Abstract:
Objective To explore the effects of environmental factors such as temperature, relative humidity and ventilation rate on release quantity of formaldehyde in woodiness boards. Methods A small climate chamber was employed to control the temperature, concentration of vapor and ventilation rate. The quantity of formaldehyde released from woodiness boards was determined by 4160 Formaldehyde Analyzer of INTERSCAN. Results The released quantity of formaldehyde increased from 0.12 mg/(m2?h) to 0.35 mg/(m2?h) as the temperature increased from 18 ℃ to 38 ℃, it increased from 0.20 mg/(m2?h) to 0.46 mg/(m2?h) as the concentration of vapor increased from 3.99 mg/L to 15.75 mg/L, it increased from 0.21 mg/(m2?h) to 0.62 mg/(m2?h) as the ventilation rate increased from 0.5 h-1 to 2.0 h-1. Conclusion The emission rate of formaldehyde in woodiness boards will be accelarated when the temperature, concentration of vapor and ventilation rate increased.
