本文介绍采用酚醛夹布塑料制造的客车电气、播音连接器插销、插座外壳的性能特点,试验、试用情况。与原使用的铸铁材料相比,新材料不仅能减轻重量,节省金属材料;而且防锈、防腐性能好,有很高的绝缘性能,较好的机械性能;更由于工艺简单,可一次模压成型,故虽原材料成本高于铸铁材料,但总成本费仍低于铸铁材料。 This article describes the use of phenolic cloth cloth plastic manufacturing bus electrical, broadcast connector plug, socket shell performance characteristics, test, trial situation. Compared with the original cast iron material, the new material can not only reduce the weight and save the metal material, but also have the advantages of rust prevention and anticorrosive property, high insulation property and good mechanical property. Because of the simple process, the new material can be molded once Therefore, although the cost of raw materials is higher than that of cast iron, the total cost is still lower than that of cast iron.
