摘要
本文研究在满足水玻璃砂铸型(芯)工艺性能的前提下,降低其浇注后的残留强度,改善其溃散性的技术措施及其机理,介绍了Ⅰ型(Wg-SH-AMG)及Ⅱ型(Wg-AMGF)改性水玻璃砂的生产过程及技术性能。这两种产品在实验室及生产中均取得满意效果,与国内外同类产品比较,各方面的性能均较优良,且经济效益好,铸件质量高,本产品是一种值得推广的新型材料。
This paper researches the technical approaches and mechanism of lowering the residual strength and improving the collapsibilities of water-glasss sand.Two kinds of binders,Wg-SH-AMG and Wg-AMGF modified water-glass sand are introduced, which have been successfully used in laboratory and production in foundry work. Comparing with the other binders produced at home and abroad,the binders pos- sess better performanc in the areas of strength,post-casting breakdown,and storage properties,as well as economic efficiency.
