Chelating agents are a class of compounds with specific chemical structures that can form stable complexes with metal ions. Chelating agents form coordination bonds between their specific functional groups and metal ions, achieving specific binding with metals. The principle of chelating agents can be explained through the following aspects: Coordination effect: Functional groups (usually atoms…
Reverse osmosis scale inhibitor is a chemical agent used in reverse osmosis (RO) systems to prevent and reduce scale accumulation and blockage on the surface of RO membranes. The principle can be explained as follows: Dispersion effect: The dispersant PAA in reverse osmosis scale inhibitors can interact with inorganic salts, organic matter, and particulate matter…
Reverse osmosis scale inhibitors are chemicals used to remove and prevent scale formation on the surface of reverse osmosis membranes. The choice of dosing concentration depends on multiple factors, including water quality characteristics, membrane type, operating conditions, etc. Generally speaking, the following are some suggestions for using reverse osmosis scale inhibitors: Initial dosing concentration: Determine…

Deoxidizer is a chemical agent used to remove oxygen from water and prevent corrosion. Generally speaking, deoxidizers are usually composed of the following main components: Oxalic acid or sulfite: These substances can react with oxygen as reducing agents to remove dissolved oxygen from water. Oxalic acid and sulfite are widely used because of their high…
Multipurpose acid pickling corrosion inhibitor is a chemical that contains acidic components and therefore has a certain degree of danger. Please note the following points: Corrosiveness: Multi use acid pickling corrosion inhibitors usually contain acidic components such as hydrochloric acid, nitric acid, etc. These substances have corrosiveness. Chemical burns may occur when in contact with…

Mud stripping agent usually refers to a chemical agent used to remove mud or adhesive substances from surfaces such as walls and floors. In general, clay stripping agents belong to non oxidizing stripping agents. Non oxidizing stripping agents mainly dissolve, soften, or decompose the molecular structure of adherent substances, causing them to lose their adhesion,…
Polyacrylate PAA lotion matting powder is a kind of white inorganic pigment, which is usually used in printing, coating, plastic products and other industries. It is composed of polymer particles and inorganic pigments such as titanium dioxide, and has good covering, dispersion, and precipitation resistance. The use of polyacrylate lotion matting powder can make the…
The dosage of reverse osmosis scale inhibitor depends on multiple factors, including water quality, membrane type, and operating conditions. Generally speaking, the dosage should be adjusted according to the specific situation to ensure the best scale inhibition effect and membrane performance. Usually, the dosage can be determined according to the following steps: 1….
