摘要: 本论文使用硅溶胶和磷酸二氢镁作为沸石分子筛造球的粘结剂，研究其加入量对分子筛原粉造球强度的影响。研究结果表明，两者浓度越大所造球的强度越大，磷酸二氢镁的造球效果远远好于以硅溶胶为粘结剂所制得的产物，而且价格低廉，是实验首选。当磷酸二氢镁加入量为6 mL/g，并做成球形，产品的强度则会达到最大高度5.7 m，达到分子筛的强度要求。
Abstract: In this paper, silica sol and magnesium dihydrogen phosphate were used as the binder for zeolite molecular sieves to study the influence of the addition amount on the strength of molecular powder. The results show that the greater the concentration is, the greater the strength of the ball is, and the effect of magnesium dihydrogen phosphate is much better than that of silica sol as binder. When the content of magnesium dihydrogen phosphate is 6 mL/g and has been made into spherical, the strength of the product will reach the maximum height of 5.7 m, reaching the strength requirement of the molecular sieve.
