FXDJ Double Planetary Mixer: Assisting in the Production of Organic Silicone Adhesive
May 15, 2026
Organic silicone adhesive, with its high bond energy of silicon oxygen bonds, has excellent thermal stability, cold resistance, aging resistance, and electrical insulation properties. It is widely used in aerospace, electronics, construction, and other fields, mainly as a bonding sealant. The production of the FXDJ Double planetary mixer requires extremely high requirements for mixing uniformity, degassing effect, and temperature control accuracy. With advanced design and multifunctional configuration, it has become advantageous equipment for the production of organic silicone adhesive.
The FXDJ Double planetary mixer adopts a structure in which the planetary carrier drives the mixer to rotate synchronously with the scraper. The scraper runs closely against the inner wall of the material barrel, which can completely scrape off the material adhered to the barrel wall and avoid uneven mixing caused by retained material. For the common solid-liquid and liquid-liquid phases in the production of organic silicone adhesives, this equipment can quickly achieve uniform mixing of materials through strong shear and dispersion effects, especially suitable for the mixing of high molecular weight silicone rubber and reinforcing fillers, ensuring the adhesive strength and stability of the adhesive.
Organic silicone adhesive is sensitive to bubbles, which can reduce its sealing and weather resistance. The FXDJ Double planetary mixer can work in a vacuum environment, continuously removing moisture, low molecular weight volatiles, and entrained air from the material through the vacuum system, effectively avoiding the generation of bubbles. For example, in the preparation of silicone rubber, the raw rubber polymerized with octamethylcyclotetrasiloxane (D ₄) needs to have residual monomers removed. The vacuum degassing function of this equipment can significantly improve the density of the rubber material, meeting the demand for high-reliability sealants in fields such as aerospace and electronics.
The organic silicon polymerization reaction is temperature sensitive and requires precise control of the reaction temperature. FXDJ Double planetary mixer supports oil and water circulation or steam heating/cooling. The temperature is displayed and adjusted in real-time through a temperature controller to ensure that the reaction proceeds within the optimal range and avoid molecular chain degradation caused by local overheating. In addition, the equipment adopts a dual-column hydraulic lifting system, which ensures smooth and fast lifting of the cover and mixer. The mixing time can be flexibly adjusted through the control panel to meet the process requirements of different viscosity materials, making the operation simple and efficient.
The FXDJ Double planetary mixer is not only suitable for mixing silicone rubber adhesives, but also for processes such as silicone resin condensation reactions and silicone oil blending. Its efficient mixing, shearing, and dispersing capabilities can handle a full range of materials in organic silicon production, from low viscosity liquids to high viscosity elastomers, meeting the diverse needs of industries such as chemical and pharmaceutical for organic silicon products.
