铸型尼龙(MC尼龙)是一种新型工程塑料。我国从六十年代以来,日趋广泛地将其用来代替铜和其它金属,制成机器里的耐磨、密封、传动等零、部件。铸型尼龙具备如下优良特性。 1.机械强度较高,虽然其基本特性与尼龙6相似,但由于分子量比尼龙6高1.5～2倍,因而物理、机械性能也相应提高,结晶度高,不发生内应变。 Mold nylon (MC nylon) is a new type of engineering plastics. Since the 1960s, our country has increasingly used it instead of copper and other metals to make zero, parts, such as wearable, sealed, and driven gears in machines. Cast nylon has the following excellent features. 1. High mechanical strength, although its basic characteristics and nylon 6 is similar, but due to the molecular weight higher than nylon 6 1.5 to 2 times, so the physical and mechanical properties also increased, high crystallinity, internal strain does not occur.
