Heavy metal chelators are a type of chemical substance that can react with heavy metal ions to form stable chelates. The composition can vary depending on specific products and applications, and the following are some common heavy metal chelating agent components: Secondary amines: Secondary amine compounds, such as ethylenediamine and pentanediamine, are often used as…
Water reducing agent is a commonly used concrete admixture that has the function of regulating the fluidity of concrete and reducing the water cement ratio (water cement ratio). The following are the main functions of water reducing agents: Improving fluidity: Water reducing agents can significantly improve the fluidity and pumpability of concrete. By reducing the…
Acid reverse osmosis membrane scale inhibitor is a chemical additive used in reverse osmosis systems, mainly used to prevent and reduce scale accumulation and pollution on the surface of reverse osmosis membranes, in order to maintain the efficient operation of reverse osmosis systems. Its main functions include the following aspects: Preventing carbonate scale: In reverse…
Metal ion chelating agents are a class of chemical substances that can form stable complexes with metal ions. They combine with metal ions through coordination bonds to form stable complexes and alter the chemical properties of metal ions. The following are several common metal ion chelating agents: EDTA (ethylene diamine tetraacetic acid): EDTA is a…
