The dangers of wood blue stain
What are the hazards of wood blue stain? do you know?The following are the hazards of wood blue stain.
(1) Blue-stained wood is more prone to decay
Typically, wood bluestains first and then decays. In some cases, only obvious decay defects formed at a later stage of the bluestain may be seen. It can also be said that discoloration is a harbinger of decay.
(2) Discoloration increases the permeability of wood
Due to the penetration of blue fungal mycelium, many small pores are formed, which increases the permeability of wood. After drying, the hygroscopicity of blue-stained wood increases, and decay fungi are easy to grow and reproduce after absorbing moisture.
(3) If not prevented, the mycelium of cyanobacteria can penetrate deeply
To the depths of the wood, internal discoloration is formed. The internal discoloration of wood is due to the rapid drying of the wood surface infected with the discoloration fungus, and the dry wood surface does not provide enough moisture to the fungus, allowing the fungus to develop into colored hyphae.
In this way, the fungi on the wood surface are colorless (have not developed into colored mycelium), so no discoloration can be seen on the wood surface. However, the dry wood surface did not prevent the mycelium from spreading into the wood. If the interior of the wood is damp, the mycelium will continue to multiply and develop inside the wood, thus becoming colored mycelium, causing the interior of the wood to become discolored.
(4) Reduce the value of wood
Due to discoloration, the appearance of wood is not good-looking, users often refuse to accept such discolored wood or wood products, especially as decorative wood, furniture and other wood used in areas where the appearance of wood is more important, or require price reduction, so Commercially, preventing wood discoloration is an important aspect of maintaining the value of wood products.
