Decay Resistance of Bamboo Oriented Strand Board Pretreated with Copper-based Preservatives
To enhance the decay resistance of bamboo oriented strand board (OSB) products, the strands were dipped in solutions of alkaline copper quat (ACQ) and copper azole (CA) and bonded with phenol formaldehyde resin into two types of OSB panels, i.e., panels with 100% treated strands and those with treat...
