Aldehyde Scavenger — Kemịkalụ dabere na ihe ndị na-arụ ọrụ na polyamine

Formaldehyde (HCHO) bụ ihe na-agbanwe agbanwe nke na-enweghị agba, nke na-esi ike nke ukwuu (VOC) nke bụ gas n'ọnọdụ okpomọkụ ụlọ ma dịkwa mfe ịgbaze na mmiri. Ọ bụ ihe dị mkpa n'ọtụtụ mmepụta ụlọ ọrụ na usoro metabolic dị ndụ, nke a na-ejikarị eme ihe n'ọhịa ndị a: resin sịntetik (dịka resin urea formaldehyde, resin phenolic), ihe nrapado, plastik, ihe ndị na-emecha ákwà, wdg.

Òtù Ahụ Ike Ụwa (WHO) na Òtù Mba Nile Maka Nnyocha Ọrịa Kansa (IARC) kewara Formaldehyde dị ka ọrịa kansa nke otu 1 (nke doro anya na ọ na-akpata kansa nye ụmụ mmadụ), ihe egwu ya na-apụtakarịkwa ìhè na:

A na-eji Aldehyde Scavenger anyị ewepụ formaldehyde na acetaldehyde fọdụrụ na polymers,ọ dị mma nke ukwuu iji wepụ acetaldehyde na PET iji mezuo ihe achọrọ maka nkwakọ ngwaahịa nri na ihe ọṅụṅụỌ dịkwa mma iwepụ formaldehyde na acetaldehyde site na resin acetate, ihe mgbakwụnye, na ihe mkpuchi agba.

PET (polyethylene terephthalate) bụ ihe a na-ejikarị eme karama ihe ọṅụṅụ. N'echiche, PET dị ọcha n'onwe ya enweghị formaldehyde, mana ihe ndị a nwere ike ime ka o nwee obere formaldehyde:
① PET nwere ike ịgbawa akụkụ ụfọdụ n'oge nhazi okpomọkụ dị elu (dịka mmịpụta agbaze agbaze), na-emepụta obere formaldehyde.
② Ihe ndị na-akpali ígwè e ji emepụta PET, dịka ihe ndị na-egbochi antimony, nwere ike ịkwalite mmeghachi omume n'akụkụ ma mepụta formaldehyde.
③ Ụfọdụ ihe na-agba agba ma ọ bụ ihe na-enyere aka nhazi nwere ike ịgbaze ma wepụta formaldehyde n'okpuru oke okpomọkụ ma ọ bụ ìhè.
