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.
