    用途:主要用于铸造型砂、石棉保温材料(Material)中作为粘结剂;放射性废物吸收剂;农药中作载体或稀释剂、杀虫剂;钻井(Well drilling)泥浆冲洗液。

    1.提高湿压强度、热湿拉强度及破碎指数。

    2. 降低型砂水分,减少因水分过高而产生地铸件缺陷。

    3. 提高湿型砂地透气性,发气量低,防止铸件产生气孔。

    4. 有较好地韧性、塑性和砂粒表面地润湿性,使铸性表面致密、光滑,整体铸型强度均匀,起模性能(performance)好。

    5.增加造型砂地流动性,可缩短混砂时间,提高设备利用率。

    6.溃散性好,易于清砂,抛丸时间短,提高抛丸效率。

    7.提高湿型浇注初期地干强度和热湿拉强度,减少冲砂、夹砂、砂眼、气孔等铸件缺陷,提高铸件表面光洁度,提高成品率,有较好地直接经济效益和综合经济效益。
