Ibhokisi lombala ngokuvamile lenziwa ngemibala eminingana. Inqubo yebhokisi lombala ngemva kokuphrinta igqamisa ukubukeka okuphelele nombala wezimpahla, futhi inikeza abathengi umuzwa oqinile wokubuka. Isetshenziswe kabanzi kwezokwelapha, izimonyo nezinye izimboni kanye nokupakishwa kwemikhiqizo nezinye izimboni. Lesi sihloko sihlelwa ngabakwaIphakethe le-Shanghai Rainbowukwabelana ngokuqukethwe okufanelekile kwebhokisi lombala inqubo yokunyathelisa ngemva kokunyathelisa kanye nezinkinga ezivamile.
Ibhokisi lombalaibhekisela ebhokisini lephepha eligoqwayo kanye nebhokisi lephepha likathayela elincane elenziwe ngekhadibhodi namakhadibhodi anothayela. Ngokuvamile isetshenziswa njengendlela yokupakisha ephakathi, phakathi kwephakethe langaphakathi nelangaphandle.
01 Inqubo yangemuva kokucindezela
Inqubo yokuphrinta yangemuva kwebhokisi lombala ihlanganisa i-bronzing, ukugcoba, ukuvanisha kwe-UV, ukupholisha, ukumboza ifilimu i-concave-convex, i-die-cutting nezinye izinqubo.
02 Amafutha amaningi
Umgomo wenqubo
I-metering roll iqondiswe futhi ijikeleza ngesivinini esingaguquki, futhi isiqondiso sokujikeleza siphambene nalokho kwe-coating roll; Ngale ndlela, ungqimba olungaphezulu lwe-coating roller lufana, indawo ephrintiwe ihlangene ne-coating roller axis surface, futhi ukugqoka kuhlanganiswe ngokulinganayo ngaphansi komphumela we-viscosity yokugqoka kanye nokucindezela kweqembu le-roller.
Uhlobo kanye nendlela yokomisa
Ngokusho kohlobo lwamafutha, ingahlukaniswa ngezinhlobo ezilandelayo:
1) Amafutha angaphezu kwamanzi
2) Amafutha acwebezelayo ngokweqile
3) Amafutha e-Superplastic
4) Amafutha agqamile
Indlela yokomisa uwoyela: ukomiswa kwe-infrared
Qaphela: Imikhiqizo enezinhlangothi ezimbili ezinamafutha kufanele ibekwe phezulu futhi yomiswe ngaphambi kokuba yamukelwe. Ngoba imikhiqizo enezinhlangothi eziphindwe kabili kulula ukunamathela
imfuneko yezobuchwepheshe
Ngaphezu kombala wayo ongenambala, ocwebezelayo, omiswe ngokushesha, ukumelana namakhemikhali nezinye izici, uwoyela ocwebezelayo kufanele futhi ube nezinto ezilandelayo:
1) Ifilimu inokucaca okuphezulu futhi ayishintshi umbala. Isithombe nombhalo ngeke kushintshe umbala ngemva kokoma. Ngaphezu kwalokho, akufanele ishintshe umbala noma ibe phuzi ngenxa yokuchayeka elangeni noma isetshenziswe isikhathi eside.
2) Ifilimu inokumelana okuthile kokugqoka.
3) Inokuguquguquka okuthile. Ifilimu ekhanyayo eyenziwe yinoma yiluphi uhlobo lwe-varnish ebusweni bendaba ephrintiwe kufanele igcine ukuqina okuhle ukuze ivumelane nokuguquguquka kwephepha noma iphepha, futhi ngeke ilimale, iqhekeze noma ihlulwe.
I-4) Ifilimu inokumelana okuhle kwemvelo. Akuvunyelwe ukushintsha ukusebenza ngenxa yokuxhumana ne-asidi ebuthakathaka noma isisekelo esibuthakathaka endaweni.
5) Inokunamathela okuthile ebusweni bendaba ephrintiwe. Ngenxa yethonya lenani elibalulekile lokuminyana kwesithombe esingaphezulu kanye nongqimba lukayinki wombhalo, ukunamathela okungaphezulu kwendaba ephrintiwe kuncipha kakhulu. Ukuze uvimbele ifilimu eyomile ukuthi ingaqhekeki futhi ixebuke ekusetshenzisweni ngemva kokumiswa, kuyadingeka ukuthi ifilimu ibe nokunamathela okuqinile, futhi ibe nokunamathela okuthile kuyinki kanye nezinto ezihlukahlukene ezisizayo zokuyinki.
6) Ukulinganisa okuhle nokubushelelezi kwefilimu. I-absorbency ebusweni, ubushelelezi kanye nokumanzisa kwezinto eziphrintiwe kuyahluka kakhulu. Ukuze wenze ukunamathela okucwebezelayo kube ifilimu ebushelelezi ezindaweni ezihlukene zomkhiqizo, kuyadingeka ukuthi uwoyela ocwebezelayo ube nesakhiwo esihle sokulinganisa futhi ifilimu ibushelelezi ngemva kokwakhiwa kwefilimu.
I-7) Kudingeka ukuthi kube nokuvumelana nezimo okubanzi ekucubungulweni kwangemuva kokucindezela. Okufana ne-gilding nokuphrinta isikrini.

05 Isembozo sefilimu
isifinyezo
Isembozo sefilimu yinqubo yokumboza ifilimu yepulasitiki phezu kwento ephrintiwe bese usebenzisa ingcina ukushisa bese uyicindezela ndawonye.
Inqubo yokumboza ihlukaniswe: okungukuthi, ukugqoka kanye nokugcoba
Njengamanje, okuvame ukusetshenziswa kakhulu ukunamathela okusheshayo e-China.
Ifilimu yokuhlanganisa esheshayo ingahlukaniswa ibe ifilimu esekelwe ngamafutha kanye nefilimu esekelwe emanzini ngokohlobo lweglue.
Umdwebo wesakhiwo womshini wefilimu wokuhlanganisa osheshayo.
iisici se-nfluence
I-1) Izinto zokunyathelisa zinethonya elikhulu kwikhwalithi yokumboza ifilimu
Ingaphezulu lihlanzekile. Umphumela wokumboza ifilimu wezinto ezinobukhulu obufanayo namandla okugoba aphezulu ulungile
I-2) Ithonya likayinki kwikhwalithi yokugqoka ifilimu lisobala kakhulu
Ungqimba lukayinki oluwugqinsi lwento ephrintiwe noma indawo enkulu yesithombe esiphrintiwe nombhalo kuzobangela ukuthi uyinki uvale izimbotshana zefayibha, uvimbe ukungena nokusabalalisa kokunamathelayo, futhi kwenze kube nzima ukuthi into ephrintiwe ibambelele kukho. ifilimu yepulasitiki, ejwayele ukuqhuma.
Uyinki ugcotshwa ngaphambi kokuba wome ngokuphelele. I-solvent enephuzu eliphezulu lokubilisa equkethwe kuyinki kulula ukunweba nokwelula ifilimu. Ngemuva kokuthi ifilimu iboshwe, umkhiqizo uzoqhuma futhi ukhiphe ifilimu.
3) Inqubo yokuphrinta ithinta ikhwalithi yokumboza ifilimu
Imikhiqizo ephrintiwe nge-inki evamile yegolide neyesiliva ayifanele ukumboza ifilimu, ngoba i-powder yensimbi ihlukaniswa kalula noyinki phakathi nenqubo yokomisa, futhi i-metal powder ehlukanisiwe izokwakha umgoqo phakathi kongqimba lweyinki kanye ne-adhesive, ethinta inhlanganisela ephumelelayo kokubili. Lo mkhiqizo uzoba namabhamuza ngemva kokubekwa isikhathi esithile
4) Ithonya lokushisa elizungezile kanye nomswakama
Izinguquko kumswakama wento ephrintiwe (ukumuncwa umswakama, ukuphelelwa amanzi) ikakhulukazi kwenzeka emaphethelweni omkhiqizo ngesikhathi sokucindezela okushisayo kanye ne-lamination, okungelula ukwakha ukunamathela okuhle nefilimu, ukukhiqiza imibimbi kalula, futhi kuthinte ukukhiqizwa okubushelelezi. yomkhiqizo.
Izidingo zezinto ezibonakalayo
Uma kuphezulu ukubonakala kwefilimu, kuba ngcono kakhulu ukuqinisekisa ukucaca okuhle kokuphrinta okumboziwe
Inokumelana okuhle kokukhanya futhi ayishintshi umbala ngaphansi kwesenzo sokukhanya isikhathi eside
Ukuze uxhumane nama-solvents, ama-adhesives, inki namanye amakhemikhali, kufanele ibe nokusimama okuhle kwamakhemikhali
Awekho amachashaza amhlophe, imibimbi, amaphinifa
Amandla angaphezulu azohlangabezana nezidingo zokucubungula zenqubo elandelayo, futhi amandla angaphezulu azoba makhulu kunama-dynes angama-38 uma edinga ukwenziwa ngethusi.
Amafilimu ajwayelekile afaka amafilimu e-PET kanye ne-BOPP
Ukuhlaziywa kwe-FAQ
I-curl yomkhiqizo ngemuva kokusika
I-1) Ukushuba kwefilimu kukhulu kakhulu, okwenza ifilimu ilula futhi ikhubaze. Idivayisi ye-tension yefilimu ingalungiswa
