摘 要: 利用多种化学方法和现代仪器分析手段对以美国进口旧报纸、旧杂志纸和马尾松磨木浆或化学热磨机械浆为原料抄造新闻纸的新闻纸机干燥部胶粘物的化学组分进行了分离和分析,确定了化学组分的归属和含量。结果表明,来源于废纸浆的聚醋酸乙烯酯和聚丙烯酸脂类是形成胶粘物的重要组分,同时也包含较大比例的残余油墨和无机成分。 The chem ical components of stickies/deposits on dry section of newsprint machine were separated and analyzed by using various chemical and instrumental analysis meth ods.The main materials of the stickies were identified as poly vinyl acetate an d poly acrylate from DIP.At the same time ,there were a lot of ink residuals and inorganic components in the deposits.
