Smart sensor trash bin will help you to enjoy the quality and convenient life very easily. You could easily feel the convenience that intelligent technology brings to us. You could easily control the trash bin's opening by wave your hands upon the sensor screen 15-25cm and it will soft close automatically after 5 seconds count down. Or you could easily openthe lid by your foot to kick the bin body softly and also the lid will soft close after 5 seconds counting down. E-motion induction trash can will help you to rest your hands by its perfect infrared sensor and vibration sensor technology. What's more, this electric garbage can is also designed with lid stay open function that if you have to throw the rubbish for a while, you could press the "open" button on the screen to make the lid keep open and it won't close until you press the "close". (Or it will close automatically after five minutes.) So this sensor trash bin will help you throw the trash much cleaner, more effectively and more convenient.

Application range of heat aging test chamber GB/T7141
The GB/T 7141-2008 standard outlines the procedure for conducting thermal aging tests on plastics exposed to hot air at various temperatures over long periods. This method focuses solely on the exposure conditions and does not define specific test methods or sample preparation. As a result, any property of the plastic that is affected by heat can be evaluated using appropriate testing procedures and suitable samples. The standard recommends using ASTM D3826 to determine the embrittlement endpoint, which occurs when the initial strain rate is set at 0.1 mm/min. The embrittlement endpoint is reached when 75% of the tested samples exhibit an elongation at break of 5% or less.
The GB/T 7141 heat aging test chamber provides a framework for comparing the thermal aging performance of different materials, based on changes in key properties such as embrittlement, which is typically measured by the reduction in elongation. This method is particularly useful for evaluating plastics that are prone to oxidation during use. It allows manufacturers and researchers to assess how well a material withstands prolonged heat exposure, which is crucial for applications where durability under high temperatures is essential.
It's important to note that the results obtained from this standard can vary depending on the type of heat aging chamber used. There are two main methods: Method A, which uses a gravity convection chamber, and Method B, which employs a forced ventilation chamber. Both methods are valid for exposing samples to heat, but the results from each should not be compared directly. Choosing the right chamber depends on the specific requirements of the test and the characteristics of the material being evaluated.
Understanding the application range of the heat aging test chamber according to GB/T 7141 helps ensure accurate and reliable results. Whether you're working with flexible polymers or rigid thermoplastics, selecting the correct testing environment is key to obtaining meaningful data about thermal stability. This standard plays a vital role in quality control, product development, and material selection across various industries.
