How to prevent harmful substances in wooden packing box
Generally speaking, these substances are divided into three kinds of fatigue: fungi, boring worms and marine boring animals. The most serious damage to wood is micro-organisms, which are mainly wood hiring bacteria and a small number of bacteria harm, so we are doing wood preservation, mainly to study the prevention of these fungi hazards. The growth of fungi must have four essential conditions: suitable temperature, adequate oxygen supply, adequate moisture, and nutrients suitable for the growth of fungi. If the four conditions are missing, they will prevent or prevent the erosion of fungi.
Wooden pallets are made of natural wood and must be handled in the production process, as there may be some harmful substances in them.
Wood preservation, quarantine and disposal are based on this principle. The use of dry kiln heat treatment of wood, from the temperature, moisture content damage fungal survival conditions, is an ideal and useful disposal methods. About the most natural fungi, when the wood moisture content below 20% or reaching saturation, the growth is limited; in 12 DEG, 46 DEG C, almost completely stopped the growth of fungi. As a result, we can heat the wood in a dry kiln and reduce the final moisture content to less than 20%, so as to achieve the purpose of insect killing and sterilization.
