I-CPP ifilimu ye-polypropylene (PP) ekhiqizwa yi-cast extrusion embonini yepulasitiki. Lolu hlobo lwefilimu luhlukile kwifilimu ye-BOPP (bidirectional polypropylene) futhi luyifilimu engagxilile. Empeleni, amafilimu e-CPP anokuqondiswa okuthile kuphela ohlangothini lwe-longitudinal (MD), ikakhulukazi ngenxa yohlobo lwenqubo. Ngokupholisa okusheshayo kuma-roller abandayo okuphonsa, ukucaca okuhle kakhulu kanye nokuqeda kwakheka kwifilimu.
Izici Eziyinhloko Zefilimu ye-Cpp:
Izindleko eziphansi kanye nomkhiqizo ophezulu uma kuqhathaniswa namanye amafilimu afana ne-LLDPE, i-LDPE, i-HDPE, i-PET, i-PVC; Ukuqina okuphezulu kunefilimu ye-PE; Umswakama omuhle kakhulu kanye nesithiyo sephunga; Isebenza ngezindlela eziningi, ingasetshenziswa njengefilimu eyisisekelo ehlanganisiwe; Ukwenziwa kwensimbi kungenzeka; Njengokupakisha ukudla nezimpahla kanye nokupakisha kwangaphandle, inokubonakaliswa okuhle kakhulu futhi ingenza umkhiqizo usabonakala ngokucacile ngaphansi kwephakheji.
Njengamanje, kunezinhlobonhlobo zemikhiqizo yamafilimu e-CPP. Kuphela lapho amabhizinisi eqhubeka nokuthuthukisa imikhiqizo emisha, evula amasimu amasha ohlelo lokusebenza, ethuthukisa amakhono okulawula ikhwalithi, futhi eqaphela ngempela ukwenziwa ngokwezifiso komkhiqizo kanye nokwehlukaniswa kwawo, lapho engakwazi khona ukunqoba emakethe.
Ifilimu ye-PP iyi-polypropylene ephonswe ngensimbi, eyaziwa nangokuthi ifilimu ye-polypropylene enganwetshiwe, engahlukaniswa ibe yifilimu ejwayelekile ye-CPP (GCPP), ifilimu ye-aluminized CPP (Metalize CPP, MCPP) kanye nefilimu ye-Retort CPP (RCPP) ngokwezindlela ezahlukene zokusetshenziswa.
I-CPP ifilimu enganwetshiwe, engagxilile ekhishwe ngokuncibilikisa okuncibilikisiwe. Uma iqhathaniswa nefilimu evuvukile, ibonakala ngesivinini sokukhiqiza esisheshayo, umkhiqizo ophezulu, kanye nokucaca okuhle kwefilimu, ukucwebezela, kanye nokufana kobukhulu. Ngesikhathi esifanayo, ngoba iyifilimu ekhishwe ngokuyisicaba, izinqubo zokulandelela ezifana nokuphrinta nokunamathisela zilula kakhulu, ngakho-ke zisetshenziswa kabanzi ekupakisheni izindwangu, izimbali, ukudla kanye nezidingo zansuku zonke.
1. Ama-Rolls nama-Pouches aqoshiwe
Ukucaca okuphezulu,Incazelo ephezulu (i-cellulite encane) ukuze kube nomphumela omuhle wefasitela. Isetshenziselwa ukupakisha okusobala njengezingubo.
Ukushelela okuphezulu, ukufuduka okuphansi, ukugcinwa okuphezulu kwe-corona, gwema ukunqwabelana kwama-precipitate enqubweni yangemva kokucubungula, wandise impilo yeshelufu, esetshenziswa ekupakisheni i-sachet, ifilimu ehlanganisiwe engenaso isinyibilikisi, njll.
Ukuvalwa kokushisa okuphansi kakhulu, izinga lokushisa lokuqala lokuvala ukushisa lingaphansi kuka-100°C, elisetshenziswa ekupakisheni kwemithi, emigqeni yokupakisha esheshayo.
Imisebenzi Yefilimu Ye-Cpp Ekupakisheni Okuguquguqukayo
5. Ifilimu yethawula lephepha
Ifilimu yokugoqa ephezulu, ethambile kakhulu (17μ), ngenxa yokuntuleka kokuqina ngemva kokuncipha kwe-CPP ayikwazi ukuzivumelanisa nomugqa wokupakisha wezicubu osheshayo, iningi lefilimu yokugoqa lithathelwa indawo yi-BOPP yokuvala ukushisa enamacala amabili, kodwa ifilimu yokugoqa ukushisa ye-BOPP nayo inezinkinga zomphumela we-notch, ukudabuka okulula, kanye nokumelana okungekuhle komthelela.
2. I-substrate yefilimu eyenziwe nge-aluminium
Ukuqina okuphezulu, kunciphisa umugqa wokufaka ongenalutho, futhi kuthuthukise ikhwalithi yemikhiqizo eyenziwe nge-aluminium; Ukunamathela okuphezulu kwesendlalelo esenziwe nge-aluminium, kufika ku-2N/15mm noma ngaphezulu, ukuze kuhlangatshezwane nezidingo zokupakisha okukhulu.
Ukuvalwa kokushisa okuphansi kakhulu ukuze kuhlangatshezwane nezidingo zokupakisha okuzenzakalelayo okusheshayo.
I-coefficient ephansi yokungqubuzana, ithuthukisa ukuvulwa, ivumelane nezidingo zokwenza izikhwama ngesivinini esikhulu kanye nokupakisha.
Ukugcinwa kokucindezeleka okuphezulu kokumanzisa okuphezulu kwesendlalelo se-aluminium ukuze kwandiswe impilo yeshelufu ye-CPP eyenziwe nge-aluminium.
3, Ifilimu Ephendulayo
Ifilimu yokuphendula eshisa kakhulu (121-135°C, imizuzu engama-30), ehlanganiswe namafilimu okuvimbela njenge-PET, i-PA, i-aluminium foil, njll., isetshenziselwa ukupakisha imikhiqizo edinga ukusabela okushisayo okuphezulu kanye nokubulala amagciwane, njengenyama, ubhontshisi, imikhiqizo yezolimo kanye nezinto zokwelapha. Izinkomba zokusebenza ezibalulekile zefilimu yokupheka ye-CPP amandla okuvala ukushisa, amandla okushaya, amandla ahlanganisiwe, njll., ikakhulukazi ukugcinwa kwezinkomba ezingenhla ngemva kokupheka. Ukuzinza kwekhwalithi yefilimu yokupheka eshisa kakhulu kuyisici esiyinhloko esivimbela ukusetshenziswa kwamakhasimende angaphansi komfula.
4. Imikhiqizo Yomsindo Nokubukwayo Namafilimu E-albhamu
Ukucaca okuphezulu, incazelo ephezulu, ukucwebezela okuphezulu kanye nokumelana nokuklwebheka
6. Ifilimu Yelebula Nefilimu Yetheyiphu
Ukuqina okuphezulu, ukucindezeleka okuphezulu kokumanzisa ubuso, ukusika kalula nge-die, kungakhiqiza amafilimu anombala asobala, amhlophe, amaphepha noma amanye anombala ngokwesidingo, asetshenziselwa kakhulu amalebula okunamathela, imikhiqizo noma izimpawu zezindiza, izitika zesinqe zabantu abadala, amanabukeni ezingane kwesobunxele nakwesokudla, njll.;
7. Ifilimu Yamafindo
Thuthukisa ukugoba nokuqina, ikakhulukazi ukugoba kwe-kink ngemva kokunqoba i-aluminium.
8. Ifilimu enganyakazi
Ifilimu ye-CPP antistatic ingahlukaniswa ibe yifilimu ye-hygroscopic antistatic kanye nefilimu ye-permanent antistatic, efanelekile ekupakishweni kokudla nempuphu yemithi kanye nezingxenye ezahlukahlukene ze-elekthronikhi.
9. Ifilimu yokulwa nenkungu
Umphumela wokuvikela inkungu ebandayo ehlala isikhathi eside kanye nomphumela wokuvikela inkungu eshisayo, osetshenziselwa izithelo ezintsha, imifino, amasaladi, amakhowe adliwayo kanye nokunye ukupakisha, ukubona kahle okuqukethwe lapho kufakwe efrijini, futhi kuvimbele ukudla ukuthi kungonakali futhi kubole.
10. Ifilimu Ehlanganisiwe Yesivikelo Esiphezulu
Ifilimu yokukhipha ndawonye: Ifilimu yokuvimba okuphezulu ekhiqizwa yi-co-extrusion ye-PP enokusebenza okuhle kokuvimba amanzi kanye ne-PA, EVOH nezinye izinto ezinokusebenza kahle kokuvimbela umoya-mpilo isetshenziswa kabanzi emikhiqizweni eqandisiwe yenyama kanye nokupakisha ukudla kwenyama okuphekiwe; Inokumelana okuhle namafutha kanye nokumelana okuncibilikayo kwezinto eziphilayo, futhi ingasetshenziswa kabanzi ekupakisheni uwoyela odliwayo, ukudla okulula, imikhiqizo yobisi, kanye nemikhiqizo yehadiwe yokulwa nokugqwala; Inokumelana okuhle kwamanzi kanye nomswakama, futhi ingasetshenziswa ekupakisheni okumanzi njengewayini kanye nesoso yesoya; Ifilimu embozwe nge-PVA eguquliwe, enikeza i-CPP izakhiwo zokuvimbela igesi ephezulu.
Ifilimu Ehlanganisiwe Eyengeziwe Ye-11.Pe
Ifilimu ye-CPP ekhiqizwa ngokuguqulwa ingakhishwa ngqo nge-LDPE nezinye izinto zefilimu, okungagcini nje ngokuqinisekisa ukushesha kwenhlanganisela ye-extrusion, kodwa futhi kunciphisa izindleko ze-lamination.
Ukusebenzisa i-PP njengengqimba yokunamathela kanye ne-PE ukukhipha ifilimu ehlanganisiwe ne-PP elastomer ukwakha isakhiwo somkhiqizo we-PP/PE noma we-PE/PP/PE, esingagcina izici zamandla aphezulu kanye nokucaca okuhle kwe-CPP, futhi sisebenzise izici zokuguquguquka kwe-PE, ukumelana nokushisa okuphansi kanye nokushisa okuphansi kokuvala ukushisa, okusiza ekunciphiseni ukujiya nokunciphisa izindleko zokupakisha zamakhasimende okugcina, futhi kusetshenziselwa ukupakisha ukudla, ukupakisha izicubu nezinye izinjongo.
12.ifilimu yokuvala elula ukuyivula
Ifilimu yokudabuka eqondile elula, ifilimu ye-CPP ekhiqizwe yi-PP eguquliwe kanye nenqubo yokukhiqiza ekhethekile inokusebenza kahle kokudabuka eqondile okulula, futhi ihlanganiswe nezinye izinto zokwakha ukwenza izikhwama zokudabuka eziqondile ezilula, okulula kubathengi ukuzisebenzisa.
Ifilimu elula yokuhluza, ehlukaniswe izinhlobo ezimbili zokupheka ezishisayo nezingapheki, ngokuguqulwa kwesendlalelo sokuvala ukushisa i-PP ukuze kukhiqizwe ifilimu elula yokuhluza i-CPP, kanye ne-BOPP, i-BOPET, i-BOPA, i-aluminium foil nezinye izinto zokupakisha zingahlanganiswa zibe ukupakishwa okulula kokuhluza, ngemva kokuvalwa kokushisa, ingadonswa ngqo kusuka onqenqemeni lokuvala ukushisa, okwenza kube lula kakhulu ukusetshenziswa kwabathengi.
13. Ifilimu ye-Cpp Ebolayo
Ifilimu yokonakala kwe-CPP eyenziwe ngokufaka i-photosensitizer noma i-masterbatch ebolayo ku-PP ingabola ibe yizinto ezingaphili futhi imuncwe yinhlabathi ngaphansi kwezimo zemvelo cishe izinyanga eziyi-7 kuya kweziyi-12, okuthuthukisa ukuzivumelanisa nokufakwa kwepulasitiki nokuvikelwa kwemvelo.
Ifilimu ye-Cpp engabonakali engu-14. Ukuvimba i-UV
