Ukubaluleka Kobukhulu Besikhwama Sokupakisha I-Vacuum

Ukufana kobukhulu nobukhulu bomkhiqizo oqediwe kuncike kakhulu ekujikeni nasekufaneni kwefilimu enesendlalelo esisodwa ngaphambi isikhwama sokupakisha se-vacuuminhlanganisela, okungukuthi, ukulawula ikhwalithi yobukhulu befilimu enesendlalelo esisodwa se- Iphakethe LokuhlanzaIsikhwama sokuguga siwukuthola ikhwalithi yobukhulu bomkhiqizo oqediwe ofanelekayo.

Imfuneko.

② isikhwama sokupakisha se-vacuum esivimba ifilimu kanye ifilimu yesikhwama sokupakisha se-vacuum ukujiya kuhlobene eduze (ngokuvamile kuhambisana nokujiya kobudlelwano), ukufana okuhle kwefilimu yesikhwama sokupakisha se-vacuum kungathola isithiyo esifanayo nesizinzile.

③ ukufana kwefilimu yokujiya kwesikhwama sokupakisha se-vacuum kuthinta ngqo izakhiwo zokuthambekela kwefilimu, ukufana kobukhulu befilimu yokupakishwa kwesikhwama sokupakisha se-vacuum kungathola ukunemba okungcono kokuphrinta kanye nekhwalithi ehlanganisiwe.

④ okuhlanganisiwe Ifilimu Yesikhwama Sokuhlanza I-Vacuum ngezinto ezifanayo zangaphakathi, ukujiya kuphakeme kunokuqala kokushisa, izinga lokushisa lokuvala liphezulu, futhi okuphambene nalokho. Okusho ukuthi,ifilimu yesikhwama sokupakisha se-vacuum esihlanganisiwe ngobukhulu obufanayo kungafinyelela ikhwalithi efanayo yokuvala futhi kugweme isimo sokuvala ukushisa okubi endaweni.

Iningi lamakhasimende lithatha idatha yokulethwa ngemitha yesikwele, engalawula ngempumelelo izindleko zokucubungula ifilimu elaminethiwe.

Yiziphi izinzuzo ze- izikhwama zokudla ezihlanzekile?

1. Izici zomkhiqizo zibukeka: azibonakali, zimhlophe njengesiliva, azicwebezeli, zinokushisa okuhle kakhulu, zivala ukushisa, zivikela ukusonta, zimelana nokushisa okuphezulu, zimelana nokushisa okuphansi, zimelana nowoyela, zigcina iphunga; azinabo ubuthi futhi azinambitheki; zithambile nezinye izici.

2. Isakhiwo somkhiqizo: singenziwa ngokwezifiso ngokuya ngezidingo zezinto ezihlanganisiwe ezahlukene kanye nobukhulu bomkhiqizo. Izinga lokushisa lendawo yokugcina izinto ≤38℃, umswakama ≤90%.

3. Imininingwane yomkhiqizo: ukujiya okungu-0.10mm no-0.14mm, ukuvalwa kwezinhlangothi ezintathu, umkhawulo wokuvala ongu-10mm, isikali semininingwane yomkhiqizo singenziwa ngokwezifiso ngokuya ngesidingo samakhasimende.

Izikhwama zokupakisha ze-vacuum yokudla zisebenzisa izinto zokusetshenziswa ezivikela kakhulu ukuqinisekisa ukuphepha kokudla

Izikhwama zokupakisha ukudla ezisebenzisa ugesi Izinzuzo ezivame ukusetshenziswa ezikhwameni zokupakisha ze-aluminium foil.

1, umsebenzi oqinile wokuvimbela umoya, ukulwa ne-oxidation, ukungangeni manzi, umswakama.

2, umsebenzi oqinile womshini, umsebenzi wokulwa nokuqhuma, umsebenzi wokulwa nokubhoboza nokuklebhula.

3, ukumelana nokushisa okuphezulu (121 ℃), ukumelana nokushisa okuphansi (-50 ℃), ukumelana nowoyela, umsebenzi omuhle wephunga.

4, ayinabo ubuthi futhi ayinambitheki, ngokuvumelana nezindinganiso zezempilo zokupakishwa kokudla, kwemithi.

5, umsebenzi omuhle wokuvala ukushisa, ukuguquguquka, umsebenzi wokushisa ophezulu.

Isikhwama sokupakisha ukudla esinomshini wokufaka umoya esifakwe emaphaketheni okufaka umoya ophezulu - izinto zokupakisha ezivame ukusetshenziswa kakhulu njenge-aluminium foil, i-nylon, i-polyester, i-polyvinylidene chloride.

Uhlobo olusha lwezinto zokupakisha ezivikela ukushisa okuphezulu (izinto zokupakisha ezivikela ukushisa okuphezulu ezivame ukusetshenziswa yi-aluminium foil, i-nylon, i-polyester, i-polyvinylidene chloride, njll.). Ngokuthuthuka kwezidingo zokulondolozwa kokudla. Izinto zokupakisha ezintsha zepulasitiki ezivikela ukushisa okuphezulu ziye zasetshenziswa kabanzi emazweni angaphandle, ukusetshenziswa kwepulasitiki enamandla aphezulu okuvikela ukushisa okuphezulu akugcini nje ngokuthuthukisa ukugcinwa kokudla, futhi ekupakisheni inani elifanayo lokudla kunganciphisa inani lepulasitiki. Isikhwama se-vacuum esimelana ne-static ngezidingo zokugcinwa kokuvikela ukushisa okuphezulu kokudla okucutshunguliwe kanye nokupakisha kwe-vacuum, ukupakisha okufuthwayo, njll., ngokuvamile kufanele kusetshenziswe izinto zokupakisha ezinhle kakhulu ezihlanganisiwe, futhi ezintweni zokuhlanganisa eziningi qagela ukuthi kumele kube nezingqimba ezingaphezu kweyodwa zezinto zokuvikela ukushisa okuphezulu. Isibonelo, izinto zokupakisha ezintsha ezivikela ukushisa okuphezulu eziguqulwe nge-nano-modified polyamide, i-ethylene vinyl alcohol copolymer, i-polyvinyl alcohol njalo njalo. Izinto zokupakisha zokudla kumele zibe nezinga eliphezulu lokuvikela ukushisa. Izidingo zokudla okunamafutha zinesithiyo esikhulu se-oxygen kanye nesisithiyo samafutha; izidingo zokudla okomile zinesithiyo esikhulu somswakama ukuqinisekisa ukuhamba kahle kokudla okupakishiwe. Izidingo zokudla okunephunga elimnandi zinezinga eliphezulu lephunga; Izidingo zokudla okusha zezithelo nemifino zinomoya-mpilo ophezulu, i-carbon dioxide kanye nokuvuleka komhwamuko wamanzi. Ngaphezu kwalokho, izinto zokupakisha ukudla kufanele futhi zibe namandla aphezulu okudonseka, ukumelana nokudabuka, ukumelana nokushayisana, ukuzinza okuhle kwamakhemikhali, ukungabi nanoma yikuphi ukusabela kwamakhemikhali nokuqukethwe kokudla ukuqinisekisa ukuphepha kokudla; ​​abanye basenokumelana nokushisa okuphezulu ukuhlangabezana nokuhlanza ukudla okushisayo okuphezulu kanye nokugcinwa kwezinga lokushisa eliphansi kanye nezinye izidingo.
