Isingeniso: Ukuvumelana nezimo kwelebula yefilimu eshwabene kunamandla kakhulu.Ingahlotshiswa ngepulasitiki, insimbi, ingilazi nezinye iziqukathi zokupakisha.Ilebula lemikhono yefilimu i-Shrink idume kakhulu emakethe ngoba ingahlanganisa amaphethini ekhwalithi ephezulu kanye nomumo ohlukile.Lesi sihloko sabelana ngolwazi olufanele lokukhiqizwa kwelebula lefilimu elinciphayo, okuqukethwe okwereferensi yabangane:
Nciphisa ilebula yekhava yefilimu
Ilebula yemikhono yefilimu i-Shrink isethi yefilimu ephrintiwe ngefilimu yepulasitiki noma ishubhu lepulasitiki.
01 Izimpawu
I-1) Ukucubungula ilebula yemikhono yefilimu ye-shrinkage kulula, ukupakisha ukuvala, ukuvimbela ukungcola, ukuvikelwa okuhle kwempahla;
I-2) Isembozo sefilimu siseduze nezimpahla, ukupakishwa kuhlangene, futhi kungabonisa ukuma kwezimpahla, ngakho-ke kufanelekile izimpahla ezingavamile okunzima ukupakisha;
3) I-shrinkage film cover ilebula ilebula, ngaphandle kokusebenzisa i-adhesive, futhi ingathola ukubonakala obala okufanayo njengengilazi;
4) Ilebula yemikhono yefilimu eshwabene inganikeza ukuhlobisa okuyindilinga okungu-360° kwesiqukathi sokupakisha, futhi ingaphrinta ulwazi lomkhiqizo njengencazelo yomkhiqizo kulebula, ukuze abathengi baqonde ukusebenza komkhiqizo ngaphandle kokuvula iphakheji;
I-5) Ukuphrinta kwelebula le-sleeve yefilimu enciphayo kungokokuphrinta kwefilimu (umbhalo nombhalo kungaphakathi komkhono wefilimu), ongadlala indima yokuvikela i-blot, futhi ukumelana nokugqokwa kwelebula kungcono.
02 Dala amaphuzu abalulekile kanye nezimiso zokukhetha izinto ezibonakalayo
Idizayini yelebula
Ukwakhiwa kwephethini yokuhlobisa esembozweni sefilimu kufanele kunqunywe ngokuvumelana nobukhulu befilimu.Lapho siklama iphethini, kufanele siqale sicacise izinga lokuncipha elivundlile nelide lefilimu, kanye nezinga elivumelekile lokushwabana lendlela ngayinye ngemva kokupakishwa kanye nephutha elivumelekile lokuguga lephethini yokuhlobisa ngemva kokuncipha, ukuze siqinisekise ukuthi iphethini nombhalo ngemva kokuncipha kungabuyiselwa ngokunembile.
Ukuqina kwefilimu nokuncipha
Izinto ezisetshenziselwa ilebula yekhava yefilimu eshwabene kufanele igxile ezintweni ezintathu: izidingo zemvelo, ukujiya kwefilimu nokusebenza kokushwabana.
Ubukhulu befilimu bunqunywa ngokusekelwe endaweni yokusetshenziswa kwelebula kanye nesici sezindleko.Yebo, intengo ayiyona into enqumayo, njengoba ifilimu ngayinye ihlukile, futhi umsebenzisi kanye nephrinta yophawu lokuhweba kufanele bakhombe ifilimu nenqubo efaneleke kangcono kokokusebenza ngaphambi kokusayina inkontileka.Ngaphezu kwalokho, izinkomba ezidingekayo zemishini yokucubungula kanye nezinye izici zenqubo nazo zithinta ngokuqondile ukukhethwa kokuqina.Ugqinsi lwefilimu lwelebula yemikhono yefilimu eshwabene ngokuvamile luyi-30-70 μm, phakathi kwalo, ifilimu engu-40μm no-50μm isetshenziswa kakhulu.Ukwengeza, izinga lokuncipha kwefilimu liyadingeka, futhi izinga lokuncipha eliphambanayo (TD) liphezulu kunezinga lokuncipha kwe-longitudinal (MD).Izinga lokushwabana eliphambene lezinto ezivamile lingama-50% ~ 52% kanye no-60% ~ 62%, futhi lingafinyelela ku-90% ezimweni ezikhethekile.Izinga lokuncipha kwe-longitudinal kufanele libe ngu-6% ~ 8%.Uma wenza amalebula emikhonweni yefilimu eshwabene, zama ukukhetha izinto ezinokuncipha kwe-longitudinal encane.
Izinto zefilimu ezacile
Izinto eziyinhloko zokwenza amalebula ekhava yefilimu eshwabene ifilimu ye-PVC, ifilimu ye-PET, ifilimu ye-PETG, ifilimu ye-OPS, njll. Ukusebenza kwayo kungokulandelayo:
1) I-membrane ye-PVC
Ifilimu ye-PVC ingenye yezinto ezisetshenziswa kakhulu zefilimu.Intengo yayo iphansi, ububanzi bokuncipha kwezinga lokushisa bukhulu, isidingo somthombo wokushisa asiphezulu, umthombo wokushisa oyinhloko wokucubungula umoya oshisayo, i-infrared noma inhlanganisela yakho kokubili.Kodwa i-PVC inzima ukuyibuyisela kabusha, lapho ishisa igesi enobuthi, ayilungele ukuvikelwa kwemvelo, eYurophu, iJapane ivimbele ukusetshenziswa.
2) Ifilimu ye-OPS
Njengenye indlela yefilimu ye-PVC, ifilimu ye-OPS isetshenziswe kabanzi.Inokusebenza okuhle kokuncipha futhi ilungele imvelo.Imakethe yasekhaya yalo mkhiqizo iyashoda, futhi okwamanje i-OPS yekhwalithi ephezulu incike kakhulu ekuthengisweni kwamanye amazwe, osekuyisici esibalulekile esikhawulela ukuthuthukiswa kwawo.
3) Ifilimu ye-PETG
Ifilimu ye-PETG ye-copolymer ayizuzisi kuphela ekuvikelweni kwemvelo, futhi ingaba izinga lokuncipha elilungiswe ngaphambilini.Kodwa-ke, ngenxa yokuthi izinga lokuncipha likhulu kakhulu, lizonqunyelwa ukusetshenziswa.
4) PET ifilimu
Ifilimu ye-PET iwumsebenzi wefilimu owaziwa umhlaba wonke ongashisi nokushisa.Izinkomba zayo zobuchwepheshe, izakhiwo ezibonakalayo, ububanzi besicelo kanye nezindlela zokusebenzisa ziseduze nefilimu ye-PVC ye-thermal shrink, kodwa intengo ishibhile kune-PETG, ifilimu ye-unidirectional shrink ehamba phambili kakhulu.Izinga layo lokushwabana elivundlile lifinyelela ku-70%, izinga lokuncipha kwe-longitudinal lingaphansi kuka-3%, futhi elingenabo ubuthi, elingenakho ukungcola, liyinto efanelekile kakhulu yokuthatha indawo ye-PVC.
Ngaphezu kwalokho, ukushisa shrinkable ifilimu tube futhi ukukhiqizwa shrinkable ifilimu imikhono ilebula impahla, futhi ekukhiqizeni kungakhiwa ngaphandle suture.Uma kuqhathaniswa nefilimu eyisicaba evundlile, izindleko zokukhiqiza ilebula yemikhono yefilimu eshwabene eneshubhu yefilimu eshwabene ukushisa iphansi, kodwa ukuphrinta ebusweni bomzimba weshubhu kunzima kakhulu ukukufeza.Ngesikhathi esifanayo, izithombe nezithombe zelebula ye-tube yefilimu eshisa ukushisa ingaphrintwa kuphela ebusweni befilimu, okulula ukugqoka ngesikhathi sokuthutha nokugcinwa, ngaleyo ndlela kuthinte umphumela wokupakisha.
03 umkhiqizo ophelile
Ukuphrinta
Phrinta kufilimu ekhethiwe.Njengamanje, ukuphrinta kwefilimu ye-shrinkage ikakhulukazi kusebenzisa ukuphrinta kwe-intaglio, kusetshenziswa oyinki abasuselwa ku-solvent, okulandelwa ukuphrinta kwe-flexographic.Ngokuthuthuka kobuchwepheshe bokuphrinta be-flexo, imibala yokuphrinta igqamile futhi icacile, iqhathaniswa nokuphrinta kwe-gravure, ene-gloss enzima nephezulu ye-gravure.Ngaphezu kwalokho, ukuphrinta kwe-flexo kusetshenziswa uyinki osuselwe emanzini, okulungele ukuvikelwa kwemvelo.
Ukusika
Ngomshini wokusika osebenza kahle kakhulu, ifilimu ye-reel ephrintiwe ihlukaniswa ngobude, futhi ingxenye enqenqemeni yefilimu iphathwa ukuze ibushelelezi, isicaba futhi ingabi crimp.Uma usebenzisa ama-scutters, kufanele kukhokhwe ukunakwa ukuze ugweme i-blade eshisayo, ngoba i-hot blade izobangela ukuba ifilimu inqunywe ingxenye yombimbi.
Ukuthunga
Ifilimu eyisikiwe yayishuthulwe phakathi nendawo ngomshini wokuthunga, futhi umlomo weshubhu waboshelwa ukwenza umkhono wefilimu odingekayo ukuze ufakwe.Isibonelelo sezinto ezibonakalayo esidingekayo sokuthunga sincike ekunembeni kwe-suture kanye nekhono lomsebenzisi.Isibonelelo esiphezulu se-suturing ngu-10mm, ngokuvamile u-6mm.
Ukusika okuphambene
Umkhono wefilimu upakishwa ngaphandle kwempahla futhi usikwe ngokuvundlile ngokosayizi wokupakisha nge-scutter.Ifilimu ye-shrinkage ekushiseni okufanelekile kokushisa, ubude nobubanzi bayo buyoba nokufiphaza okubukhali (15% ~ 60%).Ngokuvamile kudingeka ukuthi usayizi wefilimu ube mkhulu ngo-10% kunosayizi omkhulu womumo wempahla.
Ukushisa kuyashwabana
Shisisa ngephaseji elishisayo, kuhhavini oshisayo noma isibhamu sesifutho somoya oshisayo.Ngalesi sikhathi, ilebula le-shrink izoncipha ngokushesha eduze kohlaka lwangaphandle lwesitsha, futhi uhlaka lwangaphandle lwesitsha lunamathele kakhulu, lwenza ungqimba oluvikelayo lwelebula oluhambisana ngokuphelele nokuma kwesiqukathi.
Enqubweni yokukhiqiza ilebula lemikhono yefilimu eshwabenekayo, ukutholwa okuqinile kwenqubo ngayinye kufanele kwenziwe umshini wokuhlonza okhethekile ukuze kuqinisekiswe ukunemba kokukhiqiza.
04 Ububanzi besicelo
Ukuguquguquka kwelebula le-shrinkage kunamandla kakhulu, okungasetshenziselwa ukuhlobisa indawo kanye nokuhlobisa ngokhuni, iphepha, insimbi, ingilazi, i-ceramic nezinye iziqukathi zokupakisha.Isetshenziswa kabanzi ekufakweni nasekuhlobiseni ukudla, imikhiqizo yansuku zonke yamakhemikhali nemikhiqizo yamakhemikhali, njengazo zonke izinhlobo zeziphuzo, izimonyo, ukudla kwezingane, ikhofi nokunye.Emkhakheni wamalebula ezidakamizwa, iphepha liseyi-substrate eyinhloko, kodwa ukuthuthukiswa kokufakwa kwefilimu kuye kwanda ngokushesha.Njengamanje, isihluthulelo sokuthuthukiswa kwelebula lemikhono yefilimu eshwabeneyo ukunciphisa izindleko, ngale ndlela kuphela okungathuthukisa ukuncintisana nokulwela isabelo semakethe esikhulu.
