Chiyambi cha biaxially oriented polylactic acid BOPLA
Biaxially oriented poly (lactic acid) film (BOPLA) ndi mtundu wa filimu yamphamvu kwambiri ya bio-based yomwe imapezeka pambuyo potambasulira kwautali komanso mopingasa kwa zinthu za polylactic acid ndi crystallization.Kutambasula kwa Biaxial kumaphatikizapo Kutambasula kwa Masitepe, 2. Kutambasula kwazitsulo panthawi imodzi ndi m LISIM kutambasula nthawi yomweyo, monga momwe tawonetsera pa Chithunzi 1. Poyerekeza ndi njira zina zopangira, njira yotambasula ya biaxial imalimbikitsa kayendedwe ka maselo a zipangizo za PLA, imapatsa zipangizo za PLA ndi mphamvu zambiri komanso kukana kutentha kwambiri, komanso kumachepetsa makulidwe azinthu kuti zitheke kugwiritsa ntchito bwino zinthu.BOPLA ili ndi ubwino wokhala ndi makina osunthika komanso osakanikirana, kuwonekera kwambiri, kutsekemera kwakukulu komanso kusindikiza kwabwino.Itha kusintha kwambiri filimu yomwe ikugwiritsidwa ntchito pamalonda a e-commerce, chakudya chapamwamba, zinthu zamagetsi, mapepala-pulasitiki lamination ndi zina.
Chithunzi 1. Chithunzi cha njira yotambasula ya biaxial
BOPLA ili ndi maubwino atatu pakugwiritsa ntchito msika.
Choyamba, BOPLA ndiye filimu yowoneka bwino kwambiri yopangidwa ndi bio pamsika.Chifukwa cha zinthu zakuthupi ndi machinability wa PLA, BOPLA ali ndi masitepe ochepa kupanga ndi zochepa processing zovuta, ndipo ali ubwino wa madzi ndi printability wa chikhalidwe polima filimu, zomwe zimapangitsa kukhala ndi chiyembekezo chachikulu m'munda wa woonda filimu ntchito.
Chachiwiri, BOPLA ili ndi mawonekedwe owonongeka.M'malo osungirako wamba, BOPLA imatha kukhalabe ndi magwiridwe antchito abwino kuti zitsimikizire moyo wa alumali wazinthu ndikupewa kufupikitsa moyo wa alumali wazinthu zotsalira chifukwa cha kuthamanga kwambiri pakuwonongeka.Pansi pa kompositi, BOPLA imatha kukwaniritsa makulidwe ocheperako a filimu pansi pamikhalidwe yofananira yamakina, kotero kuti imatha kunyozeka mwachangu m'malo a kompositi.
Chachitatu, BOPLA imakwaniritsa zofunikira pakusungirako zinthu wamba komanso zoyendera, ndipo ili ndi maziko ogwiritsira ntchito mafakitale.Mu mayeso okalamba ofulumira a BOPLA (FIG.2), mphamvu zamanjenje zimawola 4.5% pakatha chaka chimodzi ndi 5.2% pambuyo pa zaka ziwiri.Mphamvu yosindikiza kutentha imachepetsa 12.8% pambuyo pa chaka chimodzi, zomwe zimakwaniritsa zofunikira za ntchito yosindikiza kutentha.Mu mayesero a nyanja ya BOPLA (Xiamen-Antwerp, FIG. 3), panalibe kusintha kwakukulu kwa mafilimu ndi maonekedwe.
Chithunzi 2. BOPLA inafulumizitsa kuyesa ukalamba
Chithunzi 3. BOPLA Marine test
Makhalidwe azinthu za BOPLA akuwonetsedwa mu Gulu 1.
