TQD-G1 Air permeability tester is professionally designed for the determination of air permeability of decorating materials used in cars, e.g. polyurethane, expanded plastics, PVC, leather, textiles, nonwovens and other materials. Through the test, physical characteristics of materials could be controlled to meet practical application requirements.
|Test Range of Pressure||0 ~ 1000 Pa|
|Test Range of Flux||0 ~ 30 L/min|
|Specimen Size||Method A: 52 mm x 52 mm|
Method B:Φ12 mm ≤ D(diameter) ≤ Φ71 mm
|Port Size||Φ8 mm PU Tubing|
|Instrument Dimension||502 mm (L) x 334 mm (W) x 298 mm (H)|
|Power Supply||220VAC 50Hz / 120VAC 60Hz|
|Net Weight||27 kg|
Providing a constant air flux going through the specimen vertically, the air permeability could be obtained by measuring the pressure difference.
Providing the constant pressure difference between two sides of the specimen, the air permeability could be obtained by measuring the air flux through specific area in the certain time.
TQD-G1 air permeability tester is applicable to the determination of:
Test the air permeability of car decorating materials, e.g. polyurethane, PVC, leather, textiles and nonwovens materials
Test the air permeability of elastic and porous polymer materials, e.g. sponges
Test the air permeability of textiles, e.g. cloth and nonwovens
Test the air permeability of leather
Test the air permeability of paper materials, e.g. daily removable tissue and toilet rolls
