Regarding the door seal of the high and low temperature test chamber, we can maintain it according to the following methods:

1. For the high and low temperature alternating damp heat test chamber that has been used for many years, when the silicone rubber is aging, new sealing strips should be replaced in time.

2. When the seal of the door of the test chamber is slightly deformed and the surface is not parallel, you can unscrew the screw fixing the magnetic door seal, put a thin rubber in the gap, and then re-tighten the screw. If the door is not level with the box body after the door is closed, you can adjust the bracket that fixes the box door as far as possible until the box door is closed and parallel to the box body.

3. Because the seal of the test chamber door has a certain magnetic force, iron filings or ferroalloy powder are easily adsorbed on the door seal, which will cause the door to be not closed tightly, and will cause the seal to wear like a dream. When you find this phenomenon, you need to Wipe off iron filings and metal powder with a rag in time.

4. When wiping the remaining water in the edge of the seal material of the door of the high and low temperature cycle test chamber, be careful to open the plastic edge and wipe it gently with a clean soft cloth. Do not break the plastic magnetic strip. When the high and low temperature damp heat test box is not used for a long time, a small amount of talcum powder can be coated on the door seal, keep it dry, and place it in a ventilated and cool place.
