Overview
The Ford cup is a Viscometer for measuring the viscosity of inks, coatings, paints, etc. It is made according to the American Society for Testing and Materials standards ASTM D 1200, D333, D365. It consists of an aluminum cup with a capacity of about 100 ml. There are small holes in the bottom of the cup. The viscosity is determined by measuring the time for a certain volume of sample to flow out of the hole.
Features
1. Made according to ASTM D 1200, D333, D365 standards, the measurement results are reliable.
2. The cup body is made of good aluminum, and the nozzle is made of brass material, which is sturdy and durable.
3. Simple design, easy operation, for Tack comparison determination.
4. The capacity is about 100ml, the diameter of the flow hole is 1.9mm, and the specifications are clear.
Principle
The Ford viscosity cup measures the Tack of the sample by measuring the time required for a certain volume of the sample in the aluminum cup to completely flow out of the bottom hole. The outflow time (in seconds) represents the viscosity value of the sample.
Applications
Determination of viscosity of inks, paints, etc
Standards
ASTM D1200、D333、D365
Steps
1. Thoroughly clean the cup body and flow hole with a suitable solvent before use, and dry.
Select the appropriate cup number to control the outflow time between 20 and 80 seconds.
Mix the sample well and filtrate, and adjust the temperature to (23 +/- 0.5 ° C) or the agreed temperature.
4. Adjust the Ford viscosity cup holder to center the horizontal bubble.
5. Fill the sample, scrape the liquid level, and put away the receiving cup.
6. Release the flow hole, start the stopwatch while the sample flows vertically, stop timing when the first breakpoint occurs, and record the time.
7. repeability measurement three times, take the average value as the final viscosity value.
8. Immediately after measurement, clean the cup with a suitable solvent to avoid cleaning with metal tools.
Notice
• Falling or collision may cause damage and deformation of the flow hole, affecting the Measurement accuracy, so be careful during use.
• Instruments should be calibrated annually (no need to calibrate in the first year after leaving the factory).
• Standard silicone oil should be used for calibrating and according to relevant national Measurement procedures.
• Pay special attention to the flow hole when cleaning, and wipe it with a soft cloth through the hole to avoid using wires or tools.
• Measurement results must be expressed in "seconds" at specified temperatures, converted to centistokes by reference to ASTM D 4212.
