Shamwari dzakawanda dzinobvunza kuti chii chiri musiyano uripo pakati pekushongedza mabhegi ekuisa uye zvizere zvinorongedza mabhegi ekuisa? Hazvisi izvo zvakafanana nehomwe inosvibisa yekuputika? Izvo hazvina kunaka, pane musiyano pakati pekushambadzira kwekuzvishongedza mabhegi uye zvizere zvinonyadzisa zvekuputika mabhegi.
Zvinosvibisa zvekuputika mabhegi, zvinoreva kuti zvinogona kusvibiswa, asi zvikanganiso zvinokatyamadza zvakakamurwa kuva "zvakashata" uye "zvakashata zvizere". Ndeupi mutsauko? Ramba uchiverenga zivo diki yakapihwa neAnrui.

Nei PBAT kuwedzerwa? ANRUI kuyedza makemikari enjinjini yakabatsira mupepeti wekududzira. PBat iri copolymer ye adipic acid, 1,4-butanedicol uye terephthalic acid. Iyo yemakemikari synthesis inogona kuve yakazara biodegarded. Iyo Alipatic Polymer yePbat ine yakanakisa shanduko uye inogona kushandiswa kune firimu Extrussion, kuputika kuumbwa, kubuda kwekuchinjisa uye kumwe kuumbwa maitiro. Chinangwa chekusanganisa pla uye pbat ndechekuvandudza kuoma, biodegradation uye kuumbwa nekurovedza kwaPla. Pla uye PHT hazvipindirani, saka kusarudza yakakodzera compaterizer inogona kuvandudza zvakanyanya kuita kwePla.
Ona pano kuti unzwisise mutsauko uripo pakati pekushongedza mabhegi ekuisa uye zvizere zvinorongedza mabhegi.
