In the scattered carbon black, the commonly used carbon black dispersing agent mainly includes the following:
Active surfactant: The anionic surfactant is one of the most commonly used carbon black dispersant. For example, sodium sulfate, sulfonate, sodium bayate, etc. These anion surface activated agents can be adsorbed on the surface of carbon black. Through the static effect, the carbon black particles interact with the carbon black particles, thereby achieving the dispersal stability of the carbon black.
Catalogenic surfactant: The cationic surfactant can also be used as a carbon black dispersant, but it is used less. For example, hexadecanel tritenium bromide. The cationic surfactant interacts with carbon black particles through static electricity and hydrophobic groups to achieve the dispersion and stability of charcoal black.
Non -ion surface active agent: Non -ion surfactants also have certain applications in carbon black dispersing. For example, duoline polyxidyl oxygenne ether, ethylene polyoxide ether, etc. These non -ionic surfactants interact with water molecules through their hydrophilic groups, and use the active oil group and charcoal black particles to achieve causing black dispersal stability.
Polymer dispersant: Polymer dispersant is also commonly used in charcoal black dispersing, such as polyacrylamide, polyethylene pyrodidone, etc. These polymer dispersers form a physical adsorption or chemical bond with the long chain structure and functional group to achieve the dispersing stability of the carbon black.
According to the specific application requirements and the nature of carbon black, you need to choose the appropriate dispersant. At the same time, you must refer to related literature and technical materials to ensure the correct selection and use of the dispersant, and achieve the expected carbon black decentralization effect.
