后处理措施对橡塑地板布挥发性有机物释放的影响

Effect of Aftertreatment Methods on the Volatile Organic Compounds Emissions of Rubber and Plastic Floor Covering

为优选有效降低橡塑地板布挥发性有机物(VOC)释放量的后处理措施,本研究以橡胶地板布和PVC地板布为研究对象,采用袋式法对比分析不同后处理措施——常温通风放置、烘烤后通风放置、喷涂密封剂和分解剂等对降低VOC尤其是总挥发性有机物(TVOC)释放量的效果。研究结果表明,烘烤后通风处理在地板布下线后的短期内可有效降低产品VOC;烘烤后通风放置7天后,橡胶和PVC地板布的TVOC降幅分别为82%和67%,效果明显优于其他后处理措施;采取不同后处理措施的两种地板布,通风放置30d后,TVOC降幅均能达83%以上,即采用长期常温通风处理措施即可显著降低产品VOC释放量。本研究为生产厂家优选有效降低产品VOC释放的后处理措施提供了数据支持和理论指导。

To select more effective aftertreatment on reducing the volatile organic compounds(VOC)emissions of floor covering,sampling bag method was used to evaluate the effect of different aftertreatment methods,including ventilation at ambient temperature or baking,applying a coat of sealant or decomposition agent on samples,on reducing VOC emissions,especially total volatile organic compounds(TVOC)emissions,of rubber floor covering and PVC floor covering.Experimental results show that the aftertreatment of ventilation after baking can reduce the VOC emissions of the two kinds of floor covering in a short time(7 days),with TVOC falling by 82%for rubber floor covering and 67%for PVC floor covering,significantly better than other kinds of aftertreatment.In a long term(30 days),the four kinds of aftertreatment have similar effects on reducing the VOC emissions of rubber and plastic floor covering,with TVOC falling by at least 83%.This study provides strong data support and theoretical guidance for manufacturers to select more effective aftertreatment to reduce the VOC emissions.
