Function:
1.Diethylene glycolamine has good alkalinity and can react chemically with acidic gases, it is a kind of efficient acidic gas absorber.
2.Diethylene glycolamine can be used as solvent or co-solvent.
3. Diethylene glycol amine has the function of pH regulator.
4. Diethylene glycol amine can be used as chain extender in polyurethane synthesis.
5. Diethylene glycolamine can be used as a component of metal cutting fluid. It can provide lubrication and cooling functions to reduce friction and heat generation in the metal cutting process.
6. As a component of metal cleaners, diethylene glycolamine can remove impurities such as oil, dirt and rust from metal surfaces.
Application:
1. In the process of industrial gas treatment such as natural gas and refinery gas, it can absorb acid gases such as carbon dioxide (CO₂) and hydrogen sulfide (H₂S), reducing corrosion of pipelines and equipment, and also meeting the requirements of environmental protection.
2. Used in the production of coatings and paints, it can dissolve a variety of resins, pigments and other ingredients, so that the paint has good fluidity and coating performance.
3. In paint formulations, it can maintain the alkaline environment of the paint system, which helps to prevent certain components in the paint (e.g. emulsion polymers) from coalescing or deteriorating under acidic conditions.
4. It can be used in the preparation of polyurethane elastomers, as well as regulating the hardness and flexibility of polyurethane, making it suitable for different application scenarios, such as shoe soles and seals.
5. When metal processing, it forms a lubricating film between the tool and the workpiece to reduce the cutting force, while its alkalinity prevents the metal surface from rusting and prolongs the service life of the tool.
6. When cleaning steel products, diethylene glycol amine can effectively remove grease and rust on the surface.
