Lub hnab khib nyiab degradable yog tsim los ntawm cov khoom siv ntuj tsim (xws li cov hmoov txhuv nplej siab, Biodegradable garbage bag cellulose, chitin) los yog cov khoom siv ua liaj ua teb thiab cov khoom siv los ntawm microbial fermentation lossis synthesis ntawm biodegradable polymers, Biodegradable khib nyiab hnab xws li thermoplastic starch plastics, aliphatic polyesters, thiab polylactic acid. , Starch / polyvinyl cawv, Biodegradable khib nyiab hnab thiab lwm yam. yog tag nrho cov xws li yas.
Cov lus piav qhia luv luv ntawm cov yam ntxwv ntawm cov txheej txheem ntawm cov hnab khib nyiab degradable: hauv cov qauv biodegradable, cov khoom siv biodegradable tau raug xaiv, Biodegradable cov hnab khib nyiab kom cov khoom tuaj yeem ua kom zoo dua biodegraded tom qab siv thiab muab pov tseg los tsim cov pa roj carbon dioxide thiab dej; Biodegradable khib nyiab hnab hmoov txhuv nplej siab, PVA (polyethylene) Cawv) thiab polycaprolactone muaj kev sib raug zoo dua, thiab ntau yam khoom siv ntuj raug ntxiv los ua kom cov khoom sib txawv ntawm cov khoom mus kom ze lossis tshaj cov khoom ntawm cov yas zoo tib yam;
Kev tsim khoom ntawm cov khoom no tau tsim cov txheej txheem sib cais nyob rau hauv tag nrho cov txheej txheem ntawm kev sib xyaw, Biodegradable khib nyiab hnab granulating, extrusion, tshuab molding, thiab lwm yam.Biodegradable khib nyiab hnab uas muaj peev xwm tsis tu ncua thiab stably nqa tawm industrial ntau lawm.
