摘要
研究发现,石棉纤维具有较高的正电性,随着磨浆转数增加,其Zeta电位和电荷密度逐渐下降;在磨浆转数为1500r时,石棉胶乳抄取板的抗张强度最大,石棉纤维打浆度最大,达84°SR左右,滤水困难。CPAM/膨润土微粒助留助滤体系使纸料的打浆度有明显下降,可作为一种抄取板的助留助滤体系;APAM的加入使纸料的打浆度大幅度降低,滤水性能显著提高,是一种理想的助留助滤剂,其最佳用量为0.08%。
It was found that asbestos fiber had high positive electricity. The Zeta potential and electric charge density of asbestos dropped quickly as refining revolution increased. When the refining revolution reached 1500r, the tensile strength of asbestos latex sheets reached maximum. At this time, the beating degree of asbestos fibers also reached maximum of 84°SR, and drainability performance was difficulty. In CPAM/bentonite retention and drainage system, the beating degree of asbestos paper materials was decreased significantly, and this system could be used as retention and drainage system for sheet. Adding APAM, the beating degree of asbestos paper materials could be decreased and the drainability performance could be improved effectively, so APAM was an idealistic retention and drainage aids for the asbestos paper materials, and 0.08% was the optimal dosage.
