【摘要】：金属铝粉具有活性高、熔点低以及光泽度好等优良性能,广泛用于耐火材料、颜料、涂料及印刷油墨等行业,但铝粉易与水、氧气等反应致使其优良性能降低或丧失,而铝粉表面包覆改性对提高其在腐蚀性介质中的稳定性具有重要意义。综述了目前各工业领域用铝粉包覆改性的研究进展,并分析了各包覆改性方法对耐火浇注料用铝粉包覆改性的借鉴作用,进而对耐火浇注料用铝粉包覆改性的研究重点进行了展望。
[Abstract]:Aluminum powder is widely used in refractories, pigments, coatings, printing ink and other industries because of its high activity, low melting point and good glossiness. However, aluminum powder is easy to react with water and oxygen to reduce or lose its excellent properties. The surface coating modification of aluminum powder is of great significance to improve its stability in corrosive media. The research progress of aluminum powder coating modification in various industrial fields is reviewed. The reference function of each coating modification method to the aluminum powder coating modification of refractory castable was analyzed, and the research emphases of aluminum powder coating modification for refractory castable were prospected.
