减轻劳动强度

有益于环境保护

实现绿色铸造。

Abstract

There exist some shortcomings in traditional sodium silicate shell making process as a result of using NH4Cl and NH4Cl·H2O as hardener

such as heavy labor intensity

environmental pollution

and so on. A new type hardener was developed to overcome these problems. Application of the new hardener shows the improvement of operation circumstance

decreasing labor intensity and being beneficial for environmental protection as well as realization of clean casting.
