Aldehyde Scavenger — Cov tshuaj lom neeg raws li cov tshuaj polyamine nquag

Formaldehyde (HCHO) yog ib qho tsis muaj xim, muaj zog heev volatile organic compound (VOC) uas yog ib qho roj ntawm chav tsev kub thiab yooj yim soluble hauv dej. Nws yog ib qho tseem ceeb nruab nrab hauv ntau yam kev lag luam thiab cov txheej txheem metabolic, siv dav hauv cov teb hauv qab no: cov khoom siv hluavtaws (xws li urea formaldehyde resins, phenolic resins), adhesives, plastics, textile finishing agents, thiab lwm yam.

Formaldehyde raug cais ua Pawg 1 carcinogen (ua rau tib neeg mob qog nqaij hlav) los ntawm Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv (WHO) thiab Lub Chaw Haujlwm Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kab Mob Cancer (IARC), thiab nws cov kev phom sij feem ntau pom tseeb hauv:
①Kev raug mob luv luv:
Kev Khaus: Kev sib cuag ncaj qha tuaj yeem ua rau liab thiab o ntawm lub qhov muag, kub hnyiab hauv caj pas, ua xua rau daim tawv nqaij, thiab lwm yam.
Cov tsos mob ntawm kev ua pa: ua rau hnoos, mob hauv siab, ua rau mob hawb pob zuj zus, thiab lwm yam.
② Kev raug mob ntev:
Kev pheej hmoo mob qog noj ntshav: Kev nqus pa formaldehyde mus ntev yuav ua rau mob qog noj ntshav hauv nasopharyngeal, leukemia, thiab lwm yam.
Kev lom mus ntev: ua rau lub cev tiv thaiv kab mob, lub paj hlwb puas tsuaj, thiab tshwj xeeb tshaj yog rau cov poj niam cev xeeb tub, menyuam yaus, thiab cov neeg laus.

Peb cov Aldehyde Scavenger siv los tshem tawm cov formaldehyde thiab acetaldehyde seem ntawm cov polymers,tshwj xeeb tshaj yog tsim rau kev tshem tawm acetaldehyde ntawm PET kom ua tau raws li qhov yuav tsum tau ua ntawm cov khoom noj thiab dej haus ntim khoomNws kuj tseem tsim nyog rau kev tshem tawm formaldehyde thiab acetaldehyde ntawm acetate resins, adhesives, thiab xim pleev xim.

PET (polyethylene terephthalate) yog ib yam khoom siv feem ntau siv rau cov fwj dej haus. Hauv kev xav, PET ntshiab nws tus kheej tsis muaj formaldehyde, tab sis cov hauv qab no yuav ua rau nws muaj cov formaldehyde me me:
① PET yuav raug rhuav tshem ib feem thaum lub sijhawm ua haujlwm kub siab (xws li yaj extrusion), tsim cov formaldehyde me me.
② Cov hlau catalysts siv rau hauv kev tsim cov PET, xws li cov tshuaj antimony, yuav txhawb nqa cov tshuaj tiv thaiv sab thiab tsim cov formaldehyde.
③ Qee cov xim lossis cov khoom siv ua haujlwm yuav lwj thiab tso tawm formaldehyde thaum kub lossis raug lub teeb.
