Overview
PUSHEN Ford viscosity cup (model: Ford-2 #) is a Viscometer made according to the American Society for Testing and Materials standards ASTM D 1200, D333, D365, used to determine the viscosity of inks, coatings, paints and other materials. The product is refined from high-quality aluminum, with a capacity of about 100ml and a standard outflow hole at the bottom. The viscosity is characterized by the measurement of the time required for a certain volume of sample to flow out, which is convenient to use.
Features
1. According to ASTM D 1200, D333, D365 and other 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. Compact design, with a capacity of about 100ml, making it easy to operate and clean.
4. The viscosity value can be obtained by measuring the outflow time, and the method is simple.
Principle
Ford viscosity cup measures the viscosity of a sample by measuring the time it takes for a sample of a certain volume (about 100ml) in the cup to completely flow out of the bottom standard hole. The outflow time (in seconds) characterizes the viscosity characteristics of the sample. The longer the time, the higher the viscosity is usually indicated.
Applications
Inks viscosity determination, coating viscosity determination, paints viscosity determination
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 according to the estimated viscosity to control the outflow time between 20 and 80 seconds.
3. Stir the sample evenly and filtrate, and adjust the temperature to (23 +/- 0.5) ° C or the agreed temperature.
4. Adjust Ford viscosity cup holder to level.
5. Plug the flow hole with your finger or baffle, fill the cup with the sample, and scrape the liquid level with a scraper.
6. Release the finger or baffle to allow the sample to flow vertically, and immediately start the stopwatch timing.
7. Stop timing when the flow appears at the first breakpoint and record the outflow time (seconds).
8. repeability measurement three times, take the average value as the final viscosity value.
9. 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.
• The cup body and flow hole must be thoroughly cleaned before and after each use to ensure that there is no residual sample.
• Do not use metal cleaning tools or wires when cleaning to prevent scratching the flow hole. If there is dry sediment in the flow hole, it should be carefully cleaned with solvent softening before using a soft cloth.
• The instrument is recommended to be calibrated regularly once a year (no need to calibrate in the first year after leaving the factory). The calibrating needs to use standard silicone oil and be carried out according to the relevant national Measurement procedures.
• Measurement results (seconds) must be recorded at the specified temperature, for conversion to centistoke (cSt) units, please refer to ASTM D 4212 standard.
