Low-temperature speed asphalt extension tester operating procedures:
1, the machine should be placed horizontally indoors, room temperature 0-25 °C, the relative humidity does not exceed 80%, no vibration, corrosive gas above the ground, has a good grounding protection. 2. Before use, check the depth of the water bath surface to meet the requirements of the test procedure. With all power switches turned off, turn on the power and check the stirring pump. Check whether the pulling power and the moving slide are working well.
3, open the temperature control switch, adjust the temperature control table to a desired temperature, start stirring, according to
4, the test requirements and the ambient temperature need, you can start cooling and heating control.
5, adjust the speed of the front governor to stretch, check the speed of the stretch to the required speed.
6, start stretching, the skateboard back to the left, ready to set the test mode on the skateboard
7. On the metal side of the tank, start the test by stretching. After all the specimens have been broken and broken, stop the power supply of the motor. When the number is broken, the reading is the result of the measurement.
8. When you stop using it, you should first turn off the power switch of each part, and finally cut off the power.
Rotary asphalt film oven operating procedures:
1. Power supply equipment: Overloaded safety devices should be installed in the power supply line for this box, and have a good grounding device, leveling the oven so that the turntable rotates on a horizontal surface. The angle of rotation with the horizontal plane must not exceed 3 degrees.
2, temperature adjustment: Install the thermometer (the thermometer mercury ball bottom about 6 mm from the top of the turntable) adjust the temperature controller to the desired temperature of 163 °C.
3. Close all switches above the switchboard, plug in the power plug, and turn on the power switch.
4, wait until the temperature of the entire studio to rise to the desired temperature (163 °C), you should check the reading of the working thermometer, you can adjust the temperature controller to obtain the correct temperature of the studio, constant temperature for 15 minutes, you can make the asphalt film measurement .
5. Place the sample holder containing the sample on the turntable, turn off the oven, and rotate the turntable. The constant oven temperature is 163°C.
6, in the operation of the box, indoor lighting can not be opened at will, so as not to affect the stability of the studio temperature.
7, after the completion, must cut off each switch.
