Nekuwedzeredzwa kwekuziva kwezvakatipoteredza, kudiwa kwevanhu kwezvinhu zvine hushamwari kwezvakatipoteredza uye zvigadzirwa zvavo zviri kuwedzerawo. Compostable material PLA uye PLA compostable mabhegi ekurongedza zvishoma nezvishoma anoshandiswa zvakanyanya mumusika.
Polylactic acid, inozivikanwawo sePLA (Polylactic Acid), ipolymer inowanikwa nepolymerizing lactic acid seyakanyanya mbishi zvinhu. Kunobva zvinhu zvakabikwa zvakakwana zvakanyanya kubva kuchibage, mufarinya, zvichingodaro..Kugadzirwa kwePLA hakuna kusvibiswa, uye chigadzirwa chinogona kuvandudzwa uye kudzokororwa mune zvakasikwa.
Zvakanakira zvePLA
1.Biodegradability: Mushure mokunge PLA yakaraswa, inogona kuderedzwa zvachose mumvura uye carbon dioxide pasi pemamiriro ezvinhu chaiwo, uye zvakare kupinda mukati mekutenderera kwechisikigo, kudzivisa kusvibiswa kwenguva refu kune zvakatipoteredza zvinokonzerwa nemapurasitiki echinyakare.
2.Renewable resources: PLA inonyanya kuvepolymerized kubva kulactic acid yakatorwa kubva muchibage starch, nzimbe uye zvimwe zvirimwa, izvo zvinogadziriswa zviwanikwa, uye kuderedza kutsamira kune petroleum zviwanikwa.
3. Iine mhepo yakanaka yemhepo, oxygen permeability uye carbon dioxide permeability, inewo pfuma yekuparadzanisa kunhuhwirira. Mavhairasi uye molds anowanzo kunamatira pamusoro peiyo biodegradable mapurasitiki, saka pane kunetseka nezve chengetedzo nehutsanana. Nekudaro, PLA ndiyo yega biodegradable plastiki ine yakanakisa anti-bacterial uye anti-mold zvivakwa.
Degradation mechanism yePLA
1.Hydrolysis: Boka re ester reketani huru rakaputsika, nokudaro kuderedza uremu hwema molecular.
2.Thermal decomposition: chiitiko chakaoma chinotungamirira pakubuda kwezvinhu zvakasiyana-siyana, zvakadai semamolekemu akareruka uye mutsara uye cyclic oligomers ane zvakasiyana-siyana zvema molecular weights, pamwe chete nelactide.
3.Photodegradation: Ultraviolet radiation inogona kukonzera kuora. Ichi ndicho chinhu chikuru mukuratidzwa kwePLA kuchiedza chezuva mumapurasitiki, midziyo yekurongedza, uye maficha ekushandisa.
Kushandiswa kwePLA mumunda wekurongedza
PLA zvinhu zvinoshandiswa munzvimbo dzakasiyana siyana. Muindasitiri yekurongedza, firimu rePLA rinonyanya kushandiswa mukurongedza kwekunze kwechikafu, chinwiwa uye zvinodhaka kutsiva echinyakare epurasitiki kurongedza, kuitira kuzadzisa chinangwa chekuchengetedzwa kwezvakatipoteredza uye kusimba.
PACK MIC inonyanya kugadzira mabhegi akagadziridzwa anogona kudzokororwa uye anogona compostable.
