為改善電工級(jí)氧化鎂普粉電性能的不足，使改性后電工級(jí)氧化鎂粉更加適配電熱管制造行業(yè)，通過加入白炭黑、電工級(jí)氧化鎂用添加劑和硅油的方法對(duì)普粉進(jìn)行改性，采用正交試驗(yàn)法設(shè)計(jì)25組配比組合進(jìn)行試驗(yàn)。通過極差法分析單一指標(biāo)（冷態(tài)絕緣耐壓強(qiáng)度、泄漏電流和熱態(tài)絕緣耐壓強(qiáng)度）下的最優(yōu)配比，并利用矩陣分析法實(shí)現(xiàn)多目標(biāo)綜合分析優(yōu)化，得到優(yōu)化后的組合配比，運(yùn)用指標(biāo)值預(yù)估法預(yù)測(cè)最終配比的電工級(jí)氧化鎂改性粉的電性能。結(jié)果表明：以冷態(tài)和熱態(tài)絕緣耐壓強(qiáng)度為指標(biāo)時(shí)，白炭黑摻量為主要影響因素；以泄漏電流為指標(biāo)時(shí)，硅油摻量為主要影響因素，其次是電工級(jí)氧化鎂用添加劑摻量。多目標(biāo)優(yōu)化選擇的改性粉配比為白炭黑摻量0.25%(質(zhì)量分?jǐn)?shù)，下同)，電工級(jí)氧化鎂用添加劑摻量2%，硅油摻量0.25%。最終配比電工級(jí)氧化鎂改性粉電性能預(yù)估值為冷態(tài)絕緣耐壓強(qiáng)度3365 V，泄漏電流0.112 mA，熱態(tài)絕緣耐壓強(qiáng)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.
