Mu kiseera ky’okukola plywood, okutwalira awamu ebisiiga ebisinziira ku formaldehyde-bikozesebwa, kale ekintu ekiwedde kijja kufulumya formaldehyde ow’obwereere ku diguli ez’enjawulo. Ekirungo kya formaldehyde eky’obwereere bwe kisukka ekkomo erigere, kijja kukosa obulamu bw’omuntu. Okugezesa okufulumya formaldehyde mu plywood nkola nzibu. Enkola eno wammanga esobola okukozesebwa okukola okusalawo okwangu okusooka ku kufulumya formaldehyde mu plywood. Sooka, tuuma plywood ezitakozesebwa mu kasenge akatono, ggalawo enzigi n’amadirisa, era weetegereze oluvannyuma lw’ekiseera. Singa tewabaawo kawoowo akawunya, kiraga nti okufulumya formaldehyde mu plywood kutono era okukikozesa tekijja kukosa bulamu bwa muntu; singa akawoowo kaba ka maanyi oba nga wabaawo okukutuka, kiraga nti okufulumya formaldehyde mu plywood kuyinza okuba okungi.
Ku nsonga ya formaldehyde eya plywood, obutuli bwayo obw’omunda bulina obunene bw’obutuli wakati wa nanometers 0.27 ne 0.98 era nga busengekeddwa mu ngeri ya crystalline. Era erina eby’amasannyalaze ebinafu. Molekyulu za formaldehyde, ammonia, benzene, toluene, ne xylene zonna zirina dayamita wakati wa 0.4 ne 0.62 nanometers era nga molekyo za polar, ekigiwa engeri y’okusinga okunyiga ggaasi ez’obulabe nga formaldehyde, benzene, ne TVOCs, bwe kityo ne kituuka ku kikolwa ky’okulongoosa empewo ey’omunda. Kisobola okunyiga n’okuvunda formaldehyde, era kisobola okuddamu okukozesebwa oluvannyuma lw’okubeera mu musana.
