Lightning arrester resistor disc manufacturing method
The invention discloses a lightning arrester resistor disc manufacturing method, which comprises: S1, selecting raw materials, taking out zinc oxide and additives in the raw materials, adding the additives into a ball milling tank, carrying out ball milling mixing, drying and crushing, loading the obtained mixture into a corundum-mullite sagger, calcining for 0.5-2 h at a temperature of 750-850 DEG C, naturally cooling, and crushing to obtain the lightning arrester resistor disc, forming additive powder; s2, sequentially putting the additive of the powdery mixture prepared in the S1 and zinc oxide into a stirring container, stirring, adding an organic binding agent, a dispersing agent and water, stirring the raw materials at 200-400 revolutions per minute to form slurry with uniform texture, granulating the slurry, and pressing into a zinc oxide resistor disc green body; according to the method, the additive can be added into the raw materials, so that the dosage of zinc oxide is reduced, the performance of the resistor disc can be improved, and the production cost is reduced.
本发明公开了一种避雷器电阻片制造方法，包括以下步骤：S1：选取原料，然后将原料中的氧化锌和各添加剂取出，将各添加剂加入到球磨罐经过球磨混合、烘干、粉碎后，得到的混合物装入刚玉莫来石匣钵中，在750℃～850℃下煅烧0.5h～2h后自然冷却、粉碎，形成添加剂粉末；S2：然后将S1制备的粉末状混合物的添加剂与氧化锌依次放置在搅拌容器中，进行搅拌，且加入有机结合剂、分散剂和水，然后再200‑400转/分下，进行对原料搅拌，形成质地均匀的浆料，然后将浆料进行造粒后压制成氧化锌电阻片生坯。通过本方法，可以通过向原料中加入添加剂，从而降低氧化锌的用量，且可以提高电阻片的性能，降生产成本。
