Overview
The Ford viscosity cup (Ford-3 #) is a Viscometer made according to the American Society for Testing and Materials standard ASTM D 1200 and other regulations for the determination of inks, coatings, paints and other liquids Tack comparison. It consists of an aluminum cup with a capacity of about 100ml and a precision small hole at the bottom.
Features
1. Made according to ASTM D 1200, D333, D365 standards, the measurement results are reliable.
2. The cup body is made of cathode aluminum oxide material, and the nozzle is made of brass material, which is sturdy and durable.
3. The viscosity is determined by measuring the time of the fixed capacity liquid flowing out of the standard small hole, which is easy to operate.
Design capacity of about 100ml, flow hole diameter of 3.4mm, suitable for measurement of specific viscosity range.
Principle
Ford viscosity cup Tack data is obtained by measuring the time required for a certain volume (about 100ml) of the sample in the aluminum cup to completely flow out of the bottom standard hole. The outflow time (seconds) is directly related to the viscosity of the liquid.
Applications
Inks, paints, paints
Standards
ASTM D1200、ASTM D333、ASTM D365
Steps
1. Thoroughly clean the cup body and flow hole with a suitable solvent before use, and dry.
2. Select the appropriate cup number to ensure that the outflow time is 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 Ford viscosity cup holder to level.
5. Fill the sample, scrape the liquid level, plug the flow hole with your finger or baffle, and place the receiving cup below.
6. Release the finger or baffle, the liquid flows vertically and start the stopwatch, stop timing when the first breakpoint appears, 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, do not use metal tools to clean it.
Notice
• During use, it should be handled with care to avoid damage or deformation of the flow hole caused by drop or collision, which will affect the Measurement accuracy.
• 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 use a soft cloth to pass through the pull wipe to avoid using hard objects such as metal wires.
• Measurement results must be expressed in "seconds" at specified temperatures, converted to centistokes by reference to ASTM D 4212.
