Description
Technical Field
The utility model relates to an environment cabin field, specifically speaking, in particular to environment cabin is with aerifing sealing device.
Background
The environmental chamber is a test device for reasonably simulating indoor environmental conditions, and under the operating conditions of the chamber, whether the formaldehyde emission of the artificial board meets the national standard or not is detected. The environmental chamber generally has larger chamber capacity, the chamber door is also larger, the requirement on the isolation effect with the environment is high, and the sealing requirement is high. The environmental chamber for releasing formaldehyde and VOC generally requires that the leakage rate is not more than 1% (flow comparison method). Most of the existing cabin door sealing structures of the environmental cabins adopt sealing strips, and the sealing performance of the sealing strips has an improved space.
