Izinto zokupakisha zokuthambisa ulwazi-ibhegi yemaski yobuso

Amanqaku aphambili oLawulo lweMveliso yeengxowa zokuPakisha iiMask zoBuso

Ubukhulu bengxowa yefilimu:eqhelekileyo 100microns-160microns,Ubukhulu befoyile ye-aluminiyam ecocekileyo yokusetyenziswa okudibeneyo ngokuqhelekileyo7microns

Imvelisoixesha lokukhokhela: kulindeleke ukuba ibe malunga neentsuku ezili-12

Alumiiniumifilimu:I-VMPET yimathiriyeli edityanisiweyo yokupakisha eyenziwe ngokutyabeka umaleko obhityileyo we-aluminiyam yesinyithi kumphezulu wefilimu yeplastiki kusetyenziswa inkqubo ekhethekileyo. I-advanteji yi-metallic luster effect, kodwa i-disadvantage yimpawu ezinqabileyo zomqobo.

1. Inkqubo yoShicilelo

Ukususela kwiimfuno zemarike yangoku kunye nembono yomthengi, iimaski zobuso zithathwa njengemveliso ephezulu, ngoko ke iimfuno zokuhombisa ezisisiseko zahlukile kwezo zokutya okuqhelekileyo kunye nokupakishwa kweekhemikhali zemihla ngemihla, ubuncinane "ziphezulu" zabathengi. ngengqondo. Ngoko ukuprinta, ukuthatha i-PET yoshicilelo njengomzekelo, ukuchaneka kwe-overprint kunye neemfuno ze-hue zokushicilelwa kwayo ubuncinane kwinqanaba eliphezulu kunezinye iimfuno zokupakisha. Ukuba umgangatho wesizwe kukuba ukuchaneka okuphambili kwe-overprint yi-0.2mm, ngoko ke izikhundla zesibini zokushicilela isikhwama sokupakisha ebusweni kufuneka zihlangabezane nalo mgangatho wokushicilela ukuze ulungelelanise ngcono iimfuno zabathengi kunye neemfuno zabathengi.

Ngokomahluko wombala, abathengi bokupakisha imaski yobuso bangqongqo kwaye baneenkcukacha ngakumbi kuneenkampani eziqhelekileyo zokutya.

Ke ngoko, kwinkqubo yoshicilelo, iinkampani ezivelisa ukupakishwa kwemaski yobuso kufuneka zithathele ingqalelo kulawulo loshicilelo kunye nombala. Kakade ke, kuya kubakho iimfuno eziphakamileyo zokushicilela ii-substrates ukuze zihambelane nemigangatho ephezulu yoshicilelo.

2.Inkqubo yokuLamination

I-Composite ilawula ubukhulu becala imiba emithathu: imibimbi edibeneyo, intsalela edibeneyo yokunyibilikisa, imingxuma edibeneyo kunye namaqamza kunye nezinye izinto ezingaqhelekanga. Kule nkqubo, le miba mithathu zizinto eziphambili ezichaphazela isivuno seengxowa zokupakisha imaski yobuso.

(1) Imibimbi edibeneyo

Njengoko kunokubonwa kwesi sakhiwo singentla, iingxowa zokupakisha imaski yobuso ikakhulu zibandakanya ukudityaniswa kwe-aluminiyam ecocekileyo. I-aluminiyam ecocekileyo iqengqeleke kwintsimbi ecocekileyo ibe kwiphepha elicekethekileyo elifana nefilimu, eyaziwa ngokuba yi "aluminium film" kushishino. Ubukhulu buphakathi kwe-6.5 kunye ne-7 μm. Ewe kunjalo, kukwakho neefilimu ezishinyeneyo zealuminiyam.

Iifilimu ezicocekileyo ze-aluminiyam zithandeka kakhulu kwimibimbi, ikhefu, okanye itonela ngexesha lenkqubo yokuthambisa. Ingakumbi oomatshini laminating ukuba ngokuzenzekelayo splice izinto, ngenxa izitenxo ekudibaneni oluzenzekelayo engundoqo iphepha, kulula ukuba zingalingani, kwaye kulula kakhulu ukuba ifilimu aluminiyam ukushwabana ngqo emva lamination, okanye nokufa.

Kwimibimbi, kwelinye icala, sinokuyilungisa kwi-post-process ukunciphisa ilahleko ebangelwa yimibimbi. Xa i-glue edibeneyo izinzile kwisimo esithile, ukuphinda-phinda kuyindlela enye, kodwa oku kukuphela kwendlela yokunciphisa; kwelinye icala, sinokuqala ngoyena nobangela. Nciphisa umthamo wokujija. Ukuba usebenzisa i-core yephepha elikhulu, umphumo wokujika uya kuba ulungele ngakumbi.

(2) Intsalela ye-solvent edibeneyo

Kuba ukupakishwa kwemaski yobuso ngokusisiseko kuqulethe i-aluminiyam okanye i-aluminiyam esulungekileyo, kwii-composites, ubukho be-aluminiyam okanye i-aluminiyam esulungekileyo inobungozi ekuguqukeni kwe-solvents. Oku kungenxa yokuba iimpawu zokuthintelwa kwezi zimbini zinamandla kunezinye izinto eziqhelekileyo, ngoko Kuyingozi kwi-volatilization of solvents. Nangona kuchazwe ngokucacileyo kwi-GB/T10004-2008 "i-Dry Composite Extrusion Compounding of Plastic Composite Films and Bags for Packaging" umgangatho: Lo mgangatho awusebenzi kwiifilimu zeplastiki kunye neengxowa ezenziwe ngezinto zeplastiki kunye nesiseko sephepha okanye i-aluminium foil.

Nangona kunjalo, okwangoku iinkampani zokupakisha imaski yobuso kunye neenkampani ezininzi zisebenzisa lo mgangatho wesizwe njengomgangatho. Kwiingxowa ze-aluminium foil, lo mgangatho nawo uyafuneka, ngoko ke uyalahlekisa ngandlel' ithile.

Ngokuqinisekileyo, umgangatho wesizwe awunazo iimfuno ezicacileyo, kodwa kusafuneka silawule iintsalela ze-solvent kwimveliso yangempela. Emva kwayo yonke loo nto, le yinqanaba elibaluleke kakhulu lolawulo.

Ngokubhekiselele kumava obuqu, kuyenzeka ukwenza uphuculo olusebenzayo malunga nokukhethwa kweglue, isantya somatshini wokuvelisa, ubushushu be-oveni, kunye nomthamo wokukhupha izixhobo. Ngokuqinisekileyo, lo mba ufuna uhlalutyo kunye nokuphuculwa kwezixhobo ezithile kunye neendawo ezithile.

(3) Umngxuma odibeneyo kunye namaqamza

Le ngxaki nayo inxulumene kakhulu ne-aluminium ecocekileyo, ngakumbi xa i-PET / AL isakhiwo esidibeneyo, kunokwenzeka ukuba sibonakale. Umphezulu odibeneyo uya kuqokelela "i-crystal point" -into efana ne-phenomena, okanye i-"bubble" efana ne-point-like phenomena. Ezona zizathu ziphambili zezi zilandelayo:

Ngokubhekiselele kwizinto ezisisiseko: Unyango oluphezulu lwezinto ezisisiseko alulungile, oluxhomekeke kwi-pitting kunye ne-bubbles; izinto ezisisiseko ze-PE zinamanqaku amaninzi ekristale kwaye inkulu kakhulu, eyona nto ibangela iingxaki. Kwelinye icala, i-particle aspect of inki nayo yenye yezinto. Iimpawu zokulinganisa iglue kunye neengqungquthela ezinqabileyo ze-inki nazo ziya kubangela iingxaki ezifanayo ngexesha lokudibanisa.

Ngaphezu koko, ngokubhekiselele ekusebenzeni komatshini, xa i-solvent ingaphumi ngokwaneleyo kwaye uxinzelelo oluxutywayo aluphezulu ngokwaneleyo, iziganeko ezifanayo ziya kwenzeka kwakhona, nokuba i-roller ye-gluing yesikrini ivaliwe, okanye kukho into yangaphandle.

Khangela izisombululo ezingcono kule miba ingentla kwaye ugwebe okanye uziphelise ngendlela ekujoliswe kuyo.

3. Ukwenza ingxowa

Kwinqanaba lolawulo lwenkqubo yemveliso egqityiweyo, sijonga ngokukodwa kwi-flatness yesikhwama kunye namandla kunye nokubonakala kokutywinwa komphetho.

Kwinkqubo yokwenza ingxowa egqityiweyo, ukugudisa kunye nokubonakala kunzima ukuyiqonda. Ngenxa yokuba inqanaba layo lokugqibela lobugcisa lichongwa ngokusebenza koomatshini, izixhobo, kunye nemikhwa yokusebenza kwabasebenzi, iingxowa zilula kakhulu ukuba zikrwelwe ngexesha lenkqubo yemveliso egqityiweyo, kwaye izinto ezingaqhelekanga ezifana nemiphetho emikhulu kunye encinci inokuvela.

Kwiingxowa zeemaski zobuso ezineemfuno ezingqongqo, ezi azivumelekanga ngokuqinisekileyo. Ukusombulula le ngxaki, sinokulawula umatshini ukusuka kowona mba usisiseko we-5S ukulawula isenzeko sokukrwela.

Njengeyona ndawo isisiseko solawulo lwendawo yokusebenzela, ukucocwa komatshini yenye yeziqinisekiso ezisisiseko zokuvelisa ukuqinisekisa ukuba umatshini ucocekile kwaye akukho zinto zangaphandle zivela kumatshini ukuze kuqinisekiswe umsebenzi oqhelekileyo nogudileyo. Ewe kunjalo, kufuneka sitshintshe ezona mfuno zisisiseko nezikhethekileyo zokusebenza kunye nemikhwa yomatshini.

Ngokwembonakalo, ngokweemfuno zokutywinwa komphetho kunye namandla okutywinwa komphetho, kuyafuneka ngokubanzi ukuba kusetyenziswe imela yokutywina enokwakheka okucolekileyo okanye imela yokutywina ecaba ukucinezela ukutywinwa komphetho. Esi sisicelo esikhethekileyo. Ikwaluvavanyo olukhulu kubaqhubi boomatshini.
