Silicon emulsions are widely used in a variety of industries such as cosmetics, medicine, and paint manufacture. Due to their inert nature, silicon-based emulsions are often used as emulsifiers. To ensure the stability of the droplets and for the efficient development of the product, a high-pressure homogenizer must be used in the production of silicon emulsions. In this article, we will discuss the advantages of using a high-pressure homogenizer for silicon emulsion production.
What Is Silicon-Based Emulsions?
Silicon-based emulsions are silicone oils dispersed in an aqueous system. These emulsions are ideal for surface treatment, and they are easy to apply and prepare. The high viscosity of some silicone oils can be reduced through emulsification, which is why they are so widely used in the production of a variety of products.
Uses of High-Pressure Homogenizer for Silicon Emulsion Production
High-pressure homogenizers are essential to produce silicon emulsions. Many everyday products contain silicone liquids, such as adhesives, lubricants, pharmaceuticals, cleaning products, insulation materials, and electrical insulation. In the manufacturing of silicone grease lubricants or coatings, the silicone liquid must be homogenized optimally when mixed with other materials or water. Silicone mold separators also require homogenization to emulsify the silicone and disperse it homogeneously through the water phase.
Advantages Of High-Pressure Homogenization
Through high-pressure homogenization, the particle size of the product is significantly reduced. When operating at pressures higher than 500 bar, the particle sizes reach 1 micron and below. High-pressure homogenization also helps to stabilize the emulsion of silicone oil, as it can be improved by changing the surface properties through a combination of techniques.
Using a High-Pressure Homogenizer
Silicone emulsions can be prepared using a homogenizer or colloid mill, depending on the viscosity of the silicone oil, the amount of oil in the formulation, and the droplet size desired. The homogenizer is most efficient with low-viscosity products, and it should not be used if the viscosity exceeds 1000cP. On the other hand, if the percentage of oil exceeds 50%, then the colloid mill should be used.
Conclusion
High-pressure homogenization is essential to produce silicon emulsions. It helps to reduce particle size and homogenize the product, resulting in improved product stability. A high-pressure homogenizer or colloid mill can be used to prepare the emulsion, depending on the product’s characteristics. With the use of a high-pressure homogenizer, efficient and effective production of silicon emulsions can be achieved.
