Chromium removal agents (chromium reducing agents) are widely used in cement production. Local companies still need to continuously improve production technology.

Chromium removal agent, also known as chromium reducing agent, chromium removal liquid, and chromium removal liquid, refers to a chromium-containing wastewater treatment agent. It appears as a gray-white powder and is easily deliquescent and soluble in water. The chromium removal agent has chelating groups such as -COOH (carboxyl), -NH2 (amino), -OH (hydroxyl), etc., which can react with chromium ions in chromium-containing wastewater to form a stable cross-linked network of insoluble matter and precipitate.

Chromium remover is a key material required for wastewater chromium removal process using chemical precipitation method. Compared with similar products, chromium remover has safe ingredients, high environmental protection, high cost performance, easy operation, excellent treatment effect, and stable chromium removal. It has high advantages and is widely used in cement, electroplating, electronics, metallurgy, film processing, chemistry and other fields.

Cement is the main application field of chromium remover. Affected by the production raw materials and equipment, the content of hexavalent chromium in cement is relatively high, and hexavalent chromium will spread to tap water treatment pools, residential houses and other places with the application of cement in construction, which will have a negative impact on human life safety. Therefore, cement production needs to strictly control the content of hexavalent chromium. The mandatory national standard gb31893-2015 issued by the country in 2015 clearly limits the content of hexavalent chromium in cement to no more than 10 mg/kg.

Chromium removal agents are a type of key additive that can effectively remove hexavalent chromium in cement. In recent years, as domestic cement production continues to increase, its demand has continued to increase, and the industry has broad prospects for development. At the same time, chromium remover is a key agent for the treatment of chromium-containing wastewater by-products of electroplating production, and its industry development is favored by the rapid development of the electronics industry.

The most commonly used chromium remover on the market today is ferrous sulfate chromium remover, which uses ferrous sulfate, polyglycerol, bentonite, organic complexes, dispersants, etc. as raw materials, and is produced through high-pressure reaction, shearing, emulsification, etc. The medicine has the advantage of high cost performance. However, ferrous sulfate also has shortcomings such as being easily oxidized by air and failing, and having poor stability, which has an important impact on the effectiveness of chromium removers. Therefore, in the future, relevant companies will need to continue to improve their process levels and increase product innovation to promote chromium remover products. The speed of update iteration is accelerating.

According to the“Research on Market Monitoring and Future Development Prospects of China’s Chromium Removing Agent (Chromium Reducing Agent) Industry from 2023 to 2027” released by the Industrial Research Center The report shows that the domestic chromium removal agent manufacturers mainly include Sichuan Reluo Environmental Protection Technology, Sichuan Fengge Technology, Guangzhou Xijie Environmental Protection Technology, Jiangxi Zhongjin Environmental Protection Technology, and Sichuan Sulik Environmental Protection Technology , Foshan Jianghe Chemical, Chongqing Delxin Industry and Trade, etc., there are many companies.

Industry analysts said that chromium remover is a type of chromium-containing wastewater treatment agent, which is widely used in cement, electroplating, electronics and other fields. wide. Among them, cement is the largest application field of chromium removal agents. In recent years, as domestic cement production standards have become increasingly strict and cement production has continued to rise, the demand for chromium removal agents has continued to increase, and the industry has shown good development prospects. There are a large number of chromium remover manufacturers in my country. In the future, local companies will need to accelerate the improvement of their technical level and promote the continuous acceleration of the update and iteration of chromium remover products.
