Scope of application:

Special equipment used for measuring the gelatinous layer index of bituminous coal (three indicators of gelatinous layer thickness Y, shrinkage X, and volume curve). Complies with the requirements of the national standard GB/T479-2000 "Method for Determining the Index of Bituminous Coal Colloidal Layer".

Functional features:

1. The bidirectional communication between the computer and the controller enables comprehensive monitoring of the control equipment.

2. Automatically control and display the heating temperature of single or double furnaces.

3. Automatically measure and display the shrinkage of coal samples from single or double furnaces.

4. Automatically draw the volume curve of a single or double furnace.

5. Automatically draw the curve of furnace temperature variation over time.

6. Automatically fill in the furnace temperature before and after every ten minutes.

7. At the inflection point of the volume curve, an alarm is triggered to prompt the laboratory personnel to select the operation modes of starting, stopping, and silencing the equipment.

8. Manually detect the data of the adhesive surface, input it into the computer through the keyboard for saving, automatically draw the upper and lower adhesive surface curves, and calculate the thickness of the adhesive surface.

9. Automatically calculate test results and print out test records and reports.

10. Store previous test data for querying and printing.
