The single-leaf stainless steel waterproof vault (cultural relics vault) door plays a vital role in places with strict waterproof requirements such as cultural relics vaults. The extremely humid environment is a huge test for the waterproof sealing performance of the vault door. The design and performance of its waterproof sealing structure are directly related to whether it can effectively protect valuables such as cultural relics in the vault from moisture.
The waterproof sealing structure of the single-leaf stainless steel waterproof vault (cultural relics vault) door first relies on high-quality sealing materials. High-performance rubber materials such as silicone rubber and EPDM rubber are usually used as sealing strips. These materials have good elasticity, aging resistance and water resistance. In extremely humid environments, they can maintain stable physical properties and are not easy to deform, crack or harden. Even in a high-humidity or even water-stained environment for a long time, the sealing strip can still fit the door body and the door frame tightly, effectively preventing moisture from penetrating.
In order to enhance the waterproof effect, the vault door adopts a multiple sealing structure. Generally, it includes a circle of main sealing strips around the door frame, and auxiliary sealing strips between the door body and the door frame. The main sealing strip is usually installed in the groove of the door frame. When the door is closed, the door body squeezes the strip to form the first waterproof barrier. The auxiliary sealing strip is located at the edge of the door body, further filling the slight gap between the door body and the door frame to form the second line of defense. This multiple sealing structure can effectively deal with the problem of poor sealing caused by factors such as door body deformation and installation error, and minimize the possibility of moisture entering the vault in extremely humid environments.
The installation process of the sealing strip also has an important impact on the waterproof performance. During installation, it is necessary to ensure that the strip is flat and not twisted, and fits tightly with the door frame and door body without gaps. Special glue or card slots are usually used to fix the strip to prevent it from shifting or falling off during use. At the same time, a special splicing process, such as hot vulcanization splicing, is used at the interface of the strip to form a whole, avoiding gaps from becoming water seepage points. Through precise installation technology, it is ensured that the sealing strip can always maintain a good sealing state in extremely humid environments.
In addition to the sealing structure, the waterproofing of the single-leaf stainless steel waterproof vault (cultural relics vault) door is inseparable from the synergy of the drainage system. Drainage grooves or drainage holes will be set at the bottom of the door frame or around the door body. When a small amount of water penetrates through the sealing strip, the drainage system can guide the water out in time to prevent the accumulated water from damaging the door body and the sealing structure. The drainage groove is usually designed with a certain slope to ensure that the water can flow smoothly to the drainage hole, and the size and number of the drainage holes are reasonably calculated to meet the drainage needs in extremely humid environments.
The door body structure of the single-leaf stainless steel waterproof vault (cultural relics vault) door itself also has a certain waterproof ability. The stainless steel door body has good corrosion resistance and waterproofness, and its surface has been finely processed and smooth, reducing the possibility of water adhesion and penetration. At the same time, the internal structure of the door body adopts a sealed design to prevent water from entering the vault through the internal gaps of the door body. For example, filling the interlayer of the door body with waterproof insulation materials can not only enhance the thermal insulation performance of the door body, but also further prevent water penetration.
In order to ensure that the waterproof sealing structure always maintains good performance in extremely humid environments, regular maintenance and inspection are essential. Regularly check the wear of the sealing strips and replace aging or damaged strips in a timely manner. At the same time, clean up the debris in the drainage system to ensure smooth drainage. In addition, the overall waterproof performance of the door body will be tested, such as through water pressure testing and other methods to promptly discover and repair potential leaks. Through regular maintenance and inspection, it can ensure that the waterproof sealing structure of the single-leaf stainless steel waterproof vault (cultural relics vault) door continues to play an effective waterproof role in a long-term extremely humid environment, providing reliable protection for valuables such as cultural relics in the vault.
