Description

Technical Field

[0001] The utility model belongs to the technical field of electrical performance detection, and in particular relates to an odd-numbered nylon electrical performance testing device. Background Art

[0002] Nylon (polyamide) is the earliest industrialized polymer material with a history of more than 50 years. It is widely used in machinery, transportation, electrical, chemical, textile and daily necessities due to its low specific gravity, wear resistance, oil resistance, easy processing and excellent mechanical properties. So far, nylon is mainly used as engineering plastics or fiber products. The varieties with large output are nylon 6, nylon 66, nylon 1010, etc. However, in recent years, the research on the special electrical properties of odd-numbered nylons (such as nylon 11, nylon 7, nylon 5, etc.) shows that odd-numbered nylons have excellent ferroelectric, thermoelectric, piezoelectric and dielectric properties, and have broad application prospects as electronics and sensors.

[0003] Therefore, it is very necessary to accurately understand the electrical properties of odd-numbered nylon, that is, it is necessary to conduct physical tests on its electrical properties to avoid failures during use and cause unnecessary economic losses.

[0004] However, most traditional semi-electrical performance physical devices can only perform tests under one environment, and cannot comprehensively test the overall performance of odd-numbered nylon, and cannot adapt to the use requirements under multiple environments. Therefore, an electrical performance testing device is needed to perform more comprehensive tests on odd-numbered nylon under multiple environments in order to accurately understand the electrical properties of odd-numbered nylon.
