WZY-120Waterproof roll bending tester

1、 Product Introduction:

Waterproof roll bending tester, used for low-temperature bending test of polymer rolls and waterproof coatings. The bending instrument is mainly composed of upper and lower plates made of metal materials, a rotating shaft, a shaft support, and a distance adjusting screw. The bending instrument is mainly composed of upper and lower plates made of metal materials, a rotating shaft, and a distance adjusting screw. The spacing between the tablets can be adjusted freely.

IIWaterproof roll bending testerMain technical parameters:

1Test piece size:100×50mm

2Bending angle:180°

3、 Usage:

1Under standard conditions, use the prescribed thickness gauge(thickness gauge)Measure the thickness of the sample.

2Take samples in both the horizontal and vertical directions of the specimen100×50/50×100mmTwo samples.

3The thickness resistance of the sample in seconds and years Facing outward, curved180°, make50mmThe wide edges overlap, are level, and ensure no misalignment occurs,(Available positioning clips or10nnSecure the edges with wide adhesive tape).

4, willWaterproof roll bending testerAfter adjusting the distance between the upper and lower plates to three times that of the tested coil, flip over the upper and lower plates of the bending instrument, and place two samples in the same direction on the lower plate of the bending instrument, with the overlapping side facing the axis and aligned with the scale line.

5Overall anti entry into the low-temperature box, maintained at the specified temperature1h,then1SFlip the upper tablet down to the adjusted spacing position and maintain it1SAfterwards, take out the sample.

6After returning to room temperature, observe whether the bending part of the sample is broken, or use magnification to observe whether the Lamian Noodles at the bending part of the sample is cracked

7Structural evaluation of low-temperature bending apparatus

8When both tests do not break or have no fracture marks, it is evaluated as no fracture.

9Note:(1)standardGB12592-2003(Polyvinyl chloride waterproof material)For example. The use of other materials should refer to the corresponding standards or industry standards for testing methods.
