4 Groups Bally Permeameter For Raw Material Uppers , 6 Digit Display LCD

Introduction:

For raw material uppers, such as: leather, leather, cloth, etc., and cut the specimen, the specimen is placed on a wet floor, under a certain pressure to make repeated flexing action test. To detect material resistant to penetration index, absorbent insole and insole reconciliation adsorption capacity, or for the development of improved materials, waterproof the basis

Technical parameters:

1. The test tank, diameter 120mm width 50mm is placed on the roller test piece, by means of compression force: 80±5N

  spring or pneumatic system makes the test strip against the drum, the drum in both directions about a horizontal line to the amplitude of each       50mm scroll horizontally reciprocating displacement .

2. Cylinder reciprocating movement frequency 20 times / min, reciprocating displacement: 50±1mm

3. The test piece is fixed on one end of the drum, and the other end is fixed on the platform, so that the drum axis is always parallel to the two     ends of the test piece. Will be fixed on the fixing roller pressing spring hooked piece with the other, the spring hook with a slight stress test strip     test pieces in order to avoid wrinkles.

4. The platform surface roughness 25μm, top lined with 3 to 5 layers of cotton cloth, by pipeline through the platform surface slowly out of the water  to keep moist. Flow rate: 7.5±2.5ml/min

5. The instrument is equipped with indication of water penetration audible alarm devices.

6. Timer: LED, accurate to 0.01s, 1 ~ 100hr.

7. Counter: 6 digit display LCD.

8. Die (Optional): conform cut (110±1)mm, width (40±1)mm of die cutter.

9. Number of specimens: 4 groups.
