Cov yas degradableyog ib hom tshiab ntawm cov khoom siv yas.Thaum lub sijhawm kev tiv thaiv ib puag ncig tau dhau los ua qhov tseem ceeb, cov yas degradable yog ECO ntau dua thiab tuaj yeem hloov pauv rau PE / PP hauv qee txoj kev.
Muaj ntau hom yas degradable, feem ntau siv ob yogPLAthiabPBAT, PLA cov tsos yog feem ntau yellowish granules, raw khoom yog los ntawm cov nroj tsuag xws li pob kws, qab zib thiab lwm yam. PBAT cov tsos yog feem ntau dawb granules, raw khoom yog los ntawm cov roj.
PLA muaj cov thermal stability zoo, hnyav hnyav, thiab tuaj yeem ua tiav ntau txoj hauv kev, xws li extrusion, spinning, stretching, txhaj tshuaj, tshuab molding.PLA tuaj yeem siv rau: straw, cov thawv ntim khoom noj, cov ntaub ntawv tsis-woven, kev lag luam thiab pej xeem fabrics.
PBAT tsis yog tsuas yog zoo ductility thiab elongation ntawm so, tab sis kuj zoo kub kuj thiab cuam tshuam kev ua tau zoo.Nws tuaj yeem siv rau hauv Ntim, tableware, fwj tshuaj pleev ib ce, lub raj mis tshuaj, cov yeeb yaj kiab ua liaj ua teb, tshuaj tua kab thiab cov ntaub ntawv tso tawm qeeb.
Tam sim no, lub ntiaj teb no PLA muaj peev xwm ntau lawm yog hais txog 650000 tons, Tuam Tshoj muaj peev xwm yog hais txog 48000 tons / xyoo, tab sis nyob rau hauv Tuam Tshoj PLA tej yaam num nyob rau hauv kev tsim kho yog hais txog 300000 tons / xyoo, thiab lub sij hawm ntev kev npaj muaj peev xwm yog li ntawm 2 lab tons / xyoo. xyoo.
Rau PBAT, lub peev xwm thoob ntiaj teb yog li 560000 tons, Tuam Tshoj muaj peev xwm yog li 240000, lub peev xwm mus sij hawm ntev yog kwv yees li 2 lab tons / xyoo, Tuam Tshoj yog cov neeg tsim khoom loj tshaj plaws ntawm PBAT hauv ntiaj teb.
