As an indispensable bridge between electronic devices, connectors carry the heavy responsibility of signal transmission and power flow. A good connector not only requires stable transmission performance, excellent durability, and good compatibility, but also needs to maintain its outstanding performance in various extreme environments. The salt spray test was born to verify the corrosion resistance of connectors under high salinity environmental conditions.
Salt spray experiment
Salt spray test is an environmental test that mainly uses artificial simulated salt spray environmental conditions created by salt spray testing equipment to assess the corrosion resistance of products or metal materials. Compared with the natural environment, the chloride salt concentration in its salt spray environment can be several times or tens of times higher than the salt spray content in general natural environments, greatly increasing the corrosion rate and shortening the time to obtain results.
The earliest and most widely used salt spray method is the neutral salt spray test (NSS test), so what is its charm?
1. Ensure performance
Through neutral salt spray experiments, the corrosion resistance of products or metal materials in specific environments can be understood, ensuring that products can maintain stable and reliable performance in complex environments.
2. Guide optimization
The results of the salt spray test can guide us in optimizing product design, material selection, manufacturing processes, and other aspects, effectively improving the corrosion resistance of the product, thereby enhancing its anti-corrosion performance and durability.
3. Enhance trust
The results of the salt spray test can serve as an important basis for judging product quality, helping customers understand the corrosion resistance and service life of the product. This helps to enhance consumers' trust in the product, improve the brand image and market competitiveness of the enterprise.
Therefore, for enterprises pursuing high quality, conducting salt spray testing is an essential step!
What details cannot be ignored in the NSS salt spray experiment? Let's take a look at Zhiheng's exclusive insights!
Firstly, we need to ensure that the experimental equipment is in good condition in order to fairly evaluate the corrosion resistance of the metal. Therefore, before the experiment, it is necessary to carefully check whether the functions of the equipment are normal, ensure that the spray system, temperature control system, etc. are in the best working condition, and do a good job in regular cleaning and corrosion capacity test verification.
Secondly, the configuration of salt solution is crucial. Excessive concentration may cause metals to surrender in a short period of time; Low concentration may also allow metals to "get away with it". Therefore, we need to strictly follow the standard configuration of salt solution (pH value between 6.5-7.2) to ensure that its concentration is just right.
Finally, safety always comes first. In the NSS salt spray test, we need to pay attention to issues such as electrical safety and safe use of chemical reagents. Before the experiment, gloves should be worn to reduce the impact of sweat on the test results of the sample. At the same time, it is necessary to comply with the rules and regulations of the laboratory and maintain its cleanliness and hygiene.
In some harsh environments, if the product has not undergone sufficient salt spray testing, metal parts may rust, peel off, circuits may be damaged, and even safety hazards may occur. Based on countless lessons learned, Zhiheng strictly follows the requirements of GB/T 2423.17-2008 and GB/T 10125 for salt spray testing, and has also formulated more stringent enterprise standards to further ensure the corrosion resistance of Jointlean connectors.
The NSS salt spray test is crucial for assessing the corrosion resistance of products, and the detection details also have a significant impact on the experimental results, playing an important role in the field of metal protection. Only by implementing strict testing standards and carefully operating every step can we ensure the accuracy and reliability of the experiment, test truly excellent products with corrosion resistance in complex environments, and satisfy customers.
