Folasaga ile biaxially oriented polylactic acid BOPLA
Biaxially oriented poly (lactic acid) ata tifaga (BOPLA) o se ituaiga maualuga-malosi mea bio-faavae ata tifaga maua ina ua uma le longitudinal ma transverse faaloaloa o mea polylactic acid ma crystallization.Biaxial stretching process e aofia ai Step-stretching, 2. Mechanical simultaneous stretching and m LISIM simultaneous stretching, e pei ona faʻaalia i le Ata 1. Faʻatusatusa i isi metotia faʻagasologa, o le biaxial faʻalauteleina le faʻalauteleina o le faʻaogaina o le mole mole o mea PLA, tuʻuina atu mea PLA ma le malosi maualuga ma maualuga vevela tetee, ma faʻaitiitia le mafiafia o oloa e ausia ai le faʻaogaina sili o mea.O le BOPLA o loʻo i ai le lelei o mea faʻainisinia paleni ma faʻalava, maualuga le manino, maualuga maualuga ma lelei lolomi.E mafai ona suia lautele le ata o loʻo faʻaaogaina nei i le e-commerce logistics, meaʻai maualuga, oloa faʻaeletoroni, lamination pepa-palasitika ma isi fanua.
Ata 1. Fa'ata o le fa'asologa fa'alua
BOPLA e tolu tulaga lelei i le faʻaogaina o maketi.
Muamua, o le BOPLA o le ata sili ona faʻamaonia e faʻavaeina meaola i luga o le maketi.Faʻafetai i uiga faʻapitoa ma le faʻaogaina o le PLA, o le BOPLA e laʻititi laʻasaga gaosiga ma faʻaitiitia le faʻaogaina o faigata, ma e iai le lelei o le faʻafefeteina ma le lolomiina o ata polymer masani, lea e maua ai se faʻamoemoe sili i le fanua o ata manifinifi talosaga.
Lona lua, o le BOPLA o loʻo i ai uiga faʻaleagaina.I lalo o tulaga masani e teu ai, e mafai e le BOPLA ona tausia lelei le faʻatinoga e faʻamautinoa ai le ola faʻamau o oloa ma aloese mai le faʻapuupuuina o le ola faʻamau o oloa faʻatau ona o le televave o le faʻaleagaina.I lalo o tulaga faapalaga, e mafai e le BOPLA ona ausia le mafiafia o ata manifinifi i lalo o mea faʻainisinia tutusa, ina ia mafai ona faʻaleagaina vave i le siosiomaga faapalaga.
Tolu, BOPLA faʻamalieina manaʻoga o faleteuoloa masani ma felauaiga logistics, ma ei ai le faʻavae o le faʻaaogaina o fale gaosi oloa.I le su'ega fa'avaveva'a a le BOPLA (FIG.2), e na'o le 4.5% le malosi e pala ai pe a uma le 1 tausaga ma le 5.2% pe a uma le 2 tausaga.O le malosi faʻamaufaʻailoga vevela e faʻaitiitia ai le 12.8% i le maeʻa ai o le 1 tausaga, lea e fetaui ma manaʻoga o le faʻamauina o le vevela.I su'esu'ega o le sami a le BOPLA (Xiamen-Antwerp, FIG. 3), e leai se suiga tele i meatotino ma foliga vaaia.
Ata 2. BOPLA fa'avavevave su'ega matua
Ata 3. BOPLA Su'ega o le gataifale
O uiga o oloa BOPLA o loʻo faʻaalia ile laulau 1.
