Molding method of zeolite molecular sieve powder
The invention relates to a zeolite molecular sieve powder forming method, and belongs to the technical field of molecular sieve material preparation. The method is characterized in that a mixture containing to-be-formed powder, a macromolecular adhesive and a dispersing agent is subjected to aging, compression forming, curing and the like before carbonization. Through aging and compression molding, air contained in a mixture, especially in pore channels of the zeolite molecular sieve, is fully discharged, and the high-molecular adhesive is fully contacted with the zeolite molecular sieve powder; and through curing, the intermolecular connection of the high-molecular adhesive is tighter. The operation is beneficial for obtaining a zeolite molecular sieve forming body with a complete structure and high strength. The powder forming process provided by the invention is simple and convenient to operate, and is easy to realize in different-scale molecular sieve material preparation processes such as experimental research and industrial production.
本发明涉及一种沸石分子筛粉体成型方法，属于分子筛材料制备技术领域。其特点在于，将含有待成型粉体、高分子黏结剂、分散剂的混合物在炭化前经陈化、压缩成型、固化等步骤处理。通过陈化、压缩成型，促使包藏在混合物中、尤其是沸石分子筛孔道中的空气充分排出，高分子黏结剂与沸石分子筛粉体充分接触；通过固化，促使高分子黏结剂分子间连结更加紧密。上述操作有助于得到结构完整、强度高的沸石分子筛成型体。本发明所提供的粉体成型过程操作简便，在实验研究及工业生产等不同规模的分子筛材料制备过程中均容易实现。
