摘要
纳米4A沸石广泛用于高钙废水的处理,本研究探讨了吸附Ca2+纳米4A沸石与碳酸钙复配加填对纸张性能的影响。结果表明,吸附Ca2+纳米4A沸石与碳酸钙在粒径分布和形貌特征上具有良好的匹配性。吸附Ca2+纳米4A沸石替代量在50%时,纸张的抗张指数较碳酸钙填料提高了7.4%;替代量在25%时,耐破指数提高了4.8%,环压指数提高了21.1%。吸附Ca2+纳米4A沸石表现出与纤维之间明显的交织作用,纸张纤维之间具有更好的结合度,提高了纸张的平滑度。
The effect of using blended calcium carbonate and nano-4A zeolite which has adsorbed Ca^2+ as filler on the paper strength property was studied. The results showed that nano-4A zeolite adsorbed Ca^2+ was matched with calcium carbonate on the particle size distribution and morphology features. The tensile index of the paper increased by 7.4% compared with the filler of calcium carbonate when using the blended filler and the replacement of nano-4A zeolite was 50%. Burst index increased by 4.8%, ring crush index increased by 21.1% when the replacement was 25%. There is obvious intertexture between nano-4A zeolite adsorbed Ca^2+ and fiber. The smoothness of the paper was improved when the paper fiber had better bonding. The application of nano-4A zeolite adsorbed Ca^2+ could reduce the concentration of Ca^2+ in effluent of the paper mill. It was good for wastewater treatment and recycling.
