Taw qhia rau biaxially oriented polylactic acid BOPLA
Biaxially oriented poly (lactic acid) zaj duab xis (BOPLA) yog ib yam ntawm cov khoom siv bio-raws li lub zog uas tau txais tom qab longitudinal thiab transverse stretching ntawm polylactic acid cov ntaub ntawv thiab crystallization.Biaxial stretching txheej txheem muaj xws li Step-stretching, 2. Mechanical simultaneous stretching thiab m LISIM simultaneous stretching, raws li qhia nyob rau hauv daim duab 1. Piv nrog rau lwm cov txheej txheem, cov txheej txheem biaxial stretching txhawb cov molecular orientation ntawm PLA cov ntaub ntawv, endows PLA cov ntaub ntawv uas muaj zog thiab siab kub tsis kam, thiab txo cov thickness ntawm cov khoom kom ua tiav cov khoom siv zoo tshaj plaws.BOPLA muaj qhov zoo ntawm kev sib npaug ntsug thiab kab rov tav cov khoom siv kho tshuab, siab pob tshab, siab permeability thiab zoo printability.Nws tuaj yeem hloov pauv cov yeeb yaj kiab tam sim no siv hauv e-lag luam logistics, khoom noj khoom haus qib siab, khoom siv hluav taws xob, ntawv-yas lamination thiab lwm yam.

BOPLA muaj peb qhov zoo hauv kev ua lag luam daim ntawv thov.
Ua ntej, BOPLA yog qhov zoo tshaj plaws bio-raws li pob tshab zaj duab xis ntawm kev ua lag luam.Ua tsaug rau cov yam ntxwv ntawm cov khoom thiab machinability ntawm PLA, BOPLA muaj tsawg dua cov kauj ruam ntau lawm thiab tsis ua hauj lwm nyuaj, thiab muaj qhov zoo ntawm waterproofing thiab printability ntawm tsoos polymer zaj duab xis, uas ua rau nws muaj ib tug zoo lub zeem muag nyob rau hauv daim ntawv thov nyias zaj duab xis.
Qhov thib ob, BOPLA muaj cov yam ntxwv ntawm kev degradation.Raws li cov xwm txheej khaws cia, BOPLA tuaj yeem tswj tau qhov kev ua tau zoo los lav lub txee lub neej ntawm cov khoom thiab tsis txhob ua kom luv lub txee lub neej ntawm cov khoom davhlau ya nyob twg vim muaj kev sib tsoo ntau dhau.Nyob rau hauv cov txheej txheem compost, BOPLA tuaj yeem ua tiav cov yeeb yaj kiab thinner nyob rau hauv tib lub tshuab ua haujlwm, kom nws tuaj yeem degrade sai sai hauv cov khoom sib xyaw.
Thib peb, BOPLA ua tau raws li qhov yuav tsum tau ua ntawm cov khoom lag luam thiab kev thauj mus los, thiab muaj lub hauv paus ntawm kev lag luam.Nyob rau hauv BOPLA qhov kev xeem nrawm nrawm (FIG.2), lub zog tensile tsuas yog 4.5% tom qab 1 xyoos thiab 5.2% tom qab 2 xyoos.Thaum tshav kub kub sealing zog attenuates 12.8% tom qab 1 xyoo, uas ua tau raws li qhov yuav tsum tau ntawm cov cua sov sealing kev ua tau zoo.Hauv kev sim BOPLA hiav txwv (Xiamen-Antwerp, FIG. 3), tsis muaj kev hloov pauv tseem ceeb hauv cov yeeb yaj kiab thiab cov tsos.
