Keeb kwm, lub thawv khoom plig ntoo (tshwj xeeb tshaj yog cov khoom siv ntoo xws li MDF, plywood, thiab fiberboard) tuaj yeem ua rau muaj kev nyab xeeb vim muaj kuab paug formaldehyde. Cov nplaum uas siv los tsim cov ntaub ntawv no (xws li urea-formaldehyde resin) muaj cov qib siab dawb formaldehyde, uas yooj yim nqus los ntawm cov zaub mov thiab tuaj yeem ua rau qhov muag, qhov ntswg, caj pas, thiab kab mob ua pa sab saud. Cov neeg tau txais kev pabcuam raug qhia kom tsis txhob yuav cov khoom noj khoom haus ntim rau hauv cov thawv ntoo uas tau tsim thiab muab pov tseg tam sim tom qab siv.
Nrog rau cov kev cai ib puag ncig nruj zuj zus, kev lag luam tam sim no tau tsom ntau dua rau cov ntaub ntawv thiab cov txheej txheem. Ib puag ncig tus phooj ywg lub thawv ntim khoom yog tsim los ntawm cov ntoo ntuj, ua tib zoo sanded thiab polished, uas ua rau muaj kev ua kom zoo dua qub thiab zoo dua qub. Nws kuj tseem pom zoo kom ua qhov tseem ceeb rau cov tuam txhab lag luam uas siv cov xim pleev xim rau ib puag ncig thiab ua tau raws li cov qauv ntawm ib puag ncig. Kev loj hlob ntawm kev paub txog ib puag ncig tau ua rau cov khoom ntim ntoo ntau nrhiav tom qab.
