| 电工常用的绝缘材料根据其化学性质可分为无机绝缘材料、有机绝缘材料和混合绝缘材料。常用的无机绝缘材料包括云母、石棉、大理石、瓷器、玻璃、硫磺等。主要用于电动机和电器的绕组绝缘、开关底板和绝缘体等。有机绝缘材料包括虫胶、树脂、橡胶、棉纱、纸、大麻、人造丝等。它们主要用于制作绝缘漆、覆盖绕组线的绝缘层等。混合绝缘材料是由上述两种材料加工后制成的各种成型绝缘材料，用作电器的底座和外壳。 According to their chemical properties, electrical insulating materials can be divided into inorganic insulating materials, organic insulating materials and mixed insulating materials. Common inorganic insulating materials include mica, asbestos, marble, porcelain, glass, sulfur, etc. It is mainly used for winding insulation, switch base plate and insulator of motor and electric appliance. Organic insulating materials include shellac, resin, rubber, cotton yarn, paper, hemp, rayon, etc. They are mainly used for making insulating paint, covering the insulation layer of winding wires, etc. The mixed insulating material is a variety of molding insulating materials made of the above two materials after processing, which is used as the base and shell of electrical appliances. |
