Chemical dispersing agents mainly play the following functions:
Disclosure: Chemical decentralizers can evenly disperse solid particles or liquid droplets to liquid medium. By changing the surface properties of the particles, such as surface charge, hydrophobicity, etc., they reduce the interactive force between particles and prevent the particles from re -converging. This decentralized effect keeps the solid particles or droplets in a smaller and uniform size range and is scattered in the liquid.
Stable effect: Chemical decentralizers can stabilize the system to prevent the decentralization from re -converging or precipitated. They form a layer of adsorption layer on the surface of the decentralized body, providing a charge -impaired effect or an anti -agent effect, thereby preventing the mutual attraction and aggregation between particles or droplets. This stability can extend the stability of the decentralized body and maintain a uniform dispersing state.
Streaming adjustment function: Chemical dispersing agents can regulate the fluidity of the decentralized system, such as viscosity and liquidity. They can increase the interaction between decentralized and liquid, change the arrangement methods and movement characteristics of the decentralized body, and affect the flow of the entire system. This regulatory effect is particularly important for coatings, inks, and other applications that require specific streaming performance.
Compatibility enhancement effect: Chemical dispersing agents can improve the compatibility between different components. In a complex system, the interaction of different components may lead to separation or unstable phase. Chemical dispersing agents are adsorbed on the interface, reducing the mutual rejection between different components, improving their compatibility, thereby improving the stability of the entire system.
You need to choose the appropriate chemical dispersant according to the specific application requirements, and follow the correct proportion and usage method during use. At the same time, for different systems and materials, experiments and optimizations may be required to obtain the best dispersion effects.
