On line disperser for settling fiber mica insulation material
Sedimentation fiber polymer materials have the characteristics of light weight, chemical corrosion resistance, easy processing and shaping, excellent electrical insulation performance, and excellent mechanical and fatigue resistance. However, the vast majority of polymer materials have extremely low thermal conductivity and are thermal insulators. If polymer materials are given a certain level of thermal conductivity, it will broaden their application fields. Thermal conductive and insulating polymer materials are of great significance for improving the accuracy and lifespan of electrical and microelectronic devices in insulation, heat dissipation, and thermal conductivity applications.
Surface treatment of POD precipitated fibers by disc grinding and ultrasound,After achieving a beating degree of 55-75 ° SR, it is added to the tank together with the above-mentioned content of mica and alumina, and then thoroughly stirred with a disperser for 8-20 minutes until the raw materials are evenly dispersed.Then, the evenly dispersed slurry is flowed into the stabilizing tank, and the grid valve of the stabilizing tank is adjusted to evenly distribute the slurry onto the forming mesh of the circular mesh paper machine. When the slurry runs along the forming net, the excess moisture is filtered out from the slurry using the pressure of the pressure roller. The paper embryo is driven by a blanket through a drying cylinder with a surface temperature of 75 ° C~90 ° C to further remove moisture, and then formed in one go through a winding machine. **Form high thermal conductivity insulation paper with a smooth surface, uniform uniformity, and outstanding characteristics.
The three-stage high shear dispersion machine is mainly used for the production of micro lotion and ultra-fine suspension lotion. Since three groups of dispersion heads (stator+rotor) in the working chamber work at the same time, after high shearing, the lotion drops are more delicate and the particle size distribution is narrower, so the stability of the generated mixed liquid is better. The three sets of dispersing heads are easy to replace and suitable for different process applications. The different models of machines in this series have the same line speed and shear rate, making it very easy to scale up production. It also meets the CIP/SIP cleaning standards and is suitable for food and pharmaceutical production.
High rotational speed and shear rate are important for obtaining ultrafine suspension lotion. According to some industry specific requirements, its shear rate can exceed 15000rpm, and the rotor speed can reach 44m/s. Within this speed range, turbulence caused by shear forces combined with specially developed motors can reduce the particle size range to the nanometer level. The shear force is stronger, and the particle size distribution of lotion is narrower.
