How to prevent wood pallets from mildew
Wood pallet can be used in many places in our lives, such as production enterprises, logistics enterprises and large raw material semi-finished products production enterprises, these industries are a large number of wooden pallets, but wooden pallets are easy to mold, wood mold used in wooden pallets is caused by mold erosion of wood, different molds on the surface of the wood to form different colors of mold spots, Such as black, green, yellow red, blue green and so on. Mold likes a humid environment, so the end of the wood, board square, veneer that has not been dried is easy to mold, especially the sapwood part of the broadleaf wood. Once the wood pallets have moldy spots, it will not only affect the aesthetics of the pallets, but also bring certain economic losses to the enterprise. How can we prevent wood pallets from moldy? How to minimize the damage?
First of all, we need to understand why the wooden tray will be moldy.
Causes of wood mold:
General wooden tray, its water content is only less than 20%, when the water content of wood is higher than 20%, discoloration fungi and other microorganisms will multiply and grow. Therefore, if the wood after harvesting can be immediately dried to a moisture content below 20%, and the moisture content is always maintained below 20% during processing and use, it can effectively reduce the blue change, and in the process of storage, it can play a lot of good anti-mold effect, but this point most of our log plate companies due to transportation delays, Drying cycle and other factors make it difficult to dry immediately after harvesting. Therefore, the log end, board square, and wooden tray that have not been dried are easy to mold, and mold will invade the interior only under appropriate conditions.
Current ways to prevent mold:
1. drying: This method can solve most of the problems, but the cost is expensive, and easily lead to cracks in the wood, but special uses such as sealed packaging, warehouse humidity, export in the hot and humid environment at sea and so on will not work. Air drying (natural drying) is cheap but takes a long time.
2. heat treatment: to have special equipment, this method will increase the cost of treatment for manufacturers, although it can reduce the water content of wood, but can not solve the fundamental problem.
3. fumigation: This method is mainly for the export of wood packaging insecticide, and the period of validity is relatively short. Many mistakenly think that it is anti-mildew, in fact, it has no effect on the prevention and control of mold.
4. anti-mildew: The use of wood pallet anti-mildew agent to treat it, you can use water immersion or water spray treatment, the treated wood pallet is not easy to grow mildew. Wood mildew agent due to the use of a variety of antibacterial agents, it is a new efficient wood special mildew agent, which has high content, acid and alkali resistance, anti-loss, strong penetration, high adhesion, high humidity resistance, adapt to a wide range of wood and other advantages.
