OBJECTIVE
To study the effect of humidity on emission of formaldehyde from blockboard.
METHODS
A 0.25 m3 of simulation chamber was used to explore the emission of formaldehyde from blockboard under different conditions of humidity. The temperatures of simulation chamber were kept at the degrees of 23 +/- 0.1, the velocity of ventilation of 1.0 L/min, the loading factor of (1 +/- 0.03) m2/m3.
RESULTS
The chamber concentrations of formaldehyde varied with times at the conditions of different humidities matched the hyperbolic logarithm relation. The chamber concentration of formaldehyde raised remarkably when the humidity were more than 60%. The chamber stabilization concentrations of formaldehyde varied with humidity matched the index exponent relation. Equation of curve was Y = 1.34 + 0.23e(3.30) x (R2 = 0.99).
CONCLUSION
The humidity could have an great effect on emission of formaldehyde from blockboard.
目的
研究湿度对细木工板甲醛释放量的影响。
方法
采用0.25立方米的模拟舱，探讨不同湿度条件下细木工板甲醛的释放情况。模拟舱温度保持在23±0.1摄氏度，通风速度为1.0升/分钟，装载系数为(1±0.03)平方米/立方米。
结果
不同湿度条件下模拟舱内甲醛浓度随时间变化符合对数关系。当湿度超过60%时，模拟舱内甲醛浓度显著升高。模拟舱内甲醛稳定浓度随湿度变化符合指数关系。曲线方程为Y = 1.34 + 0.23e(3.30)x（R2 = 0.99）。
结论
湿度对细木工板甲醛释放量有很大影响。
