Izinkomishi ezilahlwayo
A indebe elahlwayouhlobo lwezitsha zokudla kanye nokupakisha ukudla okulahlwayo.
Izitsha Zokudla Ezilahlwayo, Izinketho Zokudlela Ziza Ngezinto Ezihlukahlukene.Izinkomishi ezilahlwayozitholakala ngezinto eziningi ezahlukahlukene, zinikeza izixazululo zazo zonke izidingo. Imikhiqizo yendebe elahlwayo ivame ukwenziwa nge-foam, i-PLA, iphepha noma i-poly plastic. Ngakho-ke izinhlobo zendebe ezilahlwayo zifaka phakathi izinkomishi zephepha, izinkomishi zepulasitiki kanye nezinkomishi ze-foam.
Izinkomishi ze-foam zilungele ukuvikela izandla eziphuzweni ezishisayo nokugcina izinga lokushisa lesiphuzo. I-polystyrene enwetshiwe isetshenziselwa ukukhiqiza izinkomishi ze-foam, kanti i-polypropylene isetshenziselwa ukukhiqiza izinkomishi zepulasitiki.
Njengoba zikhiqizwa ukusetshenziswa kanye,izinkomishi ezilahlwayokanye neminye imikhiqizo efanayo elahlwayo yakha umthombo omkhulu wemfucuza yabathengi neyendlu, njengemfucuza yephepha kanye nemfucuza yepulasitiki. Kulinganiselwa ukuthi umndeni ojwayelekile ulahla cishe ama-70izinkomishi ezilahlwayonjalo ngonyaka. Ngakho-ke ingasetshenziswa kabushaizinkomishi ezilahlwayokubonakala sengathi kubaluleke kakhulu ukuvikela imvelo.
Izinhlobo ezahlukene zezinkomishi zephepha zisebenzisa izinsiza ezivuselelekayo ezisekelwe ezitshalweni.
I-PLA iyi-bio-polymer eyenziwe ngemithombo evuselelekayo, ngakho-ke izinkomishi ze-PLA ziyisisombululo esifanele ezinkampanini ezinobungani nemvelo. Izinkomishi zephepha ngokuvamile ziyaphinde zisetshenziswe futhi zivame ukunikeza inani elihle kakhulu. Izinkomishi ze-poly zivimbela ukuvuza futhi zinciphise ukuminyana.
Izinketho Ezinobungani Nemvelo Nciphisa Umthelela Wezemvelo
Ukuthatha isinyathelo esengeziwe sokuthenga izinkomishi ezinobungani nemvelo kwandisa ukulula ngaphandle kokudala imfucuza eningi. Izinhlobo eziningi zezinkomishi zisebenzisa izindlela ezithile zokucubungula kanye nezinto zokwakha ukuze zenze izinkomishi zihlale isikhathi eside.
I-PETindebe yepulasitiki elahlwayoegcwele i-cocktail enhle kakhulu
I-PET- PET imele i-polyethylene terephthalate. Ingxenye yomndeni we-polyester, isetshenziselwa ukwenza imicu yokwenziwa kanye nezitsha zokudla neziphuzo. Imikhiqizo eyenziwe nge-PET ilula futhi inekhono lokuvimba amagesi, izinyibilikisi kanye nomswakama. Inamandla futhi ayithinteki.
Imikhiqizo eyenziwe nge-PET ingaphinde isetshenziswe.Indebe elahlwayozivame ukubhekwa njengemikhiqizo "eluhlaza okotshani" noma "enobungani nemvelo".
Ku-COPAK, sikhiqiza kuphela i-PET ne-PLA enobungani nemveloizinkomishi ezilahlwayo.
