粉煤灰空心微珠是用物理方法从粉煤灰中分选出来的一种以硅、铝氧化物空心玻璃球为主要组成物的粉状材料,由于它具有质轻、粒细、表面光滑、强度高、耐高温、耐磨以及绝缘阻燃等一系列优异性能,因而近年来在建材、建工、冶金、塑料、轻工等领域的工业生产中获得了较为广泛的应用。 Fly ash hollow microspheres are a kind of powder material with silicon, aluminum oxide hollow glass spheres as the main composition, which is separated from fly ash by physical methods, because of its light weight, fine grain, and smooth surface. High-strength, high-temperature resistance, wear-resistance, and insulation and flame-retardant properties have led to a wide range of applications in building materials, construction, metallurgy, plastics, and light industry.
