Settleable Solids and Solids Passing No. 10 Sieve Test
- Three liquid deicers after 7 days in the freezer.
- Closeup of settleable solids at the bottom of the cone.
- Glass rod used to probe for depth of the settled solids in a dark deicer
- Marking the displacement due to the settled solids.
- Measuring the displacement volume based on the marked rod. Volumes that exeed 10 ml fail the test.
- Pouring the deicer through a No. 10 sieve to capture large solids.
- Settled ice crystals or frozen chemical shown on top of the sieve.
- Transferring the solids through a funnel to a graduate cylinder.
- Measuring the volume of the settleable solids in a graduated cylinder. Solutions/Solids that exceed 10 ml fail the test.
Storage, Delivery, and Testing the Density with a Hydrometer
- Liquid chemical storage tanks.
- Off loading a liquid deicer from a tanker truck.
- Pump for transferring liquid chemical to application trucks.
- Sample port for taking a sample during delivery.
- Checking the temperature of the solution.
- Hydrometer and Graduated Cylinder used to determine the density of the product during delivery.
- Using the hydrometer to measure the material density.
Corrosion Test
- Corrosion instrument with prepared test solution that determines the Percent Corrosion Effectiveness of deicers by dipping coupons in and out for three days.
- Closeup of a steel coupon that is just starting to corrode.
- Appearance of coupons and solutions of Distilled Water (left) and a 3% Salt solution (right).
- Closeup of coupon showing corrosion and solution showing darkening color.
- Coupons after testing showing corrosion. Notice the amount of corrosion between distilled water, salt, and an inhibited product.
Lab Equipment
- FT- Infrared Spectrometer to determine the organic makeup of chemicals.
- X-Ray Fluorescence Spectrometer used to determine elemental composition of materials.
- Atomic Absorption Spectrometer used to determine the concentration of liquid salts and trace metals.
- Laboratory glassware and chemicals used for testing materials.
