PE—01型水玻璃砂溃散剂的研制与应用

Developmentand Application of the PE-01 Sodium Silicate Sand Collapsibility

试验研究了ＰＥ—０１溃散剂的加入量与芯砂性能的关系，并与其它同类产品进行了对比。

The relations between the adding amount of the PE-of collapsibility and the properties of core sandare presented,and the collapsibility is compared with the same kinds of products.
