Cov polymer zoo meej-ib qho uas sib npaug ntawm lub cev thiab kev ua haujlwm ib puag ncig-tsis muaj, tab sis polybutylene adipate co-terephthalate (PBAT) los ze dua ntau.
Cov neeg tsim khoom ntawm cov khoom siv hluavtaws muaj ntau xyoo lawm tsis tuaj yeem tso tseg lawv cov khoom los ntawm kev xaus rau hauv qhov chaw pov tseg thiab dej hiav txwv, thiab tam sim no lawv raug yuam kom ua lub luag haujlwm.Muaj ntau qhov kev rov ua dua tshiab los txhawb kev rov ua dua tshiab los tiv thaiv cov neeg thuam.Lwm lub tuam txhab tab tom sim daws qhov teeb meem pov tseg los ntawm kev nqis peev hauv biodegradable biobased plastics xws li polylactic acid (PLA) thiab polyhydroxyalkanoate (PHA), vam tias ntuj degradation yuav txo qis qee qhov pov tseg.
Tab sis ob qho tib si rov siv dua thiab biopolymers ntsib teeb meem.Txawm hais tias muaj ntau xyoo ntawm kev siv zog, cov khoom siv yas rov ua dua tshiab hauv Asmeskas, piv txwv li, tseem tsawg dua 10%.Thiab biopolymers - feem ntau cov khoom ntawm fermentation - tawm tsam kom ua tiav tib yam kev ua tau zoo thiab kev tsim cov nplai ntawm cov tsim hluavtaws polymers lawv tau hloov.
PBAT ua ke qee qhov txiaj ntsig zoo ntawm cov khoom siv hluavtaws thiab biobased polymers.Nws yog muab los ntawm cov khoom siv petrochemical-purified terephthalic acid (PTA), butanediol, thiab adipic acid-thiab tseem yog biodegradable.Raws li cov khoom siv hluavtaws, nws tuaj yeem ua tiav ntawm qhov loj, thiab nws muaj cov khoom siv lub cev xav tau los ua cov yeeb yaj kiab hloov tau yooj yim uas sib tw cov khoom siv los ntawm cov pa yas.
Suav PTA txiag Hengli.Cov ntsiab lus tsis meej, thiab lub tuam txhab tsis tuaj yeem hu rau kev tawm tswv yim.Hauv kev tshaj tawm thiab kev tshaj tawm nyiaj txiag, Hengli tau hais ntau yam hais tias nws tab tom npaj cog 450,000 t lossis 600,000 t cog rau biodegradable plastics.Tab sis thaum piav qhia txog cov ntaub ntawv xav tau rau kev nqis peev, lub tuam txhab npe PTA, butanediol, thiab adipic acid.
PBAT kub maj yog qhov loj tshaj plaws hauv Suav teb.Tuam Tshoj chemical distributor CHEMDO tej yaam num uas Suav PBAT ntau lawm yuav nce mus txog 400,000 t nyob rau hauv 2022 los ntawm 150,000 t nyob rau hauv 2020.
