Plate of vacuum impregnated sheet processing is a type of cover plate made using vacuum impregnation technology, which usually has excellent electrical, mechanical, and processing properties. Here is a detailed introduction about it:
materials and processes
Material: Plate of vacuum impregnated sheet processing is usually reinforced with fiber fabrics such as glass fiber cloth, glass yarn, glass felt, etc., with epoxy resin as the matrix resin, and additives such as acid anhydride, toughening agent, and accelerator added. The fiber content is generally 40% -70%, and this material combination gives the cover plate good insulation performance and mechanical strength.
Craftsmanship: The production process generally includes cutting, stacking, molding, preparation of vacuum impregnated resin, low-pressure vacuum impregnation, initial curing inside the mold, demolding, post curing, and finished product packaging. Firstly, the various components of the resin are added to a mixing and degassing kettle, and stirred and degassed at a certain temperature and vacuum degree to prepare vacuum impregnated resin. Then stack the cut fiber fabric blanks in the mold, preheat the mold, and inject the vacuum impregnated resin into the mold under low-pressure vacuum to fully infiltrate the fiber fabric. Finally, after initial curing, demolding, and post curing processes, the plate of vacuum impregnated sheet processing is obtained.
Performance Characteristics
Excellent electrical performance: Due to the use of vacuum impregnation technology, the air gap content of the cover plate is low, generally less than 0.5%, which makes it have good insulation performance, high voltage resistance, excellent partial discharge characteristics, and can work stably under high electric field strength.
High mechanical strength: The good combination of fiber fabric and resin endows the cover plate with high mechanical strength, making it resistant to mechanical impact, fatigue and other properties, able to withstand certain external forces, and not easily deformed or damaged.
Good processing performance: Vacuum impregnated plywood has good processing performance and can be processed into various shapes and sizes of cover plates through drilling, cutting, polishing and other processing methods to meet different usage needs.
Good heat resistance and moisture resistance: This cover plate has good heat resistance and can maintain stable performance under certain high temperature environments. It also has good moisture resistance and is not easily affected by humid environments, making it suitable for use in various environmental conditions.
Application field
In the field of electrical equipment, vacuum impregnated rubber sheet processing cover plates can be used in high-voltage switchgear, transformers, transformers and other electrical equipment as insulation partitions, cover plates and other components to insulate and protect internal components.
In the field of molds, such as plastic molds and injection molds, it can be used as an insulation board to avoid mechanical wear, reduce the preheating cycle time of mold equipment, and ensure uniform heat distribution in the mold cavity, thereby improving the performance of the mold.
