Thaum lub sij hawm tsim cov plywood, formaldehyde-raws li adhesives feem ntau yog siv, yog li cov khoom tiav yuav tso tawm dawb formaldehyde mus rau qhov sib txawv. Thaum cov ntsiab lus pub dawb formaldehyde dhau ib qho kev txwv, nws yuav cuam tshuam rau tib neeg kev noj qab haus huv. Kev sim cov formaldehyde tso tawm ntawm plywood yog txheej txheem nyuaj. Cov qauv hauv qab no tuaj yeem siv los txiav txim siab ua ntej yooj yim ntawm formaldehyde tso tawm plywood. Ua ntej, muab cov plywood uas tsis siv nyob rau hauv ib chav me me, kaw lub qhov rooj thiab qhov rais, thiab saib nws tom qab lub sijhawm. Yog tias tsis muaj pungent tsw, nws qhia tau hais tias formaldehyde tso tawm ntawm plywood yog tsawg thiab nws siv yuav tsis cuam tshuam rau tib neeg noj qab haus huv; Yog hais tias tus ntxhiab tsw muaj zog los yog muaj qhov hnov ntxhiab, nws qhia tau tias formaldehyde tso tawm ntawm plywood yuav siab.
Hais txog qhov teeb meem formaldehyde ntawm plywood, nws cov pores sab hauv muaj qhov pore loj ntawm 0.27 thiab 0.98 nanometers thiab tau teem rau hauv cov qauv crystalline. Nws kuj muaj cov khoom hluav taws xob tsis muaj zog. Formaldehyde, ammonia, benzene, toluene, thiab xylene molecules txhua tus muaj txoj kab uas hla ntawm 0.4 thiab 0.62 nanometers thiab yog cov polar molecules, muab nws cov yam ntxwv ntawm nyiam adsorbing cov pa phem xws li formaldehyde, benzene, thiab TVOCs, yog li ua tiav cov txiaj ntsig ntawm huab cua. Nws tuaj yeem adsorb thiab decompose formaldehyde, thiab tuaj yeem rov siv dua tom qab raug tshav ntuj.
