pest
Wooden blocks are often affected by pests during storage, transportation, and use. The natural enemies of wood are termites, longhorn beetles, and elephantiasis. If the wooden blocks are not properly protected, they will be damaged by these pests, thereby affecting the quality of the engineering wooden blocks.
Suggestion: If it is an outdoor wooden block, it should be soaked in preservatives to allow the preservatives to penetrate into the fibers of the wooden block, making the wood green from inside out, preventing corrosion, and resisting insect attacks.
crack
Cracks in wood are commonly referred to as cracking, as cracks appear between the fibers of the wood, which can lower the evaluation grade of the wood.
If the wooden block cracks when purchased, you can mix some sawdust with 520 glue and apply it to the cracked area. That's it.
decay
Under certain conditions, wood can be invaded by wood rot fungi and bacteria, which can cause changes in the color and structure of the wood, resulting in it becoming soft and fragile, appearing as pores, powders, or sponges. This is a manifestation of wood decay.
change color
The discoloration of wooden blocks is mainly caused by two reasons: chemical discoloration and fungal discoloration. Chemical discoloration is caused by the interaction between wood and chemical products, while fungal discoloration is caused by the invasion of fungal organisms into wood.
