Overhaul of high and low temperature alternating heat and humidity test box door seal

After several years of use, the high-low temperature alternating heat and humidity test chamber has some aging of silicone rubber. If it is not replaced in time, it will directly affect the cooling effect and high power consumption of the high and low temperature alternating heat and humidity test chamber. After using for a few years, some of the silicone rubber has been 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 heat and humidity test chamber, and it will easily cause the compressor to burn due to repeated starts. So how do you repair it yourself?
(1) Hair dryer heat setting method: If the door seal of the high and low temperature alternating heat and humidity test chamber is S-shaped, it can be lined on the inner side of the door seal with a straight foot pad, and then slightly heated by the hair dryer to the curved part, until the plastic is slightly When the bending is soft, the heating is stopped. After the door seal of the high and low temperature alternating heat and humidity test box is cooled, the door seal can be restored to the original state after the ruler is pulled out. It must be noted that when using a hair dryer to heat, the temperature should not be too high, otherwise the door seal plastic will be baked, sampled and deformed.
(2) Hot water soaking and setting method: If the door seal of the high and low temperature alternating heat and humidity test box is aging and deformed, the silicone rubber sealing strip on the door can be extracted, as long as the deformed door seal is placed in hot water of about 60 °C. Turning from time to time. Remove it after 7~8 minutes, and gently straighten it by hand on a flat surface. After cooling, if the door seal is still not straight, it can be repeated as described above. Overhaul of high and low temperature alternating heat and humidity test box door seals http://
