Core Pain Points of Charger Sealing in the Electronics Industry
As electronic consumer products, chargers are constantly exposed to temperature changes, humidity, and even dust in daily use. If the sealing parts of their internal components are not properly handled, issues such as water ingress and short circuits, adhesive layer cracking at high temperatures, and adhesive layer aging and failure after long-term use may occur. These problems not only affect the product lifespan but may also pose safety hazards. Therefore, suitable sealing adhesives are key to ensuring charger reliability.
Airosen's Adhesive Selection Approach
Combined with the sealing needs of chargers in the electronics industry, Airosen recommends selecting flange sealants, thread locking agents, and matching cleaners/accelerators: Flange sealants are suitable for sealing charger housing joints, with good waterproof and temperature resistance; Thread locking agents are used for sealing and locking fasteners such as screws, while also providing aging resistance; Cleaners/accelerators are used for surface pretreatment before construction to improve adhesive layer adhesion. The overall solution can meet the core requirements of charger sealing.
Construction and Testing Recommendations
Before construction, clean the sealing surface with Airosen cleaner/accelerator to remove impurities such as oil and dust, ensuring a tight bond between the adhesive layer and the substrate. During construction, control the adhesive layer thickness and adjust the adhesive amount according to the gap of the sealing part to avoid adhesive overflow or insufficient sealing. For testing, waterproof immersion tests, high-low temperature cycle tests, and accelerated aging tests can be conducted to verify whether the sealing effect meets product usage standards.
Procurement Communication Points
When purchasing, clearly inform Airosen's technical team of the specific type of charger, sealing parts, and usage environment parameters (such as operating temperature range, humidity level) to obtain precise adhesive selection recommendations. Additionally, services such as construction process guidance and sample trials can be discussed to ensure the solution can be quickly implemented to meet production needs.
