TEST: PLASTIC LUMBER WATER ABSORPTION RATES
24 HOUR SUBMERSION |
BEFORE SUBMERSION IN
WATER FOR 24 HOURS: AVERAGE DIMENSIONS OF 4 SPECIMENS:
6.031"L X 5.813"W X 1.938"TH.
AFTER SUBMERSION IN WATER FOR 24 HOURS: AVERAGE DIMENSIONS OF 4
SPECIMENS:
6.031"L X 5.813"W X 1.938"TH.
CONCLUSION 1: SIZE
OF SPECIMENS WERE UNCHANGED
AFTER 24 HOUR SUBMERSION.

CONCLUSIONS: "The results
of this experiment, while not surprising, are
very favorable. It
would be expected that the specimens of Recycled lumber would not absorb
water during submersion in water. After all, the
materials from which this recycled lumber is manufactured were once used
to make liquid containers... The fact that
recycled lumber does not absorb water will allow it to be used in
situations where wood would not be suitable." |
