本文着重阐述了利用本省廉价的有机物和无机物作添加剂改善水玻璃砂溃散性，在没有ＣＯ２ 供应的情况下，采用热烘法使水玻璃砂硬化，仍可取得湿态、干态强度，表面稳定性，抗吸潮性， 抗粘砂性，实际落砂性等较好的综合性能．在进行铸铁和铸钢生产应用试验中，获得满意的效果。 This article focuses on the use of inexpensive organic and inorganic substances in the province as additives to improve the collapsibility of water glass sands. In the absence of CO2 supply, the hot-baking method can harden the water glass sand and still obtain wet and dry strength. Stability, anti-absorbency, anti-adhesion, the actual sand-casting and other good comprehensive performance. In the application test of cast iron and cast steel production, satisfactory results were obtained.
