Low temperature flexibility meter for waterproofing membrane

Release time: October 24, 2016 popularity: six hundred and thirty-six

The low temperature flexibility tester is developed for testing the low-temperature flexibility of waterproof coiled materials, which conforms to the national standard GB / t328.14-2007. The standard clearly stipulates that the low-temperature flexibility test must adopt mechanical automatic test to avoid the influence of human factors. The low-temperature flexibility tester is the necessary equipment for testing institutions, waterproof coiled material manufacturers and testing product quality

Application of low temperature flexibility meter for waterproofing membrane

1. First, put the cooling tank into the low-temperature box, add the freezing liquid "use propylene glycol / water solution (volume ratio: 1:1) ethanol / water mixture (volume ratio: 2:1) lower than - 25 ℃ or lower than - 20 ℃ (volume ratio: 2:1), and then adjust the distance between the two circular axes of the compliance meter according to the test piece, that is, the diameter of the bending shaft + 2mm + twice the thickness of the test piece The upper end of the specimen is 10 mm below the freezing liquid level.

2. Connect the controller to the power supply. According to the temperature and time set in the standard, the temperature display is the temperature in the coolant. Press the start button. When the temperature reaches the set temperature, the supplier Hebei Dahong Experimental Instrument Co., Ltd. starts timing. When the set time is reached, the bending axis starts to rise at the speed of 360mm / min against the test piece, and stops when the bending axis stops At the end of the test, check whether the specimen has cracks. Press the down key to bend the shaft to the starting point.

Precautions for low temperature flexibility meter of waterproof membrane

1. It is strictly forbidden to touch the instrument shell directly during the operation of the compliance meter, so as to prevent frostbite at low temperature.

2. After the test, take the instrument out of the low-temperature box, wipe it clean and put it in a dry place.

3. The instrument must be grounded when using it.
