Raw Material Introduction

The cement chromium removal agent is a new type of cement additive designed to help cement companies meet the requirements of domestic and international regulations on chromium content, especially the national mandatory standard GB31893-2015. With the implementation of the hexavalent chromium limit standard, our company will rely on its strong research and development capabilities to provide better products and services for cement enterprises.

The cement chromium removal agent mainly acts in cement production to reduce hexavalent chromium in cement, thereby reducing the chromium ion content in cement. With the implementation of the regulations on the limit and determination method of water-soluble chromium in cement issued in 2016, the standards for water-soluble chromium content in cement have been strictly restricted, which has greatly increased the quality control requirements of major cement manufacturers and further improved the technical requirements for the treatment of water-soluble chromium in cement products.

The product mechanism of the chromium removal agent involves a combination of organic chromium compounds, dispersants, emulsifiers, nano catalysts, rare earths, and more than a dozen other materials after ultra-high pressure reaction, followed by rapid shearing, emulsification, and homogenization. The chromium removal agent can organically combine with water-soluble hexavalent chromium ions and has a reduction function, forming stable precipitates that will not overflow from the cement slurry, fundamentally solving the harm of hexavalent chromium to the body. It is packaged in ton bags, ensuring maximum storage stability and operational convenience.

Usage Method

The method of using the chromium removal agent is similar to traditional cement additives and can be directly added to the grinding system. Within the range of 5ppm-30ppm of hexavalent chromium content, the dosage shows a linear relationship with the reaction of hexavalent chromium, and it maintains very stable performance for different mills and clinkers. The dosage is low, generally 0.3%-1% of the cement content, mainly depending on the hexavalent chromium content in the cement, followed by the cement grinding treatment and storage conditions.
