Zolemba zodzimatirira ndizofunikira kwambiri zosindikizira zomwe zimagwiritsidwa ntchito kwambiri pakuyika zinthu., mayendedwe azinthu, ndi zizindikiro zosiyanasiyana. Muzosindikiza zomatira zilembo, lamination ndi mgwirizano wovuta kwambiri. Ikhoza kuteteza chizindikiro pamwamba, kuonjezera durability, ndi kusintha aesthetics, potero kuwongolera moyo wautumiki ndi mtundu wa zilembo zodzimatira. Nkhaniyi idzafotokozera ndondomeko ya lamination ndi njira yodzipangira zolemba pambuyo pa kusindikiza, cholinga chothandiza owerenga kumvetsetsa njira zosiyanasiyana za lamination, mfundo zaukadaulo, ndi kusankha zinthu, komanso momwe mungadziwire njira yolondola ya lamination kuti muwonetsetse kuti ndi yabwino komanso yodalirika.
Udindo wa Label Lamination
Zophimba zilembo zimagwiritsidwa ntchito kuteteza zilembo kuti zisawonongeke zachilengedwe monga madzi, Kuwala kwa UV, abrasion, ndi zina. Powonjezera filimu yoteteza bwino pamwamba pa chizindikirocho, mutha kukulitsa moyo wa cholembera ndikusunga mawonekedwe ake momveka bwino. Kuyika ma label kumathanso kukulitsa kulimba kwa zilembo ndikuletsa zithunzi kapena zolemba pamawu kuti zisazimire pakapita nthawi. Laminates amaperekanso chitetezo chowonjezera, kuonetsetsa kuti zilembo siziwonongeka panthawi yotumiza ndi kusungirako. Ubwino wonsewu ukhoza kukulitsa luso lamakasitomala, potero kukulitsa chidziwitso cha mtundu.
Laminated Material
The lamination wa zomatira zolemba zambiri amagwiritsa ntchito zipangizo zotsatirazi:
Mafilimu a Polyester (PET): Izi ndi zolimba komanso zosagwira madzi, ndipo imapereka kusindikiza kwapamwamba kwa zithunzi ndi zolemba.
Filimu ya polypropylene (PP): Zopepuka komanso zowonekera kwambiri, nkhaniyi imapereka chitetezo chokhazikika. Kanema wa Composite wowonekera bwino kwambiri wa PP ndizomwe zimagwiritsidwa ntchito kwambiri. Chifukwa chake ndikuti PP ndi yotsika mtengo komanso yolimba kuposa zida zina zingapo.
Mafilimu a Polyvinyl Chloride (Zithunzi za PVC): Zinthu izi ndi zachuma, koma osakonda zachilengedwe kuposa zida za PET kapena PP.
Filimu ya polyethylene (PE): Izi ndi zofewa komanso zoyenera kuyika zilembo pamalo opindika kapena osakhazikika.
Chifukwa cha mtengo wofunikira, ❖ kuyanika kwa zida zopukutira pamapepala kumasinthidwa ndi ukadaulo wa glazing. M'makampani opanga ma label, pamene varnish sangathe kukwaniritsa kuwala ndi matte zofunika, lamination ndi njira yolunjika kwambiri. Titha kusankha zinthu zoyenera zopangira ma lamination malinga ndi mawonekedwe osiyanasiyana ogwiritsira ntchito kuti tiwonetsetse kuti chizindikirocho chimapeza chitetezo chokwanira komanso cholimba..
Laminating Njira
Lamination lamination njira zambiri anawagawa pepala kudyetsedwa lamination ndi mpukutu zinthu lamination. Mapepala odyetsedwa ndi mapepala amapangidwa ndi laminated pa makina opangira laminate, ndipo mpukutuwo umakhala ndi laminated pa siteshoni ya laminating ya makina olembera kapena pamakina apadera a laminating. Njira ziwiri zokutira zafotokozedwa pansipa:
- Mapepala a Laminated
Lamination ya Sheetfed imaphatikizapo kuyika zilembo pa pepala la lamination ndi kugwiritsa ntchito kutentha ndi kukakamiza kuti agwirizane ndi lamination ndi kulemba pamodzi.. Njirayi ndi yoyenera pamikhalidwe yomwe zilembo zamunthu zimafunikira kupangidwa laminated, monga pamene malemba ali a kukula kosiyana kapena kagwiridwe kapadera kakufunika pa zolembazo. Lamination yopangidwa ndi Sheetfed imatha kuchitidwa pogwiritsa ntchito ma laminators amanja kapena odziyimira pawokha.
Pali njira ziwiri zolembera zolemba zomatira papepala, ndicho ❖ kuyanika pompopompo lamination ndi chisanadze ❖ kuyanika filimu lamination.
1)Njira yophatikizira yopaka pompopompo kuphatikizika ndi motere: choyamba, zomatira zimakutidwa pamwamba pa filimu ya BOPP roll, ndi zosungunulira mu zomatira ndi volatilized mwa kuyanika chipangizo, ndiyeno pepala la pepala limaphatikizidwa ndi filimu yopukutira pamalo ophatikizira. Zophatikiza, awiriwo amakhala amodzi pansi pa extrusion ya wodzigudubuza otentha, ndipo ndondomeko yokutira filimu yatha.
2)filimu yophimbidwa kale imatanthawuza kuyikapo zomatira kapena zomata pamwamba pa filimuyo.. Pali mitundu iwiri ya mafilimu, otentha Sungunulani zomatira mtundu ndi kuthamanga tcheru mtundu. The laminating makina okonzeka ndi kutentha embossing wodzigudubuza, ndi chisanadze TACHIMATA filimu kukhudzana ndi pepala pa lamination. Pansi pa zochita za otentha kukanikiza wodzigudubuza, zomatira zasungunuka, kotero kuti filimu ndi pepala zigwirizane kukhala chimodzi. Ngati mumagwiritsa ntchito filimu yosakanikirana ndi zovuta, mutha kuzimitsa magetsi otenthetsera ndikungodalira kukakamiza kwa kompositi.
- Roll Material Lamination
Pereka zinthu lamination ndi kusindikiza mpukutu zinthu filimu ndi kulemba pamodzi, ndiyeno kudutsa iwo pamodzi kudzera laminating makina kwa kutentha ndi kuthamanga mankhwala. Njirayi ndi yoyenera kupanga zolemba zambiri, zomwe zingathe kupititsa patsogolo kupanga bwino komanso kuchepetsa ndalama. Lamination wa zipangizo ukonde akhoza kuchitidwa mtanda kapena mosalekeza kupanga.
Web lamination nthawi zambiri amagawidwa mu mitundu iwiri: filimu yapansi panthaka yokhala ndi filimu yophatikizika komanso yopanda pake yokhala ndi filimu yophatikizika.
1)Kuyimilira kwa pepala lopangidwa ndi filimu kumatanthawuza kuphatikizira pepala lothandizira kutsogolo kapena kumbuyo kwa pepala., ndiyeno ❖ kuyanika wosanjikiza wa zomatira kapena laminating zakuthupi pa akuchirikiza pepala, ndiyeno kumamatira cholembedwapo. Lamination yopangidwa ndi mapepala opangidwa ndi mapepala ndi njira yachikhalidwe yopangira, zomwe zalowedwa m'malo ndi njira yogwiritsira ntchito filimu yamagulu a mapepala opanda pake m'zaka zaposachedwa.
2)Laminating mfundo ya filimu yophatikizika popanda pepala pansi kwenikweni ndi yofanana ndi ya filimu yophatikizika ndi pepala pansi.. Mafilimu ochiritsira amapangidwanso ndi kusalala kwa pamwamba (kupanikizika pamwamba) zake zomwe kuti zilowe m'malo mwa pepala lothandizira. Pambuyo zomatira kumangirizidwa pamwamba, imatha kusenda popanda kusiya zomatira zilizonse. Zomwe zimagwiritsidwa ntchito popanga filimu yopanda malire nthawi zambiri zimakhala filimu yotsika kwambiri ya BOPP. Mtengo wa filimu yopanda malire ya pepala ndi yotsika, ndipo ndizomwe zimagwiritsidwa ntchito kwambiri pakali pano. Ubwino wa kompositi yamakanema yopanda malire ndikuti imatha kupititsa patsogolo kupanga bwino, kuchepetsa zinyalala popanga, ndipo pa nthawi yomweyo kusintha mankhwala khalidwe.
Kumene, ziribe kanthu kuti lamination njira yomwe imagwiritsidwa ntchito, wosanjikiza wotetezera ukhoza kupangidwa pamwamba pa chizindikirocho kuti ateteze chizindikiro ku kuwonongeka kwa chilengedwe.
Muzosindikiza zomatira zilembo, lamination ndi sitepe yofunika kwambiri, chifukwa zimatha kupanga chizindikirocho kukhala chokongola kwambiri, cholimba, ndi kusinthika. Njira yolondola yopangira lamination ndi kusankha zinthu kungathe kutsimikizira khalidwe ndi moyo utumiki wa zolembera zomatira. Choncho, opanga kusindikiza ndi ogwiritsa ntchito ayenera kulabadira kusankha njira yoyenera lamination ndi zipangizo, ndikuchita kuwongolera kwamtundu kuti muwonetsetse kuti zilembo zodzimatira zili bwino.
