And SDDTC and zinc sulfate, sodium chromate corrosion inhibitors of the compound has good synergies, all of this research has important practical application of significance.
而且SDDTC与硫酸锌，铬酸钠之复配缓蚀剂具有很好的协同增效作用，这一切相关研究具有重要的实际应用意义。
The effects of the calcine size, leaching temperature, leaching time and solution-solid ration no the leaching rate of the sodium chromate in the chromium calcine are investigated.
结果表明，在试验的浸出条件下，铬焙砂粒度对铬浸出率的影响不显著，铬浸出率随浸出温度升高、液固比增大和浸出时间延长而增加。
