    Door sealing and maintenance experience of high and low temperature alternating wet and hot box


    High and low temperature alternating humidity and heat box is suitable for electrical, electronic, instrumentation and other products, components and materials in the high and low temperature alternating humidity and heat environment storage, transportation, and adaptability tests. High and low temperature alternating humidity and hot box simulation products are used in the defense industry, aerospace industry, and automation components under the combined conditions of high temperature and low temperature (high and low temperature operation & storage, temperature cycling, high and high humidity, low and low humidity, and condensation tests). , Automotive parts, electronic and electrical components, instruments, materials, plastics, chemicals, food, pharmaceutical industry and related products of heat resistance, humidity resistance, cold resistance, dry resistance and quality management engineering test specifications. Under the environmental conditions, test whether the adaptability and characteristics of the product itself are changed.
    After long-term use of the high and low temperature alternating humidity and heat box, the silicone rubber is found to be aging. If it is not replaced in time, it will directly affect the cooling effect and power consumption of the high and low temperature alternating humidity and heat box. How to repair it?
    Here are two maintenance experiences:
    1. Hair dryer heat setting method
    If the high and low temperature alternating wet and hot box door seal is S-shaped, you can use a ruler to pad the inside of the door seal, and then use a hair dryer to slightly heat the curved part. When the plastic is slightly bent, stop heating. Wait for high and low temperature After the alternating hot and humid box door seal is cooled, the ruler can be restored to its original shape when the ruler is pulled out. It must be noted that when using a hair dryer for heating, the temperature must not be too high, otherwise the door seal plastic will be baked, deformed, and deformed.
    2. Hot water immersion setting method
    If the high and low temperature alternating wet and hot box door seal is aging and deformed, the silicone rubber sealing strip on the box door can be pulled out, as long as the deformed door sealing strip is immersed in hot water at about 60 ° C. Flip from time to time. Remove it after 7-8 minutes and put it straight on the flat surface by hand. If the door seal is still not straight after cooling, you can repeat the process as described above.
