Introduction
Zinc alloy handles are widely used in various industries due to their excellent mechanical properties, such as high strength and wear resistance. However, their waterproof and moisture resistance performance is still a challenge, which limits their application in outdoor environments. In this article, we will discuss the research and improvement of the waterproof and moisture resistance performance of zinc alloy handles.
Research Methods
1. Preparation of zinc alloy handle samples: Zinc alloy handle samples were prepared by die-casting technology.
2. Waterproof test: The waterproof test was carried out by immersing the samples in water for a certain period of time, and then checking the appearance and weight change of the samples.
3. Moisture resistance test: The moisture resistance test was carried out by placing the samples in a high humidity environment for a certain period of time, and then checking the appearance and weight change of the samples.
4. Surface treatment: Different surface treatments, such as electroplating and anodizing, were applied to improve the waterproof and moisture resistance performance of the zinc alloy handles.
Improvement of Performance
5. Surface treatment: Electroplating with a layer of nickel or chrome can effectively improve the waterproof and moisture resistance performance of zinc alloy handles. Anodizing with a layer of aluminum oxide can also achieve the same effect.
6. Modification of material composition: Adding a small amount of copper or nickel to the zinc alloy can improve its corrosion resistance and thus improve the waterproof and moisture resistance performance of the handles.
7. Optimization of die-casting process: The optimization of the die-casting process, such as adjusting the die temperature and injection speed, can also improve the waterproof and moisture resistance performance of zinc alloy handles.
