一种耐脆裂的机械密封用石墨静环及其制造方法
摘要：
本发明涉及一种耐脆裂的机械密封用石墨静环及其制造方法。所述的耐脆裂的机械密封用石墨静环由金属、石墨和粘接剂组成。所述的金属为铁镍合金；石墨为碎片状柔性石墨；粘接剂可以是有机粘接胶或其他胶类。其制造工艺是将金属、石墨和粘接剂三者按规定的比例混合均匀，然后放在模具中压制成型。为了增强其强度，还可以将压制成型的石墨静环放入高温中加热固化。可以用作机械密封的静环材料。
摘要（英）：

The invention relates to a brittle-fracture-resistant graphite stationary ring for mechanical seal and a manufacturing method of the brittle-fracture-resistant graphite stationary ring. The brittle-fracture-resistant graphite stationary ring for mechanical seal is composed of metal, graphite and an adhesive. The metal is ion-nickel alloy; the graphite is fragment-shaped flexible graphite; and the adhesive can be an organic adhesive agent or other glues. The manufacturing method comprises the following steps of: uniformly mixing the metal, the graphite and the adhesive according to a specified proportion, and then, placing the mixture in a die to press for forming. In order to enhance the strength of the graphite stationary ring, the graphite stationary ring formed by pressing can be placed in a high-temperature environment and cured. The brittle-fracture-resistant graphite stationary ring for mechanical seal can be used as a stationary ring material for mechanical seal.
