摘要
通过实践摸索出提高胶版纸强度的各种方法:选择针叶浆;提高强度的化学品如抗水剂、湿强剂、干强剂、表面增强等;提高表面胶的浓度,同时降低生产成本;改变阳离子淀粉使用方法;合理控制各处缸温;提高湿部纸页干度;提高单程留着率,保证成纸的交织。
Various methods to improve the strength ofoffset printing paper were worked out through practice.The choice of the softwood pulps with good quality andthe fine flaky filler particles without sharp edges andcorners was effective in improving the surface and internal strength of paper. Various chemicals which canimprove paper strength such as water-resistance agent,wet strength agent, dry strength agent, surface-enhancedagent, etc. can also improve paper strength to some degree. Increasing the concentration of surface size caneffectively improve the surface strength of paper andreduce production costs. Changing the usage method ofcationic starch can increase the surface strength of paper.Reasonably controlling the temperature of every dryercan effectively improve paper strength and other physicalindicators. Increasing the dryness of sheet from the wetend can improve paper strength. Improving one pass retention and ensuring the good paper formation also havea great influence on paper strength.
