How to evaluate the wear resistance and waterproof performance of pe wristband?
Publish Time: 2025-03-06
As a common identification and wearable product, pe wristband is widely used in many fields such as medical treatment, event management, and entertainment venues. Its wear resistance and waterproof performance are important indicators for evaluating the quality of pe wristband, which are directly related to the service life and practicality of the wristband. This article will introduce in detail the evaluation method of the wear resistance and waterproof performance of pe wristband.
1. Wear resistance evaluation method
Wear resistance is an important parameter to measure the ability of a material to resist wear. For pe wristband, wear resistance is directly related to its service life and appearance retention. There are mainly the following methods to evaluate the wear resistance of pe wristband:
Friction and wear test: This is the most commonly used evaluation method. By simulating the friction conditions in actual use, the pe wristband is tested using a friction and wear tester. During the test, the mass loss, thickness change or surface morphology change before and after wear are recorded to evaluate the wear resistance of the wristband. The results of the friction and wear test are usually expressed as wear rate or friction coefficient. The smaller the wear rate, the better the wear resistance.
Falling sand wear test: This method evaluates the wear resistance of pe wristband in harsh environments by simulating the impact and wear of sand on the material. A certain amount of sand is dropped from a certain height to impact the surface of pe wristband, and the wear is recorded.
Actual use test: Wear pe wristband for a long time in a specific environment, such as outdoor activities, medical environment, etc., observe and record its wear. Although this method is time-consuming, it can more truly reflect the wear resistance of the wristband in actual use.
2. Waterproof performance evaluation method
Waterproof performance is an important guarantee for the use of pe wristband in specific occasions (such as water activities, rainy days, etc.). There are mainly the following methods to evaluate the waterproof performance of pe wristband:
Static immersion test: immerse the pe wristband completely in water for a certain period of time (such as 24 hours), and then take it out to check whether there is water penetration. This method is simple and intuitive, and can preliminarily evaluate the waterproof performance of the wristband.
Dynamic spray test: simulate the impact of rain or water on the wristband, and use a spray device to spray the pe wristband. Observe and record whether water penetrates into the wristband to evaluate its waterproof performance. This method is closer to actual use and can more comprehensively evaluate the waterproof performance of the wristband.
Pressure test: For occasions that need to withstand high water pressure, such as diving, pressure testing can be performed. Place the pe wristband in a high-pressure environment and observe and record its waterproof performance. This method can evaluate the waterproof performance of the wristband under extreme conditions.
The wear resistance and waterproof performance of the pe wristband are important indicators of its quality. Its wear resistance can be evaluated by friction and wear tests, falling sand wear tests, and actual use tests; its waterproof performance can be evaluated by static immersion tests, dynamic spray tests, and pressure tests. During the evaluation process, it is necessary to select appropriate test methods and standards according to specific use occasions and needs to ensure the accuracy and reliability of the evaluation results. At the same time, manufacturers should strictly control the quality of raw materials and production process to improve the wear resistance and waterproof performance of pe wristbands to meet market demand.
