Vacuum packaging ndeyekubvisa mhepo mubhegi rekurongedza uye kuisa chisimbiso zvinhu kuti zvizadzise chinangwa chekuchengetedza kutsva uye kuchengetedza kwenguva refu kwezvinhu zvakaputirwa, izvo zviri nyore kutakura uye kuchengetedza.Vacuum yekurongedza midziyo yemuchina wekuti mushure mekuisa chigadzirwa mumudziyo wekurongedza, uchisveta mweya mukati memudziyo, uchisvika payakatemerwa vacuum degree (kazhinji kutenderera 2000 ~ 2500Pa) uye kupedzisa kuiswa chisimbiso.Inogona zvakare kuzadzwa ne nitrogen kana mamwe magasi akasanganiswa, uye wobva wapedzisa nzira yekuisa chisimbiso.
Kubva kuma1940, tekinoroji yekurongedza yevacuum yakaonekwa uye yakashandiswa.Kusvika pakati-kusvika-pakupedzisira makore makumi mashanu, iyo vacuum yekurongedza munda zvishoma nezvishoma yakatanga kushandisa polyethylene nemamwe mafirimu epurasitiki kurongedza.Mukutanga 1980s, nekukurumidza kukura kweindastiri yekutengesa uye zvishoma nezvishoma kusimudzirwa kwekurongedza kudiki, tekinoroji yakashandiswa uye yakagadziridzwa.Vacuum packaging inokodzera mabhegi epurasitiki akasiyana-siyana efirimu kana aluminium foil composite film bags, zvakadai sepolyester / polyethylene, naironi / polyethylene, polypropylene / polyethylene, polyester / aluminium foil / polyethylene, nylon / aluminium foil / polyethylene, etc.Nekuenderera mberi nekuvandudzika kwekuziva kwevanhu, kushandiswa kwevacuum yekurongedza muchina kwakwezva kutarisisa kwakawanda kubva kumaindasitiri akadai sechikafu, machira, uye zvemagetsi.
Nheyo uye kupatsanurwa kwevacuum yekurongedza midziyo
Chimiro chevacuum yekurongedza midziyo yakasiyana, uye nzira yekuisa nayo yakasiyana.Kazhinji zvinoenderana neakasiyana ekurongedza nzira, inogona kukamurwa kuita mechanical extrusion type, intubation type, chamber type, etc.;maererano nenzira iyo zvinhu zvakaputirwa zvinopinda mukamuri, inogona kukamurwa kuita imwe kamuri, kaviri kamuri, thermoforming mhando, conveyor bhandi rudzi, uye rotary vacuum chamber.Zvinoenderana nerudzi rwekufamba, inogona kukamurwa kuita inopindirana uye inoenderera;zvinoenderana nehukama pakati pechigadzirwa chakaputirwa nemudziyo wekurongedza, inogona kukamurwa kuita vacuum ganda kurongedza uye vacuum inflatable packaging.
Nekuenderera mberi kwekuvandudzwa kwesainzi uye tekinoroji uye nekuenderera mberi kwekuvandudzwa kwemararamiro evanhu, kushandiswa kwevacuum yekurongedza tekinoroji kuchawedzera kuwedzera, uye siyana, chimiro, kuita, uye kunaka kwemidziyo yekurongedza yevacuum ichachinja nekuvandudza.Muindasitiri yemachira uye yemaoko, vacuum packaging inogona kunyatso kudzikisa huwandu hwezvigadzirwa uye kufambisa kurongedza uye kutakura;muindasitiri yezvekudya, vacuum packaging uye sterilization tekinoroji inogona kunyatso kuvharidzira kukura kwebhakitiriya, kunonoka kuparara kwechikafu, uye kuwedzera sherufu yehupenyu hwekudya;mune zvemagetsi, Muindasitiri yehardware, vacuum-yakazara hardware accessories inogona kutsaura okisijeni, kuitira kuti zvishongedzo zvirege kuita oxidize uye ngura.
