摘要:
为改善电工级氧化镁普粉电性能的不足,使改性后电工级氧化镁粉更加适配电热管制造行业,通过加入白炭黑、电工级氧化镁用添加剂和硅油的方法对普粉进行改性,采用正交试验法设计25组配比组合进行试验。通过极差法分析单一指标(冷态绝缘耐压强度、泄漏电流和热态绝缘耐压强度)下的最优配比,并利用矩阵分析法实现多目标综合分析优化,得到优化后的组合配比,运用指标值预估法预测最终配比的电工级氧化镁改性粉的电性能。结果表明:以冷态和热态绝缘耐压强度为指标时,白炭黑掺量为主要影响因素;以泄漏电流为指标时,硅油掺量为主要影响因素,其次是电工级氧化镁用添加剂掺量。多目标优化选择的改性粉配比为白炭黑掺量0.25%(质量分数,下同),电工级氧化镁用添加剂掺量2%,硅油掺量0.25%。最终配比电工级氧化镁改性粉电性能预估值为冷态绝缘耐压强度3365 V,泄漏电流0.112 mA,热态绝缘耐压强度2399 V。
Abstract:
To improve its insufficient electrical property and make it more suitable for the electric heating tube manufacturing industry after modification, the plain electrical grade magnesium oxide powder was modified by adding silica,additive used in electrical grade magnesium oxide powder and silicone oil.Therefore, 25 groups of ratios were designed to carry out combined experiments. On the basis of the orthogonal experiment method. Analyze the optimal ratio under a single indicator (normal withstand voltage, leakage current and heating withstand voltage) with the range method. Also the matrix analysis method was used to analysis and optimize to obtain the optimal ratio,and the index value prediction method was used to predict the electrical property of the final ratio of modified electrical grade magnesium oxide powder. Finally, the results showed that the content of silica is the main influencing factor when the normal and heating withstand voltage is used as the indicator. However, when using leakage current as an indicator, the content of silicone oil is the main influencing factor, followed by the content of additive used in electrical grade magnesium oxide powder. In addition, the final parameters of the optimally selected backfill are as follows: 0.25wt% of silica,2wt% of additive used in electrical grade magnesium oxide powder,0.25wt% of silicone oil. Its estimated values of electrical properties of the final ratio of modified electrical grade magnesium oxide powder are normal withstand voltage of 3365 V, leakage current of 0.112 mA, heating withstand voltage of 2399 V.
