随着人们对环境要求的提高,伸性纸袋纸应用更加广泛,对它的质量要求也越来越高。在生产中,关键设备采用稀释水流浆箱、伸性装置,过程采用高浓打浆后接低浓打浆工艺、上网浓度采用0.2%。优化后生产出的伸性纸袋纸各项质量指标高于国家标准,与世界一流伸性纸袋纸的质量相接近。
With the improvement of people’s requirements on environment, extensible sack paper is more widely used and its quality requirements are also getting higher and higher. In production, the key equipment adopts diluted water headbox and extensibility device. The process adopts high-concentration beating followed by low-concentration beating process, and the online concentration is 0.2%. The quality indexes of the extensible sack paper produced after optimization are higher than the national standards, which are close to the quality of the world’s leading extensible sack paper.
