白水泥质量控制要点分析

白水泥作为常用的彩色硅酸盐水泥，其特点在于较高的白度，色泽明亮；但生产白水泥与通用硅酸盐水泥的差异在于白水泥烧成温度高，熟料液相量少、液相粘度高，并且其白度受着色元素的影响明显。本文介绍了生产白色硅酸盐水泥的质量控制要点，包括原材料的选择、过程质量控制要求、熟料的烧成和冷却以及白水泥粉磨的注意事项。

Analysis on key points of white cement quality control

As a commonly used colored Portland cement, white cement is characterized by high whiteness and bright color; but the difference between white cement and general-purpose Portland cement is that the white cement has a high sintering temperature and the amount of liquid phase in the clinker. Less, high liquid phase viscosity, and its whiteness is obviously affected by coloring elements. This article introduces the key points of quality control for the production of white Portland cement, including the selection of raw materials, process quality control requirements, the firing and cooling of clinker, and the precautions for white cement grinding.
