Chelating agents are a type of chemical widely used in different fields, with great applications and value. Chelating agents can form stable complexes with metal ions, thereby possessing functions such as dissolution, stability, catalysis, or separation. Although chelating agents require careful handling during use, they are not generally considered hazardous chemicals. Here are some relevant…
Reverse osmosis scale inhibitor is a chemical that can effectively prevent and remove scale on the surface of reverse osmosis membranes, usually composed of multiple chemical substances. The following is a common method for preparing reverse osmosis scale inhibitors: Ingredients preparation: Mix sodium sulfite, disodium hydrogen phosphate, ethylenediaminetetraacetic acid (EDTA), hydrogen peroxide, and other components…

Deoxidizers typically refer to a type of chemical that can remove oxygen from liquids by reacting with oxygen to form oxides or carbon dioxide that are not easily soluble in water. And not all deoxidizers are reducing agents, some deoxidizers are non reducing agents. Deoxidizers can be roughly divided into the following two categories: Reducing…
Scale and corrosion inhibitors in water treatment chemicals are a type of chemical used to prevent scale and corrosion in water systems. Their main functions include: Scale inhibition effect: Scale inhibitors can react chemically with scale forming substances in the water system, changing their crystallization mode or forming water-soluble complexes, thereby preventing the formation and…

There is no unified standard for the allowable residence time of scale and corrosion inhibitors in the collection tank, which depends on multiple factors, including but not limited to the following: Water quality characteristics: Different water qualities have different rates of scale formation and corrosion. If the water quality in the collection tank is particularly…
Aluminum phosphide corrosion inhibitor is a commonly used corrosion inhibitor, mainly composed of aluminum phosphide and other auxiliary components. Aluminum phosphide has good corrosion inhibition performance in water, forming a protective phosphate film that covers the metal surface, thereby slowing down the corrosion rate of the metal. The working principle of aluminum phosphide corrosion inhibitor…
The main components of oxidative bactericidal agents include chlorine and peroxides. The following are common components of oxidizing bactericidal and algicidal agents: Hypochloric acid (HClO): Hypochloric acid is a highly oxidizing substance that can quickly kill bacteria, viruses, and algae. It can release free chloride ions (Cl -) in water and has a broad-spectrum bactericidal…

Cement based water reducing agent is a commonly used additive for concrete and cement products, which can reduce the amount of cement used in concrete while maintaining its strength and workability. The main components of common cement base water reducing agents include the following categories: Retarder: retarder can delay the setting time of cement slurry,…
The corrosion inhibitor HEDP (hydroxyethyl diphosphonic acid) is recognized as a hazardous chemical. Here are some safety information about HEDP: Irritation: HEDP has a certain degree of irritation and may cause irritation to the skin, eyes, and respiratory system. During use, direct contact with HEDP should be avoided and sufficient ventilation should be ensured. Toxicity:…
