Njengamanje, izinga lezinkomishi zephepha ezilahlwayo emakethe alilingani, ingozi efihliwe inkulu.Abanye abenzi bezinkomishi zephepha bangeza izikhanyisi ze-fluorescent ukuze zibukeke zimhlophe.Izinto ze-fluorescent zenza amangqamuzana aguquke futhi abe umdlavuza lapho esengene emzimbeni.Ukuze wenze inkomishi ingabi namanzi, ingaphakathi lendebe limbozwe ngefilimu ye-polyethylene engenamanzi.I-Polyethylene ikhemikhali ephephe kunazo zonke ekucutshungulweni kokudla, kodwa uma impahla ekhethiwe ingalungile noma ubuchwepheshe bokucubungula bungekho ezingeni, izinhlanganisela ze-carbonyl zingase zifakwe i-oxidized ngesikhathi sokuncibilika noma ukumbozwa kwe-polyethylene enkomishini yephepha, futhi izinhlanganisela ze-carbonyl aziguquguquki. kalula ekamelweni lokushisa, kodwa ingase ihwamuke lapho inkomishi yephepha igcwele amanzi ashisayo, ukuze abantu bayinuke.Nakuba zingekho izifundo zokuqinisekisa ukuthi i-carbonyl compounds ekhishwe ezinkomishini zephepha izoletha noma yikuphi ukulimala emzimbeni womuntu, kodwa kusukela ekuhlaziyweni kwethiyori evamile, ukuthathwa kwesikhathi eside kwalezi zinhlanganisela eziphilayo, kufanele kube yingozi emzimbeni womuntu.Okukhathaza kakhulu ukuthi ezinye izinkomishi zephepha ezisezingeni eliphansi ezisebenzisa i-polyethylene egaywe kabusha, enqubweni yokucubungula kabusha zizoba nezinguquko zokuqhekeka, okuholela enanini lamakhompiyutha ayingozi, ekusetshenzisweni kokufuduka kwamanzi kalula.Umbuso uvimbela ngokucacile ukusetshenziswa kwe-polyethylene evuselelwe ekufakweni kokudla, kodwa ngenxa yentengo ephansi, ezinye izimboni ezincane zokulondoloza izindleko, zisasebenzisa ngokungemthetho.
Ukuze kuzuzwe inkomishi yephepha ekukhiqizeni umphumela wokumelana namanzi, izobe ifakwe ungqimba lwefilimu ye-polyethylene engamelana namanzi odongeni lwangaphakathi.I-polyethylene iyikhemikhali ephephile uma kuqhathaniswa nokucubungula ukudla, kunzima ukuyincibilika emanzini, engeyona enobuthi, ayinambitheki.Kodwa uma impahla ekhethiwe ingeyinhle, noma ubuchwepheshe bokucubungula, ekuncibilikeni okushisayo kwe-polyethylene noma ukunamathela kunqubo yenkomishi, kungase kufakwe i-oxidized ku-carbonyl compounds.Izinhlanganisela ze-carbonyl azihwamuki kalula endaweni yezinga lokushisa, kodwa ziyahwamuka lapho izinkomishi zephepha zigcwele amanzi ashisayo, ngakho abantu banephunga elimnandi.Ukungenisa isikhathi eside kwalesi sakhi esiphilayo kuyingozi empilweni.Ezinye izinkomishi zephepha ezisezingeni eliphansi zenziwe nge-polyethylene egaywe kabusha, ezokhiqiza izinhlanganisela eziningi eziyingozi lapho kwenziwa kabusha.Umbuso uvimbela ngokucacile ukusetshenziswa kwe-polyethylene evuselelwe ekufakweni kokudla, kodwa ngenxa yentengo ephansi, ezinye izimboni ezincane zokulondoloza izindleko, zisasebenzisa ngokungemthetho.Njengamanje, izinga likazwelonke lekhwalithi yezinkomishi zephepha lidinga kuphela ukuhlola ama-microorganisms, kodwa akukho ukuhlolwa kwamakhemikhali, ngoba ukuhlolwa kuyinkimbinkimbi kakhulu futhi kunzima ukukwenza.Ezinye izinkomishi zephepha ngenxa yekhwalithi ephansi ye-pulp, imikhiqizo emhlophe yesibalo ekufakweni okukhulu kwe-fluorescent bleach, enobungozi bomdlavuza.Uphakamise ukuthi izinkomishi zephepha ezilahlwayo azikwazi ukusetshenziswa kakhulu, njengezingcono kakhulu ngamanzi abandayo, ukunciphisa ukuguquguquka kwamakhemikhali ayingozi.
