PENGARUH KOMPOSISI PEREKAT TERHADAP EMISI FORMALDEHIDA DAN SIFAT FISIS-MEKANIS PAPAN PARTIKEL
Jurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2017 One of the drawbacks of using particleboard bonded with urea formaldehyde (UF) is the formaldehyde emission, especially in a room with limited ventilation. Some countries have imposed restriction of allowable emission for certain
