针对某公司一涂装车间采用的水性3C2B工艺,通过实施一系列降低VOC排放的技术及精益管理措施,如烤炉废气焚烧、回收清洗溶剂、取消内装中涂、小泵系统生产、减少换色次数等,将VOC的排放量控制在20 g/m2以内,远小于工业涂装清洁生产标准中的1级排放标准35 g/m2.该排放指标处于国内领先排放控制水平.
Taking a waterborne 3C2B process of a company as the example,this paper discusses a series of technologies and related regulation for reduction of VOC in coating workshop.These measures include burning of oven exhaust gas,recycling of washing solvent,elimination of inter-coat,utility of small pump system and reduction of times for color change,etc.Thus,the emission of VOC is controlled less than 20 g/m2,which is far less than the parameter described in the industrial standard of cleaner production and shows an outstanding level in China.
