Since the wood moisture content in Shanghai is 14.8%, the moisture content of the floor used in Shanghai should be controlled at 7% to 14.8%.
process
(1) Naturally drying, it takes about 30 to 40 days to make the water content reach about 30%.
(2) Artificial drying takes about 10 to 30 days to make the water content below 10%. At the same time, the slurry in the wood is distilled out to balance the cell wall structure, and the shrinkage performance tends to be stable.
(3) Rehabilitation treatment takes about 10 to 20 days. Through this process, the three purposes of wood drying are finally achieved.
The dry balance treatment is a so-called heat treatment. The length of this treatment will vary from material to material, but it cannot be shortened artificially. There is a misconception in sales that the heat-treated floor is “never deformedâ€. In fact, this is impossible. Regardless of the treatment, the swelling and shrinkage of the wood at a change in the moisture content below the fiber saturation point is inevitable.
