Ukufakwa kwe-vacuum ukukhipha umoya esikhwameni sokupakisha bese uvala izinto zokwakha ukuze kuzuzwe inhloso yokulondoloza ukusha nokugcinwa isikhathi eside kwezinto ezipakishiwe, ezilungele ukuthuthwa nokugcinwa.Imishini yokupakisha i-vacuum ingumshini okuthi ngemva kokufaka umkhiqizo esitsheni sokupakisha, ukhiphe umoya ngaphakathi kwesiqukathi, ufinyelele idigri ye-vacuum enqunywe kusengaphambili (imvamisa cishe ku-2000 ~ 2500Pa) futhi uqedele ukuvala.Ingabuye igcwaliswe nge-nitrogen noma amanye amagesi axubile, bese uqedela inqubo yokuvala.
Kusukela ngawo-1940, ubuchwepheshe bokupakisha be-vacuum buye bavela futhi basetshenziswa.Kuze kube maphakathi nasekupheleni kweminyaka engama-50, inkambu yokufaka i-vacuum kancane kancane yaqala ukusebenzisa i-polyethylene namanye amafilimu epulasitiki ukupakisha.Ekuqaleni kwawo-1980, ngokuthuthuka okusheshayo kwemboni yokudayisa kanye nokukhuthazwa kancane kancane kokupakishwa okuncane, ubuchwepheshe basetshenziswa futhi bathuthukiswa.Ukupakishwa kwe-vacuum kulungele izikhwama zefilimu eziyinhlanganisela yepulasitiki ehlukahlukene noma izikhwama zefilimu eziyinhlanganisela ye-aluminium foil, njenge-polyester/polyethylene, inayiloni/polyethylene, i-polypropylene/polyethylene, i-polyester/i-aluminium foil/i-polyethylene, inayiloni/i-aluminium foil/i-polyethylene, njll.Ngokuthuthuka okuqhubekayo kokuqwashisa kwabantu ngemibono, ukusetshenziswa kwemishini yokupakisha i-vacuum sekudonse ukunakwa okwengeziwe okuvela ezimbonini ezifana nokudla, izindwangu, kanye ne-electronics.
Isimiso nokuhlukaniswa kwemishini yokupakisha ye-vacuum
Isakhiwo semishini yokupakisha i-vacuum sihlukile, futhi indlela yokuhlukanisa nayo ihlukile.Imvamisa ngokwezindlela ezihlukene zokupakisha, ingahlukaniswa ngohlobo lwe-extrusion lwemishini, uhlobo lwe-intubation, uhlobo lwegumbi, njll.;ngokwendlela izinto ezipakishiwe ezingena ngayo ekamelweni, ingahlukaniswa ngekamelo elilodwa, igumbi eliphindwe kabili, uhlobo lwe-thermoforming, uhlobo lwebhande elihambisayo, kanye negumbi le-rotary vacuum.Ngokusho kohlobo lokunyakaza, ingahlukaniswa ibe yisikhashana futhi eqhubekayo;ngokuya ngobudlelwano phakathi komkhiqizo opakishiwe kanye nesitsha sokupakisha, ingahlukaniswa ibe yi-vacuum yesikhumba yokupakisha kanye ne-vacuum inflatable packaging.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nokuthuthuka okuqhubekayo kwamazinga okuphila abantu, ukusetshenziswa kobuchwepheshe bokufaka i-vacuum kuzokwanda kakhulu, futhi ukuhlukahluka, isitayela, ukusebenza, kanye nekhwalithi yemishini yokupakisha ye-vacuum kuzoshintsha futhi kuthuthuke.Embonini yendwangu kanye nemisebenzi yezandla, ukupakishwa kwe-vacuum kunganciphisa ngempumelelo umthamo wemikhiqizo futhi kube lula ukupakishwa nokuhamba;embonini yokudla, ukupakishwa kwe-vacuum kanye nobuchwepheshe bokuvala inzalo kungavimbela ngempumelelo ukukhula kwamagciwane, kubambezele ukubola kokudla, futhi kwandise impilo yeshalofu yokudla;ku-electronics, Embonini ye-hardware, izesekeli ze-hardware ezigcwele i-vacuum zingahlukanisa umoya-mpilo, ukuze izesekeli zingafaki i-oxidize futhi zigqwale.
