Mabhegi ekuputira anoshatisa anoreva kuti anogona kuderedzwa, asi kuderedzwa kunogona kukamurwa kuita "kuora" uye "kuora zvachose".
Kudzikira zvishoma kunoreva kuwedzera kwezvimwe zvinowedzera (senge starch, modified starch kana imwe cellulose, photosensitizers, biodegradants, etc.) panguva yekugadzira kuti igadzikane.
Mushure mekudonha, zviri nyore kusvibisa mapurasitiki mumamiriro echisikigo.
Kuparara kwese kunoreva kuti zvinhu zvese zvepurasitiki zvinodzikira kuita mvura necarbon dioxide. Iyo huru mbishi yechinhu ichi chakaora zvachose inogadziriswa kuita lactic acid (chibage, cassava, nezvimwewo), inova.
PLA. Polylactic acid (PLA) imhando nyowani yebio-yakavakirwa uye inogonekazve biodegradable zvinhu. Starch raw material inosaccharified kuti iwane glucose, iyo inobva yaviriswa neglucose uye mamwe madhiri.
Iyo inoshandurwa kuita yakakwirira-kuchena lactic acid, uyezve imwe molecular uremu polylactic asidhi inogadzirwa nemakemikari synthesis nzira. Iyo ine yakanaka biodegradability uye inogona kushandiswa nema microorganisms mune zvakasikwa.
Iyo inoshatiswa zvachose pasi pemamwe mamiriro uye pakupedzisira inoburitsa kabhoni dhaikisaidhi nemvura pasina kusvibisa nharaunda. Izvi zvinobatsira zvikuru kuchengetedzwa kwezvakatipoteredza uye zvinozivikanwa sechinhu chinochengetedza zvakatipoteredza. Parizvino mabhegi ekurongedza anoparara zvizere
Iyo huru bio-based material inoumbwa nePLA + PBAT, iyo inogona kuparara zvachose mumvura uye carbon dioxide mumwedzi 3-6 pasi pemamiriro ekugadzira composting (60-70 degrees), iyo isingasvibisi nharaunda.
Sei uchiwedzera PBAT Shenzhen Jiuxinda pano kuti ndikuudze kuti PBAT icopolymer ye dicarboxylic acid, 1,4-butanediol, uye terephthalic acid. Imhando ye biodegradable zvizere.
Iyo kemikari yakagadziriswa aliphatic inonhuhwirira polymer, PBAT ine yakanakisa kuchinjika uye inogona kushandiswa firimu extrusion, kufefetera kugadzirisa, extrusion coating uye kumwe kuumbwa kwekugadzira. PLA uye PBAT
Chinangwa chekusanganisa ndechekuvandudza kusimba kwePLA, biodegradation uye kuumba processability. PLA nePBAT hazvienderane, saka kusarudza akakodzera anowirirana kunogona kuita kuti kuita kwePLA kuve kwakakoshera.vandudza.
