Nhanganyaya kune biaxially oriented polylactic acid BOPLA
Biaxially oriented poly (lactic acid) firimu (BOPLA) imhando yepamusoro-yakasimba bio-yakavakirwa firimu zvinhu zvakawanikwa mushure mekureba uye kuchinjika kutambanudza kwepolylactic asidhi zvinhu uye crystallization.Biaxial kutambanudza nzira inosanganisira Nhanho-kutambanudza, 2. Mechanical panguva imwechete kutambanudza uye m LISIM panguva imwechete kutambanudza, sezvinoratidzwa mumufananidzo 1. Kuenzaniswa nedzimwe nzira dzekugadzirisa, biaxial kutambanudza nzira inokurudzira kutaridzika kwema molecular yePLA zvinhu, inopa PLA zvinhu zvine simba guru uye high heat resistance, uye inoderedza ukobvu hwezvigadzirwa kuti uwane kushandiswa kwakanyanya kwezvinhu.BOPLA ine mabhenefiti eiyo yakaenzana vertical uye yakatwasuka mechanical zvivakwa, kujeka kwepamusoro, kupenya kwepamusoro uye kudhinda kwakanaka.Inogona kutsiva zvakanyanya firimu riri kushandiswa mu e-commerce logistics, chikafu chepamusoro-soro, zvigadzirwa zvemagetsi, pepa-plastiki lamination uye mamwe minda.
Mufananidzo 1. Dhiagiramu ye biaxial kutambanudza nzira
BOPLA ine mabhenefiti matatu mumusika application.
Chekutanga, BOPLA ndiyo inonyanya kuvimbisa bio-based transparent firimu pamusika.Nekuda kwehunhu hwezvinhu uye machinability ePLA, BOPLA ine nhanho shoma dzekugadzira uye kushomeka kwekugadzirisa, uye ine zvakanakira kudzivirira mvura uye kudhindwa kwechinyakare polymer firimu, izvo zvinoita kuti ive netarisiro yakakura mundima yekushandiswa kwemafirimu matete.
Chechipiri, BOPLA ine hunhu hwekudzikisira hunodzoreka.Pasi pemamiriro ekuchengetedza akajairwa, BOPLA inogona kuchengetedza kuita kwakanaka kuvimbisa hupenyu hwesherufu yezvigadzirwa uye kudzivirira kupfupisa hupenyu hwesherufu yezvigadzirwa zvekupedzisira nekuda kwekunyanya kushatisa kumhanya.Pasi pemacompost mamiriro, BOPLA inogona kuwana yakaonda firimu ukobvu pasi pemichina michanicha zvinhu, kuitira kuti inogona kuderera nekukurumidza munzvimbo yecompost.
Chechitatu, BOPLA inosangana nezvinodiwa zveyakajairwa warehousing uye zvinhu zvekufambisa, uye ine hwaro hwekushandiswa kwemaindasitiri.MuBOPLA's accelerated aging test (FIG.2), simba rekusimba rinoora chete 4.5% mushure me1 gore uye 5.2% mushure memakore maviri.Simba rekuvhara kupisa rinoderedza 12.8% mushure megore rimwe, rinosangana nezvinodiwa zvekushanda kwekuvhara kupisa.MuBOPLA gungwa bvunzo (Xiamen-Antwerp, FIG. 3), pakanga pasina shanduko yakakosha muzvinhu zvemufirimu uye kutaridzika.
Mufananidzo 2. BOPLA yakakurumidza kuchembera bvunzo
Mufananidzo 3. BOPLA Marine test
Hunhu hweBOPLA zvigadzirwa zvinoratidzwa muTafura 1.
