In today's rapidly evolving era, the demand for electricity is steadily on the rise. Electric porcelain insulators, which are essential for support and insulation, are experiencing increased demand and market growth. As a result, improving the performance of electric porcelain glazes has become a key focus for the industry. This article investigates how slurry parameters, such as water-to-material ratios, material compositions, and pH levels, influence the properties of electric porcelain glazes. The research suggests that incorporating materials like potassium feldspar reduces glaze viscosity, average particle size, Zeta potential, and Vickers hardness. An increase in water content lowers glaze viscosity while maintaining relatively stable average particle size and Zeta potential, with Vickers hardness initially increasing before it decreases. As pH values drop from 9.0 to 5.0, glaze viscosity initially decreases and then increases, average particle size follows a similar trend, Zeta potential rises, and Vickers hardness initially increases before it falls. Through optimization, using the formula: 16% wollastonite, 22% potassium feldspar, 20% quartz, 10% talc, and 32% kaolin, with a water-to-material ratio of 1:1, and adjusting the pH to 8.0, a high-performance electric porcelain glaze can be achieved. Its performance parameters include: a relative viscosity of 49, an average particle size of approximately 1.28 μm, a Zeta potential of 26.76eV, and a Vickers hardness of 247HV.
