家具厂水性漆涂装过程VOC散发特征研究
VOC emission characteristics of water-based paint during painting process in furniture factories
摘要：
家具制造业排放的挥发性有机化合物（VOC）主要来源于涂装环节。对某家具厂涂装生产线底漆、面漆、干燥工艺废气中的VOC进行了组合采样管采样，采用气相色谱-质谱联用仪分析了其组分与浓度。结果表明，水性漆废气中VOC的主要组分为乙酸乙酯，其次是正己烷和甲苯。对比水性漆自身与涂装废气中主要VOC种类，应用主成分分析方法分析了各物性（沸点、相对分子质量、相对空气的密度、相对水的密度和运动黏度）对水性漆VOC散发的影响，结果表明，沸点为主要影响因素。
Abstract：
The volatile organic compound (VOC) emitted by the furniture manufacturing industry mainly comes from the painting process. VOC in primer, topcoat and drying process exhaust gas of a furniture factorys coating production line is sampled with combined sampling tubes, and the composition and concentration of VOC are analysed by a gas chromatography-mass spectrometry. The results show that the main component of VOC in water-based paint exhaust gas is ethyl acetate, followed by n-hexane and toluene. The main types of VOC in the water-based paint itself and the exhaust gas from painting are compared. The principal component analysis method is used to analyse the effects of various physical properties (boiling point, molecular weight, relative air density, relative water density and kinematic viscosity) on VOC emission of water-based paint. The results show that boiling point is the main influencing factor.
