Mu bihe byashize, ibintu bya PFAS bisizwe hejuru y’imbere mu bikoresho bimwe na bimwe bipfunyika ibiryo bifite kanseri imwe n'imwe, ku buryo abakora ibicuruzwa byinshi bipfunyika ibiryo byihuse bahinduye gutwikira hejuru y’impapuro hamwe na plastike ya resin nka PE, PP , EVA, sarin, etc.Nyamara, mubidukikije, nka PFAS, imiterere ya molekile yiyi firime ya plastike irahagaze neza kandi ntishobora kwangirika, bityo bigatuma umwanda wa plastike wera.#PE yatwikiriye impapuro igikombe

Niyo mpamvu, amasosiyete y’Abashinwa yateje imbere kandi akora ikoranabuhanga rya biyogazi y’ifoto-ogisijeni y’ibikoresho bya polymer (nka plastiki, reberi, na fibre chimique), bishobora kugera ku myanda y’ibinyabuzima no kwangiza ifumbire.

Ifoto-ogisijeni biodegradable masterbatch nubuhanga bwa hafi bwibinyabuzima bigabanuka kwangirika byihuse mubidukikije.Kwiyongera kwa 1% birashobora kugera ku kwangirika byihuse udahinduye ibikoresho, ibikoresho byo gukora, inzira yumusaruro nibikorwa rusange byibikoresho.

Nyamara, ikiguzi cya acide polylactique gakondo PLA, PBAT, PBS, PHA nubundi buryo bwikoranabuhanga bwangiza ibinyabuzima byiyongera byibuze 100% kugeza kuri 200%, kandi imikorere yuzuye ntishobora kugera kumikorere ya plastiki gakondo, bityo ibikoresho, ibikoresho byumusaruro nibikorwa byumusaruro bigomba guhinduka.

Ifoto-ogisijeni ikoreshwa rya biodegradasiyo ya firime ya plastike nka PE na sarin irashobora gukoreshwa mugukora impapuro zipfunyitse zipfunyika ibiryo byihuse ku isoko ryUbushinwa.#PE yuzuye impapuro

Ihame rya tekiniki ya tekinoroji ya ogisijeni ikorana buhanga

Ikoranabuhanga rya plastiki ya firime yo mubushinwa ifoto-oxyde biodegradation ni ubwoko bwikoranabuhanga rishya rishingiye ku binyabuzima rishingiye kuri firime ya pulasitike yajugunywe mu bidukikije.Ikoranabuhanga ryashizweho kugirango rigumane ubuzima bwaryo bwingirakamaro nkibicuruzwa nubukanishi, ubukanishi, inzitizi, gukorera mu mucyo n’ibindi bicuruzwa mu buzima bwarwo bwose, kandi bituma firime ya plastike ibora biodegrade mu bihe bisanzwe nyuma yo kujugunywa.

Ikoranabuhanga ni ukongera ifoto-ogisijeni biodegradable masterbatch muri firime ya plastike kugirango ikore nka foto-ogisijeni biodegradable ya plastike olefin.Kunoza umuvuduko atome ya ogisijeni yinjizwa mumurongo wa polymer wa polimeri ya plastike.Polimeri ya pulasitike yacitsemo ibice bito bya molekuline mu kirere, hanyuma ikangirika na mikorobe iboneka hose mu bidukikije.#PE yometseho impapuro zo hasi

Uburyo bwo kwangirika kwa firime ya plastike ukoresheje tekinoroji ya ogisijeni ya biodegradation irashobora kugabanywamo ibice bibiri.
Icyiciro cya mbere: Filime ya plastike yongewemo nifoto-ogisijeni biodegradable masterbatch ikora hamwe na ogisijeni mu kirere, bigatuma inyongeramusaruro yibasira urunigi rwa karubone ya polymer, hanyuma umugongo wa karubone ugahinduka okiside kugirango ugire ibice bya molekile hamwe na misile ugereranije na munsi ya 10,000 cyangwa munsi yayo (Abahanga mu Burayi n’Ubuyapani bemeza ko oligomers ifite misile igereranije iri munsi ya 400.000 ishobora kumirwa na mikorobe).

Muri iki cyiciro, gutesha agaciro ni inzira ya abiotic, iteza imbere kwinjiza atome ya ogisijeni mu mugongo wa karubone aho polymer ivunika kugira ngo ikore amatsinda atandukanye akora (nka acide karubike, esters, aldehydes, na alcool).

Polimeri ndende ihindagurika kuva mumurongo wa hydrophobique macromolecule ihinduka hydrophilique ntoya ya molekile ntoya, bigatuma ibice byumunyururu wa molekile byoroha kurandurwa no gusya na bagiteri.# Umufuka wibikoresho byimpapuro

Icyiciro cya kabiri: mikorobe iboneka hose (bacteri, fungi na algae) muri kamere ibora firime ya plastike nkintungamubiri, amaherezo ikabora mo dioxyde de carbone, amazi na biyomasi.Kwangirika kuriki cyiciro byitwa inzira ya biodegradation.

Ikizamini hamwe nubuziranenge

Haba mu kirere cyangwa muri laboratoire, igipimo cyo kwangirika kw'ikoranabuhanga kirashobora kugera kuri 60%.Mu gihugu cyanjye ibipimo ngenderwaho by’igihugu GB / T 20197-2006 na GB / T 19277.1-2011, ibisabwa byo kwipimisha cyane ku gipimo cy’ibinyabuzima ni 60%.

Muri laboratoire, kuri firime zifite umubyimba uri munsi ya 15 mm, zirashobora kwinjira murwego rwibinyabuzima nyuma yo kwigana amezi 3 yo gusaza bisanzwe.Gusaza bigereranijwe birashobora guhitamo gusaza UV cyangwa gusaza itara rya xenon.

Kwinjira mu cyiciro cya biodegradation, igipimo cyambere cyo kwangirika kwa polyolefine ku isi (PAS 9017: 2020) gisaba igipimo cyo gutesha agaciro hejuru ya 90% mu minsi 730, kikaba kiri hejuru cyane y’igihugu mu gihugu cyanjye.

Urwego rwa tekiniki rwa tekinoroji-oxyde ya biodegradation ya firime ya plastike irenze kure igipimo cyigihugu, kikaba kijyanye nu rwego rwo hejuru rwo kwangirika kwa polyolefine ku isi (PAS 9017: 2020).

Nyuma yo kuvanga ifoto-ogisijeni biodegradable masterbatch mubisigazwa bya plastike nka PE na sarin, ibicuruzwa byakozwe bifite imitungo ibora, kandi igipimo cy’iminsi 180 cy’ibinyabuzima gishobora kugera kuri 60%, cyujuje ubuziranenge bw’igihugu GB / T 38082- 2019 gisabwa igipimo cy’ibinyabuzima.Irashobora kuba ibinyabuzima byuzuye mugihe cyo guta ikirere, imyanda cyangwa ifumbire mvaruganda.# PE urupapuro rwanditseho

Ifoto-ogisijeni ikoreshwa rya biodegradation irashobora gutsinda ikizamini cyibipimo byigihugu byubushinwa bikurikira: GB / T 20197-2006, GB / T 19277.1-2011, GB / T 38082-2019.Ujyanye na politiki ya karubone ibiri hamwe na filozofiya.

Guhitamo Inzira y'Ikoranabuhanga rya Biodegradation Inzira zitandukanye

Ipfunyika rya EVA hamwe na PP birakwiriye cyane kubijyanye n’ikoranabuhanga rya biodegradation ya sosiyete yo mu Bushinwa (anaerobic + marine), birumvikana ko ikoranabuhanga ry’isosiyete y’Ubushinwa ifoto-ogisijeni y’ibinyabuzima ishobora no gukoreshwa.

Sarin resin, LLDPE, LDPE nibindi bitwikiriye birakwiriye kubijyanye na tekinoroji ya ogisijeni ya biodegradasiyo ya sosiyete yo mu Bushinwa.Birumvikana ko bishoboka kandi kugabanya ubushyuhe bwashonga kugeza munsi ya 310 ° C kugirango byoroherezwe gukoresha (anaerobic + marine) tekinoroji y’ibinyabuzima.#Nanning Dihui Impapuro Ibicuruzwa Co, Ltd.
