摘　　要：目前废旧电路板热解的研究很多,电路板中存在的溴化阻燃剂影响了废旧电路热解产物的回收利用。结合国内外研究现状,主要介绍了热解条件对溴迁移的影响,包括热解温度的影响、压力的影响和升温速率的影响。如果在热解过程中脱除溴,对电路板热解产物的清洁利用和环境保护有重要意义。At present, there are many researches on the pyrolysis of waste circuit boards. The brominated flame retardants in the circuit boards affect the recycling of waste circuit pyrolysis products. Combined with the current research status at home and abroad, this paper mainly introduces the influence of pyrolysis conditions on the migration of bromine. It includes the influence of pyrolysis temperature, pressure and heating rate.If the bromine is removed during the pyrolysis process, it is of great significance to the clean utilization of the pyrolysis products of the circuit board and environmental protection.
