Intshayelelo kwi-biaxially oriented polylactic acid BOPLA
Ifilimu ye-Biaxially oriented poly (lactic acid) (i-BOPLA) luhlobo lwefilimu esekelwe kwi-bio-based high-high-high-based efunyenwe emva kokwelulwa kwexesha elide kunye ne-transverse ye-polylactic acid kunye ne-crystallization.Inkqubo yokwelula i-Biaxial ibandakanya i-Step-stretching, i-2. I-Mechanical yokwelula ngaxeshanye kunye ne-m LISIM yokwelula ngaxeshanye, njengoko kuboniswe kwi-Figure 1. Xa kuthelekiswa nezinye iindlela zokucubungula, inkqubo yokwelula i-biaxial ikhuthaza ukuqhelaniswa kwe-molecular yezinto ze-PLA, inika izinto ze-PLA ezinamandla amakhulu kunye ukumelana nobushushu obuphezulu, kwaye kunciphisa ubukhulu beemveliso ukufezekisa ukusetyenziswa kakuhle kwezinto.I-BOPLA ineenzuzo zokulungelelaniswa kweepropathi ezithe nkqo kunye nezithe tye, ukucaca okuphezulu, ukunyanzeliswa okuphezulu kunye nokuprintwa okulungileyo.Inokuthi ithathe indawo yefilimu ngoku esetyenziswa kwi-e-commerce logistics, ukutya okuphezulu, iimveliso ze-elektroniki, i-lamination yephepha-plastiki kunye nezinye iindawo.

I-BOPLA ineenzuzo ezintathu kwisicelo semarike.
Okokuqala, iBOPLA yeyona filimu ithembisayo esekwe kwibhayoloji esekwe elubala kwimarike.Ngombulelo kwiimpawu zezinto eziphathekayo kunye nokunyanzeliswa kwe-PLA, i-BOPLA inamanyathelo ambalwa okuvelisa kunye nobunzima obuncinane bokucubungula, kwaye ineenzuzo zokungangeni kwamanzi kunye nokuprintwa kwefilimu yendabuko yepolymer, eyenza ibe nethemba elikhulu kwintsimi yesicelo sefilimu ebhityileyo.
Okwesibini, i-BOPLA ineempawu ezilawulekayo zokuthotywa.Ngaphantsi kweemeko zokugcina eziqhelekileyo, i-BOPLA inokugcina ukusebenza kakuhle ukuqinisekisa ubomi beshelufu yeemveliso kwaye ugweme ukunciphisa ixesha leshelufu yeemveliso ze-terminal ngenxa yesantya esiphezulu sokunciphisa.Ngaphantsi kweemeko ze-compost, i-BOPLA inokufikelela ubukhulu befilimu encinci phantsi kweempawu ezifanayo zomatshini, ukuze ikwazi ukuthotywa ngokukhawuleza kwimeko ye-compost.
Okwesithathu, i-BOPLA ihlangabezana neemfuno zokugcinwa kwezinto eziqhelekileyo kunye nothutho lwempahla, kwaye inesiseko sokusetyenziswa kwemizi-mveliso.Kuvavanyo lokuguga olukhawulezileyo lwe-BOPLA (FIG.2), amandla okuqina abola kuphela nge-4.5% emva konyaka o-1 kunye ne-5.2% emva kweminyaka emi-2.Amandla okutywinwa kobushushu athomalalisa i-12.8% emva konyaka we-1, ohlangabezana neemfuno zokusebenza kokutywinwa kobushushu.Kwiimvavanyo zolwandle ze-BOPLA (i-Xiamen-Antwerp, i-FIG. 3), kwakungekho utshintsho oluphawulekayo kwiipropati zefilimu kunye nokubonakala.
