Testing the corrosion resistance of tungsten wire for textiles weaving gloves is the key to ensure its long-term use in corrosive environments. The following are common test methods and steps:
- Salt Spray Test
Method:
Sample preparation: Process the tungsten wire sample into standard specifications and clean it to remove any surface contaminants.
Test equipment: Salt spray test chamber.
Test steps: Place the sample in the salt spray test chamber, and the environment in the chamber is set to high concentration salt spray (usually 5% sodium chloride solution) and high humidity. The sample is exposed to this environment for a certain period of time (such as 24 hours, 48 hours, etc.).
Data analysis: Check the corrosion degree of the sample and evaluate the corrosion resistance of the tungsten wire. Record the appearance changes of the sample after the salt spray test, such as rust, pitting, etc.
- Immersion Test
Method:
Sample preparation: Prepare the tungsten wire sample into standard size and ensure its surface is clean.
Test equipment: Corrosion resistance test container (such as plastic or glass container) for placing samples and corrosive media.
Test steps: Immerse the sample in a corrosive liquid (such as acidic or alkaline solution, salt water, etc.) and keep it at a specific temperature for a certain period of time (such as several hours, several days, etc.).
Data analysis: After taking out the sample, check its surface changes, measure the mass loss of the sample, the generation of corrosion products and the degree of surface damage.
- Electrochemical Corrosion Test
Method:
Sample preparation: The tungsten wire sample needs to be prepared into the standard shape and size of the electrochemical test.
Test equipment: Electrochemical workstation, including reference electrode, counter electrode and working electrode.
Test steps: Place the sample as a working electrode in an electrolyte containing a corrosive medium, and apply current or voltage to simulate actual corrosion conditions. Evaluate the corrosion behavior of the sample through electrochemical measurements (such as potential polarization curves, AC impedance).
Data analysis: Analyze electrochemical data to determine the corrosion rate and corrosion mechanism of the tungsten wire. Evaluate its corrosion resistance.
- Atmospheric Corrosion Test
Method:
Sample preparation: Prepare the tungsten wire sample into the test specifications.
Test equipment: Atmospheric corrosion test chamber.
Test steps: Expose the sample to a simulated corrosive atmosphere, such as industrial gas, moisture, acidic gas, etc. The test time can range from a few hours to a few weeks.
Data analysis: Check the surface changes of the sample, such as corrosion spots, color change, etc., and record the corrosion rate.
- High-Temperature Corrosion Test
Method:
Sample preparation: Tungsten wire samples need to be prepared into standard sizes.
Test equipment: High-temperature furnace or high-temperature corrosion test equipment.
Test steps: Expose the sample to corrosive gas or liquid, such as oxidizing gas, acidic gas, etc., under high temperature environment.
Data analysis: Evaluate the corrosion resistance of the sample in a high-temperature corrosive environment and observe whether there is oxidation, corrosion or material performance degradation.
Precautions
Test conditions: Ensure that the conditions of the test environment (such as temperature, humidity, and atmosphere) meet the corrosion environment in actual applications.
Sample preparation: Before testing, ensure that the surface treatment and pretreatment of the sample meet the standards to avoid external factors affecting the test results.
Data recording: Record the data and observations of each test in detail, including the corrosion degree and mass loss of the sample.
Through these test methods, the corrosion resistance of tungsten wire for textiles weaving gloves in various corrosive environments can be systematically evaluated to ensure its reliability in actual applications.
