Isingeniso sezinto ezivamile zezikhwama zokupakisha ze-vacuum

Izikhwama zokupakisha ze-vacuumezikhathini zethu zokusebenzisa nsuku zonke kuphezulu kakhulu, imindeni eminingi izosebenzisa Iphakethe Lokuhlanzaizikhwama zokuguga zokupakisha ukudla ukuze kufezwe injongo yokwelula isikhathi sokuphila eshalofini. Izinto zesikhwama se-vacuum zithinta ngqo ukusebenza kwaso kokusha, umbukiso olandelayo we-vacuum sizofunda ngezinto kanye nezici zesikhwama se-vacuum packaging.

Izinto zokupakisha ze-vacuum ezisetshenziswa kakhulu ezingeni lokudla zinezigaba ezilandelayo:

1, i-polyester izikhwama zokuhlanza:

I-Polyester yigama elijwayelekile lama-polymer atholakala nge-polyol kanye ne-polyacid polycondensation. Ibhekisela kakhulu ku-polyethylene terephthalate (PET), isikhwama se-vacuum se-polyester (PET) esingenambala futhi esibonakalayo, esicwebezelayo, sisekelwe ku-polyethylene terephthalate njengezinto zokusetshenziswa, kusetshenziswa indlela yokukhipha ibe yishidi elijiyile, bese kuba ukwelulwa okuqondile okwenziwe ngezinto zesikhwama se-vacuum. Izakhiwo ezinhle kakhulu zemishini, ukuqina okuphezulu, ubulukhuni nokuqina, ukumelana nokubhoboza, ukumelana nokungqubuzana, ukumelana nokushisa okuphezulu nokuphansi, ukumelana namakhemikhali, ukumelana namafutha, ukungabi nomoya kanye nokugcinwa okuhle kwephunga, kungenye yezingxenye ezivame ukusetshenziswa zesikhwama se-vacuum esihlanganisiwe esivimbela ukungena. Ivame ukusetshenziswa ukwenza ungqimba lwangaphandle lwezinto zokupakisha ezipheka ngomusi, ukusebenza kwengcindezi kungcono.

2, isikhwama se-vacuum se-nylon:

Isikhwama se-vacuum se-nylon (PA) siyisikhwama se-vacuum esiqinile kakhulu, sibonakala kahle, futhi sinokukhanya okuhle, sinamandla okubamba, sinamandla okubamba aphezulu, siphinde sibe nokumelana okuhle nokushisa, ukumelana nokubanda, ukumelana namafutha kanye nokumelana nezinyibilikisi eziphilayo, ukumelana nokuklwebheka, ukumelana nokubhoboza kuhle kakhulu, futhi sithambile kakhulu, isithiyo se-oxygen sinhle kakhulu, sifanelekela ukupakishwa kwezimpahla eziqinile, njengokudla okunamafutha, imikhiqizo yenyama, ukudla okuthosiwe, ukudla okugcwele i-vacuum, ukudla okuphekiwe, njll.

Kususelwa ku-nylon Izikhwama Zokuhlanza Umshini kungatholakala ezikhwameni ze-nylon ezihlanganisiwe ezisebenza kahle kakhulu kanye nasezikhwameni ze-vacuum ezihlanganisiwe ezisebenzisa izingqimba eziningi.

Izikhwama ze-nylon ezihlanganisiwe zakhiwe kakhulu yi-PET/PE, i-PVC/PE, i-NY/PVDC, i-PE/PVDC, i-PP/PVDC, umehluko omkhulu phakathi kwe- isikhwama esihlanganisiwe futhi inqubo ngokuvamile iqukethe i-substrate, ingcina yokunamathisela, izinto zokuvimbela, izinto zokuvala ukushisa, ukuphrinta nokuvikela nezinye izingxenye.

Ingxenye eyinhloko yesikhwama se-vacuum esinwetshiwe esinezingqimba eziningi yi-nylon, eyenziwe nge-PA, EVOH kanye ne-PE, PP, TIE kanye nezinye izinhlayiya, kusetshenziswa isakhiwo sokuhlanganiswa esilinganayo noma esingalingani. Njengoba i-PA, EVOH ihlangene, ayithuthukisi nje kuphela ifilimu enezingqimba eziningi ku-oxygen kanye nesithiyo sokunambitha, amandla e-composite peel, ukumelana kwemvelo kanye nesikhathi sokugcina esisha. Njengoba kungekho ukungcola, isithiyo esiphezulu, umsebenzi oqinile, izindleko eziphansi, isilinganiso esincane samandla, amandla aphezulu, isakhiwo esiguquguqukayo njalo njalo, kwenza inqubo yokukhiqiza izinto zokupakisha ukudla iphumelele ekungcoleni.

3, Isikhwama se-vacuum se-PE:

I-Polyethylene (i-polyethylene, i-PE emfushane) iyi-resin ye-thermoplastic ekhiqizwa yi-polymerization ye-ethylene. Icacile iphansi kune-nylon, izwakala iqinile, izwakala ibuthakathaka, inesithiyo segesi esihle kakhulu, isithiyo samafutha kanye nezakhiwo zokugcina iphunga. Ayifanele ukusetshenziswa ekushiseni okuphezulu nasekuqandisini, futhi intengo ishibhile kuneye-nylon. Ngokuvamile isetshenziselwa izinto ezivamile zesikhwama se-vacuum ngaphandle kwezidingo ezikhethekile.

4, isikhwama sokuhlanza i-aluminium foil:

Isikhwama se-vacuum esihlanganisiwe se-aluminium-plastic (i-PET/AL/PE noma i-PET/NY/AL/PE noma i-PET/NY/AL/CPP), ingxenye eyinhloko ye-aluminium foil, engacacile, emhlophe njengesiliva, ene-anti-gloss, enesithiyo esihle, ukuvala ukushisa, ukuvikela ukujika, ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nowoyela, ukugcinwa kwephunga; ayinabo ubuthi futhi ayinambitheki; ubumnene nezinye izici. Ifanele imishini nemishini enembile kakhulu, izinto zokusetshenziswa zamakhemikhali, izinto zokwelapha eziphakathi, ukupakisha okungenamswakama, ukukhanya, i-vacuum. Isakhiwo esingaphezu kwezingqimba ezine, esinomsebenzi omuhle wokuvimbela amanzi nomoya-mpilo. Isikhwama se-vacuum foil se-aluminium sisetshenziswa kabanzi ekudleni, kuma-elekthronikhi, kumakhemikhali nakwezinye izimboni, ngoba i-aluminium foil ngokwayo ibiza kakhulu, ngakho-ke izindleko ze-vacuum zizoba phezulu.

Lokhu okungenhla kuwumbukiso we-vacuum ofingqiwe ku- izikhwama zokupakisha ze-vacuum Izinto ezisetshenziswa kakhulu kanye nezici zesingeniso, ngikholwa ukuthi ngemva kokufunda abangane abaningi ekukhetheni izikhwama zabo zokupakisha umkhiqizo bazoba nokuqonda okujwayelekile ngakho, bafuna ukwazi ulwazi olwengeziwe, wamukelekile ukuxhumana nathi.
