2024-12-17

With the advancement of industrialization, the use of weighing equipment is becoming increasingly widespread, from traditional market scales and car scales to dynamic weighing systems in modern intelligent logistics systems. The accuracy and stability requirements of weighing equipment are becoming higher and higher. As the core component of weighing equipment, the weighing sensor directly affects the accuracy of weighing results and the long-term stability of the equipment. Therefore, how to ensure that sensors are not affected by external environmental factors, especially moisture, dust, and other harsh conditions, during long-term use has become a major challenge in the weighing industry.Scale sensors typically use electronic components and sensor chips, which are highly sensitive and susceptible to moisture and external pollutants. Especially in humid environments, moisture may enter the interior through interfaces, causing circuit corrosion, performance degradation, and even damage to sensors. Therefore, encapsulation technology plays a crucial role as an effective protective measure in the production and maintenance of weighing sensors. Internal sealing of weighing sensorSealing materials not only need to isolate moisture and protect components, but also need to ensure good physical properties and chemical stability to avoid affecting the accuracy and lifespan of sensors due to environmental changes. More importantly, the sealed material needs to have easy peelability to facilitate equipment maintenance and repair. With the increasing demand for environmental protection and green materials, traditional sealing materials can no longer meet the requirements of modern industry. Finding a sealing material that is both environmentally friendly and efficient has become an urgent task.Challenge
