I. Overview

Low temperature bender

It is suitable for low temperature bending test of polymer waterproofing membrane

,

Also suitable for the determination of low temperature flexibility of waterproof coatings

Suitable for coil size

50X100mm

or

100X50mm

Or coated test piece prepared by polymer waterproof coating

100X25mm.

two,

The main technical parameters:

1,

Specimen size:

100*50mm

;

2,

Bending angle:

180°

3,

It is suitable for low temperature bending test of waterproof coiled material, and is suitable for low temperature flexible measurement of waterproof coating.

three,

experiment method:

1

In the standard environment, the thickness of the sample is measured by thickness measurement, and the thick surface of the sample should have no obvious defects.

2

, the weather resistance of the sample is completely facing outward

180

Degree

50mm

(or

25mm

) The wide edges are flush and flush, and ensure that no misalignment occurs, using a clip or stapler or

10mm

A wide tape secures the edges.

3

Adjust the spacing between the upper and lower plates to three times the thickness of the sample.

4

Open the upper and lower plates, place the sample flat on the upper and lower plates, the overlapping side faces the rotating shaft, and the distance from the rotating shaft

20mm

,(or

25mm

)

5

Will be placed in the cryostat together with the sample and kept at the specified temperature.

1

Hours (or

2

Hours) and then at

1S

Press the flat plate on the bender to reach the adjusted pitch and keep

1S

, take the sample out.

6

After returning to room temperature, observe whether the bend of the sample is broken, or use a magnifying glass to observe whether the sample is bent or not.

7

When two or three specimens are not broken or crack-free, they are evaluated as no cracks.
