High-strength ultrahigh-voltage hollow porcelain insulator and preparation method thereof
The invention discloses a high-strength ultrahigh-voltage hollow porcelain insulator and a preparation method thereof. The high-strength ultrahigh-voltage hollow porcelain insulator is prepared from bauxite, silicon dioxide, clay, feldspar, kaolin, magnesium oxide, sodium oxide, mullite, beryllium oxide powder and silicon powder. The preparation method comprises the following steps: step 1, selecting raw materials; step 2, ball-milling and sieving the raw materials; step 3, preparing mud and molding; step 4, glazing and firing; step 5, checking and screening; and step 6, assembling and inspecting. According to the high-strength ultrahigh-voltage hollow porcelain insulator and the preparation method thereof, bauxite, silicon dioxide, clay, feldspar, kaolin, magnesium oxide, sodium oxide, mullite, beryllium oxide powder and silicon powder are used as raw materials, a finished product is obtained through grinding, mud making, forming, glazing, firing and assembling, in the firing process,a formed green body is subjected to primary nitriding in nitrogen at the high temperature of 1200 DEG C, silicon powder and nitrogen react to generate silicon nitride, the strength of the product isimproved, the product quality is improved, and meanwhile the production cost is reduced.
本发明公开了一种高强度超高压空心瓷绝缘子及其制备方法，配方包括：铝矾土、二氧化硅、粘土、长石、高岭土、氧化镁、氧化钠、莫来石、氧化铍粉末和硅粉；制备方法，包括以下步骤，步骤一，原料选取；步骤二，球磨过筛；步骤三，制泥成型；步骤四，施釉烧制；步骤五，检查筛选；步骤六，组装检验；该高强度超高压空心瓷绝缘子及其制备方法，采用铝矾土、二氧化硅、粘土、长石、高岭土、氧化镁、氧化钠、莫来石、氧化铍粉末和硅粉作为原料，经由磨粉、制泥、成型、施釉、烧制、组装成成品，其中烧制过程中将成型坯体在氮气中及1200℃的高温下进行初步氮化，使得硅粉与氮气反应生成氮化硅，使其强度提高，提高了产品质量，同时降低了生产成本。
