Application of Humidity Chamber in damp heat resistance of steel plate

Abstract: 本文讲述了恒温恒湿试验箱在钢板耐湿热性测试中的应用。钢板在建筑和制造中广泛使用,但在高温潮湿环境中容易生锈和腐蚀,影响其寿命。为了评估钢板的耐久性和可靠性,需要进行耐湿热试验。这种测试通过模拟高温高湿条件,检测钢板的抗腐蚀性能和表面处理质量。试验方法包括样品准备、设置试验箱的温度和湿度、进行测试、取样后检查外观和性能变化,并根据结果评估钢板的耐湿热性能。文章还提醒,钢板性能测试可能需结合其他测试方法,如盐雾腐蚀测试,以全面评估其性能。

As a commonly used building material, steel plates are widely used in building structures, such as walls, roofs, stairs, railings, etc. At the same time, steel plates are also used in the manufacture of various mechanical equipment, auto parts, electrical equipment, etc. During use, the steel plate will be affected by various environmental factors, such as high temperature, humidity, etc. These factors will cause problems such as rust and corrosion on the surface of the steel plate and reduce its service life.

Therefore, in order to ensure the durability and service life of the steel plate, it is necessary to conduct a damp heat test. By testing in a high-temperature and high-humidity environment, the environmental conditions in actual use can be simulated, and the corrosion resistance and surface treatment quality of the steel plate in a humid and high-temperature environment can be tested to evaluate its durability and reliability. Steel plates are used for specific applications.

The application of the constant temperature and humidity Test Chamber in the heat and humidity resistance of the steel plate is shown in Fig. 1

experiment method

The application and test method of the damp heat Test Chamber in the damp heat resistance test of the steel plate are as follows:

  1. According to the test requirements, the steel plate is cut into samples of specified size, cleaned and dried.

  2. Place the sample in a damp heat Test Chamber and set corresponding temperature and humidity conditions, such as 40°C, 95%RH.

  3. The test is given for a specified period of time, usually 48 hours or more.

  4. Take out the sample and conduct appearance and performance tests, such as measuring its thickness change, weight change, tensile strength and other indicators, and observing whether there is oxidation or corrosion.

  5. Evaluate the damp heat resistance performance of the steel plate according to the test results.

NBCHAO reminds you: the performance test of the steel plate may also require other tests, such as salt spray corrosion test, hardness test, etc., to fully evaluate its performance.
