Chromium-reducing cement and preparation method thereof
The invention provides chromium-reducing cement and a preparation method thereof, and solves the technical problems that in the prior art, ferrous sulfate and chromium-reducing cement are exposed in air, so that the chromium-reducing effect is influenced and the requirement on the use temperature is strict as the ferrous sulfate and the chromium-reducing cement are both gradually oxidized. The chromium-reducing cement comprises the following steps: by weight, 10-20 parts of alkylol amine, 5-15 parts of an inorganic salt, 2-20 parts of an organic acid and 45-83 parts of water. Due to the addition of a chromium-reducing grinding aid, the chromium-reducing grinding aid not only has the grinding aid effect of the grinding aid, but also has strong oxidation resistance, is suitable for long-termstorage, and can prevent the chromium-reducing effect from being influenced by oxidation during storage. A finished product is a uniform solution, so that pump blockage caused by precipitation accumulation can be avoided, the high-temperature-resistant performance is excellent, and the cement working condition temperature change can be well adapted. The production process is simple, operation andquality control are easy, and obvious technical advantages and wide market prospects are achieved.
本发明提供了一种降铬型水泥及其制备方法，解决了现有技术中的硫酸亚铁和降铬型水泥，由于暴露于空气中，硫酸亚铁和降铬型水泥均会逐渐被氧化，进而影响降铬效果，并且存在对使用温度要求严格的技术问题。其制备包括下述重量份的组分：醇胺10‑20份；无机盐5‑15份；有机酸2‑20份；水45‑83份。本发明中由于加入了降铬型助磨剂，其不仅具有助磨剂本身的助磨效果，而且抗氧化性强，适合长期存放，可以避免存放被氧化而影响到降铬效果；成品为均匀溶液，可以避免沉淀积聚易出现堵泵现象；且耐高温性能优异，能很好地适应水泥工况温度的变化；生产工艺简单，易于操作和进行质量控制，具有明显的技术优势和广阔的市场前景。
