How to repair the high and low temperature alternating heat and humidity test box door seal How to repair the high and low temperature alternating damp heat test box After a few years of use, some of the silicone rubber has been aged. If it is not replaced in time, it will directly affect the cooling of the high and low temperature alternating damp heat test box. The effect and power consumption are also likely to cause the compressor to burn due to repeated start-up. So how do you repair it yourself? other AST Industry Co.,LTD , https://www.astsoundchip.com
(1) Heat setting method for hair dryer: If the door seal of the high-low temperature alternating humidity test chamber is S-shaped, it can be lining the inner side of the door seal with a long-sized foot pad, and then slightly heated with the hair dryer against the curved part until the plastic slightly When heating is stopped, the heating is stopped, and after the cooling of the door seal of the humidity-heating test box is cooled, a ruler can be pulled out to restore the door seal to its original state. It must be noted that when using a hair dryer to heat, the temperature must not be too high, otherwise the door seal plastic will be baked, sampled, and deformed.
(2) hot water immersion stereotypes method: such as high and low temperature thermostatic test chamber door seal aging deformation, can be on the door of the silicone rubber sealing strip out, as long as the deformation of the door seal put about 60 °C soaked in hot water. Turn it from time to time. Remove after 7-8 minutes and gently straighten on a flat surface. After cooling, if the door seal is still not straight, repeat the process as described above.
