Isingeniso ku-biaxially oriented polylactic acid BOPLA
Ifilimu ye-Biaxially oriented poly (lactic acid) (BOPLA) iwuhlobo lwefilimu enamandla kakhulu esekwe ku-bio etholwe ngemuva kokwelula okude nokuguquguqukayo kwe-polylactic acid kanye nokucwebezela.Inqubo yokwelula i-Biaxial ihlanganisa i-Step-stretching, 2. Ukwelula kwe-Mechanical kanyekanye kanye ne-m LISIM ukwelula ngesikhathi esisodwa, njengoba kuboniswe kuMfanekiso 1. Uma kuqhathaniswa nezinye izindlela zokucubungula, inqubo yokwelula i-biaxial ikhuthaza ukuqondiswa kwamangqamuzana ezinto ze-PLA, inika izinto ze-PLA ngamandla amakhulu futhi ukumelana nokushisa okuphezulu, futhi kunciphisa ukushuba kwemikhiqizo ukuze kuzuzwe ukusetshenziswa okungcono kakhulu kwezinto.I-BOPLA inezinzuzo zezakhiwo zemishini eziqondile nezivundlile, ukukhanya okuphezulu, ukungena okuphezulu nokuphrinta okuhle.Ingashintsha kabanzi ifilimu esetshenziswa njengamanje kwezohwebo ze-e-commerce, ukudla okusezingeni eliphezulu, imikhiqizo kagesi, i-paper-plastic lamination kanye neminye imikhakha.
Umfanekiso 1. Umdwebo wenqubo yokwelula i-biaxial
I-BOPLA inezinzuzo ezintathu ekusetshenzisweni kwemakethe.
Okokuqala, i-BOPLA iyifilimu esobala esekelwe ku-bio emakethe ethembisa kakhulu.Ngenxa yezici zezinto ezibonakalayo kanye nokusebenza kahle kwe-PLA, i-BOPLA inezinyathelo ezimbalwa zokukhiqiza nobunzima obuncane bokucubungula, futhi inezinzuzo zokuvimbela amanzi nokuphrinta kwefilimu yendabuko ye-polymer, okwenza ibe nethemba elikhulu emkhakheni wesicelo sefilimu encane.
Okwesibili, i-BOPLA inezici ezilawulekayo zokuwohloka.Ngaphansi kwezimo zokulondoloza ezivamile, i-BOPLA ingagcina ukusebenza kahle ukuze iqinisekise impilo yeshalofu yemikhiqizo futhi igweme ukufinyeza impilo yeshalofu yemikhiqizo ebulalayo ngenxa yejubane elidlulele lokuwohloka.Ngaphansi kwezimo zomquba, i-BOPLA ingafinyelela ukujiya kwefilimu encane ngaphansi kwezakhiwo ezifanayo zemishini, ukuze ikwazi ukuwohloka ngokushesha endaweni yomquba.
Okwesithathu, i-BOPLA ihlangabezana nezidingo zokuthuthwa kwempahla evamile kanye nezinto zokuhamba, futhi inesisekelo sokusebenza kwezimboni.Ekuhlolweni kokuguga okusheshisiwe kwe-BOPLA (FIG.2), amandla e-tensile abola kuphela ngo-4.5% ngemva konyaka ongu-1 kanye no-5.2% ngemva kweminyaka engu-2.Amandla okuvalwa kokushisa ehlisa u-12.8% ngemva konyaka ongu-1, ohlangabezana nezidingo zokusebenza kokuvala ukushisa.Ezivivinyweni zolwandle ze-BOPLA (i-Xiamen-Antwerp, i-FIG. 3), kwakungekho ushintsho oluphawulekayo kuzakhiwo zefilimu nokubukeka.
Umfanekiso 2. I-BOPLA isheshise ukuhlolwa kokuguga
Umfanekiso 3. Ukuhlolwa kwe-BOPLA Marine
Izici zemikhiqizo ye-BOPLA ziboniswa kuThebula 1.
