如果油墨印刷品上残留溶剂量超过一定限度,就会使印刷品(包括印字、印花制品)相互粘结,影响质量和美观。同时,残留溶剂中的二甲苯过多,还会污染环境。而测定该残留量及分析其成分,目前还没有较好的方法。为此,我们采用气相色谱法对用油墨印刷过的塑料袋上的残留溶剂进行了定 If the residual amount of ink on the printed matter exceeds a certain limit, it will print (including printing, printing products) with each other, affecting the quality and appearance. At the same time, too much residual xylene in the solvent, but also pollute the environment. However, there is no better way to determine the residual amount and analyze its composition. For this purpose, we determined the residual solvent on the plastic bag printed with ink by gas chromatography
