Qhov zoo thiab qhov tsis zoo ntawm degradable PLA ntim hnab
Jul 19, 2024
Lub stretching ntawm PLA zaj duab xis nyob ntawm tus nqi stretch, kub, thiab stretch ratio. High strain rates, tsis tshua muaj kub, thiab siab tensile ratios pab rau strain-induced crystallization thaum lub sij hawm tensile txheej txheem.
PLA muaj cov khoom siv kho qhov muag zoo thiab cov qauv siab, tab sis nws qhov elongation ntawm kev tawg, lub zog tsim kua muag thiab lub zog tawg yog tsawg.
PLA nyias lub teeb xa tawm thiab gloss tuaj yeem muab piv nrog cov ntxhiab polyester PET, zoo dua li PE, nws cov tawv tawv yog siab, tensile zog thiab modulus kuj siab heev, piv rau tus tsiaj, khoov tsis kam, siab gas barrier, zoo tsis kam rau cov roj dissolution thiab roj. tsis kam.
PLA muaj zog hydrophilicity, piv nrog PE, nws muaj peev xwm luam tau zoo heev, thiab tuaj yeem siv dav hauv cov khoom ntim thiab ntim hnab rau ntau yam khoom hauv kev lag luam thiab kev ua liaj ua teb.
Kev ua tau zoo ntawm PLA ntim hnab yog tib yam li cov yeeb yaj kiab, uas tau ua tiav los ntawm zaj duab xis rau hauv hnab.
