由于流态砂这一新工艺的不断推广应用,水玻璃的需要量大幅度增加。为了解决制造水玻璃原材料(纯碱)供应的不足,沈阳市重工人民公社化工厂、红星公社化工二厂、沈阳机车车辆厂、沈阳重型机器厂等单位应用芒硝代替纯碱来生产水玻璃,初步解决了铸造生产中水玻璃供不应求的矛盾。现将他们用芒硝生产水玻璃的情况,介绍于下。 Due to the constant promotion and application of this new technology of fluidized sand, the demand for water glass has increased substantially. In order to solve the lack of supply of sodium silicate raw materials (soda ash), Shenyang Heavy Industries People’s Commune Chemical Plant, Red Star Chemical Plant No. 2, Shenyang Rolling Stock Plant, Shenyang Heavy Machinery Factory and other units of Glauber’s salt instead of soda ash to produce water glass, the initial solution Water glass in casting production contradicts demand. Now they use sodium sulfate production of water glass, introduced in the next.
