模拟仓内温度对甲醛扩散的影响

Effect of temperature in simulation chamber on emission of formaldehyde

摘要:
目的探讨温度对甲醛扩散的影响.
方法采用0.25m³模拟仓, 分别在29, 30, 32和34℃条件下进行甲醛释放规律的研究.
结果甲醛的扩散与温度正相关.根据甲醛的扩散速度, 甲醛的扩散过程可以分为初始阶段、平缓阶段和稳定阶段.其中初始阶段甲醛的扩散速度较快, 随后趋于缓和.
结论甲醛的扩散以初始阶段为主.

Abstract:
Objective To study the effect of temperature on the emission of formaldehyde.
Methods A 0.25 m³ simulation chamber was used to investigate the emission of formaldehyde.The experiments were carried out at 29, 30, 32 and 34℃, respectively.
Results The emission of formaldehyde was positively correlated with air temperature.According to the emission speeed of formaldhyde, three different phrases can be observed during the course of the formaldehyde emission.They were initial phrase, slow emission phrase and stable phase.Quick emission of formaldehyde was observed in the initial period, then tending to decrease with time.
Conclusion The emission of formaldehyde mainly happened in the initial emission period.
