模拟白水循环抄造纸页,对比白水的浓度和循环次数对浆料滤水性、留着率、纸张强度以及灰分的影响。结果表明:随着白水浓度增加,浆料滤水性略有增大、留着率相对降低,成纸的抗张指数较为稳定并略有增大,灰分增加;随着白水循环次数增加,成纸的抗张指数逐渐增大,灰分逐渐降低。 Simulated white water cycle Papermaking paper, the concentration of white water and the number of cycles on the slurry drainage, retention, paper strength and ash. The results showed that with the increase of the concentration of white water, the water filtration capacity of the slurry slightly increased, the retention rate decreased relatively, the tensile index of the paper became stable and slightly increased, and the ash content increased. As the number of white water cycles increased, The tensile index gradually increased, the ash gradually decreased.
