Description

Technical Field

[0002] An insulating composite material is a material composed of two or more components with different chemical and physical properties, combined in a specific form, proportion, and distribution. These components have distinct interfaces, allowing for structural design and composite structural design. Insulating composite materials not only retain the advantages of each component material but also, through the complementary and interrelated properties of each component, achieve comprehensive performance that cannot be achieved by a single component material. This material is non-conductive at the permissible voltage and has a very high resistivity. Insulating composite materials have a wide range of applications. For example, in motors, the insulating material surrounding the conductor isolates the turns from each other and from the grounded stator core to ensure safe operation of the motor.

Most existing drying devices do not have a stirring mechanism, which makes the drying of the middle part of the accumulated solid particles relatively slow. Therefore, the market urgently needs to develop a drying device for the preparation of insulating composite materials to help people solve the existing problems. Utility Model Content
