Umhlahlandlela Ophelele Wezinto Zokufaka Izikhwama Zokuhlanza I-Vacuum kanye Nezicelo Zemishini Yokupakisha Imishini Yokuhlanza I-DJVAC

Ukubuka Konke Kokupakisha I-Vacuum kanye Nezinto Zesikhwama

Imishini yokupakisha nge-vacuum (izinhlobo zegumbi noma zokudonsa) isusa umoya esikhwameni noma ekamelweni lomkhiqizo, bese ivala isikhwama ukuze ivimbele amagesi angaphandle. Lokhu kwandisa kakhulu isikhathi sokuphila ngokunciphisa ukuvezwa komoya-mpilo nokuvimbela amagciwane angcolisayo..Ukuze kufezwe lokhu, izikhwama zokuhlanza kumele zihlanganise izakhiwo eziqinile zokuvimbela nokuqina kwemishini kanye nokuvalwa kokushisa okuthembekile.Izikhwama ze-vacuum ezivamile ziyizingqimba eziningi zepulasitiki, ngayinye ikhethelwe izici ezifana nesithiyo se-oxygen/umswakama, ukumelana nokushisa, ukucaca kanye nokuqina kokubhoboza..

Izikhwama Zokushaja Ezine-Nylon/PE (PA/PE)

•Ukwakheka kanye nezakhiwo:Izikhwama ze-PA/PE ziqukethe ungqimba lwangaphandle lwe-nylon (polyamide) olubekwe ungqimba lwangaphakathi lwe-polyethylene.Ingqimba ye-nylon inikeza ukubhoboza okuphezulu kanye nokumelana nokuhuzuka kanye nesithiyo esikhulu se-oxygen/aroma, kuyilapho ungqimba lwe-PE luqinisekisa ukuvalwa kokushisa okuqinile ngisho noma kusezingeni lokushisa eliphansi..Uma kuqhathaniswa nefilimu ye-PE ecacile, ama-laminate e-PA/PE anikeza umoya-mpilo ophezulu kakhulu kanye nesithiyo sephunga kanye nokumelana okungcono kakhulu nokubhoboza.Ziphinde zigcine ukuqina kobukhulu ezinqubweni zokuqandisa okujulile kanye nezinqubo zokushisa, futhi zimelana nokushisa okulingene ngesikhathi sokuvala.

•Izicelo:Amaphakethe e-PA/PE asetshenziswa kabanzi enyameni entsha neqandisiwe (inyama yenkomo, ingulube, inkukhu, ukudla kwasolwandle) ngoba inayiloni imelana nemiphetho yamathambo nezingcezu ezibukhali.Lezi zikhwama zigcina umbala wenyama kanye nokunambitheka kuphelele ngesikhathi sokugcina isikhathi eside ebanda. Ziphinde zibe zinhle kakhulu emikhiqizweni kashizi kanye ne-deli, zigcina ukunambitheka kanye nokuthungwa ngokusika ukungena komoya-mpilo. Ifilimu eqinile isebenza ngisho nasenyameni ecutshungulwayo, ama-pâté noma ukudla okulungisiwe. Ama-semi-liquid nama-sauce angafakwa nasezikhwameni ze-PA/PE; ungqimba oluqinile lokuvala luvimbela ukuvuza futhi lugcina amaphunga..Ngamafuphi, izikhwama ze-PA/PE zifanela noma yikuphi ukudla okunemiphetho engajwayelekile noma eqinile (amathambo, ama-chips enyama) okudinga ukuqandiswa isikhathi eside noma ukuqandiswa.

•Ezinye Izindlela Zokusebenzisa:Ngaphandle kokudla, ama-laminate e-PA/PE asetshenziselwa ukupakisha kwezokwelapha kanye nezingxenye zezimboni. Ifilimu enesivikelo esiphezulu futhi eqinile ingahlanzwa futhi ivalwe ngamakhithi ezokwelapha, kuyilapho emaphaketheni e-elekthronikhi ilawula umswakama futhi yengeze amandla emishini..Izendlalelo ezilwa nokungaguquguquki noma ezivimbelayo zingangezwa kumabhodi wesekethe noma kwihadiwe. Ngamafuphi, izikhwama ze-PA/PE ziyifilimu esebenza kahle – isithiyo esiphezulu kanye namandla aphezulu okubhoboza – ziyahambisana neziningi ze-vacuum sealers (igumbi noma yangaphandle), okwenza zibe ukukhetha okuphezulu kokupakisha i-vacuum evamile.

Izikhwama Zokushaja Ezisebenzisa I-Polyester/PE (PET/PE)

•Ukwakheka kanye nezakhiwo:Amaphakethe e-polyester/PE (avame ukubizwa ngokuthi amaphakethe e-PET/PE noma e-PET-LDPE) asebenzisa ungqimba lwangaphandle lwe-PET (polyethylene terephthalate) olune-PE yangaphakathi.I-PET isobala kakhulu, iqinile futhi izinzile ngokwezinga, inokumelana okuvelele kwamakhemikhali nokushisa.Inesithiyo esihle kakhulu se-oxygen kanye namafutha, amandla amahle kakhulu (5–10× amandla okudonsa e-PE) futhi igcina izakhiwo zomzimba ebangeni elibanzi lokushisa..Ngakho-ke izikhwama ze-PET/PE zinikeza ukucaca (izikhwama ezibonayo) kanye nesithiyo esimaphakathi.Ziqinile futhi azinwebeki kakhulu kune-PA/PE, ngakho-ke ukumelana nokubhoboza kuhle kodwa akuphakeme kangako.(Ezintweni ezinamachashaza abukhali kakhulu, ungqimba lwenayiloni lungcono kakhulu.)

•Izicelo:Izikhwama zokuhlanza ze-PET/PE zilungele izinto ezidingaukucaca kanye nokumelana namakhemikhaliZivame ukusetshenziselwa inyama ephekiwe noma ebhemayo kanye nenhlanzi lapho kubonakala khona, isibonelo lapho ikhwalithi yokupakishwa ibalulekile khona. Ukuqina kuzenza zivaleke ngokushisa emishinini ezenzakalelayo.Njengoba i-PET inokuqina okuhle kwezinga lokushisa, izikhwama ze-PET/PE zisebenza kokubili emikhiqizweni efrijini kanye nemikhiqizo ezungezile (isb. ubhontshisi wekhofi ogcwele i-vacuum noma izinongo).Zisetshenziswa futhi njengefilimu ephezulu emigqeni yokupakisha ye-thermoforming vacuum (ene-PA/EVOH/PE forming web).

•Inothi Lobuchwepheshe:Isithiyo esinamandla se-polyester kumagesi sisiza ukugcina iphunga, kodwa i-PET/PE emsulwa ayinayo isithiyo esijulile se-oxygen kanye nokuqina kokubhoboza kwe-PA/PE.Eqinisweni, i-PET/PE ngezinye izikhathi inconywa ezintweni ezithambile noma ezingasindi kakhulu.Isibonelo, amasobho agcwele i-vacuum, impuphu noma ukudla okulula okulula.I-CarePac iphawula ukuthi ungqimba oluqinile lwe-polyester (noma i-nylon) luvimbela ukubhoboka futhi lufanelekela ukuvalwa kwe-vacuum.Empeleni, abaprosesa abaningi bakhetha i-PET/PE yemikhiqizo ehlala isikhathi esiphakathi eshalofini futhi basebenzisa ukuthungwa okuhlanganisiwe (uma besebenzisa imishini yokumunca) ukuze baqinise ukuvalwa..Izikhwama ze-PET/PE ziyahambisana nayo yonke imishini yokupakisha i-vacuum, yize zisebenza kahle kakhulu kumayunithi egumbi (kungenzeka amazinga aphezulu e-vacuum).

Amafilimu Anezingqimba Eziningi Ezinezithiyo Eziphakeme (i-EVOH, i-PVDC, njll.)

•Izikhwama Ezisekelwe ku-EVOH:Ukuze kuhlale isikhathi eside kakhulu eshalofini, ama-laminate anezingqimba eziningi afaka i-resin evimbelayo njenge-EVOH (i-ethylene-vinyl alcohol). Izakhiwo ezijwayelekile yi-PA/EVOH/PE noma i-PE/EVOH/PE. I-EVOH core inikeza izinga eliphansi kakhulu lokudlulisa umoya-mpilo, kuyilapho i-nylon noma i-PET ezungezile inezela amandla okusebenza kanye nokuvaleka..Le nhlanganisela iveza isithiyo esiphezulu kakhulu: Izikhwama ze-EVOH zinciphisa kakhulu ukufuduka kwe-oxidation kanye nomswakama. Abanye ochwephesheumbiko wokuthi uma kuqhathaniswa nezikhwama ze-PA/PE, ama-laminate e-EVOH asiza ekufezeni isikhathi eside sokuhlala efrijini noma eqandisiwe ngokulahlekelwa okuncane komkhiqizo.

•Izakhiwo:Ifilimu ye-EVOH iyabonakala futhi iyaguquguquka, kodwa ezikhwameni ze-vacuum igqitshwe phakathi kwezingqimba ezingacacile.Lezi zikhwama zigcina ubuqotho bokuvala obudingekayo ngokuqandisa, futhi ungqimba lwe-PE luvikela i-EVOH emswakama.Ngokuvamile zinokuqina okuhle kakhulu kokubhoboza okuvela ezingqimbeni ze-PA.Sekukonke, zidlula i-PA/PE elula ngomgoqo we-oxygen kanye nephunga ngaphandle kokunciphisa amandla okuvala.

•Izicelo:Izikhwama ze-vacuum ze-EVOH ezinezivimbelo eziphakeme zilungele inyama entsha/eqandisiwe, izinkukhu kanye nokudla kwasolwandle okumele kuthunyelwe kude noma kugcinwe isikhathi eside. Ziphinde zisebenzele ukudla okunenani eliphezulu noma okuzwela umoya-mpilo njengoshizi, amantongomane, izithelo eziphelelwe amanzi noma ukudla okulungiselelwe okuphezulu kanye namasosi. Kunoma yikuphi ukudla okubandayo noma okuqandisiwe lapho ikhwalithi (umbala, ukunambitheka, ukuthungwa) kufanele igcinwe khona, isikhwama se-EVOH siyisinqumo esiphephile.. Izinto ezibonakalayo kuhlekwenyama ebandayo kanye nobisi, kanye noketshezi (isobho, i-kimchi, amasoso) emabhokisini esikhwama.Ngamafuphi, khetha izikhwama ze-EVOH noma nini lapho udinga isithiyo esikhulu—izinto ezifana nemikhiqizo yenyama engaphansi kwe-vide noma isitoko sesikhathi eside.

•Ezinye Izithiyo:Amafilimu ambozwe nge-PVDC (asetshenziswa kwezinye izikhwama zoshizi noma ezincishisiwe zenyama) anikeza ukuvuleka okuphansi kwe-O₂, yize izinkinga zomthetho kanye nokucubungula zinciphise ukusetshenziswa kwe-PVDC..Amafilimu ensimbi e-vacuum (i-PET noma i-PA embozwe nge-aluminium) nawo athuthukisa isithiyo (bheka isigaba esilandelayo).

Izikhwama Zokushaja Ezine-Aluminium Foil (Ezenziwe Ngensimbi)

Ikhofi, itiye noma izinongo ezivalwe nge-vacuum zivame ukusebenzisa izikhwama ezine-aluminium ukuze zivikeleke kangcono. Izendlalelo ze-aluminium foil esikhwameni zinikeza isithiyo esiphelele ekukhanyeni, emoyeni kanye nomswakama. Izikhwama ezivamile ze-foil-vacuum zinezendlalelo ezintathu, isib. i-PET/AL/PE noma i-PA/AL/PE. Ifilimu yangaphandle ye-PET (noma i-PA) inikeza ukumelana nokubhoboza kanye namandla omshini, i-AL foil ephakathi ivimba igesi nokukhanya, kanti i-PE yangaphakathi iqinisekisa ukuvalwa kokushisa okuhlanzekile. Umphumela uba isithiyo esingcono kakhulu ekupakishweni kwe-vacuum: cishe akukho moya noma umhwamuko ongangena.

•Izakhiwo:Izikhwama ze-aluminium-laminate zingaba ziqinile kodwa zibe sesimweni esihle; zibonisa ukushisa nokukhanya, zivikele ekushintsheni kwe-UV kanye nokushisa. Zisinda futhi azibonakali, ngakho okuqukethwe kufihliwe, kodwa imikhiqizo ihlala yomile futhi ingangcoliswanga..Ziphatha kahle amafriji ajulile kanye nokugcwalisa okushisayo ngokulinganayo.(Qaphela: izikhwama ze-foil azikwazi ukufakwa kuhhavini ngaphandle kokuthi ziphathwe ngendlela ekhethekile.)

•Izicelo:Sebenzisa izikhwama ze-foil ezintweni ezinenani eliphezulu noma ezibola kakhulu. Izibonelo zakudala zifaka ikhofi netiye (ukugcina iphunga nokusha), ukudla okomisiwe okumpuphu noma okuqandisiwe, amantongomane, kanye namakhambi. Ekuhlinzekweni kokudla, izikhwama ze-sous-vide noma ze-boil-in-bag zivame ukusebenzisa i-foil. Ziphinde zivelele emithini nakumavithamini. Ezimweni zezimboni, izikhwama ze-foil vacuum zipakisha izingxenye zomswakama/ezizwela umoya kanye nezinto zikagesi..Empeleni, noma yimuphi umkhiqizo ozowohloka uma ubhekene nomoya-mpilo noma ukukhanya uyazuza nge-laminate ye-foil. Isibonelo, amaqabunga etiye agcwele i-vacuum (njengoba kuboniswe ngenhla) agcina ukunambitheka kwawo isikhathi eside kakhulu esikhwameni se-foil kunasepulasitikini engenalutho.

•Ukuhambisana Komshini:Izikhwama ze-aluminium foil zivame ukuba bushelelezi futhiezinye zelezi zikhwama zivalwe emishinini enzima. I-DJVACumshini wokupakisha we-vacuum wangaphandlebangakwazi ukucubungula lezi zikhwama ngaphandle kwenkinga.

Izicelo Zezimboni Nezokugcina Imibhalo

Nakuba ukudla kugxile kakhulu, izikhwama zokuhlanza ezivimbela kakhulu zinezinye izindlela zokusebenzisa:

•Izingxenye Ze-elekthronikhi Nezensimbi:Njengoba kuphawuliwe, izikhwama ze-vacuum ze-PA/PE noma ze-foil zivikela izingxenye ezizwela umswakama ngesikhathi sokuthunyelwa. Indawo yokuhlanza i-vacuum kanye ne-desiccant kungavimbela ukubola noma ukugqwala kwezingxenye zensimbi..Ngokungafani nokudla, lapha umuntu angageza nge-nitrogen ngaphambi kokuvala.Imishini ye-DJVAC (enezibambo nezilawuli ezifanele) iphatha lawa ma-foil ajiyile nomai-aluminiumizikhwama.

•Ukulondolozwa Kwemibhalo:Ukupakisha okugciniwe kuvame ukusebenzisa amafilimu angasebenzisi i-vacuum (njenge-polyethylene noma i-polyester/Mylar) ukuvimba umoya-mpilo kanye nezinambuzane.Ngokwakha isikhwama esingangeni moya, amaphepha agwema ukuphuzi nokukhunta.Isimiso esifanayo - ukunciphisa umoya-mpilo - siyasebenza njengasekudleni: iphakethe elingangeni moya landisa isikhathi eside.

•Imithi kanye Nezokwelapha:Amakhithi ezokwelapha ahlanzekile avaliwe nge-vacuum ezikhwameni ezinezivikelo eziphakeme. Izikhwama ze-PA/PE zivamile lapha, ngezinye izikhathi zinezimbobo zokudabuka. Ifilimu kumele ihlangabezane nezindinganiso ze-FDA noma zezokwelapha.

Kuzo zonke lezi zimo, isihluthulelo ukusebenzisa ifilimu elinganiswe ngokwendawo yomkhiqizo (isb. i-halogen-free for electronics, ikhwalithi yokugcina imibhalo).Imishini ye-vacuum ye-DJVAC ingaphatha izinhlobo ezahlukene zama-laminate ezikhwama kanye nosayizi, ngakho amakhasimende kufanele acacise ifilimu ayidingayo..

Ukukhetha Izinto Ezifanele Zesikhwama Sokuhlanzwa Kwe-Vacuum

Uma ukhetha isikhwama se-vacuum cleaner, cabanga ngalokhu okulandelayo:

•Izidingo Zesithiyo:Umkhiqizo kufanele uhlale umusha isikhathi esingakanani futhi ngaphansi kwaziphi izimo? Uma kudingeka isiqandisi sesikhashana kuphela, isikhwama esijwayelekile se-PA/PE noma se-PET/PE singase sanele.Uma ugcina iqhwa izinyanga eziningi noma imikhiqizo ebucayi kakhulu, sebenzisa i-EVOH noma ama-laminate e-foil ane-okuphansi kakhuluUkudluliselwa kwe-O₂.

•Ukuvikelwa Kwemishini:Ingabe into izoba nemiphetho ebukhali noma izophathwa ngendlela exakile? Bese ubeka phambili ukumelana nokubhoboza (ama-laminate acebile nge-nylon noma ukuthungwa okuhlanganisiwe).Izingxenye ezinkulu zezimboni noma inyama emathanjeni zidinga amafilimu aqinile.

•Indlela Yokuvala:Zonke izikhwama ze-vacuum zithembele ekuvaleni ukushisa.I-PE (LDPE noma i-LLDPE) iyisendlalelo esivamile sokuvala.Qinisekisa ukuthi izinga lokushisa lokuvala lesikhwama lihambisana nemingcele yokushisa yomshini wakho.Amanye amafilimu anezivikelo eziphakeme angadinga amazinga okushisa aphezulu okuvala noma ingcindezi enkulu yokubamba.

•Ukuphepha Kokudla kanye Nemithethonqubo:Sebenzisa amafilimu okudla avunyelwe yi-FDA/GB.I-DJVAC ibambisana nabahlinzeki bezikhwama abahlinzeka ngezinto eziqinisekisiwe, ezithinta ukudla. Ezimakethe zokuthumela kwamanye amazwe, amafilimu avame ukudinga imibhalo yokuthobela imithetho.

•Izindleko vs. Ukusebenza:Izikhwama ze-EVOH noma ze-foil ezinezivikelo eziphakeme zibiza kakhulu.Linganisa izindleko nezidingo zesikhathi sokuphelelwa yisikhathi.Isibonelo, amantongomane afakwe nge-vacuum ahloselwe ukuthunyelwa kwamanye amazwe angase afanele izikhwama ze-foil, kuyilapho ukuqandisa ekhaya kungasebenzisa izikhwama ze-PA/PE ezilula.

Empeleni, abaprosesa bavame ukuhlola izikhwama zesampula. Abakhiqizi abaningi bazohlinzeka ngama-roll noma amashidi okuhlola ukuze kuhlolwe amakhasimende..Chaza umkhiqizo wakho (isib. “izingcezu zenkukhu eziqandisiwe”), isikhathi esifunekayo sokufaka eshalofini, kanye nendlela yokupakisha ukuze uthole isakhiwo esinconywayo.

Isiphetho

Imishini yokufaka i-vacuum iyithuluzi eliguquguqukayo, kodwa idinga izinto ezifanele zesikhwama ukuze isebenze kahle.Imishini yokupakisha ye-vacuum ye-DJVAC ingasebenzisa zonke izinhlobo zezikhwama ezinkulu emakethe - kusukela ezikhwameni ze-PA/PE ezijwayelekile kuya ezikhwameni ze-EVOH ezinezithiyo eziphakeme kanye nama-laminate e-foil aqinile.Ngokuqonda izakhiwo zezinto ezibonakalayo (amandla okuvimbela, ukumelana nokushisa, ukuqina kokubhoboza) nokuzifanisa nokusetshenziswa (inyama, ushizi, ikhofi, amantongomane, njll.), abakhiqizi bangaqinisekisa ikhwalithi yomkhiqizo kanye nokusebenza kahle kwawo..Ngaphezu kwalokho, ukusebenzisa isikhwama esifanele nomshini ofanele (okufakwe uphawu noma okuyisicaba, igumbi noma ukumunca) kwandisa izinga le-vacuum kanye nokuqina kwesivalo. Ngamafuphi, uma usebenzisa umshini wokupakisha we-vacuum we-DJVAC, khetha izinto zesikhwama ezinikeza isivikelo esidingekayo somkhiqizo wakho futhi zihambisane nomklamo womshini.
