The significance of heat treatment of wood pallet: it can change the performance of wood and improve the performance of pallet. Improve the bending strength and rigidity of wooden pallet.
The international standard of wood moisture content is 22-26%. After heat treatment, the excess moisture of the wood pallet is dried and formed, which reduces the moisture content and eliminates the internal stress, making the bearing capacity of the heat treated wood pallet stronger and more stable.
The central temperature of wood must be at least 56 ℃ for more than 30 minutes
(1) The minimum fumigation temperature should not be less than 10 ℃ and the minimum fumigation time should not be less than 16 hours.
(2) : as long as the kiln drying, chemical pressure soaking or other treatment methods meet the requirements of heat treatment, they can be regarded as heat treatment. Such as chemical pressure impregnation, steam, hot water or dry heat can be used to meet the technical requirements of heat treatment.
If the wooden pallet needs to be exported, the validity period is the same as that of the fumigation pallet, which is 21 days.
The wood packaging exported to China by the United States, Canada, European Union, Japan and Australia needs to be fumigated (disinfected), and the official fumigation (disinfection) certificate must be issued to the United States and Canada.
