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 yokuphephula eya phansi. Ngemuva kokuthi i-PP ikhishwe futhi yandiswe emlonyeni wesikhunta se-annular, iqale ipholiswe ngendandatho yomoya bese icinywa 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 kwayo kogqinsi kubi futhi ukucaba kwefilimu akwanele.
