The higher the solid content of nano-silica water-based slurry, the better it is. Instead, it needs to be determined according to specific application needs and performance requirements.
Solid content refers to the proportion of solid components (i.e. nano-silica particles) in the slurry. A high-solid-content nano-silica water-based slurry means that it contains more effective ingredients at the same volume or weight, which can usually improve the performance of the product, such as enhancing the hardness, wear resistance, and aging resistance of the material. At the same time, a slurry with a high solid content may also reduce the use of solvents or water during the preparation process, which is beneficial to environmental protection and energy conservation and emission reduction.
However, too high a solid content may also bring some problems. First, a slurry with a high solid content may be more difficult to disperse during the dispersion process, requiring a more complex dispersion process and more dispersants, which will increase production costs. Secondly, too high a solid content may increase the viscosity of the slurry, making its fluidity worse, which is not conducive to construction and application. In addition, if the solid content is too high and the dispersion is uneven, it may also cause the nano-silica particles to form agglomerates in the material, affecting the overall performance of the material.
Therefore, when choosing nano-silica water-based slurry, the appropriate solid content should be determined according to the specific application scenario and performance requirements. For applications that require high hardness, high wear resistance and other properties, a slurry with a higher solid content can be selected; while for applications that require good fluidity and easy construction, a slurry with a moderate or slightly lower solid content may need to be selected. At the same time, attention should also be paid to performance indicators such as the dispersibility and stability of the slurry to ensure the quality and performance of the final product.
