Where can I find a factory to customize inflatable sealing rings for sealed cabinets? Look no further than Qingtu Rubber. Specializing in the research and production of inflatable sealing rings, we boast over 1200 successful project development experiences, aiding numerous companies in their automation upgrade and transformation. Our extensive production and development expertise, combined with specialized technical guidance from our engineers, has earned us high praise from our cooperative clients. Sealed cabinets are categorized into positive pressure sealed cabinets and negative pressure sealed cabinets based on the pressure inside the cabinet.Testing has proven that after inflation sealing, the sealed cabinet has significantly improved in terms of sealing, strength, heat insulation, and sound insulation. The inflation sealing gasket is made of silicone rubber, which boasts excellent environmental protection and weather resistance. The inflation sealing ring of the sealed cabinet is the executing mechanism of the cabinet's control system, and the sealing requirement of the cabinet relies on inflation to exert the sealing function. Due to the flexibility of silicone rubber, the hollow ring expands plastically after inflation. Upon contact with the sealing surface, it undergoes flexible curve deformation, allowing it to seal gaps around the door in either straight or curved shapes. After deflation, the sealing ring instantly returns to its original shape, restoring the equipment gap. It can quickly achieve both sealing and unsealing, with frequent inflation and deflation capable of reaching 100,000 cycles. In the working state, the internal gas pressure of the ring body exerts a force, resulting in high sealing strength and thus excellent sealing performance. Currently, the sealed cabinets have been well applied in projects requiring high air tightness in high-level biosafety laboratories, disinfection rooms, isolation rooms, and other health and safety fields.

1. Inflatable Seal Strip Material: Silicone.
2. Inflatable seal strip hardness: 60-70.
3. Environmental temperature adaptability: -30℃ to 200℃.
4. Inflatable Seal Strip Inflation and Deflation Test: Inflation pressure 2.0 kg/cm to 3.0 kg/cm, inflation time <5 seconds, deflation time <5 seconds, repeated over 5000 times, no bursting or leakage.
5. Monitoring System: Monitors air pressure of inflatable sealing strips, status of air-tight door opening/closing, and timing of door operations. Can be displayed and alarmed via a central control system.
6. The door can automatically close, with automatic inflation and deflation upon closing and opening. It can also be manually controlled for inflation and deflation.
The inflatable sealing strips are embedded in the grooves of the door frame. Their operation principle is as follows: when the door is opened, the inflatable sealing strip releases air and shrinks within the groove. When the door is closed, the inflatable sealing strip inflates to create a tight seal between the door and the frame, while the door is securely locked, achieving the sealing effect.
