Esikhathini esedlule, into efakwe i-perfluorinated i-PFAS ehlanganiswe endaweni engaphakathi yokupakisha ukudla ine-carcinogenicity ethile, ngakho-ke abakhiqizi abaningi bokufaka ukudla okusheshayo kwephepha bashintshele ekuhlanganiseni ingaphezulu lephepha ngongqimba lwamapulasitiki e-resin njenge-PE, PP. , I-EVA, i-sarin, njll. Ifilimu ingafinyelela inhloso yokungangeni kwamanzi kanye nokuvikela uwoyela, futhi igweme ukulimala kwento efakwe i-PFAS ene-perfluorinated empilweni yomuntu.Kodwa-ke, endaweni yemvelo, njenge-PFAS, ukwakheka kwamangqamuzana alawa mafilimu epulasitiki kuzinzile futhi angeke konakaliswe, ngaleyo ndlela kwakheke ukungcoliswa kwepulasitiki emhlophe.#PE camera inkomishi yephepha fan

Ngakho-ke, izinkampani zaseShayina zenze futhi zakhiqiza ubuchwepheshe be-photo-oxygen biodegradation wezinto ze-polymer (ezifana nepulasitiki, irabha, nemicu yamakhemikhali), engafinyelela ukucekelwa phansi komhlaba kanye nokucekelwa phansi komquba.

I-photo-oxygen biodegradable masterbatch iwubuchwepheshe obuseduze kakhulu bokuwohloka kwemvelo ukuwohloka ngokushesha endaweni yemvelo.Ukwengezwa kwe-1% kungafinyelela ukuwohloka okusheshayo ngaphandle kokushintsha impahla, imishini yokukhiqiza, inqubo yokukhiqiza kanye nokusebenza okuphelele kwempahla.

Kodwa-ke, izindleko ze-polylactic acid yendabuko i-PLA, i-PBAT, i-PBS, i-PHA kanye nobunye ubuchwepheshe obungaboli ngokuphelele bukhuphuka okungenani ngo-100% kuya ku-200%, futhi ukusebenza okuphelele akukwazi ukufinyelela ukusebenza kwamapulasitiki endabuko, ngakho-ke izinto zokwakha, imishini yokukhiqiza nezinqubo zokukhiqiza. kudingeka kushintshwe.

Ubuchwepheshe be-photo-oxygen biodegradation bamafilimu epulasitiki afana ne-PE ne-sarin bungasetshenziswa ekukhiqizeni amaphakheji okudla okusheshayo ephepha emakethe yaseShayina.#PE coated paper roll

Umgomo wobuchwepheshe we-photo-oxygen biodegradation technology

Ubuchwepheshe befilimu yepulasitiki yenkampani yaseShayina ye-photo-oxidative biodegradation iwuhlobo lobuchwepheshe olusha oluwohloka ngokuphelele ngokusekelwe kufilimu yepulasitiki elahliwe endaweni yemvelo.Ubuchwepheshe buklanyelwe ukugcina ukuphila kwayo okusebenzisekayo njengempahla kanye nemishini yayo, imishini, isithiyo, ukubeka izinto obala nezinye izici zezentengiselwano phakathi nomjikelezo wayo wokuphila, futhi ivumela amafilimu epulasitiki ukuba amosheke ngaphansi kwezimo zemvelo ngemva kokulahlwa.

Ubuchwepheshe bokwengeza i-photo-oxygen biodegradable masterbatch efilimini yepulasitiki ukuyenza isebenze njengefilimu yepulasitiki ye-olefin ye-photo-oxygen biodegradable.Thuthukisa isivinini lapho ama-athomu omoya-mpilo afakwa khona kumaketanga e-polymer ama-polymer epulasitiki.Ama-polymer epulasitiki aphulwa abe yizinto ezincane zamangqamuzana endaweni ye-aerobic, bese aboliswa ama-microorganisms atholakala yonke indawo endaweni yemvelo.#PE coated paper floor roll

Inqubo yokuwohloka kwamafilimu epulasitiki esebenzisa ubuchwepheshe be-photo-oxygen biodegradation ingahlukaniswa izigaba ezimbili.
Isigaba sokuqala: Ifilimu yepulasitiki engezwe nge-photo-oxygen biodegradable masterbatch isabela nomoya-mpilo emoyeni, okubangela ukuthi isithasiselo sihlasele iketango le-carbon ye-polymer, futhi umgogodla we-carbon ukhishwa i-oxid ukwenza izingcezu zamangqamuzana anesisindo esihlobene ne-molecule ngaphansi kuka-10,000 noma ngaphansi ( Ososayensi baseYurophu naseJapane bakholelwa ukuthi ama-oligomers anesisindo samangqamuzana angaphansi kuka-400,000 angagwinywa ama-microorganisms).

Kulesi sigaba, ukuwohloka kuyinqubo ye-abiotic, ekhuthaza ukufakwa kwama-athomu omoya-mpilo ku-carbon backbone lapho i-polymer iphuka ukuze yakhe amaqembu ahlukahlukene asebenzayo (njengama-carboxylic acid, esters, aldehydes, nama-alcohol).

I-polymer ephezulu yamangqamuzana ishintsha isuka ochungechungeni lwe-hydrophobic macromolecule iye kuyiketango elincane le-hydrophilic lamangqamuzana, okwenza izingcezu zeketango lamangqamuzana kube lula ukuguguleka nokugaya amagciwane.# Ifeni yenkomishi yephepha lempahla eluhlaza

Isigaba sesibili: amagciwane atholakala yonke indawo (amabhaktheriya, isikhunta nolwelwe) emvelweni abola ifilimu yepulasitiki njengomthombo wezakhi, futhi ekugcineni ayibolise ibe yi-carbon dioxide, amanzi kanye ne-biomass.Ukuwohloka kulesi sigaba kubizwa ngokuthi inqubo ye-biodegradation.

Ukuhlola kanye Namazinga

Kungakhathaliseki ukuthi kusendaweni evulekile noma elabhorethri, izinga lokuwohloka kwalobu buchwepheshe lingafinyelela ngaphezu kwama-60%.Emazingeni kazwelonke wezwe lami i-GB/T 20197-2006 kanye ne-GB/T 19277.1-2011, izidingo eziphakeme kakhulu zokuhlola izinga lokuwohloka kwemvelo ngu-60%.

Esimeni saselabhorethri, kumafilimu anogqinsi olungaphansi kuka-15 μm, angangena esigabeni se-biodegradation ngemva kokulingisa izinyanga ezi-3 zokuguga kwemvelo.Ukuguga okulingiswayo kungakhetha ukuguga kwe-UV noma ukuguga kwesibani se-xenon.

Ukungena esigabeni se-biodegradation, izinga elithuthuke kakhulu lokucekelwa phansi kwe-polyolefin emhlabeni (PAS 9017: 2020) lidinga izinga lokuwohloka elingaphezu kwama-90% zingakapheli izinsuku ezingama-730, eliphakeme kakhulu kunezinga likazwelonke ezweni lami.

Izinga lobuchwepheshe lobuchwepheshe be-photo-oxidative biodegradation yefilimu yepulasitiki lidlula kude izinga likazwelonke, elihambisana nezinga eliphezulu kakhulu lokucekelwa phansi kwe-polyolefin emhlabeni (PAS 9017: 2020).

Ngemva kokuxuba i-photo-oxygen biodegradable masterbatch ibe yizinsalela zepulasitiki ezifana ne-PE ne-sarin, imikhiqizo ekhiqizwayo inezinto ezibolayo, futhi izinga layo lezinsuku eziyi-180 lokuwohloka kwe-biodegradation lingafinyelela ku-60%, lihlangabezana nesilinganiso sikazwelonke se-GB/T 38082- 2019 esidingekayo.Ingacekelwa phansi ngokuphelele ngaphansi kwezimo zokulahlwa komoya ovulekile, indawo yokulahla imfucumfucu noma i-aerobic composting.# Iphepha lephepha eliboshwe nge-PE

Ubuchwepheshe be-photo-oxygen biodegradation bungaphumelela ekuhlolweni kwamazinga kazwelonke aseShayina alandelayo: GB/T 20197-2006, GB/T 19277.1-2011, GB/T 38082-2019.Ngokuhambisana nenqubomgomo yekhabhoni embaxambili yamanje nefilosofi.

Ukukhethwa Kwemizila Yobuchwepheshe Be-Biodegradation Yezingubo Ezihlukene

I-EVA enamathelayo kanye ne-PP enamathelayo ifaneleka kakhulu kubuchwepheshe benkampani yaseShayina (i-anaerobic + marine) ye-biodegradation, yebo, ubuchwepheshe benkampani yaseShayina bokungcoliswa kwe-biodegradation ye-photo-oxygen bungasetshenziswa.

I-Sarin resin, i-LLDPE, i-LDPE nezinye izigqoko zifaneleka kakhulu kubuchwepheshe be-photo-oxygen biodegradation yezinkampani zaseShayina.Yebo, kungenzeka futhi ukwehlisa izinga lokushisa elincibilikayo libe ngaphansi kuka-310 °C ukuze kube lula ukwamukelwa kobuchwepheshe (i-anaerobic + marine) yokuwohloka kwezinto eziphilayo.#Nanning Dihui Paper Products Co., Ltd.
