Operation of waterproof material bending instrument

Whether at work or in life, we will see the widespread use of waterproof materials. Jinan Hengsi Shanda Instrument Co., Ltd. has made a detailed analysis on the characteristics and scope of application of waterproof materials:

1, How to use:

A: Under standard environment, use a specified thickness gauge to measure the thickness of the sample.

B: Take the horizontal and vertical directions of the sample100×50/50×100mmTwo samples.

C: Bend the weather-resistant surface of the sample to the outside and bend180°, make50mmThe wide edges overlap flush and ensure no misalignment occurs.

D: After adjusting the spacing between the upper and lower plates of the bend meter to three times the coil to be measured, then open the upper and lower plates of the bend meter, place the two samples in the same direction on the lower plate of the bend meter, and the overlapping side is facing the rotation axis and placed in line with the scale line.

E: Place the whole in a low temperature box and keep it at the specified temperature1h,Then1sInside, turn the upper plate down to the adjusted spacing position to maintain1sAfterwards, remove the sample.

F: After returning to room temperature, observe whether the bend of the sample is broken, or use a magnifying glass to observe whether there are cracks in the ramen surface at the bend of the sample.

2. Scope of application; suitable for polyvinyl chloride and polyvinyl chloride waterproof coils; modified recycled rubber waterproof coils; and low-temperature bending instrument test and low-temperature flexibility test of polyamino resin waterproof coatings.

3. Results Assessment: When both samples are constantly cracked or have no broken marks, they are evaluated as no fracture.
