Yikuphi ukudla okungafakwa esikhwameni se-vacuum?

Ukudla kungaba yini Akunalutho isikhwama?

Ngokuthuthuka okuqhubekayo kwezinga lethu lokuphila, abantu abaphila impilo ehlukahlukene nabo baye baba noshintsho olukhulu, futhi izikhwama zokupakisha ze-vacuumkuyinto ebalulekile empilweni yethu, Iphakethe LokuhlanzaIzikhwama zokuguga ziwubuchwepheshe bokupakisha bokwandiswa komkhiqizo, isikhwama se-vacuum siyisitsha sokupakisha somoya wonke ophuma ovalweni, ukugcina isikhwama sisezingeni eliphezulu lokucindezeleka, umoya uncane kakhulu olingana nomphumela we-oxygen ephansi, ukuze i-microbial ingabi nezimo zokusinda, ukuze kufezwe izithelo ezintsha, kungabikho izifo nokubola okwenzekayo. Nakuba intengo yeyunithi yesikhwama se-vacuum iphakeme kunentengo yesikhwama evamile, kodwa ikhethwa kakhulu kunezinkampani eziningi zokudla.

Yiziphi izici zezikhwama zokupakisha ze-vacuum?

1, isithiyo esiphezulu: ukusetshenziswa kwezinto ezahlukene zepulasitiki ezinezakhiwo zesithiyo esiphezulu ezihlanganisiwe ifilimu, ukufeza umphumela wesithiyo esiphezulu ku-oxygen, amanzi, i-carbon dioxide, iphunga nokunye.

2, ukusebenza okuzinzile: ukumelana namafutha, ukumelana nomswakama, ukubanda okuphansi kwezinga lokushisa, ikhwalithi, ubusha, iphunga, ingasetshenziswa ukupakishwa kwe-vacuum, ukupakishwa okungenamagciwane, ukupakishwa okufuthwayo.

3, amandla aphezulu: ifilimu ehlanganisiwe enqubweni inezici zokwelula, ukwelula kwepulasitiki kungathuthukiswa ngokufanele, kodwa futhi phakathi kwe-nylon, i-polyethylene nezinye izinto zepulasitiki, ngakho-ke inamandla angaphezu kwavamile okupakisha kwepulasitiki, akukho ukuhlukanisa kwento yokuxebuka, ukuthamba, ukusebenza okuhle kakhulu kokuvala ukushisa.

4, akukho ukungcola: akukho binder eyengeziwe, akukho izinkinga zokungcola kwe-solvent ezisele, okuluhlaza okotshani.

Akuzona zonke ukudla ezifanelekela ukupakishwa kwe-vacuum?

Ngenxa yokuthi izithelo ziwukudla okusha, okusaphefumula, izinga eliphezulu lokushoda komoya-mpilo kuzobangela izifo zomzimba, ngakho-ke, ukusetshenziswa kwe-vacuum packing yezithelo kuncane.

Yikuphi ukudla okufanelekela izikhwama zokupakisha ze-vacuum? Ukuthuthwa kokudla okunamafutha ibanga elide, njengemikhiqizo efakwe emanzini, i-ham, inhlanzi eyosiwe, idada laseBeijing, inkukhu ye-steak yaseTexas, njll. emoyeni kanye nokuxhumana nomoya-mpilo ngemva kwesikhathi eside kuzoba lula ukuwohloka ngemva kokudla okunamafutha amaningi kumele kube ukukhetha kwezikhwama zokupakisha ze-vacuum. Ngezikhwama zokupakisha ze-vacuum, imikhiqizo enamafutha ingagcinwa kuze kube yilapho kuvulwa ukunambitheka okusha nombala.

Yiziphi izinhlobo ze izikhwama zokuhlanza?

Okokuqala, ukusetshenziswa kwabakhiqizi bokupakisha abanemiqulu yefilimu ekugcwaliseni umshini wokupakisha okuzenzakalelayo, kanye nokwakheka nokupakisha ezikhwameni ezahlukahlukene;

Okwesibili, kwenziwa ngomshini wokwenza izikhwama owenziwe ngezikhwama ezahlukene bese ugcwalisa okuqukethwe. Ngenxa yobuchwepheshe bokulawula ukwenza izikhwama, izikhwama ezinhle, izinguquko zokwenza izikhwama, uhlobo lwezikhwama, ngakho-ke, ezimweni eziningi, kuqala zenziwa zibe izikhwama.

Izinhlobo eziyinhloko ze izikhwama zokupakisha ze-vacuum yilezi: izikhwama zokuvala ezinezinhlangothi ezintathu (izikhwama zokuvala zesundu ezivaliwe), izikhwama zokuvala zangemuva, isikhwama esigoqekayo (isikhwama sezitho), izikhwama eziqondile njalo njalo.

Ngokuthuthuka kancane kancane kwezindinganiso zokuphila zabantu, kanye nokuthuthuka okuqhubekayo kwekhwalithi yezidingo zokuphila, ukupakisha nge-vacuum ezimpilweni zabantu banamuhla kuye kwaba nesikhundla esibalulekile, kuyinkambu ejwayelekile yokwanda okuqondile kobuchwepheshe bokupakisha, futhi kudlala indima engenakuphikwa.
