1. High Viscosity Processing : Raw materials of silicone sealant usually have high viscosity, and sigma mixer is suitable for processing such high viscosity materials. Its powerful kneading action can fully mix high viscosity raw materials.
2. Uniform Mixing : The double-paddle design and strong kneading action of sigma mixer can effectively mix various raw materials (such as silicone polymers, fillers, plasticizers, cross-linking agents, etc.) evenly to form a uniform base material.
3. Preliminary Dispersion : During the kneading process, sigma mixer can also achieve a preliminary dispersion effect, preliminarily breaking up some larger particles, laying the foundation for subsequent fine dispersion.
Fine Dispersion and Degassing: Powerful Dispersing Mixer
1. Fine Dispersion : Although the materials initially mixed by sigma mixer are relatively uniform, there may still be some fine aggregates or iniadequately dispersed particles. Powerful dispersing mixer can further finely disperse these particles to ensure the uniformity and stability of the materials.
2. Degassing Function : Silicone sealant is prone to entraining air during kneading and mixing, resulting in bubbles in the finished product, affecting the sealing performance and appearance. Powerful dispersing mixer is usually equipped with a vacuum system, which can effectively remove air from the material during the dispersion process to ensure the density and quality of the final product.
3. Efficient Mixing : Powerful dispersing mixer has a high-speed rotating dispersing paddle that can provide strong shear force and mixing action, accelerate the mixing process of materiials, and improve production efficiency.
Q
Final Product Performance
• Stability and Consistency : Through the processing of theses two silicone sealant machines, the silicone sealant material can reach a highly uniform and stable state, ensuring that each batch of products has consistent quality and performance. • Material Property Optimization : The kneading and dispersion process can not only mix the raw materials, but also adjust the rheological properties of the materials, so that the final silicone sealant has good construction performance and curing characteristics during use.
