摘要
以针叶木漂白化学热磨机械浆(BCTMP)为原料,模拟制成造纸白水,对其在生产过程中产生的溶解与胶体物质(DCS)的物理化学性能进行研究.结果表明,针叶木BCTMP所产生的溶解物质(DS)占白水中DCS的36.7%,胶体物质(CS)占白水中DCS的63.3%,其中DS是电导率的主要表现者,CS是负电荷的主要来源.利用气相色谱-质谱联用(GC-MS)对DCS中的化学组成进行了分析.
The dissolved and colloidal substances(DCS) from softwood bleached chemi-thermomechanical pulp (BCTMP) were studied on the physical-chemical properties of DCS water. The results showed that the dissolved substances (DS) contained 36.7% of the total DCS, and the colloidal substances (CS) contained other 63.3% of the total DCS. The main conductivity of DCS were from DS ,and CS mainly contributed to the cationic demand. The DCS was determined by gas chromatography-massspectrum (GC-MS) qualitatively.
