Beijing Yashilin high and low temperature test chamber sealing system uses double-layer high temperature resistant silicone rubber sealing strip. Its function is mainly to seal the test box door, so that the outside air does not intrude into the box, and the gas inside the box does not escape. However, after the customer buys the high and low temperature test chambers, few people know how the seals of the high and low temperature test chambers should be maintained. After investigation, 90% of the high and low temperature test chamber seals were faulty due to the user not properly maintaining it. Therefore, once the high and low temperature test chamber door seals are found to be poorly sealed, they should be repaired in time. (1) For the high and low temperature test chambers that have been used for many years, the silicone rubber has been aged and the new seals should be replaced in time. (2) If the door seal is slightly deformed and the surface is not straight, loosen the screw that fixes the magnetic door seal, insert a thin rubber under the gap, and then retighten the screw. If the door is closed and not parallel to the box, adjust the bracket of the fixed box door (or the upper and lower door frame pivots) and adjust as much as possible until the box door is closed and parallel to the box. (3) Because the door seal has a certain magnetic force, the door seal is easy to adsorb iron scrap or ferroalloy powder, so that the door is not closed tightly, and the door seal is worn out. It is found that the iron scrap and metal powder should be used in time with a rag. Wipe off. Note: When wiping the residual water in the plastic edge of the door seal, be careful to open the plastic edge and wipe it gently with a clean soft cloth. Never break the plastic magnetic strip. When the high and low temperature test chambers are left unused for a long time, apply a small amount of talcum powder on the door seal, keep it dry, and put it in a cool and ventilated place. An easy way to check the tightness of the door seals of high and low temperature test chambers: 1 Close the door, use a thin strip of paper, insert it vertically into any part of the door seal, the paper strip should not slide freely; 2 will be on the high and low temperature box observation window Turn on the light, close the door, and check for light leakage around the door seal.
