Determination of formaldehyde and TVOC emission factor from wood-based composites by small chamber method

摘要

This paper assesses the reproducibility of testing formaldehyde and TVOC emissions from wood-based composites such as medium density fiberboard (MDF), particleboard (PB), laminate flooring, and engineered flooring using desiccator, perforator and 20 L small chamber methods. According to desiccator and perforator standards, the formaldehyde emission level of each flooring was <= E-1 grade. The formaldehyde emission of MDF and PB was 3.48 mg/L PB and 5.38 mg/L by the desiccator method, and 8.57/100 g and 10.21/100 g PB by the perforator method, respectively.
