【摘要】 这项工作的目的在于探讨分析纯和工业品硫化钠在不同条件下的氧化规律。实验结果说明潮解与碳酸化对产品的质量影响相当大,而氮气却有一定的防氧化作用。因此,硫化钠产品的包装对产品的质量有重大影响,若使产品熔化充氮后,又在氮气气氛中密闭保存是有益的。更多还原

【Abstract】 This experiment was done in order to explore the oxidized law of sodium sulfide in different atmospheres.It has shown that there is an important effect on the product quality from dampen decomposition and carbonatization of the product;on the other hand, nitrogen has an ability to protect the product from oxidation.Therefore, the package of sodium sulfide product has an major effect on its quality.It is beneficial that the product is stored in nitrogen after melting and nitrogenating.更多还原
