摘　　要：在调研长三角典型区域83家玻璃钢制品企业生产工艺、挥发性有机物(VOCs)控制技术的基础上,分析了玻璃钢制品生产过程中VOCs的来源及组分,并为玻璃钢制品企业VOCs控制提供建议。结果表明,玻璃钢制品行业VOCs主要来自于不饱和聚酯树脂等原辅料在物理加工生产过程中的易挥发组分,首要污染物为苯乙烯,其质量分数达到54.63%~86.42%,应作为玻璃钢制品行业VOCs管控的首要控制指标。长三角典型区域的玻璃钢制品生产工艺仍以手工糊制为主,建议采用机械化加工和真空导入代替手工糊制并研究降低组合工艺的成本。长三角典型区域玻璃钢制品企业采用的VOCs末端治理工艺以活性炭吸附及其组合工艺为主,处理效率虽略低于燃烧,但仍是目前该行业VOCs控制技术的最佳选择。Based on investigation of production process and volatile organic compounds(VOCs)control technologies of 83 companies producing glass fiber reinforced plastic(FRP)products in typical area of Yangtze River Delta,this study analyzed the source and components of VOCs in the production process of FRP,providing advice for FRP products industry to control VOCs.Results showed that the VOCs in the FRP industry mainly came from the volatile components of the raw and auxiliary materials such as unsaturated polyester resin(UPR)in the physical processing and production processes,and the primary component was styrene,whose mass fraction was 54.63%-86.42%.Therefore,styrene should be used as the primary control index for VOCs control in the FRP products industry.The production process of FRP products in this region was still dominated by manual paste.It was suggested that mechanized processing and vacuum introduction should replace manual paste.It was also necessary to research how to lower the cost of combination processes.The VOCs terminal treatment process adopted by the FRP companies in this region was mainly activated carbon adsorption and its combination processes.Although the treatment efficiency was a bit lower than that of combustion,it was still the most suitable choice for the VOCs control in the FRP industry.
