Effect of temperature in simulation chamber on emission of formaldehyde

  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.
