本文使用 NanoZs-90Zeta 电位计研究了不同种类的以及不同成分的二氧化钛的 Zeta 电位。测试了由具有不同等电点 pH 值的二氧化钛颜料制备的丙烯酸乳胶漆的分散性，覆盖性，耐候性和耐候性。主要性能指标（例如光泽度）用于指导丙烯酸乳胶漆的二氧化钛的生产。结果表明，硅铝涂层的量，pH 值和二氧化钛的电阻率对二氧化钛的 Zeta 电位有很大的影响。具有较高 SiO2 涂层的二氧化钛可以降低等电点 pH 值，并改善丙烯酸乳胶漆的分散性、耐候性以及隐藏动力。“,”This article uses NanoZs-90Zeta potentiometer to study the Zeta potential of different types and compositions of titanium dioxide. The dispersibility, coverage, weather resistance and weather resistance of acrylic latex paints prepared from titanium dioxide pigments with different isoelectric points and pH values were tested. The main performance indicators (such as gloss) are used to guide the production of titanium dioxide in acrylic latex paint. The results show that the amount of siliconu0002aluminum coating, the pH valueand the resistivity of titanium dioxide have a great influence on the zeta potential of titanium dioxide. Titanium dioxide with a higher SiO2 coating can lower the pH value of the isoelectric point and improve the dispersion, weather resistance and hidden power of acrylic latex paint.
