Testing Density of Amino Moulding Plastic‌

‌Materials Needed‌:

1. Precision balance (accuracy ±0.001 g)
2. Distilled water
3. Beaker or graduated cylinder
4. Thermometer (to measure water temperature)
5. Thin wire or non-absorbent thread (for suspending the sample)
6. Drying oven (optional, to remove moisture from the sample)

‌Procedure‌:

1. ‌Prepare the Sample‌:

   • Cut a small, regular-shaped piece of Amino Moulding Plastic (avoid porous or irregular edges).
   • Dry the sample in an oven at 50–60°C for 1–2 hours to remove moisture (if necessary). Cool it in a desiccator.

2. ‌Weigh the Sample in Air‌:

   • Use the balance to measure the dry mass of the sample (‌m_air‌) in grams (g).

3. ‌Weigh the Sample in Water‌:

   • Fill the beaker with distilled water and record its temperature (°C).
   • Suspend the sample in water using the thread, ensuring it is fully submerged without touching the container walls.
   • Measure the apparent mass of the sample in water (‌m_water‌) in grams (g).

4. ‌Calculate Density‌:

   • Use the formula:$$\text{Density (g/cm³)}=\genfrac{}{}{0ex}{}{m^{\text{air}}}{m^{\text{air}}-m^{\text{water}}}$$
   • Adjust for water density at the measured temperature (use standard water density tables if high precision is required).

‌Key Notes‌:

• ‌Avoid Air Bubbles‌: Gently tap the submerged sample to dislodge trapped air bubbles, as they can affect accuracy.
• ‌Temperature Control‌: Water density varies with temperature; measurements should be taken at 25°C for standard results.
• ‌Repeat Tests‌: Perform 3–5 trials and average the results to ensure reliability.

‌Alternative Methods‌:

• ‌Gas Pycnometry‌: For highly accurate results, use a gas pycnometer to measure volume via gas displacement (ideal for irregular shapes).
• ‌ASTM D792‌: Follow the standardized method for plastics density testing if compliance with industry norms is required.

By following these steps, you can accurately determine the density of Amino Moulding Plastic to assess material consistency and quality.
