Customized wooden pallets made of poplar boards and wooden blocks for import and export, with anti-corrosion properties for wooden pallets

Description :

　　What is the fundamental principle behind the dryness of wooden planks? There are two types of moisture in wooden planks: self absorbed water and absorbed water. The moisture within the large capillary fragments composed of cell cavities is called spontaneous water, and its increase or decrease only reflects the weight of the wooden board, rather than its essence; The moisture within the micro capillary fragments composed of cell walls is called water absorption, and its transformation not only causes the wood to shrink and expand, but also reflects the other physical and mechanical properties of the wood.

　　The dryness of wooden planks is to remove the inherent and absorbed water in the wood, in order to meet the opposite requirements of use and quality. There are certainly various ways to dry wood, but the fundamental principle is independent, which is to apply the moisture gradient along the thickness of the wood, as well as the external large and internal small water vapor pressure difference generated after heating, to drive moisture to gradually move from the outside to the inside in both liquid and vapor states, and boil from the surface of the wood to the outside; The intensity of external moisture movement should be in harmony with the intensity of external moisture boiling, so that the wood dries in a balanced manner from the surface to the interior.

　　The conservative steam drying chamber undergoes a drying process where a high heat (after 100 ℃) and high heat (full or close to full) eczema atmosphere is repeatedly passed through the wood pile, transferring heat to the wood. When the wood and its moisture are heated to a certain level, according to the rules of dryness standards, the measurement and humidity of the medium are increased to induce the moisture in the wood to boil from the surface, which is the beginning of dryness. Then, following the order of the dry standard rules, gradually improve the measurement of the medium and increase the humidity, so that the moisture in the wood is gradually transferred to the outside until the dry is over. During the dry process, it should be possible to eliminate or increase internal stress, cracking, and deformation without elevating the physical and mechanical properties of the wood, in order to ensure the quality of dryness.
