Iyini i-polyvinyl alcohol (PVA)?

Ingabe i-polyvinyl alcohol iphephile?

I-PVA ivamise ukudideka ne-polyvinyl acetate (PVAc), iglue yokhuni, ne-polyvinyl chloride (PVC), into equkethe ama-phthalates nezinsimbi ezisindayo. Zontathu zingama-polymer, kodwa ziyizinto ezihluke ngokuphelele.

I-Polyvinyl alcohol iyi-polymer engenabuthi, ebolayo, futhi imikhiqizo equkethe i-PVA iphephile ukuthi isetshenziswe futhi iphephile ukusetshenziswa. I-Environmental Working Group ilinganisele njengesithako esinobungozi obuncane ezimonyoni, futhi i-Food and Drug Administration igunyaze i-PVA ukuthi isetshenziswe ekufakweni kokudla nasekufakweni kwemithi.

Ingabe i-polyvinyl alcohol iyancibilika emanzini?

Yebo, i-PVA ingancibilika ngokushesha, ngisho nasemanzini abandayo. Ngemuva kokuthi ifilimu ye-PVA incibilike, noma yiziphi izinhlobo ezingama-55 zama-microorganisms akhona ezinhlelweni zokuhlanza amanzi angcolile zingakwazi ukwephula okusele kwefilimu encibilikile.

Abanye abantu bakhathazekile ngokuthi lawa ma-microorganisms akhona yini ekugxilweni okukhulu ngokwanele ukuze aphule ngokuphelele ifilimu ye-PVA. Izindaba ezinhle ukuthi izinhlelo eziningi zamanzi angcolile ziqukethe okwanele kwalawa magciwane, ngakho-ke i-PVA ithathwa njengento ebola kalula.

Ingabe i-PVA ingumthombo we-microplastics?

Ifilimu ye-PVA ayifaki isandla ekungcolisweni kwe-microplastic noma ihlangabezane nanoma yiziphi izincazelo ze-microplastic: ayiyona i-micro- noma i-nano-size, iyancibilika emanzini kakhulu, futhi iyakwazi ukubola. Ucwaningo oluvela ku-American Cleaning Institute lubonise ukuthi okungenani amaphesenti angu-60 efilimu ye-PVA ayonakaliswa phakathi kwezinsuku ezingu-28, futhi cishe u-100% uwohloka phakathi kwezinsuku ezingu-90 noma ngaphansi.

Ingabe utshwala be-polyvinyl bubi emvelweni?

Utshwala be-Polyvinyl buklanyelwe ukuthi bukwazi ukubola ngokuphelele, futhi abuchitheki noma buqhekeke bube amaplastiki amancane nganoma isiphi isikhathi. Uma ifilimu ye-PVA incibilika futhi igeza umsele, yonakaliswa izinto eziphilayo emanzini angcolile - futhi lokho ukuphela komjikelezo wempilo we-PVA.

Kungani ngizwa abahlinzeki abaningi be-PVA njengamanje?

Abanye abathengisi bakhiphe izifundo ezingavumelani nocwaningo oluzimele mayelana notshwala be-polyvinyl, okudala ukudideka okuthile mayelana nemikhiqizo edayiswa i-JINJI nabanye abathengisi. Futhi lokho kulungile! Sifuna amakhasimende e-JINJI - kanye nabathengi bebonke - babe nelukuluku lokwazi ngezithako emikhiqizweni abayisebenzisayo. Kodwa kubalulekile ukubheka izifundo ezizimele ngaphambi kokwenza umbono wakho futhi ushintshe imikhuba yakho yokuthenga. Zihlomise ngolwazi oluvela emithonjeni enedumela elihle, engachemile ukukusiza ugweme ukukhohliswa ngokuwasha okuluhlaza - noma ukudunyazwa ukwesaba.

I-Polyvinyl alcohol kanye nemvelo

Ingabe imikhiqizo ye-JINJI iqukethe i-PVA?

I-PVA, ebizwa nangokuthi i-PVOH noma i-PVAI, iyi-polymer yokwenziwa engenambala futhi engenaphunga. Okwenza utshwala be-polyvinyl bukhetheke kakhulu ukuthi buncibilika emanzini, okuyindlela emnandi yokusho ukuthi buncibilika emanzini. Ngenxa yokuncibilika kwayo emanzini, i-PVA ivame ukusetshenziswa njengefilimu yokumboza elondolo nemishini yokugeza izitsha, kodwa futhi itholakala emikhiqizweni efana nezimonyo, ama-shampoos, amaconsi wamehlo, amaphakethe okudla okudliwayo, namaphilisi emithi.

I-JINJI RDP isebenzisa izinto ze-PVA ezincibilika ngokuphelele emanzini futhi zibola. Uma ukusabela kwe-PVA ne-VAE, izobe yoma futhi yenze impushana ye-RDP.

I-JINJI isemkhankasweni wokwenza ezinye izindlela ezivumelana nemvelo zemikhiqizo yokunakekela yasendlini nezomuntu siqu nezimonyo. Sifuna ukudala izinto ezibalulekile zasekhaya ezisekela izixazululo zemvelo kunokucekela phansi imvelo. Sisusa ukupakishwa kwepulasitiki emikhiqizweni yethu futhi senza ingxenye yethu ukuze sakhe ikusasa elizinzile.
