I-Bio-based BOPLA (i-Biaxially Oriented Polylactic Acid) ifilimu
I-BIONLY bio-based material yifilimu ye-polylactic acid esemgangathweni ephezulu ye-biaxially oriented (BOPLA) ephuhliswe ngu-Xiamen Changsu.Le mveliso inokwanelisa ngokufanelekileyo imfuno yabathengi abasezantsi bezinto ezikumgangatho ophezulu we-biodegradable, kunye nokubonelela ngesisombululo esomeleleyo se-China ukufezekisa i-carbon dioxide ephezulu ngo-2030 kunye nenjongo yokungathathi hlangothi kwekhabhoni kwi-2060.
I-PLA (i-polylactic acid) i-polymer ene-lactic acid eveliswa yi-biological fermentation njengeyona nto iphambili ekrwada.Izinto zayo eziluhlaza zanele kwaye ziyakwazi ukuhlaziywa, imveliso i-biodegradable.Emva kokuba isetyenzisiwe, inokuqulunqwa kwikhabhoni diokside kunye namanzi kwiqondo lobushushu elingaphezulu kwama-55 ℃ okanye phantsi kwesenzo sokutyetyiswa kwe-oksijini kunye ne-microorganism, ukuqonda ukujikeleza kwezinto kwindalo kunye nefuthe elincinci kwindalo, ngoko ke, kuluhlaza ofanelekileyo. izinto zepolymer.
Xa kuthelekiswa nezinye iindlela zokucutshungulwa, inkqubo ye-biaxial tensile inika i-PLA amandla aphezulu kunye nokuqina kwefilimu encinci, eyenza inkqubo yokuqhekeka kwezinto kunye nokhukuliseko lwe-microbial lula, ngoko inokunciphisa kakhulu ixesha le-biodegradation yezinto.Xa kuthelekiswa neepolymers zemveli ezisekelwe kwifosili, i-PLA ine-biosafety ethembekileyo, i-biodegradability kwaye inokunciphisa ukuxhomekeka kwamandla.Ekubeni i-PLA ivela kwisiseko se-bio, inempembelelo ebalulekileyo ekunciphiseni i-carbon, kwaye ukukhutshwa kwekhabhoni kuncitshiswe ngaphezu kwe-68% xa kuthelekiswa neeplastiki zemveli ezisekelwe kwi-fossil.
Umhla wePlastiki yaseYurophu: Ukuthelekiswa kokukhutshwa kwekhabhoni diokside kwinkqubo yokuvelisa i-polymer
·I-BOPLA ine-biocompatibility elungileyo kunye nokusebenza kokuthotywa, ehambelana nokusingqongileyo.
· Ukusebenza okugqwesileyo kokusetyenzwa kunye nokuzinza okuhle kokusonga kunye nokugcinwa kokujija.
· Ukukhanya okuphezulu, inkungu ephantsi, iglosi entle yomphezulu kunye nokusebenza okugqwesileyo koshicilelo.
· Ukusebenza kakuhle kokutywinwa kobushushu ngaphandle konyango olongezelelweyo.
Inkqubo yokwelula i-biaxial inokuphucula kakhulu iipropathi zomatshini zefilimu ye-PLA, kwaye yandise ngakumbi imimandla yesicelo sayo.Ingasetyenziswa kwiteyiphu, ukupakishwa kokutya, ukupakishwa okutsha, ukulanywa kwephepha, izinto zokukhulula kunye nezinye iindawo, ezibaluleke kakhulu ekunciphiseni ukupakisha, ukukhuselwa kwendalo kunye nokunciphisa ikhabhoni.
