Overview
JINGTIAN RVDV-2H digital display swirl/spin high temperature Viscometer is an instrument for measuring the viscosity of solid and liquid substances (such as asphalt, hot-melt adhesive, polyethylene (PE) wax, etc.) at room temperature. It can be used in a single machine, the data can be displayed directly, and the software can be optional to realize data collection and full monitoring of viscosity-temperature Linear dispersion. Measurement performance reaches the level of foreign congeneric products.
Features
1. Measured objects are highly targeted and suitable for asphalt, hot-melt adhesive, polyethylene (PE) wax and other high-temperature molten substances.
2. The display is intuitive, LCD liquid crystal with backlight, directly display parameters such as viscosity, Rotation speed, torque, rotor number, maximum measurable viscosity and temperature, DV-2 series can also display shear rate and shear stress.
3. Measurement accuracy is high, accuracy is +/- 1% (FS), reproducibility is +/- 0.5% (FS).
4. Excellent driving performance, high subdivision stepper motor, Rotation speed accurate, stable, support 0.1~ 200rpm stepless speed.
5. Precise temperature control, high temperature furnace adopts embedded integral heating, uniform heating, small thermal inertia, temperature control accuracy of +/- 0.1 ℃.
6. High degree of intelligence, continuous display of viscosity value, over-range sound and light alarm, and can be corrected by computer to improve accuracy.
7. Strong scalability, optional "data collection analysis and mapping software" for data collection and Linear dispersion analysis.
Principle
The instrument works on the principle of swirl/spin viscosity measurement. The instrument drives the rotor to swirl/spin in the sample and calculates the viscosity value of the sample by measuring the Tack resistance (torque) of the rotor at a specific Rotation speed. The high temperature furnace precisely heats the sample to melt it into a liquid state. The measurement data is processed internally by the instrument and displayed directly on the LCD screen, which can be transferred to computer software for further analysis and mapping of viscosity-temperature Linear dispersion.
Applications
Asphalt, hot-melt adhesive, polyethylene (PE) wax and other high-temperature molten substances viscosity measurement
Standards
The data did not mention specific compliance criteria
Steps
1. Prepare the sample to ensure it is in a measurable state (high temperature melting).
2. According to the estimated viscosity range, select the appropriate rotor (21 #, 27 #, 28 #, 29 #) and install it.
3. Pack an appropriate amount of sample (10 to 20 mL) into the sample container.
4. Set the target temperature of the high-temperature furnace and heat the sample.
5. Set the required measurement Rotation speed through the instrument (0.1~ 200rpm continuously variable speed).
6. Start the measurement, the instrument automatically displays parameters such as viscosity, temperature and Rotation speed.
7. After the measurement is completed, record the data. Optional software can be connected to the computer for data collection and Linear dispersion analysis.
Notice
Please ensure that the power supply is 220V 50Hz and is properly grounded.
* Select the appropriate rotor according to the estimated viscosity of the sample to ensure Measurement accuracy and avoid over-range.
The recommended sample capacity is between 10 and 20 milliliters.
Pay attention to safety during high temperature operation to avoid burns.
* Measurement range beyond the instrument will issue an alarm prompt, timely adjustment of Measurement conditions.
* Keep the rotor and sample cup clean to avoid affecting the measurement results.
* After long-term use or handling, it is recommended to calibrate.
