The weather in Guangdong is cloudy and sunny. Last week the temperature dropped so much that you needed to wear a down jacket. This week the temperature has risen, but at the same time it has also ushered in the return of continuous humid weather. The return of the continuous humid weather is a special climate phenomenon, known for its high humidity and heavy rain. The air is humid and sticky, which makes people feel uncomfortable, and condensation on the ground turns into water.
People feel uncomfortable, not to mention electronic devices that need to be moisture-proof. The return of the continuous humid weather is undoubtedly a test for electronic devices.
The operation of electronic equipment depends on electronic components. Some electronic components cannot be affected by moisture and have poor moisture resistance, while others have good moisture resistance.Among them, film capacitors have unexpectedly good moisture resistance and have certain advantages when working in the continuous humid weather.
Film capacitors are capacitors that use metal foil or metalized film as electrodes and film dielectrics as dielectrics. They are small, light, and resistant to high temperatures and humidity, and are widely used in electronic devices. In terms of moisture resistance, film capacitors have certain advantages over other types of capacitors.
The good moisture resistance of film capacitors is due to the encapsulation coating material: epoxy resin.
Epoxy resin is a polymer formed by the polymerization of special chemical substances and is a type of thermosetting resin. It has a three-dimensional network cured structure and can be used in conjunction with a variety of curing agents.
Epoxy resin has many excellent properties, such as strong adhesion, heat resistance, chemical resistance, excellent mechanical properties and electrical properties. It also has excellent anti-corrosion, waterproof, anti-leakage and strong adhesion. It can be used in coatings for various products to play a role in corrosion resistance, waterproofness and anti-leakage.
The epoxy resin coating packaging material of the film capacitor is used to protect the inside of the film capacitor, prevent moisture intrusion, effectively isolate external moisture, ensure that the inside of the film capacitor is not affected by the humid environment, and play an important role in moisture-proof and corrosion-resistant.
Therefore, film capacitors can work normally in weather conditions such as the return of the continuous humid weather and provide energy for electronic devices. However, it should also be noted that electronic devices need to be placed in a place with suitable temperature and good ventilation to ensure normal operation.
