室内大型喷绘VOC污染实验研究

Experimental Research on Contaminated Issues of VOC from Large Paintings Indoor

会议室和展览大厅内等经常会使用到室内大型喷绘,但大面积喷绘在室内会成为挥发性有机物的临时发生源,造成严重室内空气污染。模拟室内条件,获得喷绘的TVOC浓度变化规律,发现在2 h内,浓度可由0.1 mg/m^3上升到1.651 mg/m^3,20 h达到最大值8.5 mg/m^3,并测试了通风和几种治理剂对喷绘散发的VOC的效果,实验表明有效通风可以大幅度减少TVOC,同时,含有负离子粉和TiO_2粉的2号治理剂能较为有效地清除VOC。为喷绘污染的预防和治理做出初步研究。

The large paintings usually been placed in the meeting rooms or showing room as an advertisement or imformation transfering media,but painting with large proption will be a temporary source of volatile organic and cause serious indoor air pollution.This artical simulate the indoor condition and obtain the changing rules of concentration,and discover that the concentration can raise from 0.1mg/m^3 to 1.51 mg/m^3 in 2 hours and reach the maximum of 8.5 mg/m^3 in 20 hours.The effect of aeration and 5 kinds of curation reagent have been tested and comes a conclusion：aeration can significantly reduce the VOC,the No.2 reagent which contain and TiO_2 powder can eliminate the VOC comparing to the other.The article make a pilot study of the preventing and tratment for pollution from Painting.
