探究室内甲醛释放规律及茶叶水对其吸收效果

Explore the formaldehyde release law and the effect of tea water on its absorption

本文以一装修完成两年的居民房进行研究,通过控制通风和闭窗时间,探究客厅、主卧室、婴儿房的甲醛变化规律,并选择不同种类、浓度的茶叶水,讨论其对甲醛气体的去除效果。结论:闭窗6 h后室内甲醛浓度上升至最高值并趋于稳定;通风口相对的房间布局更有利于甲醛的扩散;浓度为5g/L的茶叶水的甲醛吸收效果最优,吸收率可达85.5%。建议:对于刚装修不久的相似居民住宅,建议每隔6小时通风一次;茶叶水对甲醛气体具有一定的吸收效果,可选择茶叶水擦拭装修材料来降低甲醛浓度。

This paper studies Hie change rule of formaldehyde in living room, main bedroom and infent room by controlling ventilation and window closing time, and chooses diflEBrent kinds and concentration of tea water to discuss the removal effect of formaldehyde gas. Conclusion： the concentration of formaldehyde in the room rises to the highest and tends to be stable after 6 h closed; The relative room layout of air vents is more conducive to the difiEusion of fonnaldchyde. The fommldehyde absorption of tea water with concentration of 5g /1 was optimal, and the absorption rate was up to 85,5 %. Suggestion： for similar residential buildings soon after decoration, it is suggested to be ventilated every 6 hours, The tea water has certain absorption effect to the formaldehyde gas, can choose the tea water to wipe the decoration material to reduce the fonnaldehyde concentration.
