High-temperature-resistant cement hexavalent chromium reducing agent
The invention discloses a high-temperature-resistant cement hexavalent chromium reducing agent, which is prepared from the following components in parts by weight: 2-4 parts of stannous sulfate, 20-25parts of ferrous sulfate, 3-5 parts of montmorillonite, 2-4 parts of bentonite, 3-5 parts of magnesium fluoride and 3-5 parts of humic acid. The reducing agent has stronger high temperature resistance, and hexavalent chromium in cement can be more effectively reduced, so that the using amount of the reducing agent is relatively less, the cost is lower, and the cement performance is good.
本发明公开了一种耐高温的水泥六价铬还原剂，按重量份计由如下组分组成：硫酸亚锡2~4份，硫酸亚铁20~25份，蒙脱土3~5份，膨润土2~4份，氟化镁3~5份，腐殖酸3~5份。该还原剂有更强的耐受高温能力，并且能够更有效地还原水泥中的六价铬，从而还原剂的使用量相对更少，成本更低，并且使水泥性能好。
