Bio-based BOPLA (Biaxially Oriented Polylactic Acid) Filimu
BIONLY bio-based material ndi filimu yapamwamba kwambiri ya biaxially oriented polylactic acid (BOPLA) yopangidwa ndi Xiamen Changsu.Izi zitha kukwaniritsa zofuna zamakasitomala akutsika kwazinthu zowola kwambiri, komanso kupereka yankho lamphamvu kuti China ikwaniritse nsonga ya carbon dioxide mu 2030 komanso cholinga cha kusalowerera ndale kwa kaboni mu 2060.
PLA (polylactic acid) ndi polima ndi lactic acid opangidwa ndi biological fermentation monga zopangira zazikulu.Zake zopangira ndizokwanira ndipo zimatha kusinthidwanso, mankhwalawa ndi biodegradable.Pambuyo ntchito, akhoza wapangidwa kukhala mpweya woipa ndi madzi kutentha kuposa 55 ℃ kapena pansi zochita za mpweya wolemeretsa ndi tizilombo tating'onoting'ono, kuzindikira kufalitsidwa zinthu zachilengedwe ndi kukhudza pang'ono chilengedwe, Choncho, ndi wobiriwira abwino. zinthu za polima.
Poyerekeza ndi njira zina processing, biaxial kumakoka ndondomeko amapereka PLA zakuthupi mphamvu apamwamba ndi woonda filimu makulidwe, zomwe zimapangitsa ndondomeko azingokhala chuma ndi tizilombo ting'onoting'ono kukokoloka mosavuta, kotero akhoza kwambiri kufupikitsa biodegradation nthawi zinthu.Poyerekeza ndi ma polima achikhalidwe, PLA ili ndi chitetezo chodalirika cha biodegradability ndipo imatha kuchepetsa kudalira mphamvu.Popeza PLA imachokera ku bio base, imakhudza kwambiri kuchepetsa mpweya, ndipo mpweya wotulutsa mpweya umachepetsedwa ndi 68% poyerekeza ndi mapulasitiki achikhalidwe.
Tsiku lochokera ku Plastiki Europe: Kuyerekeza kwa mpweya woipa wa carbon dioxide mu njira yopangira polima
·BOPLA ili ndi biocompatibility yabwino komanso kuwononga magwiridwe antchito, omwe ndi ogwirizana ndi chilengedwe.
· Kuchita bwino kwambiri pakukonza ndi kukhazikika kwabwino kwa kupindika ndi kupotoza posungira.
· Kuwonekera kwambiri, chifunga chochepa, gloss yabwino pamwamba komanso ntchito yabwino yosindikiza.
· Ntchito yabwino yosindikiza kutentha popanda chithandizo chowonjezera.
Njira yotambasula ya biaxial imatha kusintha kwambiri makina a filimu ya PLA, ndikuwonjezeranso magawo ake ogwiritsira ntchito.Itha kugwiritsidwa ntchito mu tepi, kuyika chakudya, kuyika mwatsopano, kuyika mapepala, kutulutsa zinthu ndi magawo ena, zomwe ndizofunikira kwambiri pakuchepetsa ma CD, kuteteza chilengedwe komanso kuchepetsa mpweya.
