Rhoqo ngonyaka ngexesha lomnyhadala wokuthenga we-"Double 11", amakhulu ezigidi zabathengi baseTshayina baya kuqalisa "ukuthenga, ukuthenga, ukuthenga" usetyenziso lwe-spree. Ngokwedatha yokubeka iliso evela kwi-State Post Bureau, iinkampani zeposi kwilizwe lonke ziphethe iipasile ezizibhiliyoni ezi-4.272 ngexesha le-Double Eleven ngo-2022, kunye ne-avareji yomthamo wokusetyenzwa kwemihla ngemihla ubuphindwe ka-1.3 kumthamo weshishini lemihla ngemihla.
Kwinkqubo yolungiselelo oluntsonkothileyo kunye nenkqubo yothutho, ungaqinisekisa njani ukuba iimveliso zokutya zisiwa kubathengi zigqibelele kwaye zintsha njengangaphambili? Ukongeza ekusebenzeni ngokwaneleyo kuthutho kunye nokusasazwa, ikwafuna inkxaso yetekhnoloji efana nokhuseleko lwamakhonkco abandayo, itekhnoloji yokuvala inzala, kunye nokupakishwa kwevacuum. Phakathi kwazo, izixhobo zefilimu ezisebenzayo kwipakethe ye-vacuum ziyimfuneko.
Iingxowa zokupakisha ze-vacuum zinokuvala ngokufanelekileyo ioksijini, ikharbon diokside, kunye neebhaktheriya, zitshixe ubutsha, zigcine incasa, kwaye zandise ubomi beshelufu yokutya, kwaye zisetyenziswa ngokubanzi kushishino lokutya. Ukongeza, iingxowa zokupakisha ze-vacuum zinokusetyenziswa njengokhuseleko olusisiseko kwizihlangu, iimpahla, kunye neengxowa zokwahlula umoya ukuthintela ukufuma, ukungunda kunye nemikrwelo. Njengefilimu ekhuselayo yeemveliso zombane ezifana neekhamera kunye neelensi, inokuthintela ukufuma kunye nothuli.
Ivela phi imfihlelo yalo msebenzi wokupakisha wevacuum onamandla? Thatha isithintelo esiphezulu se-nayiloni ye-nayiloni edityanisiweyo yefilimu njengomzekelo. Izinto ezisisiseko ezisetyenzisiweyo zizinto eziphezulu zefilimu ze-polyamide.
Njengomboneleli ophambili wehlabathi we-polyamide yomgangatho ophezulu wokusebenza kwefilimu, i-polyamide esebenza ngokuphezulu izilayi ezi-6 eziphuhliswe ngokuzimeleyo kwaye ziveliswa yiSinolong zibonelela ngesisombululo sokutshixwa okutsha komzimba kokupakishwa kokutya kwicala lezinto ezibonakalayo. Ngokwandiswa kwe-bidirectional kunye ne-multi-layer Icutshungulwa kwifilimu ye-nylon 6 ngokusebenzisa iindlela ezahlukeneyo zokucubungula ezifana ne-extrusion, ephucula kakhulu iipropati zesithintelo se-oksijini kunye nexesha lokugcinwa kokutsha kwepakethe, kwaye inceda ngokubanzi ukuphucula ukhuseleko lwezothutho ezicacileyo. Ineengenelo ezininzi:
Okokuqala, umqobo ophezulu kunye nokutshixa ukutsha okusebenzayo
Ifilimu yeNyiloni ye-6 eyenziwe ngezinto eziphathekayo ze-polyamide kunye nezinye izinto ezisisiseko ngokusebenzisa inkqubo ye-multi-layer co-extrusion inokunika umdlalo ogcweleyo kwiipropathi eziphezulu zomqobo wezinto ze-polyamide kunye nokufezekisa iziphumo eziphezulu zokuthintela i-oksijeni, i-carbon dioxide, ibhaktheriya, njl. isetyenziswe kwipakethe ye-vacuum bag, isiphumo sokutshixa ukutsha sigqitha lee kwizinto eziqhelekileyo.
Okwesibini, ukusebenza okuphezulu kunye nemisebenzi emininzi
Izixhobo zePoliamide zineempawu ezibalaseleyo zoomatshini kwaye zinokonyusa kakhulu ukuxhathisa kokukrazula kunye nokumelana nokugqobhozwa kweefilimu zenayiloni. Zingasetyenziselwa ukupakishwa kwevacuum, ukupakishwa kwe-aseptic, ukupakishwa kwe-inflatable, njl.
Okwesithathu, ibakala lokutya lithembeke ngakumbi
Iveliswe ngokuhambelana nemigangatho yamazwe ngamazwe, zonke iiparamitha zemveliso zilawulwa ngokungqongqo kwaye zithobela ukutya kwamazwe ngamazwe, iziyobisi, imigangatho yeekhemikhali kunye neemfuno zokulawula ezifana ne-ROHS, i-FDA, kunye ne-REACH. Izixhobo eziluhlaza nezihambelana nokusingqongileyo zikhusela ukhuseleko lokutya ngcono.
Iinkalo zeSicelo seSinolong seFilimu yeBanga lePolyamide
Ngokusebenzisa ubuchwepheshe obutsha, iSinolong ukuza kuthi ga ngoku iphuhlise uthotho lwemathiriyeli yepolyamide eneempawu ezigqwesileyo ezibanzi, iqhubeka nokuxhasa ukuphuculwa kokusetyenziswa, kwaye ngokuqhubekayo ibonelela ngomgangatho ophezulu, ukusebenza okuphezulu kwezixhobo zokusebenza.
