Introduction
Embedded handles are widely used in various fields, such as transportation, construction, and furniture. However, in cold environments, the handles may crack or break due to the low temperature. Therefore, it is essential to study the anti-freeze and cold resistance performance of embedded handles to improve their durability and reliability.
Experimental Method
1. Sample preparation: We made embedded handles with different materials, including plastic, metal, and composite materials.
2. Anti-freeze test: We placed the samples in a low-temperature environment (-20℃) for 24 hours, then took them out and observed any cracks or breaks.
3. Cold resistance test: We used a universal testing machine to apply a gradually increasing load to the samples at a low temperature (-20℃) until they broke.
4. Data analysis: We recorded the anti-freeze and cold resistance performance of each sample and analyzed the data to compare the differences between different materials.
Results and Discussion
1. Anti-freeze performance: The plastic handle showed the worst anti-freeze performance, with cracks appearing after 24 hours in the low-temperature environment. The metal handle had a better anti-freeze performance, with no cracks or breaks observed. The composite material handle had the best anti-freeze performance, with no visible damage after 24 hours.
2. Cold resistance performance: The plastic handle had the lowest cold resistance performance, with a load of only 10kg before breaking. The metal handle had a better cold resistance performance, with a load of 30kg before breaking. The composite material handle had the best cold resistance performance, with a load of 50kg before breaking.
3. Material selection: Based on the experimental results, the composite material is the best choice for embedded handles in cold environments, due to its excellent anti-freeze and cold resistance performance.
