建筑胶黏剂使用VOCs排放系数与排放清单

Emission Inventory and Emission Factors of Volatile Organic Compounds(VOCs)from Architectural Adhesives

建筑装饰是我国VOCs重要人为排放源之一,关于建筑胶黏剂VOCs排放相关研究极少.本文以建筑胶黏剂为研究对象,通过实测获取各类建筑胶黏剂VOCs含量水平和排放系数,采用排放系数法,自上而下建立了我国2013~2017年建筑胶黏剂VOCs排放清单.结果表明,建筑胶黏剂使用VOCs综合排放系数为97 kg·t^-1,其中溶剂型、水基型和本体型建筑胶黏剂的VOCs排放系数分别为543、45和63 kg·t^-1;2013~2017年我国建筑胶黏剂使用VOCs排放量分别为16.5、18.1、18.8、20.1和21.9万t.水基型、本体型和溶剂型建筑胶黏剂的VOCs排放量贡献分别为25.5%、23.6%和50.9%;2017年山东、江苏、浙江、四川、广东、河南、云南和福建等8省贡献较大,排放量合计为12.0万t,占全国建筑胶黏剂VOCs排放量的约55%.

Architectural decoration is an important anthropogenic emission source of VOCs in China,and there are few studies on the emission of VOCs from architectural adhesives.In this study,the VOCs content level and emission factors of various architectural adhesives were measured and then,a VOC emission inventory of architectural adhesives in China from 2013 to 2017 was established by a top-down emission factor method.Results showed that the comprehensive VOCs emission factor of architectural adhesives was 97.0 kg·t^-1,of which 543 kg·t^-1 was from solvent-based architectural adhesives,45 kg·t^-1 was from water-based architectural adhesives,and 63 kg·t^-1 was from bulk architectural adhesives.The VOCs emissions from architectural adhesives were 165 kt,181 kt,188 kt,201 kt,and 219 kt from 2013 to 2017 in China.The contribution of VOCs emission of various disparate architectural adhesives was 25.5%,23.6%,and 50.9%for water-based,bulk,and solvent-based types,respectively.Shandong,Jiangsu,Zhejiang,Sichuan,Guangdong,Henan,Yunnan,and Fujian provinces contributed significant amounts,with a total emission of 120 kt in 2017,accounting for nearly 55%of the total VOCs emission for architectural adhesives.
