Ilebula le-Shrink livumelana nezimo kakhulu, ipulasitiki, insimbi, ingilazi nezinye iziqukathi zokupakisha zingahlotshiswa, ilebula yomkhono wefilimu ishwabe ngenxa yokuhlanganiswa kwamaphethini ekhwalithi ephezulu kanye nokumodela okuhlukile, okuthandwa kakhulu emakethe.Leli phepha lichaza izici nezinzuzo zelebula yefilimu efinyezwayo kanye nomgomo wokukhetha izinto ezibonakalayo, okuqukethwe okuyireferensi yabangane:
Nciphisa ilebula yemikhono yefilimu
Isethi yamalebula yefilimu eshrinkable empeleni ingeyesigaba sefilimu encipha ukushisa, ifilimu yepulasitiki noma amalebula avelayo aphrintwe epayipini lepulasitiki, ikakhulukazi ahlanganisa i-PE, PVC, PET, njengefilimu yohlobo oluvamile eshwabanisa ukushisa, ngenxa yokuthi isethi yefilimu eshwabeneyo. kuyindlela yokwelula enqubweni yokukhiqiza, futhi kuyinqubo yokusebenzisa ukuncipha kokushisa kwefilimu yepulasitiki ye-thermoplastic.Ngakho-ke, ngaphambi kokuklanywa kwephethini engaphezulu, kufanele sicabangele izinga lokuncipha elivundlile nelide lezinto ezibonakalayo, kanye nephutha lokuguquguquka elivunyelwe kuzo zonke izinhlangothi zombhalo womhlobiso ngemva kokufinyela, ukuze kuqinisekiswe ukuncishiswa okunembile kwephethini. , umbhalo kanye nekhodi yebha kufihlwe esitsheni.
01 Aizinzuzo
Ilebula ye-Shrink-wrap ilebula yesethi yefilimu ephrintwe ngefilimu yepulasitiki noma ishubhu lepulasitiki.Inezici ezilandelayo:
I-1) Ukucubungula ilebula ye-sleeve yefilimu yefilimu kulula, ukupakisha ukuvala, ukulwa nokungcola, ukuvikela okuhle kwezimpahla;
I-2) Isembozo sefilimu siseduze nezimpahla, iphakheji ihlangene, futhi ingabonisa ukuma kwempahla, ngakho-ke ifanele izimpahla ezingavamile okunzima ukupakisha;
3) Nciphisa ilebula yelebula yemikhono yefilimu, ngaphandle kokusebenzisa ingcina, futhi ingathola ukubonakala obala okufanayo njengengilazi;
4) Ilebula eligoqelwe ngokuncipha linganikeza ukuhlobisa okungu-360° kwesiqukathi sokupakisha, futhi lingaphrinta ulwazi lomkhiqizo njengencazelo yomkhiqizo kulebula, ukuze abathengi baqonde ukusebenza komkhiqizo ngaphandle kokuvula iphakheji;
5) Ukuphrinta kwelebula yomkhono wefilimu enciphayo kungowokuphrinta kwefilimu (umbhalo nesithombe kungaphakathi komkhono wefilimu), ongavikela umbono futhi unokumelana kangcono nokugqoka.
02 Izimiso zokudizayina ezibalulekile kanye nezimiso zokukhetha izinto ezibonakalayo
Idizayini yelebula
Ukwakhiwa kwephethini yokuhlobisa kwifilimu kufanele kunqunywe ngokuvumelana nobukhulu befilimu.Lapho uklama iphethini, kuyadingeka ukucacisa izinga lokuncipha eliguquguqukayo nelide lefilimu, kanye nezinga elivumelekile lokuncipha ohlangothini ngalunye ngemva kokupakisha kanye nephutha elivunyelwe lokuguquguquka lephethini yokuhlobisa ngemva kokuncipha, ukuze kuqinisekiswe ukuthi iphethini nombhalo ngemva kokuncipha kungabuyiselwa ngokunembile.
Ukuqina kwefilimu nokuncipha
Izinto ezisetshenziselwa amalebula ekhava yefilimu ashwabenekayo kufanele zigxile ezintweni ezintathu: izidingo zemvelo, ukujiya kwefilimu nokusebenza kokuncipha.
Ubukhulu befilimu bunqunywa ngokusekelwe emkhakheni wokusetshenziswa kanye nezici zezindleko zelebula.Yebo, intengo ayiyona into enqumayo, njengoba ifilimu ngayinye ihlukile futhi kokubili umsebenzisi kanye nephrinta yelebula kufanele kucace ngefilimu kanye nenqubo efaneleke kangcono kokokusebenza ngaphambi kokungena ngemvume.Ngaphezu kwalokho, inkomba edingwa imishini yokucubungula kanye nezinye izici zenqubo nazo zithinta ngokuqondile ukukhethwa kobukhulu.Ngokuvamile kuyadingeka ukuthi ubukhulu befilimu belebula ye-shrink-sleeve ibe ngu-30-70 μm, phakathi kwayo u-40μm no-50μm asetshenziswa kakhulu.
Ukwengeza, izinga lokuncipha kwefilimu linezidingo ezithile, futhi izinga lokuncipha kwe-lateral (TD) lingaphezulu kwesilinganiso sokuncipha kwe-longitudinal (MD).Ukuncipha okuphambene kwezinto ezivamile kungama-50% ~ 52% kanye no-60% ~ 62%, futhi kungafinyelela ku-90% ezimweni ezikhethekile.Izinga lokuncipha kwe-longitudinal liyadingeka ku-6% ~ 8%.Lapho wenza amalebula emikhonweni yefilimu eshwabene, izinto ezinokuncipha kwe-longitudinal encane kufanele zikhethwe ngokusemandleni.
03 Izinto zefilimu
Izinto zokwenza ilebula yekhava yefilimu eshwabene yifilimu ye-PVC (PVC), ifilimu yesilwane (i-polyester), ifilimu yesikhonkwane (i-polyester elungisiwe), ifilimu ye-ops (i-polystyrene ene-oriented), njll. Ukusebenza kwayo kungokulandelayo:
Ifilimu ye-PVC ye-PVC
ifilimu iyinto esetshenziswa kakhulu ifilimu njengamanje.Ishibhile, inebanga elikhulu lokuncipha kwezinga lokushisa futhi ayizona izidingo eziphezulu zomthombo wokushisa.Umthombo oyinhloko wokushisa wokucubungula inhlanganisela yomoya oshisayo, ukukhanya kwe-infrared noma kokubili.Kodwa-ke, i-PVC inzima ukuyibuyisela kabusha, lapho igesi evuthayo, engahambisani nokuvikelwa kwemvelo, ivinjelwe eYurophu naseJapane.
OPSifilimu
Njengokuthatha indawo yamafilimu e-PVC, amafilimu e-OPS asetshenziswe kabanzi.Ukusebenza kwayo kokuncipha kuhle, futhi kuhambisana nokuvikelwa kwemvelo.Imakethe yasekhaya yalo mkhiqizo iyashoda, futhi okwamanje, i-OPS yekhwalithi ephezulu incike kakhulu ekungenweni kwamanye amazwe, osekuyisici esibalulekile esikhawulela ukuthuthukiswa kwawo.
PETGifilimu
Ifilimu ye-PETG ye-copolymer ayigcini nje ngokusiza ukuvikelwa kwemvelo, kodwa futhi ingalungisa izinga lokuncipha kusengaphambili.Kodwa-ke, ngenxa yokuncipha ngokweqile, izophinde ibe nomkhawulo ekusetshenzisweni.
PETifilimu
Ifilimu ye-PET iyifilimu eyaziwa emhlabeni wonke yohlobo lwe-thermal shrinkage.Izinkomba zayo zobuchwepheshe, izakhiwo ezibonakalayo, ububanzi bohlelo nezindlela zokusetshenziswa ziseduze nefilimu ye-PVC yokunciphisa ukushisa okushisayo, kodwa ishibhile kune-PETG, okuyifilimu yokunciphisa unidirectional ehamba phambili kakhulu okwamanje.Izinga layo lokushwabana eliphambanayo lingama-70%, izinga lokuncipha kwe-longitudinal lingaphansi kuka-3%, futhi alinabo ubuthi futhi alingcolisi, okuyizinto ezifanele kakhulu ukufaka esikhundleni se-PVC.
04 Ukuphrinta kwelebula yekhava yefilimu Kuphrintiwe kumafilimu akhethiwe.
Njengamanje, ukuphrinta komkhono wefilimu we-shrinkage kusetshenziswa kakhulu ekuphrinteni kwe-gravure, uyinki wokuphrinta we-solvent, okulandelwa ukuphrinta okuguquguqukayo.Ngokuthuthuka kobuchwepheshe be-flexo, umbala wokuphrinta ugqamile futhi ucacile, ungaqhathaniswa nokuphrinta kwe-gravure, nge-gloss enzima nephezulu ye-gravure.Ngaphezu kwalokho, i-flexo isebenzisa i-inki esekelwe emanzini, evumelana kakhulu nokuvikelwa kwemvelo.Ukusika ngomshini wokusika wokusebenza okuphezulu kuzosetshenziselwa ukusika ifilimu ye-reel ephrintiwe impahla yokusika i-longitudinal, futhi ingxenye enqenqemeni yefilimu izocutshungulwa ukuze ibushelelezi, ilula futhi ingabi yi-curly.Uma usebenzisa umshini wokusika, qaphela ukugwema ukushisa i-blade, ngoba i-blade eshisayo ingabangela ukuba ifilimu inqunywe ukuze ishwabene.I-suture yefilimu ngemuva kokusikwa kwe-longitudinal yenziwa umshini we-suture, futhi umlomo we-tube uhlanganiswe ukuze wenze umkhono we-membrane odingekayo wokupakisha.Imajini ebalulekile edingekayo ukuze umthungo uncike ekunembeni kwe-suture kanye nekhono lomsebenzisi.Isilinganiso esiphezulu esinconywayo sokuthunga singu-10mm, ngokuvamile sibe ngu-6mm.Ukusika okuphambene nokusonga ikhava yefilimu ngaphandle kwempahla, nokusika ifilimu ngokuvundlile ngokosayizi wayo wokupakisha.Emazingeni okushisa afanele, ubude nobubanzi befilimu yokuncipha kuzoncipha kakhulu (15% ~ 60%).Ngokuvamile, usayizi wefilimu udingeka ukuthi ube mkhulu ngo-10% kunosayizi omkhulu womumo womkhiqizo.Ukuncipha kokushisa kushiswa ngephaseji elishisayo, kuhhavini oshisayo, noma isibhamu sesifutho somoya oshisayo.Kuleli qophelo, ilebula yokuncipha izoshwabana ngokushesha eduze komugqa wangaphandle wesiqukathi, ilingane ngokuqinile nomkhonto ongaphandle wesiqukathi, yakhe ungqimba oluvikelayo lwelebula oluhambisana ngokuphelele nokuma kwesiqukathi.Enqubweni yokukhiqiza ilebula lemikhono yefilimu ye-shrinkage, kuyadingeka ukwenza ukutholwa okuqinile kwenqubo ngayinye ngomshini wokuthola okhethekile ukuze kuqinisekiswe ukunemba kokukhiqiza.I-scope esebenzayo yelebula ye-shrink ivumelana nezimo kakhulu, ingasetshenziselwa ukuhlobisa ngaphezulu, umhlobiso wezinkuni, iphepha, insimbi, ingilazi, izitsha zobumba kanye nezinye iziqukathi zokupakisha, ezisetshenziswa kakhulu ekudleni, emikhiqizweni yansuku zonke yamakhemikhali, imikhiqizo yamakhemikhali yokupakisha kanye nomhlobiso, njengeziphuzo ezinhlobonhlobo, izimonyo, ukudla kwezingane, ikhofi nokunye.
