摘要/Abstract

摘要： 研究了不同添加剂对废旧印刷线路板非金属组分(NMFs)中树脂分离物热解脱溴的影响,结果表明,以尿素为添加剂可以促使NMFs树脂分离物中含溴阻燃剂以HBr、溴甲烷和溴乙烷的形式脱除,同时,使热解油中苯酚和其他酚类物质的含量增加,而固体残碳中的溴含量减少;对对'-二氨基二苯甲烷对废旧印刷线路板NMFs树脂分离物中含溴成分的脱除无促进作用,但可使热解油中苯酚和其他酚类物质的含量增加,同时使生成的气体量减少,液体和固体产物量增加;六亚甲基四胺尽管可以促使NMFs树脂分离物中含溴阻燃剂以HBr和溴甲烷、溴乙烷的形式脱除,但显著降低了热解油中苯酚和其他酚类物质的含量,同时有较多的N-甲基乙酰胺和N,N-二甲基甲酰胺生成,此外使得液体和固体产物量增加,但气体产物量减少。

Abstract: Influence of various additives on pyrolysis-debromination of resin in non-metal components(NMFs)in wasted printed circuit boards(WPCB)was investigated.The results show that urea additive can effectively promote removal of Br-containing flame retardant and the formation of gas phase HBr,bromomethane and bromoethane,increase amount of phenol and its derivative in pyrolysis-residue oil; and reduce amount of Br content in solid residue C.However,for DDM(4,4'-diaminodiphenylmethane)additive,although it can promote formation of phenol and its derivative,decrease gas products and increases liquid and solid products,it can not remove Br in NMFs resin of WPCB.For hexamethylenetetramine,in spite of removing Br-containing flame retardant and forming gas phase products such as HBr,methyl bromide,and ethyl bromide,decreases obviously liquid products such as phenol and its derivative,but find large amount of N-methylacetamide and N,N-dimethylformamide in liquid products.Besides,hexamethylenetetramine makes amount of liquid and solid products increase and that of gas products decrease.
