高分子合金修补剂是80年代新型材料之一,与一般高分子材料相比,它具有良好的耐候性、耐腐蚀性和尺寸稳定性,能进行机械加工,已广泛应用于设备、管道的堵漏和机器零部件因腐蚀、冲刷、磨损等损坏后的修复.一、几种常用高分子合金修补剂简介1.超金属修补剂是一种由高分子聚合物和含硅很高的金属粉末(有磁性,但不导电)组成的双组分材料,由于高分子聚合物能分散到金属里,与金属进行分子间反应,形成很强的分子连接键,所以,它不需加热就能很快将管道、设备及机器零部件修复好,称为冷焊或分子焊.(1)主要性能①固化速度快,24小时即可使用,性能稳定,属永久性修复;②具有较高的抗压强度、抗冲击强度,并具有一定的挠曲强度,能适应金属的热胀冷缩;③固化时不塌落,不收缩,没有重量损失,固化后可进行机械加工;④耐腐蚀性好,无毒性;⑤使用温度为—55～230℃.(2)应用范围可应用于机器零部件如轴、机壳、轴承箱
Polymer alloy repair agent is one of 80 new materials, compared with the general polymer materials, it has good weather resistance, corrosion resistance and dimensional stability, can be machined, has been widely used in equipment, pipe plug Leakage and mechanical parts due to corrosion, erosion, wear damage repair, etc. I. Introduction of several commonly used polymer alloy repair agent 1. Super metal repair agent is a polymer made of high polymer and silicon metal powder (Magnetic, but not conductive) composed of two-component material, because the polymer can be dispersed into the metal, with the metal intermolecular reaction, the formation of strong molecular link, so it can be heated Quick repair of pipes, equipment and machine parts, called cold welding or molecular welding. (1) The main performance ① fast curing speed, 24 hours to use, stable performance, is a permanent repair; ② has a higher resistance Compressive strength, impact strength, and has a certain flexural strength, can adapt to the thermal expansion and contraction of the metal; ③ curing does not collapse, no contraction, no weight loss, after curing can be machined; ④ good corrosion resistance , Non-toxic; ⑤ temperature of -55 230 ℃. (2) application may be applied to machine parts such as shafts, the housing, the bearing housing
