"I-polypropylene yenziwe nge-polymerization yegesi ngemuva kokuqhekeka kwezinga lokushisa eliphezulu kwe-petroleum ngaphansi kwesenzo se-catalysts, ngokusho kwezindlela ezihlukene zokucubungula ifilimu zingatholakala kumafilimu ahlukene okusebenza, ngokuvamile asetshenziswa ngokuyinhloko i-BOPP yenhloso evamile, i-matte BOPP, ifilimu yeparele, I-BOPP evalwe ngokushisisa, i-CPP eyi-cast, i-Blow Molding IPP, njll. Lesi sihloko sihlaziya ukusebenza kokuphrinta nokwenza izikhwama kwalezi zinhlobo zamafilimu ngokuningiliziwe.
1, Ifilimu ye-BOPP yenhloso evamile
Ifilimu ye-BOPP icutshungulwa ukuze ingxenye ye-amorphous noma ingxenye yefilimu ye-crystalline yelulwe ku-longitudinal kanye nezikhombisi-ndlela eziguquguqukayo ngaphezu kwendawo yokuthambisa, ukuze indawo yefilimu ikhule, ukushuba kuncishiswe, futhi ukucwebezela nokucaca kuthuthukiswe kakhulu.Ngesikhathi esifanayo, amandla emishini, ukuqina komoya, umgoqo womswakama kanye nokumelana nokubanda kuthuthukiswa kakhulu ngenxa yokuma kwe-molecule enwetshiwe.
Izici zefilimu ye-BOPP:
Amandla aphezulu aqinile, i-modulus ephezulu yokunwebeka, kodwa amandla okudabula aphansi;ukuqina okuhle, ukunwebeka okuvelele kanye nokumelana nokugoba ukusebenza kokukhathala;ukumelana nokushisa nokubanda kuphakeme, ukusetshenziswa kwezinga lokushisa kufika ku-120 ℃, ukumelana nokubanda kwe-BOPP nakho kuphakeme kunefilimu ye-PP evamile;isicwebezelisi esiphezulu, ukukhanya okuhle, okulungele izinhlobonhlobo zezinto zokupakisha;Ukuqina kwamakhemikhali e-BOPP kuhle, ngaphezu kwama-acids aqinile, njenge-fuming sulfuric acid, i-nitric acid inomphumela olimazayo kuyo Ngaphezu kwalokho, ayincibiliki kwezinye izinyibilikisi, futhi amanye ama-hydrocarbon kuphela anomphumela wokuvuvukala kuwo;ukumelana kwamanzi okuhle kakhulu, enye yezinto ezihamba phambili zokumelana nomswakama nomswakama, izinga lokumuncwa kwamanzi <0.01%;ukuphrinta okungalungile, ngakho-ke indawo engaphezulu kufanele iphathwe nge-corona ngaphambi kokuphrinta, umphumela omuhle wokuphrinta ngemuva kokucubungula;ugesi we-static ophezulu, i-resin esetshenziselwa ukukhiqizwa kwefilimu idinga ukungezwa ku-ejenti ye-antistatic.
2, Matte BOPP
Isendlalelo esingaphezulu se-matte BOPP siklanywe njengesendlalelo se-matte, esenza ukubukeka kokuthungwa kufane nephepha futhi kukhululeke ekuthinteni.Isendlalelo se-matte ebusweni ngokuvamile asisetshenziselwa ukuvalwa kokushisa, ngenxa yokuba khona kwesendlalelo se-matte, uma kuqhathaniswa nenhloso evamile ye-BOPP, inezici ezilandelayo: ungqimba lwe-matte ebusweni lungadlala indima ye-shading, i-gloss ebusweni nayo iyancipha kakhulu;ungqimba lwe-matte lungasetshenziselwa ukuvala uphawu lokushisa uma kunesidingo;ungqimba olungaphezulu lwe-matte lubushelelezi futhi luhle, ngoba ingaphezulu lenziwe roughed nge-anti-adhesive, imiqulu yefilimu akulula ukunamathela;Ifilimu ye-matte amandla aqinile aphansi kancane kunefilimu yenhloso evamile, ukuzinza okushisayo kubizwa nangokuthi i-BOPP evamile kubi kakhulu.
3, ifilimu ye-Pearlescent
Ifilimu ye-pearlescent yenziwe nge-PP, i-CaCO3, i-pearlescent pigment kanye ne-rubber hood modifier iyengezwa futhi ixutshwe nokunwebeka kwe-bi-directional.Njengoba ama-molecule e-PP resin enwetshwa ngesikhathi senqubo yokwelula i-biaxial, futhi izinhlayiya ze-CaCO3 zeluliwe zihlukana komunye nomunye, ngaleyo ndlela zenze ama-bubbles we-pore, ngakho-ke ifilimu ye-pearlescent ifilimu yegwebu elincane elinobukhulu obungu-0.7g/cm³.
I-molecule ye-PP ilahlekelwa ukuvaleka kwayo kokushisa ngemva kokuma kwe-biaxial, kodwa isenokuvalwa okuthile kokushisa njengenjoloba nezinye izilungisi, kodwa amandla ophawu lokushisa aphansi kakhulu futhi kulula ukuwadabula, okuvame ukusetshenziswa ekufakweni kuka-ayisikhilimu, i-popsicle, njll.
4. Ifilimu ye-BOPP yokuvala ukushisa
Ifilimu enezinhlangothi ezimbili evalwe ngokushisisa:
Le filimu iyisakhiwo se-ABC, izinhlangothi ezingu-A no-C zosendlalelo sophawu lokushisa.Isetshenziswa kakhulu njengezinto zokupakisha zokudla, izindwangu, imikhiqizo yomsindo nevidiyo, njll.
Ifilimu yophawu lokushisa oluhlangothini olulodwa:
Lolu hlobo lwefilimu luyisakhiwo se-ABB, nesingqimba esingu-A njengongqimba oluvala ukushisa.Ngemuva kokuphrinta amaphethini ohlangothini lwe-B, i-laminated nge-PE, BOPP ne-aluminium foil ukwenza izikhwama, ezisetshenziswa njengezinto zokupakisha ezisezingeni eliphezulu zokudla, iziphuzo, itiye, njll.
5, Ifilimu ye-CPP ebambezeleke ngokugeleza
Ifilimu ye-CPP ye-polypropylene ye-Cast ifilimu ye-polypropylene enganwebeki, engaqondile.
Ifilimu ye-CPP ibonakala ngokusobala okuphezulu, ukukhanya okuhle, ukumelana nokushisa okuphezulu okuhle, izinga elithile lokuguquguquka ngaphandle kokulahlekelwa ukuguquguquka, izakhiwo ezinhle zokuvala ukushisa.I-Homopolymer CPP inohlu oluncane lokushisa lokuvalwa kokushisa kanye nokuqina okuphezulu, okuyenza ifanelekele ukusetshenziswa njengefilimu yokupakisha enesendlalelo esisodwa.
I-Co-polymer CPP inomsebenzi olinganiselayo futhi ifaneleka njengongqimba lwangaphakathi lwefilimu eyinhlanganisela.Njengamanje, i-CPP ejwayelekile i-co-extruded CPP, ingasebenzisa ngokugcwele izici ezihlukahlukene ze-polypropylene yenhlanganisela, okwenza ukusebenza kwe-CPP kuphelele.
6. Ifilimu ye-IPP eshaywayo
Ifilimu eshaywa yi-IPP ngokuvamile ikhiqizwa ngendlela yokushaya phansi, i-PP ikhishwa futhi iqhunyiswe emlonyeni wendandatho, ngokushesha ngemva kokupholisa kokuqala ngendandatho yomoya, emise ukupholisa okuphuthumayo kwamanzi, omisiwe futhi agingqelwe, umkhiqizo ophelile uyifilimu yesilinda, okungabuye kusikwe kube ifilimu yeshidi.I-IPP eshaywayo inokucaca okuhle, ukuqina okuhle kanye nokwenza izikhwama okulula, kodwa ukufana kwayo kogqinsi kubi futhi ukucaba kwefilimu akwanele.
