zokusebenza zesikhwama sokuphendula, ungqimba lwangaphandle lwesakhiwo lwenziwe ngefilimu ye-polyester enamandla aphezulu, ungqimba oluphakathi lwenziwe nge-foil ye-aluminium evikela ukukhanya, engangenisi umoya, kanti ungqimba lwangaphakathi lwenziwe ngefilimu ye-polypropylene. Kunezakhiwo ezinezingqimba ezintathu: i-PET/AL/CPP, i-PPET/PA/CPP;Isakhiwo esinezingqimba ezine yi-PET/AL/PA/CPP.
