High-strength suspension insulator glaze-coated sand and preparation method thereof
The invention discloses high-strength suspension insulator glaze-coated sand and a preparation method thereof, and belongs to the technical field of porcelain insulator preparation. The high-strength suspension insulator glaze-coated sand is formed by blending glaze water and porous ceramic sand grains. The preparation method of the porous alumina ceramic sand grains comprises the following steps of: uniformly mixing kaolin, SiO2 powder, Al2O3 powder, a suspension thickener, a pore-forming agent and water according to a certain ratio to obtain slurry, then pouring the slurry into a mold, and carrying out drying, sintering, crushing and sieving to obtain sand grains with required grain sizes. The sand grains are light and hard, good in abrasion resistance and dense in surface air holes, and the bonding area between the sand grains and the glaze water is increased. The glaze-coated sand is applied to a surface glaze layer of a cementing part of a glazed porcelain rod body, and the sand grains protrude out of the glaze layer, so that the sand grains are not easy to fall off from the glaze layer after sintering, and the friction force of the cementing part of the porcelain rod body is enhanced. The raw materials and process for preparing the porous alumina ceramic sand grains are simple, reasonable in design and easy to implement, and the glaze-coated sand has good industrial application value.
本发明公开了一种高强度悬式绝缘子裹釉沙及其制备方法，属于瓷绝缘子制备技术领域。本发明的高强度悬式绝缘子裹釉沙是由釉水和多孔陶瓷沙粒调和而成，多孔氧化铝陶瓷沙粒的制备方法为：将一定比例的高岭土、SiO2粉、Al2O3粉、悬浮增稠剂、造孔剂和水混匀后制得料浆，然后浇模、干燥、烧结、粉碎和过筛，得到所需粒径的沙粒，其质轻坚硬，耐磨性好，表面气孔密集，增大了与釉水之间的粘结面积。将裹釉沙涂覆在已施釉完毕的瓷杆体胶装部位的表面釉层中并使沙粒突出釉层，烧结后，沙粒不易从釉层脱落，增强瓷杆体胶装部位的摩擦力。本发明制备多孔氧化铝陶瓷沙粒的原料和工艺较为简单，设计合理，易于实施，具有良好的工业应用价值。
