    (3)微硅粉在水中易形成 —Si-OH 基,具有较强的亲水性和活性,能增强耐火材料的凝聚,同时对高温性能有较大的改善,并可延长耐火制品的使用寿命。 
    微硅粉在耐火行业得到广泛应用。实际应用在以下几方面:

    SAN、WEIGUIFENDEQITAYONGTU:

    (1)、水泥工业:在水泥中添加微硅粉后,性能得到改善,质量、标号都大大提高。 
    (2)、橡胶工业:橡胶加一定量微硅粉后,其延伸缩、抗撕裂性和抗老化度有很大提高,这种橡胶还具有良好的介电性,吸水能力低。 
    (3)、作防结块剂:代替云母或硅藻土作防止肥料颗粒结块的原料。 
    (4)、作球团粘合剂:微硅粉比表面积大,吸附性强,在国外作球团矿的粘合剂取得显著效果。 
    (5)、水玻璃行业:可代替石英矿,生产出模数为 4 的水玻璃。 
    (6)、在油田作为固井使用:吉林油田、辽河油田、克拉玛依油田等,都大量使用微硅粉,并取得很好使用效果。 
    (7)、在绝缘材料、防水材料、油漆、涂料、印刷工业等都得到应用。 
FG美人捕鱼    我国目前拥有上千座硅铁及工业硅炉,年产微硅粉约 25 万吨,而现在环保设备收集的仅有 6 万吨左右,而大量的微硅粉被排放到大气中,直接污染了环境,同时也是对资源的浪费。因此,微硅粉作为一种不可再生的资源,对它的收集不但是一个环保效益,更是一个具有广阔经济价值的市场资源。
