摘要
甲醛是室内空气主要污染物之一,也是装修材料需要重点监控的有害物质。本文结合检测过程中遇到的问题,进行了不同检测条件下的游离甲醛显色试验,通过试验对原有方法进行改进,并从中找出最优的试验方法。优化的试验方法已在新编制的《建筑防火涂料有害物质限量及检测方法》(JG/T 415-2013)中被采用。
Formaldehyde is one of the main hazardous pollutants for indoor air quality upon the national standard. Since then it is also the key substance need to be monitored for constructrual materials. According to the problems we met using current method, we operated a series of free formaldehyde chromogenic experiment under different conditions to optimize current approach.The best solution we found has now been adopted in the new standard 《Limit and test method of harmful substances in fier-retardant coating》JG/T415-2013.
