Polylactic acid (PLA) ndi crystallized polylactic acid (CPLA) ndi zinthu ziwiri zoteteza chilengedwe zomwe zatchuka kwambiri.PLA ndiCPLA kulongedzaMakampani m'zaka zaposachedwa. Monga mapulasitiki opangidwa ndi zamoyo, akuwonetsa ubwino wodziwika bwino pa chilengedwe poyerekeza ndi mapulasitiki achikhalidwe a petrochemical.
Matanthauzidwe ndi Kusiyana Pakati pa PLA ndi CPLA
PLA, kapena polylactic acid, ndi bio-plastic yopangidwa kuchokera ku zinthu zongowonjezedwanso monga chimanga kapena nzimbe kudzera mu kuwiritsa, polymerization, ndi njira zina. PLA ili ndi kuthekera kwabwino kwambiri kwa biogradient ndipo imatha kuwonongeka kwathunthu ndi tizilombo toyambitsa matenda kukhala carbon dioxide ndi madzi pansi pa mikhalidwe inayake. Komabe, PLA ili ndi kukana kutentha kochepa ndipo nthawi zambiri imagwiritsidwa ntchito kutentha pansi pa 60°C.
CPLA, kapena crystallized polylactic acid, ndi chinthu chosinthidwa chomwe chimapangidwa ndi crystallizing PLA kuti chikhale cholimba kwambiri pa kutentha. CPLA imatha kupirira kutentha kopitilira 90°C, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pakufunika kutentha kwambiri. Kusiyana kwakukulu pakati pa PLA ndi CPLA kuli mu kutentha kwawo komanso kukana kutentha, ndipo CPLA ili ndi mitundu yosiyanasiyana ya ntchito.
Zotsatira za PLA ndi CPLA pa Zachilengedwe
Kupanga kwa PLA ndi CPLA kumadalira pa zinthu zopangira biomass, zomwe zimachepetsa kwambiri kudalira zinthu zopangira petrochemical. Pakukula kwa zinthu zopangira izi, carbon dioxide imayamwa kudzera mu photosynthesis, zomwe zimapangitsa kuti mpweya usalowerere m'malo mwake nthawi yonse ya moyo wawo. Poyerekeza ndi mapulasitiki akale, njira zopangira PLA ndi CPLA zimatulutsa mpweya wochepa kwambiri wowonjezera kutentha, motero zimachepetsa zotsatira zake zoyipa zachilengedwe.
Kuphatikiza apo,PLA ndi CPLA zimatha kuwola zitatayidwa, makamaka m'malo opangira manyowa m'mafakitale, komwe zimatha kuwonongeka kwathunthu mkati mwa miyezi ingapo. Izi zimachepetsa mavuto a kuipitsa kwa nthawi yayitali kwa zinyalala za pulasitiki m'chilengedwe komanso zimachepetsa kuwonongeka kwa nthaka ndi zachilengedwe zam'madzi zomwe zimachitika chifukwa cha zinyalala za pulasitiki.
Ubwino wa PLA ndi CPLA pa Zachilengedwe
Kuchepetsa Kudalira Mafuta a Zakale
PLA ndi CPLA zimapangidwa kuchokera ku zinthu zongowonjezedwanso monga chimanga kapena nzimbe, mosiyana ndi mapulasitiki akale omwe amadalira zinthu za petrochemical. Izi zikutanthauza kuti njira yawo yopangira imachepetsa kwambiri kudalira zinthu zosangowonjezedwanso monga mafuta, kuthandiza kusunga mafuta opangidwa ndi zinthu zakale ndikuchepetsa mpweya woipa wa carbon, motero kuchepetsa kusintha kwa nyengo.
Mphamvu Yopanda Mpweya wa Carbon
Popeza zinthu zopangira biomass zimayamwa carbon dioxide panthawi yomwe zikukula kudzera mu photosynthesis, kupanga ndi kugwiritsa ntchito PLA ndi CPLA kumatha kupangitsa kuti carbon isalowerere. Mosiyana ndi zimenezi, kupanga ndi kugwiritsa ntchito mapulasitiki achikhalidwe nthawi zambiri kumabweretsa mpweya woipa kwambiri wa carbon. Chifukwa chake, PLA ndi CPLA zimathandiza kuchepetsa mpweya woipa womwe umawononga chilengedwe pa moyo wawo wonse, zomwe zimathandiza kuchepetsa kutentha kwa dziko lapansi.
Kuwonongeka kwa zinthu zachilengedwe
PLA ndi CPLA zimawonongeka bwino kwambiri, makamaka m'malo opangira manyowa m'mafakitale komwe zimatha kuwonongeka kwathunthu mkati mwa miyezi ingapo. Izi zikutanthauza kuti sizimapitirirabe m'chilengedwe monga mapulasitiki achikhalidwe, zomwe zimachepetsa kuipitsidwa kwa nthaka ndi nyanja. Kuphatikiza apo, zinthu zomwe PLA ndi CPLA zimawononga ndi carbon dioxide ndi madzi, zomwe sizivulaza chilengedwe.
Kubwezeretsanso
Ngakhale kuti njira yobwezeretsanso zinthu zamoyo ikupitabe patsogolo, PLA ndi CPLA zili ndi njira zina zobwezeretsanso zinthu. Ndi kupita patsogolo kwa ukadaulo ndi chithandizo cha mfundo, kubwezeretsanso zinthu za PLA ndi CPLA kudzafalikira kwambiri komanso kugwira ntchito bwino. Kubwezeretsanso zinthuzi sikungochepetsa zinyalala za pulasitiki komanso kumasunga zinthu ndi mphamvu.
Choyamba, kugwiritsa ntchito PLA ndi CPLA kungachepetse kugwiritsa ntchito zinthu za petrochemical ndikulimbikitsa kugwiritsa ntchito zinthu zokhazikika. Monga zinthu zopangidwa ndi zamoyo, zimachepetsa kugwiritsa ntchito mafuta akale panthawi yopanga, motero zimachepetsa mpweya woipa wa carbon.
Kuchepetsa Kuipitsidwa kwa Zinyalala za Pulasitiki
Chifukwa cha kuwonongeka mwachangu kwa PLA ndi CPLA pansi pa mikhalidwe inayake, zimatha kuchepetsa kwambiri kuchuluka kwa zinyalala za pulasitiki m'chilengedwe, kuchepetsa kuwonongeka kwa zachilengedwe zapadziko lapansi ndi zam'madzi. Izi zimathandiza kuteteza mitundu yosiyanasiyana ya zamoyo, kusunga bwino zachilengedwe, komanso kupereka malo okhala abwino kwa anthu ndi zamoyo zina.
Kupititsa patsogolo Kugwiritsa Ntchito Zinthu Mwanzeru
Monga zinthu zopangidwa ndi zamoyo, PLA ndi CPLA zimatha kugwiritsa ntchito bwino zinthu pogwiritsa ntchito njira zobwezeretsanso ndi kuwononga zinthu. Poyerekeza ndi mapulasitiki akale, njira zawo zopangira ndi kugwiritsa ntchito zinthuzi ndizotetezeka kwambiri ku chilengedwe, zomwe zimachepetsa kuwononga mphamvu ndi zinthu zomwe zimagwiritsidwa ntchito komanso zimathandizira kuti zinthu zigwiritsidwe ntchito bwino.
Chachiwiri, kuwonongeka kwa PLA ndi CPLA kumathandiza kuchepetsa kuipitsa chilengedwe komwe kumabwera chifukwa cha kutayira zinyalala ndi kutentha. Kuphatikiza apo, zinthu zomwe PLA ndi CPLA zimawononga ndi carbon dioxide ndi madzi, zomwe sizimayambitsa kuipitsa chilengedwe.
Pomaliza, PLA ndi CPLA nazonso zimatha kubwezeretsedwanso. Ngakhale kuti njira yobwezeretsanso zinthu zamoyo sizinakhazikitsidwe mokwanira, ndi kupita patsogolo kwa ukadaulo ndi kulimbikitsa mfundo, kubwezeretsanso zinthu za PLA ndi CPLA kudzafalikira kwambiri. Izi zichepetsa kwambiri kuwononga zinyalala za pulasitiki komanso kuonjezera kugwiritsa ntchito bwino zinthu.
Mapulani Oyenera Oyendetsera Zachilengedwe
Kuti tizindikire bwino ubwino wa PLA ndi CPLA pa chilengedwe, pakufunika kusintha kwadongosolo pakupanga, kugwiritsa ntchito, ndi kubwezeretsanso. Choyamba, makampani ayenera kulimbikitsidwa kugwiritsa ntchito PLA ndi CPLA ngati njira zina m'malo mwa mapulasitiki achikhalidwe, zomwe zimalimbikitsa chitukuko cha njira zopangira zinthu zobiriwira. Maboma akhoza kuthandizira izi kudzera mu mfundo zolimbikitsira ndi ndalama zothandizira kuti makampani opanga mapulasitiki azitha kugwiritsa ntchito zinthu zachilengedwe.
Chachiwiri, kulimbitsa ntchito yomanga njira zobwezeretsanso ndi kukonza zinthu za PLA ndi CPLA n'kofunika kwambiri. Kukhazikitsa njira yonse yosankhira ndi kubwezeretsanso zinthu kumaonetsetsa kuti ma bioplastics amatha kulowa bwino munjira zobwezeretsanso zinthu kapena kupanga manyowa. Kuphatikiza apo, kupita patsogolo kwa ukadaulo wokhudzana ndi izi kungathandize kuti PLA ndi CPLA ziyambe kubwezeretsanso zinthu komanso kuti PLA ndi CPLA ziyambe kuwononga zinthu.
Kuphatikiza apo, maphunziro ndi chidziwitso cha anthu onse chiyenera kukulitsidwa kuti anthu azidziwa bwino komanso azifunitsitsa kugwiritsa ntchitoZogulitsa za PLA ndi CPLAKudzera mu zochitika zosiyanasiyana zotsatsa malonda ndi maphunziro, chidziwitso cha anthu pazachilengedwe chingalimbikitsidwe, kulimbikitsa kugwiritsa ntchito zinthu zachilengedwe moyenera komanso kusankha zinyalala.
Zotsatira Zachilengedwe Zoyembekezeredwa
Mwa kugwiritsa ntchito njira zomwe zili pamwambapa, zotsatira zotsatirazi za chilengedwe zikuyembekezeredwa. Choyamba, kugwiritsa ntchito kwambiri PLA ndi CPLA m'malo opakira kudzachepetsa kwambiri kugwiritsa ntchito mapulasitiki a petrochemical, motero kuchepetsa kuipitsidwa kwa pulasitiki kuchokera ku gwero. Chachiwiri, kubwezeretsanso ndi kuwonongeka kwa mapulasitiki okhala ndi zamoyo kudzachepetsa bwino vuto la chilengedwe chifukwa cha kutaya zinyalala ndi kutentha, ndikukweza ubwino wa chilengedwe.
Pa nthawi yomweyo, kukwezedwa ndi kugwiritsidwa ntchito kwa PLA ndi CPLA kudzatsogolera chitukuko cha mafakitale obiriwira ndikulimbikitsa kukhazikitsidwa kwa chitsanzo cha chuma chozungulira. Izi sizimangothandiza kugwiritsa ntchito bwino zinthu komanso zimathandizira kupanga zatsopano zaukadaulo ndi kukula kwachuma m'mafakitale ena okhudzana nazo, ndikupanga njira yabwino yopititsira patsogolo chitukuko chobiriwira.
Pomaliza, popeza zipangizo zatsopano zosawononga chilengedwe, PLA ndi CPLA zikuwonetsa kuthekera kwakukulu kochepetsa kugwiritsa ntchito zinthu zachilengedwe komanso kuipitsa chilengedwe. Ndi chitsogozo choyenera cha mfundo ndi chithandizo chaukadaulo, kugwiritsidwa ntchito kwawo kwakukulu m'munda wopaka zinthu kumatha kukwaniritsa zotsatira zomwe zimafunidwa pa chilengedwe, zomwe zimathandiza kwambiri kuteteza chilengedwe cha Dziko Lapansi.
