自硬水玻璃砂用有机酯固化剂的改性及在铸钢件生产中的应用

Modification of Organic Ester Curing Agent for Self-Hardening Sodium Silicate-Bonded Sand and Its Application in Production of Steel Castings

通过新型有机酯的改性与应用研究,将有机酯改性研究的理论与实践研究相结合,研究出满足四季生产需要的新型有机酯配砂工艺,制定了根据温度及季节变化的有机酯使用方法,从而成功研制出新型的水玻璃固化剂,达到在保证砂型内在质量的同时大幅度降低液料成本的目的,同时可以保证铸件质量,起到环境保护的作用,实现绿色造型的理念。

The study on the modification and application of a new type of organic ester for self-hardening water glass sand was carried out to meet the needs of four seasons molding production.The use method of the new type of organic ester was formulated according to the changes of temperature and seasons.This not only ensures the internal quality of the sand molds and castings,but reduces greatly the cost of fluid materials.At the same time,it plays a positive important role in environmental protection.
