Quali prestazioni e come rileva l'agente antisedimentazione?
L'antisedimentante è una sostanza chimica, solitamente utilizzato nelle vernici, coloranti, adesivi e altri prodotti, che può prevenire i pigmenti, riempitivi, particles and other substances from settling, to maintain the uniformity and stability of the product. The anti-settling agent usually achieves the anti-settling effect by electrostatic interaction or adsorption with the surface of solid particles in the paint. The common antisettling agents are organic amines, polyacrylamide, polyvinyl alcohol and so on.

Metodo di rilevamento
Composizione chimica: Common detection methods include infrared spectroscopy, spettrometria di massa, nuclear magnetic resonance and so on. These methods can be used to determine the chemical composition and structure of the antisettling agent.
Distribuzione delle dimensioni delle particelle: The particle size of the anti-settling agent is important for its dispersion performance and anti-settling effect. Common particle size measurement methods include laser particle size analyzer, microscopio elettronico e così via.
Surface potential: The surface potential of an antisettling agent can affect its action with paint or pigment particles. Common test instruments include potentiometers, Zeta potentiometers, eccetera.
Adsorption performance: The adsorption performance of the anti-settling agent can affect its dispersion performance and anti-settling effect in the paint or adhesive. Common test methods include adsorption measurement, isothermal adsorption curve test and so on.
Electrostatic effect: Electrostatic effect is an important anti-settling agent mechanism. Common test instruments include electrostatic tester, surface potential tester and so on.

Dispersion performance: The dispersion performance of the antisettling agent can affect its uniformity and stability in the paint or adhesive. Common test methods include suspension state observation, viscosity test and so on.
Durability: The anti-sedimentation agent needs to maintain its performance and effect under the conditions of use. Common test methods include exposure test, humid heat cycle test and so on.
We reminds you that different types of anti-sedimentation agents may need to be tested for their specific properties, and the specific test methods and instruments may also vary according to the different types of anti-sedimentation agents.
