无取向硅钢C6厚涂层性能的影响因素

本文介绍了无取向硅钢C6涂液的性能,研究了配水量、固化程度和涂层厚度等因素对无取向硅钢C6涂层性能的影响。结果表明,随着配水量的增加,完全固化所需的时间增加,涂液固体含量降低,涂层厚度减小;随着固化程度的提高,涂层硬度先增大然后趋于恒定,而柔韧性逐渐变差,在过固化后急剧恶化;涂层厚度对涂层的表面外观、附着性和绝缘层间电阻均有显著影响。

Research on Factors Influencing Performance of C6 Thick Coating of Non-oriented Silicon Steel Sheets

Based on the introduction about the performance of C6 varnish for non-oriented silicon steel sheets, effects of water amount, curing degree and coating thickness are discussed. Results show that with the increase of water amount, the time required to cure completely extends, and both the solid content of C6 varnish and the coating thickness decrease. As the curing degree increases, the hardness of the coating increases first and then tends to be constant, however the flexibility degenerates, especially after the over-curing. Besides, the coating thickness significantly influences the appearance, the adhesiveness and the layer resistance.
