Metal chelating agent is a chemical substance with the ability to form stable complexes with metal ions. They typically contain ligands (also known as chelating agents) that bind to metal ions through coordination bonds to form complexes. The main functions of metal chelating agents are as follows: Stable metal ions: Metal chelating agents can react…

Scale and corrosion inhibitor is a chemical substance that prevents or reduces the formation of scale layers and alleviates corrosion by altering the behavior of soluble salts in water and the properties of metal surfaces. Scale inhibition principle: Coordination effect: Chemical substances in scale and corrosion inhibitors can react with dissolved salt ions in water….
Dispersants are a type of chemical substance commonly used in material processing and industrial applications to stabilize particles or dispersed phases and prevent their precipitation and agglomeration. There are various types and effects of dispersants, and the following are some common dispersants and their effects: Surfactants: Surfactants are a type of compound with hydrophilic and…
Polyacrylamide (PAM) is a synthetic polymer compound that belongs to the category of acrylamide polymers. It is prepared by polymerization of acrylamide monomers. Polyacrylamide has various structural and molecular weight derivatives, including linear polyacrylamide, partially hydrolyzed polyacrylamide, and polyacrylamide containing cationic groups. These different forms of polyacrylamide are widely used in many fields. The characteristics…
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…

Dispersant is a type of surfactant or polymer that can evenly disperse and stabilize solid particles in solution. The main principles of action of dispersants can be summarized in the following aspects: Dispersion effect: The dispersant forms a stable hydrophilic or hydrophilic oil layer by adsorbing on the surface of solid particles, making the particles…
Water reducing agent is a commonly used concrete admixture that can have the following effects in concrete: Reducing water cement ratio: Water reducing agents can change the fluidity of concrete, making it more prone to plastic deformation, thereby reducing the required amount of water. This can reduce the water cement ratio of concrete and improve…
