Aldehyde Scavenger — Mankhwala opangidwa ndi mankhwala a polyamine

Formaldehyde (HCHO) ndi chinthu chopanda utoto, chopweteka kwambiri komanso chopanda mphamvu chomwe chimakhala ndi mpweya kutentha kwa chipinda ndipo chimasungunuka mosavuta m'madzi. Ndi chinthu chofunikira kwambiri pakupanga mafakitale ambiri komanso njira zamagetsi, chomwe chimagwiritsidwa ntchito kwambiri m'magawo otsatirawa: ma resini opangidwa (monga ma resini a urea formaldehyde, ma resini a phenolic), zomatira, mapulasitiki, zomaliza nsalu, ndi zina zotero.

Formaldehyde imayikidwa m'gulu la gulu 1 la khansa (yomwe imayambitsa khansa kwa anthu) ndi World Health Organization (WHO) ndi International Agency for Research on Cancer (IARC), ndipo zoopsa zake zimawonekera makamaka mu:
①Kuwonekera kwa kanthawi kochepa:
Kukwiya: Kukhudza mwachindunji kungayambitse kufiira ndi kutupa kwa maso, kutentha pakhosi, ziwengo pakhungu, ndi zina zotero.
Zizindikiro za kupuma: zomwe zimapangitsa kuti munthu ayambe kukokera, kufinya chifuwa, kukulirakulira kwa mphumu, ndi zina zotero.
②Kuwonekera kwa nthawi yayitali:
Kuopsa kwa khansa: Kupuma formaldehyde kwa nthawi yayitali kungayambitse khansa ya m'mphuno, khansa ya m'magazi, ndi zina zotero.
Kuopsa kwa matenda: kumawononga chitetezo chamthupi, mitsempha, ndipo kumavulaza kwambiri amayi apakati, ana, ndi okalamba.

Chotsukira chathu cha Aldehyde chimagwiritsidwa ntchito kuchotsa formaldehyde yotsalira ndi acetaldehyde kuchokera ku ma polima,yoyenera kwambiri kuchotsa acetaldehyde kuchokera ku PET kuti ikwaniritse zofunikira pakulongedza chakudya ndi zakumwaNdi yoyeneranso kuchotsa formaldehyde ndi acetaldehyde kuchokera ku ma acetate resins, zomatira, ndi utoto.

PET (polyethylene terephthalate) ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri popanga mabotolo a zakumwa. Mwachidule, PET yoyera yokha ilibe formaldehyde, koma zinthu zotsatirazi zingayambitse kukhala ndi formaldehyde yochepa:
① PET ikhoza kuwonongeka pang'ono panthawi yokonza kutentha kwambiri (monga kusungunuka kwa madzi), ndikupanga kuchuluka kochepa kwa formaldehyde.
② Zinthu zoyambitsa zitsulo zomwe zimagwiritsidwa ntchito popanga PET, monga mankhwala a antimoni, zimatha kuyambitsa zotsatira zoyipa ndikupanga formaldehyde.
③ Zinthu zina zopaka utoto kapena zothandizira kukonza zinthu zimatha kuwola ndi kutulutsa formaldehyde kutentha kwambiri kapena kuwala.

Lumikizanani nafe! Tidzayankha mkati mwa maola 48.
