废纸回用过程中硅藻土对白水中DCS的影响研究
Effect of Diatomite on DCS in White Water during the Process of Waste Paper Recycling
摘要
Abstract
With the increasing of waste paper recycling degree in papermaking industry,more attention was paid on how to solve resin trouble and stickies rouble effectively in the process of second fiber utilization industry.Diatomite was selected to be used as resin adsorbent in waste paper system.The effect of diatomite on dissolved and colloidal substances(DCS)accumulation in white-water,pulp drainage and paper performance was investigated.The improvement of diatomite on resin trouble was analyzed as well.Results showed that the addition of diatomite as resin adsorbent can relieve DCS accumulation and resin trouble effectively in waste paper recycling process.Under the help of diatomite,the drainage time was reduced about 25.8 % and the effect of retention and drainage was improved greatly.As for the paper sheet property,the ash and brightness were increased 9.13 % and 5.30 % respectively.The break length and sizing degree were reduced 14.43% and 18% respectively,but it can still meet the requirement of customers.关键词
