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…

Corrosion inhibitor DTPMPA is a chemical used to prevent metal corrosion and is widely used in industrial production and metal processing. Here are some common quality standards and guidelines for corrosion inhibitors: The International Organization for Standardization (ISO) standard: ISO 7120:2017 “Metal Corrosion Inhibitors and Inhibitors – Determination Methods” provides guidance on the evaluation of…
The commonly used chemicals in tap water treatment include the following: Flocculant: Flocculant is used to aggregate small particles suspended in water into larger flocs for subsequent filtration and sedimentation. Common flocculants include polyaluminum chloride (PAC), polyferric sulfate (PSF), and polyacrylamide (PAM). Disinfectant: Disinfectants are used to inactivate bacteria, viruses, and other microorganisms in water,…
Polyacrylic acid sodium PAAS is a negatively charged polymer compound commonly used as a flocculant, dispersant, and corrosion inhibitor. The following are the main functions and uses of sodium polyacrylate: Flocculant: Sodium polyacrylate can adsorb suspended particles in water and form larger flocs, thereby helping the suspended solids settle quickly or filter through filters. It…
