Koj puas tau tshawb nrhiav lwm txoj hauv kev rau roj av-raws li cov yas thiab ntim khoom?Kev ua lag luam niaj hnub no tau nce mus rau biodegradable thiab eco-friendly cov khoom tsim los ntawm cov khoom siv txuas ntxiv mus.

PLA cov khoom lag luam tau nrawm dhau los ua ib qho ntawm cov kev xaiv biodegradable thiab ib puag ncig-phooj ywg nyob hauv khw.Ib txoj kev tshawb fawb 2017 tau pom tias hloov cov roj av-raws li plastics nrog bio-based plastics tuaj yeem txo qis kev lag luam tsev cog khoom emissions los ntawm 25%.

PLA yog dab tsi?

PLA, los yog polylactic acid, yog tsim los ntawm tej fermentable qab zib.Feem ntau PLA yog tsim los ntawm pob kws vim pob kws yog ib qho ntawm cov khoom qab zib uas pheej yig tshaj plaws thiab muaj nyob thoob plaws ntiaj teb.Txawm li cas los xij, qab zib, tapioca cag, cassava, thiab qab zib beet pulp yog lwm txoj kev xaiv.

Zoo li feem ntau ntawm chemistry ntsig txog, txheej txheem ntawm kev tsim PLA los ntawm pob kws yog qhov nyuaj heev.Txawm li cas los xij, nws tuaj yeem piav qhia hauv ob peb kauj ruam ncaj nraim.

PLA cov khoom ua li cas?

Cov kauj ruam yooj yim los tsim polylactic acid los ntawm pob kws yog raws li nram no:

1. Thawj pob kws hmoov txhuv nplej siab yuav tsum tau hloov mus rau hauv qab zib los ntawm kev siv tshuab hu ua ntub milling.Nthuav milling cais cov hmoov txhuv nplej siab los ntawm cov kernels.Acid lossis enzymes raug ntxiv thaum cov khoom sib cais.Tom qab ntawd, lawv tau rhaub kom hloov cov hmoov txhuv nplej siab rau hauv dextrose (aka qab zib).

2. Tom ntej no, lub dextrose yog fermented.Ib txoj hauv kev fermentation feem ntau suav nrog ntxivLactobacilluscov kab mob mus rau dextrose.Qhov no, nyob rau hauv lem, tsim lactic acid.

3. Cov lactic acid ces hloov mus rau hauv lactide, lub nplhaib-daim ntawv dimer ntawm lactic acid.Cov lactide molecules sib koom ua ke los tsim cov polymers.

4. Qhov tshwm sim ntawm cov polymerization yog me me ntawm cov khoom siv raw polylactic acid yas uas tuaj yeem hloov mus rau hauv ib qho array ntawmPLA cov khoom siv yas.

Cov txiaj ntsig ntawm kev ntim khoom noj:

• Lawv tsis muaj cov tshuaj lom neeg tsis zoo ib yam li cov khoom siv roj av
• Muaj zog npaum li ntau cov pa yas
• Lub freezer-kev nyab xeeb
• Cov khob muaj peev xwm tswj tau qhov kub txog li 110 ° F (PLA cov tais diav tuaj yeem tswj qhov kub txog li 200 ° F)
• Non-toxic, carbon-neutral, thiab 100% tauj dua tshiab

PLA yog kev ua haujlwm, raug nqi, thiab ruaj khov.Kev hloov mus rau cov khoom lag luam no yog ib kauj ruam tseem ceeb rau kev txo koj lub lag luam zaub mov cov pa roj carbon hneev taw.
