TQC VF2090/VF2091/VF2185/VF2092/VF2093 immersion ISO Viscosity Cup is a portable ISO Viscosity Cup for viscosity testing of paints and paints imported from the Netherlands, which is suitable for testing in various laboratory occasions. The pore size and body size of the TQC ISO Viscosity Cup are produced and designed according to the relevant regulations of the standard din en ISO 2431 design, and the material is made of aluminum alloy, which is divided into five filter diameters of 3~8, and the viscosity range of the test is different.
The TQC Immersion ISO Viscosity Cup was originally designed for rapid viscosity and consistency assessment of products that conform to or are close to Newtonian mechanical properties, such as paints, paints, inks, pigments. Today's Viscosity Cups are produced according to a number of international standards, which have been developed over the years and specify not only the precise dimensional tolerances required in the process, but also the recording of their use and the data obtained.
TQC brand ISO Viscosity Cups are produced under strict quality control procedures and are engraved with a unique serial number. Most Viscosity Cups are made of aluminum-titanium alloy and stainless steel.
ISO Viscosity Cups are used to test the concentration of paints, paints and other similar products. The viscosity of the liquid is calculated and classified through the process of liquid flowing out of the hole under the Viscosity Cup. This method of measuring kinematic viscosity is generally to calculate the time of flow in minutes, and then use the disc viscosity calculator to convert it into dynamic viscosity units, so the Viscosity Cup is also called the outFlow Cup.
1) According to the standard, the temperature of the liquid to be measured is 23 degrees Celsius, and the temperature fluctuation needs to be minimized and cannot exceed +/- 0.2 degrees Celsius during the test.
2) Adjust the temperature of the liquid to be measured if necessary.
3) According to the specification table and the estimated viscosity range of the liquid to be measured, select the TQC immersion Viscosity Cup with appropriate pore size.
4) Slowly immerse the TQC VF2090/VF2091/VF2185/VF2092/VF2093 aluminum alloy immersion ISO Viscosity Cup into the paint viscosity until the top edge of the cup can be submerged.
5) Put a thermometer into the Viscosity Cup and measure the temperature of the test sample.
6) Remove the thermometer.
7) Hook the handle ring with your fingers to keep the cup vertical. Maintain a steady position and quickly lift the Viscosity Cup from the sample, and the timing begins when the TQC immersion ISO Viscosity Cup leaves the surface of the test coating. During the liquid flow process, the Viscosity Cup should be kept above the surface of the sample, no more than 15 cm.
8) Stop the timer when the liquid flow beam is interrupted for the first time.
