I-Mirathane® PBAT|Inokonakala kwaye izinzileyo

I-PBAT (i-polybutylene terephthalate) sisishunqulelo se-polybutylene terephthalate.Izinto ekrwada ukulungiselela PBAT ikakhulu adipic acid (AA), terephthalic acid (PTA), butylene glycol (BDO) njengoko monomers, ngokomlinganiselo othile esterification okanye transesterification reaction kunye nepolycondensation reaction to synthesize polyadipic acid/butylene terephthalate. I-ester, kunye ne-esterification, i-polycondensation kunye ne-granulation amanyathelo amathathu okulungiselela imveliso yokugqibela.I-PBAT iqulethe amakhonkco e-benzene, ngoko inozinzo oluphezulu lwe-molecular thermal, kodwa izinga eliphantsi lokuthotywa kwe-molecular;iimolekyuli zithatha indawo enkulu kwaye zikulungele ukuxubana nezinye iimolekyuli;Inamatyathanga atyebileyo, aqinisekisa ukuguquguquka okuhle kwamatyathanga emolekyuli kwaye ngaloo ndlela i-ductility entle.

I-PBAT yi-polymer ye-semi-crystalline, ngokuqhelekileyo ukushisa kwe-crystallization kujikeleze i-110 ° C, kwaye indawo yokunyibilika i malunga ne-130 ° C, kwaye ubuninzi buphakathi kwe-1.18g / ml ~ 1.3g / ml.I-crystallinity ye-PBAT imalunga ne-30%, kwaye ukuqina kwe-Shore kungaphezulu kwe-85. I-PBAT yi-copolymer yamaqela e-aliphatic kunye ne-aromatic, edibanisa iimpawu ezigqwesileyo zokuthotywa kwe-aliphatic polyesters kunye neempawu ezilungileyo zomatshini ze-polyester ezivumba.Ukusebenza kokucubungula kwe-PBAT kufana kakhulu ne-LDPE, kwaye ifilimu inokuvuthelwa ngezixhobo zokusebenza ze-LDPE.

I-PBAT ine-biodegradability elungileyo, kwaye iimveliso ezenziwe nge-PBAT zilula kwaye zithotywa ngokupheleleyo ngoncedo lwee-microorganisms zendalo kunye neebhaktheriya, ekugqibeleni ziguqulwa zibe yi-carbon dioxide kunye namanzi.Ngenxa ductility yayo elungileyo, elongation ngexesha lekhefu, ukumelana ubushushu kunye neempawu impembelelo, PBAT ingasetyenziswa kwishishini lokupakisha zeplastiki, ezifana iingxowa zokuthenga, iingxowa zenkunkuma, njl.
