1. UniversalIfilimu ye-BOPP
Ifilimu ye-BOPP iyinqubo lapho amafilimu e-amorphous noma ayingxenye yekristalu enwetshwa aqonde phezulu futhi avundlile ngaphezu kwendawo yokuthambisa ngesikhathi sokucubungula, okuholela ekwandeni kwendawo engaphezulu, ukuncipha kogqinsi, kanye nokuthuthukiswa okuphawulekayo kokucwebezela nokuba sobala.Ngesikhathi esifanayo, ngenxa yokuma kwe-molecule enwebekayo, amandla awo emishini, ukungangeni komoya, ukumelana nomswakama, nokumelana nokubanda kuye kwathuthukiswa kakhulu.
Izici zefilimu ye-BOPP:
Amandla aphezulu aqinile kanye ne-elastic modulus, kodwa amandla okudabula aphansi;Ukuqina okuhle, ukunwebeka okuvelele kanye nokugoba ukumelana nokukhathala;Ukushisa okuphezulu nokumelana nokubanda, nokushisa kokusetshenziswa okufika ku-120℃.I-BOPP futhi inokumelana okubandayo okuphezulu kunamafilimu ajwayelekile e-PP;Isicwebezelisi esiphezulu nokucaca okuhle, kulungele ukusetshenziswa njengezinto ezihlukahlukene zokupakisha;I-BOPP inokusimama okuhle kwamakhemikhali.Ngaphandle kwama-acids aqinile, njenge-Oleum ne-nitric acid, ayincibiliki kwezinye izinyibilikisi, futhi amanye kuphela ama-hydrocarbon anomphumela wokuvuvukala kuwo;Inokumelana namanzi okuhle kakhulu futhi ingenye yezinto ezihamba phambili zokumelana nomswakama nomswakama, ngezinga lokumunca amanzi elingaphansi kuka-0.01%;Ngenxa yokungaphrinteki kahle, ukwelashwa kwe-corona engaphezulu kufanele kwenziwe ngaphambi kokunyathelisa ukuze kuzuzwe imiphumela emihle yokunyathelisa;Ugesi omile ophakeme, i-agent ye-Antistatic izokwengezwa ku-resin esetshenziselwa ukukhiqizwa kwefilimu.
2. I-Matte BOPP
Idizayini engaphezulu ye-matte BOPP iyisendlalelo se-matte, okwenza ukubukeka kuzizwe njengephepha futhi kukhululekile ukuthinta.Indawo yokushabalala ngokuvamile ayisetshenziselwa ukuvala ukushisa.Ngenxa yokuba khona kwesendlalelo sokuqothula, uma kuqhathaniswa ne-BOPP evamile, inezici ezilandelayo: indawo yokuqothula ingadlala indima yomthunzi, futhi ukucwebezela kwendawo nakho kuyancipha kakhulu;Uma kunesidingo, isendlalelo sokuqothula singasetshenziswa njengesembozo esishisayo;Indawo yokuqothulwa inobushelelezi obuhle, njengoba i-surface coarsening ine-anti adhesion futhi ifilimu roll akulula ukunamathela;Amandla aqinile wefilimu yokushabalala angaphansi kancane kunalawo efilimu evamile, futhi ukuzinza kwe-thermal nakho kubi kakhulu kunaleyo ye-BOPP evamile.
Ifilimu ye-Pearlescent yenziwe nge-PP njengento eluhlaza, yengezwe nge-CaCO3, i-pearlescent pigment, ne-ejenti eguquliwe yenjoloba, exutshwe futhi yelulwe nge-biaxially.Ngenxa yokwelula kwama-molecule e-PP resin ngesikhathi senqubo yokwelula i-biaxial, ibanga eliphakathi kwezinhlayiya ze-CaCO3 liyanwetshwa, okuholela ekwakhekeni kwamabhamuza anezimbotshana.Ngakho-ke, ifilimu ye-pearlescent iyifilimu yegwebu elincane elinobukhulu obungu-0.7g/cm ³ Kwesobunxele nakwesokudla.
Ama-molecule e-PP alahlekelwa izici zawo zokuvala ukushisa ngemva kokuma kwe-biaxial, kodwa njengezishintshi ezifana nerabha, asenazo izici ezithile zokuvala ukushisa.Kodwa-ke, amandla okuvala ukushisa aphansi futhi kulula ukuwaqeda, okwenza ajwayele ukusetshenziselwa ukupakisha u-ayisikhilimu, ama-popsicles, neminye imikhiqizo.
4. Ukushisa okuvalwe ngefilimu ye-BOPP
Ifilimu yokuvala ukushisa enezinhlangothi ezimbili:
Le filimu ezacile inesakhiwo se-ABC, futhi zombili izindawo eziwu-A no-C zivaliwe ngokushisa.Isetshenziswa kakhulu njengezinto zokupakisha zokudla, izindwangu, imikhiqizo yomsindo nevidiyo, njll.
Ifilimu yokuvala ukushisa ehlangothini olulodwa:
Le filimu ezacile inesakhiwo se-ABB, ungqimba luka-A luwungqimba oluvala ukushisa.Ngemva kokunyathelisa iphethini ohlangothini lwe-B, ihlanganiswa ne-PE, BOPP, ne-aluminium foil ukuze kwakhiwe isikhwama, esisetshenziswa njengezinto zokupakisha eziphezulu zokudla, iziphuzo, itiye, nezinye izinjongo.
5. Ifilimu ye-CPP yokusakaza
Ifilimu ye-CPP ye-polypropylene ye-Cast ifilimu ye-polypropylene enganwebeki, engaqondile.
Izici zefilimu ye-CPP ziwukucaca okuphezulu, ukucaba okuhle, ukumelana okuhle kwezinga lokushisa eliphezulu, izinga elithile lokuqina ngaphandle kokulahlekelwa ukuguquguquka, nokuvala ukushisa okuhle.I-Homopolymer CPP inebanga lokushisa elincane lokuvalwa kokushisa nokuqina okuphezulu, okuyenza ifanelekele ukusetshenziswa njengefilimu yokupakisha enesendlalelo esisodwa,
Ukusebenza kwe-CPP eyenziwe nge-copolymerized kuyalinganisela futhi kufanelekile njengempahla yongqimba yangaphakathi yolwelwesi oluyinhlanganisela.Njengamanje, ngokuvamile i-co extruded CPP, engasebenzisa ngokugcwele izici ze-polypropylene ehlukahlukene ukuze ihlanganiswe, yenze ukusebenza kwe-CPP kuphelele kakhulu.
6. Vuthela ifilimu ye-IPP ebunjiwe
Ifilimu efuthwayo ye-IPP ivamise ukukhiqizwa kusetshenziswa indlela yokuphephethela phansi.Ngemuva kokuthi i-PP ikhishwe futhi yandiswe emlonyeni wesikhunta se-annular, iqale ipholiswe ngendandatho yomoya futhi icinywe ngokushesha futhi ibunjwe ngamanzi.Ngemuva kokumisa, igoqwe futhi ikhiqizwa njengefilimu ye-cylindrical, engabuye inqunywe ibe amafilimu amancane.I-IPP ebunjiwe inokukhanya okuhle, ukuqina, kanye nokwenza izikhwama okulula, kodwa ukufana kogqinsi kwayo kubi futhi ukucaba kwefilimu akwanele.
