1. Ifilimu yokuvikela ye-PE, yiziphi izimo okufanele ihlangabezane nazo ukuze ibhekwe njengelungile?

Uhlobo luni lwefilimu yokuvikela ye-PE olubhekwa njengoluhle? Lo mbuzo, ngokombono oyisisekelo, ubhekisela ezidingweni eziyisisekelo kanye nemibandela okufanele lolu hlobo lwefilimu yokuvikela luhlangabezane nayo ukuze lusetshenziswe kahle. Ngakho-ke, impendulo ithi:

Isimo 1: Inhlaka yefilimu evikelayo ifanelekile, kulula ukuyidabula nokuyinamathelisa, futhi ngeke kube khona insalela.

Isimo 2: Ngemva kokushintsha kwesikhathi, ukwanda kwamandla okuxebuka kuba kuncane.

Isimo 3: Ngisho noma ibekwe elangeni, ingaqinisekisa impilo yokusebenza kusukela ezinyangeni eziyisithupha kuya onyakeni owodwa.

Isimo 4: Ngisho noma igcinwe isikhathi esingaphezu konyaka owodwa, ikhwalithi yayo ngeke ishintshe.

Isimo 5: Ngeke ingcolise imvelo, ngeke ibole, futhi ngeke ithambekele ekushintsheni kwamakhemikhali. Ngaphezu kwalokho, izakhiwo zemishini nazo zingagcinwa kahle.

2. Yisiphi isici esiyinhloko sefilimu yokuvikela ye-PE? Ngaphezu kwalokho, ingabe ikhona ifilimu yokuvikela ekhethekile yensimbi engagqwali ye-PE?

Ingaphakathi eligoqayo eliphakathi kwefilimu yokuvikela ye-PE lenziwe nge-PE, futhi kunezinhlobo ezimbili zamapayipi amasha namapayipi enziwe ngezinto eziphinde zasetshenziswa. Ngakho-ke, awafani ngokwentengo. Embuzweni 2, impendulo inguyebo, okungukuthi, kwifilimu yokuvikela ye-PE, kunefilimu yokuvikela ekhethekile yensimbi engagqwali ye-PE.

3. Ngemva kokuba ifilimu yokuvikela ye-PE inamathiselwe, kuvela amabala amhlophe efilimu. Iyini imbangela?

Ifilimu yokuvikela ye-PE, uma kuvela amabala amhlophe ngemva kokufakwa kweglue, khona-ke, isizathu esiqondile ukuba khona kwezinhlayiya zeglue, noma izinga lokushisa lokubhaka elingalingani, ngaphezu kwalokho, kungenzeka futhi ukuthi kunenkinga ngekhanda lokumboza. Ngakho-ke, kuyadingeka ukuphenya ngamunye ngamunye ukuthola isizathu sangempela sokuyixazulula ngempumelelo. Ngaphezu kwalokho, le nkinga iyinkinga yekhwalithi yomkhiqizo futhi kufanele inakwe.

1. Amaqoqo ahlukene kayinki ayengezwa ekuhlolweni kosayizi wezinhlayiya futhi alawulwa ngokuqinile, ikakhulukazi lawo lapho ubukhulu bezinhlayiya kanye nosayizi wezinhlayiya zohlobo lweyinki oluphelele kanye nosayizi wezinhlayiya kuhlakazeke ngaphandle kwesikali esijwayelekile kungakhethwanga; khetha umhlinzeki omuhle kakhulu nozinzile.

2. Sebenzisa ingcina ekhethekile yefilimu yokuvikela kagesi. Ingcina ekhethekile yenhlanganisela yefilimu yokuvikela kagesi inokucindezeleka okuphansi kobuso, futhi ukumbozwa kwayo kanye nomphumela wokusabalala ebusweni bengqimba yeglue kungcono kakhulu kunokwezinhlayiya ezisetshenziswa kabanzi. Kulula kakhulu ukulawula ukulevelishwa koketshezi lweglue ngokusebenzisa ingcina yeglue, futhi inesimo esihle sokumboza. Ngokuphathelene nezimo zokumboza ingcina kuphela, ukusetshenziswa kweglue ye-electronic kungasusa amathuba okuba namabala amhlophe.

3. Kukhona ubudlelwano obuthile bokufanisa phakathi kwe-viscosity yeglue kanye nenani lemigqa ye-screen roll. Uma isikhawu sokufanisa sikhulu kakhulu, isimo sokumboza kweglue sizokonakala, futhi ukuvela “kwamabala amhlophe” kubaluleke kakhulu.

4. Khetha indlela yokunamathisela ifilimu evikelayo kagesi. Ubuchwepheshe bokunamathisela obusetshenziswa kakhulu ukunamathisela ifilimu yokunyathelisa (ubuso beyinki). Lapha, kusetshenziswa indlela ekhethekile yokunamathisela ukuze kugwenywe umbuzo wokungena okungalingani kwengqimba yeyinki yi-ethyl ester futhi kugwenywe inkinga yokungena okungalingani kwengqimba yeyinki yi-ethyl ester. , Ngesikhathi esifanayo, inhlaka ehlanganisiwe ingamboza ubuso bengqimba yeglue ngokwanele nangokulinganayo, okungasusa amabala amhlophe kahle kakhulu. Kodwa lobu buchwepheshe bunemikhawulo yabo emikhulu. Okokuqala, bukhawulelwe kuphela kunhlanganisela ye-VMPET, kuyilapho amanye amafilimu okuvikela kagesi ezokwelulwa futhi aguquguquke ngaphansi komphumela wokucindezeleka ngaphansi kwethonya lokushisa kuhhavini; okwesibili, azodela amandla athile okuhluba. .

5. Izinkampani zokupakisha eziguquguqukayo kumele zilandele iziqondiso zokuhlanza ezivamile ze-coating roller futhi zibe yingcweti ezindleleni zokuhlanza ezinembile ze-coating roller. Lapho kukhishwa ifilimu yokunyathelisa emhlophe noma ekhanyayo ngemuva, kufanele kunakwe amaphuzu amabili. Okokuqala, i-doctor blade, i-coating roller, kanye ne-flatening roller kufanele kuhlanzwe ngokuphelele ngaphambi kokukhiqizwa.

6. I-glue kufanele yome ngokuphelele. Ngenxa yokuthi isici sokuvimbela se-aluminium plating singcono, uma ukubopha kwifilimu ehlanganisiwe kungomi ngokuphelele, khona-ke ngemva kokuba ifilimu ehlanganisiwe ingene egumbini lokuvuthwa, inani elikhulu le-solvent esele lidinga ukukhishwa ngokushesha, futhi ngaphansi kwesithiyo sefilimu evikelayo kagesi, kuzomele yakhe amabhamuza omhwamuko. Kungabonisa ngisho nesimo sokuthi azikho izindawo ezimhlophe lapho umshini uvaliwe, kodwa izindawo ezimhlophe ziyavela ngemva kokupholisa.
