Industrial Insulation Water Absorption Test

Conducted at Island Pacific Academy

Kapolei, Hawaii, USA

    Monday, September 28, 2008

    The “water absorption test” was performed on three industrial insulation samples. The products tested were Calcium Silicate, Perlite and RCUI 99.7% water resistant HITLIN™ (High Temperature-Layered-Insulation).

     

    Each sample consisted of a 2-inch square block of the subject material. The blocks were dry and weighed before placing them into individual beakers of water. The rate of water absorption was observed. The test lasted ten (10) minutes. Samples were re-weighed after testing then allowed to “dry out” for 18 hours. At that time, the samples were re-weighed then, placed in an oven that was set to 500°F. After one (1) hour, the samples were pulled from the oven and weighed one final time. Observational results are provided in the following table.

    1. All three samples floated at beginning of the test. The Perlite sample sank to the bottom of the beaker in 2 minutes. The Calcium Silicate sample sank to the bottom of the beaker in 9 minutes 10 seconds. The test was suspended after 10 minutes. The HITLIN™ sample was still afloat.

    2. When samples were pulled from water, both Perlite and Calcium Silicate left the water discolored with residue that dissolved from the samples.

    3. Calcium Silicate and Perlite samples became completely saturated with water and sank. Their weights increased by a factor of four (4). HITLIN™ weight went up by only half that amount.

    4. After one (1) hour of oven drying at 500°F, the HITLIN™ sample completely dried out while the Calcium Silicate and Perlite samples still contained twice their weight in water.

    5. After one (1) hour of oven drying at 500°F, the HITLIN™ sample completely dried out while the Calcium Silicate and Perlite samples still contained twice their original weight in water.
    Conclusions:

    Water resistant HITLIN™ has a much higher resistance to water than Calcium Silicate or Perlite. HITLIN™ sample dries out much faster than other samples when put back into service after water exposure. Long term water retention in Calcium Silicate and Perlite would negatively affect thermal conductivity of those products. HITLIN™ performance is significantly superior to other samples when exposed to water .
