I-Aldehyde Scavenger — Amakhemikhali asekelwe kumakhemikhali asebenzayo e-polyamine

I-Formaldehyde (HCHO) iyi-compound e-organic eguquguqukayo engenambala, enamandla kakhulu (VOC) eyigesi ekamelweni lokushisa futhi encibilika kalula emanzini. Iyingxenye ebalulekile ekukhiqizweni kwezimboni eziningi kanye nezinqubo ze-metabolic, esetshenziswa kabanzi kulezi zinsimu ezilandelayo: ama-resin okwenziwa (njenge-urea formaldehyde resins, ama-phenolic resins), ama-adhesive, amapulasitiki, ama-textile finishing agents, njll.

I-Formaldehyde ihlukaniswa njenge-carcinogen yeQembu 1 (ngokusobala ibangela umdlavuza kubantu) yi-World Health Organization (WHO) kanye ne-International Agency for Research on Cancer (IARC), futhi izingozi zayo zibonakala kakhulu ku:
①Ukuchayeka isikhathi esifushane:
Ukucasuka: Ukuthintana ngqo kungabangela ukubomvu nokuvuvukala kwamehlo, umuzwa wokushisa emphinjeni, ukungezwani komzimba nesikhumba, njll.
Izimpawu zokuphefumula: okuholela ekukhwehleleni, ukuqina kwesifuba, ukwanda kwe-asthma, njll.
②Ukuchayeka isikhathi eside:
Ingozi Yokubangela Umdlavuza: Ukuhogela i-formaldehyde isikhathi eside kungabangela umdlavuza we-nasopharyngeal, i-leukemia, njll.
Ubuthi obungapheli: bulimaza isimiso somzimba sokuzivikela, isimiso sezinzwa, futhi buyingozi kakhulu kwabesifazane abakhulelwe, izingane kanye nabantu asebekhulile.

I-Aldehyde Scavenger yethu isetshenziselwa ukususa i-formaldehyde esele kanye ne-acetaldehyde kuma-polymer,ifaneleka kakhulu ekususeni i-acetaldehyde ku-PET ukuze ihlangabezane nezidingo zokupakisha ukudla neziphuzoIfanele futhi ukususa i-formaldehyde ne-acetaldehyde kuma-resin e-acetate, ama-adhesive, kanye nezingubo zokupenda.

I-PET (i-polyethylene terephthalate) iyinto evame ukusetshenziswa emabhodleleni eziphuzo. Ngokwethiyori, i-PET emsulwa ngokwayo ayinayo i-formaldehyde, kodwa izici ezilandelayo zingase zibangele ukuthi iqukethe inani elincane le-formaldehyde:
① I-PET ingase ibole kancane ngesikhathi sokucubungula izinga lokushisa eliphezulu (njengokuncibilikisa), okukhiqiza inani elincane le-formaldehyde.
② Ama-catalyst ensimbi asetshenziswa ekukhiqizweni kwe-PET, njengezakhi ze-antimony, angakhuthaza ukusabela okungekuhle futhi akhiqize i-formaldehyde.
③ Ezinye izinto zokufaka imibala noma izinsiza zokucubungula zingabola futhi zikhiphe i-formaldehyde ngaphansi kokushisa okuphezulu noma ukukhanya.
