有机酯水玻璃自硬砂技术改造实践

The Practice of Organic Ester Sodium Silicate Self-Hardening-Sand Technical Transformation

本文介绍了有机酯水玻璃自硬砂技术改造的车间设计要点。成功开发出一种独具特色的非再生旧砂回收利用技术 ,该技术克服了水玻璃砂再生难的“瓶颈”制约 ,使生产成本大幅下降。通过对技术改造后的效果效益对比分析 ,证明了有机酯水玻璃自硬砂比原水玻璃七○砂具有无可比拟的优势 。

In this paper,the main design points of organic ester sodium silicate self hardening sand casting shop technical transfomation are introduced,anunusual technology of using no reclamed sand is successfully developedm. It overcomes the “vaes neck' restrict of sodium silicate sand reclamation, it maks the cost of productuon drop sharply, through analgsis comparison with benefit and resiut afrer technical transformation, it confirms organic estre sodium silicate self hardening sand has the great advantage than the old 70 sand,and it is one of the main technical transfomation direction of todays casting shop
