The working principle of inflatable sealing strips is a device that achieves sealing effect through internal inflation. It is usually made of high-strength, aging resistant elastic material, with an inflation chamber inside, which adjusts the tightness of the seal by controlling the air pressure. When the door is opened, the inflatable sealing strip deflates and contracts in the groove; When the door is closed, the inflatable sealing strip inflates and expands to form a strict seal between the door and the door frame.
The application fields of inflatable sealing strips are very wide, mainly including the following aspects:
Aerospace: Inflatable sealing strips can effectively isolate external air, moisture, and dust in critical areas such as aircraft doors and fuel tank covers, ensuring flight safety.
Biosafety Laboratory: In high-level biosafety laboratories, medical rooms, disinfection rooms, isolation rooms, and other environments that require air flow inside and outside the isolation room, inflatable sealing strips can automatically inflate and deflate according to the sealing condition of the door leaf and door frame, ensuring a tight fit with the door frame and forming a complete sealing layer.
• Factory and warehouse: used to fill the gap between trucks and doorways, prevent air flow and heat loss, and prevent mosquitoes and other pests from entering the cargo stacking area.
Large cabin doors and hatches: used to fill the gaps between large cabin doors and hatches, adapting to the thermal expansion and contraction deformation caused by environmental temperature changes.
Automotive industry: Inflatable sealing strips are installed in key areas such as doors, windows, engine hood, and trunk, effectively isolating external noise, dust, and moisture from entering, and improving the vehicle's air and water tightness.
In the construction industry, inflatable sealing strips can prevent the exchange of hot and cold air, reduce energy consumption, and improve the insulation performance of buildings in building doors, windows, curtain wall systems, and roof structures.
Cold chain logistics: Installing inflatable sealing strips in key areas such as refrigerated trucks and cold storage doors can ensure stable and sealed refrigeration environments, extending the shelf life of sensitive goods such as food and drugs.
Chemical industry: Used for frequently opened and closed pipeline ports and valves, such as crushers, dryers, and other equipment, which can simplify the installation process and improve sealing effectiveness.
Food packaging: In the automated canning process of plastic bags for powdered food, the use of inflatable sealing strips can improve canning efficiency and ensure packaging sealing.
