Ifilimu Yepulasitiki Yangokwezifiso Ifinyeza Ibhodlela Lokupakisha I-PVC Ukushisa I-Sleeve Shrinking Sleeve ilebula yokushwabana kwebhodlela lesiphuzo

Ilebula yefilimu encipha ngokushisa ilebula yefilimu ephrintwe ngefilimu yepulasitiki noma ngeshubhu lepulasitiki elinoyinki okhethekile. Phakathi nenqubo yokulebula, lapho kushisa (cishe 70°C), ilebula eshwabeneyo izolandela ngokushesha umkhonto wangaphandle wesiqukathi. Amalebula efilimu ashwabenekayo, ashwabenekayo, afaka phakathi imikhono eshwabene kanye namalebula okugoqa ashwaqayo.

Amalebula efilimu ashwabenekayo, ashwabenekayo, afaka phakathi imikhono eshwabene kanye namalebula okugoqa ashwaqayo.
Ilebula yemikhono eshwabene ilebula eyicylindrical eyenziwe ngefilimu eshwabana ukushisa njengento eyisisekelo ngemva kokuphrinta. Inezici zokusetshenziswa okulula futhi ilungele kakhulu iziqukathi ezimise okukhethekile. Amalebula emikhono yokunciphisa ngokuvamile adinga ukusetshenziswa kwezinto ezikhethekile zokulebula ukuze kufakwe umkhono ophrintiwe esitsheni. Okokuqala, izinto zokulebula zivula ilebula yemikhono eyi-cylindrical evaliwe, okungenzeka ukuthi ngezinye izikhathi idinga ukushaywa; ngokulandelayo, ilebula lomkhono linqunywa usayizi ofanele futhi linemikhono esitsheni; bese ukwelashwa kokushisa kusetshenziswa isitimu, i-infrared noma iziteshi zomoya oshisayo , ukuze ilebula yemikhono inamathele ngokuqinile ebusweni besiqukathi.
Ngenxa yokucaca okuphezulu kwefilimu ngokwayo, ilebula inombala ogqamile kanye nokucwebezela okuhle. Kodwa-ke, ngenxa yokuthi kufanele inciphe ngesikhathi sokusetshenziswa, kunenkinga yokuguqulwa kwephethini, ikakhulukazi emikhiqizweni ephrintiwe ngamalogo webhakhodi. Kufanele idlule ekuklanyweni okuqinile kanye nokulawulwa kwekhwalithi yokuphrinta, ngaphandle kwalokho ikhwalithi yebhakhodi ngeke ifaneleke ngemva kokukhubazeka kwephethini. Amalebula okugoqa anciphisa angasetshenziswa kusetshenziswa okokusebenza okujwayelekile kokulebula, okudinga ukusetshenziswa kwezinamatheliso namazinga okushisa aphezulu. Ngesikhathi senqubo yokuncipha, njengoba i-adhesive engxenyeni egqagqene yefilimu izodala ukucindezeleka, kungcono ukusebenzisa i-adhesive eshisayo encibilikayo.
Ilebula yefilimu encipha ukushisa iyingxenye yemakethe yelebula, ekhula ngokushesha, futhi isabelo sayo semakethe siyakhula. Indawo ekhanyayo embonini yokuphrinta ilebula. Kubikezelwa ukuthi imakethe yamafilimu yasekhaya encipha ukushisa izokhula ngenani elingaphezu kwama-20% eminyakeni emihlanu ezayo.
Imboni yokudla iyimakethe enkulu kunazo zonke yokupakisha okunciphile. Ifilimu encishiswa ukushisa isetshenziswa kakhulu ekufakweni kokudla okuhlukahlukene okusheshayo, ukudla okune-lactic acid, iziphuzo, ukudla okuncane, amathini kabhiya, amawayini ahlukahlukene, imikhiqizo yezolimo neseceleni, ukudla okomile, imikhiqizo yendabuko, njll. Isisekelo samakhasimende selebula yefilimu eshwabana. imakethe ikakhulukazi izinkampani ezinkulu zezimpahla zabathengi ezihamba ngokushesha, njenge-Procter & Gamble, Unilever, Shanghai Jahwa, njll., imikhiqizo yazo ekumaqoqwana amakhulu futhi edinga ukuphrinta bukhoma isikhathi eside. Ukutshalwa kwezimali kokuqala kokuphrinta kwe-gravure kuphezulu, kodwa ukuqina okuphezulu kwepuleti le-gravure kanye nezindleko eziphansi ezihambisanayo kuyenza ibe yinketho yokuqala yokushwabana kwefilimu yokuphrinta. Ngaphezu kwalokho, ingxenye yesithombe esisepuletini yokunyathelisa i-concave, ngakho-ke kungase kutholakale ungqimba lukayinki oluqinile, imibala egqamile nezingqimba ezicebile.
Ngokukhuthazwa kokunyathelisa kwe-flexographic, amanye amafilimu anciphisa aphinde aphrintiwe ngokuphrinta kwe-flexographic, ikakhulukazi izinto ze-PE ezingakwazi ukumelana nokucindezeleka okukhulu, futhi iningi labo lisebenzisa imishini yokunyathelisa ye-CI-type flexographic. Emkhakheni ongewona owokudla, ukusetshenziswa kwamalebula efilimu anciphayo kuyancipha usuku nosuku, njengamalebula nezigqoko zamabhodlela, ama-seal, izimonyo, imithi, imikhiqizo yansuku zonke yamakhemikhali, izinto zokubhala, izinto zasekhishini, izidingo zansuku zonke, njll. Ngesikhathi esifanayo, isetshenziswe kabanzi emikhiqizweni ye-ceramic, amasethi wetiye, izingxenye zemishini, izinto zokwakha kanye nezinto zokuhamba.
