Because the equilibrium moisture content of wood in Shanghai is 14.8%, the moisture content of floors used in Shanghai should be controlled at 7% ~ 14.8%.

process

(1) Natural drying takes about 30 ~ 40 days to make the water content reach about 30%.

(2) Artificial drying takes about 10 ~ 30 days to make the water content below 10%. At the same time, the pulp juice in wood is distilled, which balances the tissue of wood cell wall and makes the drying shrinkage tend to be stable and consistent.

(3) The curing treatment takes about 10 ~ 20 days. Through this process, the three purposes of wood drying are finally achieved.

Dry balance treatment is called heat treatment. The time of this treatment will vary with different materials, but it cannot be artificially shortened. There is a misunderstanding in sales that the heat-treated floor will never deform. In fact, this is impossible. No matter how it is treated, it is inevitable that the moisture content of wood changes below the fiber saturation point.
