sodium gluconate

Boric acid ester, tri ethanolamine salt of substituted benzoic acid and sodium gluconate were used as anti rust additives in water based cutting fluid.

以硼酸酯、取代苯甲酸乙醇胺盐、葡萄糖酸钠三者为混合防锈剂应用于切削液中，其中硼酸酯和取代苯甲酸乙醇胺盐有明显的协同效应。

The content of boric acid ester, tri ethanolamine salt of substituted benzoic acid, sodium gluconate in cutting fluid was 10%, 6%, 1%, respectively.

实际配方中硼酸酯、取代苯甲酸乙醇胺盐、葡萄糖酸钠的含量分别为10%、6%和1%。

However, For the appropriate contents of sodium gluconate after the inflection point of resistivity curve, the slope of resistivity curves is gradually increasing with hydration.

随着水化的进行，适宜葡萄糖酸钠掺量的电阻率曲线达到拐点后，电阻率曲线的斜率逐渐增大。
