Ngemuva kokubukezwa kwamafilimu e-BOPP, ingabe unokungaqondi kahle lokhu okubalulekile okutholakala yonke indawo? Kule bhulogi, sizojulisa ukuqonda kwethu ebuhleni nasebubini bayo, ngaleyo ndlela siqondise kangcono izidingo zabathengi.
Yini i-BOPP Film
Ifilimu ye- Biaxially Oriented Polypropylene (BOPP) isiguqule imboni yokupakisha kusukela yethulwa ngawo-1970s. Lokhu kwaziswa okuqanjiwe, okweluliwe kokubili ngokomshini nangokwenziwa ngesandla kusetshenziswa amasu okuqondisa okuphambanayo, kunikeza inhlanganisela eyingqayizivele yezakhiwo ezikwenze kwadingeka kakhulu ekusetshenzisweni okuhlukahlukene.
Izici ezibalulekile ze-BOPP
engenambala futhi engenaphunga Imvelo
okungewona ubuthi Ukwakheka
okulinganiselwe Ukuqina kanye nokuqina
ohlaba umxhwele Ukumelana nomthelela
aphezulu Amandla okuqina (amanani ajwayelekile asukela ku-130-300 MPa)
ngale okuyingqayizivele Ukubonisa (kufika ku-90% wokudlulisa ukukhanya)
Lezi zakhiwo zibeke i-BOPP njengento eguquguqukayo kuzo zonke izimboni eziningi, kusukela ekufakweni kokudla kuya ekufakweni kwezindwangu.
Izinzuzo ze-BOPP Film
Izakhiwo Zomzimba
I-BOPP ihamba phambili ngamandla nokuqina, inamandla aqinile angafinyelela ku-300 MPa endleleni yomshini. Ukubukeka kwayo kucace njengekristalu, namazinga okudlulisa ukukhanya afika ku-90%, kuthuthukisa ukubonakala komkhiqizo emashalofini esitolo. Ukuzinza kohlangothi lwefilimu kuqinisekisa ukusebenza okungaguquguquki kuzo zonke izinhlelo zokusebenza ezihlukahlukene, namazinga avamile okushwabana angaphansi kuka-4% ku-130°C.
Ukumelana nama-punctures kanye nokuqhekeka okuguquguqukayo kwenza i-BOPP ilungele ukupakishwa kokuvikela. Isibonelo, ifilimu ye-BOPP yama-micron angu-20 ingamelana nokufika ku-130 g/25 μm ekuhlolweni komthelela we-dart, okubonisa ukuqina kwayo ezinhlelweni zokusebenza zomhlaba wangempela.
Chemical Properties
I-BOPP isebenza njengesithiyo esesabekayo ngokumelene nomswakama, ukungcola, namakhemikhali ayingozi. Izinga layo lokudlulisa umhwamuko wamanzi (WVTR) lingaba phansi njengo-4-5 g/m²/ngosuku ku-38°C kanye no-90% womswakama ohlobene, okuyenza ibe ukukhetha okuhle kakhulu emikhiqizweni engezwani nomswakama.
Ukumelana nowoyela namafutha efilimu, ngamavelu ajwayelekile angaphezu kuka-7 esikalini sokuhlola sekhithi, kunwebisa ukusebenza kwayo. Lezi zakhiwo zenza i-BOPP ibe yisinqumo esihle kakhulu sokupakishwa kokudla kanye nokusetshenziswa kwezimboni, lapho ukuvikelwa komkhiqizo kubaluleke kakhulu.
Izinzuzo Zemvelo
Emhlabeni wanamuhla oqaphela imvelo, i-BOPP ikhanya ngemininingwane yayo yezemvelo:
Ukuphinda kusetshenziswe kabusha : I-BOPP iwela ngaphansi kwekhodi yokugaya kabusha engu-#5 (PP), iyenze ikwazi ukuphinda igaywe kabusha.
Isisindo Esilula : Ukuminyana okujwayelekile cishe okungu-0.90-0.92 g/cm³ kunikela ekukhiqizweni kwezinto zokuhamba.
Ukukhiqizwa okuwonga amandla : Inqubo yokukhiqiza idla amandla amancane uma iqhathaniswa nezinye izinto ezisetshenziswayo.
Ucwaningo lokuhlola umjikelezo wempilo olwenziwa yi-European Polypropylene Film Manufacturers Association luthole ukuthi amafilimu e-BOPP anekhabhoni ephansi ngo-40% uma kuqhathaniswa namafilimu e-PET alinganayo.
Izinzuzo Zezomnotho
I-BOPP inikeza izinzuzo zezindleko ezibalulekile ngenxa yesivuno sayo esiphezulu. Ukuminyana kwayo okungaba ngu-0.90-0.92 g/cm³ kubangela ifilimu eyengeziwe ngeyunithi ngayinye yesisindo uma kuqhathaniswa nezinye ezifana ne-polyester (ukuminyana ~1.4 g/cm³). Lokhu kuhumushela ekongeni izindleko kukho kokubili ukusetshenziswa kwezinto ezibonakalayo nezokuthutha.
Ukwamukelwa komhlaba wonke kusiza ukuhwebelana kwamazwe ngamazwe nokuthumela ngemikhumbi kube lula. Ngokwemibiko yezimboni, isifunda sase-Asia-Pacific siphethe imakethe ye-BOPP, sibalwa ngaphezu kwama-60% wamandla okukhiqiza emhlabeni jikelele.
Ukuguquguquka
Ukusebenza ngezindlela ezihlukahlukene kwe-BOPP kubonakala ohlwini lwayo lokuqedwa okutholakalayo:

Ububi befilimu yeBOPP
Izinkinga zokuvala
Izakhiwo zokuvala ezingezinhle ze-BOPP zingaba yinkinga kwezinye izinhlelo zokusebenza zokupakisha. Amandla okuvalwa kokushisa ajwayelekile asukela ku-200-400 g/25 mm, aphansi uma kuqhathaniswa namanye amafilimu. Lo mkhawulo uvamise ukudinga ukwelashwa okwengeziwe noma izimbotshana ukuze kuthuthukiswe ukuvaleleka, okungase kukhuphule izindleko zokukhiqiza.
Ukukhathazeka Kwezamandla Okuphezulu
Amandla aphansi angaphezulu (imvamisa engu-29-31 mN/m) aholela ezinseleleni zokunamathela kukayinki. Lokhu kubangela ikhwalithi yokuphrinta okungenzeka ibe buthakathaka, okwenza kudingeke ukwelashwa kwendawo ngaphambi kwezinqubo zokuphrinta. Ukwelashwa kweCorona kungakhuphula amandla angaphezulu afike ku-38-42 mN/m, kodwa lo mphumela uyancipha ngokuhamba kwesikhathi.
I-Crystalline Nature
se-BOPP Isakhiwo se-crystalline ephezulu (imvamisa engu-60-70% ubucwebe bekristalu) bungabangela:
Lezi zinkinga zingase zithinte ukubukeka nokusebenza kwefilimu ezinhlelweni ezithile, ikakhulukazi lapho ukucaca okubonakalayo kubalulekile.
I-Static Electricity
Ukukhiqizwa kwesivinini esikhulu kuvame ukukhiqiza ugesi omile kumafilimu e-BOPP, okunamandla okumelana nendawo okufika ku-10¹⁶ Ω/sq. Lokhu kwenza kudingeke ukuthi kusetshenziswe izinqubo zokususa ezimile ngesikhathi sokukhiqiza, kwenezela inkimbinkimbi nezindleko emigqeni yokukhiqiza.
