Polylactic acid (PLA) ndi crystallized polylactic acid (CPLA) ndi zida ziwiri zokomera chilengedwe zomwe zadziwika kwambiriPLA ndiCPLA kuyikamafakitale m'zaka zaposachedwa. Monga mapulasitiki opangidwa ndi bio, amawonetsa zabwino zachilengedwe poyerekeza ndi mapulasitiki akale a petrochemical.
Matanthauzo ndi Kusiyana Pakati pa PLA ndi CPLA
PLA, kapena polylactic acid, ndi bio-pulasitiki yopangidwa kuchokera ku zinthu zongowonjezwdwa monga chimanga wowuma kapena nzimbe kudzera nayonso mphamvu, polymerization, ndi njira zina. PLA ili ndi biodegradability yabwino kwambiri ndipo imatha kuonongeka ndi tizilombo toyambitsa matenda kukhala mpweya woipa ndi madzi pamikhalidwe yapadera. Komabe, PLA imakhala ndi kutentha pang'ono ndipo imagwiritsidwa ntchito potentha pansi pa 60 ° C.
CPLA, kapena crystallized polylactic acid, ndi chinthu chosinthidwa chopangidwa ndi crystallizing PLA kuti chiwonjezere kutentha kwake. CPLA imatha kupirira kutentha pamwamba pa 90 ° C, ndikupangitsa kuti ikhale yabwino kwa mapulogalamu omwe amafunikira kukana kutentha kwambiri. Kusiyanitsa kwakukulu pakati pa PLA ndi CPLA kuli pakupanga kwawo kutentha ndi kukana kutentha, ndi CPLA yokhala ndi ntchito zambiri.
Environmental Impact of PLA ndi CPLA
Kupanga kwa PLA ndi CPLA kumachokera ku zotsalira za zotsalira zazomera, zomwe zimachepetsa kwambiri kudalira mafuta a petrochemical. Pakukula kwa zinthu izi, mpweya woipa umatengedwa kudzera mu photosynthesis, zomwe zimapangitsa kuti mpweya usalowerere m'moyo wawo wonse. Poyerekeza ndi mapulasitiki achikhalidwe, njira zopangira PLA ndi CPLA zimatulutsa mpweya wocheperako wowonjezera kutentha, motero kuchepetsa kuwononga kwawo chilengedwe.
Kuonjezera apo,PLA ndi CPLA ndi biodegradable atataya, makamaka m'malo opangira manyowa a mafakitale, komwe amatha kuonongeka pakatha miyezi ingapo. Izi zimachepetsa kuipitsidwa kwanthawi yayitali kwa zinyalala za pulasitiki m'chilengedwe ndikuchepetsa kuwonongeka kwa nthaka ndi zamoyo zam'madzi zomwe zimachitika chifukwa cha zinyalala zapulasitiki.
Ubwino Wachilengedwe wa PLA ndi CPLA
Kuchepetsa Kudalira Mafuta Otsalira
PLA ndi CPLA amapangidwa ndi zinthu zongowonjezwdwa ngati chimanga wowuma kapena nzimbe, mosiyana ndi mapulasitiki chikhalidwe kuti amadalira chuma petrochemical. Izi zikutanthauza kuti kupanga kwawo kumachepetsa kwambiri kudalira zinthu zomwe sizingangowonjezedwanso monga mafuta, kuthandizira kusunga mafuta oyaka komanso kuchepetsa mpweya wa carbon, motero kuchepetsa kusintha kwa nyengo.
Carbon Neutral Potential
Popeza zotsalira zazomera zopangira zimatenga mpweya woipa pakukula kwawo kudzera mu photosynthesis, kupanga ndi kugwiritsa ntchito PLA ndi CPLA kumatha kukwaniritsa kusalowerera ndale kwa mpweya. Mosiyana ndi zimenezi, kupanga ndi kugwiritsa ntchito mapulasitiki achikhalidwe nthawi zambiri kumabweretsa mpweya wambiri wa carbon. Chifukwa chake, PLA ndi CPLA zimathandizira kuchepetsa kutulutsa mpweya wowonjezera kutentha pa moyo wawo wonse, kuchepetsa kutentha kwa dziko.
Biodegradability
PLA ndi CPLA ali ndi biodegradability kwambiri, makamaka m'madera mafakitale kompositi kumene angathe kunyonyotsoka kwathunthu m'miyezi ingapo. Izi zikutanthauza kuti samalimbikira chilengedwe monga mapulasitiki achikhalidwe, kuchepetsa nthaka ndi kuipitsidwa kwa nyanja. Kuphatikiza apo, zinthu zowonongeka za PLA ndi CPLA ndi carbon dioxide ndi madzi, zomwe zilibe vuto kwa chilengedwe.
Recyclability
Ngakhale njira yobwezeretsanso ma bioplastics ikukulabe, PLA ndi CPLA ali ndi gawo lina la kubwezeredwa. Ndi kupita patsogolo kwaukadaulo ndi chithandizo cha mfundo, kukonzanso kwa PLA ndi CPLA kudzakhala kofala komanso kothandiza. Kubwezeretsanso zinthuzi sikungochepetsanso zinyalala za pulasitiki komanso kumateteza chuma ndi mphamvu.
Choyamba, kugwiritsa ntchito PLA ndi CPLA kungachepetse kugwiritsa ntchito zinthu zamafuta a petrochemical ndikulimbikitsa kugwiritsa ntchito zinthu mokhazikika. Monga zida zochokera ku bio, amachepetsa kugwiritsa ntchito mafuta oyambira pakupanga, potero amachepetsa kutulutsa mpweya.
Kuchepetsa Kuipitsa Zinyalala Zapulasitiki
Chifukwa cha kuwonongeka kofulumira kwa PLA ndi CPLA pansi pamikhalidwe yeniyeni, amatha kuchepetsa kwambiri kuchuluka kwa zinyalala zapulasitiki m'chilengedwe, ndikuchepetsa kuwonongeka kwa chilengedwe chapadziko lapansi ndi m'madzi. Izi zimathandiza kuteteza zamoyo zosiyanasiyana, kusunga zachilengedwe, ndikupereka malo abwino okhalamo anthu ndi zamoyo zina.
Kupititsa patsogolo Kugwiritsa Ntchito Zothandizira
Monga zida zozikidwa pazamoyo, PLA ndi CPLA zitha kugwiritsa ntchito bwino zinthu pogwiritsa ntchito njira zobwezeretsanso komanso zowononga. Poyerekeza ndi mapulasitiki achikhalidwe, kupanga kwawo ndi kugwiritsa ntchito kwawo kumakhala kogwirizana ndi chilengedwe, kumachepetsa kuwononga mphamvu ndi zida komanso kuwongolera kugwiritsa ntchito bwino zinthu.
Chachiwiri, kuwonongeka kwachilengedwe kwa PLA ndi CPLA kumathandizira kuchepetsa kuipitsidwa kwa chilengedwe komwe kumayambitsa kuchepetsa kupsinjika kwa chilengedwe kuchokera kutayira ndi kuyatsa. Kuphatikiza apo, zinthu zowonongeka za PLA ndi CPLA ndi carbon dioxide ndi madzi, zomwe sizimayambitsa kuipitsa kwachiwiri kwa chilengedwe.
Pomaliza, PLA ndi CPLA alinso ndi recyclability. Ngakhale njira yobwezeretsanso ma bioplastics sinakhazikitsidwebe, ndi kupita patsogolo kwaukadaulo komanso kukwezeleza mfundo, kukonzanso kwa PLA ndi CPLA kudzakhala kofala kwambiri. Izi zidzachepetsanso kulemedwa kwa chilengedwe cha zinyalala za pulasitiki ndikuwonjezera kugwiritsa ntchito bwino zinthu.
Mapulani Otheka Kukhazikitsa Zachilengedwe
Kuti muzindikire bwino ubwino wa chilengedwe cha PLA ndi CPLA, kuwongolera mwadongosolo kumafunika pakupanga, kugwiritsa ntchito, ndi kubwezeretsanso. Choyamba, makampani ayenera kulimbikitsidwa kuti atenge PLA ndi CPLA ngati njira zina zapulasitiki zachikhalidwe, kulimbikitsa chitukuko cha njira zopangira zobiriwira. Maboma atha kuthandizira izi pogwiritsa ntchito mfundo zolimbikitsira komanso thandizo lazachuma kuti akweze malonda apulasitiki opangidwa ndi bio.
Chachiwiri, kulimbikitsa ntchito yomanganso ndi kukonza makina a PLA ndi CPLA ndikofunikira. Kukhazikitsa njira yokwanira yosankhira ndi kukonzanso zinthu kumawonetsetsa kuti ma bioplastics amatha kulowa m'njira zobwezeretsanso kapena kupanga kompositi. Kuphatikiza apo, kupititsa patsogolo matekinoloje okhudzana nawo kumatha kupititsa patsogolo mitengo yobwezeretsanso komanso kuwonongeka kwamphamvu kwa PLA ndi CPLA.
Kuphatikiza apo, maphunziro ndi kuzindikira kwa anthu ziyenera kulimbikitsidwa kuti ziwonjezeke kuzindikira kwa ogula komanso kufunitsitsa kugwiritsa ntchito.Zinthu za PLA ndi CPLA. Kupyolera muzochitika zosiyanasiyana zotsatsira ndi maphunziro, chidziwitso cha chilengedwe cha anthu chikhoza kulimbikitsidwa, kulimbikitsa kudya kobiriwira ndi kusanja zinyalala.
Zotsatira Zachilengedwe
Pogwiritsa ntchito njira zomwe zili pamwambazi, zotsatira za chilengedwe zikuyembekezeka. Choyamba, kufalikira kwa PLA ndi CPLA m'munda wazolongedza kudzachepetsa kwambiri kugwiritsa ntchito mapulasitiki a petrochemical, potero kuchepetsa kuipitsidwa kwa pulasitiki kuchokera kugwero. Chachiwiri, kubwezeretsedwanso ndi kuwonongeka kwa mapulasitiki opangidwa ndi zamoyo kudzachepetsa kwambiri kulemedwa kwa chilengedwe kuchokera kudzala ndi kutenthedwa, kuwongolera chilengedwe.
Panthawi imodzimodziyo, kukwezedwa ndi kugwiritsa ntchito PLA ndi CPLA kudzayendetsa chitukuko cha mafakitale obiriwira ndikulimbikitsa kukhazikitsidwa kwa ndondomeko ya zachuma yozungulira. Izi sizimangothandizira kugwiritsa ntchito bwino chuma komanso zimalimbikitsa luso laukadaulo komanso kukula kwachuma m'mafakitale ogwirizana, zomwe zimapangitsa kuti chitukuko chikhale bwino.
Pomaliza, monga zida zatsopano zowononga chilengedwe, PLA ndi CPLA zikuwonetsa kuthekera kwakukulu pakuchepetsa kugwiritsa ntchito zinthu komanso kuwononga chilengedwe. Ndi chitsogozo choyenera cha ndondomeko ndi chithandizo chaukadaulo, kugwiritsa ntchito kwawo ponseponse m'munda wolongedza katundu kumatha kukwaniritsa zomwe zimafunikira zachilengedwe, zomwe zimathandizira kuteteza chilengedwe cha Dziko Lapansi.
