本文陈述一种由聚甲基丙烯酸正了酯和异丁酯组成的氧化物阴极粘结剂。聚甲基丙烯酸树酯由于容易生产,便于控制杂质成分,所以性能稳定,且处理操作安全。它们的分解产物几乎完全解聚成气态单体,对阴极和调制极等,均无沾污。通试验证明,用甲基丙烯酸正了和异丁酯作为粘结剂的氧化物阴极初始激活容易,活性较好,寿命过程中发射稳定,衰退缓慢。此外,在工艺上所带来的优点是,阴极的涂层牢固,不易掉粉、装架时,涂层不易受损。
This article describes an oxide cathode binder consisting of polymethyl methacrylate and isobutyl methacrylate. Polymethacrylate is easy to produce, easy to control the impurity component, so the performance is stable, and the handling operation is safe. Their decomposition products are almost completely depolymerized into gaseous monomers, with no staining of the cathode and the modulating electrode. Through experiments show that, with methacrylic acid and isobutyl ester as the binder of the initial activation of the oxide cathode easy, better activity, life-span emission stability, slow decline. In addition, the process brings the advantage that the cathode coating firm, not easy to powder, the rack, the coating is not easy to damage.
