【摘要】 目的了解公共场所装修后通风方式及通风时间对室内甲醛浓度、甲醛动态变化规律及其影响因素。方法选择简单装修和精装修的宾馆、招待所各3个,分别在装修后1、2、12个月对其通风前后的室内甲醛浓度进行了测量。结果甲醛浓度在装修2个月后,可以下降20%~50%;再加上通风30min后,无论是空调通风还是自然通风,室内甲醛浓度快速下降60%~80%。结论加强室内通风换气是控制甲醛浓度的有效途径。更多还原

【Abstract】 Objective To learn the effect of ventilation time and styles on the concentration and dynamic changes of formaldehyde in the indoor air of newly-decorated public places. Methods 3 finely-decorated and 3 simply-decorated hotels were selected; the concentrations of formaldehyde were measured before and after ventilation 1, 2 and 12 months after decoration. Results The concentration of formaldehyde decreased by 20%～50% 2 months after decoration; when administered with 30 minutes’ ventilation, the concentration of formaldehyde decreased by 60%～80%. Conclusion To strengthen ventilation is an effective approach to control formaldehyde concentration.更多还原
