Today your old friend Qingdao Senyu Environmental Protection Technology Co., Ltd. tells you the material composition and moisture content of wooden pallets.
Our Inspection-Free Compressed Wood Pallet products have become the industry leader with advanced production technology and excellent quality!
The wooden pallet is made of logs, which is dried and shaped to reduce moisture and eliminate internal stress. Then it is cut, planed, broken, edged, sanded and other finishing processes to form a profile plate. Shooting nails (in some cases, nut structure) binds the profile plates into semi-finished trays, and finally carries out finishing, anti-skid treatment and sealing wax treatment. Wooden pallets are the most widely used pallets today. A pallet is a horizontal platform device used for containerization, stacking, handling and transportation to place goods and products as unit loads. Generally made of wood, metal, and fiberboard, it is easy to load, unload, and handle unit materials and small quantities of materials.
Log materials: At present, the materials of domestic wooden pallets mainly include pine, iron shirt, fir and other miscellaneous hardwoods. Different materials represent different performances of pallets. It is clearly stated in the European pallet standard that aspen cannot be used.
Moisture content: The moisture content of the pallet log affects the shrinkage and deformation of the pallet, and even cracks. The application of high standard pallets has strict control of its moisture content index. The European standard for wooden pallets stipulates that the moisture content cannot exceed 22% of the mass of the wood in the dry state. It is defined as a small defect within the range of 22% to 26%, and if it exceeds 26%, it is unqualified.
Wood pallet: A pallet made from natural wood. It is the most widely used now because it is cheap and strong.
Main parameters: length/width/height/length/width/height error/diagonal error/rated load/maximum stacking layers/deflection/surface anti-skid coefficient
Advantages: high accuracy, not easy to deform, reinforced with high-strength screws, no nails, good firmness.
