摘要： A carbonaceous material is fabricated by kneading of carbon powder and a binder. A particle diameter of the carbonaceous material is adjusted after the fabricated carbonaceous material is granulated. A brush material is fabricated by mixing of the carbonaceous material of which the particle diameter is adjusted and metal powder. A brush is completed by forming and thermal processing of the fabricated brush material. In this case, the particle diameter of the carbonaceous material is adjusted in a constant range before the carbonaceous material and the metal powder are mixed such that an average particle diameter of the carbonaceous material in the brush is not less than 300 µm and not more than 2000 µm. Alternatively, a ratio of the volume of the carbonaceous material having the particle diameter of not less than 300 µm to the volume of the brush is adjusted to not less than 50%.

摘要翻译： 通过捏合碳粉和粘合剂来制造碳质材料。 在制造的碳质材料造粒后，调节碳质材料的粒径。 通过混合调整粒径的碳质材料和金属粉末来制造刷子材料。 通过对制成的刷子材料的成形和热处理来完成刷子。 在这种情况下，碳质材料的粒径在碳质材料和金属粉末混合之前被调节到一定的范围，使得刷子中的碳质材料的平均粒径不小于300μm并且不大于 2000μm。 或者，将粒径不小于300μm的碳质材料的体积与刷子的体积的比率调整为不小于50％。
