Isikhwama Sokupheka Se-Zipper Foil Setha nge-Oxygen Adsorbent

isikhwama se-retort yisikhwama sefilimu esiyinhlanganisela sepulasitiki esingaphathwa ngokushisa, esinobuhle bazo zombili iziqukathi ezifakwe ethini kanye nezikhwama zepulasitiki ezimelana namanzi abilayo.
Ukudla kungashiywa kuphelele esikhwameni, kufakwe inzalo futhi kufudunyezwe ezingeni lokushisa eliphezulu (imvamisa ku-120 ~ 135°C), futhi kukhishwe ukuze kudliwe. Ifakazelwe isikhathi esingaphezu kweminyaka eyishumi, iyisitsha esifanelekile sokuthengisa. Ilungele ukupakishwa kwemikhiqizo yenyama nesoya, ilula, ihlanzekile futhi iyasebenza, futhi ingagcina ukunambitheka kwasekuqaleni kokudla, okuthandwa ngabathengi.
Ngawo-1960, i-United States yasungula ifilimu eyinhlanganisela ye-aluminium-plastic ukuze ixazulule ukupakishwa kokudla kwe-aerospace. Isetshenziselwa ukupakisha ukudla kwenyama, futhi ingagcinwa ekamelweni lokushisa ngokusebenzisa izinga lokushisa eliphezulu kanye nokuvala inzalo yokucindezela okukhulu, nokuphila kweshalofu okungaphezu konyaka ongu-1. Indima yefilimu eyinhlanganisela ye-aluminium-plastic ifana neyekani, elithambile futhi elilula, ngakho liqanjwe ngokuthi ikani elithambile. Njengamanje, imikhiqizo yenyama eneshalofu ende igcinwa ekamelweni lokushisa, njengokusebenzisa iziqukathi zokupakisha kanzima, noma ukusebenzisa amathini e-tinplate namabhodlela engilazi; uma usebenzisa ukupakisha okuguquguqukayo, cishe bonke basebenzisa amafilimu ayinhlanganisela ye-aluminium-plastic.

Inqubo yokukhiqiza yesikhwama sokubuyisela esikwazi ukumelana nokushisa okuphezulu Njengamanje, izikhwama eziningi ze-retort emhlabeni zenziwa ngendlela yokuhlanganisa okomile, futhi ezimbalwa zingabuye zenziwe ngendlela yokuhlanganisa engancibiliki noma indlela yokuhlanganisa i-co-extrusion. Izinga lokuhlanganisa okomile liphakeme kunalelo lokuhlanganisa okungancibiliki, futhi ukuhlelwa nokuhlanganiswa kwezinto kunengqondo futhi kubanzi kunokuhlanganiswa kwe-co-extrusion, futhi kunokwethenjelwa kakhulu ukusebenzisa.

Ukuze kuhlangatshezwane nezidingo zokusebenza zesikhwama se-retort, ungqimba lwangaphandle lwesakhiwo lwenziwe ngefilimu ye-polyester enamandla amakhulu, ungqimba oluphakathi lwenziwe nge-light-shielding, i-aluminium foil eqinile emoyeni, futhi ungqimba lwangaphakathi lwenziwe ifilimu ye-polypropylene. Kunezakhiwo ezinezendlalelo ezintathu: PET/AL/CPP, PPET/PA/CPP;Isakhiwo esinezendlalelo ezine yi-PET/AL/PA/CPP.
