摘要
低浓度、高毒性的挥发性有机化合物(VOC)污染大气,造成“病态建筑综合症(SBS)”,严重威胁着人们的身体健康。空气中的负离子除有利于人体生理健康以外,还能有效分解空气中的VOC。将一种负离子添加剂添加到墙体涂料中,可以得到一种能有效释放负离子的涂料。本文测试了涂刷负离子添加剂涂料的测试小室中负离子分解总挥发性有机化合物(TVOC)及甲醛的性能,结果证明:涂料释放的负离子能有效分解VOC,使室内VOC的浓度在较短时间内满足GB/T—18883—2002的要求。
The volatile organic compound(VOCs) with low concentration but high toxicity will pollute atmosphere and causes so-called 'Sickly Building Syndrome'(SBS),and imperil heavily the health of people.The negatively charged ions in air will be either beneficial to the health of people or decompose the VOCs in air.Incorporation of a negatively charged ion additive in coatings will effectively release negatively charged ions.This article has reported the tests of decomposition of TVOCs and formaldehyde in small chamber coated with coatings added with negatively charged ion coatings.It has shown that the negatively charged ions released can effectively decompose the VOCs and reduced down to level that meet the specification specified in standard of GB/T—18883—2002 in short time.
