Tips to prevent the 3240 epoxy sheet from aging

3240 epoxy sheet is an insulating material that mainly composed of electrical fiber glass cloth impregnated with epoxy resin and processed through drying and hot pressing. Its aging is an irreversible change process, but it can be delayed by a series of measures.

Tips to prevent the 3240 epoxy sheet from aging

‌Avoid strong sunlight: light aging is one of the main reasons for the aging of 3240 epoxy sheet. Sunlight radiation will make the board lose luster, fade, peeling and so on. Therefore, the sheet should be avoided from direct sunlight and dried in the sun or air even when moisture-proof ‌.
‌Control the use temperature: The use temperature of the 3240 epoxy sheet should be controlled at about 155 degrees to avoid exceeding the maximum use temperature. For every 8°C increase in ambient temperature, the life of the sheet will be halved. Therefore, try to avoid high temperature environment ‌.
‌Avoid high voltage: Although the voltage resistance of 3240 epoxy sheet is high, it is still necessary to avoid too high voltage in actual use to prevent the damage of partial discharge to the material‌.
‌Reduce mechanical vibration: The vibration and noise generated by mechanical equipment will cause serious harm to the insulation material, so the impact of mechanical vibration on the epoxy sheet ‌ should be minimized.

‌Corrosion prevention: Chemical corrosion ions in the air and chemical substances in chemical factories will cause corrosion to the epoxy sheet. We should take relevant protective measures to reduce corrosion ‌.

‌Keep a dry and cool environment: Epoxy sheet should be stored in a dry and cool environment, avoid direct sunlight and extreme temperature changes, in order to maintain its physical properties and appearance ‌.
‌Regular cleaning: Wipe the surface of the epoxy sheet with a mild cleaner and a soft cloth to remove dust and stains, avoid hard or rough materials that may scratch the surface ‌.
‌Repair surface scratches: For scratches or damage on the surface of the epoxy sheet, special epoxy resin repair agent should be used in time to repair, which prevents the expansion of damage and affect the performance of the material ‌.

Why prevent 3240 epoxy sheets from aging?

Maintain electrical performance: 3240 epoxy sheet, as an important insulating material, plays a key role in electrical equipment. The stability of its electrical performance is directly related to the safe operation of the equipment. Aging degrades the insulation performance of epoxy sheets, which may lead to electrical faults, equipment damage, or personal injury. Therefore, preventing aging is an important measure to ensure the normal operation of electrical equipment and the safety of personnel.
Maintain mechanical strength: Epoxy sheet has good mechanical strength and can withstand a certain amount of pressure and load. However, as the aging process progresses, its mechanical strength will gradually decrease, which may cause the sheet to deform, crack or break. This will not only affect the appearance and stability of the device, but may also affect the overall performance and service life of the device. Therefore, preventing aging is crucial to maintaining the mechanical strength of the epoxy sheet.

Improve economic benefits: Preventing 3240 epoxy sheet aging can also improve economic benefits. On the one hand, by extending the service life and reducing maintenance costs, equipment operating costs can be directly reduced. On the other hand, due to the wide application of epoxy sheets in electrical equipment, the stability and reliability of its performance have an important impact on the overall performance and operating efficiency of the equipment. Therefore, the prevention of aging can improve the overall performance and operational efficiency of the equipment, thereby improving economic benefits.

Ensure environmental safety: Hazardous substances and wastes that may be generated during the aging process pose potential threats to the environment. By taking scientific measures to prevent aging, the production and emission of these harmful substances can be reduced, so as to protect environmental safety.

It is extremely important to prevent the aging of 3240 epoxy sheets. In the use and maintenance process of epoxy sheets, great attention should be paid to preventing aging work, and effective measures should be taken to delay its aging process.
