摘要
GB 4287-2012《纺织染整工业水污染物排放标准》中苯胺的限值,有些染整企业时常不能达标,主要原因是在聚氨酯涂层和染色工艺中选用含有MDI涂层剂和含有苯胺的染料,指明了这个关键所在,并详细列出含苯胺的染料和MDI的有害性。
Some dyeing enterprises often could not meet the aniline limits of GB 4287-2012 ＂Discharge standards of water pollutants for dyeing and finishing industry＂. The main reason is the choice of coating agent containing MDI and aniline dye in polyurethane coating and dyeing process. The key was pointed out, and the harm of aniline dye and MDI were detailly listed.
