Low/high Temperature Test Chamber for powder coatings

application

Powder coatings are widely used in the surface coating of various metal products to improve the corrosion resistance, wear resistance and aesthetics of metal products. During use, powder coatings may be affected by different temperature environments, so high-low temperature resistance tests are required.

The high-low temperature resistance test can simulate the high temperature and low temperature in the actual use environment, and detect the performance of powder coatings under these conditions, such as corrosion resistance, wear resistance, color stability, adhesion, etc., to judge its performance. Whether it meets the design requirements, so as to ensure its reliability and stability.

In addition, the high-low temperature resistance test can also evaluate the temperature adaptability range of powder coating materials, helping manufacturers or users to choose more suitable materials to adapt to different environmental conditions, thereby improving product performance and service life.

In short, the high-low temperature resistance test is carried out to ensure that the powder coating can work normally under various environmental conditions, and it can also provide a reference for product design and material selection.

experiment procedure

The high-low Temperature Test Chamber can be used to test the durability of powder coatings in high-low temperature environments. The following are the general test steps:

1. Sample preparation: Prepare the powder coating sample to be tested and evenly coat it on the test panel. Coatings can be applied in different thicknesses and application methods as required.

2. Test parameter setting: set the temperature and time parameters of the high-low Temperature Test Chamber. Usually, the temperature range of the high-low temperature test is -70°C to +150°C, and the duration can range from several hours to tens of hours.

3. Load the sample: place the test panel coated with powder coating in the high-low Temperature Test Chamber, and ensure that the sample is securely fixed.

4. Carry out high temperature test: set the temperature of the Test Chamber to a high temperature value and keep it for a period of time. During this time, the coating should withstand the high temperature environment without any failure.

5. Conduct low temperature test: set the temperature of the Test Chamber to a low temperature value and keep it for a period of time. During this time, the coating should withstand the low temperature environment without any failure.

6. Observation results: After completing the high-low temperature test, observe whether there are any cracks, peeling or other failure phenomena on the surface of the coating. Equipment such as a microscope, magnifying glass, etc. can be used to examine the details of the coating.

7. Result analysis: According to the test results, evaluate the high-low temperature resistance performance of the coating, and formulate corresponding improvement measures.

NBCHAO reminds you: Before conducting high-low temperature tests, the high-low Temperature Test Chamber should be calibrated and verified to ensure the accuracy and reliability of the test results.
