Njengamanje, izithiyo eziphakeme kanye namafilimu asebenza ngezinto eziningi athuthukiswa kwizinga elisha lobuchwepheshe. Ngokuqondene nefilimu esebenzayo, ngenxa yomsebenzi wayo okhethekile, kungahlangabezana kangcono nokuhlangabezana nezidingo zokupakishwa kwezimpahla, noma kungcono ukuhlangabezana nezidingo zokusebenziseka kwezimpahla, ngakho-ke umphumela ungcono futhi uncintisana kakhulu emakethe. Lapha, sizogxila kumafilimu we-BOPP nama-pet
I-BOPP, noma i-piaxed actientylene, ifilimu epulasitiki esetshenziswa kabanzi ekupakisheni nasekulebula. Ithola inqubo ye-biaxial yokuma empini, ithuthukisa ukucaca kwayo, amandla, nokuphrinta. Yaziwa ngokuguquguquka kwayo okuhlukahlukene, i-BOPP ivame ukusetshenziswa emaphaketheni avumelana nezimo, amalebula, anamathela ompompi, nezinhlelo zokusebenza zokukhanyisela. Inikeza ukubonakala komkhiqizo omuhle kakhulu, ukuqina, futhi iphinde isebenze kabusha, okwenza kube ukukhetha okuthandwayo kwezidingo ezahlukahlukene zokupakisha.
Isilwane, noma i-polyethylene terephthalate, iyi-polymer esetshenziswa kakhulu ye-thermoplastic eyaziwa ngokusebenza okuhlukahlukene nokucaca. Isetshenziswa kakhulu ekukhiqizweni kwamabhodlela epulasitiki eziphuzweni, iziqukathi zokudla, nokupakisha, isilwane sisobala futhi sinezakhiwo ezinhle kakhulu ezibhekene no-oxygen nomswakama. Kuyinto engasindi, ihlala isikhathi eside, futhi iphinde isebenze, okwenza kube ukukhetha okuthandwayo kwezicelo ezahlukahlukene zokupakisha. Ngokwengeziwe, isilwane sisetshenziselwa imicu yezingubo zokugqoka, kanye nasekukhiqizweni kwamafilimu namashidi ngezinhloso ezahlukahlukene.
Umahluko
Izilwane ezifuywayo ze-polyethylene terephthalate, kuyilapho i-BOPP imele i-polypropylene ethambekele. Amafilimu we-Pet and BOPP amafilimu acwebile asetshenziselwa ukupakisha. Zombili izinqumo ezithandwayo zokupakishwa kokudla kanye nezinye izinhlelo zokusebenza, njengamalebula womkhiqizo nezimbobo zokuvikela.
Ngokuphathelene nokwehluka phakathi kwamafilimu we-pet ne-BOPP, umehluko osobala kakhulu yizindleko. Ifilimu lePet livame ukubiza kakhulu kunefilimu le-BOPP ngenxa yamandla alo aphakeme kanye nezakhiwo zalo. Ngenkathi ifilimu ye-BOPP ibiza kakhulu, ayinikezi ukuvikelwa okufanayo noma izithiyo njengefilimu yasekhaya.
Ngaphezu kwezindleko, kunomehluko ekumelaneni nokushisa phakathi kwezinhlobo ezimbili zefilimu. Ifilimu lePet linendawo ephakeme yokuncibilika kunefilimu ye-bopp, ngakho-ke ingamelana namazinga okushisa aphezulu ngaphandle kokukhipha noma ukuncipha. Ifilimu le-BOPP liyamelana kakhulu nomswakama, ngakho-ke ingavikela imikhiqizo ezwela umswakama.
Mayelana nezakhiwo ze-Optical of Pet and BOPP Films, ifilimu yePet inokucaciswa okuphakeme kanye ne-gloss, ngenkathi ifilimu ye-BOPP ine-matte. Ifilimu lasePet liwukukhetha okungcono uma ufuna ifilimu enikeza izakhiwo ezinhle kakhulu.
Amafilimu we-Pet and BOPP enziwe kusuka kuma-resin epulasitiki kepha aqukethe izinto ezahlukahlukene. U-PET uhlanganisa i-polyethylene terephthalate, ehlanganisa amamomoli amabili, i-ethylene glycol, ne-terephthalic acid. Le nhlanganisela idala impahla eqinile futhi engasindi engamelana nokushisa, amakhemikhali, kanye nama-solvents. Ngakolunye uhlangothi, ifilimu le-BOPP lenziwa kusuka ku-polypropylene ethambekele e-biaxed, inhlanganisela ye-polypropylene nezinye izinto zokwenziwa. Lokhu okuqukethwe nakho kuqinile futhi kungasindi kepha kungamelana nokushisa namakhemikhali.
Lezi zinto ezimbili zinokufana okuningi ngokwezindawo ezibonakalayo. Zombili zisobala kakhulu futhi zinokucaca okuhle, okwenza balungele izinhlelo zokusebenza ezidinga umbono ocacile wokuqukethwe. Ngaphezu kwalokho, zombili lezi zinto zokwakha ziqinile futhi zivumelana nezimo, zibenze zilungele izinhlelo zokusebenza ezahlukahlukene.
Kodwa-ke, kukhona umehluko omkhulu. UPet uqinile ngaphezu kwefilimu ye-BOPP futhi ungathathi hlangothi kalula ukudiliza noma ukugaxeka. I-PET inendawo ephakeme yokuncibilika futhi imelana kakhulu nemisebe ye-UV. Ngakolunye uhlangothi, ifilimu le-BOPP lihamba kancane futhi lingelulwa futhi lakhiwe ukuze lilingane nezicelo ezahlukahlukene.
ukubeka kafushane
Ekuphetheni, ifilimu le-pet kanye ne-bopp linokungezwani kwalo. Ifilimu lasePet liyifilimu ye-polyethylene terephthalate film, okwenza kube yi-thermoplastic engashisa futhi yenziwe ngaphandle kokulahlekelwa ubuqotho bayo. Inokuqina okuhle kakhulu, izakhiwo ze-Optical, kanye nokumelana kwamakhemikhali, okwenza kube ukukhetha okuhle kwezicelo eziningi. Ifilimu le-BOPP, ngakolunye uhlangothi, ifilimu ye-poyppropylene ethambekele encanyana. Kuyinto engasindi kodwa eqinile eqinile enezindawo ezinhle kakhulu ze-Optical, Mechanical, kanye ne-Thermal. Kuyazuzisa kuzinhlelo zokusebenza lapho kuchazwa khona ukucaca okuphezulu namandla aphakeme.
Lapho ukhetha phakathi kwalawa mafilimu amabili, kubalulekile ukucubungula isicelo. Ifilimu lePet lilungele izinhlelo zokusebenza ezidinga ukuqina okukhulu okubucayi nokuphikiswa kwamakhemikhali. Ifilimu ye-BOPP ilungele izinhlelo zokusebenza ezidinga ukucaca okuphezulu namandla amakhulu.
Siyethemba ukuthi le bhulogi ikusizile ukuthi uqonde kangcono umehluko phakathi kwamafilimu we-pet ne-bopp bese ukhetha eyodwa evumelana nesicelo sakho.
