Umkhiqizi ochwepheshe wemishini yokushisa ukushisa.
Umnotho Oyindilinga kanye Nokufaneleka Kwawo Ezinkomishi Zepulasitiki Ze-PLA
Umnotho oyindilinga uyimodeli efuna ukunciphisa ukumosha nokusebenzisa ngokugcwele izinsiza ezitholakalayo. Esikhundleni sokulandela uhlelo olujwayelekile "thatha, yenza, lahla", umnotho oyindilinga uhlose ukuklama imikhiqizo ezosetshenziswa kabusha, igaywe kabusha, futhi iphinde isetshenziswe. Lokhu kubaluleke kakhulu kumongo wokusetshenziswa kwepulasitiki okukodwa, okuvame ukuphelela ezindaweni zokulahla imfucumfucu noma olwandle.
Ipulasitiki ye-PLA, i-biodegradable kanye ne-compostable esikhundleni samapulasitiki avamile asekelwe ku-petroleum, izuza amandla amakhulu njengengxenye yokushintshela emnothweni oyindilinga. I-PLA itholakala ezinsizeni ezivuselelekayo ezifana nesitashi sombila noma umoba, okuyenza ibe inketho esimeme uma iqhathaniswa nepulasitiki yendabuko. Kodwa-ke, naphezu kwezinzuzo zayo zemvelo, i-PLA iphinde iveze izinselelo eziyingqayizivele kubakhiqizi, ikakhulukazi uma kuziwa emishini yokukhiqiza. Ngenhlanhla, imishini yokukhiqiza inkomishi yepulasitiki ye-PLA iyazivumelanisa nezimo ukuze ihlangabezane nalezi zinselele, isiza ukuqhubekisela phambili umnotho oyindilinga.
Ukushintshaniswa Okubalulekile Emshinini Wokwenza indebe yePlastiki ye-PLA
Enye yezingxenye ezibalulekile zomnotho oyindilinga ukunciphisa ukusetshenziswa kwamandla, futhi ukukhiqizwa kwenkomishi yepulasitiki ye-PLA nakho. Ukukhiqizwa kwezinkomishi ezisekelwe ku-PLA ngokwemvelo ukonga amandla uma kuqhathaniswa nezinto zepulasitiki zendabuko, kodwa abakhiqizi basazama ukunciphisa ukusetshenziswa kwamandla ngokuqhubekayo. Imishini Emisha Yokwenza Inkomishi Yepulasitiki Yepulasitiki Ye-PLA ihlanganisa ubuchwepheshe okonga amandla njengamasistimu okushisa athuthukisiwe, asebenzisa amandla amancane ukuze afinyelele amazinga okushisa adingekayo ukuze kucutshungulwe i-PLA.
Ukwengeza, Imishini Yokwenza indebe yePlastiki ye-PLA iklanywa kucatshangwa ngokusebenza kahle kwamandla. Isibonelo, izinhlelo ezizenzakalelayo zethulwe ezivumela ukulawula okunembe kakhudlwana komjikelezo wokushisisa nokupholisa, okunciphisa ukumosheka kwamandla ngesikhathi sokukhiqiza. Lezi zindlela ezintsha azigcini nje ngokunciphisa izindleko zokusebenza kodwa futhi zisekela imigomo yokusimama ngokwehlisa i-carbon footprint yenqubo yokukhiqiza.
Gxila ku-Biodegradability kanye Nezixazululo Zokuphela Kokuphila
Isici esichazayo se-PLA ukubola kwayo, okuyenza ibe inketho evumelana nemvelo kunopulasitiki bendabuko. Kodwa-ke, ukuze basebenzise ngokugcwele amandla okusimama kwe-PLA, abakhiqizi bagxile ekuqinisekiseni ukuthi izinkomishi ze-PLA zingacutshungulwa futhi zenziwe umquba ngendlela efanele ngemva kokusetshenziswa.
Enye yezinto ezijabulisa kakhulu ekuthuthukisweni kokukhiqizwa kwenkomishi yepulasitiki ye-PLA ukusetshenziswa kwe-PLA egaywe kabusha yangemva komthengi njengempahla eluhlaza. Njengamapulasitiki endabuko, i-PLA ingasetshenziswa kabusha, futhi ingasetshenziswa ukukhiqiza izinkomishi ezintsha, okunomthelela emnothweni oyindilinga.
Le mishini yepulasitiki ye-thermoforming yenkomishi yenzelwe ukucubungula i-PLA kahle, igcine ikhwalithi namandla omkhiqizo wokugcina kuyilapho isekela uhlelo oluvaliwe lwezinkomishi ze-PLA.
Izinselele kanye Nekusasa Elizayo Lokukhiqiza Indebe Yepulasitiki Ye-PLA
Ngenkathi i-PLA yethula enye indlela ethembisayo kumapulasitiki endabuko, kusenezinselelo okufanele zinqotshwe. Esinye sezithiyo ezibaluleke kakhulu isidingo sengqalasizinda ethuthukisiwe yokuqoqwa, ukuhlungwa, nokugaywa kabusha kwezinkomishi ze-PLA. Ngokungafani ne-PET noma i-PP, izinkomishi ze-PLA azikwazi ukugaywa kabusha kuzo zonke izindawo ezikhona zokugaywa kabusha kwepulasitiki. Ukwandisa ingqalasizinda yokugaywa kabusha kwe-PLA kubalulekile ekuboneni amandla omnotho oyindilinga.
Naphezu kwalezi zinselelo, ikusasa lokwenziwa kwenkomishi yepulasitiki ye-PLA libukeka liqhakazile. Njengoba ubuchwepheshe buqhubeka nokuthuthuka kanye nesidingo sezinye izindlela ezisimeme sikhula, imishini yokukhiqiza inkomishi yepulasitiki ye-PLA izoqhubeka nokuvela, inikeza izixazululo ezisebenza kahle, ezingabizi kakhulu, nezinobungani nemvelo.
