Asphalt standard viscometer

Asphalt standard viscometer use and scope of use:

According to the industry standard of the Ministry of Communications

T0621

The specification of the asphalt standard viscosity test is used to determine the viscosity of liquid petroleum asphalt, coal pitch, and emulsified asphalt in a flowing state. It is suitable for measuring the viscosity of viscous petroleum asphalt, liquid petroleum asphalt and soft coal tar pitch with low consistency. The viscosity is the sample flowing from the drain hole of the standard viscometer at the specified temperature.

Indicates that the viscosity of the sample is measured to divide the label of the sample.

How to use the asphalt standard viscometer:

Before use, check whether the parts are normal, and pay attention to whether the water tank is clean and there is no obstacle in the oil tank hole. Test in the following order.

1

Good water injection funnel, the injected water can not exceed the specified engraved line.

2

Remove the oil sump cover.

3

Select the diameter of the oil drain hole according to the marking and technical specifications of the test asphalt.

4

Use a metal lever to block the drain hole.

5

Take the asphalt sample into the beaker and heat it to melt and pour into the oil tank.

6

Cover the oil cup cover.

7

According to the requirements of various asphalts, set the temperature setting: press and hold the ↑ or ↓ button to release the temperature when the temperature displayed in the temperature window reaches the set value: turn on the power switch and start heating; start the stirring switch when the temperature reaches Constant temperature
