Ngokusetshenziswa kokuvinjelwa kwepulasitiki emhlabeni jikelele, abantu bafuna ezinye izindlela ezinobungani nemvelo esikhundleni sezitsha zepulasitiki ezilahlwayo. Izinhlobo ezahlukene zezitsha ze-bioplastic zaqala ukuvela emakethe njengezindlela ezinobungani nemvelo esikhundleni sezitsha zepulasitiki ezilahlwayo. Lezi zitsha ze-bioplastic zibukeka ngendlela efanayo. Kodwa umehluko muni? Namuhla, ake siqhathanise ezimbili zezitsha ze-bioplastic ezivame ukubonakala kakhulu i-CPLA Cutlery kanye ne-PSM Cutlery.
(1) Izinto Zokusetshenziswa
I-PSM imele izinto zesitashi sezitshalo, okuyizinto ezihlanganisiwe zesitashi sezitshalo kanye ne-plastic filler (PP). Izithasiselo zepulasitiki ziyadingeka ukuqinisa i-resin yesitashi sommbila ukuze isebenze kahle ekusetshenzisweni. Ayikho iphesenti ejwayelekile yokwakheka kwezinto. Abakhiqizi abahlukene bangasebenzisa izinto ezinamaphesenti ahlukene esitashi ekukhiqizeni. Okuqukethwe kwesitashi sommbila kungahluka kusuka ku-20% kuya ku-70%.
Izinto zokusetshenziswa esizisebenzisela izitsha ze-CPLA yi-PLA (i-Poly Lactic Acid), okuwuhlobo lwe-bio-polymer oluvela kushukela ezitshalweni ezahlukene. I-PLA iqinisekisiwe ukuthi iyabola futhi iyabola.
(2) Ukuvunda
Izitsha ze-CPLA zingaba ngumquba. Izitsha ze-PSM aziba ngumquba.
Abanye abakhiqizi bangabiza izitsha ze-PSM cutlery cornstarch cutlery futhi basebenzise igama elithi i-biodegradable ukuze balichaze. Eqinisweni, izitsha ze-PSM azikwazi ukubola. Ukusebenzisa igama elithi i-biodegradable nokugwema igama elithi i-compostable kungaba ukudukisa amakhasimende nabathengi. I-biodegradable isho ukuthi umkhiqizo ungonakala, kodwa ayinikezi ulwazi lokuthi kuzothatha isikhathi esingakanani ukonakala ngokuphelele. Ungabiza izitsha zepulasitiki ezivamile ngokuthi i-biodegradable, kodwa kungathatha iminyaka eyi-100 ukonakala!
Izitsha ze-CPLA ziqinisekisiwe ukuthi zingafakwa umquba. Zingafakwa umquba ezindaweni zokukhiqiza umquba zezimboni zingakapheli izinsuku ezingu-180.
(3) Ukumelana Nokushisa
Izitsha ze-CPLA zingamelana nokushisa okufika ku-90°C/194F kanti izitsha ze-PSM zingamelana nokushisa okufika ku-104°C/220F.
(4) Ukuzivumelanisa nezimo
Izinto ze-PLA ngokwazo ziqinile futhi ziqinile, kodwa azinazo iziguquguquki. I-PSM iguquguquka kakhulu kunezinto ze-PLA ngenxa ye-PP eyengeziwe. Uma ugoba isibambo sefoloko le-CPLA kanye nefoloko le-PSM, ungabona ukuthi ifoloko le-CPLA lizophuka futhi liphuke kuyilapho ifoloko le-PSM lizoguquguquka kakhulu futhi lingase ligobeke kuze kube ngu-90° ngaphandle kokuphuka.
(5) Izinketho Zokuphela Kwempilo
Ngokungafani nepulasitiki, izinto zesitashi sommbila nazo zingalahlwa ngokushiswa, okuholela ekuntuthweni okungeyona ubuthi kanye nezinsalela ezimhlophe ezingasetshenziswa njengomanyolo.
Ngemva kokusetshenziswa, izitsha ze-CPLA zingafakwa umquba ezindaweni zokukhiqiza umquba zezimboni zingakapheli izinsuku ezingu-180. Imikhiqizo yazo yokugcina amanzi, i-carbon dioxide, kanye ne-biomass yezakhamzimba ezingasekela ukukhula kwezitshalo.
Izitsha ze-MVI ECOPACK CPLA zenziwe ngezinsiza ezivuselelekayo. Zivunyelwe yi-FDA ukuthi zihlangane nokudla. Isethi yezitsha iqukethe ifoloko, ummese, kanye nesipuni. Ihlangabezana ne-ASTM D6400 yoKuqiniswa Kokubumba.
Izitsha ezibolayo zinika ukusebenza kwesevisi yakho yokudla ibhalansi ephelele phakathi kwamandla, ukumelana nokushisa kanye nokuba ngumquba okuhambisana nemvelo.
Uma kuqhathaniswa nezitsha zendabuko ezenziwe ngepulasitiki eyi-100% engeyona eyemvelo, izitsha ze-CPLA zenziwe ngezinto ezivuselelekayo ezingama-70%, okuyisinqumo esihlala isikhathi eside. Zilungele ukudla kwansuku zonke, izindawo zokudlela, ukuhlangana komndeni, amaloli okudla, imicimbi ekhethekile, ukupheka, imishado, amaphathi nokunye.
Jabulela ukudla kwakho ngezitsha zethu ezisekelwe ezitshalweni ukuze uphephe futhi ube nempilo enhle.
