Surfactants can be classified based on their ionic properties, molecular structure, and application fields. The following are common classifications of surfactants: Non ionic surfactants: The molecules of non ionic surfactants are not charged and typically consist of compounds containing hydroxyl, ether, ester groups, etc. These surfactants exhibit good surface activity under neutral or slightly acidic…
TTA (Toluene-2,4,5-triamine) is an organic compound with various applications. The following are some common TTA application ranges: Photosensitive materials: TTA can be used as a component of photosensitive materials, such as photosensitive film, photosensitive resin, and photosensitive ink. It can absorb light energy and participate in chemical reactions, used in fields such as imaging, printing,…
Oilfield additives refer to various chemicals and materials used in the process of petroleum exploration and development, used to improve oil recovery and improve oil well production. Some oilfield additives may have certain hazards, but not all oilfield additives are classified as dangerous goods. In the application of oilfield additives, some hazardous chemicals may be…
Polyacrylic acid PAA is a commonly used polymer compound, widely used in medical, personal care products, and industrial fields. In general, polyacrylic acid has no direct harmful effects on the skin. Polyacrylic acid has good biocompatibility and tolerance, and is usually used to manufacture products that come into contact with the skin, such as dressings,…
Deoxidizer is a chemical used to remove dissolved oxygen from water. Its main working principle is to reduce the dissolved oxygen content in water by reacting chemically with oxygen dissolved in water, converting oxygen into other substances. The following are several common deoxidizers and their working principles: Sulfite (sodium sulfite, sodium bisulfite): Sulfite ions react…
ATMP (amino trimethylene phosphonic acid) is a commonly used corrosion and scale inhibitor. As an additive, ATMP plays the following roles in water treatment and industrial production: Corrosion inhibitor: ATMP can form a protective phosphate calcium oxide film covering the metal surface, preventing the reaction between the metal and dissolved oxygen, metal ions, etc. in…
Boiler water deoxidizer is a chemical used for boiler water treatment. Its main function is to remove oxygen from boiler water and prevent boiler corrosion and oxygen corrosion. The main components of common boiler water deoxidizers include the following: Nitrite: For example, sodium nitrite (NaNO2) or potassium nitrite (KNO2). Nitrite can react with oxygen to…
