摘　　要：主要研究了固砂釉的不同厚度对于烧成质量的影响、不同烧成条件的性能表现、坯釉结合处的微观结构,以及产品强度表现。结果表明:不同的固砂釉,性能存在差异,是影响瓷件外观,产品强度的主要因素之一。不同的固砂釉,上釉厚度表现不同,改进的固砂釉厚度可以达到0.22 mm左右。不同的烧成条件,固砂釉的性能随之变化,改进固砂釉的波动性更小,适应能力更强。坯釉匹配性是否良好,是否能够提高材料整体的性能,很大程度上取决于坯釉中间层的发育情况。低等级产品,固砂釉作用区别很小,高等级产品,固砂釉作用区别明显。制造高质量的性能稳定的电瓷绝缘子,需要有性能优良的固砂釉作为基础。The effect of different thickness of the sand glaze on the quality of firing, the performance of the sand glaze with different firing conditions, the microstructure of the porcelain and the glaze, and the strength of the product were studied. The results show that the properties of different sand glaze are different, which is one of the main factors affecting the appearance and strength of insulators products. Using different sand glaze, glaze thickness performance is different, the improved sand glaze thickness can reach about 0.22 mm. With different firing conditions, the performance of the sand glaze changes accordingly. Improved sand glaze is less volatile and more adoptable. Whether the glaze matching is good or not, can improve the overall performance of the material. It depends greatly on the development of the middle layer of the porcelain and glaze. Low grade products, the role of sand glaze distinction is very small, high grade products, sand glaze role obvious difference. It is necessary to have excellent sand glaze as the basis for making high quality and stable electrical porcelain insulators.
