I-Polylactic acid (PLA) ne-Crystally Polylactic acid (CPLA) yizinto ezimbili ezinobungane bemvelo abathole ukunakwa okubalulekile kuPla futhiCIpla ukuwowaphaimboni eminyakeni yamuva. Njengamapulasitiki asuselwa kwi-bio, abonisa izinzuzo eziphawuleka zemvelo uma ziqhathaniswa namapulasitiki endabuko we-petrochemical.
Izincazelo nomehluko phakathi kwe-PLA ne-CPLA
I-PLA, noma i-polylactic acid, ipulasitiki ye-bio eyenziwe ngezinsizakusebenza ezivuselelekayo ezinjengesitashi sommbila noma umoba ngokuvutshelwa, nge-polymerization, nezinye izinqubo. I-PLA ine-biodegreatimatability enhle kakhulu futhi ingadilizwa ngokuphelele ngama-microorganisms ku-carbon dioxide namanzi ngaphansi kwezimo ezithile. Kodwa-ke, i-PLA inokumelana nokushisa okuphansi okuphansi futhi imvamisa isetshenziswa emazingeni okushisa angaphansi kuka-60 ° C.
I-CPLA, noma i-Palstaltic Polylactic Acid, iyisimo esiguquliwe esikhiqizwa nge-Crystalliting Pla ukuthuthukisa ukumelana kwayo kokushisa. I-CPLA ingamelana namazinga okushisa angenhla kwe-90 ° C, okwenza kube kuhle ngezicelo ezidinga ukumelana nokushisa okuphezulu. Umehluko omkhulu phakathi kwe-Pla kanye ne-CPLA LEAL ekusebenzeni kwawo okushisayo nokumelana nokushisa, nge-CPLA yokuba nobubanzi bezicelo ezibanzi.
Umthelela wezemvelo we-PLA ne-CPLA
Ukukhiqizwa kwePla kanye ne-CPLA kususelwa ezintweni ezisetshenziswayo ze-biomass, kunciphisa kakhulu ukuncika kwezinsizakusebenza ze-petrochemical. Ngesikhathi sokukhula kwalezi zinto ezingavuthiwe, i-carbon dioxide idonswa nge-photosynthesis, inikezela amandla okuthi ukungathathi hlangothi kwekhabhoni phezu kokuphila kwawo konke. Uma kuqhathaniswa namapulasitiki wendabuko, izinqubo zokukhiqiza ze-PLA ne-CPLA zakhipha kakhulu amagesi abamba ukushisa, ngaleyo ndlela kunciphisa umthelela wabo ongemuhle wezemvelo.
Ngokwengeziwe,I-PLA ne-CPLA BOODEGRADAGE Ngemuva kokulahlwa, ikakhulukazi ezindaweni zokuthwala zezimboni, lapho zingahle zingcolise ngokuphelele ezinyangeni ezimbalwa. Lokhu kunciphisa izinkinga zokungcola okuhlala isikhathi eside zensiza yepulasitiki endaweni yemvelo futhi kunciphisa ukulimala kwenhlabathi nasemanzini endalo yemvelo ebangelwa imfucuza yepulasitiki.
Izinzuzo zezemvelo ze-PLA ne-CPLA
Ukunciphisa ukuncika kumafutha fossil
I-PLA ne-CPLA yenziwa ngemithombo evuselelekayo efana nesitashi sommbila noma umoba, ngokungafani namapulasithi endabuko ancike kwizisetshenziswa ze-petrochemical. Lokhu kusho ukuthi inqubo yabo yokukhiqiza inciphisa kakhulu ukuncika kwizisetshenziswa ezingavuselelwa ezinjengewoyela, isiza ukonga amafutha ezinsika futhi inciphise ukukhishwa kwekhabhoni, ngaleyo ndlela kunciphise ukushintshwa kwesimo sezulu.
I-Carbon engathathi hlangothi
Njengoba izinto zokusetshenziswa ze-biomass zidonsa isikhutha sekhabhoni ngesikhathi sokukhula kwazo nge-photosynthesis, ukukhiqizwa kanye nokusetshenziswa kwe-pla kanye ne-cpla kungafinyelela ukungathathi hlangothi kwekhabhoni. Ngokuphambene, ukukhiqizwa kanye nokusetshenziswa kwamapulasitiki wendabuko kuvame ukuba nomphumela wokukhishwa okubalulekile kwekhabhoni. Ngakho-ke, i-PLA ne-CPLA isiza ukunciphisa ukuphuma kwegesi abamba ukushisa ngaphezulu kokuphila kwabo, kunciphisa ukufudumala komhlaba.
Biodegradeability
I-PLA ne-CPLA ine-biodegrade enhle kakhulu, ikakhulukazi ezindaweni zokuthwala izimboni lapho zingalimaza khona ngokugcwele ezinyangeni ezimbalwa. Lokhu kusho ukuthi abaphikeli endaweni yemvelo efana nezimpawu zendabuko, ukunciphisa inhlabathi nokungcoliswa kwasolwandle. Ngaphezu kwalokho, imikhiqizo yokucekelwa phansi ye-PLA ne-CPLA yi-carbon dioxide namanzi, angenangozi emvelweni.
Ukubuyiselwa kabusha
Yize uhlelo lokuphinda lusebenze kabusha lwama-bioplastics lusakhula, i-PLA ne-CPLA liba ne-degree ethile yokubuyisela kabusha. Ngentuthuko kwezobuchwepheshe kanye nokuxhaswa kwenqubomgomo, ukuvumelanisa kwe-PLA ne-CPLA kuzoba ukusakazeka ngokwengeziwe futhi kusebenza kahle. Ukuphinda usebenzise lezi zinto zokwakha kungaze kunciphise ukunciphisa imfucuza yepulasitiki kodwa futhi kugcina izinsiza namandla.
Okokuqala, ukusetshenziswa kwe-PLA ne-CPLA kunganciphisa ukusetshenziswa kwezinsizakusebenza ze-petrochemical futhi kukhuthaze ukusetshenziswa kwezinsizakusebenza ezizinzile. Njengezinto zokwakha ezenzelwe ama-bio, zinciphisa ukusetshenziswa kwamafutha ezinhlaka ngesikhathi sokukhiqiza, ngaleyo ndlela kwehlise ukuphuma kwekhabhoni.
Ukunciphisa ukungcoliswa kwemfucuza yepulasitiki
Ngenxa yokonakaliswa okusheshayo kwe-pla kanye ne-CPLA ngaphansi kwemibandela ethile, banganciphisa kakhulu ukuqongelela imfucuza yepulasitiki endaweni yemvelo, inciphisa umonakalo ophathelene nemvelo yemvelo yasemhlabeni neyomanzini. Lokhu kusiza ukuvikela izinhlobonhlobo zezinto eziphilayo, gcina imali esele yemvelo, futhi unikeze indawo yokuphila enempilo yabantu kanye nezinye izidalwa.
Ukuthuthukisa ukusebenza kahle kwezinsizakusebenza
Njengezinto zokwenziwa ezenzelwe ama-bio, i-PLA ne-CPLA zingafinyelela ukusetshenziswa kwezinsizakusebenza ezisebenza kahle ngezinqubo zokuphinda usebenzise kabusha kanye nokonakaliswa. Uma kuqhathaniswa namapulasitiki wendabuko, ukukhiqizwa kwabo kanye nezinqubo zokusebenzisa kwazo kungobungane ngokwemvelo, ukunciphisa amandla kanye nokungcola kwezinsiza kanye nokwenza ngcono ukusebenza kahle kwezinsizakusebenza.
Okwesibili, i-biodegradeabilibility ye-PLA ne-CPLA isiza ukudambisa ukungcoliswa kwemvelo okubandakanya ukungcoliswa kwemvelo okubangelwa ingcindezi yezemvelo kusuka ekufezeni komhlaba kanye nokushiswa. Ngokwengeziwe, imikhiqizo yokucekelwa phansi ye-PLA ne-CPLA yi-carbon dioxide namanzi, okungabangeli ukungcoliswa kwesibili emvelweni.
Okokugcina, i-PLA ne-CPLA nakho kube nokubuyiselwa kabusha. Yize uhlelo lokuphinda lusebenze kabusha lwe-bioplastics alukamiswa ngokuphelele, ngentuthuko yezobuchwepheshe kanye nokunyuswa kwenqubomgomo, ukuphinda kwenziwa kabusha kwe-PLA ne-CPLA kuzoba okuvame kakhulu. Lokhu kuzokwehlisa futhi umthwalo wemvelo wokungcola kwepulasitiki futhi uthuthukise ukusebenza kahle kwezinsiza.
Izinhlelo Zokuqalisa Kwezemvelo Ezinokwenzeka
Ukubona ngokugcwele izinzuzo zemvelo ze-PLA ne-CPLA, ukuthuthuka okuhlelekile kuyadingeka ekukhiqizweni, ukusetshenziswa, nokuphinda usebenzise kabusha. Okokuqala, izinkampani kufanele zikhuthazwe ukuthi zilandele i-PLA ne-CPLA njengezinye izindlela kumapulasitiki wendabuko, kukhuthaza ukuthuthukiswa kwezinqubo zokukhiqiza eziluhlaza. Ohulumeni bangasekela lokhu ngezinkuthazo zenqubomgomo kanye noxhaso lwezezimali ukukhuthaza imboni ye-plastics esekwe kwi-bio.
Okwesibili, okuqinisa ukwakhiwa kwezinhlelo zokuphinda usebenzise kabusha kanye nokucubungula ze-PLA ne-CPLA zibalulekile. Ukusungula uhlelo oluphelele lokuhlela nokuphinda usebenzise kabusha kuqinisekisa ukuthi ama-bioplastics angafaka ngempumelelo iziteshi zokuvuselela kabusha noma zokuhlanganisa. Ngaphezu kwalokho, ubuchwepheshe obuhlobene nabo bungathuthukisa amanani okuvuselela kabusha kanye nokusebenza kahle kwe-PLA ne-CPLA.
Ngaphezu kwalokho, imfundo yomphakathi nokuqwashisa kufanele kuthuthukiswe ukukhulisa ukuqashelwa kwabathengi nokuzimisela okuzosetshenziswaImikhiqizo ye-PLA ne-CPLA. Ngemisebenzi ehlukahlukene yokuphromotha neyemfundo, ukuqwashisa umphakathi, kukhuthaza ukusetshenziswa okuluhlaza kanye nokungcola kokuhlelwa.
Imiphumela Elindelwe Yezemvelo
Ngokusebenzisa izinyathelo ezingenhla, kulindeleke imiphumela elandelayo yezemvelo. Okokuqala, uhlelo lokusebenza olusakazekile lwe-PLA ne-CPLA ensimini yokupakisha luzonciphisa kakhulu ukusetshenziswa kwamapulasitiki we-petrochemical, ngaleyo ndlela anciphise ukungcoliswa kwepulasitiki kusuka kumthombo. Okwesibili, ukuvumelanisa kanye ne-biodegradamability yamapulasitiki asuselwa kwi-bio kuzonciphisa ngempumelelo umthwalo wemvelo kusuka ekugcwalisweni nasekunciphiseni, ethuthukisa ikhwalithi yemvelo.
Ngasikhathi sinye, ukukhushulwa kanye nokusetshenziswa kwe-PLA ne-CPLA kuzothuthukisa ukuthuthukiswa kwezimboni eziluhlaza futhi kukhuthaze ukusungulwa kwemodeli yezomnotho oyindilinga. Lokhu akugcini nje kusiza ekusetshenzisweni kwezinsiza ezizinzile kepha futhi kuqhume ama-spurs technological ubuchwepheshe kanye nokukhula komnotho kwizimboni ezihlobene, kwakha umjikelezo omuhle wokuthuthuka okuluhlaza.
Sengiphetha, njengezinto ezintsha ezinobungane bemvelo, i-PLA kanye ne-CPLA ekhombisa amandla amakhulu ekunciphiseni ukusetshenziswa kwezinsiza kanye nokungcoliswa kwemvelo. Ngokuholwa kwenqubomgomo efanelekile kanye nokuxhaswa kwezobuchwepheshe, uhlelo lwazo olubanzi ensimini yokupakisha lungafinyelela imiphumela efiselekayo yezemvelo, yenza umnikelo omuhle ukuvikela imvelo yomhlaba.
