Product Description

Equipment use:

GB/T15171-94 flexible packaging products in accordance with the sealing performance of the test method design and manufacture of the relevant provisions applicable to food, pharmaceutical, the flexible packaging industry, such as the sealing test. Through experiments can be effectively compare and evaluate the sealing process of flexible packaging and sealing performance, and to identify the associated technical requirements provide a scientific basis. Can be carried out by the fall, after the pressure of a tightness test specimen.

Basic tenets:

Goods to the source of compressed air as the driving force, the latest plastic vacuum generator for energy conversion devices, vacuum table for visual display means, through the vacuum pressure control to achieve faster, visual effects, such as rapid test excellent performance. Pneumatic system components used in all Germany imported products, stable performance, extremely reliable operation, and within three years without maintenance. Improve the function of settings, a variety of vacuum to meet national standards for various test methods require.

Specifications:

30s can be achieved within the set vacuum.
Measurement Range: -0.90-0 bar
Test tube plot: φ270 mm × 490mm
Compressed air pressure of 0.8 MPa :0.2 -

Additional gas separation device, remove impurities interference, and long life.

Test principle:

Through the vacuum chamber time, immersed in the water pressure inside and outside a sample observed in the gas sample, Yi, to determine sample sealing performance: the vacuum chamber or through time, the pressure inside and outside a sample, Observing expansion and the release of the sample after sample shape recovery vacuum, to determine sample sealing performance.
