1. Particle concentration: When the concentration of silica particles in silica sol increases, the interaction force between particles will increase, resulting in an increase in the flow resistance of the fluid, thereby increasing the viscosity and affecting adhesion and fluidity.
2. Temperature: As the temperature increases, the viscosity of the fluid decreases and the fluidity increases. Therefore, temperature is also an important factor affecting the adhesion and fluidity of silica sol.
3. pH value: The surface of silica sol particles carries a certain charge. Changes in pH value will affect the electrical properties of the particles, thereby changing the mutual repulsion or attraction between the particles, and thus affecting adhesion and fluidity.
4. Additives: The use of additives such as thickeners, dispersants and leveling agents will also significantly affect the adhesion and fluidity of silica sol. These additives affect the performance of silica sol by changing its flow behavior.
