Method for improving quality of piezoelectric ceramic buzzing piece
The invention discloses a method for improving the quality of a piezoelectric ceramic buzzing piece and belongs to a preparation method of the piezoelectric ceramic buzzing piece. The invention aims to provide the preparation method of the piezoelectric ceramic buzzing piece to meet the requirement of large-scale production and improve the product quality. The preparation method comprises the following steps: preparing slurry, molding a green body, sintering the green body, coating a silver electrode, and pasting: uniformly mixing piezoelectric ceramic powder and polyvinyl alcohol colloid, spraying and drying to obtain aggregates; putting the aggregates into a mold, pressing into a bar green body by adopting an isostatic pressing process, and sintering; grinding an outer circle of a piezoelectric ceramic rod body, and then cutting the piezoelectric ceramic rod body into slices; ultrasonically cleaning, drying, printing silver paste on a surface, and burning silver; and bonding a coatedsilver electrode piezoelectric ceramic sheet with the metal sheet, and performing drying and curing. The buzzing sheet prepared by the method has the advantages of small impedance, large capacity, small frequency drift amount and the like, and the method is a method for preparing the piezoelectric ceramic buzzing sheet.
本发明公开了一种提高压电陶瓷蜂鸣片质量的方法，属于压电陶瓷蜂鸣片制备方法；旨在提供一种既能满足大规模生产的需求、又可提高产品质量的压电陶瓷蜂鸣片制备方法。它包括制备浆料、生坯成型、生坯烧结、银电极被覆、贴片：将压电陶瓷粉体与聚乙烯醇胶体混合均匀，喷雾、干燥，得到团粒；团粒装入模具中，采用等静压工艺压制成棒料生坯，烧结；磨削压电陶瓷棒体外圆，然后将其切割成薄片；超声清洗、烘干，表面印刷银浆，烧银；被覆银电极压电陶瓷片与金属片粘合，烘干固化。本发明方法制备的蜂鸣片具有阻抗小、容量大频率飘逸量小等优点，是一种至制备压电陶瓷蜂鸣片的方法。
